The invention discloses a traditional Chinese medicinal material grinding device for quantitatively conveying materials. Four support columns are symmetrically and fixedly connected to the outer wall of the grinding cylinder, and a support plate is fixedly connected to the inner wall of the hopper. The invention can quantitatively send medicinal materials from the hopper into the grinding cylinder for grinding in batches. Since the medicinal materials are pre-chopped into small pieces, the error of quantitative feeding is significantly reduced, and it is helpful for the subsequent grinding process. It significantly improves the working efficiency of the grinding process, and at the same time avoids the clogging caused by the oversized medicinal materials during the transportation and grinding process. This quantitative, batch-by-batch grinding process can effectively solve the problem of fine grinding It takes a long time and the blockage problem is caused by a large amount of material accumulation in the grinding cylinder.

The invention relates to a high-strength, high-thermal-conductivity and modified polyphenyl ether material and a preparation method thereof. The polyphenyl ether material is formed by mixing an enhanced modified material and a thermal conductive modified material; the enhanced modified material is prepared from, by weight, 30-50 parts of polyphenyl ether, 5-15 parts of polystyrene, 40-60 parts of glass fibers, 0.3-0.6 part of lubricant and 0.2-0.5 part of antioxidant; the heat-conducting modified material is prepared from, by weight, 12-40 parts of polyphenyl ether, 10-25 parts of polystyrene, 3-8 parts of toughening agent, 40-70 parts of thermal conductive filler, 1-3 parts of lubricant and 0.2-0.5 part of antioxidant. The polyphenyl ether material is prepared by firstly preparing the enhanced modified material and the thermal conductive modified material respectively and then mixing the enhanced modified material and the thermal conductive modified material in batch according to a certain proportion. Compared with the prior art, the polyphenyl ether material has the advantages of being large in mechanical strength, excellent in thermal conductivity, good in processability and the like.

The invention relates to a high-thermal-conductivity modified polyphenyl ether material and a preparation method thereof. The polyphenyl ether material is prepared from, by weight, 5-50 parts of polyphenyl ether, 5-20 parts of polystyrene, 3-8 parts of toughening agent, 30-70 parts of thermal conductive filler, 0.2-3 parts of lubricant and 0.2-0.5 part of antioxidant. The polyphenyl ether material is prepared in the steps that 1, the thermal conductive filler and the lubricant are weighed and pre-mixed to obtain pre-mixed thermal conductive filler; 2, polyphenyl ether, polystyrene, the toughening agent and the antioxidant are weighed and mixed evenly with the pre-mixed thermal conductive filler to obtain a mixture; 3, the mixture is added in a screw extruder and subjected to melting, extruding, strip molding and cutting into particles to obtain the target product. Compared with the prior art, the polyphenyl ether material has the advantages of being good in processability, excellent in thermal conductivity, high in production efficiency and the like.

The invention belongs to the technical field of polyurethane solid waste recycling and specifically discloses a production method of solid waste particles of polyurethane foam powder, including the steps of mixing, compressing, counter-roll shaping, pressing roll granulation and sorting. The whole process goes through Four times of compression, and by adding adhesives to improve the bonding strength between polyurethane foam powder, can reduce the volume of solid waste of polyurethane foam powder by more than 15 times, and the particles have good compactness and uniform size. The invention can greatly reduce the transportation cost and storage cost of solid waste of polyurethane foam powder, and can be conveniently added to the production of boards such as wood-plastic flooring, effectively reducing the generation of dust, avoiding the occurrence of fire, and at the same time, it is well realized The reuse of waste resources reduces the production cost of panels.

The invention discloses efficient traditional Chinese medicine grinding equipment for a traditional Chinese medicine department. The efficient traditional Chinese medicine grinding equipment comprisesa shell body, wherein a control switch is mounted on the outer side face of the shell body. The efficient traditional Chinese medicine grinding equipment for the traditional Chinese medicine department is simple in structure; Chinese herbal medicines are processed and cut through a manner of firstly cutting and then grinding, so that tubers of the Chinese herbal medicines are further reduced andcan effectively fall into the lower side of a grinding disc, difficult blanking is avoided and the smoothness of a whole body is improved; a material pressing plate can move along the vertical direction and is matched with a separation plate to form a squeezes force, so that the Chinese herbal medicines can fall down from a through hole and are in effective contact with a rotary blade; a shieldingplate is arranged so that a condition that the Chinese herbal medicines are reflowed back into a feeding hopper when the material pressing plate squeezes is avoided; the chopped Chinese herbal medicines are ground and crushed by matching the grinding disc with a lining platform, so that the granularity of the Chinese herbal medicines is reduced; the discharging speed is controlled by a thread plate so that the Chinese herbal medicines stay for enough time between the grinding disc and the lining platform; a polishing path, which is longitudinally arranged, is convenient for discharging.
