Description

Technical Field

[0001] This application relates to the technical field of reaction kettles, and particularly to a long-time heat preservation structure for a reaction kettle. Background Art

[0002] A reaction kettle is a device widely used in fields such as chemical engineering, medicine, and materials science, mainly used for chemical reactions, mixing, dissolution, crystallization, distillation and other operations. The structure of the reaction kettle is as shown in the attached Figure 1 specification. It mainly includes a cylinder body, a stirring system, a control system, accessories, etc. In order to achieve the heat preservation effect of the reaction kettle, a jacket outer shell and a heat preservation outer shell are sequentially arranged outside the cylinder body, and a heat preservation layer is arranged between the jacket outer shell and the heat preservation outer shell. The heat preservation layer realizes the heat preservation effect on the cylinder body, avoids the rapid loss of the temperature of the materials in the cylinder body and affects the reaction efficiency, and at the same time reduces the working energy consumption of the reaction kettle.

[0003] The heat preservation layer usually selects heat preservation cotton, such as aluminum silicate rock wool, and fills it between the jacket outer shell and the heat preservation outer shell to achieve effective heat preservation of the cylinder body. During the operation of the reaction kettle, the reaction materials in the cylinder body have a certain temperature, usually higher than the ambient temperature outside the heat preservation outer shell. Therefore, under the influence of the temperature difference and the external environment temperature, condensate droplets will accumulate in the cavity filled with the heat preservation layer between the jacket outer shell and the heat preservation outer shell. The condensate droplets will contact and penetrate into the heat preservation cotton. When the penetration amount is too large, the heat preservation cotton will shrink and harden, resulting in a decrease in the heat preservation effect. At the same time, the overall external dimension of the shrunk heat preservation cotton decreases, as Figure 3 shown in the comparison, and then there are parts in the cavity between the jacket outer shell and the heat preservation outer shell that cannot be filled with heat preservation cotton (such as Figure 4 shown by the dotted line circle in the figure), which further affects the heat preservation effect of the heat preservation layer on the cylinder body, and then affects the working efficiency of the reaction kettle and increases the energy consumption. For this problem, since both the jacket outer shell and the heat preservation outer shell are fixedly connected, such as by welding, it is currently difficult to replace the heat preservation cotton. Summary of the Invention

[0004] Aiming at the above problems, this application aims to provide a long-time heat preservation structure for a reaction kettle, which realizes the relative positioning of the heat preservation layer with the jacket outer shell and the heat preservation outer shell, and at the same time enables the heat preservation layer to return to its normal external dimension, solves the problem that the condensate droplets penetrating into the heat preservation layer increase due to the increase in the number of times the reaction kettle is used, gradually reducing the heat preservation effect of the heat preservation layer, and realizes the long-time heat preservation function of the reaction kettle.

[0005] To achieve the above object, the technical solution adopted by the present application is as follows: A long-time heat preservation structure for a reactor, the reactor includes a cylinder body, an outer jacket shell and a heat preservation shell are sequentially arranged outside the cylinder body, and a heat preservation layer is arranged between the outer jacket shell and the heat preservation shell, and it is characterized in that: positioning mechanisms connected to the heat preservation layer are arranged on both the outer jacket shell and the heat preservation shell, and a self-restoring member for driving the heat preservation layer to recover is arranged on the heat preservation shell.

[0006] Preferably, the positioning mechanism is positioning protrusions uniformly distributed on the inner and outer walls of the outer jacket shell and the heat preservation shell that are close to each other and embedded in the heat preservation layer.

[0007] Preferably, the positioning protrusions on the outer jacket shell and the heat preservation shell are arranged in a staggered manner up and down.

[0008] Preferably, the self-restoring member includes ventilation holes uniformly opened on the heat preservation shell, and detachable plugs are embedded in the ventilation holes.

[0009] The beneficial effect of the present application is that: the relative positioning of the heat preservation layer with the outer jacket shell and the heat preservation shell is realized through the positioning mechanism, which can effectively avoid the problem that the heat preservation layer moves downward in the cavity between the outer jacket shell and the heat preservation shell due to the increased weight caused by the penetration of condensed water, resulting in unfilled parts and affecting the heat preservation effect.

[0010] The self-restoring member can dissipate the condensed liquid droplets penetrating into the heat preservation layer through evaporation, and then the heat preservation layer returns to its normal external dimension, so that the heat preservation layer is fully filled into the cavity between the outer jacket shell and the heat preservation shell, solving the problem that the increased number of times of using the reactor leads to an increase in the condensed liquid droplets penetrating the heat preservation layer, gradually reducing the heat preservation effect of the heat preservation layer, and realizing the long-time heat preservation function of the reactor.

[0020] In order to enable ordinary technicians in the art to better understand the technical solution of this application, the technical solution of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Refer to the Figures 1-9 A long - term heat - preservation structure of a reactor shown in the figure. The reactor includes a cylinder body 1. An outer jacket shell 2 and a thermal insulation outer shell 3 are sequentially arranged outside the cylinder body 1, and a thermal insulation layer 4 is arranged between the outer jacket shell 2 and the thermal insulation outer shell 3. To solve the problem that during the operation of the reactor, condensate droplets accumulate in the cavity filled with the thermal insulation layer between the outer jacket shell and the thermal insulation outer shell, which affects the heat - preservation effect of the thermal insulation layer on the cylinder body, as Figures 6-7 shown in the figure, this application is provided with a positioning mechanism connected to the thermal insulation layer 4 on both the outer jacket shell 2 and the thermal insulation outer shell 3. Through this positioning mechanism, the relative positioning of the thermal insulation layer 4 with the outer jacket shell 2 and the thermal insulation outer shell 3 is realized. That is, when the thermal insulation layer 4 is penetrated by condensate droplets and its weight increases, this positioning mechanism can effectively prevent the thermal insulation layer 4 from moving downward in the cavity between the outer jacket shell 2 and the thermal insulation outer shell 3 due to the increase in weight, so as to avoid the problem that the unfilled part affects the heat - preservation effect.

[0022] During the operation of the reactor, it is inevitable that the thermal insulation layer 4 is penetrated by condensate droplets. Therefore, to solve the problem that after the reactor stops working, the thermal insulation layer can discharge the condensate droplets and restore its own heat - preservation function, as Figure 9 shown in the figure, a self - recovery component for driving the thermal insulation layer 4 to recover is provided on the thermal insulation outer shell 3. This self - recovery component can evaporate and dissipate the condensate droplets that penetrate into the thermal insulation layer 4, thereby enabling the thermal insulation layer to return to its normal external dimensions (such as thickness, height), so that the thermal insulation layer 4 fully fills the cavity between the outer jacket shell 2 and the thermal insulation outer shell 3, solving the problem that as the number of times the reactor is used increases, the number of condensate droplets penetrating the thermal insulation layer 4 increases, gradually reducing the heat - preservation effect of the thermal insulation layer 4, and realizing the long - term heat - preservation function of the reactor.

[0023] Specifically, as Figures 5-7As shown, the positioning mechanism is positioning protrusions a evenly distributed on the inner and outer walls of the jacket housing 2 and the heat preservation housing 3 close to each other and embedded in the heat preservation layer 4. Since the heat preservation layer 4 is made of a flexible soft material, after the heat preservation layer 4 is filled, through the positioning protrusions a of the jacket housing 2 and the heat preservation housing 3, it can be extruded and embedded into the heat preservation layer 4, as Figure 7 shown, when the heat preservation layer 4 is penetrated by condensate droplets and its weight increases, the positioning protrusions a can still ensure the filling position of the heat preservation layer 4, avoiding the problem of voids in the filling caused by its weight increase and subsequent sagging, as well as affecting the heat preservation effect.

[0024] To further improve the positioning effect on the heat preservation layer 4, as Figures 6-8 shown, the positioning protrusions a on the jacket housing 2 and the heat preservation housing 3 are arranged staggered up and down. After the positioning protrusions a arranged staggered up and down are embedded in the heat preservation layer 4, as Figure 8 shown, through the extrusion and embedding of different height positions on the left and right of the heat preservation layer 4, the heat preservation layer 4 is formed into a wavy structure ( Figure 8 shown by the dotted line in), the connection and cooperation of this structure with the positioning protrusions a can further increase the positioning effect of the heat preservation layer 4, avoiding the problem that it sags after its weight increases and flows out of the unfilled area.

[0025] To facilitate the discharge of the condensate droplets penetrating into the heat preservation layer 4 and to restore the heat preservation layer 4, as Figure 9 shown, the self-restoring component includes ventilation holes 3a evenly opened on the heat preservation housing 3, and a detachable plug 5 is embedded in the ventilation holes 3a. When the reactor stops working, the plug 5 is removed to open the multiple ventilation holes 3a, so that the condensate droplets penetrating into the heat preservation layer 4 evaporate and disperse by themselves. After the dispersion, the heat preservation layer 4 in the dry state returns to the initial filling state, enabling it to have a long-term heat preservation effect and solving the problem of the gradually increasing working energy consumption of the reactor.

[0026] The principle of this application is: positioning protrusions a evenly distributed on the inner and outer walls of the jacket housing 2 and the heat preservation housing 3 of the reactor close to each other and embedded in the heat preservation layer 4, and the positioning protrusions a are arranged staggered up and down. The positioning protrusions a can be extruded and embedded into the heat preservation layer 4. When the heat preservation layer 4 is penetrated by condensate droplets and its weight increases, the positioning protrusions a can still ensure the filling position of the heat preservation layer 4, avoiding the problem of voids in the filling caused by its weight increase and subsequent sagging, as well as affecting the heat preservation effect.

[0027] Moreover, ventilation holes 3a are evenly formed in the heat-insulating shell 3, and detachable plugs 5 are embedded in the ventilation holes 3a. When the reactor stops working, the plugs 5 are removed to open the plurality of ventilation holes 3a, so that the condensed liquid droplets permeating in the heat-insulating layer 4 evaporate and dissipate by themselves. After dissipation, the heat-insulating layer 4 in a dry state returns to the initial filling state, enabling it to have a long-term heat-insulating effect and solving the gradually increasing working energy consumption of the reactor.

[0028] The foregoing has shown and described the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application will also have various changes and improvements, and these changes and improvements fall within the scope of the present application claimed.
