[0002] In the wastewater treatment process, disinfectant powder is a key disinfectant ingredient, and its effective addition is crucial to killing harmful microorganisms in the water and ensuring that the effluent quality meets the standards.

[0003] However, in actual operation, an often overlooked problem is the storage environment of disinfectant powder. In order to facilitate workers to use it, disinfectant powder is often stored near the wastewater treatment area, where the humidity is usually high. Disinfectant powder is very likely to clump in a high humidity environment for a long time, and the clumped disinfectant powder will clog the filter screen, thereby affecting the efficiency of disinfectant powder addition. In addition, due to the clogging of the filter screen, the disinfectant powder may also be unevenly added, thereby affecting the disinfection effect of wastewater treatment. Summary of the invention

The spaced side is in the same direction as the compression direction of the adjacent telescopic member.

[0017] As a preferred embodiment of the disinfectant powder dosing device for wastewater treatment according to the present invention, the following is provided: Each of the pair of telescopic members includes a fixed rod fixedly connected to the moving block and a fixed plate fixedly connected to the outer wall of the crushing and filtering frame. The side of the fixed rod away from the moving block movably passes through the crushing and filtering frame and is fixedly connected to a second arc-shaped convex block. The orientations of the pair of second arc-shaped convex blocks are opposite. The fixed plate is arranged on the side of the fixed rod away from the second arc-shaped convex block. A plurality of T-shaped sliding rods are fixedly connected to the side of the fixed rod away from the second arc-shaped convex block. The side of the T-shaped sliding rod away from the fixed rod slidably penetrates through the fixed plate. A plurality of return springs are fixedly connected between the fixed rod and the fixed plate. The plurality of return springs are respectively movably sleeved outside the T-shaped sliding rods. The first arc-shaped convex block is in movable contact with the side of the adjacent second arc-shaped convex block facing the crushing and filtering frame.

[0018] As a preferred embodiment of the disinfectant powder dosing device for wastewater treatment according to the present invention, the following is provided: The synchronization component includes a U-shaped rod movably sleeved on one side of the crushing and filtering frame.

A third arc-shaped convex block is fixedly connected to the side of the second extrusion rod facing the fixed rod. The third arc-shaped convex block is in movable contact with the side of the adjacent second arc-shaped convex block away from the crushing and filtering frame.

[0019] As a preferred embodiment of the disinfectant powder dosing device for wastewater treatment according to the present invention, the following is provided: Stabilizing rods are slidably penetrated through both sides of the crushing and filtering frame on the U-shaped rod. One end of the stabilizing rod is fixedly connected to the crushing and filtering frame.

[0020] The dosing method using the above-mentioned disinfectant powder dosing device for wastewater treatment includes the following steps:

[0021] Step 1: First, add an appropriate amount of disinfection powder between a pair of moving blocks of each crushing and filtering frame through the material storage unit;

[0022] Step 2: Then, start the driving motor. The output end of the driving motor drives the turntable to rotate clockwise. The turntable drives the arc-shaped moving groove to rotate accordingly. During the clockwise rotation of the arc-shaped moving groove, the inner wall of the arc-shaped moving groove can apply a pulling force to the convex post. Thus, the push rod can be pulled to move along the inside of the guiding sliding sleeve through the convex post. The push rod pulls the first extrusion rod and the C-shaped rod to move. Among them, the first extrusion rod pulls the first arc-shaped convex block to move away from the moving crushing and filtering frame. The second arc-shaped convex block drives the fixed rod to squeeze the return spring under the extrusion of the first arc-shaped convex block, and the return spring is compressed. During the process of the return spring being compressed, the fixed rod drives the moving block fixedly connected to it to move; when the C-shaped rod moves, it drives the third arc-shaped convex block to move towards the crushing and filtering frame through the second extrusion rod. The second arc-shaped convex block in contact with it drives the fixed rod to squeeze the return spring under the extrusion of the third arc-shaped convex block, and the return spring is compressed. During the process of the return spring being compressed, the fixed rod drives the moving block fixedly connected to it to move. The moving directions of the two moving blocks are opposite. Therefore, under mutual friction, the agglomerated disinfection powder can be preliminarily crushed. After the crushed disinfection powder and the unagglomerated disinfection powder are filtered through the filter mesh plate, they are added to the wastewater tank through the second material leakage port and the first material leakage port;

[0023] Step 3: After that, when the first arc-shaped convex block and the third arc-shaped convex block pass through the second arc-shaped convex block, the second arc-shaped convex block, the fixed rod and a pair of moving blocks move and reset under the restoring force of the return spring. And during the reset process, the agglomerated disinfection powder can also be further crushed between the pair of moving blocks;

[0024] Step 4: After that, after the moving block is reset, the driving motor drives the turntable to rotate counterclockwise. The turntable drives the arc-shaped moving groove to rotate accordingly. During the counterclockwise rotation of the arc-shaped moving groove, the inner wall of the arc-shaped moving groove can exert a driving force on the convex post. Thus, the push rod can be pushed by the convex post to move along the inside of the guiding sliding sleeve. The push rod pushes the first extrusion rod and the U-shaped rod to move. Among them, the first extrusion rod pushes the first arc-shaped convex block to move towards the pulverizing and filtering frame. The second arc-shaped convex block drives the fixed rod to squeeze the reset spring again under the extrusion of the first arc-shaped convex block, and the reset spring is compressed. During the process of the reset spring being compressed, the fixed rod drives the moving block fixedly connected thereto to move again. When the U-shaped rod moves, it drives the third arc-shaped convex block to move away from the pulverizing and filtering frame through the second extrusion rod. The second arc-shaped convex block in contact with it drives the fixed rod to squeeze the reset spring again under the extrusion of the third arc-shaped convex block, and the reset spring is compressed. During the process of the reset spring being compressed, the fixed rod drives the moving block fixedly connected thereto to move again. The moving directions of the two moving blocks are also opposite. Therefore, under mutual friction, the caked disinfectant powder can be pulverized again. By repeating this cycle and continuously rubbing the disinfectant powder back and forth between a pair of moving blocks, the purpose of thoroughly pulverizing the caked disinfectant powder can be achieved, and the filtering efficiency can be improved.

[0025] Advantages of the present invention:

[0026] 1. In the present invention, the filtering and dosing unit adopts a circular uniform distribution design, which can improve the dosing uniformity of the disinfectant powder, and further improve the sewage treatment effect.

[0027] 2. In the present invention, the disinfectant powder is added between a pair of moving blocks in the pulverizing and filtering frame through the storage unit, and then a pair of moving blocks are driven to move back and forth by the driving mechanism. On the one hand, it can accelerate the efficiency of the disinfectant powder passing through the filter mesh plate, thereby improving the dosing efficiency of the disinfectant powder. On the other hand, it can rub the caked disinfectant powder back and forth, so as to achieve the purpose of thoroughly pulverizing the caked disinfectant powder, and further improve the filtering efficiency, thereby improving the dosing efficiency of the disinfectant powder.

[0028] 3. In the present invention, the filter mesh plates with a staircase structure are assembled on the opposite sides of a pair of moving blocks. Such a design ensures that even when the amount of disinfectant powder is small, the filter mesh plate can still effectively pulverize the disinfectant powder. In addition, the tread surface of the staircase structure is designed as an inclined surface. Such a design enables the incompletely pulverized disinfectant powder to smoothly slide down along the inclined surface and continue to be pulverized by the friction of a pair of moving blocks. The pulverizing effect is good, and it is not easy to cause blockage of the filter mesh plate, and thus it is not easy to affect the dosing efficiency of the disinfectant powder.

In addition, a control valve is installed on each shunt feeding pipe 203 for controlling the opening and closing of the shunt feeding pipe 203. The number of the shunt feeding pipes 203 is consistent with that of the crushing and filtering mechanism 302, and they correspond one to one.

[0052] Specifically, Figure 5-6The driving mechanism 301 includes a chassis 301-1 located at the center of the discharge box 100, a plurality of connecting rods 301-2 evenly fixed to the periphery of the chassis 301-1, a fixed plate 301-3 fixedly connected to the top center of the chassis 301-1, a guide sleeve 301-4 fixedly connected to the periphery of the fixed plate 301-3 in a circular array, a turntable 301-5 movably connected to the top center of the fixed plate 301-3, and a driving motor 301-6 fixedly connected to the bottom of the chassis 301-1 by bolts. The top output end of the driving motor 301-6 movably passes through the chassis 301-1 and the fixed plate 301-3 and is fixedly connected to the center of the turntable 301-5. The purpose of this arrangement is that when the driving motor 301-6 is started, the turntable 301-5 can be driven to rotate by the driving motor 301-6.

In addition, the inner walls of both ends of the arc-shaped movable groove 301-9 are semicircular. In the initial state, the boss 301-8 is adapted to be plugged into the semicircular adapter away from the center of the turntable 301-5. In addition, the distance between the center of one semicircular arc and the center of the turntable 301-5 is greater than the distance between the center of the other semicircular arc and the center of the turntable 301-5.

A second leakage opening 302-23 is provided at the bottom of the pair of movable blocks 302-21, and the second leakage opening 302-23 is connected to the first leakage opening 302-3. With this arrangement, after the disinfectant powder is filtered through the filter screen plate 302-22, it can fall to the first leakage opening 302-3 through the second leakage opening 302-23, and then be added to the wastewater pool through the first leakage opening 302-3.

[0059] A pair of moving blocks 302-21 are both laterally sealed and slidably connected to both sides of the crushing filter frame 302-1, and the sides of the moving blocks 302-21 that are away from each other are fixedly connected to a pair of telescopic parts 302-4 respectively.

The T-shaped slide bars 302-44 slide through the fixed plate 302-42 away from the side of the fixed rod 302-41, and a plurality of return springs 302-45 are fixedly connected between the fixed rod 302-41 and the fixed plate 302-42. The plurality of return springs 302-45 are respectively movably sleeved on the outside of the T-shaped slide bars 302-44, and the first arc-shaped protrusion 301-11 is movably contacted with the adjacent second arc-shaped protrusion 302-43 toward one side of the crushing filter frame 302-1.

[0061] Specifically, as Fig.12 , the synchronization component 302-5 includes a U-shaped rod 302-51 movably sleeved on one side of the crushing and filtering frame 302-1. One end of the U-shaped rod 302-51 is fixedly connected to the first extrusion rod 301-10, and the other end is fixedly connected to a second extrusion rod 302-52. On the side of the second extrusion rod 302-52 facing the fixed rod 302-41, a third arc-shaped convex block 302-53 is fixedly connected. The third arc-shaped convex block 302-53 is in movable contact with the side of the adjacent second arc-shaped convex block 302-43 away from the crushing and filtering frame 302-1. When the third arc-shaped convex block 302-53 exerts a driving force on the second arc-shaped convex block 302-43, the second arc-shaped convex block 302-43 will be squeezed to retreat, thereby promoting the movement of the moving block 302-21.

[0062] Furthermore, stabilizing rods 302-54 are slidably penetrated through both sides of the crushing and filtering frame 302-1 on the U-shaped rod 302-51. One end of the stabilizing rod 302-54 is fixedly connected to the crushing and filtering frame 302-1. By setting the stabilizing rods 302-54, the stability of the U-shaped rod 302-51 is improved, enabling it to move smoothly.

[0063] The dosing method of using the above-mentioned dosing device for disinfectant powder for wastewater treatment is as follows:

[0064] First, an appropriate amount of disinfectant powder is added between a pair of moving blocks 302-21 of each crushing and filtering frame 302-1 through the storage unit 200.

[0065] Then, start the driving motor 301. The output end of the driving motor 301 drives the turntable 301-5 to rotate clockwise. The turntable 301-5 drives the arc-shaped moving groove 301-9 to rotate accordingly. During the clockwise rotation of the arc-shaped moving groove 301-9, the inner wall of the arc-shaped moving groove 301-9 can apply a pulling force to the convex post 301-8. Thus, through the convex post 301-8, the push rod 301-7 can be pulled to move along the inside of the guiding sliding sleeve 301-4. The push rod 301-7 pulls the first extrusion rod 301-10 and the U-shaped rod 302-51 to move. Among them, the first extrusion rod 301-10 pulls the first arc-shaped convex block 301-11 to move away from the moving crushing and filtering frame 302-1. The second arc-shaped convex block 302-43 drives the fixed rod 302-41 to extrude the reset spring 302-45 under the extrusion of the first arc-shaped convex block 301-11, and the reset spring 302-45 is compressed. During the process of the reset spring 302-45 being compressed, the fixed rod 302-41 drives the moving block 302-21 fixedly connected thereto to move. When the U-shaped rod 302-51 moves, it drives the third arc-shaped convex block 302-53 to move towards the crushing and filtering frame 302-1 through the second extrusion rod 302-52. The second arc-shaped convex block 302-43 in contact with it drives the fixed rod 302-41 to extrude the reset spring 302-45 under the extrusion of the third arc-shaped convex block 302-53, and the reset spring 302-45 is compressed. During the process of the reset spring 302-45 being compressed, the fixed rod 302-41 drives the moving block 302-21 fixedly connected thereto to move. The moving directions of the two moving blocks 302-21 are opposite. Therefore, under mutual friction, the agglomerated disinfection powder can be preliminarily crushed. After the crushed disinfection powder and the non-agglomerated disinfection powder are filtered by the filter mesh plate 302-22, they are added to the waste water tank through the second material leakage port 302-23 and the first material leakage port 302-3.

[0066] After that, when the first arc-shaped convex block 301-11 and the third arc-shaped convex block 302-53 pass through the second arc-shaped convex block 302-43, the second arc-shaped convex block 302-43, the fixed rod 302-41 and the pair of moving blocks 302-21 move and reset under the resilience of the reset spring 302-45. And during the reset process, the pair of moving blocks 302-21 can also further crush the agglomerated disinfection powder.

[0067] After the moving block 302-21 is reset, the turntable 301-5 is driven by the driving motor 301 to rotate counterclockwise. The turntable 301-5 drives the arc-shaped moving groove 301-9 to rotate accordingly. During the counterclockwise rotation of the arc-shaped moving groove 301-9, the inner wall of the arc-shaped moving groove 301-9 can exert a driving force on the convex post 301-8. Thus, the push rod 301-7 can be pushed by the convex post 301-8 to move along the inside of the guiding sliding sleeve 301-4. The push rod 301-7 pushes the first extrusion rod 301-10 and the U-shaped rod 302-51 to move. Among them, the first extrusion rod 301-10 pushes the first arc-shaped convex block 301-11 to move towards the pulverizing and filtering frame 302-1. The second arc-shaped convex block 302-43 drives the fixed rod 302-41 to squeeze the return spring 302-45 again under the extrusion of the first arc-shaped convex block 301-11, and the return spring 302-45 is compressed. During the process of the return spring 302-45 being compressed, the fixed rod 302-41 drives the moving block 302-21 fixedly connected thereto to move again. When the U-shaped rod 302-51 moves, it drives the third arc-shaped convex block 302-53 to move away from the pulverizing and filtering frame 302-1 through the second extrusion rod 302-52. The second arc-shaped convex block 302-43 in contact with it drives the fixed rod 302-41 to squeeze the return spring 302-45 again under the extrusion of the third arc-shaped convex block 302-53, and the return spring 302-45 is compressed. During the process of the return spring 302-45 being compressed, the fixed rod 302-41 drives the moving block 302-21 fixedly connected thereto to move again. The moving directions of the two moving blocks 302-21 are also opposite. Therefore, under mutual friction, the caked disinfection powder can be pulverized again. In such a cycle, the disinfection powder between a pair of moving blocks 302-21 is repeatedly rubbed back and forth, so as to thoroughly pulverize the caked disinfection powder, and the filtering efficiency can be improved.

10. The method for adding disinfectant powder to wastewater treatment according to any one of claims 1 to 9, characterized in that: It includes the following steps: Step 1: First, an appropriate amount of disinfection powder is added between a pair of moving blocks (302-21) of each crushing and filtering frame (302-1) through the material storage unit (200). Step 2: Then, start the driving motor (301). The output end of the driving motor (301) drives the turntable (301-5) to rotate clockwise. The turntable (301-5) drives the arc-shaped moving groove (301-9) to rotate accordingly. During the clockwise rotation of the arc-shaped moving groove (301-9), the inner wall of the arc-shaped moving groove (301-9) can exert a pulling force on the convex post (301-8). Thus, the push rod (301-7) can be pulled to move along the inside of the guiding sliding sleeve (301-4) through the convex post (301-8). The push rod (301-7) pulls the first extrusion rod (301-10) and the C-shaped rod (302-51) to move. Among them, the first extrusion rod (301-10) pulls the first arc-shaped convex block (301-11) to move away from the moving crushing and filtering frame (302-1). The second arc-shaped convex block (302-43) drives the fixed rod (302-41) to squeeze the return spring (302-45) under the extrusion of the first arc-shaped convex block (301-11), and the return spring (302-45) is compressed. During the process of the return spring (302-45) being compressed, the fixed rod (302-41) drives the moving block (302-21) fixedly connected to it to move. When the C-shaped rod (302-51) moves, it drives the third arc-shaped convex block (302-53) to move towards the crushing and filtering frame (302-1) through the second extrusion rod (302-52). The second arc-shaped convex block (302-43) in contact with it drives the fixed rod (302-41) to squeeze the return spring (302-45) under the extrusion of the third arc-shaped convex block (302-53), and the return spring (302-45) is compressed. During the process of the return spring (302-45) being compressed, the fixed rod (302-41) drives the moving block (302-21) fixedly connected to it to move. The moving directions of the two moving blocks (302-21) are opposite. Therefore, under mutual friction, the agglomerated disinfection powder can be preliminarily crushed. After being filtered by the filter mesh plate (302-22), the crushed disinfection powder and the non-agglomerated disinfection powder are added to the wastewater pool through the second material leakage port (302-23) and the first material leakage port (302-3). Step 3: After that, when the first arc-shaped convex block (301-11) and the third arc-shaped convex block (302-53) pass through the second arc-shaped convex block (302-43), the second arc-shaped convex block (302-43), the fixed rod (302-41) and the pair of moving blocks (302-21) move and reset under the resilience of the return spring (302-45). And during the reset process, the pair of moving blocks (302-21) can also further crush the agglomerated disinfection powder among them. Step 4: After that, after the moving block (302-21) is reset, the driving motor (301) drives the turntable (301-5) to rotate counterclockwise. The turntable (301-5) drives the arc-shaped moving groove (301-9) to rotate accordingly. During the counterclockwise rotation of the arc-shaped moving groove (301-9), the inner wall of the arc-shaped moving groove (301-9) can exert a driving force on the convex post (301-8). Thus, the push rod (301-7) can be pushed by the convex post (301-8) to move along the inside of the guiding sliding sleeve (301-4). The push rod (301-7) pushes the first extrusion rod (301-10) and the C-shaped rod (302-51) to move. Among them, the first extrusion rod (301-10) pushes the first arc-shaped convex block (301-11) to move towards the pulverizing and filtering frame (302-1). The second arc-shaped convex block (302-43) is extruded by the first arc-shaped convex block (301-11) to drive the fixed rod (302-41) to squeeze the reset spring (302-45) again, and the reset spring (302-45) is compressed. During the process of the reset spring (302-45) being compressed, the fixed rod (302-41) drives the moving block (302-21) fixedly connected thereto to move again. When the C-shaped rod (302-51) moves, it drives the third arc-shaped convex block (302-53) to move away from the pulverizing and filtering frame (302-1) through the second extrusion rod (302-52). The second arc-shaped convex block (302-43) in contact with it is extruded by the third arc-shaped convex block (302-53) to drive the fixed rod (302-41) to squeeze the reset spring (302-45) again, and the reset spring (302-45) is compressed. During the process of the reset spring (302-45) being compressed, the fixed rod (302-41) drives the moving block (302-21) fixedly connected thereto to move again. The moving directions of the two moving blocks (302-21) are also opposite. Therefore, under mutual friction, the caked disinfectant powder can be pulverized again. By repeating this cycle, the disinfectant powder between a pair of moving blocks (302-21) is repeatedly rubbed back and forth, so as to achieve the purpose of thoroughly pulverizing the caked disinfectant powder and improve the filtering efficiency.
