Description

Technical Field

[0001] This utility model belongs to the technical field of yam powder production equipment, specifically relating to a pulverizer for yam powder production. Background Technology

[0002] In the production of yam powder, various raw materials need to be pulverized into powder and then mixed. The mixed powder is then expanded using an extruder. The expanded material is then segmented and further pulverized by a grinder to produce finished yam powder. In existing technologies, the expanded material contains a high temperature, which is detrimental to subsequent pulverization, resulting in poor pulverization effect and low pulverization efficiency. Furthermore, the material pulverized at high temperatures is prone to caking when exposed to air, reducing the quality of the yam powder. Using natural cooling before pulverization is time-consuming and affects production efficiency. Therefore, there is an urgent need for a grinder for yam powder production to solve the above technical problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a pulverizer for yam powder production. The pulverizer includes a pulverizer body, with a cooling and pre-crushing mechanism connected to the feed inlet. The discharge outlet of the pulverizer body is connected to a dust collector via a conduit, and the discharge outlet of the dust collector is connected to a dispersing mechanism. Before pulverization, the material undergoes pre-crushing and cooling, improving the pulverization effect and efficiency. After pulverization, the material passes through the dust collector for solid-gas separation and then enters the dispersing mechanism for effective dispersal, resulting in more thorough pulverization and preventing excessive heat and material agglomeration. Preferably, the cooling pre-crushing mechanism includes a feeding auger, which includes a housing and a feeding paddle. One end of the housing is provided with a feed hopper, and the other end of the housing is provided with a discharge pipe. The discharge pipe is connected to the feed inlet of the crusher body. The housing is provided with a cooling jacket, which is provided with a cooling medium inlet and a cooling medium outlet. The feeding paddle includes a rotating shaft and spiral feeding blades fixed on the rotating shaft. The two ends of the rotating shaft pass through the two ends of the housing and are rotatably connected to the housing through bearings. The rotating shaft is provided with a cooling channel. The two ends of the cooling channel pass through the two ends of the rotating shaft and are respectively connected to a liquid inlet pipe and a liquid outlet pipe through a rotary joint. A pulley is fixed on the rotating shaft outside the housing. The pulley is engaged with a pulley, and the pulley is connected to the pulley via a transmission belt. The pulley is connected to a motor. Before entering the main body of the crusher, the material is first transported in the feeding auger. During the transport process, it is cooled and pre-crushed. The cooling jacket and the rotating shaft effectively cool the material entering the feeding auger from both inside and outside, which helps to improve the crushing effect and crushing efficiency of the crusher.

[0004] Preferably, the dispersing mechanism includes a housing, with an inlet at one end connected to the outlet of the dust collector, and a discharge pipe with a switch valve at the other end. A dispersing assembly is located inside the housing, comprising a second rotating shaft. One end of the second rotating shaft passes through one end of the housing and is connected to a second motor. Multiple dispersing blades are arranged spirally on the second rotating shaft within the housing. The blades are shovel-shaped, and a threaded rod is fixedly connected to the end of each blade near the second rotating shaft. The second rotating shaft has through holes that mate with the threaded rods, and the threaded rods pass through the corresponding through holes. Locking nuts are provided on the threaded rods on both sides of the through holes. With this configuration, the second motor drives the second rotating shaft to rotate, and the dispersing blades disperse the material inside the housing, reducing agglomeration. Simultaneously, the spiral arrangement of the blades facilitates material transport. Material falling from the dust collector enters one end of the housing and is simultaneously dispersed and transported towards the discharge pipe by the dispersing assembly.

[0005] Preferably, the cross-section of the second rotating shaft is a regular polygon. This facilitates the installation of the disassembled pieces and the fixing of the locking nut.

[0006] Preferably, the top of the housing is provided with an openable cover.

[0007] Preferably, the dust collector is a cyclone separator. It separates the solid and gas components of the material after it has been pulverized by the crusher. This separation results in cleaner exhaust air and reduces dust pollution during production.

[0008] This utility model also includes other components that enable a pulverizer for yam powder production to operate normally, such as control components for the pulverizer body, control components for motor one and motor two, control components for the dust collector, fan connected to the dust collector, control components for the cyclone separator, control components for controlling the liquid inlet of the medium (such as a liquid pump), and control components for controlling the liquid inlet of the cooling channel (such as a liquid pump). These are all conventional technical means in the field, common knowledge, and commonly used equipment in the field.

[0009] Working principle: Before being pulverized, the puffed material is pre-crushed and cooled, which improves the pulverization effect and efficiency. After being pulverized, the material is separated into solid and gas by a dust collector and then enters the dispersing mechanism to effectively disperse the material, making the pulverization more thorough and avoiding excessive heat and agglomeration of the material.

[0010] Specifically, coolant (cold water, cold oil, etc.) is continuously circulated into the cooling jacket and cooling channels of the feeding auger. Material enters the feeding auger for transport, where it is cooled and pre-crushed. The cooling jacket and rotating shaft effectively cool the material entering the feeding auger both internally and externally, improving the crushing effect and efficiency of the crusher. The pre-crushed and cooled material enters the crusher for further crushing. The crushed material passes through a dust collector, and clean air is discharged through the dust collector's outlet, carrying away some heat. The material enters the machine casing from the dust collector's outlet and is simultaneously dispersed by the dispersing component as it is transported towards the discharge pipe.

[0011] This invention has the following beneficial effects: it can pre-crush and cool the puffed raw materials used to produce yam powder, improving the crushing effect and efficiency of the crusher. After crushing, the material passes through a dust collector for solid-gas separation and then enters the dispersing mechanism, making the exhaust air cleaner and removing some heat, reducing dust pollution during the production process. It can effectively disperse the material, making the crushing more thorough and avoiding excessive heat and clumping of the material. This is beneficial to improving the quality of yam powder and production. Attached Figure Description
