Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to an industrial wastewater treatment device with a telescopic mechanism. Background Art

[0002] The wastewater produced by the electrochemical industry generally contains a large amount of chemical ions and organic matter. For example, the wastewater from the electrolytic salt industry contains mercury, the wastewater from the heavy metal smelting industry contains various heavy metals such as lead and cadmium, the wastewater from the electroplating industry contains various heavy metals such as cyanide and chromium, and the wastewater from the petroleum refining industry contains phenol. These wastewaters contain a variety of toxic substances, which not only pollute the environment, but also have great harm to human health.

[0003] In the related art, the invention patent with announcement number CN112499805B discloses a mercury-contaminated industrial wastewater treatment device, and the key points of its technical solution are: comprising a shell: the bottom end of the shell cover cooperates with the top end of the shell, the liquid outlet pipe is arranged at the right end of the front side of the shell, the bottom end of the inside of the shell is provided with a filter unit, and the top end of the shell is provided with an adsorption unit; a stirring unit: comprising an electric telescopic rod, a fixed frame, a linear motor, a motor, a stirring plate and a rotating shaft, the linear motor is arranged on the rear side of the bottom end of the shell cover, the front side surface of the linear motor mover seat is provided with an electric telescopic rod, the front end of the electric telescopic rod is provided with a fixed frame, the inside of the fixed frame is provided with a motor, the output shaft of the motor is connected to the top end of the rotating shaft, the rotating shaft is located on the lower side of the fixed frame, and the outer side of the rotating shaft is arrayed with stirring plates.

[0004] Although the industrial wastewater treatment device disclosed in the above patent can remove heavy metal elements in wastewater, it still encounters the following problems during actual application: the heavy metal elements in the wastewater combine with the flocculant to form flocs, and then the flocs are intercepted by the filter unit, thereby playing a role in separating the heavy metal elements in the industrial wastewater. However, flocs usually have the characteristics of large volume and low density. That is to say, as the water flow to be treated continues to flow through the filter unit, the flocs will gradually gather around the filter holes under the action of the water flow, which will affect the efficiency of the water flow through the filter unit, that is, affect the effect of the device in treating wastewater.

[0005] In view of this, the present invention proposes an industrial wastewater treatment device with a telescopic mechanism to improve the deficiencies in the prior art. Summary of the invention

[0006] The present invention aims at the technical problems existing in the prior art and provides an industrial wastewater treatment device with a telescopic mechanism to solve the problem in the background art that flocculants gather around the filter holes, thereby affecting the water purification effect.

[0007] In order to solve the above-mentioned problems, the technical solution of the present invention is as follows: an industrial wastewater treatment device with a telescopic mechanism, comprising a treatment chamber installed on a wall, an outer mounting seat installed on the top of the treatment chamber, an inner mounting ring fixedly connected to the inner side wall of the treatment chamber, a stirring mechanism provided at the axis of the treatment chamber, a transfer mechanism provided at the upper part of the treatment chamber, the transfer mechanism comprising a fixed unit and a movable unit, the fixed unit of the transfer mechanism fixedly connected to the edge of the inner mounting ring, a telescopic unloading mechanism installed on one side of the movable unit of the transfer mechanism, the telescopic unloading mechanism fixedly connected to a toggle mechanism on a side away from the movable unit of the transfer mechanism, the toggle mechanism is coaxially connected to the stirring mechanism, and a filtering mechanism is provided below the inner mounting ring;

[0008] The treatment chamber is used to purify the industrial wastewater to be treated, the telescopic feeding mechanism is used to store the flocculant, the transfer mechanism is used to drive the telescopic feeding mechanism to move so as to change the position where the telescopic feeding mechanism spreads the flocculant, the stirring mechanism is used to stir the industrial wastewater flowing through the treatment chamber so that the flocculant is fully in contact with the industrial wastewater, and the filtering mechanism is used to intercept the floccules generated by the wastewater;

[0009] During the process of the stirring mechanism stirring the industrial wastewater, the toggle mechanism can drive the telescopic unloading mechanism to telescope and shake, so that the telescopic unloading mechanism can unload the material automatically;

[0010] The stirring mechanism can scrape off the flocculants on the top of the filtering mechanism, and the rotational lift of the stirring mechanism can dredge the filtering mechanism.

[0011] On the basis of the above technical solution, the present invention can also make the following improvements:

[0012] As a further improvement of the present technical solution, the stirring mechanism includes a main rod, a first motor and a fixed frame, the main rod and the first motor are respectively located on both sides of the outer mounting seat, the fixed frame is fixedly connected to the inner bottom wall of the processing chamber, the main rod is coaxially connected to the output shaft of the first motor, the bottom end of the main rod is rotatably connected to the fixed frame, and a plurality of stirring groups are coaxially connected to the periphery of the main rod.

[0013] As a further improvement of the technical solution, each of the stirring groups is located above the filtering mechanism, and the plurality of stirring groups are arranged in sequence from high to low. The stirring groups include a plurality of blades, and the shape of the blades is concave.

[0014] The beneficial effect of adopting the above-mentioned improvement scheme is that the first motor drives the main rod to rotate in the treatment chamber, and the main rod then drives the stirring group on its periphery to rotate, so as to evenly mix the flocculant and industrial wastewater falling into the treatment chamber.

[0015] As a further improvement of the technical solution, the fixed unit of the transfer mechanism includes a guide rail fixedly connected to the inner mounting ring, and the movable unit of the transfer mechanism includes a transfer seat, which is slidably connected to the top of the guide rail.

[0016] As a further improvement of the technical solution, the transfer seat is internally rotatably connected with a plurality of pulleys, each of which is connected to the guide rail wheel rail, and a second motor is provided on one side of one of the pulleys, and the output shaft of the second motor is coaxially connected to the pulley.

[0017] The beneficial effect of adopting the above-mentioned improvement scheme is that the second motor drives the pulley coaxially connected to its own output shaft to rotate, and under the action of the friction between the pulley and the guide rail (that is, the wheel-rail contact relationship), the transfer seat will drive the telescopic unloading mechanism to move along the guide rail. The telescopic unloading mechanism completes the unloading of the flocculant during the movement, thereby avoiding the flocculant being added at the same place in the treatment room for industrial wastewater at one time.

[0018] As a further improvement of the present technical solution, the telescopic unloading mechanism includes a mounting plate fixedly connected to the transfer seat, the mounting plate is fixedly connected to a plurality of pairs of limit bolts on a side away from the transfer seat, a sliding rod is fixedly connected between two limit bolts at the same height, the telescopic unloading mechanism also includes a medicine storage bin, the medicine storage bin is slidably connected to a plurality of sliding rods, a spring is provided between the outer wall of the medicine storage bin and each limit bolt, and each of the springs is sleeved on the outer periphery of the sliding rod.

[0019] As a further improvement of the present technical solution, the medicine storage bin includes a bin body, a material discharge slope is provided at the bottom of the bin body, a plurality of material discharge holes are opened at the bottom of the bin body, and each of the material discharge holes is located on the side with the lowest height of the material discharge slope.

[0020] The beneficial effect of adopting the above-mentioned improvement scheme is that when the medicine storage bin moves with the transfer seat, the toggle mechanism continuously toggle the outer wall of the medicine storage bin, so that the bin body slides on the slide rod, and at the same time, each spring is deformed, and the vibration amplitude of the external bin body is transmitted to the inside of the bin body, so that the flocculant inside the bin body will also slide down along the inclined discharge slope, and then pass through the discharge hole to fall into the treatment room and mix with industrial wastewater. When the medicine storage bin slides along the slide rod to the maximum displacement, the bin body will be reset under the action of the restoring force of each spring. In the process of the above-mentioned medicine storage bin repeatedly sliding and resetting on the slide rod, automatic and intermittent discharge of flocculants is realized.

[0021] As a further improvement of the present technical solution, the toggle mechanism includes a positioning ring and a plurality of first protrusions, the positioning ring is fixedly connected to the medicine storage bin, the positioning ring is sleeved on the periphery of the main rod, each of the first protrusions is fixedly connected to the main rod, and a plurality of second protrusions are fixedly connected to the inner wall of the positioning ring.

[0022] As a further improvement of the present technical solution, multiple first bumps are distributed in a circular array on the outer wall of the main rod, and multiple second bumps are distributed in a circular array on the inner wall of the positioning ring. The centroid of the first bump and the centroid of the second bump are located in the same height plane, and two adjacent first bumps and second bumps are staggered. The distance between the outer wall of the main rod and the inner wall of the positioning ring is smaller than the sum of the widths of the first bump and the second bump, and the angular velocity of the positioning ring is different from the angular velocity of the main rod.

[0023] The beneficial effect of adopting the above-mentioned improvement scheme is that, due to the difference in angular velocity of the main rod and the medicine storage bin rotating around the axis of the treatment chamber, the first protrusion and the second protrusion will not move synchronously, that is, the first protrusion and the second protrusion will continuously squeeze and staggered movement due to the difference in rotation speed, so the positioning ring will be continuously squeezed, and correspondingly, the medicine storage bin will be continuously shaken, so that the flocculant in the bin body will be continuously shaken off.

[0024] Furthermore, when the amount of industrial wastewater to be treated increases, it is necessary to appropriately increase the rotation speed of the main rod (i.e., increase the rotation speed of the first motor). As a result, the number of times the first and second protrusions are interlaced and squeezed per unit time will increase, i.e., the number of times the main rod moves the positioning ring per unit time will increase. In other words, when the amount of industrial wastewater to be treated in the treatment chamber is different, the amount of flocculant sprinkled from the drug storage bin into the treatment chamber can be automatically adjusted according to the change in the rotation speed of the main rod, without changing the output power of the second motor. Compared with changing the output power of the first and second motors at the same time, the above-mentioned adjustment method of only changing the output power of the first motor reduces the difficulty in coordination.

[0025] As a further improvement of the technical solution, the filtering mechanism includes an intercepting plate fixedly connected to the inner wall of the processing chamber, a plurality of filter holes are formed on the intercepting plate, and the top of the intercepting plate is close to the stirring group at the bottom.

[0026] The beneficial effect of adopting the above-mentioned improved solution is that when the main rod 210 is driven by the first motor to drive the blades to rotate, the blades at the bottom will scrape off the floccules on the top of the interception plate to prevent the floccules from blocking the filter holes and thus affecting the water flow efficiency of the interception plate. The concave blade structure design generates a lift when rotating, which can drive the floccules to gradually rise and prevent the floccules from blocking the filter holes.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. In the industrial wastewater treatment device with a telescopic mechanism, a treatment chamber is provided for purifying the industrial wastewater to be treated, a telescopic feeding mechanism is used for storing flocculants, a transfer mechanism is used for driving the telescopic feeding mechanism to move so as to change the position of the telescopic feeding mechanism for spreading the flocculants, a stirring mechanism is used for stirring the industrial wastewater flowing through the treatment chamber so as to make the flocculants fully contact with the industrial wastewater, and a filtering mechanism is used for intercepting floccules generated by the wastewater.

[0029] 2. In the industrial wastewater treatment device with a telescopic mechanism, during the process of the stirring mechanism stirring the industrial wastewater, the toggle mechanism can drive the telescopic feeding mechanism to telescope and shake, so that the telescopic feeding mechanism can automatically discharge the materials; the stirring mechanism can scrape off the flocculants on the top of the filtering mechanism, and the rotating lift of the stirring mechanism can dredge the filtering mechanism.

[0030] 3. In the industrial wastewater treatment device with a telescopic mechanism, when the amount of industrial wastewater flowing through the treatment chamber increases, it is necessary to appropriately increase the speed at which the stirring mechanism stirs the industrial wastewater. As a result, the number of times the toggle mechanism toggles the drug storage bin per unit time will increase. In other words, when the amount of industrial wastewater to be treated in the treatment chamber is different, the toggle mechanism can automatically adjust the amount of flocculant sprinkled from the drug storage bin into the treatment chamber.

[0052] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] See also Figure 1-Figure 4As shown, this embodiment provides an industrial wastewater treatment device with a telescopic mechanism, including a treatment chamber 100 installed on a wall, an outer mounting seat 110 is installed on the top of the treatment chamber 100, an inner mounting ring 120 is fixedly connected to the inner side wall of the treatment chamber 100, a stirring mechanism 200 is provided at the axis of the treatment chamber 100, a transfer mechanism 300 is provided at the upper part of the treatment chamber 100, the transfer mechanism 300 includes a fixed unit and a movable unit, the fixed unit of the transfer mechanism 300 is fixedly connected to the edge of the inner mounting ring 120, a telescopic unloading mechanism 400 is installed on one side of the movable unit of the transfer mechanism 300, the telescopic unloading mechanism 400 is fixedly connected to a toggle mechanism 500 on a side away from the movable unit of the transfer mechanism 300, the toggle mechanism 500 is coaxially connected to the stirring mechanism 200, and a filtering mechanism 600 is provided below the inner mounting ring 120;

[0054] The treatment chamber 100 is used to purify the industrial wastewater to be treated, the telescopic feeding mechanism 400 is used to store the flocculant, the transfer mechanism 300 is used to drive the telescopic feeding mechanism 400 to move so as to change the position where the telescopic feeding mechanism 400 spreads the flocculant, the stirring mechanism 200 is used to stir the industrial wastewater flowing through the treatment chamber 100 so as to make the flocculant fully contact with the industrial wastewater, and the filtering mechanism 600 is used to intercept the flocculants generated by the wastewater;

[0055] During the process of the stirring mechanism 200 stirring the industrial wastewater, the toggle mechanism 500 can drive the telescopic feeding mechanism 400 to telescope and shake, so that the telescopic feeding mechanism 400 can automatically discharge the materials; the stirring mechanism 200 can scrape off the flocculants on the top of the filtering mechanism 600, and the rotational lift of the stirring mechanism 200 can dredge the filtering mechanism 600.

[0056] Working principle:

[0057] First, the industrial wastewater to be treated is introduced into the treatment chamber 100, and then the power supply of the transfer mechanism 300 is turned on. The transfer mechanism 300 drives the telescopic feeding mechanism 400 to move to change the position of the telescopic feeding mechanism 400 to spread the flocculant. At the same time, the stirring mechanism 200 stirs the industrial wastewater flowing through the treatment chamber 100 so that the flocculant is fully in contact with the industrial wastewater. During this period, the floccules generated by the contact between the flocculant and the industrial wastewater will gradually sink to the top of the filtering mechanism 600 under the action of their own gravity.

[0058] During the process of the stirring mechanism 200 stirring the industrial wastewater, the toggle mechanism 500 drives the telescopic feeding mechanism 400 to telescope and shake, so that the flocculant in the telescopic feeding mechanism 400 is automatically discharged; and the stirring mechanism 200 can scrape off the flocculants on the top of the filtering mechanism 600, and the rotational lift generated by the operation of the stirring mechanism 200 can dredge the filtering mechanism 600 to prevent the filtering mechanism 600 from being blocked by the flocculants.

[0059] like Figure 5 As shown, the stirring mechanism 200 includes a main rod 210, a first motor 220 and a fixed frame 230. The main rod 210 and the first motor 220 are respectively located on both sides of the outer mounting seat 110. The fixed frame 230 is fixedly connected to the inner bottom wall of the processing chamber 100. The main rod 210 is coaxially connected to the output shaft of the first motor 220. The bottom end of the main rod 210 is rotatably connected to the fixed frame 230. A plurality of stirring groups 240 are coaxially connected to the periphery of the main rod 210.

[0060] Each stirring group 240 is located above the filtering mechanism 600 , and the plurality of stirring groups 240 are arranged in order from high to low. The stirring group 240 includes a plurality of blades, and the shape of the blades is concave.

[0061] It should be noted that after the first motor 220 is powered on, the first motor 220 drives the main rod 210 to rotate in the treatment chamber 100, and the main rod 210 then drives the stirring group 240 on its periphery to rotate, so as to evenly mix the flocculant and industrial wastewater that fall into the treatment chamber 100.

[0062] Compared with the conventional blades used for stirring, the advantages of using concave blades in this application are:

[0063] (1) Enhanced stirring effect. The concave blade can generate downward axial flow during the stirring process. When the blade rotates, it will push the wastewater and flocculant in the upper layer downward forcefully, so that the fluid in the entire stirring area forms an up-and-down circulation flow pattern. Compared with the plane blade, this flow pattern can more effectively avoid the stratification phenomenon that occurs during the stirring process. For example, when treating some industrial wastewater containing pollutants and flocculants with large density differences, the plane blade may only stir in a local area, resulting in the upper and lower layers of fluid not being fully mixed. The axial flow of the concave blade can make the wastewater and flocculant fully contact in the vertical direction, thereby improving the uniformity of mixing. For example, in the treatment of paper industry wastewater, the wastewater contains a large amount of fibers, fine particles and added flocculants. The concave blade can quickly transport the flocculant in the upper layer to the lower layer, so that the flocculant is fully mixed with the suspended matter and colloids in the wastewater, promoting the flocculation reaction.

[0064] (2) Improve flocculation efficiency. The special flow field generated by the concave blades is conducive to the growth and aggregation of floccules. Its downward axial flow can cause the flocculant and the suspended particles in the wastewater to collide and combine with each other in a relatively compact space. Under this flow field, the collision probability of suspended particles and flocculants increases, and due to the stability of the flow field, the small floccules that have been formed are not easily destroyed and can further grow and aggregate. For example, when treating wastewater from the printing and dyeing industry, the wastewater contains various dye molecules and auxiliaries. The concave blades can make the flocculant fully mix with these pollutants, accelerate the formation of floccules, and make the floccules reach the required size for sedimentation or floating more quickly. Application scenario: When treating electroplating industrial wastewater containing heavy metal ions, the stirring method of the concave blades can make heavy metal floccules form and grow better. The floccules generated by the reaction of flocculants (such as sodium sulfide or polyferric sulfate, etc.) with heavy metal ions can settle faster under this efficient stirring, thereby improving the efficiency of wastewater treatment.

[0065] (3) Reduce energy loss. While producing an effective stirring effect, the concave blades have relatively less resistance during rotation compared to some other complex-shaped blades. This is because the design of the concave blades allows the fluid to flow more smoothly around the blades, reducing the formation of vortices. When the blades rotate, vortices consume a lot of energy, and the concave blades can guide the fluid to flow in a more orderly manner, thereby reducing energy loss. For example, in large-scale industrial wastewater treatment plants, a large amount of wastewater needs to be processed every day, and the stirring process consumes a lot of electricity. The use of concave blades can reduce the power of the stirring motor while ensuring the stirring effect, thereby saving energy and reducing treatment costs.

[0066] exist Figure 6 and Figure 7 In the embodiment, the fixed unit of the transfer mechanism 300 includes a guide rail 310 fixedly connected to the inner mounting ring 120 , and the movable unit of the transfer mechanism 300 includes a transfer seat 320 , which is slidably connected to the top of the guide rail 310 .

[0067] Furthermore, the transfer seat 320 is internally rotatably connected with a plurality of pulleys 330 , each pulley 330 is connected to the wheel rail of the guide rail 310 , a second motor 340 is provided on one side of one pulley 330 , and an output shaft of the second motor 340 is coaxially connected to the pulley 330 .

[0068] After the power of the second motor 340 is turned on, the second motor 340 drives the pulley 330 coaxially connected to its own output shaft to rotate. Under the action of the friction force between the pulley 330 and the guide rail 310 (i.e., the wheel-rail contact relationship), the transfer seat 320 will drive the telescopic unloading mechanism 400 to move along the guide rail 310. The telescopic unloading mechanism 400 completes the unloading of the flocculant during the movement, thereby avoiding the flocculant being added to the same place of the industrial wastewater in the treatment chamber 100 at one time.

[0069] like Figure 8-Figure 10 As shown, the telescopic feeding mechanism 400 includes a mounting plate 410 fixedly connected to the transfer seat 320, and a plurality of pairs of limit bolts 420 are fixedly connected to the mounting plate 410 on a side away from the transfer seat 320, and a slide rod 430 is fixedly connected between two limit bolts 420 located at the same height, and the telescopic feeding mechanism 400 also includes a medicine storage bin 440, which is slidably connected to a plurality of slide rods 430, and a spring 450 is provided between the outer wall of the medicine storage bin 440 and each limit bolt 420, and each spring 450 is sleeved on the outer periphery of the slide rod 430.

[0070] Specifically, the medicine storage bin 440 includes a bin body 441 , a material discharge slope 442 is provided at the bottom of the bin body 441 , and a plurality of material discharge holes 443 are opened at the bottom of the bin body 441 , and each material discharge hole 443 is located on the side of the material discharge slope 442 with the lowest height.

[0071] When the medicine storage bin 440 moves with the transfer seat 320, the toggle mechanism 500 continuously toggle the outer wall of the medicine storage bin 440, so that the bin body 441 slides on the slide bar 430 (i.e. deviates from the original position), and at the same time, each spring 450 is deformed, and the vibration amplitude of the external vibration of the bin body 441 is transmitted to the inside of the bin body 441, so that the flocculant inside the bin body 441 will also slide down along the inclined discharge slope 442, and then pass through the discharge hole 443 and fall into the treatment chamber 100 to mix with industrial wastewater. When the medicine storage bin 440 slides along the slide bar 430 to the maximum displacement, the bin body 441 will be reset under the action of the restoring force of each spring 450. In the process of the medicine storage bin 440 repeatedly sliding and resetting on the slide bar 430, the automatic and intermittent discharge of the flocculant is realized.

[0072] like Fig.11 and Fig.12 As shown, the toggle mechanism 500 includes a positioning ring 510 and a plurality of first protrusions 520 . The positioning ring 510 is fixedly connected to the medicine storage bin 440 . The positioning ring 510 is sleeved on the periphery of the main rod 210 . Each first protrusion 520 is fixedly connected to the main rod 210 . A plurality of second protrusions 530 are fixedly connected to the inner wall of the positioning ring 510 .

[0073] It should be noted that multiple first bumps 520 are distributed in a circular array on the outer wall of the main rod 210, and multiple second bumps 530 are distributed in a circular array on the inner wall of the positioning ring 510. The centroid of the first bump 520 and the centroid of the second bump 530 are located in the same height plane, and two adjacent first bumps 520 and second bumps 530 are staggered. The distance between the outer wall of the main rod 210 and the inner wall of the positioning ring 510 is less than the sum of the widths of the first bump 520 and the second bump 530, and the angular velocity of the positioning ring 510 is different from the angular velocity of the main rod 210.

[0074] Since there is a difference in the angular velocity of the main rod 210 and the drug storage bin 440 rotating around the axis of the treatment chamber 100, for example, the angular velocity of the main rod 210 is greater than the angular velocity of the circular motion of the drug storage bin 440 (or the angular velocity of the main rod 210 is also smaller than the angular velocity of the drug storage bin 440), then the first protrusion 520 and the second protrusion 530 will not move synchronously, that is, the first protrusion 520 and the second protrusion 530 will continuously squeeze and staggered motion due to the difference in rotation speed, so that the positioning ring 510 will be continuously squeezed, and correspondingly, the drug storage bin 440 will be continuously shaken, so that the flocculant in the bin body 441 will be continuously shaken out.

[0075] Furthermore, when the amount of industrial wastewater to be treated increases, it is necessary to appropriately increase the rotation speed of the main rod 210 (i.e., increase the rotation speed of the first motor 220). Therefore, the number of times the first protrusion 520 and the second protrusion 530 are interlaced and squeezed per unit time will increase, i.e., the number of times the main rod 210 moves the positioning ring 510 per unit time will increase. In other words, when the amount of industrial wastewater to be treated in the treatment chamber 100 is different, the amount of flocculant sprinkled into the treatment chamber 100 by the drug storage bin 440 can be automatically adjusted according to the change in the rotation speed of the main rod 210, without changing the output power of the second motor 340. Compared with simultaneously changing the output power of the first motor 220 and the second motor 340, the above-mentioned adjustment method of only changing the output power of the first motor 220 reduces the difficulty in coordination.

[0076] Based on the above description, combined with Fig.13 and Fig.14 The preferred effects of the stirring mechanism 200 and the filtering mechanism 600 are explained. The filtering mechanism 600 includes an intercepting plate 610 fixedly connected to the inner wall of the processing chamber 100. A plurality of filter holes 620 are provided on the intercepting plate 610. The top of the intercepting plate 610 is close to the stirring group 240 at the bottom.

[0077] Therefore, when the main rod 210 is driven by the first motor 220 to drive the blades to rotate, the blades at the bottom will scrape off the flocculants on the top of the intercepting plate 610 to prevent the flocculants from blocking the filter holes 620 and thus affecting the water flow efficiency of the intercepting plate 610.

[0078] In addition, the concave blade structure design can generate a lift when rotating, which can drive the flocculants to gradually rise and prevent the flocculants from being blocked in the filter hole 620.

[0079] The working principle of the present invention is as follows:

[0080] First, the industrial wastewater to be treated is introduced into the treatment chamber 100, and then the second motor 340 drives the pulley 330 coaxially connected to its own output shaft to rotate. Under the action of the friction between the pulley 330 and the guide rail 310, the transfer seat 320 will drive the drug storage bin 440 to move along the guide rail 310. The drug storage bin 440 completes the unloading of flocculant during the movement, thereby avoiding the flocculant being added to the same place of the industrial wastewater in the treatment chamber 100 at one time.

[0081] At the same time, the first motor 220 drives the main rod 210 to rotate in the treatment chamber 100, and the main rod 210 drives the stirring group 240 on its periphery to rotate, so as to evenly mix the flocculant and industrial wastewater falling into the treatment chamber 100.

[0082] During this period, flocculants generated by the contact between the flocculant and the industrial wastewater will gradually sink to the top of the interception plate 610 under the action of their own gravity.

[0083] During the process of the blades stirring the industrial wastewater, when the medicine storage bin 440 moves with the transfer seat 320, the main rod 210 continuously moves the outer wall of the medicine storage bin 440, so that the bin body 441 slides on the slide bar 430 (i.e. deviates from the original position), and at the same time, each spring 450 is deformed, and the vibration amplitude of the external vibration of the bin body 441 is transmitted to the inside of the bin body 441, so that the flocculant inside the bin body 441 will also slide down along the inclined discharge slope 442, and then pass through the discharge hole 443 and fall into the treatment chamber 100 to mix with the industrial wastewater. When the medicine storage bin 440 slides along the slide bar 430 to the maximum displacement, the bin body 441 will be reset under the action of the restoring force of each spring 450. In the process of the medicine storage bin 440 repeatedly sliding and resetting on the slide bar 430, the automatic and intermittent discharge of the flocculant is realized.

[0084] When the main rod 210 is driven by the first motor 220 to drive the blades to rotate, the blades at the bottom scrape off the floccules on the top of the interception plate 610 to prevent the floccules from blocking the filter holes 620, thereby affecting the water flow efficiency of the interception plate 610. In addition, the concave blade structure design generates a lift when rotating, which can drive the floccules to gradually rise and prevent the floccules from blocking the filter holes 620.
