Description

Technical Field

[0001] This utility model relates to the field of filter tank technology, and in particular to a separation device for a multi-media filter tank operating under negative pressure. Background Technology

[0002] Multi-media filters utilize one or more filter media and are suitable for water treatment such as turbidity removal, water softening, and pretreatment of pure water. For example, the S-GL-100 multi-media filter tank removes impurities from the water and clarifies it when external water enters the tank and is pressurized and sprayed through a water distribution plate. The water passes through a certain thickness of granular or non-granular material (such as quartz sand, anthracite, manganese sand, etc.).

[0003] In the prior art, for example, Chinese Patent No. CN215654055U discloses a separation device for a high-efficiency multi-media filter tank, including a filter tank body, an inlet pipe on the filter tank body, a control valve on the inlet pipe, an external inlet pipe on the front side of the control valve, a filter pipe between the control valve and the external inlet pipe, and a separation mechanism including an annular support, a filter screen fixedly connected to the inner ring of the annular support, a connecting groove on the inner wall of the filter pipe, and a buffer component fixedly connected between the outer ring of the annular support and the inner wall of the connecting groove. This separation device for a high-efficiency multi-media filter tank, by incorporating a separation mechanism, avoids clogging of the water distribution tray, ensuring the effectiveness of the water distribution tray, and also reduces the accumulation of excessive impurities in the filter tank during the filtration process, reducing the frequency of cleaning impurities inside the filter tank and reducing the workload of operators.

[0004] While the above-mentioned solution has the advantages mentioned above, it also has disadvantages. Although the separation mechanism can prevent clogging of the water distribution pan and ensure its effectiveness, it also reduces the accumulation of impurities in the filter tank during filtration, decreases the frequency of cleaning, reduces the workload of staff, and increases the lifespan of the filter media, thus ensuring the overall effectiveness of the filter tank. However, impurities filtered by the filter screen will remain in the filter tube, requiring disassembly and cleaning. Due to the relatively small diameter of the filter tube, impurities filtered by the filter screen can easily clog it, affecting the water flow rate and necessitating frequent disassembly and cleaning. This ultimately reduces the filtration efficiency of the multi-media filter tank. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that, although it can avoid clogging of the water distribution plate by setting a separation mechanism, thus ensuring the effectiveness of the water distribution plate, and also reducing the accumulation of excessive impurities in the filter tank during the filtration process, reducing the frequency of cleaning the impurities inside the filter tank, reducing the workload of the workers, increasing the service life of the filter media in the filter tank, and ensuring the effectiveness of the filter tank, the impurities filtered by the filter screen will remain in the filter tube, requiring the filter tube to be disassembled and cleaned. Because the diameter of the filter tube is relatively small, the impurities filtered by the filter screen can easily clog the filter tube, affecting the water flow rate, requiring frequent disassembly and cleaning of the filter tube, thus reducing the filtration efficiency of the multi-media filter tank.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a separation device for a negative pressure multi-media filter tank, comprising: a filter tank body, wherein a connecting pipe is fixedly connected to the outer surface of the filter tank body, and further comprising: Two filter boxes are disposed on one side of the filter tank. One filter box is fixedly connected to an inlet pipe, and the other filter box is fixedly connected to an outlet pipe. The outlet pipe is fixedly connected to a connecting pipe. The other filter box is fixedly connected to an inlet pipe, which is fixedly connected to the inlet pipe. The other filter box is fixedly connected to an outlet pipe, which is fixedly connected to the outlet pipe. A sealing groove is formed on the outer surface of each filter box. A filter frame is slidably connected inside the sealing groove. A frame is slidably connected inside the filter frame. A filter screen is fixedly connected to the inner wall of the frame. Valves are provided on the outer surfaces of the outlet pipe, inlet pipe, outlet pipe, and inlet pipe.

[0007] Preferably, each of the filter frames is fixedly connected to a hanging ear on the opposite side away from the filter box, and a screw is movably connected to one side of each hanging ear. The filter box has multiple positioning grooves on one side, the hanging ear is slidably connected inside the positioning groove, and the screw is threadedly connected to the filter box.

[0008] Preferably, a fixing block is fixedly connected to each of the four corners of the inner wall of the filter frame, and a guide rod is fixedly connected to one side of each fixing block, with the guide rod slidably connected to the frame.

[0009] Preferably, the outer surface of the guide rod is provided with a spring, and the spring is fixedly connected to the fixing block and the frame respectively.

[0010] Preferably, a limit ring is fixedly connected to one end of the guide rod, and a pressure sensor is fixedly connected inside the filter frame.

[0011] Preferably, a handle is fixedly connected to one side of the filter frame, and a buzzer is fixedly connected to one side of the filter frame.

[0012] Preferably, a sealing gasket is slidably connected to the inner wall of the sealing groove, and the sealing gasket is fixedly connected to the filter frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 0. This utility model opens the valves of the second water outlet pipe and the second water inlet pipe, while closing the valves of the first water outlet pipe and the first water inlet pipe. Water flows sequentially through the first water inlet pipe into the second water inlet pipe, the filter box, the second water outlet pipe, and the first water outlet pipe. It is then transported to the filter tank via connecting pipes. By manually turning the screw, it is detached from the lower filter box. At this point, the lower filter frame can be pulled out of the lower filter box using a handle, and the filtered impurities can be cleaned. Conversely, the screw reattaches the filter frame, and with the help of a sealing gasket, a certain sealing effect is achieved. Thus, when the filter screen becomes clogged due to filtered impurities, the water flow path is changed, allowing the water to continuously flow into the filter tank through the connecting pipes without interruption, thereby ensuring the efficiency of the multi-media filter tank in filtering the water.

[0014] 1. This utility model uses a filter screen to filter impurities. As the amount of impurities filtered by the filter screen gradually increases, the resistance to the water increases, applying a force to the frame and the filter screen. This causes the frame to slide to one side along the outer surface of the guide rod, simultaneously compressing the spring. When the frame contacts the pressure sensor, the pressure sensor transmits a signal to the controller, which then controls the buzzer below to sound. This promptly notifies the staff that the filter screen has filtered a large amount of impurities and needs to be cleaned. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Examples, such as Figure 1-4 As shown, this utility model provides a separation device for a negative pressure multi-media filter tank, including: a filter tank body 1, with a connecting pipe 101 fixedly connected to the outer surface of the filter tank body 1; and two filter boxes 204 disposed on one side of the filter tank body 1. One filter box 204 has an inlet pipe 201 fixedly connected to one side, and an outlet pipe 204 fixedly connected to the other side of the other filter box 204. The outlet pipe 204 is fixedly connected to the connecting pipe 101. The other filter box 204 has an inlet pipe 203 fixedly connected to one side. Water pipe 203 is fixedly connected to water inlet pipe 201. Water outlet pipe 202 is fixedly connected to the other side of another filter box 204. Water outlet pipe 202 is fixedly connected to water outlet pipe 2. A sealing groove 210 is opened on the outer surface of the filter box 204. A filter frame 205 is slidably connected inside the sealing groove 210. A frame 3 is slidably connected inside the filter frame 205. A filter screen 301 is fixedly connected to the inner wall of the frame 3. Valves are provided on the outer surfaces of water outlet pipe 2, water inlet pipe 201, water outlet pipe 202 and water inlet pipe 203.

[0020] Furthermore, such as Figure 1-4As shown, each side of the filter frame 205 away from the filter box 204 is fixedly connected with a hanging ear 207, and each side of the hanging ear 207 is movably connected with a screw 208. The filter box 204 has multiple positioning grooves 211 on one side, and the hanging ear 207 is slidably connected inside the positioning groove 211. The screw 208 is threadedly connected to the filter box 204. With the above configuration, the filter frame 205 can be fixedly installed by rotating the screw 208 to connect it to the filter box 204.

[0021] Furthermore, such as Figure 1-4 As shown, a fixing block 304 is fixedly connected to each of the four corners of the inner wall of the filter frame 205. A guide rod 302 is fixedly connected to one side of the fixing block 304. The guide rod 302 is slidably connected to the frame 3. With the above settings, the frame 3 can slide along the outer surface of the guide rod 302.

[0022] Furthermore, such as Figure 1-4 As shown, a spring 305 is provided on the outer surface of the guide rod 302. The spring 305 is fixedly connected to the fixing block 304 and the frame 3 respectively. Under the reset force of the spring 305, the frame 3 and the filter screen 301 can be reset.

[0023] Furthermore, such as Figure 1-4 As shown, a limit ring 303 is fixedly connected to one end of the guide rod 302, and a pressure sensor 306 is fixedly connected inside the filter frame 205. The limit ring 303 plays a certain role in limiting the frame 3. When the frame 3 comes into contact with the pressure sensor 306, the signal can be transmitted to the controller.

[0024] Furthermore, such as Figure 1-4 As shown, a handle 206 is fixedly connected to one side of the filter frame 205, and a buzzer 209 is fixedly connected to one side of the filter frame 205. The handle 206 makes it easy to pull the filter frame 205 out of the filter box 204. The buzzer 209 makes it easy to remind the staff when it sounds.

[0025] Furthermore, such as Figure 1-4 As shown, a sealing gasket 212 is slidably connected to the inner wall of the sealing groove 210. The sealing gasket 212 is fixedly connected to the filter frame 205. The sealing gasket 212 achieves a certain sealing effect.

[0026] Working Principle: During use, the valves of outlet pipe 202 and inlet pipe 203 are closed, while the valves of outlet pipe 2 and inlet pipe 201 are open. When water enters the filter box 204 below through inlet pipe 201, impurities are filtered by filter screen 301. As the amount of impurities filtered by filter screen 301 increases, the resistance to the water increases, applying a force to frame 3 and filter screen 301. This causes frame 3 to slide to one side along the outer surface of guide rod 302, simultaneously compressing spring 305. When frame 3 contacts pressure sensor 306, pressure sensor 306 transmits a signal to controller, which then controls buzzer 209 below to sound. This promptly notifies staff that filter screen 301 has filtered a large amount of impurities and needs cleaning. At this time, staff can open the valves of outlet pipe 202 and inlet pipe 203, and open the valves of outlet pipe 202 and inlet pipe 201. When the valve of pipe 201 is closed, water flows through inlet pipe 201 into inlet pipe 203, filter box 204, outlet pipe 202, and outlet pipe 2, and is then transported to filter tank 1 through connecting pipe 101. The screw 208 is then manually turned to detach it from the lower filter box 204. At this point, the lower filter frame 205 can be pulled out of the lower filter box 204 using handle 206, and the impurities filtered by filter screen 301 can be cleaned. Conversely, the screw 208 is used to install the filter frame 205, which, with the cooperation of sealing gasket 212, achieves a certain sealing effect. Thus, when filter screen 301 becomes clogged due to filtered impurities, the water flow path is changed, allowing water to continuously flow into filter tank 1 through connecting pipe 101 without interruption, thereby ensuring the filtration efficiency of the multi-media filter tank 1. The frame 3 and filter screen 301 can be reset by the restoring force of spring 305.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
