Description

Technical Field

[0001] The present application relates to a silo for a particle mixture. Background Art

[0002] The production of dry-mixed mortar is to mix multiple materials together to obtain a mixture that is as uniform as possible. The mixed materials need to be temporarily stored in a silo before being bagged and packaged. The silo is generally in the shape of a funnel with a discharge port at the bottom. The material enters the silo from the upper feed port and enters the packaging machine from the lower discharge port.

[0003] Since dry-mixed mortar is mainly a mixture of granular materials (sand and gravel) and loose powder materials (cement, fly ash, etc.), during the packaging process, as the materials decrease, different materials will be separated due to their different properties (for example, density, particle size, etc.) and the inclined surface of the silo, which will cause large deviations in the product composition of the tailings packaging and unstable product performance. Utility Model Content

[0004] The purpose of this application is to fluidize the material in the silo and eliminate material segregation.

[0005] To this end, the present application provides a silo for a particle mixture, including a compressed air pulse component, wherein the compressed air pulse component includes a compressed air pulse generator and a compressed air pulse delivery pipeline connected to the compressed air pulse generator.

[0006] Furthermore, the compressed air pulse pipeline includes a main pipe and at least one branch pipe connected to the main pipe, wherein the inlet of the main pipe is connected to the compressed air pulse outlet of the compressed air pulse generator, and the branch pipe is configured to extend inside the silo.

[0007] The lower part of the silo has at least one discharge port and an inclined portion surrounding the discharge port, and the outlet of the branch pipe is configured to be adjacent to the inner surface of the inclined portion. Further, the outlet of the branch pipe is configured to be adjacent to the inner surface of the inclined portion adjacent to the discharge port. Further, the branch pipe is provided with a control valve.

[0008] Wherein, the inner cavity of the silo is configured as a cone.

[0009] The silo of the present application can utilize the pulse shock wave of compressed air to agitate the material, effectively improve the material segregation, and thus improve the product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The specific implementation of the present application is described below with reference to the accompanying drawings.

[0017] In the present application, the terms "upper" and "lower" refer to directions in the vertical direction.

[0018] Figure 1 In one embodiment of the present application, a silo 100 includes a silo body 110 and a compressed air pulse assembly 120 .

[0019] The silo body 110 is generally funnel-shaped, and its inner cavity is generally conical, for example, it can be a circular cone or a square cone. Figure 2 The lower part of the silo body 110 has at least one discharge port 112 and an inclined portion 114 surrounding the discharge port 112. The upper part of the silo body 110 has a feed port and an exhaust port.

[0020] The compressed air pulse assembly 120 includes a compressed air pulse generator 122 and a compressed air pulse delivery pipeline 124 .

[0021] The compressed air pulse line 124 includes a main pipe 1242 and at least one branch pipe 1244. Figure 1 In the embodiment shown, four branch pipes 1244 are connected to the main pipe 1242. In other embodiments, the number of branch pipes can be determined according to actual applications. The inlet of the main pipe is connected to the outlet of the compressed air pulse generator 122.

[0022] The compressed air pulse generator 122 can be obtained through commercial channels and can be any suitable device. The compressed air pulse generator 122 transmits compressed air in pulses into the main pipe 1242 and then enters each branch pipe 1244 through the main pipe 1242 .

[0023] Despite Figure 1 In the illustrated embodiment, the branch pipe enters the interior of the silo body 110 from the upper portion. However, the arrangement positions of the main pipe and the branch pipe may vary according to the actual application environment.

[0024] Reference Figure 3 , each branch pipe 1244 extends at a different position inside the silo body 110. The terminal outlet of the branch pipe 1244 may be adjacent to the inner surface of the inclined portion 114. For example, it may be located at a position relatively above the inclined portion. Alternatively, the outlet of the branch pipe 1244 may also be adjacent to a position relatively below the inclined portion, such as a portion adjacent to the discharge port. The outlets of the multiple branch pipes are configured to be located at different positions in the silo, which may be beneficial for fluidizing materials at different locations. The fluidization is to blow up and mix the materials by compressed air.

[0025] A control valve 130 is provided at the location where each branch pipe 1244 is connected to the main pipe 1242 to control the opening and closing of the branch pipe 1242, thereby controlling the position inside the silo to which the compressed air pulse is delivered. The control valve can be a one-way valve, or it can be closed after the compressed air pulse passes through to prevent the raised material from entering the main pipe.

[0026] In the above description, the details of the technical solution of the present application are explained. However, those skilled in the art will appreciate that the present application is not limited to the specific details listed in the above embodiments, but may vary within the scope defined by the claims.
