Description

Technical Field

[0001] The utility model relates to a material conveying and distributing system. Background Art

[0002] The Shawan sludge treatment facility and resource utilization project is the first fertilizer production project in Tacheng area, with a total investment of more than 18 million yuan. The daily sludge processing capacity (water content 60%) is about 15 tons. The process adopted is tank fermentation. The tank fermentation section adopts a closed space to facilitate the maintenance of fermentation temperature and odor collection and treatment.

[0003] The tank fermentation process is also a very mature process in China. After the sludge, auxiliary materials and bacteria are completely stirred and mixed, they enter the tank aerobic fermentation tank. After 15 days of normal fermentation with periodic turning, the sludge is fermented into fertilizer. The fertilizer produced is mainly used for the city's landscaping, truly realizing the reduction, stabilization, harmlessness and resource utilization of sludge.

[0004] The original design of the production process was that the mixed materials of sludge, auxiliary materials and bacterial strains were transported to the fermentation tank by a forklift. Therefore, the operation mode of the entire material mixing system was intermittent, and the transportation cycle was long. The forklift had to go back and forth in and out of the closed space of the fermentation tank, resulting in the leakage of harmful gases such as odor in the closed space of the fermentation tank, and the health and safety of personnel could not be guaranteed. Summary of the invention

[0005] The utility model aims to provide a material conveying and distributing system, which is used to replace a forklift to transport materials, operates continuously, and prevents personnel and machinery from entering the closed space of a fermentation tank.

[0006] The technical solution is: a material conveying and distribution system, which is composed of a first material horizontal conveying equipment and a second material horizontal conveying equipment arranged vertically to each other in a horizontal plane, a material vertical lifting equipment is arranged at the feeding end of the first material horizontal conveying equipment, and a material mixing equipment is arranged at the lower end of the material vertical lifting equipment; a No. 1 plug-in control valve and a No. 2 plug-in control valve are respectively arranged on one side of the second material horizontal conveying equipment, and the two material horizontal conveying equipment are respectively installed above the production workshop through an equipment hanger and an equipment support frame.

[0007] The space layout of the on-site fertilizer workshop is limited. In order not to affect the walking space and route of the original forklift, a material vertical lifting device is designed and installed at the discharge end of the existing material mixing equipment to directly lift the mixed material to the designed height. This installation height takes into account the normal passage of the forklift and the top elevation of the fermentation tank supporting the turner to ensure that the installed conveying and distribution equipment does not affect the normal operation of the turner. Two material horizontal conveying devices are designed at the rear end of the material vertical lifting equipment to transport the material horizontally to the closed space of the fermentation tank. After entering the closed space of the fermentation tank, a plug control valve is set above the top of the 1# and 2# fermentation tanks to realize the mixed material into the corresponding fermentation tank according to the production process requirements.

[0008] Compared with the prior art, the advantages of the utility model are: 1. The mixed material conveying is continuous and the conveying cycle is short; 2. Operation in the low temperature period effectively avoids the heat loss in the closed space of the fermentation tank; 3. Avoids the leakage of harmful gases such as odor, and improves the recovery efficiency of harmful gases; 4. Effectively prevents operators from directly entering the fermentation tank to ensure personal health and safety; 5. Reduces the frequency of use of forklifts and reduces the cost of use and maintenance; 6. The three-dimensional installation of the equipment occupies a small space; 7. The structure is simple and easy to disassemble, install and repair. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] In the above-mentioned Figure 1 , 23: A material conveying and distribution system, which is composed of a first material horizontal conveying equipment 3 and a second material horizontal conveying equipment 5 which are arranged vertically to each other in a horizontal plane, the feeding end of the first material horizontal conveying equipment 3 is provided with a material vertical lifting equipment 2, and the lower end of the material vertical lifting equipment 2 is provided with a material mixing equipment 1; a No. 1 plug-in control valve 7 and a No. 2 plug-in control valve 8 are respectively provided on one side of the second material horizontal conveying equipment 5, and the two material horizontal conveying equipment are respectively installed above the production workshop through an equipment hanger 6 and an equipment support frame 4.

[0015] Equipment working process: sludge, auxiliary materials and bacteria are added to the material mixing equipment 1 according to the design requirements. After being fully mixed, they enter the material vertical lifting equipment 2 from the discharge port. The mixed materials are directly vertically lifted to the design required height and then enter the material horizontal conveying equipment 3 and the subsequent material horizontal conveying equipment 5. After the mixed materials are horizontally conveyed into the closed space of the fermentation tank, they are divided into 3 situations for description:
