Description

Technical Field

[0001] This utility model relates to the field of ecological environment monitoring technology, specifically a water sample filtration device. Background Technology

[0002] In the field of ecological and environmental monitoring technology, water sample analysis is the core link in assessing water quality and judging the degree of pollution. Water sample filtration, as a pretreatment step, directly affects the accuracy of subsequent test data. Only by removing impurities such as suspended solids and silt particles from the water sample can we avoid them interfering with the test results of water quality indicators. Therefore, water sample filtration devices are an indispensable piece of equipment in ecological and environmental monitoring work.

[0003] Currently, most devices on the market for filtering small batches of water samples use a cylinder and a filter plate as their core structure. After the water sample is injected into the cylinder, the filter plate traps impurities and purifies the water sample. However, in actual testing scenarios, when processing water samples containing a lot of suspended impurities, as the filtration process continues, the surface of the filter plate will continuously trap impurities, causing the filter holes to gradually become clogged, which in turn causes the water output speed to decrease significantly, or even the filtration to be interrupted.

[0004] The process requires operators to stop filtration, disassemble the device, and remove the filter plates for cleaning. This process not only interrupts the testing process and prolongs the pretreatment time, but also causes water sample contamination due to the disassembly operation, increasing the complexity of the operation. Therefore, there is an urgent need to develop a water sample filtration device to solve these practical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water sample filtration device that solves the technical problems of easy clogging of filter holes and cumbersome operation that leads to process interruption due to disassembly and cleaning in small-batch water sample filtration devices.

[0006] To achieve the above objectives, this utility model provides a water sample filtration device through the following technical solution: a cylinder for transferring water samples, a filter plate for filtering water samples is fixedly connected to the top of the cylinder, and an outlet pipe for discharging filtered water samples is fixedly connected to one side of the bottom of the cylinder.

[0007] It also includes a rotary anti-clogging mechanism for cleaning and preventing clogging of the filter plate. The rotary anti-clogging mechanism includes a hollow rotating shaft seat rotatably mounted on the top of the cylinder. A fixing frame is fixedly connected to the inner side of the hollow rotating shaft seat, and a shaft extending to the top of the inner side of the cylinder is fixedly connected to the bottom end of the fixing frame. A brush plate is fixedly connected to the bottom end of the shaft, and the bottom of the brush plate abuts against the outer surface of the top of the filter plate.

[0008] Preferably, a transfer collection hopper is also fixedly connected to the top of the hollow rotating shaft seat. The transfer collection hopper is funnel-shaped, and its bottom is connected to the top of the hollow rotating shaft seat to receive the filtered water sample and introduce it into the cylinder.

[0009] Preferably, a first anti-slip rubber sleeve is also fixed to the outer side of the hollow shaft seat by bonding, which is used to increase the friction between the operator's hand and the surface of the hollow shaft seat.

[0010] Preferably, it also includes a backwashing assembly, which includes a support rod for moving the piston head, a piston head that fits against the inner wall of the cylinder, and a push plate fixed to the bottom of the support rod for increasing the contact area with the operator's hand. The backwashing assembly is used to backwash the water sample in the cylinder by pushing the piston head to make the water sample flow backward through the filter plate.

[0011] Preferably, the support rod passes through the bottom end of the cylinder and is fixedly connected to the piston head. The outer diameter of the piston head is adapted to the inner diameter of the cylinder to achieve a sealing fit. The push plate is fixedly connected to the bottom end of the support rod, and the push plate is circular in shape.

[0012] Preferably, the front of the cylinder is provided with an installation groove, in which a PC water level plate for displaying the water level of the water sample inside the cylinder is embedded. A second anti-slip rubber sleeve is also fitted on the outside of the cylinder to increase the friction when the operator holds the cylinder.

[0013] This invention provides a water sample filtration device. Compared with the prior art, it has the following advantages.

[0014] 1. This utility model achieves real-time anti-clogging of the filter plate through a rotary anti-clogging mechanism. The operator holds the second anti-slip rubber sleeve on the outside of the cylinder to stabilize the device, and holds the first anti-slip rubber sleeve on the outside of the hollow rotating shaft seat with the other hand to rotate. The hollow rotating shaft seat drives the fixing frame and shaft to rotate, so that the brush plate slides along the surface of the filter plate to clean impurities. The filter holes can be restored to unobstructed without stopping the filtration process. This solves the cumbersome problem of frequent disassembly and cleaning of the filter plate required by traditional devices, avoids the decrease in filtration efficiency caused by filter hole blockage, and ensures continuous and stable water sample filtration.

[0015] 2. This utility model achieves deep cleaning of the filter plate through a backwashing component. After closing the outlet valve, clean water is injected. The operator pushes the push plate, which drives the support rod and piston head to move upward along the inner wall of the cylinder. The compressed clean water generates upward pressure, forcing the clean water to flow backward through the filter plate and flushing away small impurities inside the filter plate. After backwashing, the push plate is pulled back to its original position to discharge wastewater. This solves the problems of difficult disassembly and cleaning of filter plates and easy damage in traditional devices. It avoids the performance degradation of the filter plate caused by long-term adhesion of impurities, extends the service life of the filter plate, and ensures stable filtration effect of the device.

Detailed Implementation

[0022] 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.

[0023] refer to Figure 1-5 A water sample filtration device includes a cylinder 1 for transferring water samples, a filter plate 101 for filtering water samples is fixedly connected to the top inside the cylinder 1, and an outlet pipe 102 for discharging filtered water samples is fixedly connected to one side of the bottom of the cylinder 1.

[0024] It also includes a rotary anti-clogging mechanism 2 for cleaning and preventing clogging of the filter plate 101. The rotary anti-clogging mechanism 2 includes a hollow rotating shaft seat 201 rotatably mounted on the top of the cylinder 1. A fixing frame 202 is fixedly connected to the inner side of the hollow rotating shaft seat 201, and a shaft 203 extending to the top of the inner side of the cylinder 1 is fixedly connected to the bottom end of the fixing frame 202. A brush plate 204 is fixedly connected to the bottom end of the shaft 203, and the bottom of the brush plate 204 abuts against the top outer surface of the filter plate 101.

[0025] The top of the hollow rotating shaft seat 201 is also fixedly connected to a transfer collection hopper 205. The transfer collection hopper 205 is funnel-shaped, and its bottom is connected to the top of the hollow rotating shaft seat 201. It is used to receive the filtered water sample and introduce it into the cylinder 1.

[0026] The outer side of the hollow shaft seat 201 is also fixed with a first anti-slip rubber sleeve 206 by bonding, which is used to increase the friction between the operator's hand and the surface of the hollow shaft seat 201.

[0027] It also includes a backwashing assembly 3, which includes a support rod 301 for pushing the piston head 302 to move, a piston head 302 that is in contact with the inner wall of the cylinder 1, and a push plate 303 fixed to the bottom of the support rod 301 for increasing the contact area with the operator's hand. The backwashing assembly 3 is used to push the piston head 302 to make the water sample in the cylinder 1 flow backward through the filter plate 101 to achieve backwashing.

[0028] The support rod 301 passes through the bottom end of the cylinder 1 and is fixedly connected to the piston head 302. The outer diameter of the piston head 302 is matched with the inner diameter of the cylinder 1 to achieve a sealing fit. The push plate 303 is fixedly connected to the bottom end of the support rod 301, and the push plate 303 is circular in shape.

[0029] The cylinder 1 has an installation groove on the front, and a PC water level plate 4 for displaying the water level of the water sample inside the cylinder 1 is embedded in the installation groove. A second anti-slip rubber sleeve 5 is also fitted on the outside of the cylinder 1 to increase the friction when the operator holds the cylinder 1.

[0030] Working principle: First, open the valve on the outlet pipe 102 and pour the water sample to be filtered into the transfer collection hopper 205. After being guided by the transfer collection hopper 205, the water sample flows into the cylinder 1 through the inner hole of the hollow rotating shaft seat 201. Then, the water sample naturally seeps downwards and passes through the filter plate 101. Impurities in the water sample are intercepted by the filter plate 101. The filtered water sample falls into the bottom space of the cylinder 1 and is finally discharged to the external storage container through the outlet pipe 102, thus completing the filtration.

[0031] During this process, the operator can observe the remaining amount of water sample in the cylinder through the PC water level plate 4 and replenish the water sample to be filtered in time. After the filtration has been carried out for a period of time, if the water flow rate of the outlet pipe 102 is significantly slower, it indicates that the impurities trapped on the surface of the filter plate 101 have increased and the filter holes have begun to be blocked. The operator holds the second anti-slip rubber sleeve 5 on the outside of the cylinder 1 with one hand to stabilize the device, and holds the first anti-slip rubber sleeve 206 on the outside of the hollow rotating shaft seat 201 with the other hand, and rotates the hollow rotating shaft seat 201 clockwise or counterclockwise.

[0032] When the hollow rotating shaft seat 201 rotates, it drives the inner fixed frame 202 and shaft 203 to rotate synchronously, which in turn drives the brush plate 204 at the bottom of the shaft 203 to slide along the top surface of the filter plate 101. The bristles at the bottom of the brush plate 204 sweep away the impurities trapped in the filter plate 101, realizing real-time cleaning of the filter plate 101. This operation can restore the pores of the filter plate 101 without stopping the filtration, avoiding the problem of decreased filtration efficiency caused by pore blockage, and solving the cumbersome operation problem of traditional filtration devices that require frequent disassembly and cleaning of the filter plate.

[0033] After filtration is completed, close the valve on the outlet pipe 102 and inject an appropriate amount of clean water into the cylinder 1. The water level can be observed through the PC water level plate 4. Then, the operator holds the second anti-slip rubber sleeve 5 with one hand to stabilize the cylinder 1 and pushes the push plate 303 upward with the other hand. The push plate 303 drives the support rod 301 to move upward, which in turn pushes the piston head 302 to slide upward along the inner wall of the cylinder 1.

[0034] When the piston head 302 moves upward, it compresses the clean water space at the bottom of the cylinder 1, causing the clean water inside the cylinder to generate upward pressure. The pressure forces the clean water to flow backward through the filter plate 101, washing away the fine impurities attached to the inside of the filter plate 101. After the backwashing is completed, the valve of the outlet pipe 102 is opened, and the push plate 303 is pulled down to drive the piston head 302 to reset. The flushing wastewater inside the cylinder can be discharged through the outlet pipe 102. This operation achieves deep cleaning of the filter plate 101, avoids the long-term adhesion of impurities leading to the performance degradation of the filter plate 101, and solves the technical problems of difficult disassembly and cleaning of filter plates and easy damage in traditional filtration devices.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
