Description

Technical Field

[0001] The utility model relates to the technical field of cooling circulation, and further relates to a novel circulating water tank for preparing alumina fibers. Background Art

[0002] During the preparation of sol, a vacuum pump is needed for vacuum concentration. Due to the working principle of the vacuum pump, heat will be continuously generated in the pump body, and long-term high-temperature operation will cause the pump body to deform and damage, affecting the service life and efficiency of the vacuum pump. Therefore, in order to ensure the normal operation of the vacuum pump and reduce the interference and damage of the pump body temperature to the working environment, cooling water needs to be introduced into the vacuum pump for cooling.

[0003] The cooling water mainly achieves the purpose of cooling by exchanging heat with the metal parts inside the pump body. When the cooling water flows through the pump body accessories, it will take away a lot of heat generated inside the pump body and be pumped into the new circulating water tank for alumina fiber preparation through the pipeline.

[0004] The cooling process of cooling water is achieved through a cooling tower. The cooling tower sprays high-temperature water on the packing layer and uses the heat exchange between water and air to complete the heat dissipation, lowering the temperature of the liquid to a set temperature range, and transporting the heat-dissipated water back to the equipment for recycling, so that the water entering the vacuum pump again is cooling water with a lower temperature, because at a lower temperature, the wear of the internal parts of the pump is reduced, and the running resistance is reduced, so as to ensure that the vacuum degree in the reactor is maintained at a high level and improve the vacuuming efficiency. Circulating water in this way not only improves the utilization efficiency of water resources, but also the cooling water can condense the oil vapor generated inside the pump body into liquid, which is conducive to the recycling of the oil in the pump body. In addition, the cooling treatment also helps to reduce the negative impact of the pump body temperature on the working environment. If the cooling water is uniform and the temperature is low, the heat generated by the pump body can be effectively dissipated, reducing the impact of heat radiation on the working environment, helping to maintain the stability of the working environment and protect the health and safety of employees.

[0005] Cooling water plays an important role in vacuum pumps. By introducing cooling water, the temperature of the pump body can be effectively reduced to ensure the normal operation of the vacuum pump. Therefore, when using a vacuum pump, it is necessary to ensure that the cooling water works at a lower temperature to ensure the normal operation of the pump body. During the operation of the new circulating water tank for the preparation of alumina fiber in the vacuum pump, there is a problem of uneven water temperature. This problem has long plagued the vacuum degree of the reactor and has had an adverse effect on the service life of the equipment.

[0006] For technicians in this field, how to improve the uniformity of the cooling water circulation process and avoid the negative impact caused by excessive water temperature differences is a technical problem that needs to be solved at present. Utility Model Content

[0031] The core of the utility model is to provide a new type of circulating water tank for preparing alumina fiber, which is separated by a partition baffle and evenly transports coolant to the low-temperature chamber through a water inlet pipe to ensure that the temperature of the coolant flowing out of each position is more uniform.

[0032] In order to enable those skilled in the art to better understand the technical solution of the utility model, the new circulating water tank for preparing alumina fibers of the utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the utility model provides a new type of circulating water tank for preparing alumina fiber, including a box body 1, a partition baffle 2, a water inlet pipe 3 and other structures. The internal cavity of the box body 1 is used to store water, and acts as a container to temporarily store cooling water in the inner cavity of the box body 1. The box body 1 shown in the figure is a rectangular cavity structure, but it is not limited to this, and can also be a cylindrical shape.

[0034] The partition baffle 2 is arranged in the inner cavity of the box body 1, and the length direction of the partition baffle 2 is arranged along the length direction of the box body 1. The two ends of the partition baffle 2 are respectively fixed to the inner surface of the box body 1, and the lower edge of the partition baffle 2 contacts the bottom surface of the box body 1. The partition baffle 2 separates the inner cavity of the box body 1 into a low-temperature chamber and a high-temperature chamber. The low-temperature chamber and the high-temperature chamber are two relatively independent spaces, but they are not absolutely isolated; Figure 5 The low temperature chamber is located on the left side of the partition baffle 2, and the high temperature chamber is located on the right side of the partition baffle 2. The water temperature in the low temperature chamber is lower than the water temperature in the high temperature chamber.

[0035] The side wall of the low-temperature chamber is provided with a first drain port 11 for supplying cooling water to the vacuum pump. A plurality of first drain ports 11 are provided, and each first drain port 11 is arranged along the length direction of the low-temperature chamber. Each first drain port 11 is connected to a vacuum pump through a pipeline, and the low-temperature cooling water in the low-temperature chamber is transported to the vacuum pump through the first drain port 11. The side wall of the high-temperature chamber is provided with a second drain port 12 for supplying water to the cooling tower. The cooling tower is used to dissipate the heat of the cooling water. The high-temperature cooling water in the high-temperature chamber flows into the cooling tower for heat dissipation and cooling, and the cooled cooling water flows back to the low-temperature chamber. The entire cycle process is: the low-temperature cooling water in the low-temperature chamber flows to the vacuum pump, the high-temperature heating cooling water generated by the vacuum pump, the heated cooling water flows back to the high-temperature chamber, the high-temperature cooling water stored in the high-temperature chamber flows to the cooling tower, the cooling tower dissipates the heat to the outside, re-forms the low-temperature cooling water and flows back to the low-temperature chamber.

[0036] The water inlet pipe 3 is installed on the box body 1, and the axial direction of the water inlet pipe 3 is along the length direction of the box body 1. A plurality of water outlet holes 301 are opened on the side wall of the water inlet pipe 3, and cooling water flows out from the water outlet holes 301. The plurality of water outlet holes 301 are spaced apart along the axial direction; the cooling water transported by the cooling tower is supplied to the low-temperature chamber through the water outlet holes 301, and the cooling water can be evenly discharged from each water outlet hole 301 and evenly reach each position of the low-temperature chamber in the length direction along the length direction. The temperature of the cooling water discharged from each first drain port 11 to the vacuum pump is close, thereby improving the uniformity of the cooling water circulation process, avoiding the negative impact caused by the large difference in the temperature of the cooling water received by the vacuum pump, and each vacuum pump can obtain cooling water at a lower temperature.

[0037] On the basis of the above scheme, a water pressure balance hole 21 is arranged on the partition baffle 2 of the utility model, and the water pressure balance hole 21 connects the low-temperature chamber and the high-temperature chamber. The water passing through the low-temperature chamber and the high-temperature chamber can be circulated through the water pressure balance hole 21 to balance the liquid levels of the low-temperature chamber and the high-temperature chamber. It should be noted that the aperture of the water pressure balance hole 21 is relatively small, and the flow rate of water flowing through the water pressure balance hole 21 is very small, which will not cause the cooling water of the low-temperature chamber and the high-temperature chamber to fully blend, and can still keep the water temperature of the low-temperature chamber lower than the water temperature of the high-temperature chamber. The water pressure balance hole 21 is arranged near the bottom of the partition baffle 2.

[0038] Specifically, the water inlet pipe 3 provided by the utility model is located above the liquid level of the low temperature chamber, and the water inlet pipe 3 is used to spray cooling water from top to bottom. The water inlet pipe 3 is located above the liquid level, and the water outlet 301 is not blocked by the cooling water inside the box 1, and can flow out more smoothly.

[0039] Combination Figure 1 , Figure 5As shown, the water inlet pipe 3 includes an upper pipe 31 and a lower pipe 32. The position of the upper pipe 31 is higher than that of the lower pipe 32. The upper pipe 31 and the lower pipe 32 are arranged parallel to each other. Figure 5 The left and right sides of the middle are located in the middle of the low-temperature chamber; two rows of water discharge holes 301 are set on the upper tube 31, and the two rows of water discharge holes 301 are symmetrically inclined in opposite directions to drain water downward; Figure 6 As shown, the arrow indicates the drainage direction of the water outlet 301, and the drainage directions of the two rows of water outlet holes 301 of the upper tube 31 are respectively directed downward, and the drainage directions of the two rows of water outlet holes 301 are symmetrically arranged about the vertical plane.

[0040] like Figure 6 As shown, two lower tubes 32 are provided, and the two lower tubes 32 are symmetrically distributed about the vertical plane where the upper tube 31 is located. A water discharge hole 301 is provided on each lower tube 32, and one water discharge hole 301 is inclined downward toward the direction of the upper tube 31 to discharge water; the drainage directions of the water outlet holes 301 of the two lower tubes 32 are relatively inclined to discharge water downward, ensuring that the water enters the low-temperature chamber.

[0041] Specifically, one end of the upper tube 31 and the lower tube 32 of the utility model is used for water intake, and the other end can be kept closed, and only one end needs to be supplied with water. The upper tube 31 and the lower tube 32 discharge the cooling liquid outward through a plurality of water outlet holes 301 arranged along the tube wall.

[0042] Specifically, the aperture range of the water outlet hole 301 of the utility model is 5-10 mm; the water outlet hole 301 is inclined downward at 45°±5°, such as Figure 6 As shown, the angle α represents the angle between the water outlet direction of the water outlet hole 301 and the vertical line.

[0043] like Figure 1 , Figure 5 As shown, the height of the partition baffle 2 in the utility model is lower than the inner cavity height of the box body 1. Generally, the water level in the low-temperature chamber and the high-temperature chamber will not be higher than the upper edge of the partition baffle 2. A number of reinforcing plates 4 are vertically fixed on the partition baffle 2, and the two ends of the reinforcing plates 4 are respectively fixed to the inner wall of the box body 1 to enhance the structural strength of the partition baffle 2. A gap for water flow is reserved between the lower edge of the reinforcing plate 4 and the inner bottom surface of the box body 1, that is, the coolant in the low-temperature chamber can flow freely through the gap, and the coolant in the high-temperature chamber can flow freely through the gap without being blocked by the reinforcing plates 4.

[0044] The upper cover of the box body 1 can be removed and opened. Figure 1 In the illustrated embodiment, the box body 1 is surrounded by a bottom surface and four side walls, and the upper cover of the top surface can be disassembled and opened for easy inspection and maintenance.

[0045] The utility model uniformly inputs cooling water into the low-temperature chamber through the water inlet pipe 3 when the cooling water is fed in, which significantly improves the problem of uneven temperature of the circulating cooling water, so that the vacuum degree in the vacuum pump reactor reaches a higher level, the vacuuming efficiency is improved, and the service life of the vacuum pump is increased.

[0046] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
