Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a drawer-type filter. Background Technology

[0002] Drawer-type filters are filtration devices that use a removable filter element carrier for filtration and maintenance. They are widely used in air purification, liquid treatment, dust collection and other scenarios. Their core feature is that the filter element carrier can be pulled out or pushed in from the main body of the device like a drawer. The filter media can be replaced, cleaned or repaired without disassembling the entire device, which can effectively simplify the maintenance process and shorten downtime.

[0003] The middle filter screen of a traditional clip-on filter cannot be removed and replaced separately. Over time, this can lead to excessive dirt buildup on the filter screen surface, affecting its subsequent use.

[0004] An existing patent (publication number: CN218357686U) discloses a drawer-type filter, including a front plate and a rear plate. A discharge port is provided in the middle of the surface of the front and rear plates. A slot is provided on the inner surface of the front and rear plates. A discharge port is provided at the bottom of the surface of the rear plate. A positioning pin is fixedly connected to the rear surface of the front plate. This drawer-type filter, through the coordinated arrangement of the front plate, rear plate, discharge port, slot, discharge port, positioning pin, positioning socket, honeycomb steel frame, filter screen, and stepped positions, allows for the separate removal and replacement of the middle filter screen compared to traditional clamp-type filters. The slot design in the filter screen placement structure prevents it from falling off or becoming misaligned after installation. The positioning pin and positioning socket in the front and rear plates and the upper and lower structures provide better positioning. The stepped positions in the middle honeycomb steel frame are used for the convergence of filtered materials. The discharge port is designed for emptying after filter screen replacement or for sampling during the process.

[0005] To address the aforementioned issues, existing patents offer solutions. However, most existing drawer-type filters lack an effective structure to receive the media carried out of the drawer during use, causing the media to easily flow and drip on the front side of the filter body, polluting the filtration environment. This not only increases environmental cleanup costs but may also shorten the equipment's lifespan due to media corrosion of surrounding components.

[0006] Therefore, a drawer-type filter is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a drawer-type filter that can solve the problem that most existing drawer-type filters lack an effective receiving structure for the medium carried out of the drawer during use, which makes the medium easy to flow and drip on the front side of the filter body, polluting the filtration site environment. This not only increases the environmental cleaning cost, but may also shorten the service life of the equipment due to the corrosion of surrounding parts by the medium.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a drawer-type filter, comprising a filter body, a liquid guiding mechanism fixedly connected to the front side of the filter body, a flip-up collection rack provided on the front side of the filter body, a positioning block provided at the bottom of the flip-up collection rack, the rear side of the positioning block contacting the front side of the filter body, the liquid guiding mechanism comprising a liquid collection rack, a flow guide rack fixedly connected to the surface of the liquid collection rack, and a flow guide pipe movably connected to the bottom of the flow guide rack.

[0009] Preferably, the surface of the flow guide is fixedly connected to the inner wall of the filter body, and the rear side of the liquid collection rack is fixedly connected to the front side of the filter body.

[0010] Preferably, the inner wall of the flow guide frame is provided with a liquid inlet groove for use with the liquid collection frame, and the inner wall of the flow guide frame is provided with a flow guide groove.

[0011] Preferably, the inner wall of the filter body is provided with a fixing groove for use with the liquid collection rack, and the inner wall of the liquid collection rack is provided with a liquid collection tank.

[0012] Preferably, a connecting block is fixedly connected to the front side of the filter body, and a rotating block is fixedly connected to the front side of the connecting block.

[0013] Preferably, the inner wall of the rotating block is rotatably connected to a rotating shaft, and the rotating shaft is fixedly connected to the rotating collection rack on the side near the rotating collection rack.

[0014] Preferably, the bottom of the flip-over collection rack is movably connected to a drainage assembly, and a limit rod is fixedly connected to the right side of the flip-over collection rack.

[0015] Preferably, a connecting frame is fixedly connected to the front side of the positioning block, and the top of the connecting frame is fixedly connected to the bottom of the flipping collection frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By setting up a liquid guiding mechanism, this application can receive water and other media brought out by the drawer when the filter body is maintained or the drawer is pulled out, to prevent the media from flowing randomly on the front side of the filter body and effectively prevent the on-site filtration environment from being contaminated. At the same time, the guide frame can guide the received media, so that the media can be stably discharged through the guide pipe to the designated collection container, which not only avoids corrosion around the equipment caused by media residue, but also reduces the workload of subsequent environmental cleaning, ensuring the cleanliness and safety of the filtration site.

[0018] 2. This application, by setting up a flip-over collection rack, can be unfolded during the overall maintenance of the filter body to receive the medium, further improving the integrity of medium collection and preventing medium leakage during the drawer pull-out process. The positioning block can provide stable support and positioning for the unfolded flip-over collection rack, preventing the flip-over collection rack from shifting due to the weight of the medium or external force during liquid collection, ensuring stable liquid collection. Furthermore, when not in use, the flip-over collection rack can be folded up, without occupying too much operating space, thus improving the flexibility of the filter body.

Detailed Implementation

[0027] 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.

[0028] Please see Figure 1-7 The present invention provides the following technical solution:

[0029] A drawer-type filter includes a filter body 1. A liquid guiding mechanism 2 is fixedly connected to the front side of the filter body 1. A flip-up collection rack 3 is provided on the front side of the filter body 1. A positioning block 4 is provided at the bottom of the flip-up collection rack 3. The rear side of the positioning block 4 contacts the front side of the filter body 1. The liquid guiding mechanism 2 includes a liquid collection rack 201. A flow guide rack 202 is fixedly connected to the surface of the liquid collection rack 201. A flow guide pipe 203 is movably connected to the bottom of the flow guide rack 202.

[0030] In this embodiment: By setting up the liquid guiding mechanism 2, the water and other media brought out by the drawer can be received during the maintenance of the filter body 1 and the moment the drawer is pulled out, preventing the media from flowing randomly on the front side of the filter body 1 and effectively preventing the on-site filtration environment from being contaminated. At the same time, the flow guide 202 can guide the received media, so that the media can be stably discharged to the designated collection container through the flow guide pipe 203. This not only avoids corrosion around the equipment caused by media residue, but also reduces the workload of subsequent environmental cleaning, ensuring the cleanliness and safety of the filtration site. By setting up the flip collection rack 3, it can be unfolded during the overall maintenance of the filter body 1 to receive the media, further improving the integrity of media collection and preventing media leakage during the drawer being pulled out. The positioning block 4 can provide stable support and positioning for the unfolded flip collection rack 3, preventing the flip collection rack 3 from being displaced due to the weight of the media or external force during the liquid collection process, ensuring stable liquid collection. Furthermore, when not in use, the flip collection rack 3 can be folded up, without occupying too much operating space, improving the flexibility of the use of the filter body 1.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, the surface of the flow guide 202 is fixedly connected to the inner wall of the filter body 1, and the rear side of the liquid collection rack 201 is fixedly connected to the front side of the filter body 1.

[0032] Specifically, such as Figure 4 As shown, the inner wall of the flow guide 202 is provided with a liquid inlet groove 5 that works in conjunction with the liquid collection rack 201, and the inner wall of the flow guide 202 is provided with a flow guide groove 6.

[0033] Specifically, such as Figure 3 , Figure 7 As shown, the inner wall of the filter body 1 is provided with a fixing groove 7 that works in conjunction with the liquid collection rack 201, and the inner wall of the liquid collection rack 201 is provided with a liquid collection tank 8.

[0034] In this embodiment: the guide frame 202 is fixed to the position of the filter body 1, and the liquid collection frame 201 is fixed to the front side of the filter body 1, which can ensure the stability of the medium receiving. The liquid inlet groove 5 on the inner wall of the guide frame 202 allows the medium collected by the liquid collection frame 201 to flow into the guide frame 202. In conjunction with the guide groove 6, the medium is guided in a directional manner, preventing the medium from stagnating and accumulating in the guide frame 202. The fixing groove 7 on the inner wall of the filter body 1 provides installation positioning for the liquid collection frame 201, ensuring that the liquid collection frame 201 fits tightly with the filter body 1. The liquid collection groove 8 on the inner wall of the liquid collection frame 201 can expand the medium receiving capacity, prevent the medium from overflowing, and further improve the medium collection efficiency of the liquid guiding mechanism 2.

[0035] Specifically, such as Figure 6 As shown, a connecting block 9 is fixedly connected to the front side of the filter body 1, and a rotating block 10 is fixedly connected to the front side of the connecting block 9.

[0036] Specifically, such as Figure 6 As shown, a rotating shaft 11 is rotatably connected to the inner wall of the rotating block 10, and the rotating shaft 11 is fixedly connected to the rotating collection rack 3 on the side near the rotating collection rack 3.

[0037] In this embodiment: by setting the connecting block 9 and the rotating block 10, the position of the rotating block 10 and the connecting block 9 is fixed during use, and the position of the rotating shaft 11 and the flip collection rack 3 is fixed, which makes it easy for the flip collection rack 3 to rotate flexibly around the rotating shaft 11. This makes it easy to quickly unfold the flip collection rack 3 for media collection during maintenance, and it can be easily folded and stored when not in use, reducing operation steps and improving the ease of use of the flip collection rack 3.

[0038] Specifically, such as Figure 5 As shown, the bottom of the flip collection rack 3 is movably connected to the drainage component 12, and the right side of the flip collection rack 3 is fixedly connected to the limit rod 13.

[0039] Specifically, such as Figure 6 As shown, a connecting frame 14 is fixedly connected to the front side of the positioning block 4, and the top of the connecting frame 14 is fixedly connected to the bottom of the flipping collection rack 3.

[0040] In this embodiment: by setting the drainage component 12 and the limiting rod 13, the collected medium can be discharged to the designated container in a timely manner, avoiding the medium from being retained in the flip collection rack 3 for a long time, which may lead to deterioration or corrosion of the parts. The limiting rod 13 can cooperate with the surrounding structure to form a limit when it is folded, preventing the flip collection rack 3 from flipping randomly when folded. By setting the connecting frame 14, the supporting force of the positioning block 4 on the flip collection rack 3 can be evenly transmitted, avoiding the deformation of the flip collection rack 3 due to uneven force, and further enhancing the structural stability of the flip collection rack 3 after it is unfolded.

[0041] Working principle: During the maintenance of the filter body 1, the flip collection rack 3 rotates on the inner wall of the rotating block 10 via the rotating shaft 11, which facilitates the flip collection rack 3 to enter the collection state. The positioning block 4 at the bottom of the flip collection rack 3 can ensure the stability of the flip collection rack 3 during collection. Then, the drawer is pulled out for maintenance. The medium brought out at the moment the top drawer is pulled out first falls into the liquid collection rack 201. The liquid collection groove 8 on the inner wall of the liquid collection rack 201 expands the receiving capacity. The medium then flows into the guide rack 202 through the liquid inlet groove 5 on the inner wall of the guide rack 202. After being guided by the guide groove 6, it is discharged from the guide pipe 203 to the designated container. During the maintenance, the flip collection rack 3 receives the remaining medium. The drainage component 12 at the bottom discharges the collected medium in time to avoid retention and deterioration. After the maintenance is completed, the flip collection rack 3 is folded around the rotating shaft 11, and the limit rod 13 cooperates with the limit to complete the maintenance operation.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
