Description

Technical Field

[0001] This utility model belongs to the field of degreasing agent production technology, specifically relating to a filtration device for degreasing agent production. Background Technology

[0002] In the production of degreasing agents, filtration devices are crucial for ensuring product purity. However, existing filtration devices generally have significant drawbacks in practical use. Currently widely used integrated filtration equipment typically has its filter screen fixed inside the housing. During long-term operation, trapped filter residue continuously accumulates on the filter screen surface, gradually forming a dense clogging layer. This leads to a continuous increase in filtration resistance and a significant decrease in filtration efficiency.

[0003] This clogging not only slows down the filtration speed and increases energy consumption, but more seriously, it affects the clarity of the degreasing agent and the quality of the product. Because the unit uses a one-piece molded structure, cleaning and maintenance become extremely difficult. Operators cannot directly and effectively clean the internal filters; often, the entire filter unit needs to be disassembled, or even forced cleaning is required using external tools. This process is time-consuming, labor-intensive, and can easily cause mechanical damage to the filters. Furthermore, during cleaning and maintenance, the entire production line must be shut down, severely impacting the continuity and stability of production. Utility Model Content

[0004] The purpose of this invention is to provide a filtration device for the production of degreasing agents, which has good filtration effect and is easy to maintain.

[0007] The filtration mechanism includes a first filter screen, a second filter screen, and a third filter screen fixedly installed at the bottom of the cover plate. The first filter screen, the second filter screen, and the third filter screen are all tubular. The first filter screen, the second filter screen, and the third filter screen are coaxially nested from the inside to the outside, and the filter pore size decreases layer by layer from the inside to the outside in the radial direction. The bottom of the first filter screen, the second filter screen, and the third filter screen are all in tight contact with the top of the mounting plate.

[0008] Preferably, a discharge pipe is provided through and fixed on the mounting plate, the bottom of the discharge pipe passes through the filter barrel and extends outward, and a valve is provided on the discharge pipe.

[0009] Preferably, the fixing component includes a locking block slidably disposed on the top of the filter barrel, the top of the cover plate has a locking groove adapted to the locking block, the locking block is inserted into the locking groove, and the locking block is connected to an elastic component.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a multi-layered tubular filter system with coaxially nested filter screens of progressively smaller pore size from the inside out. This system enables multi-stage filtration of the degreasing agent, from coarse to fine, effectively improving filtration accuracy and efficiency. Furthermore, the multi-layered filter screens are integrated into an openable cover plate, along with a quick-fixing component, allowing for convenient installation and removal of the filter screens.

Detailed Implementation

[0022] 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.

[0023] Example 1:

[0024] Please see Figure 1 - Figure 5 As shown, a filtration device for degreasing agent production includes: a filter barrel 1, an installation port on the top of the filter barrel 1, a cover plate 2 inside the installation port, two symmetrically arranged fixing components between the filter barrel 1 and the cover plate 2, an extrusion component inside the filter barrel 1, an installation plate 3 fixedly installed inside the filter barrel 1, a feed pipe 4 passing through and fixedly installed on the installation plate 3, a connecting block 5 passing through the bottom of the feed pipe 4 and fixedly installed on the filter barrel 1, and a filtration mechanism between the cover plate 2 and the installation plate 3.

[0025] The filtration mechanism includes a first filter screen 6, a second filter screen 7, and a third filter screen 8 fixedly installed at the bottom of the cover plate 2. The first filter screen 6, the second filter screen 7, and the third filter screen 8 are all arranged in a tubular shape. The first filter screen 6, the second filter screen 7, and the third filter screen 8 are coaxially nested from the inside to the outside, and the filter pore size decreases layer by layer from the inside to the outside in the radial direction. The bottom of the first filter screen 6, the second filter screen 7, and the third filter screen 8 are all in tight contact with the top of the mounting plate 3.

[0026] A discharge pipe 9 is installed through and fixed on the mounting plate 3. The bottom of the discharge pipe 9 passes through the filter barrel 1 and extends outward. A valve 10 is installed on the discharge pipe 9.

[0027] As can be seen from the above, when filtration is required, the degreasing agent raw material to be filtered enters the feed pipe 4 through the connecting block 5. Since the outlet of the feed pipe 4 is close to the bottom of the cover plate 2, the liquid enters from the top of the filtration area and first fills the central cavity formed by the first filter screen 6, the second filter screen 7, and the third filter screen 8. The liquid flows naturally downward under the action of gravity, and the flow direction is parallel to the surface of the filter screen, rather than vertically impacting it, which reduces the possibility of the filter residue being directly pressed into the filter screen pores;

[0028] Meanwhile, the solid particles trapped by the filter screen are more likely to slide down the vertical inner wall of the filter screen under their own gravity and eventually settle in the bottom space of the filter tank 1, rather than forming a dense filter cake as on a flat filter screen. This significantly slows down the clogging speed of the filter screen surface and extends the effective filtration time.

[0029] Driven by pressure, the liquid passes through the first filter screen 6, the second filter screen 7, and the third filter screen 8 in sequence. These three filter screens are coaxially nested in a manner that decreases in pore size from the inside out, forming a highly efficient gradient filtration system that can remove impurities of different particle sizes step by step, ensuring the high cleanliness of the final filtered product.

[0030] The filtered clean liquid is collected in the bottom chamber of the filter tank 1. When it needs to be discharged, the valve 10 is opened and the liquid can flow out through the discharge pipe 9.

[0031] When filtration is complete and cleaning and maintenance are required, the operator simply pulls the locking block 11 outwards, causing it to compress the first spring 14 and disengage it from the slot of the cover plate 2, thus releasing the lock on the cover plate 2. This quick-locking component design simplifies opening the filter device and greatly facilitates subsequent cleaning of the entire filter mechanism integrated on the cover plate 2.

[0032] Specifically, regarding the aforementioned fixing components, the fixing components include a locking block 11 that is slidably disposed on the top of the filter bucket 1, and a slot adapted to the locking block 11 is opened on the top of the cover plate 2. The locking block 11 is inserted into the slot and is connected to an elastic component.

[0033] The elastic component includes multiple limiting rods 13 fixedly mounted on the outer wall of the locking block 11. A vertical plate 12 is fixedly mounted on the outer wall of the filter bucket 1. The ends of the multiple limiting rods 13 all penetrate the vertical plate 12 and are fixedly mounted with limiting blocks. A first spring 14 is sleeved on the outer wall of the limiting rods 13. The two ends of the first spring 14 are in close contact with the outer walls of the locking block 11 and the vertical plate 12, respectively.

[0034] As can be seen from the above, the fixing component achieves rapid locking and releasing of the cover plate 2 through the precise cooperation between the locking block 11 and the slot on the cover plate 2. When the cover plate 2 is placed in place, under the restoring force of the first spring 14, the locking block 11 is pushed to automatically and securely lock into the slot of the cover plate 2, ensuring that the filtration process is carried out in a closed environment.

[0035] The limiting rod 13 and its end limiting block work together to restrict the sliding stroke of the locking block 11, preventing it from moving excessively or completely disengaging, thus ensuring the reliability and safety of the mechanism's operation. This symmetrically arranged fixing component not only saves time and effort in operation, but more importantly, it provides uniform clamping force, ensuring the sealing performance between the cover plate 2 and the filter tank 1, as well as between the entire filter mechanism and the mounting plate 3, effectively preventing short-circuit leakage of unfiltered liquid.

[0036] Example 2:

[0037] The extrusion assembly includes an annular plate 15 fixedly disposed inside the filter barrel 1. The annular plate 15 is disposed inside the filter barrel 1 near the cover plate 2. Multiple extrusion rods 16 are slidably disposed through the outer wall of the annular plate 15. Each of the multiple extrusion rods 16 has a fixed block at its bottom.

[0038] A positioning block 17 is fixedly installed on the top of the extrusion rod 16, and a positioning groove adapted to the positioning block 17 is opened at the bottom of the cover plate 2, and the positioning block 17 is inserted into the positioning groove.

[0039] A second spring 18 is sleeved on the outer wall of the extrusion rod 16. The top and bottom of the second spring 18 are in close contact with the bottom of the positioning block 17 and the outer wall of the annular plate 15, respectively.

[0040] As can be seen from the above, when the filtration operation is completed, the operator pulls the locking block 11 outward to disengage it from the slot of the cover plate 2, and the locking of the cover plate 2 is released.

[0041] At this point, the second spring 18, which had previously stored elastic potential energy under compression, begins to release energy. The upper end of the second spring 18 acts on the positioning block 17, while the lower end acts on the fixed annular plate 15.

[0042] Since the positioning block 17 is tightly fitted into the positioning groove at the bottom of the cover plate 2, the restoring force of the second spring 18 will continuously and smoothly push the entire cover plate 2 upward through the positioning block 17 and the extrusion rod 16.

[0043] This allows the cover plate 2 and its integrated first filter 6, second filter 7, and third filter 8 to easily separate from their tight contact with the mounting plate 3 and rise slightly. This greatly facilitates the operator in subsequently grasping and completely removing the cover plate 2 for cleaning or replacement, making maintenance operations safer, less strenuous, and more efficient.

[0044] 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.
