According to the device, raw materials for producing a solid reagent can be ground differently twice, so that the raw materials for producing the solid reagent can be ground more sufficiently, and a situation that the raw materials for producing the solid reagent are not ground sufficiently can be avoided.

The invention belongs to the technical field of medical treatment, and particularly relates to a powder medicament manufacturing method for the pharmacy department. The powder medicament manufacturingmethod adopts grinding equipment. The grinding equipment comprises a grinding barrel, a connecting frame, a push handle and a conveying unit. The grinding barrel is in a cover-less cylinder shape. The connecting frame is vertically connected into the barrel wall of the grinding barrel. A grinding protrusion and a spiral groove are formed in the inner side barrel wall of the grinding barrel. The push handle is arranged on the right side of the exterior of the grinding barrel. The conveying unit is used for conveying tablets to the left side of the interior of the grinding barrel for grinding,the tablets are placed into the grinding barrel from a feeding hole, and then tablet raw materials are pushed to the left side of the grinding barrel through the push handle and the conveying unit. The tablet raw materials are fully crushed and ground through the grinding protrusion on the left side inner wall of the grinding barrel. Powder formed after grinding flows out from the left end of thegrinding barrel. The grinding equipment adopted by a grinding method is simple in structure and low in cost, the tablets are fully extruded and ground through the grinding protrusion and a pushing block of a material passing hole in the grinding barrel, the operation steps are simple, and the grinding efficiency is improved greatly.

The present invention relates to the technical field of soya-bean milk machine, in particular to a new type of grinding device, comprising a motor, a moving grinding wheel and a static grinding wheel capable of relative rotation, the moving grinding wheel is connected to the motor through a drive shaft passing through its center, and the connection between the moving grinding wheel and the static grinding wheel There is a rotation gap between them, and the movable grinding wheel is slidingly connected with the drive shaft. At least the lower part of the connection between the drive shaft and the movable grinding wheel is a matching structure of a tapered column and a tapered hole gradually widening from top to bottom. The invention effectively prevents the material from being stuck and enables the material to be fully ground through the special design of the tapered drive shaft.

The invention belongs to the technical field of medical and nursing instruments, and particularly relates to a pharmaceutical crushing device for a pharmacy department. The pharmaceutical crushing device for the pharmacy department comprises a grinding cylinder, a connecting rack, a pushing hand and a feeding unit. The grinding cylinder is a cylinder without a cover, and the central axis of the grinding cylinder is placed horizontally. The connecting rack is vertically connected into the wall of the grinding cylinder, a grinding protrusion and a spiral groove are formed in the wall of the inner side of the grinding cylinder, and the grinding protrusion is used for extruding and grinding tablets. A feeding hole is formed vertically in the wall of the grinding cylinder, and the feeding holeis located in the middle of the grinding protrusion and the spiral groove, and the feeding hole is used for adding the tablet material into the grinding cylinder. The pushing hand is arranged on the right side of the outer portion of the grinding cylinder, and is used for placing the tablets into the grinding cylinder. The feeding unit is arranged in the grinding cylinder, and the feeding unit isused for sending the tablets to the left side of the inner portion of the grinding cylinder for grinding. According to the pharmaceutical crushing device for the pharmacy department, through mutual matching of the grinding protrusion in the grinding cylinder and a pushing block, the tablets entering into the grinding cylinder is fully rolled, the grinding cost is low, and the operation is easy.

The invention discloses a small amount of metal tissue grinding device, which comprises a metal block and a metal grinding wheel. The metal block is provided with a plurality of grinding grooves; the metal grinding wheel is provided with a handle, and the lower end of the handle is divided into two separate metal grinding wheels. The branches on both sides of the wheel, the ends of the branches are connected by a cross bar passing through the center of the metal grinding wheel, the metal grinding wheel rotates with the cross bar as the axis, and one end of the grinding groove extends to the side of the metal block and forms a discharge port. Based on the premise that liquid nitrogen instantly solidifies a small amount of animal and plant tissue samples at ultra-low temperature, the solid samples are repeatedly rolled by using the hardness of metal blocks and metal grinding wheels that are difficult to deform, so as to solve the problem of tissue samples in the grinder grinding method or porcelain mortar grinding method. Insufficient grinding, especially the hard or flexible tissue samples are difficult to achieve the ideal degree of grinding under normal temperature conditions of the grinder, and the porcelain mortar is easy to remain in the grinding process.

The invention discloses an accurate rice grinding device for rice noodle processing. The accurate rice grinding device for rice noodle processing comprises a box body, a storage box is arranged at theleft side of the bottom end inside the box body, a filter net is arranged inside the storage box, a fixing block is arranged in the middle of the right side inside the box body, a grinding box is arranged at the left end of the fixing block, a discharging pipe is arranged at the lower end of the grinding box, a fixing frame is arranged at the upper portion of the right side inside the box body, amotor rack is arranged at the left portion of the rear side of the fixing frame, a motor is arranged at the upper end of the motor rack, and a motor shaft is arranged at the front end of the motor. When the device works, a box cover is opened, steel teeth on a rotating gear preliminarily process rice, and the phenomenon that grinding is not sufficient during follow-up processing is avoided. An adjusting plate swings around a rotating shaft, a first thin rod and a second thin rod drive grinding plates to reciprocate, arc protrusions on the grinding plates sufficiently grind rice, and the grinding efficiency can be improved due to reciprocating motion of the two grinding plates.
