Description

Technical Field

[0001] This utility model relates to a high-efficiency absorption graphite tower, and more particularly to a high-efficiency absorption graphite tower applied in the field of graphite towers. Background Technology

[0002] When using a high-efficiency and environmentally friendly graphite absorption tower, it is important to clean it regularly. If there is dirt inside the equipment, it should not be used anymore. It should be cleaned thoroughly before use, otherwise it will easily affect the operating efficiency of the tower.

[0003] To address the issue of declining absorption efficiency in graphite absorption towers, a certain high-efficiency and environmentally friendly graphite absorption tower on the market adopts an electric cleaning structure design, which has a certain market share.

[0004] Chinese utility model patent CN219559203U discloses a high-efficiency and environmentally friendly graphite absorption tower, including a tower body. Multiple sieve plates are fixedly connected to the inner end of the tower body, arranged from top to bottom. An electric guide rail is fixedly connected to the lower inner wall of the tower body. A vertical rod is slidably connected to the upper end of the electric guide rail. Working rods are symmetrically rotatably connected to the left and right ends of the vertical rod, with each corresponding working rod engaging with a corresponding sieve plate. Multiple scraping vertical strips are fixedly connected to the lower end of the working rods. During operation, two electric shafts rotate the two working rods back above the sieve plates. The scraping vertical strips at the lower end of the working rods scrape away the deposits on the sieve plate surface through continuous radial friction. The deposits are then sucked out of the tower body by an external suction pump through the suction port. This design ensures the unobstructed flow of the sieve plates, thereby guaranteeing the tower's efficiency.

[0005] Existing graphite towers (graphite absorption towers) require multiple power components to achieve the goal of clearing the screen plates to ensure the tower's efficiency (equivalent to improving the continuous absorption efficiency of the graphite tower). These power components not only increase the overall equipment cost of the graphite tower, but the power components located inside the graphite tower (such as electric guide rails and electric shafts) are also susceptible to material corrosion and damage, leading to increased maintenance frequency and costs. Although the absorption efficiency of the graphite tower is improved, it is not conducive to achieving the goals of energy saving and cost reduction. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is how to design a high-efficiency absorption graphite tower that can automatically convey sieve plates and at the same time achieve energy saving, cost reduction and efficiency improvement.

[0007] To solve the above problems, this utility model provides a high-efficiency absorption graphite tower, including a tower body and a base for fixing the tower body, and multiple sieve plates are fixed in sequence from top to bottom inside the tower body;

[0008] A rotating rod is rotatably installed inside the tower. A cleaning mechanism is rotatably connected to the circumference of the rotating rod via a connecting seat. The cleaning mechanism is used to clean the deposits on the screen plate. The cleaning mechanism is also elastically connected to the connecting seat via an elastic structure. Under normal conditions, the cleaning mechanism fits against the circumference of the rotating rod. When the cleaning mechanism is subjected to centrifugal force, it overcomes the elastic force of the elastic structure, unfolds, and fits against the upper surface of the screen plate.

[0009] A suction pump is fixed inside the base. The suction pump has two inlets and one outlet on one side. A discharge pipe is fixed and connected to the outlet of the suction pump and passes through the base.

[0010] The rotating rod is a hollow rod with an internal suction channel. The two inlets of the suction pump are connected to the outside and the lower end of the suction channel, respectively. A follower is also fixedly sleeved at the lower end of the rotating rod. The follower rotates as the outside air enters the suction pump.

[0011] In the aforementioned high-efficiency graphite tower, compared to existing technologies, an elastic structure is used instead of an electric rotating shaft, and a follower component is used instead of a motor and electric slide rail, thereby reducing the overall cost of the equipment. At the same time, it can still achieve the purpose of cleaning the deposits on the sieve plate, improving the absorption efficiency of the graphite tower while reducing the subsequent maintenance frequency and maintenance costs, thus achieving the goals of cost reduction, efficiency improvement, and energy saving.

[0012] As a further improvement of this application, one of the inlets of the suction pump is fixedly connected to an air intake shroud, and an air inlet is provided on one side of the base. The air inlet is connected to the air intake shroud. The follower includes a driven turbine, which is rotatably installed inside the air intake shroud. The driven turbine is fixedly sleeved on the lower end of the rotating rod. The lower end of the suction channel is connected to the other inlet of the suction pump. The lower end of the rotating rod rotates through the air intake shroud and is rotatably connected to the other inlet of the suction pump.

[0013] As a further improvement of this application, the cleaning mechanism includes a cleaning rod, a cleaning brush, and a dust suction hood. One end of the cleaning rod is rotatably connected to the connecting seat, the cleaning brush is fixed to one side of the lower end of the cleaning rod, and the dust suction hood is fixed to the other side of the lower end of the cleaning rod. When the cleaning brush and the dust suction hood are in contact with the upper surface of the screen plate, they cover the upper surface of the screen plate during rotation.

[0014] The dust hood is connected to the suction channel via a connecting hose.

[0015] As a further improvement of this application, the connecting seat is fixed to the outside of the rotating rod, and a connecting shaft is rotatably connected to the connecting seat, with the connecting shaft fixedly passing through the end of the cleaning rod.

[0016] As another improvement of this application, a mounting cavity is provided inside the connecting seat, the connecting shaft rotates through the side wall of the connecting seat, and part of the connecting shaft is located inside the mounting cavity;

[0017] The elastic structure includes a torsion spring, which is installed in the mounting cavity and movably sleeved on the connecting shaft. The two ends of the torsion spring are fixed to the inner sidewall of the mounting cavity and the periphery of the connecting shaft, respectively.

[0018] As another improvement of this application, the outer wall of the rotating rod is integrally formed with a retaining edge and an inclined convex wall. The retaining edge is located at the top of the inclined convex wall, and the inclined convex wall is a wedge-shaped protrusion with the upper end protruding a greater distance than the lower end. The retaining edge and the inclined convex wall correspond to the position of the cleaning rod.

[0019] In summary, during use, simply start the suction pump. The suction pump will draw in external air through one of the inlets. When air is drawn in, the follower rotates, which in turn drives the rotating rod to rotate. When the rotating rod rotates, the cleaning mechanism is subjected to centrifugal force, which overcomes the elasticity of the elastic structure and unfolds, adhering to the upper surface of the sieve plate. This cleans the upper surface of the sieve plate. The cleaned deposits enter the suction pump through the suction channel and the other inlet of the suction pump. After mixing with the drawn-in air, they are discharged through the discharge pipe. Only one power unit is needed to complete the entire automatic cleaning operation, thereby improving the absorption efficiency of the graphite tower.

[0020] Compared to existing technologies, the use of an elastic structure to replace the electric rotating shaft and a follower component to replace the motor and electric slide rail reduces the overall cost of the equipment. At the same time, it can still achieve the purpose of cleaning the deposits on the screen plate, improving the absorption efficiency of the graphite tower, and reducing the frequency and cost of subsequent maintenance, thus achieving the goals of cost reduction, efficiency improvement, and energy saving.

[0027] The following describes one embodiment of this application in detail with reference to the accompanying drawings.

[0028] Implementation method 1:

[0029] Figure 1-4 A graphite tower for high-efficiency absorption is shown, including a tower body 1 and a base 2 for fixing the tower body 1. Multiple sieve plates 3 are fixed in sequence from top to bottom inside the tower body 1.

[0030] A rotating rod 4 is rotatably installed inside the tower body 1. A cleaning mechanism 5 is rotatably connected to the circumference of the rotating rod 4 via a connecting seat 6. The cleaning mechanism 5 is used to clean the attachments on the screen plate 3. The cleaning mechanism 5 is also elastically connected to the connecting seat 6 via an elastic structure. Under normal conditions, the cleaning mechanism 5 fits against the circumference of the rotating rod 4. When the cleaning mechanism 5 is subjected to centrifugal force, it overcomes the elastic force of the elastic structure, unfolds, and fits against the upper end face of the screen plate 3.

[0031] A suction pump 7 is fixed inside the base 2. The suction pump 7 has two inlets and one outlet on one side. A discharge pipe 8 is fixed and connected to the outlet of the suction pump 7. The discharge pipe 8 passes through the base 2.

[0032] The rotating rod 4 is a hollow rod with a suction channel 401 inside. The two inlets of the suction pump 7 are connected to the outside and the lower end of the suction channel 401, respectively. A follower is also fixedly sleeved at the lower end of the rotating rod 4. The follower rotates as the outside air enters the suction pump 7.

[0033] Based on the above structure, during use, simply start the suction pump 7. The suction pump 7 can draw in external air through one of the inlets. When the air is drawn in, the follower rotates, which in turn drives the rotating rod 4 to rotate. When the rotating rod 4 rotates, the cleaning mechanism 5 is subjected to centrifugal force to overcome the elasticity of the elastic structure and unfold, and fits against the upper end face of the sieve plate 3, thereby cleaning the upper surface of the sieve plate 3. The cleaned deposits enter the suction pump 7 through the suction channel 401 and the other inlet of the suction pump 7, and then mix with the drawn-in air and are discharged through the discharge pipe 8. Only one power component (suction pump 7) is needed to complete the entire automatic cleaning operation, thereby improving the absorption efficiency of the graphite tower.

[0034] Compared with existing technologies, the use of an elastic structure to replace the electric rotating shaft and a follower component to replace the motor and electric slide rail reduces the overall cost of the equipment. At the same time, it can still achieve the purpose of cleaning the deposits on the screen plate 3, improving the absorption efficiency of the graphite tower while reducing the frequency and cost of subsequent maintenance, thus achieving the goals of cost reduction, efficiency improvement and energy saving.

[0035] Furthermore, one of the inlets of the suction pump 7 is fixedly connected to the air intake shroud 701, and an air intake 201 is provided on one side of the base 2. The air intake 201 is connected to the air intake shroud 701. The follower includes a driven turbine 9, which is rotatably installed inside the air intake shroud 701. The driven turbine 9 is fixedly sleeved on the lower end of the rotating rod 4. The lower end of the suction channel 401 is connected to the other inlet of the suction pump 7. The lower end of the rotating rod 4 rotates through the air intake shroud 701 and is rotatably connected to the other inlet of the suction pump 7.

[0036] After the suction pump 7 is started, air enters the air intake shroud 701 from the outside through the air intake port 201, and then enters one of the inlets of the suction pump 7 through the air intake shroud 701. During the air flow, the driven turbine 9 is driven to rotate, thereby driving the rotating rod 4 to rotate.

[0037] Furthermore, the cleaning mechanism 5 includes a cleaning rod 501, a cleaning brush 502, and a dust suction cover 503. One end of the cleaning rod 501 is rotatably connected to the connecting seat 6. The cleaning brush 502 is fixed to one side of the lower end of the cleaning rod 501, and the dust suction cover 503 is fixed to the other side of the lower end of the cleaning rod 501. When the cleaning brush 502 and the dust suction cover 503 are in contact with the upper surface of the sieve plate 3, they cover the upper surface of the sieve plate 3 during rotation.

[0038] The dust hood 503 is connected to the suction channel 401 via a connecting hose 504.

[0039] Furthermore, the connecting seat 6 is fixed to the outside of the rotating rod 4, and a connecting shaft 601 is rotatably connected to the connecting seat 6. The connecting shaft 601 is fixedly inserted through the end of the cleaning rod 501.

[0040] The connecting seat 6 has an installation cavity 602, the connecting shaft 601 rotates through the side wall of the connecting seat 6, and part of the connecting shaft 601 is located in the installation cavity 602;

[0041] The elastic structure includes a torsion spring 603, which is installed in the mounting cavity 602 and movably sleeved on the connecting shaft 601. Both ends of the torsion spring 603 are fixed to the inner wall of the mounting cavity 602 and the periphery of the connecting shaft 601, respectively.

[0042] By using the connecting shaft 601 and the torsion spring 603, not only can the cleaning rod 501 be rotatably connected to the connecting seat 6, but the cleaning rod 501 can also overcome the elastic force of the torsion spring 603 and unfold when subjected to centrifugal force, and fit against the upper surface of the cleaning screen plate 3. When the rotating rod 4 stops rotating, the cleaning rod 501 automatically retracts under the elastic force of the torsion spring 603, thus fitting against the outside of the rotating rod 4 and avoiding affecting the normal operation of the screen plate 3.

[0043] Furthermore, the outer wall of the rotating rod 4 is integrally formed with a retaining edge 402 and an inclined convex wall 403. The retaining edge 402 is located at the top of the inclined convex wall 403. The inclined convex wall 403 is a wedge-shaped protrusion with the upper end protruding a greater distance than the lower end. The retaining edge 402 and the inclined convex wall 403 correspond to the position of the cleaning rod 501.

[0044] When the cleaning rod 501 automatically retracts under the elastic force of the torsion spring 603, the side wall of the cleaning rod 501 fits against the inclined convex wall 403, thus making the cleaning rod 501 form a slightly inclined vertical state. On the one hand, this can minimize the impact on the normal operation of the screen plate 3, and on the other hand, it allows the cleaning rod 501 to unfold better when affected by centrifugal force. When the cleaning rod 501, cleaning brush 502, and dust hood 503 are retracted, the upper ends are blocked by the retaining edge 402, which can reduce the direct impact of the material in the graphite tower on the cleaning rod 501, cleaning brush 502, and dust hood 503, reduce the damage to the cleaning rod 501, cleaning brush 502, and dust hood 503, and extend their service life.

[0045] It should be further noted that the technical features of the tower body, base, sieve plate, suction pump, etc. involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0046] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
