Description

Technical Field

[0001] The utility model relates to the technical field of preheating, in particular to a preheating device for a circulating pump. Background Art

[0002] A circulating pump is a commonly used water pump. Its function is to circulate the fluid in the pipeline to achieve heating, cooling, filtering, mixing, conveying and other treatments of the fluid. The working principle of a circulating pump is to use the mechanical energy of the pump to suck the liquid from the low-pressure area into the pump, and then push it into the high-pressure area through the movement of the pump, so that it circulates in the pipeline. Specifically, the main components of a circulating pump are the impeller, pump body and motor. The motor provides power to drive the impeller to rotate at high speed, thereby sucking the liquid into the pump and then pushing it into the pipeline.

[0003] When the circulating pump is used in the north or stopped for conveying special liquids, the liquid will crystallize inside the circulating pump. If the circulating pump is suddenly started at this time, the blade resistance in the pump will be large, affecting the service life of the blades. The existing solution is usually to release the liquid in the pump after use so that no liquid is retained inside. This can avoid crystallization of the liquid in the pump, but the discharge is more troublesome. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that when a circulating pump is used in the north or stops for conveying special liquids, the liquid will crystallize inside the circulating pump. At this time, if the circulating pump is suddenly started, the blade resistance in the pump will be large, which will affect the service life of the blades. The existing solution is usually to release the liquid in the pump after use so that no liquid is retained inside the pump, which can avoid the crystallization of the liquid in the pump, but the discharge is more troublesome. A preheating device for a circulating pump is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A preheating device for a circulating pump comprises a pump body, wherein at least three supporting columns are fixedly provided at the bottom of the pump body for supporting the pump body;

[0008] Two arc blocks, the inner sides of the two arc blocks are provided with grooves adapted to the pump body, the grooves are provided with first heating wires, and the first heating wires are in contact with the pump body to heat the outer side of the pump body;

[0009] The transmission mechanism is arranged on the supporting column and is used for driving the heating plate to move upwards and at the same time driving the two arc blocks to approach each other and be clamped on the outer wall of the pump body.

[0014] In a possible design, a plurality of mounting holes are provided on the top of the base for fixing the pump body at the mounting location by bolts.

[0016] When the sliding plate moves upward, it can drive the arc block to approach the pump through the connecting rod until the first heating wire in the arc block contacts the outer wall of the pump. At this time, the first heating wire and the second heating wire are started at the same time to heat the pump body and melt the crystallized liquid in the pump.

[0017] When the liquid in the pump is completely melted, the electric push rod is started again to extend, which can drive the sliding plate to move downward, drive the heating plate away from the bottom of the pump, and at the same time drive the arc block to reset and move away from the outer wall of the pump through the connecting rod.
