Description

Technical Field

[0001] This application relates to the field of fluid filtration device technology, and in particular to a self-ignition-proof drawer-type filter box. Background Technology

[0002] A filter box is a device for filtering harmful substances from fluids. Fluid is passed into the filter box and flows through adsorption elements within it. These elements adsorb the harmful substances to achieve a filtration effect. However, the adsorption elements need to be stacked to ensure effective adsorption. During the adsorption of harmful substances, the fluid continuously passes through the elements, converting its kinetic energy into heat. Since heat dissipation is difficult for the adsorption elements, the temperature in some areas will continuously rise. When the temperature of these areas approaches the ignition point, combustion may occur, posing a safety hazard. Utility Model Content

[0003] The purpose of this application is to provide a self-ignition-proof drawer-type filter box, which aims to improve the heat dissipation difficulties of filter boxes in related technologies that easily lead to combustion problems, and to improve the safety and stability of the filter box.

[0004] This application provides a self-ignition-proof drawer-type filter box, including a support structure, a filter structure, a flow guiding structure, and a spray structure disposed on the support structure; the support structure includes a support bracket with several air passages; the filter structure includes several filter elements disposed between the air passages; the flow guiding structure includes several baffles disposed in the air passages, the baffles and the filter elements forming a filter channel; the spray structure includes a spray pipe disposed on the support bracket and several spray heads disposed on the spray pipe, the spray heads facing the filter elements.

[0005] Furthermore, the spray structure also includes a spray tank disposed on the support bracket and a discharge pipe connected to the spray tank, the spray tank being located below the plurality of filter elements.

[0006] Furthermore, there are three air passages: an upper air passage, a middle air passage, and a lower air passage; and there are three baffles: an upper baffle in the upper air passage, a middle baffle in the middle air passage, and a lower baffle in the lower air passage.

[0007] Furthermore, the airflow guiding structure also includes a guide plate, which is disposed in the upper air duct and the lower air duct, and the guide plate is configured with a rounded transition.

[0008] Furthermore, the support structure also includes a drawer cabinet disposed on the support bracket, the drawer cabinet being slidably connected to the support bracket, and the filter element being disposed inside the drawer cabinet.

[0009] Furthermore, the drawer cabinet is provided with a guide plate, and the guide plate has several guide holes for fluid to pass through.

[0010] Furthermore, it also includes a detection structure, which includes a temperature detector disposed on the support bracket.

[0011] The beneficial effects of this application are:

[0012] 1. The present application discloses a self-ignition-proof drawer-type filter box, which, by setting a filter structure, a flow guiding structure, and a spray structure in the support structure, can effectively increase the movement distance of the fluid in the filter box under the action of the flow guiding structure, thereby increasing the contact time with the filter element and improving the filtration effect of the fluid; at the same time, the spray structure, by setting several spray heads facing the filter element in the spray pipe, can spray coolant onto the filter element in time when the temperature of the filter element rises, thereby dissipating heat and cooling the filter element, preventing the filter element from igniting due to continuous temperature rise, and improving the safety and stability of the filter box.

[0013] 2. The present application discloses a self-ignition-proof drawer-type filter box, which houses the filter element by setting a drawer cabinet in the support bracket. The filter element is supported in the drawer cabinet, and the drawer cabinet is provided with a guide plate to allow fluid to pass through. When installing or replacing the filter element, the drawer cabinet can be pulled out for convenient operation. At the same time, corresponding baffles and guide plates are set in the three air passages. By using the baffles and guide plates to block and guide the fluid, the fluid can move along two predetermined paths, thereby ensuring that the fluid can pass through the filter element multiple times for filtration.

[0014] 3. The present application discloses a self-ignition-proof drawer-type filter box. The spray structure is provided with a spray tank and a discharge pipe connected to the spray tank. With the help of a temperature detector in the detection structure, when the temperature detector detects that the temperature has reached a preset value, the spray head sprays coolant onto the filter element to cool it down. The coolant falls into the spray tank after passing through the filter element and is discharged automatically through the discharge pipe, preventing the coolant from flowing to the ground. This eliminates the need for cleaning and increases the ease of use of the filter box. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0024] Reference Figure 1 as well as Figure 2 This application provides a self-ignition-proof drawer-type filter box, including a support structure 1, a filter structure 2 disposed on the support structure 1, a flow guiding structure 3, and a spray structure 4. During operation, the flow guiding structure 3 forms a filtration channel inside the filter box. Fluid enters the filter box and is filtered through the filter structure 2. When the temperature of the filter structure 2 reaches a preset temperature, the spray structure 4 sprays coolant onto the filter structure 2 to cool it down and prevent combustion due to excessive temperature.

[0025] Specifically, the support structure 1 is used to support the filter structure 2, the flow guiding structure 3, and the spray structure 4. The support structure 1 includes a support bracket 11, which has several air passages 111. In this embodiment, there are three air passages 111: an upper air passage, a middle air passage, and a lower air passage. The upper air passage, the middle air passage, and the lower air passage are parallel to each other and evenly arranged along the height direction of the support bracket 11. At the same time, the support bracket 11 has an air inlet 112 and an air outlet 113. The air inlet 112 is located at one end of the length direction of the support bracket 11, and the air outlet 113 is located at the other end of the length direction of the support bracket 11. Fluid will enter from the air inlet 112, pass through the filter structure 2 and the flow guiding structure 3, and then be discharged from the air outlet 113.

[0026] To support the filter structure 2, the support structure 1 also includes a drawer cabinet 12 mounted on the support bracket 11. The drawer cabinet 12 is slidably connected to the support bracket 11. The filter structure 2 is housed within the drawer cabinet 12, and can be pushed in or pulled out by pushing and pulling the drawer cabinet 12, thus enabling the installation or replacement of the filter structure 2. To facilitate fluid flow, the drawer cabinet 12 is equipped with a guide plate 13 located on the upper and lower sides of the drawer cabinet 12. The guide plate 13 has several through holes 131 for fluid to pass through. During filtration, the fluid enters from the guide plate 13 on one side of the drawer cabinet 12, passes through the filter structure 2, and then flows out from the guide plate 13 on the other side of the drawer cabinet 12.

[0027] The filter structure 2 includes several filter elements disposed between the air passages 111. In this embodiment, the filter element is activated carbon, and the filter element is disposed inside the drawer cabinet 12. It is understood that the filter element can be selected according to the usage scenario; the filter element can be diatomaceous earth, or it can be an adsorbent, etc.

[0028] The airflow guiding structure 3 includes several baffles 31 disposed in the air passage 111, and the baffles 31 and the filter elements surround each other to form a filter channel. In this embodiment, there are three baffles 31, namely an upper baffle disposed in the upper air passage, a middle baffle disposed in the middle air passage, and a lower baffle disposed in the lower air passage. Each baffle is vertically disposed, with the upper baffle located on the side of the upper air passage near the air outlet 113, the middle baffle located on the side of the middle air passage near the air inlet 112, and the lower baffle located on the side of the lower air passage near the air outlet 113.

[0029] By setting the baffle plate 31 in this way, the support bracket 11 is divided into upper and lower filtration channels under the action of the baffle plate 31. The two filtration channels are symmetrically arranged, and the fluid entering the filter box passes through multiple filter elements in sequence after entering the filtration channel. In addition, the flow guiding structure 3 also includes a flow guide plate 32, which is set in the upper air duct and the lower air duct. In this embodiment, there are two flow guide plates 32, which are located on the side of the upper air duct and the lower air duct near the air inlet 112, respectively. The flow guide plates 32 are set with an arc transition. By setting the flow guide plate 32, the fluid entering from the air inlet 112 can pass through the filtration channel more smoothly under the guidance of the flow guide plate 32, avoiding airflow and turbulence.

[0030] The spray structure 4 includes a spray pipe 41 mounted on a support bracket 11 and a plurality of spray heads 42 mounted on the spray pipe 41, with the spray heads 42 facing the filter elements. The spray pipe 41 is located above the support bracket 11, and the spray heads 42 are arranged along the length of the spray pipe 41 and evenly distributed above the filter elements. When the temperature of the filter elements is too high, or when a preset time period is reached, the spray heads 42 spray coolant onto the filter elements, effectively dissipating heat and lowering the filter elements under the action of the coolant. In addition, the spray structure 4 also includes a spray tank 43 mounted on the support bracket 11 and a discharge pipe 44 connected to the spray tank 43. The spray tank 43 is located below the filter elements. After the coolant dissipates heat and lowers the temperature of the filter elements, it falls into the spray tank 43 for collection and is then discharged from the discharge pipe 44.

[0031] Reference Figure 3 as well as Figure 4 In order to cooperate with the spray structure 4, the filter box also includes a detection structure 5. The detection structure 5 includes a temperature detector 51 installed on the support bracket 11. In this embodiment, the temperature detector 51 is located above the support bracket 11. The temperature detector 51 can detect the temperature in the filter box in a timely manner. When the temperature of the filter element rises, the temperature in the filter box rises accordingly. When the temperature reaches the preset value, the temperature detector 51 issues an alarm or directly drives the spray structure 4 to operate, thereby preventing the filter box from burning and increasing the safety and operational stability of the filter box.

[0032] Exemplary embodiments of this disclosure have been specifically shown and described above. It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
