Material grinding and conveying module and drying chamber thereof

Abstract

A material grinding and conveying module comprises a conveying platform composed of grid bar assemblies, a grinding device arranged above the conveying platform and a supporting frame. A first motor drives a first driving mechanism to drive the conveying platform to do reciprocating synchronous circular motion to bear and propel materials to advance; the grinding device comprises a grinding platform and a second driving mechanism; a second motor drives the second driving mechanism to drive the grinding platform to do reciprocating type synchronous circular motion perpendicular to the pushing direction of the materials to grind and scrape the materials; the second motor alternately performs forward rotation and reverse rotation, and the forward rotation time is equal to the reverse rotationtime. A drying chamber comprises a material grinding and conveying module, and the number of the material grinding and conveying module is one or more than one which are stacked. The grinding platform conducts grinding in the forward direction and the reverse direction, materials can be more evenly distributed on the conveying platform, the evaporation area is increased, and the drying efficiencyis improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of material drying equipment, and specifically refers to a material rolling conveying module and a drying chamber thereof. 【Background technique】 [0002] Material drying equipment is widely used in the drying process of chemical, food, medicine, building materials and other industries. In the field of sludge treatment, the mud cake produced by the sludge dewatering machine falls freely to the mesh crawler belt after granulation or slitting, and is transported by the multi-layer reciprocating mesh belt, and the moisture of the mud cake on the mesh belt gradually increases. Evaporate, and finally form a material with a lower moisture content to discharge. In the prior art, the drying efficiency of the mesh belt drying equipment is low, and the mud cake cannot be spread evenly in a short time after falling on the mesh belt, and the shape remains unchanged, and even the mesh belt will be ventilated by the fi...

Problems solved by technology

But, the inventor has found the following problems in the use process of this equipment: 1. In the specific embodiment of the specification disclosed in this invention patent, the rolling driving central axis of the rolling device is driven by the driving mechanism of the grid bar assembly. Driven by transmission, since the driving center shaft of the grid bar assembly is finally to push the material forward, it will take a long time for the rolling device linked with it to move to one side

When the material is rolled and moved to one side by the rolling device for a long time, it will form accumulation on one side, resulting in the uneven distribution of the material on the platform, which will affect the drying effect and the stability of operation.

2. The driving of the drive shaft in this patent document does not mention the scheme of directly driving the drive shaft through gears, and the several driving methods mentioned in the embodiments are likely to cause the drive shaft to be difficult to synchronize during operation or the structure is not stable enough

3. The rolling board does not mention the use of hollowed out boards. A rolling board without hollowing out will easily cause the materials falling from the ventilation slots of the upper layer of grid components to accumulate on the rolling board during the rolling process, which cannot be stabilized for a long time work

4. As a platform component, it must be installed in the drying room for use, which will cause heat leakage and loss, and reduce heat utilization efficiency

5. It is difficult to increase the drying area of ​​the platform by flexibly increasing the number of layers
