Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, specifically an automatic filtration device for water quality testing. Background Technology

[0002] In today's society, water quality testing is of paramount importance for ensuring drinking water safety, maintaining ecological stability, and controlling quality in industrial production processes. Currently available water quality testing devices typically filter the water source before testing to remove impurities, suspended solids, and other interfering substances, aiming to obtain more accurate results. However, existing filtration devices have revealed significant shortcomings in practical use. Due to the diverse types and varying amounts of impurities in water sources, filtration devices are easily clogged after a period of use. Once clogged, water flow is impeded, affecting subsequent water quality testing.

[0003] To solve the problem of filter clogging, the common practice is to open the water quality testing device and clean and unclog the filter. However, this process is not only cumbersome and requires professional operators to spend a lot of time and effort, but opening the device may also introduce new impurities or contaminants, affecting the accuracy of the test results. In addition, frequently opening and closing the testing device will also cause some wear and tear on the device itself, shortening its service life.

[0004] Therefore, it is urgent to develop an automatic filtration device for water quality testing that can automatically remove impurities and avoid clogging. Utility Model Content

[0005] The purpose of this invention is to provide an automatic filtration device for water quality testing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic filtration device for water quality testing includes a base plate and a cylindrical outer shell fixedly mounted on the base plate. Hollow columns are symmetrically fixedly mounted on the top surface of the base plate and the inner wall of the cylindrical outer shell. A support plate is rotatably mounted between two hollow columns. The support plate is driven by a first motor installed inside one of the hollow columns. Multiple partitions are fixedly mounted on the side walls of both hollow columns. The cylindrical outer shell is configured with four chambers through the multiple partitions. Filter plates are installed on the support plate corresponding to the four chambers. An inlet pipe is also fixedly mounted on the top surface of the cylindrical outer shell. The inlet pipe is arched, and its two inlets are positioned corresponding to two chambers of the same diameter. An outlet is installed on the base plate corresponding to two inlet positions. A cleaning mechanism is installed in the other two chambers. The cleaning mechanism includes a cleaning roller rotatably mounted on the inner wall of the chamber. The cleaning roller is located above the support plate and is driven by a second motor installed inside the hollow column.

[0008] As a further embodiment of this utility model: a fixing pipe is fixedly installed in the chamber below the support plate, the fixing pipe is connected to the pump body installed in the hollow tube below, and multiple backwash nozzles are also arrayed on the fixing pipe.

[0009] As a further embodiment of this utility model: the cylindrical outer shell is also hinged to the side wall of the chamber where the cleaning mechanism is installed, and the inspection door is equipped with a handle.

[0010] As a further embodiment of this utility model, the filter plate is detachably mounted on the support plate by screws.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features four chambers, filter plates, and a cleaning mechanism. Only two of the four filter plates filter the water. After a period of filtration, the other two filter plates are rotated to the filtration position by controlling the first motor, enabling automatic replacement of the filter plates. During the replacement process, the replaced filter plates are cleaned, avoiding the tedious operation of frequently opening the device for cleaning due to filter plate blockage. This improves the efficiency of water quality testing and reduces wear and tear on the testing device.

[0013] The backwash nozzle of this invention can backwash the filter plate from bottom to top, further removing impurities from the filter plate pores, improving the cleaning effect, and ensuring the filtration performance of the filter plate. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments. Example

[0021] Please see Figure 1-5 An automatic filtration device for water quality testing includes a base plate 1 and a cylindrical outer shell 2 fixedly mounted on the base plate 1. Hollow columns 3 are symmetrically fixedly mounted on the top surface of the base plate 1 and the inner wall of the cylindrical outer shell 2. A support plate 4 is rotatably mounted between two hollow columns 3. The support plate 4 is driven by a first motor 5 installed inside one of the hollow columns 3. Multiple partitions 6 are fixedly installed on the side walls of both hollow columns 3. The cylindrical outer shell 2 is provided with four chambers 7 through the multiple partitions 6. Filter plates 8 are installed on the support plate 4 at the positions corresponding to the four chambers 7. A water inlet pipe 9 is also fixedly mounted on the top surface of the cylindrical outer shell 2. The water inlet pipe 9 is arched, and the two inlets of the water inlet pipe 9 are set at the two chambers 7 of the same diameter. An outlet is installed on the base plate 1 at the positions corresponding to the two water inlets. The water inlet 10 and the other two chambers 7 are equipped with cleaning mechanisms. The cleaning mechanisms include cleaning rollers 11 that are rotatably mounted on the inner wall of the chambers 7. The cleaning rollers 11 are located above the support plate 4 and are driven by a second motor installed in the hollow column 3. By setting up four chambers 7, filter plates 8 and cleaning mechanisms, only two of the four filter plates 8 filter the water. After filtering for a period of time, by controlling the first motor 5, the other two filter plates 8 can be rotated to the filtration position to realize the automatic replacement of the filter plates 8. During the replacement process, the replaced filter plates 8 are cleaned, avoiding the tedious operation of frequently opening the device for cleaning due to filter plate 8 blockage. This improves the efficiency of water quality detection and also reduces the wear and tear on the detection device. Example

[0022] Please see Figure 4A fixed pipe 12 is also fixedly installed in the chamber 7 below the support plate 4. The fixed pipe 12 is connected to the pump body installed in the hollow pipe below. Multiple backwash nozzles 13 are also arrayed on the fixed pipe 12. The backwash nozzles 13 can backwash the filter plate 8 from bottom to top, further removing impurities in the filter holes of the filter plate 8, improving the cleaning effect, and ensuring the filtration performance of the filter plate 8. Example

[0023] Please see Figure 1 The cylindrical outer shell 2 is also hinged to the side wall of the chamber 7 where the cleaning mechanism is installed. The inspection door 14 is equipped with a handle. The inspection door 14 facilitates the inspection and maintenance of the cleaning mechanism and the filter plate 8. When a malfunction occurs or more in-depth cleaning is required, the inspection door 14 can be opened in time for handling. Example

[0024] Please see Figure 5 The filter plate 8 is detachably mounted on the support plate 4 by screws 15. The filter plate 8 is detachable, which facilitates its replacement. When the filter plate 8 is damaged or reaches the end of its service life, it can be replaced easily and quickly to ensure the normal operation of the device.

[0025] Working principle:

[0026] During filtration, water enters two chambers 7 through the inlet pipe 9 and is filtered by the filter plates 8 within these chambers. The filtered water flows out from the outlet 10 on the bottom plate 1. After filtration for a period of time, the first motor 5 drives the support plate 4 to rotate 90°, rotating the other two unused filter plates 8 to the filtration position, thus automatically replacing the filter plates 8. During the rotation and replacement process, the cleaning roller 11 of the cleaning mechanism rotates under the drive of the second motor to clean the surface of the replaced filter plates 8. At the same time, the pump works, using the backwash nozzle 13 to backwash the filter plates 8, further removing impurities from the filter holes. If maintenance or repair of the cleaning mechanism or filter plates 8 is required, it can be operated by opening the maintenance door 14 through the handle. When a filter plate 8 is damaged, it can be replaced by removing the screws 15.

[0027] In summary, this automatic filtration device for water quality testing, through its reasonable structural design, achieves functions such as filtration, automatic plate replacement, cleaning, maintenance, and filter plate replacement, effectively solving the problems of easy clogging and cumbersome cleaning in existing filtration devices, and improving the efficiency of water quality testing and the service life of the device.
