Description

TECHNICAL FIELD

[0001] The utility model belongs to wastewater treatment equipment technical field, specifically, relate to the filter device for water circulation. BACKGROUND

[0002] The filter device for water circulation has various types and technologies, and their main purpose is to remove suspended solids, particulate matter, microorganisms and other impurities in water to purify water quality, reduce system fouling, algae, corrosion and other problems, and improve water reuse rate. For small area ponds, in order to remove the influence of fish excrement, food residue and other impurities on water quality, the water inside the pond is filtered in the concept of ecological environmental protection. In the process of filtering the water source, the top of the filter layer inside the filter device is often the area with the most impurities. In long-term use, the impurities in this area will gradually increase, and too many impurities can easily cause the filtration effect to decrease and the drainage efficiency to decrease. Sand filter layer is one of the filter layers, which is usually composed of different types and sizes of granular materials, such as quartz sand, quartz stone, activated carbon, etc. The size and shape of these filter materials are different, which is beneficial to increase the contact area of water and the filtration efficiency. Using high-pressure water to flush the surface of the sand filter layer can effectively stir the sand particles, making it easier for suspended solids to fall off. High-pressure water flushing may cause some physical wear and tear to the sand filter layer, but appropriate pressure and flushing time can reduce this risk.

[0003] The utility model discloses a filter tank with anti -blocking function for water treatment, and the utility model discloses a filter tank with anti -blocking function for water treatment, which comprises a tank body and a jet frame, the bottom of the tank body is fixed with a support, and the one side of the tank body is equipped with detection hole, the left side upper portion of the tank body is equipped with water inlet, and the bottom of the tank body is equipped with water outlet, and the bottom of the water outlet is connected with the sewage valve, the inside installation of the tank body has the fixed block, and the top of the fixed block is connected with the filter grid, the lower portion of the filter grid is provided with the filter chamber, and the inside of the filter chamber is filled with the filter material, and the bottom of the filter chamber is provided with the sedimentation chamber. The filter tank with anti -blocking function for water treatment through the mutual cooperation of the jet frame, the high -pressure nozzle and the pipe setting, when the inside of the tank body is blocked, the cleaning liquid is evenly distributed through the high -pressure nozzle on the surface of the jet frame, so that the harmful substances blocked on the surface of the filter grid can be dispersed. Although the scheme is not for cleaning the sand filter layer, the cleaning method can be used for reference, but if this cleaning method is used, the high -pressure water may not be evenly distributed, and the sand filter layer may be damaged while not being cleaned.

[0004] For example, the Chinese utility model patent authorization announcement No. CN215387854U, the application date is June 22, 2021, and the name is: a sewage treatment tank for sewage treatment equipment;The disclosed device includes a tank body, a tank cover is arranged at the top of the tank body, a motor is arranged at the top of the tank cover, a water inlet and a water pump are arranged on both sides of the motor, a rotating shaft is arranged at the bottom of the motor, a brush is arranged on the outer wall of the rotating shaft, a collecting groove is arranged on the outer wall of the tank body, and a first filter layer is arranged in the tank body. The scheme drives the brush to clean the first filter layer by the motor, prevents impurities from blocking the first filter layer. The cleaning method of the scheme, the brush directly contacts the filter layer for cleaning. Although this design has a larger cleaning area and no dead angle, the filter layer is more prone to wear due to physical friction, and other parts inside the device are not easy to disassemble and clean. SUMMARY

[0005] 1. Problem to be solved

[0006] In view of the technical problems of the existing filter device for water circulation, the filter layer is not cleaned, and is prone to wear during cleaning, the application provides a filter device for water circulation.

[0007] 2. Technical scheme

[0008] To solve the above problems, the technical scheme provided by the utility model is:

[0009] The filter device for water circulation comprises

[0010] A tank body is provided with a water inlet at the top, and a water outlet is communicated at the side of the bottom of the tank body;

[0011] A filter layer is installed in the interior of the tank body, and a space is left between the filter layer and the bottom end of the interior of the tank body;It also comprises a cleaning assembly;The cleaning assembly is composed of a flushing part and a blocking part, wherein

[0012] The flushing part is semi-surrounded on the outside of the tank body, one end of the flushing part is connected with the tank body, and the other end of the flushing part is connected with the outside high-pressure water pump.

[0013] The blocking part is symmetrically distributed with the center of the tank body around the flushing part, and is also arranged on the outside of the tank body.

[0014] Further, the tank body is provided with through holes at equal angles on the outside, the flushing part comprises a cleaning pipe penetrating the through holes, the cleaning pipe is at the top of the filter layer, and the two are in a state of adhesion, the other end of the cleaning pipe extends to the outside of the tank body, and the other end of the cleaning pipe is connected with a ring pipe, the top of the ring pipe is communicated with a water injection pipe, and the water injection pipe is connected with the outside high-pressure water pump.

[0015] By opening through holes at equal angles on the outside of the tank body and having the cleaning pipe pass through these through holes, the top of the filter layer can be directly flushed, which can more effectively remove impurities on the filter layer and improve cleaning efficiency and effect. Since the cleaning pipe is attached to the top of the filter layer instead of directly contacting the entire surface of the filter layer, this design can reduce wear and tear on the filter layer during cleaning and prolong the service life of the filter layer. The design of the cleaning pipe half-encircling the outside of the tank body helps to cover a wider area, reducing cleaning dead angles and ensuring comprehensive cleaning of the filter layer.

[0016] Further, the outside of the tank body is also provided with an arc groove, which is arranged symmetrically with the through hole along the center of the tank body, and the blocking piece includes an arc plate inserted into the arc groove, and the outer surface of the arc plate is fixed with an end plate.

[0017] The design of the arc plate and the end plate makes the blocking piece easily inserted and extracted from the arc groove, realizing quick blocking and opening of the through hole and facilitating cleaning operation when needed. Through the setting of the blocking piece, the through hole can be completely closed when not cleaning to prevent impurities from entering, and when cleaning is needed, the arc plate is extracted to realize cleaning of a specific area, improving the pertinence and efficiency of cleaning. The design of the blocking piece simplifies the operation process, and the operator only needs to extract the arc plate through the end plate to clean, without the need for complex operations or tools. The arc groove and the through hole are arranged symmetrically along the center of the tank body, enhancing the symmetry and stability of the structure and helping to improve the mechanical stability of the entire tank body.

[0018] Further, the outside of the tank body is also provided with at least two limiting plates, which are installed on the tank body by bolts, and the two limiting plates are respectively located at both ends of the arc plate.

[0019] The setting of the limiting plate provides fixation and support for the arc plate, enhancing the stability of the entire blocking piece structure and ensuring that the arc plate does not displace or fall off during operation. The limiting plate is located at both ends of the arc plate, which can accurately position the arc plate, ensuring that the arc plate is correctly inserted into the arc groove and improving the accuracy and reliability of blocking. The limiting plate installed by bolts is convenient for installation and maintenance, and can be quickly disassembled and reinstalled, facilitating regular inspection and maintenance work.

[0020] Further, the bottom of the opening of the arc groove is at the same level as the top surface of the filter layer.

[0021] The design of the same level makes the impurities directly slide or quickly flow out after being cleaned, improving the efficiency of impurity removal. Quickly removing impurities can reduce the residence time of impurities in the filter layer or the arc groove, reducing the risk of re-blocking. Since impurities can be quickly removed, the workload of manually cleaning the filter layer and the arc groove is reduced, making maintenance more convenient.

[0022] Further, the end of the water outlet is provided with a slot, and a filter plate is clamped in the slot, and the thickness of the filter plate is equal to the thickness of the slot.

[0023] The detachable design of the filter plate makes maintenance and replacement more convenient, and the filter plate can be quickly replaced as needed, reducing maintenance time. By observing the color change on the filter plate, it can be directly judged whether the filtered water quality meets the standard, providing a simple and effective water quality detection method.

[0024] Further, the inside of the tank body is also provided with a support plate, the filter layer is placed on the support plate, and a filter cap is also installed on the support plate.

[0025] The support plate provides stable support for the filter layer, ensuring that the filter layer will not displace or deform under water flow impact, enhancing the stability of the filter layer.

[0026] Further, the filter layer is a sand filter layer.

[0027] 3, beneficial effects

[0028] Compared with the prior art, the beneficial effects of the utility model are:

[0029] The filter device for water circulation of the utility model has the following advantages: (1) The design that the flushing part is attached to the top of the filter layer means that physical contact and friction are reduced during the cleaning process, thereby reducing the wear of the filter layer; at the same time, the flushing part is close to the top of the filter layer, and a cleaning water flow with a small pressure can achieve a relatively ideal cleaning effect, further prolonging the service life of the filter layer. (2) The flushing part is semi-surrounded outside the tank body, and such a design helps to cover a wider area, reduces cleaning dead angles, and ensures the overall cleaning of the filter layer. (3) A space is left between the filter layer and the bottom end of the inside of the tank body, which facilitates sampling. (4) Effective cleaning can prevent the filter layer from being blocked, keep the water flow unobstructed, and improve the efficiency of the water circulation system.

[0038] The utility model will be further described below in combination with specific embodiments.

[0039] The technical solutions in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0040] EMBODIMENT

[0041] The filter device for water circulation in the embodiment, as shown in the figure: Figures 1-4

[0042] includes tank body 100, the top of the tank body 100 is provided with water inlet 101, and the bottom side of the tank body 100 is communicated with water outlet 104. Filter layer 102 is installed in the inside of the tank body 100, and a spacing is left between the filter layer 102 and the bottom end of the inside of the tank body 100. Tank body 100 is the main component of the filter device, which is usually made of solid and durable materials to ensure water quality safety and equipment durability. Water inlet 101 is located at the top of tank body 100, which is beneficial to the natural descent of water flow and reduces the impact on filter layer 102. The design of the water inlet needs to ensure uniform distribution of water flow to improve filtration efficiency and reduce excessive wear in local areas. As a preferred, the design of the inside of the tank body 100 needs to consider water flow dynamics to ensure uniform distribution of water flow when entering filter layer 102, avoiding too fast or too slow water flow in local areas, which affects the filtration effect.

[0043] ​Also included is a cleaning assembly designed to periodically remove impurities and deposits accumulated on the filter layer 102, in order to maintain filtering efficiency and prolong the service life of the filter layer. This assembly is a key part of ensuring that water quality continues to meet standards. The cleaning assembly consists of a flushing element and a blocking element, where the flushing element is semi-enclosed on the outside of the tank 100, and one end of the flushing element is connected through the tank 100 and fits the top of the filter layer 102, while the other end of the flushing element is connected to an external high-pressure water pump. When the filter layer 102 needs to be cleaned, the high-pressure water pump sprays cleaning water through the cleaning pipe 205 to achieve cleaning of the filter layer 102. The high-pressure water pump is responsible for providing sufficient pressure to spray cleaning water through the cleaning pipe 205 to loosen and remove impurities on the filter layer 102.

[0044] In this embodiment, preferably, the tank 100 is externally equiangularly provided with a through hole, and the flushing element includes a cleaning pipe 205 that penetrates the through hole. The cleaning pipe 205 is at the top of the filter layer 102 and is in a fitted state, so that it can better remove impurities on the surface of the filter layer 102. It is worth noting here that the flushing element can remove a large amount of impurities on the filter layer 102, but not all of them. As long as the filtering effect of a large area is not affected, the filtering work can be ensured to proceed normally. The other end of the cleaning pipe 205 extends to the outside of the tank 100, and the other end of the cleaning pipe 205 is connected to a ring pipe 200. The top of the ring pipe 200 is connected to a water injection pipe 201, and the water injection pipe 201 is connected to an external high-pressure water pump. The high-pressure water is transmitted to the ring pipe 200 through the water injection pipe 201, and then distributed to each cleaning pipe 205 by the ring pipe 200. The ring pipe 200 and the water injection pipe 201 constitute a distribution system that evenly distributes the high-pressure water flow generated by the high-pressure water pump to each cleaning pipe 205. This distribution mechanism ensures that each cleaning area can obtain sufficient cleaning force. By controlling the pressure and flow of the high-pressure water pump, the operator can accurately control the cleaning process to adapt to different cleaning needs and conditions. This control capability helps to optimize the cleaning effect and reduce resource waste.

[0045] The blocking pieces are distributed in the center of the circle of the tank 100 and are also arranged on the outside of the tank 100. When cleaning is not needed, the drainage openings are blocked by the blocking pieces. When cleaning is needed, the blocking pieces are removed to achieve the purpose of discharging the impurities. The blocking pieces are arranged on the outside of the tank 100, so that the operator does not need to open the tank to perform the blocking or cleaning operation, which can reduce the operation complexity and improve the work efficiency. In the embodiment, preferably, an arc slot is also arranged on the outside of the tank 100, and the arc slot is arranged in the center of the circle of the tank 100 along with the through hole. The blocking piece includes an arc plate 202 clamped into the arc slot, and an end plate 203 is fixed to the outer surface of the arc plate 202. When cleaning is not needed, the arc plate 202 blocks the arc slot. When cleaning is needed, the arc plate 202 is pulled out of the arc slot through the end plate 203. The design that the arc plate 202 is clamped into the arc slot makes the blocking operation simple and fast. When cleaning is needed, the arc plate 202 can be easily pulled out of the arc slot through the end plate 203, achieving rapid release. The arc plate 202 needs to have good sealing performance when cooperating with the arc slot during blocking, so as to ensure that no water or impurities leak from the drainage opening when cleaning is not needed. The material selection of the arc plate 202 and the end plate 203 needs to consider water resistance, chemical corrosion resistance and wear resistance, so as to ensure the long-term use and reliability of the blocking piece.

[0046] In the embodiment, at least two limiting plates 204 are also arranged on the outside of the tank 100. The limiting plates 204 are installed on the tank 100 through bolts, and the two limiting plates 204 are respectively located at the two end positions of the arc plate 202, so as to achieve the installation of the arc plate 202. The two limiting plates 204 are respectively located at the two ends of the arc plate 202. This symmetrical layout helps to uniformly distribute the force received by the arc plate and reduce structural deformation or damage caused by uneven force. The design of the limiting plate 204 allows the arc plate 202 to be quickly installed and adjusted. This design simplifies the maintenance work, so that the operator can quickly replace or maintain the blocking piece. The bottom of the arc slot opening is at the same level as the top end surface of the filter layer 102, which facilitates the rapid discharge of the impurities after cleaning.

[0047] In the embodiment, the end of the water outlet 104 is provided with a slot 104a, and a filter plate 300 is clamped into the slot 104a. The thickness of the filter plate 300 is equal to the thickness of the slot 104a. The filtered water source is discharged through the filter plate 300. In the later stage, the filter plate 300 can be removed, and whether the filtered water source meets the standard can be determined by detecting whether the filter plate 300 presents yellow or brown color or other colors caused by unqualified water source. By observing the color change on the filter plate 300, the operator can intuitively evaluate the filtering effect. This visual detection method is simple and fast, and provides a low-cost solution for water quality monitoring. The easy-to-dismount design of the filter plate 300 allows the filter plate to be quickly replaced when it is detected that the water quality does not meet the standard, which reduces the downtime caused by water quality problems and improves the operation efficiency of the entire system.

[0048] In this embodiment, the inside of the tank body 100 is also provided with a support plate 103, and the filter layer 102 is placed on the support plate 103. The support plate 103 is also provided with a water filter cap, which is not shown in the figure. The water source filtered by the filter layer 102 can be discharged into the inside bottom end of the tank body 100 through the water filter cap, and finally discharged through the water outlet 104. The support plate 103 provides a stable support platform for the filter layer 102, ensuring that the filter layer will not collapse or deform under the impact of water flow, thereby maintaining the uniformity and filtering efficiency of the filter layer. The water filter cap is evenly installed on the support plate 103, which helps to evenly distribute the filtered water to the inside bottom end of the tank body 100, reducing the impact of uneven water force on the water outlet 104.
