Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a scale inhibitor granule feeding device. Background Technology

[0002] In the process of wastewater treatment, especially industrial wastewater treatment, the water may contain a large amount of hardness components such as calcium and magnesium ions. These components may form scale in the treatment equipment (such as pipes, heat exchangers, membrane systems, etc.), affecting the normal operation and treatment efficiency of the equipment. Using scale inhibitors can prevent these hardness components from depositing on the surface of the equipment, thereby maintaining the high efficiency of the equipment.

[0003] Before use, scale inhibitors need to be mixed with water in a certain proportion. For example, Chinese Patent Publication No. CN222324981 U discloses a scale inhibitor particle feeding device, including a base and a mixing tank. The mixing tank is installed on the upper part of the base, and a premixing component is arranged above the base. The premixing component can accelerate the dissolution and mixing of scale inhibitor particles. The premixing component includes a support frame, a heating base, and a premixing tank. The support frame is installed on the upper part of the base, the heating base is installed on top of the support frame, and the premixing tank is installed on the upper part of the heating base. This relates to the field of scale inhibitor technology: by setting a feeding device on the scale inhibitor mixing tank, the liquid in the mixing tank is first extracted and heated, then the scale inhibitor particles and solution are premixed and dissolved, and finally the mixture is introduced into the mixing tank for mixing, thereby accelerating the dissolution and mixing of scale inhibitor particles and improving the mixing efficiency of scale inhibitor particles.

[0004] In practice, the scale inhibitor is directly injected into the premixing tank through the feeding hopper. However, with a fixed amount of water in the premixing tank, it is not convenient to distribute the scale inhibitor. Distributing too much or too little scale inhibitor will affect the mixing efficiency between the scale inhibitor and water, resulting in poor practicality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the addition of scale inhibitors is inconvenient to distribute, and to propose a scale inhibitor granule feeding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a scale inhibitor particle feeding device, including a mixing tank, the mixing tank having a stirring mechanism inside, and a fixed frame fixedly connected to the top, the fixed frame having a dispensing component for adding scale inhibitor particles;

[0008] The dispensing component includes a feeding cylinder and a baffle. The baffle is disposed inside the feeding cylinder by an elastic structure, and the elastic structure is used to adjust the height of the baffle.

[0009] Furthermore, the dispensing assembly also includes a bracket, which is fixedly connected to the top of the fixed frame. The bracket has a U-shaped structure, and a cylindrical component is slidably connected to it on the open side. The top side of the cylindrical component extends outward to form a stop portion.

[0010] Furthermore, a storage cylinder is fixedly connected to the top of the support. The initial position of the cylinder is connected to the outlet of the storage cylinder. The cylinder moves back and forth through a drive component, and the cylinder also closes the outlet of the storage cylinder through the stop portion.

[0011] Furthermore, the bottom of the feeding cylinder is sloping and has a discharge port. The feeding cylinder is sleeved inside the cylinder. A connecting part is provided on the periphery of the feeding cylinder. The connecting part is slidably connected in the guide groove on the outer wall of the cylinder. A compression spring is also fixedly connected between the connecting part and the cylinder.

[0012] Furthermore, a guide portion is fixedly connected to one side of the bottom of the bracket. The guide portion is bent, with the bent portion at the bottom inclined and sliding against the connecting portion.

[0013] Furthermore, the elastic structure includes a connecting rod, the top of which passes through the bottom of the feeding cylinder and is fixedly connected to the baffle. The bottom of the connecting rod has a plurality of protruding structures evenly distributed thereon, and the bottom and the protruding structures together form a deformation groove along the centerline.

[0014] Furthermore, the protruding structure abuts against and slides against the feeding cylinder through the deformation groove, wherein the top of the fixing frame abuts against the feeding cylinder, and an avoidance groove is also provided at the top of the fixing frame, the avoidance groove being used to avoid the connecting rod.

[0015] The beneficial effects of the scale inhibitor granule feeding device proposed in this utility model are as follows: This utility model has a distribution component at the top of the mixing tank. The cylinder is driven by the drive component to move the feeding cylinder back and forth. During the back and forth movement of the feeding cylinder, in conjunction with the baffle, the appropriate scale inhibitor can be distributed and fed within a relatively accurate range, preventing the addition of too much or too little scale inhibitor into the mixing tank and ensuring that it can be fully dissolved due to mismatched water volume. In addition, the height of the baffle inside the feeding cylinder can be adjusted through the elastic structure, thereby distributing and feeding the scale inhibitor by changing the internal space of the feeding cylinder, so as to ensure that the scale inhibitor can be fully mixed with the appropriate amount of feeding under different water ratios.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A scale inhibitor particle feeding device includes a mixing tank 1, a stirring mechanism 2 is provided inside the mixing tank 1, and a fixing frame 3 is fixedly connected to the top, and a dispensing component 4 for adding scale inhibitor particles is provided on the fixing frame 3.

[0024] The dispensing component 4 includes a feeding cylinder 41 and a baffle 42. The baffle 42 is disposed inside the feeding cylinder 41 by an elastic structure 5, and the elastic structure 5 is used to adjust the height of the baffle 42.

[0025] In some embodiments, before use, the scale inhibitor particles need to be mixed with water in a certain proportion. The scale inhibitor is fed intermittently by the distribution component 4 to ensure that the stirring mechanism 2 is stirred evenly. On the other hand, by distributing the feed and adjusting the height of the baffle 42, it can be better mixed with different proportions of water.

[0026] Furthermore, the distribution component 4 also includes a bracket 43, which is fixedly connected to the top of the fixed frame 3. The bracket 43 has a U-shaped structure and a cylindrical member 44 is slidably connected to it on the open side. The top side of the cylindrical member 44 extends outward to form a stop portion 441.

[0027] Furthermore, a storage cylinder 45 is fixedly connected to the top of the bracket 43. The initial position of the cylinder 44 is connected to the outlet of the storage cylinder 45. The cylinder 44 moves back and forth through the drive member 46, and the cylinder 44 also closes the outlet of the storage cylinder 45 through the stop part 441.

[0028] In this embodiment, a corresponding feed inlet is provided between the mixing tank 1 and the fixed frame 3. The bracket 43 is fixedly connected to the feed inlet by the support feet on both sides. The driving component 46 is a cylinder, which is fixedly connected to the fixed frame 3. The shaft end of the cylinder is fixedly connected to the cylinder 44. The driving component 46 is used to drive the cylinder 44 to drive the feeding cylinder 41 to move back and forth.

[0029] Specifically, the discharge port of the storage cylinder 45 extends into the bracket 43. In the initial state, the top opening of the feeding cylinder 41 corresponds to the discharge port of the storage cylinder 45. The scale inhibitor enters the feeding cylinder 41. Then, the driving component 46 drives the cylinder 44 to move. After the cylinder 44 disengages from the storage cylinder 45, the discharge port of the storage cylinder 45 is closed by the stop part 441.

[0030] More specifically, the bottom of the feeding cylinder 41 is inclined and has a discharge port. The feeding cylinder 41 is sleeved inside the cylinder 44. A connecting part 411 is provided on the periphery of the feeding cylinder 41. The connecting part 411 is slidably connected in the guide groove 442 on the outer wall of the cylinder 44. A compression spring 47 is also fixedly connected between the connecting part 411 and the cylinder 44.

[0031] In general, a guide portion 48 is also fixedly connected to one side of the bottom of the bracket 43. The guide portion 48 is bent, and the bent part at the bottom is inclined and slides against the connecting portion 411.

[0032] It is worth mentioning that the height of the cylinder 44 is matched with that of the feeding cylinder 41. Because the feeding cylinder 41 is fitted inside the cylinder 44, the side wall outlet of the feeding cylinder 41 is closed by the cylinder 44 to prevent the scale inhibitor from leaking.

[0033] Among them, the cylinder 44 drives the feeding cylinder 41 to move. When the feeding cylinder 41 is disengaged from the fixed frame 3, it moves downward under the action of the compression spring 47, and the scale inhibitor is discharged from the outlet. It should be noted that the two ends of the compression spring 47 are fixedly connected to the connecting part 411 and the cylinder 44 to prevent the feeding cylinder 41 from disengaging from the cylinder 44.

[0034] During the reset process of the feeding cylinder 41, the connecting part 411 slides against the guide part 48, and the feeding cylinder 41 is moved upward by the guide part 48 to reset, so as to carry out the next feeding.

[0035] Furthermore, the elastic structure 5 includes a connecting rod 51, the top of which passes through the bottom of the feeding cylinder 41 and is fixedly connected to the baffle 42. The bottom of the connecting rod 51 is evenly distributed with several protruding structures 52, and the bottom of the connecting rod 51 and the protruding structures 52 together form a deformation groove 53 along the center line.

[0036] Finally, the protruding structure 52 abuts against and slides against the feeding cylinder 41 through the deformation groove 53. The top of the fixing frame 3 abuts against the feeding cylinder 41, and an avoidance groove 31 is also provided on the top of the fixing frame 3. The avoidance groove 31 is used to avoid the connecting rod 51.

[0037] In this embodiment, both the connecting rod 51 and the baffle 42 are preferably made of materials with deformation capabilities such as rubber and plastic. The top of the connecting rod 51 can be threadedly connected to the baffle 42. The height of the baffle 42 can be adjusted by adjusting the height of the connecting rod 51, so as to adjust the internal space of the feeding cylinder 41 within a relatively accurate range.

[0038] In specific operation, the protruding structure 52 contacts and slides against the bottom of the feeding cylinder 41 through the deformation groove 53. After the protruding structure 52 is placed inside the feeding cylinder 41, it recovers its deformation and then contacts the bottom of the feeding cylinder 41 to achieve the adjustment function.

[0039] Among them, such as Figure 5 As shown, the baffle 42 extends outward from one side of the discharge port of the feeding cylinder 41 to form an extension. The extension abuts against the inner wall of the cylinder 44 to prevent the scale inhibitor from leaking. Specifically, the baffle 42 is provided with a second deformation groove on the side away from the extension. The baffle 42 is deformed and placed inside the feeding cylinder 41 through the second deformation groove, and it also fits against the inner wall of the feeding cylinder 41.

[0040] Working method: During operation, the protruding structure 52 slides against the bottom of the feeding cylinder 41 through the deformation groove 53. After the protruding structure 52 is placed inside the feeding cylinder 41, it recovers its deformation and then the protruding structure 52 abuts against the bottom of the feeding cylinder 41, thereby achieving the function of adjusting the height of the baffle 42.

[0041] When the top opening of the cylinder 44 corresponds to the discharge port of the storage cylinder 45, the scale inhibitor enters the interior of the feeding cylinder 41. The driving component 46 drives the cylinder 44 and the feeding cylinder 41 to move. When the bottom of the feeding cylinder 41 is disengaged from the fixing frame 3, the feeding cylinder 41 moves downward under the action of the compression spring 47, and the scale inhibitor is discharged along the discharge port.

[0042] When the cylinder 44 moves backward to reset, the connecting part 411 slides against the guide part 48, which in turn drives the feeding cylinder 41 to move upward to reset, ready for the next feeding.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
