Description

Technical Field

[0001] This utility model relates to a filter that is easy to clean of accumulated dust. Background Technology

[0002] Many industrial operations generate significant amounts of dust in the air, such as during polishing. This dusty air can negatively impact the health of operators, necessitating the use of filters. Modern filters typically employ a fan to draw in dusty air, then place a filter cartridge inside. The air passes through the cartridge, where the dust particles are adsorbed and collected. The filtered air is then expelled, effectively removing most of the dust. The filter cartridge is then maintained, cleaned, and reused. To minimize filter cartridge maintenance, many filters incorporate... A pulse valve is installed at the top of the filter cartridge. Opening the pulse valve allows for pressurized air blowing, blowing most of the dust off the cartridge and causing it to fall to the bottom. A dust bag is then placed at the bottom, connected directly to the bottom of the filter via a connector. This prevents dust from scattering when it enters the dust bag. However, many dust bags are made of high-density cloth for washing and reuse. Even the highest density cloth bags cannot provide an efficient seal without a metal trolley or frame for sealing. Furthermore, the dust bag is quite heavy when full of dust, making it inconvenient to handle, and the small opening hinders subsequent dust discharge. Utility Model Content

[0003] The present invention aims to solve the technical problems existing in the prior art, thereby providing a filter that is easy to clean and convenient to use.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0005] This utility model discloses an easy-to-clean filter, comprising a main unit, a fan box located at the top of the main unit, and a dust collection device located at the bottom of the main unit; the main unit and the fan box are in a connected state; the main unit and the dust collection device are also in a connected structure; the dust collection device includes a dust inlet and a dust hopper; the dust hopper is a pull-out trolley with casters at the bottom and rollers on both sides for pulling and sliding the dust hopper.

[0006] Preferably, a U-shaped plate is fixedly provided at the bottom of the ash inlet; the U-shaped plate includes a horizontal plate and vertical plates perpendicular to both sides of the horizontal plate, and an inwardly extending support guide is provided at the end of the vertical plate.

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0025] like Figure 1 , 6 As shown in Figure 9, an easy-to-clean dust filter is mainly used for dust filtration. It draws in dust-laden air via a fan, filters it, and then discharges it. The filter includes a main unit housing 2, a fan housing 1 located at the top of the main unit housing 2, and a dust collection device 3 located at the bottom of the main unit housing 2. The main unit housing 2 and the fan housing 1 are connected; the main unit housing 2 and the dust collection device 3 are also connected.

[0026] The ash collection device 3 includes an ash inlet 9 and an ash hopper 3.1. The ash hopper 3.1 is a pull-out trolley with casters at the bottom and rollers 3.3 on both sides for sliding. A U-shaped plate is fixedly installed at the bottom of the ash inlet 9. The U-shaped plate includes a horizontal plate 3.22 and vertical plates 3.23 perpendicular to both sides of the horizontal plate 3.22. An inwardly extending support guide 3.21 is provided at the end of the vertical plate 3.23. Specifically, when the ash hopper 3.1 is in the ash collection working state, the rollers 3.3 are located on the support guide 3.21. The support guide 3.21 is also the guide rail for the rollers 3.3. When the ash hopper 3.1 needs to be cleaned, it can be pulled away from the support guide 3.21, so that the ash hopper 3.1 can be pulled out as a whole for cleaning and maintenance.

[0027] The ash inlet 9 has a bucket-shaped structure that is larger at the top and smaller at the bottom, and the ash inlet 9 and the horizontal plate 3.22 are connected. Specifically, a through hole is provided at the position where the horizontal plate 3.22 contacts the ash inlet 9 so that dust can fall into the ash hopper 3.1 through the ash inlet 9.

[0028] See Figure 10 As shown, the top of the fan box 1 is provided with multiple air outlets 1.1, allowing filtered air to be discharged from the air outlets 1.1; the bottom is also provided with a through hole (not labeled) that communicates with the main unit box 2.

[0029] See Figure 2-5 As shown, a fixing plate 10 is provided inside the main unit housing 2 near the upper end of the fan housing 1; specifically, the fixing plate 10 is fixed to the inner side wall of the main unit housing 2.

[0030] The fixing plate 10 has four symmetrical air outlets 10.1. Below each air outlet 10.1 is a retaining ring 10.2. Multiple retaining strips 10.3 are evenly arranged on the inner side of the retaining ring 10.2. In other words, this is the connection method between many lids and cups. Several protruding retaining strips are set at intervals on the inner wall of the lid or cup, and corresponding retaining points are set on the other side. When the retaining strips touch the retaining points, they can be fixed. Opening and fixing can be achieved by simply rotating one of the parts.

[0031] Four detachable filter cartridges 8 are respectively provided below the air outlet 10.1; more specifically, the filter cartridges 8 are fixed to the bottom of the fixing plate 10 by rotating the buckle strip 10.3. When the filter cartridges 8 need to be replaced or maintained, they can be removed from the fixing plate 10 simply by rotating the filter cartridges 8.

[0032] A pulse valve through-pipe 7.1 is provided at the upper center of the fixed plate 10, and four pulse valves 7 are symmetrically arranged on both sides of the pulse valve through-pipe 7.1. Specifically, the four pulse valves 7 correspond to four air outlets 10.1. When the filter stops working, the pulse valves 7 are opened to blow air through the air outlets 10.1 to the filter cartridge 8. This blows away the dust on the filter cartridge 8 and allows the dust to enter the ash hopper 3.1. Although the air blowing of the pulse valves 7 to the filter cartridge 8 cannot ensure that all the dust on the filter cartridge 8 is cleaned, it can clean away most of the dust, ensuring that the filter cartridge 8 can be repeatedly operated before it needs to be disassembled for maintenance, rather than needing to be disassembled for maintenance after each operation. Since the working principle of the pulse valve to the filter cartridge is existing technology, the applicant will not describe it in detail here.

[0033] The main unit 2 has an openable filter cartridge inspection port 2.1 on one side; an air inlet 5 is provided on the other side, and an inspection port 6 is provided above the air inlet 5 corresponding to the position of the pulse valve 7 for inspecting the pulse valve 7.

[0034] A baffle plate 5.1 is installed on the inner side wall of the main unit 2 at the position corresponding to the air inlet 5 to buffer the air entering through the air inlet from directly hitting the filter cartridge 8, so as to avoid a large amount of air blowing directly and damaging the filter cartridge 8. Specifically, the air inlet 5 corresponds to the filter cartridge 8, so the air entering from the air inlet will be directly filtered through the filter cartridge 8 and then drawn upward by the fan and discharged from the air outlet 1.1.

[0035] The fan box 1 is equipped with a fan (not shown), and the noise of the fan can be reduced by filling the inner wall of the fan box 1 with sound insulation cotton. This is prior art, and the applicant will not describe it in detail.

[0036] The beneficial effects of this utility model are:

[0037] This application designs the dust collection section below the filter as a small, fully sliding dust hopper. There are horizontal and vertical plates between the dust hopper and the dust inlet. This design reduces the gaps in the dust hopper while allowing it to be pushed and pulled, preventing dust from dispersing into the air during the dust hopper process. The fully sliding dust hopper makes the dust hopper very convenient for later cleaning and maintenance. In addition, this small dust hopper is more durable and has better sealing performance than bagged dust hoppers.
