Novel movable silo for dry-mixed mortar

Abstract

The invention relates to a novel movable silo for dry-mixed mortar. The novel movable silo comprises a movable silo body which is provided with an air-blowing feeding structure, a discharging structure and an air outlet structure. The air-blowing feeding structure comprises a straight feeding pipe; one end of the straight feeding pipe is connected with a steering pipe connection assembly; the other end of the straight feeding pipe is connected with a bend feeding pipe; and the end of the bend feeding pipe is connected with a material guide pipe which is connected with a cage-shaped discharging pipe. The movable silo body comprises a silo cone; the discharging structure comprises a supporting part installed in the silo cone; a conical device is installed on the supporting part and connected with a vibration device which is connected to the side wall of the silo cone; and the conical device is connected with the cage-shaped discharging pipe. The air outlet structure comprises an air outlet pipe which penetrates through the interior of the movable silo body and is connected with a reducing valve. The novel movable silo is simple in structure, convenient to use, durable and convenient to operate, has no vulnerable part and has high practical value.

Description

technical field [0001] The invention relates to a mobile silo, in particular to a novel dry-mixed mortar mobile silo. Background technique [0002] In the application process of cement and dry-mixed mortar in construction engineering, the temporary storage of cement and mortar or the automatic mixing of water is realized through the sealed mobile silo placed on the construction site. The cement and mortar in the mobile silo are transported by special transport tankers Compressed air is used to send it into the silo by air blowing. There are following defects in the mobile silo in the prior art: [0003] 1. In order to avoid dust pollution accidents, dust removal facilities are generally used for dust removal. However, in the existing dust removal device, before and after the material in the vehicle is cleared, the amount of exhaust gas is large, the air pressure is high, and the air velocity is fast, which affects the normal operation of the dust removal device; [0004] 2...

Problems solved by technology

[0003] 1. In order to avoid dust pollution accidents, dust removal facilities are generally used for dust removal. However, in the existing dust removal device, before and after the material in the vehicle is cleared, the amount of exhaust gas is large, the air pressure is high, and the air velocity is fast, which affects the normal operation of the dust removal device;

[0004] 2. The traditional air-blow feeding structure of the mobile silo is that when the conveying pipe passes through the cone of the silo and reaches the top of the silo, multiple 45° elbows are used to redirect the mortar so that the mortar is sprayed vertically downward from the top of the silo Blowing material, during the operation process, due to the high-speed, high-pressure impact and friction of the mortar particles, it is easy to wear through the pipe bend of the conveying pipe at the top of the silo in a short period of time. Disorderly splashing at the top of the silo, causing material segregation

At the same time, after the pipe bends and wears through, the material changes its original movement direction, and part of the material enters the exhaust pipe that is also arranged at the top of the silo, which has a great impact on the waste gas treatment;

[0005] 3. In practical applications, the materials in the silo are affected by the air humidity, storage time and their own characteristics, which are prone to arching and material blocking during the unloading process.

The silo wall vibration method used to aid flow unloading enhances the compactness of the material in the silo, and the friction between the material and the wall of the silo and the extrusion force between the material and the material also increase accordingly, further causing the material in the silo to The formation of the arch material intensifies the occurrence of material blocking during the unloading process

At the same time, the central unloading method of the single-cone structure of the silo leads to the formation of "core pulling" of the materials in the silo during the unloading process. The difference in rolling speed leads to different falling speeds of large and small particles, resulting in material segregation, which seriously affects the quality of dry-mixed mortar
