Description

Technical Field

[0001] The utility model belongs to the technical field of impurity removal equipment, and specifically relates to a spiral sand making machine. Background Art

[0002] The urban solid waste recycling system in the prior art mainly includes four links: solid waste collection, classification, treatment and reuse. In the solid waste collection link, urban solid waste is collected uniformly by setting up fixed and mobile collection points. In the classification link, solid waste is divided into several categories such as recyclables, hazardous waste, kitchen waste and other waste by using equipment such as robotic arms and conveyor belts combined with manual operations. In the treatment link, different treatment methods are used for different types of solid waste, such as reprocessing recyclables for reuse, harmless treatment of hazardous waste, and biodegradation of kitchen waste. In the reuse link, the treated solid waste is converted into resources, such as heat energy, electricity, fertilizer, etc., to achieve the recycling of solid waste.

[0003] Among them, for woven bags, PE materials, hard plastic and other materials in construction solid waste, after they are separated from the construction solid waste, impurities such as sand and gravel aggregates are generally left on them. If they are not removed, the subsequent use of these materials will be affected; in the prior art, the patent with patent number CN 109501054 A provides a waste plastic sand remover, which first crushes the plastic and then separates the plastic from sand and gravel through high-pressure airflow, but the sand removal by this method requires the material to be crushed first, so only one material can be sanded at a time, otherwise it is difficult to separate the materials after sand removal, so the sand removal efficiency is low. Utility Model Content

[0004] Aiming at the problem that the sand removing device in the prior art can only remove sand from one type of material at a time, the utility model provides a spiral sand making machine.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A spiral sand making machine comprises a frame, wherein a sand making box with openings at the top and the bottom is arranged on the frame, a sand making box is detachably connected to the top of the sand making box with a sand making machine cover, a screen is arranged at the bottom of the sand making box, the screen and the sand making machine cover together form a screening chamber, a transmission main shaft is rotatably connected in the cylindrical screening chamber, the transmission main shaft is connected to a driving device, a sand making blade and a spiral blade are arranged on the transmission main shaft, a feed port is arranged on the sand making machine cover at a position corresponding to the spiral blade, and a discharge port is arranged on the side wall of the sand making box away from the spiral blade.

[0007] After adopting this technical solution, when in use, the material is put into the screening chamber from the feed port, and then falls onto the spiral blades. The spiral blades rotate to transport the material to the sand-beating blades until the material reaches the sand-beating blades. The sand-beating blades rotate to beat the material, causing the sand and gravel on the material to fall off and fall out of the screen. The spiral blades continuously transport the material forward, driving the material in front to move toward the discharge port until the material reaches the discharge port. The material is discharged under the thrust generated by the rotation of the sand-beating blades, thereby achieving sand removal. Sand removal by this device can remove sand from multiple materials at the same time, and the materials can be sorted after sand removal, which reduces the difficulty of sorting and avoids sand and gravel falling and polluting the environment during material sorting.

[0008] Preferably, a plurality of observation windows are respectively provided on both sides of the sand maker cover, and a transparent cover is provided at each observation window, one end of the transparent cover is hinged to the sand maker cover, and the other end is detachably connected to the sand maker cover.

When a minor fault occurs (such as material jamming), the transparent cover can be opened and the material can be processed through the observation window.

[0010] Preferably, both sides of the rack are provided with a walking rack.

[0011] After adopting this technical solution, people can walk to the observation window for observation via the walkway.

[0012] Preferably, the screening chamber is a cylindrical structure, the sand-beating blades include an upper blade and a lower blade of the same size, the upper blade and the lower blade are both rectangular structures, the upper blade and the lower blade are respectively connected to the upper surface and the lower surface of the transmission main shaft, and the upper blade and the lower blade are located on the same horizontal plane.

[0013] After adopting this technical solution, the shape of the screening chamber matches the movement path of the sand-beating blades, so that the material can be fully contacted with the sand-beating blades, and the material can be fully beaten.

[0014] Preferably, the length of the area on the transmission main shaft where the sand blasting blades are installed is greater than the length of the area where the spiral blades are installed.

[0015] Preferably, a cover body with side openings is also provided at the feed inlet of the sand maker cover.

[0016] After adopting this technical solution, the feed inlet is shielded by a cover with a side opening to prevent sand and gravel from being thrown out during the sand removal process.

[0017] Preferably, a screen and an extension plate are provided at the bottom opening of the sand box, the extension plate is provided at the discharge port, and one side of the screen is in contact with one side of the extension plate.

[0018] After adopting this technical solution, no screen is set near the feed port, but an extension plate that cooperates with the discharge port is set to ensure that the material is discharged smoothly from the discharge port.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0020] 1. When the utility model is used, the material is put into the screening chamber from the feed port, and then falls onto the spiral blades. The spiral blades rotate to transport the material to the sand-beating blades until the material reaches the sand-beating blades. The sand-beating blades rotate to beat the material, causing the sand and gravel on the material to fall off and fall out of the screen. The spiral blades continuously transport the material forward, driving the material in front to move toward the discharge port until the material reaches the discharge port. The material is discharged under the thrust generated by the rotation of the sand-beating blades, thereby achieving sand removal. Sand removal by this device can remove sand from multiple materials at the same time, and the materials can be sorted after sand removal, which reduces the difficulty of sorting and avoids sand and gravel falling and polluting the environment during material sorting.
