Description
[ technical field ] A method for producing a semiconductor device
The invention belongs to the technical field of material drying equipment, and particularly relates to a material conveying device with a spiral shaft spreading mechanism and a material conveying channel.
[ background of the invention ]
In the processes of solid-liquid separation and solid medicament infusion, a hopper is often adopted for temporary storage and preparation for feeding, but some viscous and easily hardened materials are easily adhered to the side wall of the hopper or form an overhead structure through the support of the side wall, so that the materials cannot be pushed and conveyed from top to bottom.
In addition, the material drying device is widely applied to drying processes in the industries of chemical industry, food, medicine, building materials and the like. In the field of sludge treatment, mud cakes produced by a sludge dewatering machine are finally formed into materials with lower water content and discharged after being crushed, granulated or stripped. The Chinese patent 201911093469.3 discloses a material conveying device with a screw shaft spreading mechanism, which is suitable for material drying equipment. The inventor finds that the device has the following disadvantages in the using process: 1. after the material is paved by the screw shaft paving device, the material enters the lower part of the material rolling device, and after the screw shaft paving device works for a long time, the material is found to be adhered to the rolling guide plate close to the side of the screw shaft paving device and cannot fall off. 2. The material blocking device only plays a material blocking role, but if feeding is too fast, the material can be stacked above the material blocking device, and finally falls out of the conveying platform. However, if the baffle plate is extended to form the side wall of the channel, the materials are easily adhered to the plate wall, and unsmooth blanking and spreading is caused. 3. The spiral blade at the tail end of the spiral shaft is too close to the edge of the conveying platform, so that materials are easily accumulated on the edge during material paving, and the materials are more easily accumulated on the edge after entering the material rolling device.

The specific working principle of the rolling drive mechanism 202 is the same as that of the drive mechanism disclosed in the reference, except that: the conveying platform driving mechanism and the rolling driving mechanism in the comparison document are in linkage, the rolling driving central shaft of the rolling driving mechanism is driven by the driving central shaft of the conveying platform driving mechanism, and the conveying platform driving mechanism and the rolling driving mechanism are in linkage with each other, so that the rolling plate can only passively move towards one direction. The conveying platform driving mechanism and the rolling driving mechanism are independent and are respectively arranged on two mutually vertical side surfaces. The second motor 203 alternately performs forward rotation and reverse rotation for a time equivalent to the reverse rotation time.

A rectangular support frame 400 is provided around the conveyor platform 100 and the material rolling device 200 to support the drive mechanism of the conveyor platform 100 and the rolling drive mechanism 202.
One side of the material rolling device 200 close to the screw shaft spreading mechanism 300 is provided with a side wall 204, a hollow plate 205 parallel to the side wall 204 is arranged close to the side wall 204, and two side edges of the hollow plate 205 are fixed on the supporting frame 400. The side wall 204 is driven by the material rolling device 200 to make reciprocating circular motion, and forms relative displacement with the closely attached hollow plate 205, so that the material accumulation of the side wall of the material rolling device 200 can be prevented.
The initial end 320 of the conveying platform 100 is tilted upwards and exceeds the height of the screw shaft, and forms a material conveying channel from top to bottom with the side wall 204 of the material rolling device 200 close to the spreading device of the screw shaft.
The screw shafts of the screw shaft spreading mechanism 300 of the embodiment are two screw shafts arranged side by side, the screw shaft close to the material conveying direction is a first screw shaft 301, and the screw shaft close to the starting end of the platform is a second screw shaft 302; the first screw shaft 301 and the second screw shaft 302 rotate in opposite directions; the material is phagocytized and crushed by the two screw shafts 301 and 302 due to the rotary motion of the two screw shafts 301 and 302, spread from the feeding end of the screw shafts to the tail end of the screw shafts, and spread to the position of the conveying platform 100 at the bottom of the two screw shafts.
The two ends of the two screw shafts 301 and 302 are spaced from the edge of the conveying platform 100, so that the materials are prevented from being deposited on the two ends of the screw shafts before entering the material rolling device 200. Or, the radial blades 303 are arranged at the positions without the helical blades at the two end parts of the two parallel helical shafts 301 and 302, and the helical central shafts are mutually scraped by the radial blades 303 on the two helical shafts, so that the materials are prevented from being adhered and accumulated on the central shaft at the tail end of the helical shafts.
