Description

Technical Field

[0001] The utility model specifically relates to a feeding anti-blocking device for spraying quick-setting rubber asphalt waterproof coating, and belongs to the technical field of waterproof coating production. Background Art

[0002] The main components of the spray quick-setting rubber asphalt waterproof coating are composed of more than two high-performance modified emulsified rubber asphalts and chemical accelerating catalysts. When the waterproof coating is produced, the components are controlled at temperature and fully mixed to obtain the coating. When used later, the waterproof coating is sprayed with a high-pressure nozzle. If there are impurities in the raw materials, the high-pressure nozzle is easily blocked. For this reason, the Chinese patent announcement number: CN217016481U discloses a feed anti-blocking device for spray quick-setting rubber asphalt waterproof coating, including a box body; a vibration component, the bottom of which is fixedly connected to the top of the box body. The device moves the feed barrel up and down by moving the moving plate up and down, thereby effectively avoiding the problem of raw material blockage during feeding, and can effectively improve the efficiency of raw material mixing. The above structure can facilitate the feeding of the feed barrel, but it cannot filter out impurities in the components. In addition, since the waterproof coating contains emulsified rubber asphalt components, it has a certain viscosity. The filter structure is used for slow feeding and is easy to cause the coating raw material components to block the filter. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a feed anti-clogging device for spraying quick-setting rubber asphalt waterproof coating, which can filter out impurities from raw material components and ensure the efficiency of viscous components in the waterproof coating passing through the filter.

At the same time, the medium frequency heater forms an eddy current in the metal mesh plate, thereby directly heating the metal mesh plate, and the coating components in contact with the metal mesh plate are directly heated, so that they can quickly pass through the filter holes of the metal mesh plate.

[0013] Furthermore, the heater is a steam heater, and the steam heater includes a steam inlet flange and a drain flange installed on the upper and lower parts of the heating sleeve; the steam inlet flange and the drain flange are connected to the steam heating unit; a partition is fixed between the steam inlet flanges inside the heating sleeve, and a connecting hole is opened at one end of the partition away from the drain flange; when the heater is working, the steam heating unit injects a certain amount of steam into the steam inlet flange, the steam enters the heating sleeve, and after heat exchange between the heating sleeve and the anti-blocking component, the steam is liquefied, flows to the drain flange through the connecting hole, and re-enters the steam heating unit through the drain flange for secondary heating; the heated components carry heat into the production kettle, are subjected to secondary temperature control through the production kettle, and are mixed and reacted with other components.

[0014] Furthermore, the hose includes an upper hose and a lower hose; the upper bowl is connected to the upper hose through a flange, and the upper hose is connected to the feed valve group; the lower bowl is connected to the lower hose through a flange, and the lower hose is connected to the production kettle; when working, the material pump pumps a certain amount of raw material components into the upper hose through the feed valve group, then enters the upper bowl, and enters the lower bowl through the filter plate. After the viscous components are heated to increase fluidity, they enter the lower bowl and are then added to the production kettle through the lower hose.

[0015] Furthermore, a sealing gasket ring is provided between the upper bowl and the upper hose, and a sealing gasket ring is provided between the lower bowl and the lower hose; the sealing gasket ring can increase the sealing performance of the connection point between the hose and the anti-blocking component.
