Description

Technical Field

[0001] The utility model relates to the technical field of filter materials, in particular to energy-saving and low-resistance composite new filter materials. Background Art

[0002] Filter media is a material used to filter liquids or gases, usually composed of fibers, particles or membranes. The function of the filter media is to separate solid particles or other impurities suspended in the liquid or gas to make the outflowing liquid or gas clearer and purer. Common filter media include filter paper, filter cloth, filter screen, activated carbon, ceramic membrane, etc. Filter media are widely used in the production processes of chemical, pharmaceutical, food, beverage and other fields.

[0003] In the prior art, a Chinese patent with publication number CN205672671U discloses a composite needle-punched filter material. It solves the technical problems that the existing needle-punched filter material has too simple a structure, no anti-oxidation and antibacterial properties, can only be used in a single environment, and has a single use. The composite needle-punched filter material includes a base fabric layer, the base fabric layer is a plain cloth woven by a rapier loom using glass fiber, an upper mixed surface layer is arranged on the upper side of the base fabric layer, and the thickness ratio of the upper mixed surface layer to the base fabric layer is 3:2, a lower mixed surface layer is arranged on the lower side of the base fabric layer, and the thickness ratio of the lower mixed surface layer to the base fabric layer is 4:3, an anti-oxidation layer is arranged on the upper mixed surface layer, and the thickness ratio of the anti-oxidation layer to the base fabric layer is 1:6, and an anti-bacterial layer is arranged on the lower mixed surface layer, and the thickness ratio of the anti-bacterial layer to the base fabric layer is 1:10; a transparent insert plate for placing a detailed sheet is arranged on the anti-oxidation layer through a detachable structure, and an insert is provided on the transparent insert plate.

[0004] The above-mentioned filter material is filtered through a multi-layer structure during use. However, in actual use, when the filter material is filtering air or liquid, the filtered impurities will adhere to the surface or inside of the filter material. As the impurities continue to accumulate, the permeability of air or liquid in the filter material decreases (that is, the resistance becomes greater). At this time, the conveying pump body needs to consume more energy to convey the air or liquid filtered by western medicine. Utility Model Content

[0005] The utility model aims to provide a new energy-saving and low-resistance composite filter material to solve the problem in the above-mentioned background technology that impurities accumulate to increase resistance and thus increase equipment energy consumption.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: energy-saving low-resistance composite new filter material, including a square-shaped installation frame, the upper and lower outer surfaces of the installation frame are provided with installation grooves for docking equipment, and also include:

[0007] A composite filter material for filtering gas is installed inside the installation frame, and positioning columns are fixedly installed at the four corners of the installation frame, and the positioning columns and the positioning holes opened at the four corners of the composite filter material form a through-type clamping installation structure;

[0008] The left and right sides of the installation frame are provided with cleaning mechanisms for cleaning the surface of the composite filter material. The cleaning mechanisms include pressurized nozzles fixedly installed on the inner sides of the left and right ends of the installation frame.

[0009] Preferably, the installation frame is assembled by docking an upper frame and a lower frame that are symmetrically arranged up and down, and the upper frame and the lower frame are fixedly connected by a connector installed with threads on the outer surfaces.

[0010] Preferably, the composite filter material is provided with three parts including a front layer, a middle layer and a rear layer, and the front layer, the middle layer and the rear layer are fixedly connected by pressing.

[0011] Preferably, the front layer is set to be a cellulose filter material, the middle layer is set to be an activated carbon material, and the rear layer is set to be a synthetic polypropylene material.

[0012] Preferably, a return spring for pushing the composite filter material is installed on the rear exterior of the positioning column, and a limiting nut for preventing the composite filter material from falling off is threadedly installed on the front end of the positioning column.

[0013] Preferably, the cleaning mechanism further comprises an air blowing bag fixedly mounted on the lower inner surface of the lower frame body and a storage tank provided at the lower end of the lower frame body, and inner cavities are provided inside the side surfaces of the lower frame body and the upper frame body.

[0014] Preferably, the inner cavity and the pressurized nozzle are interconnected, and the inner cavity also forms a communicating structure with the inflation airbag through a connecting pipe.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the energy-saving low-resistance composite new filter material adopts a new structural design, and its specific contents are as follows:

[0016] 1. The rich and deteriorated filter material is installed with the installation frame through the engagement between the positioning hole and the positioning column, and the composite filter material is set as a multi-layer structure, which can achieve better filtering effect;

[0017] Furthermore, the installation frame is configured as a splicing structure, that is, the installation frame is divided into an upper frame and a lower frame, and the upper frame and the lower frame are fixedly installed by connecting parts. This structure allows the device to be disassembled as a whole when disassembling and replacing the composite filter material, which is convenient for the staff to replace the operation.

[0018] 2. The composite filter material slides through the positioning column. When working, the thrust of gas or liquid passing through pushes the composite filter material to move backward. When stopping working, the elastic action of the reset spring pushes the composite filter material forward to reset.

[0019] Furthermore, the composite filter material squeezes the airbag when it moves forward under the thrust of the return spring, so that air enters the inner cavity through the connecting pipe and is finally ejected from the pressurized nozzle, thereby achieving the purpose of cleaning the surface of the composite filter material and reducing the resistance increased by blockage.

[0020] The cleaned impurities fall into the storage tank for collection to avoid being attached to the composite filter material again. BRIEF DESCRIPTION OF THE DRAWINGS
