Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, and in particular to a chemical dosing and unblocking device for water purification stations. Background Technology

[0002] When purifying chemical pollutants in water at a water purification station, chemicals are needed for neutralization and filtration. However, large-scale water purification stations often require the addition of large quantities of chemicals at once, especially solid chemicals. Without proper stirring, these chemicals can clump and settle upon entering the water tank, affecting the purification effect. Patent CN202322400855.0 discloses a chemical dosing device for water purification stations, including a water tank with inlet and outlet pipes horizontally connected to both sides. A support beam is horizontally suspended above the tank, and a strainer is fixedly connected to the center of the bottom surface of the support beam. A stirring mechanism is rotatably connected inside the strainer. A storage tank connected to the strainer is located on the top surface of the support beam, and a feeding pipe is vertically connected to the top surface of the storage tank. This device aims to solve the aforementioned problems.

[0003] However, the above-mentioned patent has the following problems in use: In order to solve the problem of the agent clogging the feed inlet, an air pump is fixed horizontally on one side of the support beam. The output end of the air pump is connected to the elbow air pipe. The elbow air pipe passes through the support beam and extends into the feed inlet. The air pump sprays gas into the feed inlet to break up the clumps of the agent. Due to the presence of the elbow air pipe, the feed inlet cannot be closed, and the storage tank cannot store excess agent. Utility Model Content

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A chemical dosing and unblocking device for a water purification station includes a support beam, a storage tank, a strainer, and a drive motor. The storage tank and the drive motor are both fixedly installed on the upper end face of the support beam, and the strainer is fixedly installed on the lower end face of the support beam. The output shaft of the drive motor is connected to a rotating shaft, which passes through the support beam and the strainer in sequence. The rotating shaft is equipped with several stirring rods. The support beam has a feeding channel inside, one end of which is connected to the bottom surface of the storage tank, and the other end of which is connected to the upper end face of the strainer. An electric valve for controlling the opening and closing of the feeding channel is provided at the connection between the bottom surface of the storage tank and the feeding channel. An unblocking component is hinged in the feeding channel and is located below the electric valve.

[0006] Furthermore, the unblocking assembly includes a first hinge rod, a second hinge rod, and a third hinge rod. One end of the first hinge rod is hinged to the inner wall of the feed channel, and the other end is hinged to one end of the second hinge rod. The other end of the second hinge rod is hinged to one end of the third hinge rod. The other end of the third hinge rod passes through the support beam and extends to the outside of the support beam, and is slidably adapted to the support beam. The end of the first hinge rod that is hinged to the second hinge rod is also provided with an unblocking rod, which faces the electric valve. The first hinge rod, the second hinge rod, and the unblocking rod are all located in the feed channel.

[0007] Furthermore, the unblocking rod has inclined hooks evenly distributed on both sides, one end of which is fixedly connected to the unblocking rod, and the hooks are inclined downwards from that end.

[0008] Furthermore, the inclination angle A between the hook rod and the unblocking rod is 15°-30°.

[0009] Furthermore, the third hinge rod is inclined downwards.

[0010] Furthermore, the storage tank is provided with an observation window, and the observation window is provided with a scale.

[0011] The beneficial effects of this utility model are:

[0012] 1. When not in use, closing the electric valve allows excess chemicals to be stored in the storage tank, and the unclogging component effectively disperses any clumps of chemicals, preventing blockages.

[0013] 2. The cross-sectional shape of the feeding channel is trumpet-shaped, with a structure that is smaller at the top and larger at the bottom. When the agent enters the feeding channel from the small opening, it can effectively reduce the probability of the agent getting stuck in the feeding channel and improve the agent drop efficiency.

[0014] 3. The upward movement of the unblocking rod breaks up the clumped medicine, and as the unblocking rod moves downward, it also pulls the medicine downward, further improving the efficiency of the medicine falling. Attached Figure Description

[0026] refer to Figures 1-5 As shown, one embodiment of this utility model is as follows:

[0027] A chemical dosing and unblocking device for a water purification station includes a support beam 1, a storage tank 2, a strainer 3, and a drive motor 11. The storage tank 2 and the drive motor 11 are both fixedly installed on the upper end face of the support beam 1, and the strainer 3 is fixedly installed on the lower end face of the support beam 1. The output shaft of the drive motor 11 is connected to a rotating shaft 12, which passes through the support beam 1 and the strainer 3 in sequence. Several stirring rods 13 are provided on the rotating shaft 12. The support beam 1 has a feeding channel 4 inside. One end of the feeding channel 4 is connected to the bottom surface of the storage tank 2, and the other end of the feeding channel 4 is connected to the upper end face of the strainer 3. An electric valve 5 for controlling the opening and closing of the feeding channel 4 is provided at the connection between the bottom surface of the storage tank 2 and the feeding channel 4. An unblocking component is hinged in the feeding channel 4 and is located below the electric valve 5.

[0028] The working process of this utility model is as follows: In this utility model, the support beam 1 is fixedly installed on the existing water tank. The installation method and the structure of the water tank are existing technologies and will not be described in detail here. First, the required chemicals for the water purification station are added to the storage tank 2. Then, the electric valve 5 is opened, allowing the chemicals in the storage tank 2 to fall into the filter bucket 3 under gravity through the feed channel 4. At this time, the drive motor 11 is running, driving the rotating shaft 12 and the stirring rod 13 to rotate. When the chemicals fall into the filter bucket 3, they are broken up by the stirring rod 13 and rubbed against the side wall of the filter bucket 3 into smaller particles, allowing the chemicals to completely dissolve in the water. Furthermore, if clumps of chemicals clog the electric valve 5 after it is opened, the unblocking component can be used to push the chemicals from the storage tank 2 into the filter bucket 3. When not in use, closing the electric valve 5 allows excess chemicals to be stored in the storage tank 2.

[0029] Storage tank 2 is used to store the chemicals required by the water purification station, such as... Figure 1 and Figure 4 As shown, the upper end of the storage tank 2 is provided with a feeding port. Chemical agents required for the water purification station can be added to the storage tank 2 through this feeding port. In daily storage, in order to avoid the agents being affected by the external environment, they usually need to be stored in a sealed manner. Therefore, a sealing cap can be threaded onto the feeding port. That is, the feeding port is provided with an external thread, and the sealing cap is provided with a matching internal thread. When it is necessary to add agents to the storage tank 2, the sealing cap can be rotated off. After adding, the sealing cap can be rotated and tightened. The operation is simple, convenient and quick while ensuring airtightness. It should be noted that when not adding agents, the electric valve 5 is always in the closed state to ensure that the storage tank 2 is in a sealed state.

[0030] In this invention, the cross-sectional shape of the feeding channel 4 is trumpet-shaped, wherein the small opening of the trumpet shape is connected to the bottom surface of the storage tank 2, and the electric valve 5 is also located at the small opening of the trumpet shape; the large opening of the trumpet shape is connected to the upper end of the leaking bucket 3; since the feeding channel 4 has a structure that is smaller at the top and larger at the bottom, when the medicine enters the feeding channel 4 from the small opening of the feeding channel 4, the probability of the medicine getting stuck in the feeding channel 4 can be effectively reduced, and the falling efficiency of the medicine can be improved.

[0031] When clumped medicine blocks the electric valve 5, the unblocking component can push the medicine down from the storage tank 2 into the feed channel 4; specifically, as shown... Figure 2 and Figure 3 As shown, the unblocking assembly includes a first hinge rod 6, a second hinge rod 7, and a third hinge rod 8. One end of the first hinge rod 6 is hinged to the inner wall of the feed channel 4, and the other end is hinged to one end of the second hinge rod 7. The middle part of the second hinge rod 7 is hinged to one end of the third hinge rod 8. The other end of the third hinge rod 8 passes through the support beam 1 and extends to the outside of the support beam 1, and is slidably adapted to the support beam 1. The end of the first hinge rod 6 that is hinged to the second hinge rod is also provided with an unblocking rod 9, which is directly opposite the electric valve 5. The first hinge rod 6, the second hinge rod 7, and the unblocking rod 9 are all located in the feed channel 4.

[0032] like Figure 3 As shown, when the unblocking component is not needed to clear the blockage, the first hinge rod 6, the second hinge rod 7, and the third hinge rod 8 remain relatively stable. One end of the second hinge rod 7 abuts against the side wall of the feed channel 4 to maintain the overall stability of the first hinge rod 6, the second hinge rod 7, and the third hinge rod 8. At this time, the unblocking rod 9 is located in the feed channel 4, and the other end of the third hinge rod 8 passes through the support beam 1 and extends to the outside of the support beam 1 and the water tank. Figure 2 As shown, when it is necessary to clear the blockage of the agent, the electric valve 5 opens and the agent falls. If the agent is blocked at the electric valve 5, the operator can manually push the third hinge rod 3 forward to one end extending outside the water tank, causing the third hinge rod 8 to move. The movement of the third hinge rod 8 drives the second hinge rod 7 and the first hinge rod 6 to rotate. The first hinge rod 6 rotates upward at its hinge point with the feed channel 4. During the upward rotation of the first hinge rod 6, the clearing rod 9 moves upward and passes through the electric valve 5 to the storage tank 2, pushing the agent and breaking up the clumps of agent. Some of the broken agent falls into the feed channel 4. Then, the third hinge rod 8 is pulled back, and the clearing rod 9 moves downward. During the downward movement of the clearing rod 9, the agent also moves downward, further improving the efficiency of the agent falling. Of course, in actual operation, the third hinge rod 8 can be pulled back and forth repeatedly, causing the clearing rod 9 to move up and down to speed up the falling of the agent.

[0033] To prevent the unblocking rod 9 from rotating excessively and colliding with the electric valve 5, the third hinge rod 8 is also provided with a locking block at one end extending out of the water tank. When the locking block abuts against the side of the water tank, the unblocking rod 9 rotates to a vertical state.

[0034] In this invention, since the path of the unblocking rod 9 moving up and down is arc-shaped, in order to avoid the electric valve 5 affecting the unblocking rod 9 when it is closed or opened, the electric valve 5 preferably uses an existing powder spherical valve. The opening method of this powder spherical valve is to rotate the valve to be close to the side of the valve port. Therefore, by using this existing powder spherical valve and ensuring that when it is open, the valve is close to the side of the valve port away from the rotation direction of the unblocking rod 9, it is possible to ensure that the normal opening and closing of the electric valve 5 will not affect the normal rotation of the unblocking rod 9.

[0035] Specifically, the unblocking rod 9 has inclined hook rods 10 evenly distributed on both sides. One end of the hook rod 10 is fixedly connected to the unblocking rod 9, and the hook rod 10 is inclined downwards from that end. Figure 5 As shown, a conical structure is formed between the top of the unblocking rod 9 and the hook rods 10 on both sides. During the upward movement of the unblocking rod 9, the conical structure reduces the area of ​​the force-bearing point, increasing pressure and allowing the unblocking rod 9 to more quickly break up clumps of medicine, improving the dispersing efficiency. Furthermore, the downwardly inclined hook rods 10 also act as a diverter, facilitating the free fall of the medicine while also allowing the unblocking rod 9 to move upward quickly. A conical space is also left between the downwardly inclined hook rods 10 and the unblocking rod 9. When the unblocking rod 9 is inserted into the storage tank 2, some of the medicine falls into this conical space. When the unblocking rod 9 moves downward, it quickly carries the medicine in the conical space into the feeding channel 4, further accelerating the efficiency of the medicine falling into the feeding channel 4.

[0036] Specifically, the inclination angle A between the hook rod 10 and the unblocking rod 9 is 15°-30°. The 15°-30° inclination angle utilizes the component of gravity to promote the directional flow of the agent, and this angle range can effectively decompose the load and reduce the impact of the lateral force of the agent on the hook rod 10.

[0037] Specifically, the third hinge rod 8 is inclined downwards. In this utility model, as... Figure 2 and Figure 3As shown, the third hinge rod 8 is slidably adapted to the support beam 1, that is, a through hole is provided on the support beam 1, and the third hinge rod 8 is slidably located in the through hole. In actual use, in order to avoid the agent accumulating in the through hole of the support beam 1 and affecting the normal use of the third hinge rod 8, the third hinge rod 8 is tilted downward, and the tilt angle is preferably 3°-5°, that is, the through hole is also tilted downward. Since the through hole is tilted downward, the agent is not easy to fall into the through hole at the opening of the through hole. On the other hand, under the action of the component of gravity and the pushing action of the third hinge rod 8, the agent can also be quickly pushed out of the through hole, and the agent is not easy to accumulate, thus ensuring the normal use of the third hinge rod 8.

[0038] Specifically, to facilitate observation of the amount of medicine added, the storage tank 2 is equipped with an observation window with graduations. The observation window is made of transparent glass and is a vertical strip installed on the storage tank 2. The graduations allow for observation of the storage status of the medicine in the storage tank 2 at any time. Of course, for some medicines that need to be stored in the dark, existing peelable adhesive can be used to attach sunshade material to the observation window during storage. When adding the medicine, the sunshade material can be removed, and it can be reattached when storing.
