Description

Technical Field

[0001] This utility model relates to the field of cooling towers, and in particular to a high-pressure blower and a high-efficiency dual-purpose cooling tower. Background Technology

[0002] A forced-air cooling tower is an industrial cooling device that uses a bottom fan to force air in for heat exchange. The blower is installed at the bottom of the forced-air cooling tower to blow outside air into the tower, causing the gas to be treated to move upward and come into contact with the reactants. It can also be used to extract air from electrolysis workshops to achieve the required air exchange frequency, thereby improving the workshop working environment and cooling the workshop temperature.

[0003] In the electrolytic zinc industry, blast cooling towers need to meet both cooling and demisting requirements. Since the gas inside the blast cooling tower is usually corrosive, it can easily corrode the blower, requiring regular maintenance. Furthermore, the blower needs to be modified under different seasonal operating conditions, or the spray material of the blast cooling tower needs to be adjusted according to the operating conditions. However, the blower is usually an integrated unit, making maintenance or adjustment difficult. In addition, different spray materials inside the blast cooling tower may produce chemical reactions and cannot coexist. Utility Model Content

[0004] This utility model aims to provide a high-pressure blower and a high-efficiency dual-purpose cooling tower to solve the adjustment needs of the blower and sprayed materials under different seasonal working conditions, as well as the maintenance needs of the blower.

[0005] To achieve the above objectives, the present invention provides a high-pressure blower comprising a drive assembly, a blower body, and a blower casing. The output end of the drive assembly is connected to the shaft of the blower body. Multiple sections of the blower casing are detachably connected to each other and are fitted onto the outside of the drive assembly and the blower body.

[0023] To make the objectives and technical solutions of the present utility model embodiments clearer, the following will be described in conjunction with the accompanying drawings of the present utility model embodiments. Figure 1 - Appendix Figure 4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] In this utility model, for clarity, the following description is provided: [The observer faces the attached...] Figure 1 Upon observation, the descriptions of "top," "bottom," etc., in this utility model are all attached. Figure 1 For reference only. The above description is only for the purpose of clearly describing the present invention, and is not intended to indicate or imply that the structure or component referred to must have a specific orientation or be constructed in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0025] like Figure 1 As shown, the high-efficiency dual-purpose cooling tower 1 is used for cooling and demisting. The high-pressure blower 2 is installed at the bottom of the cooling tower 1. The blower 2 blows the air outside the cooling tower 1 into the interior of the cooling tower 1, causing the waste gas to be treated to move upward and react with the reactants, and cooling down the internal temperature of the cooling tower 1.

[0026] The cooling tower 1 includes a tower body 11, an air inlet 12, a first spray device 13, and a second spray device 14. The air inlet 12 is opened at the bottom of the tower body 11, and the blower 2 is fixedly installed in the air inlet 12. At least one set of the first spray device 13 and the second spray device 14 is installed in the upper section of the tower body 11. Other components in the cooling tower 1 are configured according to actual use. For example, if it is to treat waste gas and make the reaction complete, a packing layer (not shown in the figure) can be set to increase the contact area between the waste gas and the sprayed material.

[0027] The first spray device 13 and the second spray device 14 have the same structure. Taking the first spray device 13 as an example, the first spray device 13 includes a pipe 131 and a spray head 132. The pipe 131 passes through the tower body 11 and is fixed. At least one end of the pipe 131 is an inlet. The spray material is transported into the pipe 131 from the inlet. A plurality of spray heads 132 are evenly arranged on the pipe 131. The spray heads 132 spray the spray material evenly, so that the spray material is in full contact with the gas.

[0028] The spray materials sprayed by the first spray device 13 and the second spray device 14 can be different materials, which can be liquids or gases. The first spray device 13 and the second spray device 14 are respectively connected to different circulation systems. Because the chemical components in different spray materials may react in the same spray device, causing corrosion to the pipeline 131, the spray materials cannot be directly replaced in the same spray device; or spraying needs to be carried out at different times. For example, the first spray device 13 sprays process liquids, and the second spray device 14 sprays corrosive gases. The second spray device 14 needs to spray again after the first spray device 13 stops spraying, to wash away acid mist and dust in the gas. Figure 1 As shown, one end of the blower 2 is installed at the air inlet 12, and the other end is connected to the exhaust pipe (not shown in the figure). Please refer to... Figures 2-4 The blower 2 includes a support 21, a drive assembly 22, a protective cover 23, a support member 24, a coupling 25, and a blower body 26. The drive assembly 22 is fixedly mounted on the top of the support 21, and the protective cover 23 is fitted over the drive assembly 22. The support member 24 is mounted on the top of the support 21, and is aligned with the drive assembly 22. The top of the support member 24 is at the same height as the output end of the drive assembly 22. One end of the coupling 25 passes through the protective cover 23 and connects to the output end of the drive assembly 22. The other end of the coupling 25 is connected to the shaft of the blower body 26. The drive assembly 22 drives the blower body 26 to rotate via the coupling 25. The blower body 26 is located inside the air inlet 12.

[0029] Specifically, the support 21 is preferably made of stainless steel and is fixed to the ground by pre-embedded welding, and the top of the support 21 is flat.

[0030] Specifically, the protective cover 23 is used to protect the drive assembly 22 and prevent the drive assembly 22 from being corroded by exhaust gas and dust from affecting the operation of the drive assembly 22, and the support member 24 is used to support the coupling 25.

[0031] like Figure 3 As shown, the blower 2 also includes a blower duct 27 and a flange 28. Multiple blower ducts 27 are sequentially and detachably connected, fitted onto the outside of the drive assembly 22, the coupling 25, and the blower body 26. Adjacent blower ducts 27 are connected via the flange 28. The blower ducts 27 protect the internal structure of the blower 2, and the flanges 28 secure the connection between adjacent blower ducts 27. During subsequent maintenance or adjustment, the internal components of the blower 2 can be repaired or adjusted by disassembling the corresponding flange 28 and blower duct 27.

[0032] like Figure 4 As shown, in order to stabilize and reduce the flutter generated when the fan body 26 rotates, the bracket 29 can also be fixedly installed at the bottom of the air duct 27 fitted on the outside of the fan body 26, and the bottom of the bracket 29 is fixed to the inner wall of the air inlet 12; in another embodiment, the bracket 29 can be omitted, and the air duct 27 fitted on the outside of the fan body 26 can be directly fixed to the inner wall of the air inlet 12.

[0033] Specifically, in order to facilitate monitoring of the working status of the blower 2, monitoring and alarm devices can also be installed on the blower 2, such as blade anti-collision alarm devices, fan vibration alarm devices, oil temperature alarm devices, motor temperature rise alarm devices, etc.

[0034] The high-pressure blower provided by this utility model can be disassembled and installed in sections through the air duct and flange, which facilitates the maintenance of the blower and the adjustment of components according to working conditions. Furthermore, by designing two independent spray devices in the cooling tower, different spray materials can be used, which broadens the application range and is suitable for different working needs.

[0035] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
