Description

Technical Field

[0001] The utility model relates to the technical field of waste sand treatment for electric fused bricks, in particular to a device for filtering and recovering waste sand from sand casting. Background Art

[0002] The fused brick sand mold is a mold used for the production of fused bricks. It is usually made of a mixture of silica sand and other materials with a binder. It provides a specific shape and structure for the molding of fused bricks. The fused brick sand mold will gradually wear out and fail during use, thereby generating waste sand. This waste sand mainly comes from the replacement and trimming of the sand mold and defective products in the production process.

[0003] In the prior art, waste sand is mainly recycled through screening and classification to separate reusable waste sand, which is then reused in sand mold making after proper treatment. However, this method easily screens out waste sand with larger particles and mixes it in, which is difficult to distinguish well and requires multiple screenings, which is troublesome. In addition, larger and sticky waste sand with large particles is directly discarded, which causes a waste of resources. Therefore, the technology in this field proposes a sand casting waste sand filtering and recovery device to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a sand casting waste sand filtering and recovery device, which aims to improve the problem that during screening in the prior art, waste sand with larger particles will be mixed with waste sand with smaller particles, making it difficult to distinguish them well, and larger sticky waste sand with large particles will be directly discarded, resulting in a waste of resources.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a device for filtering and recovering waste sand from sand casting, comprising a crushing box, a motor is installed on the outside of the crushing box, two crushing rollers are rotatably connected inside the crushing box, one end of the crushing roller is fixedly connected to a cylindrical gear, the other end of one of the crushing rollers is fixedly connected to a pulley, the bottom of the crushing box is fixedly connected to a recovery box, the inside of the recovery box is rotatably connected to a rotating rod, the outside of the rotating rod is fixedly connected to a cam, the inside of the recovery box is slidably connected to a screening net, two limit blocks are fixedly connected to the outside of the screening net, two limit grooves are provided on the inside of the recovery box, and a discharge assembly is arranged on the outside of the recovery box, and the discharge assembly is used to push out large particles of material remaining after screening inside the recovery box.

[0006] Furthermore, the discharge assembly includes a mounting frame, one end of the mounting frame is fixedly connected to the outside of the recovery box, and the other end of the mounting frame is fixedly connected to a telescopic connecting rod.

[0007] Furthermore, the bottom end of the telescopic connecting rod is fixedly connected to an electric push rod, and the output end of the electric push rod is fixedly connected to a push plate.

[0008] Furthermore, two spring telescopic rods are fixedly connected to the top of the push plate, a mounting bar is fixedly connected to the inner side of the recycling box, and the bottom of the mounting bar is fixedly connected to the tops of the two spring telescopic rods.

[0009] Furthermore, the bottom of the push plate is slidably connected to the top of the screening net, and a discharge port is provided on the outer side of the recovery box.

[0010] Furthermore, the output end of the motor is fixedly connected to one end of one of the crushing rollers, and the outer sides of the two cylindrical gears are meshedly connected.

[0011] Furthermore, a belt is sleeved on the outer periphery of the first pulley and the outer periphery of the second pulley, and the outer side of the cam is in contact with the bottom of the screening net.

[0012] Furthermore, the outer side of the limiting block is slidably connected to the inner side of the limiting groove.

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

[0014] 1. In the utility model, the crushing rollers are driven to rotate by starting the motor. Under the meshing action of the two cylindrical gears, the two crushing rollers will rotate at the same time, and then the waste sand is put into the top of the crushing box for crushing. The larger particles of waste sand that are bonded can be crushed and then recycled to avoid wasting resources. At the same time, under the rotation of the cam, the screening net can also screen the waste sand, realizing the integrated effect of crushing and screening, making the work efficiency higher.

[0015] 2. In the utility model, the elastic force of the two spring telescopic rods can make the bottom of the push plate always fit against the top of the screening net when the screening net is shaken up and down for screening the waste sand. The electric push rod is started to push the push plate to fit against the top of the screening net and move it. The large particles of waste sand on the top of the screening net can be pushed from the discharge port to the outside of the recovery box for discharge, which can prevent the discarded waste sand from remaining in the recovery box for too long and mixing with the waste sand in the subsequent crushing process, resulting in the problem of multiple screenings wasting equipment energy consumption.
