Description

Technical Field

[0001] The present application relates to the field of regeneration furnace technology, and in particular to a coated sand boiling regeneration furnace. Background Art

[0002] Coated sand mainly uses high-quality selected natural quartz sand as raw sand, thermoplastic phenolic resin, hexamethylenetetramine and reinforcing agent as raw materials. According to the different technical requirements of users, the proportion is appropriately adjusted in terms of curing speed, demolding, fluidity, disintegration, casting surface finish and storage. It is one of the best modeling materials for automobiles, tractors, hydraulic parts, etc. Coated sand mold cavity cannot be used for a second time after use. In order to reduce the waste of coated sand, the used coated sand needs to be recycled. The recycling process mainly includes three processes: preheating treatment of old sand, thermal roasting and post-treatment of regenerated sand. A large amount of waste gas will be generated during the thermal roasting process. The existing boiling regeneration furnace is equipped with a waste gas filtration mechanism to treat the waste and then discharge it, reducing the impact of waste gas on the environment.

[0003] The prior art CN212778618U discloses a coated sand boiling regeneration furnace, which filters the exhaust gas through a filter screen, and then uses a motor to drive a brush to clean the filter screen surface, so that the filter screen can maintain a high filtering efficiency. However, the particulate impurities brushed off by the brush will also be brought to the filter screen by the airflow, and the cleaning effect is not ideal. In addition, the particulate impurities brushed off are accumulated inside the pipe, making the discharge process of the particulate impurities more complicated.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the existing exhaust gas filtering mechanisms have the problems of poor cleaning effect and complicated discharge process of particulate impurities, which reduces the cleaning effect and cleaning efficiency of the exhaust gas filtering mechanisms. Utility Model Content

[0005] In order to solve the problems of poor cleaning effect and complicated discharge process of particulate impurities in existing exhaust gas filtering mechanisms, the present application provides a coated sand boiling regeneration furnace.

[0006] The present application provides a coated sand boiling regeneration furnace, which adopts the following technical solution:

[0007] A coated sand boiling regeneration furnace, comprising a regeneration furnace body, an air suction pump, a filter box arranged on the regeneration furnace body, a filtering mechanism, a cleaning mechanism and a collecting mechanism arranged in the filter box; the air inlet end of the air suction pump is connected to the regeneration furnace body, and the air outlet end of the air suction pump is connected to the filter box, the filtering mechanism comprises a first filter screen, a second filter screen and an activated carbon filter element arranged between the first filter screen and the second filter screen arranged in the filter box, an air outlet is provided on the side of the filter box away from the regeneration furnace body, the cleaning mechanism comprises a cleaning brush slidably connected to the side wall of the filter box and a driving assembly connected to the cleaning brush, the cleaning brush abuts against the first filter screen, the collecting mechanism comprises a collecting hood, a hose and a collecting box sleeved on the outside of the cleaning brush, one end of the hose is connected to the collecting hood, and the other end is connected to the collecting box, and a cleaning door is provided on the collecting box.

[0008] By adopting the above technical solution, the suction pump transports the flue gas generated by the regeneration furnace body to the filter box, and the flue gas is filtered through the first filter, the activated carbon filter element and the second filter, and then the flue gas is discharged from the filter box through the air outlet. The driving component drives the cleaning brush to clean the first filter, and the cleaned particulate impurities fall into the collection cover, and then enter the collection box through the hose. The cleaning door can be opened to clean the particulate impurities in the collection box, and the cleaning process is simple and convenient. The above structure reduces the phenomenon that the particulate impurities are driven by the flue gas to be adsorbed on the first filter again, thereby improving the cleaning effect and cleaning efficiency of the filter mechanism.

[0010] By adopting the above technical solution, the first transmission motor drives the reciprocating screw to rotate, the reciprocating screw drives the first slider to slide in the installation slot, and the first slider drives the cleaning brush to move back and forth, thereby cleaning the first filter.

[0012] By adopting the above technical solution, when the cleaning brush is cleaning the first filter, the second slider slides in the limiting slide groove. The setting of the limiting slide groove increases the movement stability of the cleaning brush and improves the tightness of the abutment between the cleaning brush and the first filter, thereby improving the cleaning effect of the cleaning brush on the first filter.

[0013] Optionally, the side panels of the collecting cover on both sides away from the cleaning brush are inclined.

[0014] By adopting the above technical solution, the two sides of the collecting cover are inclined to facilitate the particle impurities to fall into the collecting cover, thereby improving the collection effect of the particle impurities.

[0015] Optionally, an adjustment hole is opened on the side wall of the collecting cover close to the first sliding block, and the cleaning brush passes through the adjustment hole and is slidably connected to the adjustment hole.

[0016] By adopting the above technical solution, when the collecting cover abuts against the side wall of the filter box, the cleaning brush has not reached the edge of the first filter screen. At this time, the cleaning brush moves in the adjustment hole toward the side wall of the collecting box, so that the cleaning brush cleans the edge of the first filter screen, thereby improving the cleaning effect of the cleaning brush on the first filter screen.

[0017] Optionally, a spring is provided in the adjustment hole, one end of the spring is connected to the cleaning brush, and the other end is connected to the collecting cover. There are two springs, and the two springs are symmetrically arranged on both sides of the cleaning brush.

[0018] By adopting the above technical solution, when the cleaning brush and the collecting cover leave the side wall of the filter box, the spring makes the cleaning brush located in the middle of the adjustment hole, so that the particle impurities can fall into the collecting cover, thereby improving the collection effect of the particle impurities.

[0019] Optionally, an anti-blocking mechanism is provided in the filter box, and the anti-blocking mechanism includes a mounting plate arranged on the side wall of the filter box, a rocker arranged on the mounting plate, and a transmission assembly, wherein the rocker is rotatably connected to the mounting plate and connected to the transmission assembly.

[0020] By adopting the above technical solution, the transmission assembly drives the rocker to swing back and forth, so that the rocker drives the hose to shake, thereby reducing the phenomenon of particle impurities clogging in the hose and improving the cleaning efficiency of the filter mechanism.

[0021] Optionally, the transmission assembly includes a second transmission motor connected to the mounting plate, a transmission shaft of the second transmission motor is fixedly connected to a crank, an end of the crank away from the second transmission motor is rotatably connected to a connecting rod, and an end of the connecting rod away from the crank is rotatably connected to the rocker.

[0022] By adopting the above technical solution, the second transmission motor drives the crank to rotate, and the crank drives the rocker to swing through the connecting rod. The rocker hits the hose, causing the hose to shake, thereby reducing the phenomenon of granular impurities clogging the hose.

[0023] In summary, this application has the following beneficial technical effects:

[0024] 1. The setting of the collection mechanism allows the falling particulate impurities to be collected, reducing the phenomenon that the particulate impurities are brought back to the filter mechanism by the flue gas, thereby improving the cleaning effect of the filter mechanism;

[0025] 2. The adjustment hole in the collecting tank and the spring in the adjustment hole increase the possibility of the particle impurities falling into the collecting cover, thereby improving the collection effect of the particle impurities;
