Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection water treatment, in particular to a solid-liquid dual-purpose water pollution treatment dosing device. Background Technique

[0002] When treating water pollution, a dosing device is needed to treat water pollution.

[0004] When dosing water pollution, liquids and solids (dry powder) can be added. However, first, for the dosing device, whether it is a liquid or a solid, the liquid or solid is added to the tank body and stirred with water, and finally added to the sewage in the form of a liquid for treatment. When directly adding solids to sewage, it is still carried out in the form of manual spreading. Of course, for some large enterprises with replacement funds, professional dry powder dosing devices will also be used, but each time it is used, the dosing device needs to be replaced with a solid dosing device, which is relatively troublesome and costly.

Detailed implementation mode

[0031] Regarding the foregoing and other technical contents, features and effects of the present utility model, they will be clearly presented in the following detailed description of the embodiments in conjunction with the attached Figures 1 to 6 drawings. The contents mentioned in the following embodiments are all referenced to the drawings of the specification.

[0032] The following will describe the exemplary embodiments of the present utility model with reference to the drawings.

[0033] The present utility model is a solid-liquid dual-purpose water pollution treatment chemical dosing device, mainly used for sewage treatment, adding a dissolved flocculant solution to sewage. The current chemical dosing devices can only add solutions and cannot add solids (dry powder). Here, although the flocculants added during chemical dosing, such as PAC, PAM, etc., are dry powder, they are all premixed with water to obtain a solution and then added to the sewage. Ultimately, the added is in liquid form.

[0034] The present utility model is improved on the basis of the existing chemical dosing devices. The existing chemical dosing devices are divided into single-tank, double-tank, multi-tank, etc. Mainly, different flocculants are added according to the actual needs of the sewage, which can be solids or liquids, and ultimately all become liquid forms for addition. For directly adding solids (dry powder) to sewage, most are manually sprinkled, and some use equipment, but the chemical dosing device needs to be specifically replaced with a dry powder dosing device, which increases the cost, wastes time for each replacement, and is troublesome to operate.

[0035] The utility model includes a bracket 1 for providing an installation foundation. A control box 2 is installed on the bracket 1 for automatically controlling subsequent electronic components. The control box 2 is connected to an external power supply. A tank body 3 is placed inside the bracket 1, which is mainly used for preparing a liquid medicine solution and then adding it to sewage. The upper end of the tank body 3 is connected to a water inlet pipe 4, a chemical dosing pipe 5, and a sewage discharge pipe 6. The water inlet pipe 4 is used to add tap water into the tank body 3. The chemical dosing pipe 5 is used to add the prepared solution into the sewage. The sewage discharge pipe 6 is used to drain the solution at the bottom of the tank body 3 when not in use. Solenoid valves, manual valves, metering pumps, filters, safety valves, backpressure valves, buffers, etc. required are also installed on the water inlet pipe 4, the chemical dosing pipe 5, and the sewage discharge pipe 6. A stirrer 7 is rotatably installed inside the tank body 3. The stirrer 7 is connected to a stirring motor 8 placed on the tank body 3 for stirring the solution inside the tank body 3. The stirring motor 8 is connected to a controller. A liquid level gauge is provided on the side wall of the tank body 3. A chemical dosing port for flocculant is opened at the upper end of the tank body 3.

[0036] An installation plate 9 is fixedly installed by extending on one side of the bracket 1 for providing an installation foundation. A feeding cylinder 10 is fixed on the installation plate 9 for feeding. The lower end of the feeding cylinder 10 is connected to a distributing cylinder 11. A rotating seat is fixed in the middle of the lower end of the distributing cylinder 11. A distributing plate 13 is rotatably installed inside the rotating seat. A sealing gasket is installed at the end of the distributing plate 13. The lower end of the distributing plate 13 is coaxially connected to a distributing motor 14 placed outside. A proximity switch or a travel switch is installed at the position of the distributing plate 13. The proximity switch or the travel switch and the distributing motor 14 are connected to the control box 2.

[0037] The lower end of the distributing cylinder 11 is bifurcated and connected to two symmetrical distributing pipes 12. A spiral conveyor rod 15 is horizontally rotatably installed inside each distributing pipe 12. The other end of each spiral conveyor rod 15 penetrates through the distributing pipe 12 and a lower bevel gear 16 is sleeved at the end. A support seat and a sealing gasket are installed at the junction. An upper bevel gear 17 that can slide is meshed above the lower bevel gear 16. The upper bevel gear 17 is coaxially connected to a conveyor rod motor 18. The conveyor rod motor 18 is fixed on a motor plate. The conveyor rod motor 18 is connected to the control box 2.

[0038] The dry flocculant to be added is added into the feeding cylinder 10. One of the lower distributing cylinders 11 is placed above the chemical dosing port of the dosing device, and the other is connected to or directly placed above the sewage for directly adding to the sewage.

[0039] When it is necessary to add to one of the distributing pipes 12, the distributing motor 14 is controlled to start, driving the distributing plate 13 to rotate. When the distributing plate 13 touches the side wall of the distributing cylinder 11, the distributing plate 13 stops rotating. At this time, the distributing pipe 12 at this place is closed, and the other distributing pipe 12 is connected. The flocculant falls into the distributing pipe 12 and is pushed forward by the rotation of the spiral conveyor rod 15.

[0040] The rotation of the spiral conveying rod 15 is to slide the corresponding upper bevel gear 17 to the corresponding position to engage with the lower bevel gear 16. The conveying rod motor 15 drives the upper bevel gear 17, and the upper bevel gear 17 engages with the lower bevel gear 16 to drive the spiral conveying rod 15 to rotate.

[0041] Furthermore, in order to realize the sliding and limiting of the upper bevel gear 17, a conveying rod motor plate 19 is fixed between the two material distribution pipes 12. A sliding hole 20 is opened in the middle of the conveying rod motor plate 19. A sliding block 21 is slidably installed in the sliding hole 20. Specifically, sliding grooves are opened on the two side walls of the sliding hole 20, and sliders matching the sliding grooves are fixed on the two side walls of the sliding block 21, so as to realize the sliding of the sliding block 21 in the sliding hole 20. An axially penetrating hole is opened in the sliding block 21. The motor shaft of the conveying rod motor 18 passes through the axially penetrating hole and is connected with the upper bevel gear 17. The upper bevel gear 17 is placed below the conveying rod motor plate 19, and the conveying rod motor 18 is placed above the conveying rod motor plate 19. The height of the sliding block 21 exceeds the sliding hole 20, and an L-shaped limiting plate 22 is fixed on the exceeding part. The end of the limiting plate 22 is placed on the side wall of the conveying rod motor plate 19. A limiting groove 23 is opened on the side wall of the conveying rod motor plate 19, and limiting holes are opened at both ends of the limiting groove 23. The position of each limiting hole is the position for engaging with the two lower bevel gears 16. A penetrating hole is opened at the end of the limiting plate 22, and a limiting pin 24 matching the limiting hole is slidably penetrated in the penetrating hole.

[0042] When it is necessary to slide the upper bevel gear 17 for switching, slide the limiting plate 22. The limiting plate 22 drives the upper bevel gear 17 and the conveying rod motor 18 to slide in the sliding hole 20. When sliding to the end, insert the limiting pin 24 into the limiting hole. At this time, the limiting plate 22 is locked to limit the upper bevel gear 17. The conveying rod motor 18 and the upper bevel gear 17 can normally engage with the lower bevel gear 16. On the contrary, pull out the limiting pin 24 and then move the limiting plate 22 to the other side for limiting, so as to complete the engagement with the other lower bevel gear 16.

[0043] Furthermore, in order to eliminate manual feeding, a feeding cylinder 26 placed below is connected to the side wall of the feeding cylinder 10 through a feeding pipe 25 and a feeding valve. The feeding cylinder 26 is provided with a measuring device or a weighing device or a timer, etc. The feeding cylinder 26 is a conical barrel. The feeding pipe 25 is connected to the lower end of the feeding cylinder 26. A vacuum pump 28 is also connected to the side wall of the feeding cylinder 10 through a vacuum pipe 27 and a pneumatic valve. The measuring device, the feeding valve, the pneumatic valve, and the vacuum pump 28 are connected to the control box 2.

[0044] The vacuum pump 28 forms a negative pressure in the feeding cylinder 10, and then feeds the material into the feeding cylinder 26 through the negative pressure via the feeding pipe 25.

[0045] Furthermore, to prevent dampness and caking from affecting the dissolution rate, a crushing cylinder 29 is installed between the feeding cylinder 10 and the material distributing cylinder 11. Two relatively meshing crushing rollers 30 are rotatably installed in the crushing cylinder 29. The end of each crushing roller 30 is sleeved with a gear that meshes with each other. One of the gears is coaxially connected to an external crushing motor 31. The crushing motor 31 is fixed outside the crushing cylinder 29 via a motor plate, and the crushing motor 31 is connected to the control box 2.

[0046] The crushing motor 31 drives one gear and the crushing roller 30 to rotate. The gear meshes with the other gear and the crushing roller 30 to rotate, so as to realize the caking crushing of the dry powder by the two crushing rollers 30, prevent the dry powder from caking, and improve the subsequent dissolution efficiency.

[0047] Furthermore, to achieve the sealing and feeding of the feeding cylinder 10, a sealing disc 32 is fixed at the lower end of the feeding cylinder 10. A plurality of feeding holes 33 are formed in the sealing disc 32. A rotating disc 34 is also rotatably installed at the lower end of the sealing disc 32. A docking hole 35 corresponding to the feeding hole 33 is formed in the rotating disc 34.

[0048] When the rotating disc 34 rotates a certain angle, the docking hole 35 is aligned with the feeding hole 33, and feeding can be realized. When the rotating disc 34 rotates a certain angle, the feeding hole 33 is blocked by the rotating disc 34, and the docking hole 35 is blocked by the sealing disc 32, achieving sealing.

[0049] Furthermore, to facilitate the sealing and feeding of the feeding cylinder 10, the rotation of the rotating disc 34 is specifically that a rotating shaft 36 is rotatably installed in the feeding cylinder 10. The rotating shaft 36 is rotatably connected to the sealing disc 32, so that when the rotating shaft 36 rotates, the sealing disc 32 remains stationary. The rotating shaft 36 is movably connected to the rotating disc 34, so that when the rotating shaft 36 rotates, it drives the rotating disc 34 not to rotate together. An arc-shaped groove 37 is formed on the lower end surface of the sealing disc 32. A sliding shaft 38 is fixed on the upper end surface of the rotating disc 34. The sliding shaft 38 matches the arc-shaped groove 37. An annular groove 39 is also formed on the lower end surface of the rotating disc 34. A plurality of blocking blocks 40 are fixedly installed at intervals in the annular groove 39. Both sides of the blocking block 40 are arc-shaped. A push rod 41 placed below the rotating disc 34 is fixed at the end of the rotating shaft 36. A spring housing 42 facing the rotating disc 34 is fixed at the end of the push rod 41. A spring is installed in the spring housing 42. The other end of the spring is connected to a push column 43. The end surface of the push column 43 is arc-shaped. The push column 43 can be compressed in the spring housing 42. The push column 43 is placed in the annular groove 39.

[0050] Assume that initially, the blanking hole 33 is aligned with the docking hole 35 to achieve blanking. When closing, the rotating shaft 36 rotates, driving the push rod 41 to rotate. The push rod 41 drives the push column 43 to rotate within the annular groove 39. When the push column 43 contacts the blocking block 40, it drives the entire rotating disk 34 to rotate, causing the sliding shaft 38 to slide within the arc-shaped groove 37. When the sliding shaft 38 slides to the end of the arc-shaped groove 37, at this time, the blanking hole 33 is misaligned with the docking hole 35, completing the sealing. The sliding shaft 38 is stuck at the arc-shaped groove 37 and cannot continue to rotate, and the rotating disk 34 stops. When the rotating disk 34 cannot continue to rotate, the push column 43 is compressed into the spring housing 42 under the action of the blocking block 40 and the spring in the annular groove 39, enabling the push column 43 to rotate selflessly over the blocking block 40. On the contrary, when blanking is required, reverse rotation of the rotating shaft 36 can achieve it.

[0051] Further, to achieve the rotation of the rotating shaft 36, a rotating motor 44 is connected above the rotating shaft 36. The rotating motor 44 is placed above the feeding cylinder 10. The rotating motor 44 is connected to the control box 2. The rotation of the rotating shaft 36 can be equipped with a timer, an angle sensor, a limiter, a travel switch, etc. according to requirements. To further prevent the flocculant from caking, when the feeding cylinder 10 is closed for feeding, a plurality of stirring rollers 45 are sleeved on the rotating shaft 36, so that the flocculant in the feeding cylinder 10 is stirred and crushed in advance before being crushed.

[0052] Further, to facilitate the rapid blanking of the dry powder, a vibrator 46 is fixed on the outer side wall of the feeding cylinder 10 to vibrate the feeding cylinder 10. The vibrator 46 is connected to the control box 2.

[0053] The above-mentioned electronic components are all connected to the control box and the power supply.

[0054] The utility model has the following technical effects.

[0055] By installing two distribution pipes and the internal spiral conveyor rod, the utility model can achieve both adding flocculant into the tank body and directly adding it into the sewage according to needs. Through the slidable conveyor rod motor, it can be realized to use one motor to switch according to the actual situation.

[0056] The utility model uses a vacuum pump, a feeding cylinder, and a feeding cylinder for feeding, eliminating manual feeding, improving the feeding efficiency, and reducing the labor force.

[0057] The utility model can pre-crush the caked flocculant through the crushing roller, improving the dissolution rate of the flocculant in water.

[0058] The utility model realizes the sealing and blanking of the feeding cylinder through the sealing disk and the rotating disk, with low cost, and can also be used in cooperation with the vacuum pump. The sealed feeding makes the feeding speed faster.

[0059] The utility model can realize the pre-stirring of the flocculant by installing a rotating shaft and a stirring roller in the feeding cylinder, prevent the flocculant from caking, and realize the sealing and blanking of the sealing disc and the rotating disc according to the rotation of the rotating shaft itself, in cooperation with structures such as a push rod, a push column, a sliding shaft, and an arc-shaped groove, saving energy. There is no need to additionally install a sealing and opening device.

[0060] Although the content of the present utility model has been introduced in detail through the above preferred embodiments, it should be recognized that the above description should not be regarded as a limitation of the present utility model. After those skilled in the art have read the above content, various modifications and substitutions of the present utility model will be obvious. Therefore, the protection scope of the present utility model should be defined by the appended claims.
