Description

Technical Field

[0001] The utility model relates to the field of pipeline cleaning, in particular to a novel heat exchange spray structure. Background Art

[0002] At present, in some application fields in China, it is necessary to clean the inner wall of the tubular body on some equipment. The cause of the attachment in the tubular body is that a cylinder with a circle of copper strips on the rear edge is placed at one end of the tubular body. When in use, the gunpowder is ignited at the rear end of the cylinder to generate gas. The gas works to push the cylinder to move to the other end of the tubular body. During the movement, a part of the copper strip on the rear edge of the cylinder will be adhered to the inner wall of the tubular body, distributed in various shapes. In this process, gunpowder residue will adhere to the inner wall of the tubular body. Most of these cleaning equipment uses the motor to connect the cleaning parts to the inner wall of the tubular body to clean the attachments. Due to the small space, the heat generated by the motor under long-term working conditions cannot be conducted, resulting in the motor self-locking or burning. Because the attachments in the tubular body are not easy to clean, it is generally combined with the copper removal agent spraying on the surface of the attachments, waiting for decomposition, and then the attachments are cleaned by moving the cleaning equipment in the tubular body. At present, there is no structural equipment in China that combines the functions of motor heat dissipation and copper removal agent spraying. The common copper removal agent spraying cleaning method cannot meet the requirements of simple operation and continuous operation.

[0003] During the cleaning process inside the tubular body, there are currently two solutions for the motor heat dissipation and copper removal agent spraying functions: a split independent solution and a limited working time solution.

[0004] 1. Split independent solution

[0005] This solution is the most widely used. The more common cleaning equipment consists of three parts: cleaning parts, connecting shafts, and power components. During use, after heating the copper remover, first adjust the tubular body to an approximately horizontal state, with the axis of the tubular body at an angle of -5 degrees to the horizontal line, close the drooping end of the tubular body, and introduce the solvent from the relatively high end until it is nearly full. After the whole is left to stand for 1 hour, it is discharged, and then the attachments in the tubular body are cleaned. The power component is placed outside the tubular body, and the heat generated when the motor is working is exchanged with air through the fan of the power component box to cool the motor. In this method, the copper remover needs to be heated in advance, and the copper component of the attachments on the inner wall of the tubular body is decomposed, and then the attachments in the tubular body are cleaned using the cleaning equipment. The split independent solution has high labor intensity and long time for operators. Operators cannot guarantee the continuity, effectiveness and integrity of the cleaning work, and cannot make the equipment reach the best state for reuse.

[0006] 2. Solution to limit working hours

[0007] The cleaning equipment used in this solution combines the cleaning components, connecting shafts, and power components into a whole. This type of equipment is easy to operate and occupies a small area. When cleaning the attachments on the inner wall of a tubular body, the diameter of the cleaning equipment is close to the diameter of the inner wall of the tubular body. Therefore, the heat from the motor during operation cannot be removed by air flow, resulting in the motor overheating and triggering the motor overload protection shutdown after the cleaning equipment has worked for a certain period of time. The cleaning equipment will often stop during the working process to wait for the motor to cool down, and then start working again after the restart conditions are met. With the solution of limited working time, the operator cannot guarantee the continuity of the cleaning work, and cannot combine with the copper removal agent to make the equipment use in the best state. Summary of the invention

[0008] The utility model aims to provide a novel heat exchange spray structure to solve the structural equipment combining the functions of motor heat dissipation and cleaning liquid spraying during the cleaning process, so as to achieve the use requirements of simple operation and continuous work.

[0009] In order to achieve the above purpose, the technical solution of the utility model is:

[0010] A novel heat exchange spray structure comprises a heat conductive jacket spray assembly and a motor. The heat conductive jacket spray assembly is arranged in a pipeline to be cleaned. The heat conductive jacket spray assembly is a hollow cylindrical structure. The motor is fixedly connected to the inside of the heat conductive jacket spray assembly, and a plurality of heat exchange cavities are formed between the outside of the motor and the inner wall of the heat conductive jacket spray assembly. Heat exchange cleaning liquid is injected into the heat exchange cavity, and the heat exchange cleaning liquid is sprayed out from the heat exchange cavity and sprayed onto the inner wall of the pipeline.

[0011] Furthermore, the thermally conductive jacket spray assembly comprises a barrel, a front end cover and a rear end cover, wherein the front end cover is fixedly connected to the front end of the barrel, and the rear end cover is fixedly connected to the rear end of the barrel.

[0012] Furthermore, a reducer connecting shaft is fixedly connected to the power input end of the motor, and the reducer connecting shaft passes through the front end cover.

[0013] Furthermore, a plurality of heat exchange chambers are interconnected, and a connecting rod is fixedly connected to the cylinder body, and the connecting rod connects the heat exchange chamber with the outside.

[0014] Furthermore, the heat exchange chamber is distributed along the length direction of the cylinder body, and a pressure stabilizing chamber is also provided inside the cylinder body. The pressure stabilizing chamber is located between the outlet of the heat exchange chamber and the inner wall of the front end cover.

[0015] Furthermore, a plurality of outlets are provided on the front end cover, and spray nozzles are fixedly connected to the outlets of the front end cover, and the spray nozzles spray cleaning liquid toward the inner wall of the pipeline.

[0016] Furthermore, the cleaning liquid is a copper removal liquid.

After that, the cleaning agent (copper removal liquid) is sprayed on the inner wall surface of the tubular body along the spray nozzle on the heat-conducting jacket spray assembly under the action of pressure difference. During operation, the inner wall of the pipeline can be fully sprayed along the axial section end. Finally, the functions of heating and spraying the cleaning agent (copper removal liquid) and cooling the motor can be simultaneously met through the novel heat-exchange spray structure.
