Description

Technical Field

[0001] This utility model belongs to the field of circulating pump technology, specifically relating to a separate impeller for an absorption tower circulating pump. Background Technology

[0002] Absorption tower circulating pumps are widely used in gas absorption and treatment processes in industries such as chemical, metallurgy, and power, especially in absorption towers for liquid circulation and gas-liquid mixing. The operating environment of these pumps typically requires high corrosion resistance and high temperature resistance, as well as long-term, high-efficiency operation.

[0003] In existing circulating pumps, the impeller and shaft sleeve are generally integrated. During long-term high-temperature operation, the outer material of the shaft sleeve will gradually wear down with high-speed operation, resulting in acid leakage. Since the impeller and shaft sleeve are integrated, it will lead to high maintenance costs.

[0004] Therefore, a separate impeller for the absorption tower circulating pump is proposed. By pressing the stop block and squeezing the spring, the stop block moves along the inner wall of the second tank, thereby separating the blade from the sleeve. In subsequent maintenance, only the corresponding parts need to be replaced individually. Utility Model Content

[0005] To overcome the problem that existing circulating pumps generally use an integrated impeller and shaft sleeve, which can lead to acid leakage due to the gradual wear of the outer material of the shaft sleeve during long-term high-temperature operation and high-speed rotation, and the high maintenance cost caused by the integrated impeller and shaft sleeve, a separate impeller for the absorption tower circulating pump is proposed.

[0006] The technical solution of this utility model is as follows: a separate impeller for an absorption tower circulating pump, including a base plate; it also includes a sleeve and a fixing component; the upper end of the base plate is fixedly connected to the sleeve, and multiple first grooves are opened through the outer wall of the sleeve; a connecting plate is slidably arranged on the inner wall of the first groove; a second groove is opened at the lower edge of the connecting plate; a slider is slidably arranged on the inner wall of the second groove; a telescopic rod is fixedly connected to the top of the inner wall of the second groove; the other end of the telescopic rod is fixedly connected to the upper end of the slider; a spring is sleeved on the outer wall of the telescopic rod; and a stop block is fixedly connected to the lower end of the slider.

[0007] Preferably, the outer wall of the stop block is fitted to the inner wall of the sleeve, a blade is fixed to the outer side of the connecting plate, the blade is arc-shaped, and a sealing ring is fixed to one end of the connecting plate near the blade, with the inner side of the sealing ring fitting to the outer wall of the sleeve.

[0008] Preferably, a third groove is provided at the upper end of the base plate, and a limiting plate is fixedly connected to the lower end of the blade, with the limiting plate being compatible with the third groove.

[0009] Preferably, a bushing is fixed to the inner wall of the base plate, and a fixing component is provided on the outer wall of the bushing. The fixing component includes an upper cover plate, a sealing cover, and a fixing bolt. An upper cover plate is provided at the upper end of the blade, and a fixing bolt is provided at the upper edge of the upper cover plate. The other end of the fixing bolt is threaded into the inside of the blade.

[0010] Preferably, a sealing cap is threaded onto the inner wall of the sleeve, the inner wall of the sealing cap is in contact with the outer wall of the bushing, and the lower end face of the sealing cap is in contact with the upper end face of the upper cover plate.

[0011] Preferably, a rotating shaft is slidably disposed inside the bushing, and a fixing cover is threadedly installed on the upper end of the rotating shaft, with the lower end face of the fixing cover fitting against the upper end face of the sealing cover.

[0012] Preferably, a limiting rod is fixed to the outer wall of the shaft, and a limiting groove is opened at the edge of the outer wall of the bushing, with the limiting rod and the limiting groove being compatible.

[0013] The beneficial effects of this utility model are as follows: by pressing the stop block to compress the spring, the stop block enters the inner wall of the second groove, and then the blade is pulled out of the first groove, so that the blade is separated from the sleeve. In subsequent maintenance, only the corresponding parts need to be replaced, instead of replacing the entire impeller, which reduces maintenance costs and simplifies the maintenance process. It also solves the problem that the integrated design of the impeller and the bushing leads to high subsequent maintenance costs. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5 This utility model provides an embodiment of a separate impeller for an absorption tower circulating pump, including a base plate 1; it also includes a sleeve 101 and a fixing assembly; the sleeve 101 is fixedly connected to the upper end of the base plate 1, and a plurality of first grooves 102 are formed through the outer wall of the sleeve 101. A connecting plate 104 is slidably arranged on the inner wall of the first groove 102, and a second groove 105 is formed at the lower edge of the connecting plate 104. A slider 106 is slidably arranged on the inner wall of the second groove 105, and a telescopic rod 107 is fixedly connected to the top of the inner wall of the second groove 105 for telescopic movement. The other end of the rod 107 is fixed to the upper end of the slider 106. A spring 108 is sleeved on the outer wall of the telescopic rod 107. A stop block 109 is fixed to the lower end of the slider 106. By pressing the stop block 109, the spring 108 is compressed, and the stop block 109 enters the inner wall of the second groove 105. Then, the blade 103 is pulled out from the first groove 102, so that the blade 103 is separated from the sleeve 101. In subsequent maintenance, only the corresponding parts need to be replaced. This solves the problem that the integrated design of the impeller and the bushing 2 leads to a large subsequent maintenance cost.

[0022] Please see Figure 2 and Figure 5 In this embodiment, the outer wall of the stop 109 is in contact with the inner wall of the sleeve 101. A blade 103 is fixedly connected to the outer side of the connecting plate 104. The blade 103 is arc-shaped. A sealing ring 110 is fixedly connected to one end of the connecting plate 104 near the blade 103. The inner side of the sealing ring 110 is in contact with the outer wall of the sleeve 101. A third groove 111 is provided at the upper end of the bottom plate 1. A limiting plate 112 is fixedly connected to the lower end of the blade 103. The limiting plate 112 is adapted to the third groove 111. By setting the sealing ring 110, liquid leakage can be effectively avoided and wear can be reduced during use, thereby improving the sealing performance and service life of the equipment. The cooperation between the limiting plate 112 and the third groove 111 can prevent the blade 103 from being unstable or moving excessively during use, thereby ensuring the normal operation of the blade 103.

[0023] Please see Figure 4In this embodiment, a bushing 2 is fixedly connected to the inner wall of the base plate 1, and a fixing component is provided on the outer wall of the bushing 2. The fixing component includes an upper cover plate 201, a sealing cover 202, and a fixing bolt 203. An upper cover plate 201 is provided on the upper end of the blade 103, and a fixing bolt 203 is provided at the upper edge of the upper cover plate 201. The other end of the fixing bolt 203 is threaded to the inside of the blade 103. A sealing cover 202 is threadedly installed on the inner wall of the sleeve 101. The inner wall of the sealing cover 202 fits against the outer wall of the bushing 2, and the lower end face of the sealing cover 202 fits against the upper end face of the upper cover plate 201. By rotating the fixing bolt 203, the upper cover plate 201 and the blade 103 can be fixed together, ensuring that the blade 103 will not loosen or shift during use, which helps to ensure the stability of the blade 103 and the safety of the system.

[0024] Please see Figure 1 In this embodiment, a rotating shaft 3 is slidably disposed inside the bushing 2. A fixing cover 6 is threadedly installed on the upper end of the rotating shaft 3. The lower end face of the fixing cover 6 is in contact with the upper end face of the sealing cover 202. A limiting rod 4 is fixedly connected to the outer wall of the rotating shaft 3. A limiting groove 5 is opened at the edge of the outer wall of the bushing 2. The limiting rod 4 and the limiting groove 5 are adapted to each other. The lower end face of the fixing cover 6 is in close contact with the upper end face of the sealing cover 202, forming a sealing structure that effectively prevents the leakage of liquid or gas. When the rotating shaft 3 moves, the limiting rod 4 will cooperate with the limiting groove 5 to limit the movement range of the rotating shaft 3.

[0025] In use, the impeller is separated from the shaft 3 by rotating the fixed cover 6. Then, the upper cover 201 is separated from the blade 103 by rotating the sealing cover 202 and the fixing bolt 203. Then, the stop block 109 is pressed to compress the spring 108, so that the stop block 109 enters the inner wall of the second groove 105. Then, the blade 103 is pulled out from the first groove 102, so that the blade 103 is separated from the sleeve 101. In subsequent maintenance, only the corresponding parts need to be replaced. This solves the problem that the integrated design of the impeller and the shaft sleeve 2 would lead to a large subsequent maintenance cost.
