Description

Technical Field

[0001] This utility model relates to the field of premixed mortar processing technology, and in particular to a premixed mortar sand screening device. Background Technology

[0002] Premixed mortar refers to various mortar mixtures produced by specialized manufacturers and used in construction projects. It is a new type of building material that has been developed in my country in recent years. According to its performance, it can be divided into ordinary premixed mortar and special mortar. When producing premixed mortar, it is necessary to strictly control the coarseness of the sand and gravel in order to control the production quality of premixed mortar.

[0003] Problems compared to existing technologies: Existing premixed mortar sand screening devices generally use inclined vibrating screens to screen sand. First, sand tends to clump together during the feeding stage, and the sand at the top cannot quickly contact the vibrating screen, resulting in uneven and slow screening, which reduces the efficiency and quality of the screening operation. Second, existing premixed mortar sand screening devices generate a lot of dust during the feeding and discharging stages, which pollutes the workshop environment and is harmful to workers' health. Therefore, we propose a premixed mortar sand screening device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a premixed mortar sand screening device.

[0005] The present invention solves its technical problem through the following technical solution: It includes a mounting base, a screening mechanism on the top of the mounting base, the screening mechanism including an elastic support member, the elastic support member being fixed to the top of the mounting base by bolts, a mounting housing fixed to the top of the elastic support member, a feed hopper fixed to the top of the mounting housing, a screen plate fixed to the inner wall of the mounting housing, a vibrator fixed to the outer side of the mounting housing by bolts, a discharge hopper fixed to the bottom of the mounting housing, a guiding mechanism inside the mounting housing, an adsorption mechanism on the inner wall of the mounting base, and a driving mechanism on the top of the adsorption mechanism.

[0006] As a further improvement of this utility model, a control panel is provided on one side of the mounting base.

A collection box is fixed to the top of the support rod by bolts, and a cover plate is fixed to the top of the collection box by bolts. An adsorption tube A is fixed to one side of the collection box and is connected to the feed hopper. An adsorption tube B is fixed to the side wall of the collection box and is connected to the discharge hopper.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figure 1-6This utility model provides a technical solution: It includes a mounting base 100, a control panel 110 on one side of the mounting base 100, and a screening mechanism on the top of the mounting base 100. The screening mechanism includes an elastic support member 210, a mounting housing 220, a feed hopper 221, and a screen plate 230. A discharge trough 240 is fixed to one end of the elastic support member 210. A vibrator 250 is bolted to the outside of the mounting housing 220. A discharge hopper 260 is fixed to the bottom of the mounting housing 220. A guiding mechanism is provided inside the mounting housing 220. An adsorption mechanism is provided on the inner wall of the mounting base 100, and a driving mechanism is provided at the top of the adsorption mechanism. Through the screening mechanism and the feed hopper 221... 1. Sand is injected into the mounting housing 220. The vibrator 250 drives the mounting housing 220 to vibrate, which in turn drives the screen plate 230 to vibrate. The sand is screened through the inclined screen plate 230. During the screening operation, the material guiding mechanism pushes the sand to even out any sand that has piled up during loading. The sand is guided evenly downwards, ensuring that it can contact the screen plate 230 uniformly, which improves the efficiency of the screening operation and ensures the quality of the sand screening. During the screening operation, the adsorption mechanism and the drive mechanism work together to adsorb and treat the dust generated during loading and unloading, preventing dust from drifting into the workshop, preventing pollution of the workshop's air quality, and preventing harm to the workers' health, thus improving the environmental friendliness of the device.

[0026] Specifically, the material guiding mechanism includes a drive motor 310, which is fixed to the side wall of the mounting housing 220 by bolts. The output end of the drive motor 310 is provided with a drive shaft 320, and an installation roller 330 is fixed to the outside of the drive shaft 320. Multiple material-pushing plates 340 are fixed to the outside of the installation roller 330. By providing the material guiding mechanism, during the screening operation, the drive motor 310 drives the drive shaft 320 to rotate, which in turn drives the multiple material-pushing plates 340 to push the sand material. This can evenly distribute the sand material that is piled up during feeding, guide the sand material evenly downwards, and ensure that the sand material can evenly contact the screen plate 230, thereby improving the efficiency of the screening operation and ensuring the quality of sand screening.

[0027] Specifically, the adsorption mechanism includes a support rod 410, which is bolted to the inner wall of the mounting base 100. A collection box 420 is bolted to the top of the support rod 410, and a cover plate 430 is bolted to the top of the collection box 420. An adsorption tube A440 is fixed to one side of the collection box 420 and connected to the feed hopper 221. An adsorption tube B450 is fixed to the side wall of the collection box 420 and connected to the discharge hopper 260. By setting up the adsorption mechanism, during the screening operation, the gas inside the collection box 420 is extracted by the driving mechanism to create a negative pressure, which in turn causes the adsorption tubes A440 and B450 to generate suction. This allows the dust generated during the loading and unloading operations to be adsorbed and treated. Finally, the adsorbed dust is collected by the collection box 420, preventing dust from drifting into the workshop, thus preventing pollution of the workshop's air quality and preventing harm to workers, thereby improving the environmental friendliness of the device.

[0028] Specifically, the driving mechanism includes a filter box 510, which is fixed to the top of the cover plate 430 by bolts. A suction fan mounting base 520 is fixed to the top of the filter box 510, and a suction fan 530 is fixed to the top of the suction fan mounting base 520. An air suction pipe 540 is fixed to the bottom of the suction fan 530 and is connected to the filter box 510. With the driving mechanism, during the adsorption operation, the suction fan 530 is started, and the suction fan 530 performs air suction operation on the filter box 510 through the air suction pipe 540. The air inside the collection box 420 is filtered and adsorbed through the filter box 510, creating a negative pressure in the collection box 420, which can start the driving action of the adsorption operation.

[0029] Working Principle: During use, the device is controlled via the control panel 110. Sand is injected into the mounting housing 220 through the feed hopper 221. The vibrator 250 drives the mounting housing 220 to vibrate, which in turn drives the screen plate 230 to vibrate. The inclined screen plate 230 screens the sand. Small sand particles are discharged through the discharge hopper 260, while large sand particles are guided through the discharge chute 240 and discharged from the device. This achieves the vibration screening operation of the sand. During the screening operation, the drive motor 310 drives the drive shaft 320 to rotate, which in turn drives the mounting roller 330 to rotate. The rotation of the 0-axis drives multiple material feeding plates 340 to feed the sand, which can evenly distribute the sand that is piled up during feeding, and guide the sand downwards evenly to ensure that the sand can evenly contact the screen plate 230. During the screening operation, the suction fan 530 is started. The suction fan 530 sucks air from the filter box 510 through the suction pipe 540. The filter box 510 filters and adsorbs the air inside the collection box 420, creating a negative pressure in the collection box 420. This causes the adsorption pipes A440 and B450 to generate suction, which can adsorb and treat the dust generated during the feeding and unloading operation. Finally, the adsorbed dust is collected through the collection box 420.

Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and accompanying drawings.
