Description

Technical Field

[0001] This utility model belongs to the field of jacket technology, specifically, it relates to a sanitary tank jacket purging residual liquid. Background Technology

[0002] In applications such as reaction vessels, homogenizers, and mixing tanks used for material mixing or chemical reactions, certain temperature conditions are often required. The jacket design can effectively exchange heat with the material in the tank, thereby ensuring that the temperature inside the tank meets the usage requirements.

[0003] Patent CN212227846U discloses a jacket device, which forms a first cavity by means of a first partition, an inner cylinder, and an outer cylinder. The first partition and the second partition enhance the strength of the jacket device, reduce the design wall thickness of the inner cylinder of the jacket device, and improve the heat transfer efficiency of the medium inside the jacket device.

[0004] In the above-mentioned patented technical solution, the strength of the jacket is improved by only the first and second separators, resulting in a longer service life. However, in actual application, since the internal tank structure needs to exchange heat through media of different temperatures, the thermal expansion and contraction caused by strong temperature difference changes is one of the main causes of jacket damage. Improving the strength of the jacket device alone is not enough to significantly improve the service life of the jacket, which has certain limitations. Utility Model Content

[0005] To address the technical problem in the prior art where jackets are easily damaged by rapid temperature changes during use, leading to severe thermal expansion and contraction and a significant reduction in their service life, this invention provides a sanitary tank jacket purging device for residual liquid.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A sanitary tank jacket purging residual liquid device includes a tank; a jacket is connected to the outer surface of the tank via a flange; and a connecting guide pipe is fixed to the upper and lower sides of the jacket, with the upper guide pipe used for discharging the medium and the lower guide pipe used for introducing the medium.

[0008] The upper guide pipe is connected to a high-temperature medium outlet pipe, a normal-temperature medium outlet pipe, and a low-temperature medium outlet pipe via a four-way pipe;

[0009] The flow guide pipe located below is connected to a high-temperature medium inlet pipe, a normal-temperature medium inlet pipe, and a low-temperature medium inlet pipe via a four-way pipe.

[0010] Furthermore, the upper guide pipe is fixedly connected to a first branch pipe at a position corresponding to the position between the safety valve and the first valve;

[0011] The lower guide pipe is fixedly connected to a second branch pipe at the position between the manual valve and the first valve.

[0012] Furthermore, the first branch pipe is respectively provided with a one-way valve and a second valve, the one-way valve is located below the second valve, and the second valve is a pneumatic valve.

[0013] Furthermore, a third valve, which is a pneumatic valve, is connected to the second branch pipe.

[0014] Furthermore, a safety valve is connected to the upper guide pipe; a manual valve is connected to the lower guide pipe.

[0015] Furthermore, a first valve is provided on each of the high-temperature medium outlet pipe, the normal-temperature medium outlet pipe, the low-temperature medium outlet pipe, the high-temperature medium inlet pipe, the normal-temperature medium inlet pipe, and the low-temperature medium inlet pipe. The first valve is a pneumatic valve.

[0016] Furthermore, a head is connected to the top of the tank; a water supply pipe connecting to the inside of the tank is fixedly connected to the center of the top of the head; a cleaning ball is fixedly connected to the lower end of the water supply pipe; and a vent is fixedly connected to the head.

[0017] Furthermore, a discharge pipe communicating with the interior of the tank is fixedly connected to the center of the bottom of the tank.

[0018] Furthermore, three legs arranged in a circular array are fixed to the bottom periphery of the tank.

[0019] The beneficial effects of this utility model are:

[0020] 1) When the equipment is first started, if the initial temperature of the jacket is low, the temperature of the medium introduced into the jacket can be gradually increased by using three different temperature media in combination until the required working temperature is reached. This slows down the thermal expansion and contraction process of the jacket and avoids rapid deformation of the jacket, which would lead to a significant reduction in service life.

[0021] 2) When the tank inside the jacket is used for heat exchange and insulation, if the tank needs different temperatures, the discharge of different temperature media can be controlled by the first valve to keep the temperature at the operating temperature of the tank, which is convenient for the tank to work and use.

[0022] 3) This utility model uses compressed air to purge the inside of the jacket. By utilizing the high pressure and flow rate of the compressed air, the residual liquid is forcibly discharged from the second branch pipe to the outside of the jacket. Through this compressed air purging method, the residual liquid inside the jacket can be discharged, ensuring that the inside is clean and dry, making the temperature change of the jacket more uniform, reducing the loss of the jacket caused by thermal expansion and contraction, and reducing the damage to the jacket caused by thermal expansion and contraction, corrosion and other damages caused by residual media.

[0039] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below:

[0040] Because the lower part of the jacket 3 of the tank body 1 is connected to three medium inlet pipes of different temperatures via a four-way pipe, namely high temperature medium inlet pipe 13, normal temperature medium inlet pipe 14, and low temperature medium inlet pipe 15, and the upper part of the jacket 3 of the tank body 1 is connected to three medium outlet pipes of different temperatures via a four-way pipe, namely high temperature medium outlet pipe 10, normal temperature medium outlet pipe 11, and low temperature medium outlet pipe 12, when heat exchange and insulation of the tank body 1 inside the jacket 3, if the tank body 1 needs different temperatures, the discharge volume of different temperature media can be controlled by the first valve 16 to keep the temperature at the operating temperature of the tank body 1. For example, by opening the first valve 16 of the high temperature medium inlet pipe 13 and the normal temperature medium inlet pipe 14, the media of different temperatures can be simultaneously introduced into the jacket 3 through the guide pipe 9 located below, so that a medium of suitable temperature can be obtained, and then discharged from the normal temperature medium outlet pipe 11. This is convenient for the operation and use of the tank body 1.

[0041] When the equipment is first started, if the initial temperature of the jacket 3 is low, the temperature of the medium introduced into the jacket 3 can be gradually increased by using three different temperature media in combination until the required working temperature is reached. This slows down the thermal expansion and contraction process of the jacket 3 and prevents the jacket 3 from deforming rapidly, which would significantly reduce its service life.

[0042] Furthermore, since the upper guide pipe 9 is connected to the first branch pipe 17 and the lower guide pipe 9 is connected to the second branch pipe 171, air is compressed by an air compressor or other equipment, and the compressed air is discharged from the first branch pipe 17 into the upper guide pipe 9. Then, the compressed air is used to purge the inside of the jacket 3. The high pressure and flow rate of the compressed air forcefully discharge the residual liquid from the second branch pipe 171 to the outside of the jacket 3. Through this compressed air purging method, the residual liquid inside the jacket 3 can be discharged, ensuring that the inside is clean and dry, making the temperature change of the jacket 3 more uniform, reducing the loss of the jacket 3 of the tank 1 caused by thermal expansion and contraction, and reducing the damage to the jacket 3 caused by thermal expansion and contraction, corrosion and other damage caused by residual media.
