Description

Technical Field

[0001] The utility model relates to the technical field of industrial chillers, in particular to an industrial chiller with a scale removal structure. Background Technique

[0002] At present, during the long-term operation of industrial chillers, the internal circulating water pipes are prone to scale formation. In the existing scale removal methods, there are many problems when using liquid medicine for scale removal.

[0003] On the one hand, it is difficult to achieve quantitative addition. Most rely on manual experience or simple tools for addition, resulting in a large difference in the amount of liquid medicine added each time. On the other hand, it is impossible to ensure the addition of liquid medicine at a certain frequency. The instability of the addition time and dosage greatly reduces the scale removal effect. Adding liquid medicine without quantitative and frequency control will lead to poor scale removal effect, increase the risk of equipment damage, and may also deteriorate the water quality in the chiller, affecting the stable operation of the entire industrial production system. Content of the Utility Model

A quantitative component for quantifying the added scale removal liquid medicine is arranged on one side of the adding component. The adding component includes an adding cylinder arranged on the top of the inner cavity of the chassis. The bottom end of the adding cylinder is fixedly connected and communicated with a first adding pipe. The bottom end of the first adding pipe is fixedly connected and communicated with an extrusion cylinder. One end of the extrusion cylinder is fixedly connected and communicated with a second adding pipe. One end of the second adding pipe is fixedly connected and communicated with a third adding pipe. The bottom end of the third adding pipe is fixedly connected with the adjacent circulating water pipe.

[0006] Through the above technical solutions, the adding component and the quantitative component cooperate with each other to realize the addition of scale removal liquid medicine into the circulating water pipe, which helps to remove the scale in the circulating water pipe and ensure the normal operation of the chiller.

[0007] As a further improvement of the above solution, a support plate arranged in a "C" shape is fixedly installed on the top of the inner cavity of the chassis.

A first spring is sleeved on the first limiting rod, and the two ends of the first spring abut against the first block and the first limiting plate, respectively.

[0012] With the above technical solution, when the pressure inside the extrusion cylinder decreases, the first spring pushes the first block to block the first flow port, preventing the liquid medicine inside the extrusion cylinder from flowing back into the addition cylinder; when suction is generated inside the extrusion cylinder, the first block can be sucked open, allowing the liquid medicine inside the addition cylinder to enter the extrusion cylinder.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Please combine Figures 1-4, An industrial chiller with a scale removal structure in this embodiment includes a chassis 1. Inside the chassis 1, there are multiple circulating water pipes 2 for water circulation. On the top of the chassis 1, there is an adding component for adding scale removal liquid medicine, and on one side of the adding component, there is a quantitative component for quantifying the added scale removal liquid medicine.

[0027] The adding component includes an adding cylinder 301 arranged at the top of the inner cavity of the chassis 1. The bottom end of the adding cylinder 301 is fixedly connected and communicated with a first adding pipe 302. The bottom end of the first adding pipe 302 is fixedly connected and communicated with an extrusion cylinder 303. One end of the extrusion cylinder 303 is fixedly connected and communicated with a second adding pipe 304. One end of the second adding pipe 304 is fixedly connected and communicated with a third adding pipe 305. The bottom end of the third adding pipe 305 is fixedly connected with the adjacent circulating water pipe 2.

[0028] The adding component and the quantitative component cooperate with each other to realize adding scale removal liquid medicine into the circulating water pipe 2, which helps to remove the scale in the circulating water pipe 2 and ensure the normal operation of the chiller.

[0029] On the top of the inner cavity of the chassis 1, there is a support plate 5 arranged in a "C" shape. The top of the adding cylinder 301 penetrates through the support plate 5 and the chassis 1 upwards in sequence. There is an adding port on the top of the adding cylinder 301, and a cover plate 6 is installed on the adding port.

[0030] The support plate 5 plays a supporting role for the adding cylinder 301 to ensure the stability of the adding cylinder 301. The cover plate 6 can prevent dust and other impurities from entering the adding cylinder 301 and ensure the cleanliness of the scale removal liquid medicine.

[0031] The quantitative component includes a first push plate 401 slidably arranged inside the extrusion cylinder 303. On one side of the first push plate 401, there is a push rod 402 fixedly installed. One end of the push rod 402 extends to the outside of the extrusion cylinder 303 and is fixedly installed with a second push plate 403. On one side of the second push plate 403, there is a push cylinder 404. The pushing end of the push cylinder 404 is fixedly installed with one side of the second push plate 403. The bottom side of the push cylinder 404 is fixedly installed with the inner wall of the support plate 5. A fixed block 7 is fixedly sleeved on the cylindrical surface of the extrusion cylinder 303, and the fixed block 7 is fixedly installed with the inner wall of the support plate 5.

[0032] When the push cylinder 404 works, the pushing end pushes the second push plate 403,带动 the first push plate 401 to move inside the extrusion cylinder 303, realizing the extrusion of the liquid medicine in the extrusion cylinder 303, so as to achieve the purpose of quantitatively adding the liquid medicine.

[0033] A first sealing plate 8 is fixedly installed inside the first adding tube 302. A first flow port is opened on one side of the first sealing plate 8, and a first block 9 is provided inside the first flow port. A first limiting rod 10 is fixedly installed on one side of the first block 9. A first limiting plate 11 is slidably sleeved on the first limiting rod 10. The first limiting plate 11 is fixedly installed to the inner wall of the first adding tube 302. A first spring 12 is sleeved on the first limiting rod 10. The two ends of the first spring 12 abut against the first block 9 and the first limiting plate 11, respectively.

[0034] When the pressure inside the extrusion cylinder 303 decreases, the first spring 12 pushes the first block 9 to block the first flow port, preventing the liquid medicine inside the extrusion cylinder 303 from flowing back into the addition cylinder 301; when suction is generated inside the extrusion cylinder 303, the first block 9 can be sucked open, allowing the liquid medicine inside the addition cylinder 301 to enter the extrusion cylinder 303.

[0035] A second sealing plate 13 is fixedly installed inside the second adding tube 304. A second flow port is opened on one side of the second sealing plate 13, which passes through itself. A second block 14 is provided inside the second flow port. A second limiting rod 15 is fixedly installed on one side of the second block 14. A second limiting plate 16 is slidably sleeved on the second limiting rod 15. The second limiting plate 16 is fixedly installed to the inner wall of the second adding tube 304. A second spring 17 is sleeved on the second limiting rod 15. The two ends of the second spring 17 abut against the second block 14 and the second limiting plate 16, respectively.

[0036] Under the pressure inside the extrusion cylinder 303, the second block 14 can be pushed open, allowing the liquid medicine to enter the second addition tube 304; when the pressure disappears, the second spring 17 pushes the second block 14 to block the second flow port, preventing the liquid medicine from flowing back.

[0037] A connecting rod 18 is rotatably mounted on the top of the inner cavity of the third adding tube 305, and multiple stirring blades 19 arranged in a ring array are fixedly mounted on the cylindrical surface at the bottom end of the connecting rod 18.

[0038] The stirring blade 19 can disperse the chemical solution entering the third addition pipe 305, allowing it to enter the circulating water pipe 2 more evenly and improving the descaling effect.

[0039] The implementation principle of an industrial chiller with a descaling structure in this application embodiment is as follows: the cover plate 6 is opened and the chemical solution is added into the inside of the adding cylinder 301. When descaling solution needs to be added, the cylinder 404 is pushed to start working. The pushing end of the cylinder 404 extends forward and pushes the second pushing plate 403 to move. Since the second pushing plate 403 is fixedly connected to the pushing rod 402, the pushing rod 402 will move together with the second pushing plate 403. The other end of the pushing rod 402 is fixed to the first pushing plate 401, so the first pushing plate 401 will also move forward in the extrusion cylinder 303.

[0040] The forward movement of the first push plate 401 reduces the space inside the extrusion cylinder 303, thereby generating pressure. Under this pressure, the second block 14, which originally blocked the second flow port, is pushed. The second block 14, along with the second limiting rod 15, slides on the second limiting plate 16, overcoming the elastic force of the second spring 17, and is pushed away from the second flow port, allowing the liquid medicine in the extrusion cylinder 303 to enter the second addition tube 304 through the second flow port, and then be injected into the third addition tube 305.

[0041] The chemical solution entering the third addition pipe 305 will encounter the connecting rod 18, which is rotated and installed at the top of its inner cavity. Multiple stirring blades 19, which are fixedly installed on the cylindrical surface at the bottom of the connecting rod 18, will be driven to rotate by the flowing chemical solution, thereby changing the flow direction of the chemical solution and allowing the chemical solution to enter the interior of the circulating water pipe 2 from multiple directions. This disperses the concentrated injection of chemical solution, making it enter the circulating water pipe 2 more evenly and mix it fully with the circulating water, thereby improving the descaling effect.

[0042] When the pushing end of the cylinder 404 retracts, the space inside the extrusion cylinder 303 increases, the pressure decreases, and a suction force is generated. Under the action of the suction force, the first block 9 is pulled towards the extrusion cylinder 303. The first block 9 slides on the first limit rod 10, overcomes the elastic force of the first spring 12, and leaves the first flow port. At this time, the liquid medicine inside the addition cylinder 301 enters the interior of the extrusion cylinder 303 through the first flow port under the combined action of gravity and suction force.

[0043] In this way, by pushing the cylinder 404 to reciprocate, the descaling solution is added in a quantitative manner. Each time the cylinder 404 is pushed, the amount of solution squeezed out is determined by the distance the first push plate 401 moves and the internal volume of the extrusion cylinder 303. Since the cylinder 404 works according to the set time interval, the solution can be added to the circulating water pipe 2 at a certain frequency.

[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
