Description

Technical Field

[0001] The utility model relates to the field of condensers, in particular to a self-cleaning condenser of asphalt impregnation equipment. Background Art

[0002] Impregnation asphalt refers to asphalt used to impregnate carbon products to reduce the porosity of the products and increase the bulk density or achieve the purpose of impermeability. When impregnating the asphalt, a condenser is required to quickly cool it down.

[0003] The condenser is a type of heat exchanger that can quickly transfer the heat in the tube to the air near the tube. The condensate is mostly water. When water is input from the water inlet pipe, the water will wrap around the inner tube and take away the heat during the flow.

[0004] Since the water used in the condenser does not need to be pure water, it is mostly natural water, and there will be impurities in the water. The impurities can easily clog the filter of the water inlet pipe, requiring frequent manual cleaning, which is time-consuming and labor-intensive. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a self-cleaning condenser for asphalt impregnation equipment.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A self-cleaning condenser for asphalt impregnation equipment comprises an outer sleeve, an inner tube is arranged inside the outer sleeve, a water inlet pipe is arranged on the outer surface of the outer sleeve, a pneumatic ball valve is arranged in the middle of the water inlet pipe, a cleaning pipe is arranged at the connection between the pneumatic ball valve and the water inlet pipe, a first filter plate is fixedly connected to the inner wall of the cleaning pipe on the side close to the water inlet pipe, a transmission rod is movably connected to the middle of the first filter plate, an impeller is fixedly connected to the end of the transmission rod away from the first filter plate, a scraper is fixedly connected to the outer surface of the transmission rod, a bellows is arranged between the cleaning pipe and the water inlet pipe, a central ring is arranged in the middle of the bellows, and a second filter plate is fixedly connected to the inner wall of the central ring.

[0008] Preferably, two water inlet pipes are provided, and two drainage pipes are provided on the outer surface of the outer sleeve, and the water inlet pipe and the drainage pipe are both connected to the inner part of the outer sleeve.

[0009] Preferably, the impeller is arranged inside one end of the cleaning pipe close to the pneumatic ball valve, and the outer surface of the scraper is in contact with the outer surface of the first filter plate.

[0010] Preferably, a sewage pipe is provided on the lower surface of the cleaning pipe, and a piston is provided inside the sewage pipe.

[0011] Preferably, a top block is provided on the outer surface of the second filter plate, and the top block is aligned with the holes of the first filter plate.

[0012] Preferably, a spring is provided on the outer surface of the second filter plate, and one end of the spring away from the second filter plate is fixedly connected to the inner wall of the water inlet pipe.

[0013] The utility model has the following beneficial effects:

[0014] 1. By setting a cleaning pipe in the middle of the water inlet pipe, the cooling water entering the cleaning pipe will drive the impeller to rotate. At the same time, the impeller will drive the scraper to rotate through the transmission rod, thereby cleaning the surface of the first filter plate, which has the effect of automatically cleaning the first filter plate and preventing the debris in the cooling water from clogging the first filter plate;

[0015] 2. By pushing the middle ring, the second filter plate can be driven to approach the first filter plate, which will then drive the top block to penetrate into the holes of the first filter plate to clean up the blocked impurities. After loosening the middle ring, the spring contracts and drives the second filter plate to move backward, thus clearing the blockage. BRIEF DESCRIPTION OF THE DRAWINGS
