Description

Technical Field

[0001] The present invention relates to the technical field of ore pigments, and particularly to a mechanical ore pigment grinding machine with a screening function. Background Technique

[0002] Mineral pigments are inorganic pigments, a type of inorganic substances, belonging to inorganic colored pigments. Their sources mainly have two categories: one is made from natural ores through ore dressing, crushing, grinding, grading, and refining, and is mainly used for painting, handicrafts, antique imitation, cultural relic restoration, etc. Another source of inorganic pigments is chemical synthetic pigments made from natural mineral products through a series of chemical treatment processes.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] First, in the present invention, grinding is carried out through a grinding bin. The ground raw materials fall onto a placing table through a first discharge pipe and are pushed into a collecting hopper by a first push plate through a cylinder. The grinding bin is fixed on a bottom plate through a first support plate, and a one-way open space is formed between a first limiting plate between two first support plates, the first push plate, and the placing table. When too much raw material needs to be discharged at one time, the cylinder can be closed to allow the raw materials to accumulate in this one-way open space and fall naturally into the collecting hopper. Then, the remaining raw materials that have not fallen naturally are pushed in by the pushing of the cylinder. The raw materials are transported into a screening bin through a vertical feeder and screened through a fine sieve. The raw materials with a small particle size fall to the bottom of the screening bin, and the raw materials with a particle size not small enough are finely ground through a grinder arranged inside the screening bin until their particle size is small enough to fall to the bottom. Raw materials with different particle sizes are separated through screening, and then the raw materials are subjected to secondary grinding through a separately arranged grinder. There is no need to grind the whole raw materials again, only a part of the raw materials needs to be ground separately, which is more efficient and lower in cost, and solves the problem that larger raw material particles cannot be directly processed in the next step.

[0018] Second, in the present invention, the incoming raw materials are roughly screened through a coarse sieve, and the raw materials that are difficult to break by the grinder are screened outside the screening bin in advance to prevent them from jamming the grinder and reducing its efficiency. The second push plate is used to push these raw materials with too high a particle size outward through an electric push rod. The raw materials fall from the same angle through an inclined plate through the limitation of a limiting angle and a mounting plate and are placed inside a collecting box for processing. The second limiting plate prevents the raw materials from falling onto the bottom plate due to a large thrust. The discharge hopper can accumulate the raw materials piled up inside the screening bin, and the screening bin is indirectly supported in the air through the connection and support of a support rod and the discharge hopper.

[0019] Third, in the present invention, it is moved through self-locking universal wheels. When fixation is required, the first electric telescopic rod is retracted, and the second electric telescopic rod extends downward to support the bottom plate through a cushion plate. This design enables the whole device to move within a certain area, so that it can take raw materials at a storage location for grinding and then move to a processing location. The ground and screened materials in the second discharge pipe are transported through a transfer pipe. A blower can generate an air flow to drive the materials to move in the transfer pipe, and an electric valve can prevent the materials from falling out of the transfer pipe during movement or at non-discharging locations, resulting in premature leakage.

[0032] The screening mechanism 1 includes a bottom plate 101. A grinding bin 102 is arranged at the top of the bottom plate 101. A screening bin 103 is arranged at the top of the bottom plate 101. A fine screen 114 is fixedly connected inside the screening bin 103. A first discharge pipe 104 is fixedly connected to the bottom of the grinding bin 102.

When fixation is required, the first electric telescopic rods 301 are retracted, and the second electric telescopic rods 303 extend downward. The bottom plate 101 is supported by the backing plates 304. This design enables the whole device to move within an area, enabling it to take raw materials at the material storage place for grinding, and then move to the processing place. The screened and ground materials in the second discharge pipe 305 are transported through the transfer pipe 306. Among them, the blower 307 can make the materials drive in the transfer pipe 306 through the air flow generated by blowing.

The raw materials with different particle sizes are separated by screening, and the raw materials are subjected to secondary grinding through the separately provided grinder 113. There is no need to grind the whole raw materials again, only some of the raw materials need to be ground separately, which is more efficient and lower in cost, and solves the problem that larger raw material particles cannot be directly processed in the next step. The falling raw materials are roughly screened by the coarse screen 211, and the raw materials that are difficult to be broken by the grinder 113 are screened outside the screening chamber 103 in advance to prevent them from jamming the grinder 113 and reducing its efficiency. The raw materials with too high particle sizes are pushed outward by the second push plate 204 using the electric push rod 203. The raw materials fall from the same angle through the inclined plate 206 due to the limitation of the limiting angle 205 and the mounting plate 201 and are placed inside the collection box 208 for processing. The second limiting plate 207 prevents the raw materials from falling onto the bottom plate 101 due to too large a thrust.

When fixation is required, the first electric telescopic rod 301 is retracted, and the second electric telescopic rod 303 extends downward to support the bottom plate 101 through the cushion plate 304. This design enables the whole device to move within an area, enabling it to take raw materials at the storage location for grinding and then move to the processing location, and the screened and ground materials in the second discharge pipe 305 are transported through the transmission pipe 306. The air blower 307 can make the materials be transmitted in the transmission pipe 306 through the air flow generated by blowing, and the electric brake 308 can prevent the materials from falling out of the transmission pipe 306 during movement or at non-discharge locations, resulting in premature leakage.
