Description

Technical Field

[0001] The present application relates to the technical field of waste gas recycling, and in particular to a waste gas recycling system for a floating sand barrel. Background Art

[0002] Investment casting, also known as lost wax casting or precision casting, is an advanced process designed for the production of metal castings with complex shapes, high precision and high surface finish. The process begins with the careful production of a wax pattern, which is an accurate prototype of the final casting, and its shape and details are crucial. Subsequently, this prototype undergoes multiple delicate processes, among which the key steps include slurry application (also known as slurry coating, coating) and sandblasting with a floating sand bucket (also known as sanding, sand casting) to build a solid and breathable shell to prepare for subsequent metal pouring.

[0003] In the existing floating sand bucket technology, its core components usually include a barrel body, a high-efficiency sandblasting device installed on the side of the barrel body, and a blower as a power source. The latter is often fixed at the bottom of the barrel body to drive the sand to spray evenly on the surface of the wax model. In addition, the top of the barrel is cleverly designed with a dust removal port to promptly remove the dust and exhaust gas generated during the sandblasting process to ensure the cleanliness of the operating environment and the health of the workers. The dust removal port is generally connected to professional dust removal equipment to achieve preliminary purification of exhaust gas and effective collection of dust.

[0004] However, it is worth noting that although the current system can effectively treat and purify the exhaust gas, these purified gases are often directly discharged into the external environment and fail to be further effectively utilized. This not only causes a significant waste of energy, but also virtually increases the overall operating cost of the investment casting process. Obviously, there is significant room for optimization. Utility Model Content

[0005] The purpose of the present application is to provide an exhaust gas circulation system for a floating sand barrel, so as to solve the problem that the exhaust gas cannot be effectively utilized in the above-mentioned related technologies.

[0006] The waste gas circulation system for a floating sand barrel provided in the present application adopts the following technical solution:

[0008] By adopting the above technical solution, due to the connection setting of the recovery pipe and the circulation pipe, the waste gas generated during the floating sand bucket process is recovered into the dust removal component through the recovery pipe, and after the dust removal component purifies the waste gas, the waste gas is re-injected into the blower through the circulation pipe, so as to realize the recycling of the waste gas, improve the utilization efficiency of energy, and reduce the overall production cost.

[0017] Optionally, a discharge port is opened at the lower part of the vertical outer side surface of the barrel body, and a sealing plate for blocking the discharge port is further arranged outside the barrel body.

[0018] By adopting the above technical solution, due to the cooperative setting of the discharge port and the sealing plate, when it is necessary to overhaul the barrel body, the staff can open the sealing plate, which is convenient for discharging the original sand in the barrel from the discharge port, improving the corresponding overhaul efficiency.
