Description

Technical Field

[0001] This utility model relates to the field of slurry heating technology, specifically a spiral coil type slurry heating tank. Background Technology

[0002] Slurry is a semi-solid substance composed of a mixture of powdered materials and liquid. It is commonly used in the manufacture of ceramics, glass, building materials, electronic components and other fields. When heating slurry, a heat exchange device is required for heat exchange.

[0003] Announcement No.: CN209558959U, entitled "A Heat Exchanger for Solid Slurry", consists of a cleaning inlet, a material inlet pipeline, a material inlet, a circulating water outlet, a material outlet, a cleaning outlet, a circulating water inlet, a sleeve, branch pipes, an inner pipe, a support frame, support blocks, and U-shaped fittings. It is suitable for solid slurries with a solid content of 8%-18%, and features good pipeline stability, simple structure, pressure resistance, high reliability, and simple manufacturing. It can prevent the pipeline from being blocked by hair, fibers, and other substances. It is also equipped with a cleaning inlet and a cleaning outlet, which can clean the pipeline at any time, making it convenient for use and maintenance.

[0004] The existing slurry heating tank coil adopts a top-inlet and bottom-outlet structure, which easily leads to slurry sticking to the wall and pipe blockage. In addition, the insulation is poor, which easily leads to uneven heating and further exacerbates the risk of slurry sticking to the wall and pipe blockage. Therefore, it does not meet the existing requirements, so a spiral coil slurry heating tank is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a spiral coil type slurry heating tank to solve the problems mentioned in the background art, which are that the existing slurry heating tanks adopt a top-inlet and bottom-outlet structure, which easily leads to slurry sticking to the wall and pipe blockage, and the poor heat preservation performance easily leads to uneven heating, further aggravating the risk of slurry sticking to the wall and pipe blockage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spiral coil type slurry heating tank, comprising: a heating tank body, an insulation cotton layer provided on the outer wall of the heating tank body, a color steel tile layer provided on the outside of the insulation cotton layer, a coil assembly provided inside the heating tank body, the coil assembly including a spiral coil body, a slurry inlet provided at the lower end of the spiral coil body, and a slurry outlet provided at the upper end of the spiral coil body.

[0007] Preferably, the spiral coil body is provided with a support frame inside, and the support frame is connected to the spiral coil body by a U-shaped clamp.

[0008] Preferably, one end of the slurry inlet is connected to a pump body via a pipeline.

[0009] Preferably, the outer wall of the heating tank body is provided with a hot water inlet and a hot water outlet, and one end of the hot water inlet and the hot water outlet extends into the heating tank body.

[0010] Preferably, the spiral coil body is made of seamless stainless steel tubing.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The main body of the heating tank of this utility model adopts a double-layer structure of inner and outer insulation cotton layer and color steel tile layer. The coil assembly is located inside, and the slurry is located inside the coil assembly. The slurry moves from bottom to top, spiraling upward through the spiral coil. Hot water is also provided inside the tank. During the heating process, the hot water transfers heat to the spiral coil, heating the slurry. Through this structure, the heat transfer of hot water to the outside can be reduced, greatly improving the heat preservation performance of the heating tank. This makes the slurry more uniform during the heating process and less likely to cause uneven heating of the slurry or pipe blockage due to excessively rapid temperature drop.

[0013] 2. The spiral coil design enables the slurry to rotate rapidly during operation, resulting in uniform heating and more stable production. The spiral coil uses a bottom-in, top-out heat exchange method, which prevents the slurry from sticking to the wall, caking, or clogging the tube, and also makes the heating efficiency of the slurry higher.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1-4 This utility model provides an embodiment of a spiral coil type slurry heating tank, comprising: a heating tank body 1, an insulation cotton layer 101 provided on the outer wall of the heating tank body 1, a color steel tile layer 103 provided on the outside of the insulation cotton layer 101, a coil assembly 2 provided inside the heating tank body 1, the coil assembly 2 including a spiral coil body 202, a slurry inlet 204 provided at the lower end of the spiral coil body 202, a slurry outlet 205 provided at the upper end of the spiral coil body 202, a hot water inlet 102 and a hot water outlet 104 provided on the outer wall of the heating tank body 1, and one end of the hot water inlet 102 and the hot water outlet 104 extending into the heating tank body 1; the hot water inlet 102 and the hot water outlet 104 are respectively used for supplying hot water for inlet and outlet operations;

[0021] The main body 1 of the heating tank adopts a double-layer structure of inner and outer insulation cotton layer 101 and color steel tile layer 103. The coil assembly 2 is located inside the tank, and the slurry is located inside the coil assembly 2. The slurry moves from bottom to top and rises in a spiral manner through the spiral coil. Hot water is also provided inside the tank. During the heating process, the hot water transfers heat to the spiral coil to heat the slurry. Through this structure, the heat transfer of hot water to the outside can be reduced, which greatly improves the heat preservation performance of the heating tank and makes the slurry more uniform during the heating process. It is not easy for the temperature to drop too quickly, which could cause uneven heating of the slurry or pipe blockage.

[0022] Among them, the insulation cotton has good heat preservation performance, which can effectively improve the heat preservation performance of the heating tank and make it less likely for the temperature of the hot water inside the tank to be transferred outward.

[0023] Specifically, the spiral coil body 202 has a support frame 201 inside, which is connected to the spiral coil body 202 by a U-shaped clamp. The lower end of the spiral coil body 202 has a slurry inlet 204, one end of which is connected to a pump body 203 via a pipeline. The upper end of the spiral coil body 202 has a slurry outlet 205. The spiral coil design allows the slurry to rotate rapidly during operation, resulting in uniform heating and more stable production. The spiral coil uses a bottom-in, top-out heat exchange method, which prevents the slurry from sticking to the wall, caking, or clogging the pipe, and also makes the slurry heating efficiency higher.

[0024] The spiral coil body 202 is made of seamless stainless steel tube, which is not easy to rust and generate impurities, and can achieve better thermal conductivity and service life.

[0025] Working principle: The main body 1 of the heating tank adopts a double-layer structure of inner and outer insulation cotton layer 101 and color steel tile layer 103. The coil assembly 2 is located inside the tank, and the slurry is located inside the coil assembly 2. The slurry moves from bottom to top and rises in a spiral manner through the spiral coil. Hot water is also provided inside the tank. During the heating process, the hot water transfers heat to the spiral coil, heating the slurry. Through this structure, the heat transfer of hot water to the outside can be reduced, which greatly improves the heat preservation performance of the heating tank and makes the slurry more uniform during the heating process. It is not easy for the temperature to drop too quickly, which may cause uneven heating of the slurry or pipe blockage.

[0026] The pump body 203 moves the slurry from the inlet 204 to the outlet 205 by pumping. The spiral coil design enables the slurry to rotate rapidly during operation, resulting in uniform heating and more stable production. The spiral coil uses a bottom-in, top-out heat exchange method, which not only prevents the slurry from sticking to the wall, caking, or clogging the pipe, but also makes the heating efficiency of the slurry higher.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
