Description

Technical Field

[0001] The utility model relates to the technical field of impregnation equipment, in particular to an energy-saving impregnation cleaning wastewater recovery device. Background Art

[0002] The impregnation process uses vacuum pressure impregnation equipment to fully penetrate the impregnation glue (impregnant) into the micropores of the casting, filling the micropore gaps, thereby effectively preventing leakage and corrosion of the casting, and ultimately achieving the purpose of sealing and repairing leaks. After the casting has been impregnated, impregnation liquid will remain on its surface, so the impregnated casting needs to be placed in a cleaning tank for cleaning. At this time, the impregnation liquid on the surface of the casting is mixed into the water of the cleaning tank after washing. If the cleaning water mixed with the impregnation liquid is discharged directly, it will cause environmental pollution, so the impregnation liquid in the cleaning water needs to be filtered. At present, the recovered cleaning water is generally heated. In the filtration method, the cleaning wastewater is added to the treatment equipment, and the impregnation liquid mixed in the water is condensed and solidified by heating. Finally, the water is discharged and the solidified impregnation crystals are filtered out, and the water can be reused. When heating the treatment equipment, a heating mechanism such as a heating rod is generally set inside it. In this heating method, once the heating mechanism stops running, the heat in the treatment equipment will be lost quickly. When the heating treatment is carried out again, the heating work needs to be carried out again to make the temperature inside the treatment equipment reach the fixed temperature of the impregnation liquid. This greatly increases the energy consumption of the heating mechanism and increases the treatment cost. Utility Model Content

[0016] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further described in detail below in combination with the drawings and specific embodiments, and it should be explained that the embodiments and features in the embodiments of the application can be combined with each other without conflict.

[0017] ​In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figures 1-3 As shown, the energy-saving immersion cleaning wastewater recovery device described in this embodiment includes a recovery tank 1, a water inlet 1a is provided on the top of the recovery tank 1, a drain outlet 1b is provided at the bottom of the recovery tank 1, and a number of heating mechanisms 2 are evenly distributed on the inner wall of the recovery tank 1. The recovery tank 1 is provided with a water storage tank 3 at the lower end position of its drain outlet 1b, and a first circulation pump 4 and a second circulation pump 5 are provided in the water storage tank 3. A heating pipe group 6 is provided in the recovery tank 1, and the first circulation pump 4 is connected to the heating pipe group 6 through a water supply pipe 7. The heating pipe group 6 is also provided with a return pipe 8 extending into the water storage tank 3. The second circulation pump 5 pumps the filtered water in the water storage tank 3 to the cleaning equipment through the circulation pipe 9.

[0019] The heating pipe group 6 includes water diversion joints 6a arranged on the front and rear outer walls of the recovery tank 1. Several heating pipes 6b that penetrate the recovery tank 1 are evenly distributed between the water diversion joints 6a on both sides. The water supply pipe 7 and the return pipe 8 are respectively connected to the water diversion joints 6a at both ends.

[0020] A number of heat exchange fins 6c are evenly distributed on the side wall of the heat supply pipe 6b. The heat exchange fins 6c are used to improve the heat dissipation efficiency of the heat supply pipe 6b.

[0021] The heating mechanism 2 includes an outer cover 2a uniformly arranged on the inner wall of the recovery tank 1. A heating rod 2b is arranged inside the outer cover 2a. The heating rod 2b adopts an electric heating method.

[0022] The outer cover 2a is also filled with a heat storage block 2c, and the heating rod 2b is inserted into the heat storage block 2c. The heat storage block 2 is a ceramic heat storage body. The heat storage block 2c can store the heat generated by the heating rod 2b, so that it can quickly heat up the next time it is heated, avoiding excessive temperature loss, thereby saving energy consumption.

[0023] A filter basket 10 is provided in the water storage tank 3 at a position corresponding to the drain outlet 1b. A number of leakage holes 10a are evenly distributed on the filter basket 10. The filter basket 10 filters the solidified leachate in the wastewater. The solidified leachate is blocked inside the filter basket 10, and the filtered water flows into the water storage tank 3 through the leakage holes 10a.

[0024] The water storage tank 3 is symmetrically provided with two support plates 11 on its upper edge. Support edges 10 b are provided on both sides of the filter basket 10 , and the support edges 10 b are hung on the support plates 11 on both sides.

[0025] A control valve 12 is provided at the drain outlet 1b.

[0026] The working principle of the present invention is as follows: the water used to clean the impregnated casting is added to the recovery tank 1 through the water inlet 1a, and the heating rod 2b is started at this time. The heating rod 2b will heat the wastewater in the recovery tank 1. While heating, the heat storage block 2c inside the heating mechanism 2 will store the heat generated by the heating rod 2b. As the temperature of the wastewater continues to rise, the impregnation liquid in the wastewater will condense and solidify. When the impregnation liquid in the water is completely condensed, the control valve 12 is opened, and the treated water is then discharged. The treated water flows along the drain port 1b into the filter basket 10 in the water storage tank 3. The filter basket 10 blocks the solidified impregnation liquid, and the treated water is discharged along the leakage hole 10a on the filter basket 10 and flows into the water storage tank 3. Since the discharged treated water still retains a large amount of heat, The first circulation pump 4 will start and send the hot treated water through the water supply pipe 7 to the water diversion joint 6a on one side, and then be diverted for heat supply through the heating pipe 6b. The heating pipe 6b uses the residual heat in the treated water to provide secondary heat to the inside of the recovery tank 1. At the same time, new wastewater to be treated is added to the recovery tank 1. After the treated water exchanges heat with the inside of the recovery tank 1 through the heating pipe 6b, it is discharged back to the water storage tank 3 through the return pipe 8 of the water diversion joint 6a at the other end. The heating pipe 6b and the heat storage block 2c can perform secondary heating on the inside of the recovery tank 1, thereby maintaining the temperature inside the recovery tank 1. In this way, when heating and filtering, the wastewater in the recovery tank 1 can be quickly heated, which not only improves the filtration efficiency, but also reduces energy consumption, bringing great convenience to production.

[0027] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
