Melt pump and screen changer

Through continuous technical research and innovation, the company can provide the industry with hydraulic plate mesh changer (petrochemical polymerization special type), high-performance hydraulic double column mesh changer, hydraulic double column large area mesh changer, manual mesh changer and other products. On the basis of ensuring good sealing performance, effective heating, real-time measurement and providing quality assurance, different types of net changer products have the following characteristics:

1, hydraulic plate mesh changer (petrochemical polymerization special model) : this type of product uses hydraulic drive, can be designed as a single plate or double plate, can provide a maximum mesh area diameter of 500mm, can choose electric heating or oil heating, and explosion-proof configuration; This model is also available in a cost-effective version designed for recycled pelletizing applications, with electric heating and a large high pressure rapid hydraulic change system for a cost-effective melt filtration solution.

Compared with other types of screen changers, the plate series has the advantages of shorter flow channel, simple operation, etc., suitable for all kinds of polymers after polymerization filtration, material viscosity, poor flow can also be used this type.

2, high-performance hydraulic double-column mesh changer: This type of product has a small volume, short material residence time, online replacement of the filter screen, without interrupting the flow of material, with the suction exhaust mechanism design, and to ensure the stability of melt temperature and pressure during the mesh change process; The filter medium can use common metal braided filter net, and the filter net is directly treated as solid waste after use, eliminating the problem of waste gas and hazardous waste generated by incineration and chemical cleaning after the use of the filter core, which is a new solution of melt filtration in the production process of chemical fiber and polymer polymerization; This series of products can provide plunger diameter of 90mm to 300mm models and automatic backwash type products;

Compared with other types of net changers, the performance of this type of product has been improved in more aspects, while increasing the effective filtration area, the actual filtration channel has not increased, with small size, short material residence time, low energy consumption and other advantages, can achieve all kinds of polymer melt online filtration, material viscosity, poor fluidity, corrosive can also be used this type.

3, hydraulic double column large area net changer: this type in the same plunger diameter and filter size, can provide more than 4 times the effective filter area, because this type is on the basis of ordinary double column net changer, further optimize the design of the filter area, the traditional plane filter design to surround the design of the plunger; It has the advantages of large filtering area, small shape, low energy consumption, and can also use common metal braided filter as the filter medium. At present, Henan Bate can provide a single filter area of 300 to 8000cm of this type of product, suitable for the maximum yield of 20 tons/hour of melt filtration process; This type can also provide products with automatic backwashing function according to customer process requirements;

Compared with other types of screen changers, this type of small structure, large filtration area, suitable for high yield, high precision melt flow is good online filtration process.

4. Manual net changer. The series is a manual lever to make the two filter blocks alternately enter the working position and change the mesh position, using flexible sealing, with superior sealing performance, compact structure, easy installation, simple operation, removable mesh board and other advantages.

Compared with other types of net changers, this series of net changers is more cost-effective, without hydraulic control system, which can save a lot of space resources for users. Suitable for low yield plastic extrusion production.

5, four network circulation type hydraulic mesh filter. This type of product is driven by a hydraulic system, which is mainly composed of a main body and four separate filters, and the mesh block moves individually and works in turn. The filter plate is provided with preheating work and exhaust structure. When changing the net, the material pressure fluctuation is small, which can ensure the continuous and stable production of products.

Compared with other types of mesh changer, this type of filter plate preheating work, yellow mesh is the material pressure, material flow, material temperature balance transition, especially suitable for high transparency and high precision products.
