High efficiency enclosed plate filter

Abstract

This utility model discloses a high-efficiency closed plate filter, including a filter tank, filter screens, quick-release bolts, and a vibration mechanism. The filter tank consists of a cylindrical body and a top cover connected by quick-release bolts to form a closed container. A conical end cap is installed at the bottom of the cylindrical body. Filter screens are installed inside the filter tank, and a collection pipe is connected below the filter screens. The filter screens are composed of multiple layers of stainless steel mesh, with filtrate flow channels between adjacent stainless steel meshes. The filter screens are fixed to the cylindrical body by a fixing plate. A vibration slag removal mechanism is installed on the outside of the cylindrical body in the horizontal direction of the fixing plate. The bottom of the conical end cap is a slag discharge port. When filtering materials such as oils and chemical products, the filter press of this application uses a vibration slag removal mechanism installed on the side of the filter screens. The reciprocating vibration of the vibrating head is transmitted to the filter screens, causing the filter cake attached to the filter screens to fall off. A slag discharge valve is installed at the bottom of the cylindrical body. The opening of the slag discharge valve is adjusted according to the amount of slag. This dual slag discharge helps to solve the problem of slag removal from the deposited filter cake.

Description

Technical Field

[0001] This utility model relates to a filter, specifically a high-efficiency closed plate filter. Background Technology

[0002] In modern industrial production, filters are needed to filter materials such as oils and chemicals. Filters are deep-filtration structures, small in size, easy to operate, and have a wide range of applications.

[0003] However, existing plate-type closed filters mainly have the following problems: filter cake is prone to accumulate in the lower horizontal collection pipe, and it accumulates and blocks the filter cake from falling off during de-cakeing, requiring manual cleaning; the installation of filter bags is limited by space, resulting in uneven filter cake and affecting filtration stability.

[0004] Therefore, the filter was improved without increasing its size. Utility Model Content

[0005] To address the problem of filter cake deposition, this invention provides a high-efficiency closed plate filter with dual slag discharge, improving cleaning efficiency.

[0006] This utility model provides the following technical solution:

[0007] A high-efficiency closed plate filter includes a filter tank, filter screens, quick-release bolts, and a vibration mechanism. The filter tank consists of a cylindrical body and a top cover connected by quick-release bolts to form a closed container. A conical end cap is installed at the bottom of the cylindrical body. Filter screens are installed inside the filter tank, and a collection pipe is connected below the filter screens. The filter screens are composed of multiple layers of stainless steel mesh, with filtrate flow channels between adjacent stainless steel meshes. The filter screens are fixed inside the cylindrical body by a fixing plate. A vibration slag discharge mechanism is installed on the outside of the cylindrical body in the horizontal direction of the fixing plate. The bottom of the conical end cap is a slag discharge port.

[0008] Furthermore, the vibrating slag discharge mechanism includes a vibrating head and a vibrating seat, the vibrating seat being installed on the outer wall of the cylinder, and the vibrating head being installed on the vibrating seat.

[0009] Furthermore, the outer periphery of the filter screen is a rectangular or circular cross-section frame made of stainless steel.

[0010] Furthermore, a slag discharge valve is installed at the slag discharge port.

[0011] Furthermore, a locking mechanism is installed at the upper and lower flanges of the cylinder and the top cover. The locking mechanism includes a pin, a hinge bolt, and a locking handwheel. The lower end of the hinge bolt is connected to the flange of the cylinder through the pin, and the upper end of the hinge bolt passes through the flange of the top cover and is tightened by the locking handwheel.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When the filter press filters materials such as oil products and chemical products, a vibrating slag removal mechanism is installed on the side of the filter screen. The reciprocating vibration of the vibrating head is transmitted to the filter screen, thereby causing the filter slag attached to the filter screen to fall off. A slag discharge valve is installed at the bottom of the cylinder. The opening of the slag discharge valve is adjusted according to the amount of slag. The dual slag discharge helps to solve the problem of slag discharge of the deposited filter cake. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 The high-efficiency closed plate filter of this utility model includes a filter tank 1, filter screen 6, quick-release bolts 4 and a vibration mechanism. The filter tank 1 is a closed container formed by connecting a cylinder 7 and a top cover 9 through quick-release bolts 4. A conical end cap 3 is installed at the bottom of the cylinder 7. The filter screen 6 is installed inside the filter tank 1. A collection pipe 5 is connected below the filter screen 6. The filter screen 6 is composed of multiple layers of stainless steel mesh. The spaces between adjacent stainless steel meshes are filtrate channels. The filter screen 6 is fixed inside the cylinder 7 by a fixing plate 2. A vibration slag discharge mechanism is installed on the outside of the cylinder 7 in the horizontal direction of the fixing plate 2. The bottom of the conical end cap 3 is a slag discharge port 14.

[0019] The vibrating slag removal mechanism includes a vibrating head 10 and a vibrating seat 11. The vibrating seat 11 is installed on the outer wall of the cylinder 7, and the vibrating head 10 is installed on the vibrating seat 11. The reciprocating vibration of the vibrating head 10 is transmitted to the filter screen 6, thereby causing the filter slag attached to the filter screen 6 to fall off smoothly.

[0020] The filter screen 6 is surrounded by a rectangular or circular cross-section frame made of stainless steel. The frame is more corrosion-resistant and robust.

[0021] A slag discharge valve 15 is installed at the slag discharge port. The opening of the slag discharge valve is adjusted according to the amount of slag.

[0022] Locking mechanisms are installed at the upper and lower flanges of the cylinder 7 and the top cover 9. The locking mechanisms include a pin 12, a hinge bolt 13, and a locking handwheel 8. The lower end of the hinge bolt 13 is connected to the flange of the cylinder 7 through the pin 12, and the upper end of the hinge bolt 13 passes through the flange of the top cover 9 and is tightened by the locking handwheel 8.

[0023] When filtering materials such as oils and chemicals, the filter screen 6 is equipped with a vibrating slag removal mechanism. The reciprocating vibration of the vibrating head 10 is transmitted to the filter screen 6, thereby causing the filter slag attached to the filter screen 6 to fall off. A slag discharge valve 15 is installed at the bottom of the cylinder 7. The opening of the slag discharge valve is adjusted according to the amount of slag. The dual slag discharge is beneficial to solving the problem of slag discharge of the deposited filter cake. In order to make the vibration slag discharge more thorough, the amplitude of the vibrating head needs to be adjusted according to the viscosity properties of the filter slag.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
