Description

Technical Field

[0001] This utility model relates to the field of ion exchange resin production, specifically a heating and heat preservation device for an ion exchange resin reactor. Background Technology

[0002] Existing ion exchange resin production columns are often operated at room temperature, or the indoor temperature of the plant is controlled to ensure room temperature operation of the ion exchange resin column. When it is impossible to guarantee an external room temperature, we need to design an ion exchange resin reactor capable of both heating and insulation. There are several methods for heating during ion exchange resin production: one is to wrap heating pipes around the outside of the reactor, such as the insulation reactor disclosed in CN207137926U. This heating method has low cost, but the heat loss from the outside of the pipes is significant, resulting in serious heat loss and low heating efficiency. Another method is to use a jacketed reactor, indirectly heating the material by introducing hot water or steam into the jacket. Hot water or steam transfers heat to the material inside the reactor, thus raising the temperature. However, long-term heating operations easily lead to scale buildup in the jacket, affecting heating efficiency. Furthermore, cleaning the scale inside the jacket of this type of reactor is very inconvenient and difficult to completely remove. Another method is to use heating rods directly in the reaction system, such as by building heating tubes inside the reactor. This method is more efficient at heating the resin, but the outside of the heating tubes is prone to material adhesion, and the heating tubes need to be cleaned after each use, which is time-consuming and laborious. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model adopts a heating and heat preservation device for an ion exchange resin reactor, which solves the problems of low heating efficiency and difficult cleaning of the existing reactor heating system.

[0004] The technical solution is a heating and heat preservation device for an ion exchange resin reactor, comprising two arc-shaped blocks, left and right. The ends of the two arc-shaped blocks can be fastened together to form an annular block. Each arc-shaped block has a groove on its inner side, and an arc-shaped support plate is fixed in the groove. A guide groove is provided on the support plate, penetrating the inner and outer end faces of the support plate. When the two arc-shaped blocks are fastened together, the two guide grooves can form a continuous spiral groove. A heating pipe is installed in the guide groove, and the two ends of the heating pipe penetrate the right side face of the right arc-shaped block and extend outward from the outer side of the arc-shaped block.

[0005] An arc-shaped heat insulation cavity is provided inside the arc-shaped block on the outside of the settling trough.

[0006] The outer edge of the support plate is spaced apart from the inner side of the sink. The upper and lower end faces of the guide groove are equally spaced with grooves. Each groove contains a ball bearing. The outer end of the ball bearing extends out of the groove and contacts the outer edge of the heating pipe.

[0007] The right end face of the arc-shaped block described on the right side has horizontal holes on the upper and lower sides respectively, which penetrate the inner and outer end faces. The two ends of the heating pipe can pass through the horizontal holes on the upper and lower sides respectively through the arc-shaped block.

[0008] The depth of the settling tank is greater than the outer diameter of the heating pipe.

[0009] The heating pipe is a rubber hose.

[0010] The arc-shaped block is fixed with ribs on the front and rear sides respectively. The ribs are provided with multiple bolt holes at equal intervals from top to bottom, and the bolt holes on the left and right ribs correspond to each other.

[0011] This utility model has the following advantages over the prior art:

[0012] 1. This utility model improves the conventional reactor heating system, making the heating pipe easy to disassemble while blocking external heat dissipation through the arc-shaped block and the heat insulation cavity, thus greatly improving the heating efficiency.

[0013] 2. By setting spiral guide grooves and ball bearings, the movement of the heating pipe is made smoother. The heating pipe can be quickly extracted or installed without disassembling the arc block, which greatly reduces the workload and usage cost of the heating pipe during later maintenance.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Depend on Figures 1 to 5The present invention includes two arc-shaped blocks 1, which can be fastened together to form an annular block. Each arc-shaped block 1 has a groove 2 on its inner side, and an arc-shaped support plate 3 is fixed to the groove 2. The support plate 3 has a guide groove 4 that penetrates the inner and outer end faces of the support plate 3. When the two arc-shaped blocks 1 are fastened together, the two guide grooves 4 can form a continuous spiral groove. A heating pipe 5 is installed in the guide groove 4. The two ends of the heating pipe 5 penetrate the right side surface of the right arc-shaped block 1 and extend outward from the outer side of the arc-shaped block 1.

[0021] An arc-shaped heat insulation cavity 6 is provided inside the arc-shaped block 1 on the outside of the sink 2.

[0022] The outer edge of the support plate 3 is spaced apart from the inner side of the sink 2. The upper and lower end faces of the guide groove 4 are equally spaced with grooves 7. Each groove 7 is provided with a ball 8. The outer end of the ball 8 extends out of the groove 7 and contacts the outer edge of the heating pipe 5.

[0023] The right end face of the arc-shaped block 1 described on the right side has horizontal holes 9 on the upper and lower sides respectively, which penetrate the inner and outer end faces. The two ends of the heating pipe 5 can pass through the horizontal holes 9 on the upper and lower sides respectively through the arc-shaped block 1.

[0024] The depth of the settling tank 2 is greater than the outer diameter of the heating pipe 5.

[0025] The heating pipe 5 is a rubber hose.

[0026] The arc-shaped block 1 is fixed with ribs 11 on the front and rear sides respectively. The ribs 11 are provided with multiple bolt holes at equal intervals from top to bottom, and the bolt holes on the left and right ribs 11 are corresponding.

[0027] The arc-shaped block 1 is provided with annular reinforcing ribs 12 at its upper and lower ends, and the reinforcing ribs 12 can bind and secure the upper and lower sides of the arc-shaped block 1.

[0028] In use, the two arc-shaped blocks 1 are first fastened to the two sides of the reactor, and then the left and right side ribs 11 are connected by bolts to form a continuous ring structure. Hot water is then introduced into the heating pipe 5 to heat the reactor body as a whole until the specified temperature is reached. After that, the hot water flow rate is reduced to keep the tank warm. When hot water is introduced into the heating pipe 5, due to the thermal expansion and contraction of the rubber and metal, the heating pipe 5 fits tightly with the guide groove 4 and the ball bearing 8, making the position of the heating pipe 5 relatively stable inside the arc-shaped block 1, preventing the heating pipe 5 from shifting due to water flow or reactor vibration. When the heating pipe 5 needs to be cleaned, simply wait for the heating pipe 5 to cool down or introduce cold water into the heating pipe 5 to make it shrink. Then pull one end of the heating pipe 5 outward to move it along the guide groove 4 until it is completely pulled out. The heating pipe 5 can then be cleaned or replaced separately, greatly improving the efficiency of replacement or cleaning.

[0029] This invention improves the conventional reactor heating system by making the heating pipe easy to disassemble while blocking external heat dissipation through the arc block 1 and the heat insulation cavity 6, thus greatly improving the heating efficiency. By setting the spiral guide groove 4 and the ball bearing 8, the movement of the heating pipe 5 is made smoother, and the heating pipe 5 can be quickly extracted or installed without disassembling the arc block 1, which greatly reduces the workload and operating cost of the heating pipe 5 during later maintenance.
