Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically a horizontal centrifuge. Background Technology

[0002] A horizontal centrifuge is a highly efficient device that utilizes centrifugal force to achieve liquid-solid separation, widely used in chemical, pharmaceutical, food, and environmental protection industries. Its drum is placed horizontally, and the high-speed rotation generates a powerful centrifugal force, causing solid particles in the suspension to settle on the inner wall of the drum, forming a solid ring layer. The liquid, however, is discharged through a filter medium or small holes in the drum, thus achieving liquid-solid separation. This equipment boasts advantages such as continuous operation, large processing capacity, low power consumption per unit output, and strong adaptability, meeting the solid-liquid separation needs of various industries. Furthermore, the advanced horizontal design of the centrifuge ensures the machine remains balanced during high-speed operation, reducing vibration and noise and improving the comfort of the operating environment.

[0003] Patent CN209333975U discloses a horizontal centrifuge, comprising a casing, a rotating drum housed within the casing, and a spiral pusher housed within the rotating drum. The rotating drum and the spiral pusher are coaxially aligned. One end of the rotating drum is tapered, with a solid phase discharge port at the tapered end and a clear liquid discharge port at the other end. A first filter and a second filter are located within the clear liquid discharge port, with the second filter positioned directly below the first filter. Both the first and second filter devices include trapezoidal filter frames, with a connecting plate extending outwards from the lower outer circumference of each filter frame. The mesh size of the filter frames in the second filter device is smaller than that in the first filter device. Both the first and second filter devices are fixed within the clear liquid discharge port by a support device. This device effectively reduces residue and improves the purity of the liquid phase.

[0004] Although the above-mentioned device can reduce residue and improve the purity of liquid phase, it still has the following shortcomings:

[0005] During operation, horizontal centrifuges generate significant heat due to friction between the drum and the material, as well as wear and tear on mechanical parts, when running at high speed. Insufficient heat dissipation can cause the drum material to deform due to high temperatures, affecting separation accuracy and potentially damaging the material being centrifuged. The aforementioned system lacks proper heat dissipation for the drum, thus hindering centrifugation. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a horizontal centrifuge that can provide heat dissipation for the centrifuge drum, preventing the drum from deforming due to high temperatures.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a horizontal centrifuge, including a centrifuge body, the centrifuge body including a drum, a heat dissipation component is attached to the outside of the drum, the heat dissipation component is connected to a cooling water circulation component through a water supply pipe, and four sets of cooling water circulation components and heat dissipation components are evenly arranged on the drum. A heat dissipation temperature sensor is embedded between each set of heat dissipation components on the top surface of the drum.

[0008] Furthermore, the heat dissipation assembly includes an annular heat-conducting plate attached to the outside of the drum, and a spiral water pipe attached inside the annular heat-conducting plate. The inlet and outlet of the spiral water pipe are located on the right side of the front end and the left side of the rear end of the annular heat-conducting plate, respectively. The spiral water pipe is connected to the cooling water circulation assembly through a water supply pipe.

[0009] Furthermore, the cooling water circulation assembly includes a cold water tank and a hot water tank. An inlet pump is installed on the top surface of the cold water tank, and a return pump is installed on the top surface of the hot water tank. Both the inlet pump and the return pump are connected to the inlet and outlet of the spiral water pipe respectively through water supply pipes. An inlet is installed on the top surface of the cold water tank, and an outlet is installed at the lower left side of the hot water tank.

[0010] Furthermore, both the cold water tank and the hot water tank are equipped with observation windows on the outside, and the observation windows are marked with water level.

[0011] Furthermore, a water tank temperature sensor is installed on the left side of the hot water tank.

[0012] Furthermore, a limiting plate is provided on the outside of the drum between each set of heat dissipation components, with the two sides of the limiting plate respectively attached to the outside of two annular heat-conducting plates.

[0013] Furthermore, buffer pads are provided on both sides of the limiting plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By installing a heat dissipation component on the outside of the drum, the drum can be cooled by water, which improves the heat dissipation efficiency; by installing a cooling water circulation component, the cooling water can be circulated, and hot water can also be guided to the place where it is needed through the outlet, which improves the resource utilization rate.

[0016] By setting up four sets of components and controlling them separately, the entire circumferential heat dissipation area of ​​the drum can be covered, avoiding local overheating. In conjunction with the heat dissipation temperature sensor, the flow rate of cooling water can be adjusted according to the real-time situation to achieve precise heat dissipation regulation.

[0017] By setting up an observation window and water level scale, staff can visually check the water level and replenish water in time to avoid heat dissipation failure due to water shortage; by setting up a water tank temperature sensor, it can work in conjunction with the heat dissipation temperature sensor to monitor the temperature of the drum and circulating water in real time, ensuring that the heat dissipation system works as needed and avoiding energy waste.

[0018] By setting a limit plate, the position of the heat dissipation components can be fixed to prevent the components from shifting when the centrifuge is running at high speed; by setting buffer pads on both sides of the limit plate, vibration can be absorbed, mechanical wear during equipment operation can be reduced, noise can be reduced, and the service life of the equipment can be extended.

[0024] 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.

[0025] like Figures 1 to 4 As shown, a horizontal centrifuge includes a centrifuge body 1, which includes a drum 101. A heat dissipation component 2 is attached to the outside of the drum 101. The heat dissipation component 2 is connected to a cooling water circulation component 4 through a water supply pipe 3. Four sets of cooling water circulation components 4 and heat dissipation components 2 are evenly arranged on the drum 101. A heat dissipation temperature sensor 102 is embedded between each set of heat dissipation components 2 on the top surface of the drum 101.

[0026] like Figure 1 As shown, the horizontal centrifuge in this utility model is similar in structure to the existing horizontal centrifuges. For example, the patent with announcement number CN209333975U discloses a horizontal centrifuge. The main improvement of this utility model is that it can perform heat dissipation treatment on the centrifuge drum to prevent the drum from deforming due to high temperature.

[0027] like Figures 1 to 4 As shown, in the present invention, a horizontal centrifuge is used in which the cold water tank 401 first introduces new cooling water through the addition port 405, and then the cooling water is sent to the inlet end of the spiral water pipe 202 through the water pump 403 on the top surface of the cold water tank 401 and the water delivery pipe 3. The cooling water will flow forward spirally in the spiral water pipe 202 and absorb the heat transferred from the annular heat conduction plate 201 to become hot water. Then it flows to the outlet end and flows out, completing the heat dissipation of the rotating drum 101.

[0028] The hot water flowing out will be drawn back into the hot water tank 402 by the return pump 404 through the water pipe 3, and then guided to the place where hot water is needed from the outlet 406 at the lower left end of the hot water tank 402, completing the circulation of cooling water. At the same time, during the heat dissipation process, the four sets of heat dissipation components 2 will monitor the temperature of the drum 101 and the circulating water in real time based on the temperature data transmitted by the heat dissipation temperature sensor 102, in conjunction with the water tank temperature sensor 409 set on the hot water tank 402, to ensure that the heat dissipation system works as needed. At the same time, the driving speed of each inlet pump 403 and return pump 404 will be adjusted in real time according to the demand and actual situation, thereby changing the flow rate of cooling water in the spiral water pipe 202 in different sections and achieving precise regulation of heat dissipation.

[0029] like Figure 1 and Figure 3 As shown, the heat dissipation assembly 2 includes an annular heat-conducting plate 201 attached to the outside of the rotating drum 101. A spiral water pipe 202 is attached inside the annular heat-conducting plate 201. The inlet and outlet of the spiral water pipe 202 are located on the right side of the front end and the left side of the rear end of the annular heat-conducting plate 201, respectively. The spiral water pipe 202 is connected to the cooling water circulation assembly 4 through the water supply pipe 3.

[0030] Specifically, when heat dissipation is required, cooling water is transported to the inlet end of the spiral water pipe 202 via the cooling water circulation component 4. The cooling water flows spirally forward within the spiral water pipe 202, absorbing heat transferred from the annular heat-conducting plate 201. The spiral shape prolongs the heat exchange time between the cooling water and the annular heat-conducting plate 201, increasing the contact area and improving heat dissipation efficiency. Subsequently, the cooling water flows to the outlet end and returns to the cooling water circulation component 4 via the water supply pipe 3, completing water-cooled heat dissipation. During the heat dissipation process, the four heat dissipation components 2 adjust the driving speed of each inlet pump 403 and return pump 404 in real time based on the temperature data transmitted by the heat dissipation temperature sensor 102, thereby changing the flow rate of cooling water in the spiral water pipe 202 at different sections and achieving precise regulation of heat dissipation.

[0031] like Figure 1 and Figure 4As shown, the cooling water circulation assembly 4 includes a cold water tank 401 and a hot water tank 402. The top surface of the cold water tank 401 is equipped with an inlet pump 403, and the top surface of the hot water tank 402 is equipped with a return pump 404. The inlet pump 403 and the return pump 404 are connected to the inlet and outlet of the spiral water pipe 202 respectively through the water supply pipe 3. The top surface of the cold water tank 401 is equipped with an inlet 405, and the lower left side of the hot water tank 402 is equipped with an outlet 406.

[0032] Specifically, during the heat dissipation process, the cold water tank 401 first introduces new cooling water through the inlet 405. Then, through the inlet pump 403 on the top surface of the cold water tank 401, and in conjunction with the water pipe 3, the cooling water is sent to the inlet end of the spiral water pipe 202. The water then flows and absorbs heat within the spiral water pipe 202. When the cooling water in the spiral water pipe 202 becomes hot water due to heat absorption and flows to the outlet end, this hot water is drawn back to the hot water tank 402 by the return pump 404 through the water pipe 3. Subsequently, it is guided from the outlet 406 at the lower left side of the hot water tank 402 to the location where hot water is needed, completing the cooling water circulation. During this circulation process, a continuous supply of cooling water is provided to the heat dissipation component 2, and hot water can also be transported to other locations where it is needed, improving resource utilization and increasing economic benefits.

[0033] like Figure 4 As shown, both the cold water tank 401 and the hot water tank 402 are provided with observation windows 407 on their outer sides, and water level scales 408 are provided on the observation windows 407.

[0034] Specifically, by setting observation windows 407 on both the cold water tank 401 and the hot water tank 402, and setting water level scales 408 on the observation windows 407, the staff can intuitively check the water level and replenish water in time, so as to avoid heat dissipation failure due to water shortage and improve the reliability of equipment operation.

[0035] like Figure 4 As shown, a water tank temperature sensor 409 is installed on the left side of the hot water tank 402.

[0036] Specifically, by installing a water tank temperature sensor 409 on the hot water tank 402, it can work in conjunction with the heat dissipation temperature sensor 102 to monitor the temperature of the drum 101 and the circulating water in real time, ensuring that the heat dissipation system works as needed and avoiding energy waste.

[0037] like Figure 1 and Figure 2 As shown, a limiting plate 103 is provided on the outer side of the drum 101 between each group of heat dissipation components 2, and the two sides of the limiting plate 103 are respectively attached to the outer side of the two annular heat conduction plates 201.

[0038] like Figure 1 and Figure 2As shown, buffer pads 104 are provided on both sides of the limiting plate 103.

[0039] Specifically, by setting a limiting plate 103 between each group of heat dissipation components 2, and the two sides of the limiting plate 103 are respectively attached to the outer sides of the two annular heat-conducting plates 201, the position of the heat dissipation components 2 can be fixed to prevent the components from shifting when the centrifuge body 1 is running at high speed; by setting a buffer pad 104 on both sides of the limiting plate 103, vibration can be absorbed, mechanical wear during equipment operation can be reduced, noise can be reduced, and the service life of the equipment can be extended.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
