However, its liquid alkali pump anti-crystallization device is relatively complicated to operate during use, and it is not easy to clean the components inside the pump. The anti-crystallization treatment effect is not good, so it is necessary to improve the current problems. Utility Model Content

[0005] The utility model aims to provide a liquid alkali pump anti-crystallization device, which has the advantages of high efficiency, good anti-crystallization effect, simple operation and convenient cleaning of the conveying mechanism.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a liquid alkali pump anti-crystallization device, including a support frame, a liquid alkali pump body is arranged on the top of the support frame, an output pipe is arranged on the top of the liquid alkali pump body, a circulation pipe is arranged on the outer surface of the liquid alkali pump body, a suction pipe is arranged at one end of the circulation pipe, a support plate is fixedly connected to the bottom of the liquid alkali pump body, a through groove is opened at the bottom of the support plate, a heating box is fixedly connected to the bottom of the support plate, a heating groove is arranged inside the heating box, and a heat-conducting rod is arranged inside the heating groove.

When the liquid alkali pump body is transporting the liquid alkali or stops transporting the liquid alkali, the heat-conducting rod fixed on the inner wall of the heating tank inside the heating box can be started, and the temperature is increased by the heat-conducting rod. The contact space between the heating box and the bottom of the liquid alkali pump body is increased through the through groove at the bottom of the support plate, so that the temperature inside the heating tank can be transferred to the bottom of the liquid alkali pump body, gradually heating the inside of the body, and preventing the inner wall from crystallizing due to low temperature during long-term transportation of the liquid alkali.

[0008] The utility model is further configured as follows: the top of the support plate is threadedly connected with a first bolt, and the number of the first bolts is several.

[0009] By adopting the above technical solution, the support plate is fixed to the top of the support frame by the first bolt, so that the liquid alkali pump body can be flexibly fixed and disassembled.

[0010] The utility model is further configured as follows: one end of the circulation pipe is fixedly connected to a connecting plate, the outer surface of the connecting plate is provided with a sealing plate, and the outer surface of the sealing plate is threadedly connected to a sealing bolt.

[0015] By adopting the above technical solution, the vibration motor on the top of the support seat can be started to produce a micro-vibration effect on the side of the liquid alkali pump body, further preventing floating objects in the liquid alkali from adhering to the inner wall of the circulation and conveying space of the liquid alkali pump body.

[0016] The utility model is further configured as follows: a lifting rod is arranged on the top of the support frame, and the number of the lifting rods is two.

[0017] By adopting the above technical solution, the setting of the lifting rod can facilitate the provision of an auxiliary transport, transfer and holding mechanism for the support frame, making it more convenient for workers to operate during work.

The utility model, through the coordinated arrangement among the support frame, the liquid alkali pump body, the output pipe, the circulation pipe, the suction pipe, the support plate, the through groove, the heating box, the heating groove and the heat-conducting rod, can make the device in use. Since the liquid alkali pump body is used for a long time to suck and transport the liquid alkali, some of the solid suspended matter contained in the liquid alkali may adhere to the inner wall of the liquid alkali pump body. Therefore, the liquid alkali pump body is supported above the support frame by the support plate. By fixing the heating box at the bottom of the support plate near the center, when the liquid alkali pump body is transporting the liquid alkali or stops transporting the liquid alkali, the heat-conducting rod fixed on the inner wall of the heating groove inside the heating box can be started, and the temperature is increased by the heat-conducting rod. The contact space between the heating box and the bottom of the liquid alkali pump body is increased by the through groove at the bottom of the support plate. Therefore, the temperature inside the heating groove can be transferred to the bottom of the liquid alkali pump body, and the internal temperature is gradually increased and heated, so as to prevent the inner wall from crystallizing due to low temperature during the long-term transportation of the liquid alkali.

[0020] 2. The utility model, through the coordinated arrangement between the connecting plate, the sealing plate, the sealing bolts, the support seat and the vibration motor, can fix the sealing plate and the connecting plate at the end of the suction pipe through the sealing bolts when the device is in use, so that after the conveying operation stops, the connecting plate and the sealing plate can be separated by loosening the sealing bolts to facilitate the cleaning of residual crystals inside each other, and by starting the vibration motor on the top of the support seat, it can have a micro-vibration effect on the side of the liquid alkali pump body, further preventing floating objects in the liquid alkali from adhering to the inner wall of the circulation and conveying space of the liquid alkali pump body.
