Description

Technical Field

[0001] This utility model relates to the field of ceramic crushing technology, specifically to a waste ceramic recycling and crushing equipment. Background Technology

[0002] Ceramic crushing and recycling is a process of reusing waste ceramic products through physical crushing, screening, and reprocessing. Equipment such as double roll crushers and jaw crushers are used to crush ceramic waste to the target particle size, and then the particles are further ground to the required fineness through high-pressure mills or Raymond mills.

[0003] When using a high-pressure mill for grinding, the ceramic particles are ground at the bottom of the mill casing, and air is supplied from the bottom through a connecting duct, causing the powder to be discharged from the upper suction fan and connecting duct. During this process, the mesh structure of the suction fan casing is used to filter large particles to ensure grinding quality. However, the suction fan itself has a certain suction force, and particles are easily adsorbed on its surface, causing some blockage in the filter pores and thus making it impossible to maintain efficient powder delivery. Therefore, it is necessary to design a pre-filter structure that is easy to clean to solve the shortcomings of the high-pressure mill. Utility Model Content

[0004] The purpose of this utility model is to provide a waste ceramic recycling and crushing equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a grinding mill housing, an air inlet pipe fixed to the bottom periphery of the grinding mill housing, a suction fan installed on the top of the grinding mill housing with a connecting air duct fixed to its upper end, a grinding ring and grinding roller installed at the bottom of the grinding mill housing, a connecting channel provided in the middle of the grinding mill housing, a feed inlet fixed to the side wall of the grinding mill housing, a sliding plate slidably connected inside and through the grinding mill housing, a pair of through holes on the sliding plate, a filter screen fixed inside each through hole, one through hole aligned with the connecting channel, and cleaning mechanisms provided on both sides of the grinding mill housing corresponding to the sliding plate.

[0006] Preferably, a synchronous motor is fixed on the outer side of the mill housing and at a position corresponding to the sliding plate. A drive groove is provided on the side wall of the sliding plate, and a linear toothed plate is fixed in the drive groove. The output end of the synchronous motor is located in the drive groove and is equipped with a drive gear that meshes with the linear toothed plate.

[0007] Preferably, an airtight pad is fixed to the outer surface of the sliding plate.

[0008] Preferably, the cleaning mechanism includes a side frame, which is fixed to both sides of the mill housing and aligned with the sliding plate. An air pump is fixed to the top of the side frame, and a serpentine air pipe is fixed to the output end of the air pump. The serpentine air pipe is fixed to the inner wall of the upper end of the side frame and is vertically aligned with the perforation. Nozzles are uniformly fixed to the bottom of the serpentine air pipe.

[0009] Preferably, the side frame is a funnel-shaped structure, and its bottom is fixed to the side wall of the mill housing. An opening structure is provided at the connection between the side frame and the side wall of the mill housing.

[0010] Preferably, a support plate is fixed inside the side frame, and the support plate is located below the sliding plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting a filter screen inside the grinding mill shell, particles can be prevented from being adsorbed into the filter holes of the air suction machine shell and causing blockage during air suction.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3This utility model provides a technical solution: it includes a grinding mill shell 1, an air inlet pipe 13 fixed to the bottom periphery of the grinding mill shell 1, a fan 11 installed on the top of the grinding mill shell 1, and a connecting air duct 12 fixed to the upper end of the fan 11, a grinding ring and a grinding roller installed at the bottom of the grinding mill shell 1, a connecting channel 2 provided in the middle of the grinding mill shell 1, a feed inlet 14 fixed to the side wall of the grinding mill shell 1, a sliding plate 3 slidably connected inside the grinding mill shell 1 and passing through the grinding mill shell 1, a pair of through holes 31 opened on the sliding plate 3, a filter screen 32 fixed in the through holes 31, one of the through holes 31 being aligned with the connecting channel 2, and cleaning mechanisms provided on both sides of the grinding mill shell 1 at positions corresponding to the sliding plate 3.

[0016] A synchronous motor 5 is fixed on the outer side of the mill housing 1 and at a position corresponding to the sliding plate 3. A drive groove 33 is opened on the side wall of the sliding plate 3. A linear toothed plate 34 is fixed in the drive groove 33. The output end of the synchronous motor 5 is located in the drive groove 33 and is equipped with a drive gear that meshes with the linear toothed plate 34. An airtight gasket is fixed on the outer surface of the sliding plate 3.

[0017] The cleaning mechanism includes a side frame 4, which is fixed to both sides of the mill housing 1 and aligned with the sliding plate 3. An air pump 43 is fixed to the top of the side frame 4, and a serpentine air pipe 41 is fixed to the output end of the air pump 43. The serpentine air pipe 41 is fixed to the upper inner wall of the side frame 4 and is vertically aligned with the perforation 31. Nozzles 42 are evenly fixed to the bottom of the serpentine air pipe 41. The side frame 4 has a funnel-shaped structure and its bottom is fixed to the side wall of the mill housing 1. An opening structure is provided at the connection between the side frame 4 and the side wall of the mill housing 1. A support plate 44 is fixed inside the side frame 4 and is located below the sliding plate 3.

[0018] Working principle: First, connect the entire device to an external power source. Then, feed the pre-crushed ceramic particles into the mill housing 1 through the feed inlet 14. The internal grinding ring and grinding roller work together to grind the particles into powder. Air is supplied through the air inlet pipe 13 and drawn in by the suction fan 11, blowing the powder upwards and discharging it through the connecting air duct 12. This is the existing technology. During the process, the powder material passes through the connecting channel 2, where pre-filtration using the filter screen 32 prevents particles from adsorbing onto the surface of the suction fan 11, thus reducing clogging. The filter screen 32 is clogged. The sliding plate 3 can be used to slide the clogged filter screen 32 into the corresponding side frame 4 for cleaning. At the same time, another filter screen 32 will replace the filter, achieving the purpose of automatic cleaning. In this process, the output end of the synchronous motor 5 drives the drive gear to rotate, and the linear gear plate 34 drives the sliding plate 3 to slide. After the clogged filter screen 32 is located below the nozzle 42, the air pump 43 supplies air, which can spray high-speed airflow to clean the filter screen 32, avoiding the trouble of manual cleaning.
