Description

Technical Field

[0001] This utility model relates to the technical field of flue gas pollutant treatment, dust removal, and desulfurization, and in particular to the technical field of a silo structure that prevents cracking and agglomeration. Background Technology

[0002] In the dust removal, desulfurization and other flue gas pollutant treatment industries, silo structures are commonly used to store various materials and extract them as needed. A silo generally consists of a silo body 1, a silo cone hopper 2, a silo trouser-shaped chute 3, and a slide valve assembly 6 and 7. During normal use, the slide valve assembly 6 and 7 are closed, and the material enters the silo through the upper inlet 8, filling the silo space. When the material is needed, it can be controlled by the slide valve assembly 6 and 7 to allow the material in the silo to flow through the silo cone hopper 2 and the silo trouser-shaped chute 3, and flow out from the material outlets 9 and 10, and the flow rate can be controlled.

[0003] The existing technology has the following defects: 1. In engineering practice, when some materials have particularly high density and the silo volume is also very large, the upper part of the silo trouser-shaped chute may tear due to stress concentration, which poses a huge safety hazard; 2. In engineering practice, some materials are prone to agglomeration and blockage of the outlet under high pressure at the top or at low temperature, especially when there are weld cracks, which can easily lead to a drop in temperature and blockage of the outlet. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a silo structure that prevents cracking and clumping, thereby reducing safety hazards and outlet blockage.

[0005] To achieve the above objectives, this utility model proposes a silo structure that prevents cracking and clumping, comprising a silo body, a silo cone, a silo trouser-shaped chute, a heating pipe, and a heating pipe-encased circular tube. The lower end of the silo body is provided with a silo cone, and the lower end of the silo cone is provided with a silo trouser-shaped chute. A heating pipe-encased circular tube is provided at the connection between the silo cone and the silo trouser-shaped chute. The heating pipe-encased circular tube is fixedly connected to the bifurcation of the silo trouser-shaped chute, and a heating pipe is provided inside the heating pipe-encased circular tube.

[0006] Preferably, the silo body has a material inlet on the upper side.

[0007] Preferably, the two branch pipes of the silo trouser-shaped chute are each equipped with a silo wall vibrator.

[0008] Preferably, the lower ends of the two branch pipes are respectively provided with material outlets, and each material outlet is provided with an electric slide valve.

[0009] Preferably, the rear end of the heating tube surrounding the circular tube is open and has a connecting flange. The heating tube has a fixed end, which is fixedly connected to the connecting flange by a number of bolt pairs.

[0010] The beneficial effects of this utility model are as follows: By fixing the heating tube wrapped around the circular tube and fixedly connecting it to the bifurcation of the silo's trouser-shaped chute, this utility model can effectively strengthen the bifurcation of the silo's trouser-shaped chute, effectively avoiding stress concentration that could cause the weld to tear at the intersection; and it also protects the heating tube; the heating tube inside the circular tube can achieve heating control of the silo, increasing the internal temperature of the silo, thereby effectively preventing the easy formation of clumps that block the outlet when the temperature is low. Compared with the prior art, this utility model can reduce safety hazards and the phenomenon of outlet blockage.

[0011] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0014] See Figure 1 , Figure 2 This utility model discloses a silo structure for preventing cracking and clumping, comprising a silo body 1, a silo cone 2, a silo trouser-shaped chute 3, a heating pipe 4, and a heating pipe-encased circular tube 11. The lower end of the silo body 1 is provided with the silo cone 2, and the lower end of the silo cone 2 is provided with the silo trouser-shaped chute 3. The connection between the silo cone 2 and the silo trouser-shaped chute 3 is provided with the heating pipe-encased circular tube 11. The heating pipe-encased circular tube 11 is fixedly connected to the bifurcation 12 of the silo trouser-shaped chute 3. The heating pipe 4 is provided inside the heating pipe-encased circular tube 11.

[0015] The upper side of the silo body 1 is provided with a material inlet 8.

[0016] Both branch pipes 31 of the silo trouser-shaped chute 3 are equipped with silo wall vibrators 5.

[0017] The lower ends of the two branch pipes 31 are respectively provided with material outlets 9 and 10, and electric slide valves 6 and 7 are respectively provided on the material outlets 9 and 10.

[0018] The heating tube is open at the rear end of the round tube 11 and is provided with a connecting flange 13. The heating tube 4 is provided with a fixed end 14, and the fixed end 14 and the connecting flange 13 are fixedly connected by several bolt pairs 15.

[0019] The working process of this utility model: This utility model discloses a silo structure for preventing cracking and caking. During operation, the heating pipe is wrapped in a circular tube 11 and fixedly connected to the bifurcation 12 of the silo's trouser-shaped chute 3. This effectively strengthens the bifurcation of the silo's trouser-shaped chute, preventing stress concentration that could lead to weld tearing at the intersection. It also protects the heating pipe 4. The heating pipe 4 is installed inside the circular tube 11, which enables heating control of the silo and increases the internal temperature of the silo. This effectively prevents caking and blockage of the outlet when the temperature is low. By setting up a silo wall vibrator 5, the bifurcation pipe 31 can be intermittently vibrated through electrical control to prevent material from caking and blocking the outlet.

[0020] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
