Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to an alum throwing device for an industrial sewage treatment pool and an operating method thereof. Background Art

[0002] Industrial wastewater refers to wastewater and waste liquid discharged during the process of production, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. It is an important cause of environmental pollution, especially water pollution. In order to protect the ecological environment and reduce the damage caused by industrial wastewater to the environment, the wastewater generated in the industrial production process needs to be treated accordingly; Using alum to treat sewage is a common treatment method now. Alum, as a common water purification agent, has a strong adsorption effect. When treating sewage, alum can adsorb colloids, suspended matter and organic matter in sewage, float them up, and finally settle to the bottom, achieving a higher purification effect. The input of alum can be achieved by using a throwing device. For example, the existing public document CN114349140A-A sewage treatment pool alum throwing device for sewage treatment discloses an alum throwing device; Although the existing alum throwing device for industrial sewage treatment pools can realize the throwing operation, it still has certain shortcomings in actual use: first, the existing sewage treatment pool alum throwing equipment is driven by a motor to rotate the receiving box to throw the alum inside it, and this method has a certain power of the motor when in use, and cannot be adjusted accordingly according to the distance of the alum throwing and the amount of alum in the receiving box. The scope of application is small, and the structure is complex, and subsequent maintenance work is more difficult; secondly, the existing sewage treatment pool alum throwing equipment controls the alum output through a solenoid valve or a discharging device when in use, and this method will increase the control system, power consumption, etc. At the same time, the resistance block in the discharging device needs to rotate synchronously when the receiving box rotates to push the L-shaped slide bar to move, so that the arc baffle opens down The alum cannot fall into the receiving box, resulting in a waste of alum and the inability to control the amount of throwing. Finally, the existing sewage treatment pool alum throwing equipment uses steel balls, elastic impact rods, air bags and the like in the receiving box to clean the alum attached to the inner wall of the receiving box. When the steel balls are moved by inertia, they will have a certain impact force on the internal structure and inner wall of the receiving box, which will affect the service life of the receiving box and its internal structure. At the same time, the internal structure of the receiving box is complicated, which will affect the carrying capacity of the receiving box, resulting in low throwing efficiency and increased pressure on the driving equipment. Therefore, it is necessary to improve the existing technology to solve the above technical problems. Summary of the invention

[0037] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 , which is the first embodiment of the present invention, and provides an alum throwing device for an industrial sewage treatment pool. The alum throwing device for an industrial sewage treatment pool can adjust the throwing distance and throwing amount of alum powder by adjusting the number of the first tension springs 206, and has a wide range of applications.

[0038] Specifically, the base 100 has a frame plate 101 installed on one side of the upper surface of the base 100, and a middle partition 105 is installed in the middle of the other side of the upper surface of the base 100. An arc groove 105a is opened on one side of the middle partition 105, and a first electromagnetic block 105b is embedded in the top of the arc groove 105a. The front and rear ends of the middle partition 105 are respectively installed with a first bracket 106 and a second bracket 107. The tops of the first bracket 106 and the second bracket 107 are both rotatably installed with a seesaw. 108; and, a force adjustment assembly 200, comprising a moving plate 201 installed at one end of the seesaw 108 and a connecting column 202 fixedly connected to the center position of a side wall of the moving plate 201, the other end of the connecting column 202 is fixedly connected to a slider 203, the interior of the moving plate 201 is slidably connected to arc-shaped guide rods 204 at uniform intervals in the horizontal direction at the front and rear sides, the other end of the arc-shaped guide rods 204 is fixed to the inner wall of the support plate 205, and the outer wall of the arc-shaped guide rods 204 is sleeved with a first tension spring 206.

[0039] For details, please refer to Figure 7 and Figure 8One end of the first tension spring 206 is fixedly connected to a moving sleeve 207, and both sides of the moving sleeve 207 are provided with through slots 207a, and a fixed plate 208 is fixedly provided at the center of the inner wall of the through slot 207a, and a two-way telescopic rod 209 is installed at the center of the fixed plate 208. The two ends of the two-way telescopic rod 209 pass through the ports on both sides of the through slot 207a and are connected to the card plate 2010, and the two sides of the outer wall of the two-way telescopic rod 209 are sleeved with springs 211; wherein, the moving plate The front and rear sides of the surface of 201 are evenly spaced along the horizontal direction with clamping holes 201a, the interior of the slider 203 is embedded with an iron block 203a, the slider 203 is slidably connected inside the arc groove 105a, the other end of the first tension spring 206 is fixed on the inner wall of the support plate 205, the bottom end of the support plate 205 is fixed on the surface of the base 100, the spring 2011 is located between the fixed plate 208 and the adjacent clamping plate 2010, and the iron block 203a is magnetically attracted to the first electromagnetic block 105b; When the above arrangement is used, alum is first put into the pulverizing mechanism 102 for pulverization, and the pulverized powder falls into the upper vibration plate 103. After the upper vibration plate 103 vibrates and sieves, the coarse material falls into the upper vibration plate 103, and the fine material falls from the sieve holes on the upper vibration plate 103 to the lower vibration plate 104 below. Then, the coarse material and the fine material respectively pass through the coarse material pipe 103a and the fine material pipe 104a and fall into the corresponding material receiving box 109 below. After the alum powder falls into the material receiving box 109, the power supply to the first electromagnetic block 105b is stopped. At this time, the magnetic attraction effect of the first electromagnetic block 105b on the iron block 203a inside the slider 203 is stopped. The result disappears, and in this process, the moving plate 201 will always pull the first tension spring 206, so after the magnetic attraction force of the moving plate 201 disappears, the elastic performance of the first tension spring 206 pulls the moving plate 201 to slide along the outer wall of the arc guide rod 204, and the moving plate 201 makes a circular motion, which will cause the receiving box 109 at the other end to move upward under the action of the seesaw 108, and throw the powder in the receiving box 109 into the industrial sewage treatment pool. When it is necessary to adjust the distance and amount of powder throwing, the staff can manually push the card plates 2010 on both sides of the moving sleeve 207 toward the middle of the moving sleeve 207, and the card plates 2010 are stressed. By moving and squeezing the bidirectional telescopic rod 209 and the spring 2011 on its outer wall, the clamping plates 2010 on both sides of the movable sleeve 207 will move under the guidance of the bidirectional telescopic rod 209. At this time, the clamping plates 2010 can be moved out or inserted into the corresponding clamping holes 201a on the moving plate 201. By changing the number of movable sleeves 207 installed on the moving plate 201, the number of first tension springs 206 can be adjusted, and then the instantaneous kinetic energy and force generated by the moving plate 201 when throwing can be changed, so as to achieve the purpose of changing and adjusting the throwing distance and throwing amount of the powder. This method is convenient to operate, simple in structure, and easy for subsequent maintenance. The weight of the overall device is reduced, which is convenient for moving and throwing, and the instantaneous kinetic energy generated is greater than that of the motor drive, which is convenient for quickly throwing the powder. At the same time, corresponding adjustments can be made according to the throwing distance and throwing amount of the powder. It has a wide range of applications. After the number of connections of the first tension spring 206 is adjusted, the first electromagnetic block 105b is energized, and magnetic attraction is generated between the first electromagnetic block 105b and the iron block 203a in the slider 203, so that the slider 203 makes an upward circular arc motion in the arc groove 105a, and drives the moving plate 201 to move synchronously through the connecting column 202, so that the seesaw 108 is placed horizontally, and the above throwing operation is repeated.

[0040] Furthermore, the first bracket 106 and the second bracket 107 have the same structure and size. The cross-section of the first bracket 106 and the second bracket 107 is Y-shaped. The seesaw 108 rotates with its center position as the center of a circle when subjected to force. The arc guide rod 204 guides the moving plate 201. The cross-section of the support plate 205 is L-shaped. Under the elastic action of the first tension spring 206, the moving plate 201 is driven to move. The movable sleeve 207 is slidably sleeved on the outer wall of the arc guide rod 204. The bidirectional telescopic rod 209 is installed in the through groove 207a through the fixed plate 208. The position of the clamping plate 2010 can be adjusted under the elastic performance of the spring 2011. The clamping plate 2010 is L-shaped and can be clamped on the clamping hole 201a to limit the movable sleeve 207.

After the second electromagnetic block 301a is energized, it will be adsorbed together with the iron sheet 109b on the outer wall of the receiving box 109, so that the seesaw 108 will move synchronously with the synchronous frame 301 when rotating counterclockwise, and the synchronous frame 301 will move downward under the limiting action of the cross handle 302 and the limiting plate 303. The downward movement of the synchronous frame 301 will push the piston 302a along the inner wall of the gas cylinder 304 under the action of the cross handle 302, and when the piston 302a moves synchronously, the second tension spring 305 will be stretched, and at the same time, the gas in the gas cylinder 304 is affected After being squeezed, the raw materials are discharged from the first air pipe 304a, and then enter the corresponding air cylinder 402 through the first connecting pipe 304b, the second connecting pipe 304c and the second air pipe 402a respectively.

At this time, the ports of the coarse material tube 103a and the fine material tube 104a are opened, and the powder on the upper vibration plate 103 and the lower vibration plate 104 will fall into the corresponding material receiving box 109.

[0045] Furthermore, the synchronous frame 301 can move synchronously with the receiving box 109 under the magnetic attraction of the second electromagnetic block 301a and the iron sheet 109b, wherein the receiving box 109 makes a circular motion, and the synchronous frame 301 moves up and down under the guidance of the cross handle 302 and the limit plate 303, and the piston 302a can move in the gas cylinder 304, wherein the gas in the gas cylinder 304 and the gas in the cylinder 402 circulate under the action of the pipeline to realize gas flow, and the second tension spring 305 can be hung and disassembled through the hook 305a and the fixing ring 303a. Example 3

[0046] Reference Figure 6 and Fig.13 , which is the third embodiment of the present invention, is based on the above-mentioned embodiment 1, and the difference is that in order to prevent the alum powder from adhering to the inner wall of the receiving box 109, the inertia is used to drive the shovel plate 501 to move and shovel the attached powder off, thereby reducing waste and increasing the carrying capacity of the receiving box 109.

[0047] Specifically, it also includes a shovel bottom assembly 500 arranged inside the movable groove 108a and the storage groove 109a, and the shovel bottom assembly 500 includes a shovel plate 501 movably arranged inside the storage groove 109a and a movable rod 502 fixedly connected to the center position of one side wall of the shovel plate 501, the other end of the movable rod 502 sequentially penetrates the through hole on the inner wall of the storage groove 109a and the outer port of the movable groove 108a and is movably connected to the second connecting rod 503 through a hinge, and the other end of the second connecting rod 503 is fixedly provided with a limit block 504, and the center position of the other side end surface of the limit block 504 is embedded with a second magnetic plate 504a; wherein, the second magnetic plate 504a is magnetically attracted to the first magnetic plate 108b; When the above arrangement is in use, during the process of throwing the powder inside the receiving box 109, the shovel plate 501 inside it will be moved out of the storage groove 109a by the inertial force, and the shovel plate 501 will move synchronously along the inner wall of the movable groove 108a with the limit block 504 through the movable rod 502, the hinge and the second connecting rod 503. During this process, the shovel plate 501 will move along the bottom end of the inside of the receiving box 109, and shovel the powder attached to the bottom end of the inside of the receiving box 109 and throw it into the processing pool at the same time. After the powder inside the receiving box 109 is thrown out, the shovel plate 501 will automatically fall into the storage groove 109a under the action of gravity, and the second magnetic plate 504a embedded in the limit block 504 is adsorbed together with the first magnetic plate 108b on the inner wall of the movable groove 108a, so that the shovel plate 501 can be stabilized in the storage groove 109a without being subjected to external force, thereby preventing it from moving out and affecting the powder carrying capacity.

[0048] Furthermore, the cross-section of the shovel plate 501 is set to be trapezoidal, which is convenient for shoveling off the attached powder. The movable rod 502 and the second connecting rod 503 are movably connected by a hinge. When the shovel plate 501 contacts the inner wall of the material receiving box 109, it can rotate upward to reduce the loss of the material receiving box 109 body and increase the service life. The magnetic attraction between the first magnetic plate 108b and the second magnetic plate 504a is used to keep the shovel plate 501 stable. Example 4
