Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology and discloses a filter box that is easy to clean. Background Technology

[0002] In the current process of rapid industrialization, various production activities inevitably generate gases containing dust, harmful particulate matter, and other pollutants. If these gases are directly released into the air, they will cause serious damage to the ecological environment and also endanger human health. Therefore, the effective filtration and treatment of industrial waste gases and other pollutants has become an important issue in the field of environmental protection.

[0003] Traditional filtration equipment has significant drawbacks in terms of cleaning and maintenance: the filter elements of most filtration equipment have complex installation structures and cumbersome disassembly processes, requiring specialized tools and technicians. This not only increases maintenance costs but also affects production progress due to excessive downtime. In addition, traditional filter elements are mostly flat, with limited filtration area, which can easily lead to insufficient filtration when processing large flow rates of gas, and the gas flow resistance is relatively high, affecting filtration efficiency.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a filter box that is easy to clean, solving the problems of inconvenience in cleaning the filter screen and limited filtration area in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easy-to-clean filter box, comprising:

[0008] The filter housing is hollow inside and forms a first chamber and a second chamber. An air inlet pipe and an air outlet pipe are connected to the upper end of the filter housing. Several windows are opened on the rear surface of the filter housing, and a sealing plate is provided inside the windows.

[0009] A partition plate is located between the first chamber and the second chamber, and the filter box is fixedly connected to the upper end and both ends of the partition plate.

[0010] A support assembly, wherein there are two support assemblies stacked one on top of the other, and the support assemblies are located inside the first cavity;

[0011] A filter screen cover is disposed on the upper end of the support assembly, and the filter screen cover has a convex structure.

[0012] A fixing component, wherein there are multiple fixing components and they are disposed on both sides of the upper end of each of the sealing plates.

[0013] Furthermore, the bottom end of the intake pipe is connected to the first chamber, and the bottom end of the exhaust pipe is connected to the second chamber.

[0014] Furthermore, the support assembly includes three equally spaced fixing plates, which are fixedly connected to the filter box, and the right end of the right fixing plate is fixedly connected to the isolation plate.

[0015] Furthermore, a support frame is fixedly connected between each of the two adjacent fixed plates on the left and right sides, and the filter screen corresponds one-to-one with the support frame and is placed on the upper end of the support frame.

[0016] Furthermore, the sealing plate is provided with a hinge on its surface, and the two flaps of the hinge are respectively fixedly connected to the sealing plate and the filter box.

[0017] Furthermore, the fixing component includes:

[0018] A first mounting plate and a second mounting plate are respectively fixedly connected to the sealing plate and the filter box;

[0019] A limiting buckle is fixedly connected to the front end of the second mounting plate;

[0020] A lever is rotatably connected to the front end of the first mounting plate and a limit rod is fixedly connected to its upper surface.

[0021] Furthermore, the limiting rod is used in conjunction with the limiting buckle and can be inserted into the limiting buckle.

[0022] Furthermore, several evenly distributed support feet are fixedly connected to the bottom surface of the filter box.

[0023] This utility model provides a filter box that is easy to clean, and has the following beneficial effects:

[0024] (1) This utility model achieves rapid opening and closing of the sealing plate by setting a hinged sealing plate at the rear end of the filter box and cooperating with a fixing component consisting of limit buckles, levers, etc. When the filter screen needs to be cleaned, simply operate the fixing component to loosen the sealing plate, and the filter screen placed on the support frame can be directly removed through the window without disassembling the complex structure, which greatly simplifies the cleaning process, reduces maintenance difficulty and cost, and avoids the impact of frequent disassembly on the overall sealing performance of the equipment, thus ensuring the stability of the filtration process.

[0025] (2) This utility model, through its convex filter screen design, significantly increases the filtration area within the limited space of the first chamber, thereby improving the interception efficiency of pollutants in the gas. Simultaneously, the raised structure guides the gas to flow more evenly across the filter screen surface, reducing local airflow resistance and enhancing the smoothness of gas flow. Furthermore, the support assembly, through the mounting plate and support frame, forms a stable support, making the filter screen less prone to deformation under gas impact, extending its service life, and balancing high-efficiency filtration with structural durability.

Detailed Implementation

[0034] 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.

[0035] Please see Figure 1-6 A filter box that is easy to clean includes: a filter box body 1, which is hollow inside and forms a first chamber and a second chamber; an air inlet pipe 101 and an exhaust pipe 102 are connected to the upper end of the filter box body 1; the air inlet pipe 101 is used to connect to an external sewage pipe to introduce the gas to be filtered into the filter box body 1; a plurality of windows 104 are opened on the rear surface of the filter box body 1; a sealing plate 105 is provided inside the window 104; a rubber sealing gasket is provided on the edge of the sealing plate 105 to enhance airtightness; a plurality of evenly distributed support feet 103 are fixedly connected to the bottom surface of the filter box body 1 to support the filter box body 1; and an isolation plate 2 located in the first chamber and the second chamber. Between the chambers, the upper end and both ends of the isolation plate 2 are fixedly connected to the filter box 1, forming an independent gas channel through the internal isolation plate 2. The first chamber serves as the air intake filtration area, and the second chamber serves as the purified gas storage area, realizing the zoned control of the filtration process; there are two support components 3, which are stacked one on top of the other. The support components 3 are located inside the first chamber, and the window 104 corresponds to the position of the support components 3; the filter screen 4 is set on the upper end of the support components 3 and has a convex structure; there are multiple fixing components 5, which are set on both sides of the upper end of each sealing plate 105 to fix the sealing plate 105.

[0036] Specifically, the bottom end of the intake pipe 101 is connected to the first chamber, and the bottom end of the exhaust pipe 102 is connected to the second chamber.

[0037] Through the above technical solution, the air inlet pipe 101 is connected to the first chamber and the exhaust pipe 102 is connected to the second chamber. Combined with the isolation plate 2, it is ensured that the gas must be filtered before it can be discharged, avoiding short circuits and improving purification efficiency.

[0038] Specifically, the support assembly 3 includes three equally spaced fixing plates 301, which are fixedly connected to the filter housing 1. The right end of the right fixing plate 301 is fixedly connected to the isolation plate 2. A support frame 302 is fixedly connected between each pair of adjacent fixing plates 301. The filter screen 4 corresponds to the support frame 302 and is placed on the upper end of the support frame 302. The filter screen 4 can slide back and forth on the surface of the support frame 302, and the height of the support frame 302 is flush with the window 104, making it easy to remove the filter screen 4 from the window 104.

[0039] Through the above technical solution, the support component 3 provides stable multi-layer installation support for the filter screen 4, ensuring that it is not easily displaced during the filtration process, and also realizes the convenient removal and placement of the filter screen 4, which meets the core requirement of easy cleaning of the filter box. At the same time, the overall filtration efficiency is improved through multi-layer filtration.

[0040] Specifically, the sealing plate 105 has a hinge 106 on its surface. The two flaps of the hinge 106 are fixedly connected to the sealing plate 105 and the filter box 1, respectively. The sealing plate 105 can be opened and closed through the hinge 106. The fixing assembly 5 includes: a first mounting plate 501 and a second mounting plate 502, which are fixedly connected to the sealing plate 105 and the filter box 1, respectively; a limit buckle 503, which is fixedly connected to the front end of the second mounting plate 502; and a lever 504, which is rotatably connected to the front end of the first mounting plate 501 and has a limit rod 505 fixedly connected to its upper surface. The limit rod 505 works in conjunction with the limit buckle 503 and can be inserted into the limit buckle 503. When the lever 504 is pushed upward, the limiting rod 505 will be inserted into the limiting buckle 503, thus preventing the sealing plate 105 from opening. When the lever 504 is pushed downward, the limiting rod 505 will disengage from the limiting buckle 503, at which point the sealing plate 105 can be opened.

[0041] The above technical solution ensures that the sealing plate 105 can be tightly closed during filtration, ensuring the airtightness of the filter box 1 to avoid gas leakage affecting the filtration effect. It also allows the sealing plate 105 to be quickly released and opened by moving the lever 504, providing convenient operation for taking the filter screen 4 out of the window 104 for cleaning. At the same time, it simplifies the opening and closing operation of the sealing plate 105 and improves the efficiency of equipment maintenance.

[0042] In use, the gas to be filtered enters the first chamber of the filter box 1 through the air inlet pipe 101, passes through the filter screen 4 on the multi-layer support assembly 3 to complete the filtration, and then enters the second chamber through the space above the isolation plate 2, and finally is discharged from the exhaust pipe 102. When cleaning is required, operate the lever 504 of the fixing assembly 5 to disengage the limit rod 505 from the limit buckle 503, open the sealing plate 105 through the hinge 106, take out the filter screen 4 from the window 104 for cleaning, put it back into the support assembly 3 after cleaning, close the sealing plate 105 and fix it with the fixing assembly 5.
