Description

Technical Field

[0001] The invention relates to dust removal equipment, in particular to a mobile integrated dust removal silo. Background Art

[0002] In the production of nano-scale / micron-scale powders (silicon dioxide, carbon black, light calcium carbonate, etc.), the powders need to be dusted after crushing and transferred to a silo for storage. The commonly used dust collector is a bag-type dust collector. After dust removal in the bag-type dust collector, the material is transferred to a transfer silo for storage. However, the bag-type dust collector and the transfer silo are manufactured and placed separately.

[0003] The current bag dust collector and transfer silo have the following disadvantages:

[0004] In order to increase production capacity, bag dust collectors are generally designed to be large, and the powder falling to the bottom of the cone will form bridges and accumulate at the bottom of the cone, resulting in poor material discharge.

[0005] The dust collector has two gas ports, one for inlet and one for outlet. The upper part of the dust collection silo is rectangular (or circular) and connected, while the lower part is conical. The material specifications are single, and a large amount of material flushing is required when changing product types, resulting in huge material waste.

[0006] The dust collector and transfer silo need to be rotated separately, which takes up a lot of space and increases investment costs;

[0007] Transfer silos usually have multiple cone bottoms to form outlets corresponding to the subsequent process (packaging) equipment. When using the intermediate silo, the material falls unevenly at the cone bottom, resulting in uneven material at the cone bottom, which seriously affects the production capacity of the packaging machine. At the same time, each silo can only hold one product, which makes it impossible to store multiple varieties and achieve production adjustments.

[0008] During use, packaging specifications and methods vary, and packaging machines also vary in size. Silos are usually fixedly connected to packaging equipment. When the packaging specifications required by the market (such as small packages or ton packages) change, they become very passive and difficult to adjust. The packaging flexibility is limited, which has a serious impact on actual production. Summary of the Invention

[0009] In order to solve the defects of the above-mentioned prior art, the present invention provides a mobile integrated dust removal silo. The present invention combines dust removal equipment with the silo, can process different materials at the same time, can be connected to different packaging machines at the same time, can be moved to the required position, is easy to use and highly efficient.

[0010] In order to achieve the above technical objectives, the present invention adopts the following technical solutions: a mobile integrated dust removal silo, comprising a dust removal body, at least two independent dust removal cavities are arranged inside the dust removal body, each of the independent dust removal cavities is provided with an air inlet, a crusher discharge pipe can be connected to one or more of the air inlets, a funnel silo is provided at the lower end of each of the independent dust removal cavities, an air outlet pipe is provided above the dust removal body, and the air outlet pipe is connected to the at least two independent dust removal cavities; the funnel silo is provided with a silo discharge pipe, and the silo discharge pipe is used to connect to a packaging machine; the dust removal body can be moved.

[0011] At least one partition is provided inside the dust removal body, and the partition divides the dust removal body into at least two independent dust removal cavities. The lower ends of at least two independent dust removal cavities are respectively connected to one of the funnel silos, and the upper ends share the air outlet pipe.

[0012] A fan is provided at the cone bottom of the hopper silo, the fan is used as a discharge pipe of the silo, and the outlet of the fan is used for docking with a packaging machine.

[0013] A high-pressure air pipe is also provided in the funnel silo. The high-pressure air pipe is provided with a plurality of nozzles, and the nozzles are used for blowing air toward the bottom of the cone. A pneumatic stirrer is also provided in the funnel silo.

[0014] The air outlet pipe is provided with a pulse air pipe and an air outlet connecting pipe. The pulse air pipe is provided with a plurality of branch pipes arranged in the funnel silo. The air outlet connecting pipe is connected to the induced draft fan for discharging clean gas.

[0015] The crusher discharge pipe is provided with a regulating valve and a flow monitoring meter.

[0016] The independent dust removal cavity is also provided with a flow velocity measuring instrument, which is used to detect the wind speed of the independent dust removal cavity and to adjust the wind speeds of at least two of the flow velocity measuring instruments to be consistent.

[0017] The dust removal body is further provided with a lifting lug, and the lifting lug is used for lifting so as to move the dust removal body.

[0018] A support frame is also provided, and a fixing plate is provided on the support frame, and the fixing plate is used for fixing the fastening plate connected to the dust removal body.

[0020] The reasonable distribution of the feed inlet of the present invention effectively solves the location of material falling, and can relatively average the amount of material in each cone bottom bin, so that there will be no material imbalance in each cone bottom.

[0021] The silo of the present invention can be used to hold one type of material or multiple types of materials, and can be used for one type of packaging or multiple types of packaging. The conical bottom feed port of the same material in multiple types of packaging can correspond to different packaging machines. At the same time, through the series connection of the dust removal air inlet, the feed position of the crusher can be adjusted according to demand, which facilitates the adjustment of packaging specifications and greatly enhances flexibility, thus realizing single-specification packaging of diversified varieties and multi-specification packaging of a single variety.

[0022] The present invention adopts a flat rod stirring device with high-voltage pulse to solve the material bridging and agglomeration problems and enhance the fluidity of powder materials.

[0023] The present invention utilizes the dust collector silo as the packaging silo, effectively combining the dust collector and the silo, and reducing equipment investment;

[0034] Example:

[0035] Figure 1It is a mobile integrated dust removal silo, including a dust removal body 1, wherein at least two independent dust removal cavities 101 are arranged inside the dust removal body 1, each of the independent dust removal cavities 101 is provided with an air inlet 102, and a crusher discharge pipe 401 can be connected to one or more of the air inlets 102, so that a silo can be connected to one or more crushers and can process one or more materials, and a funnel silo 2 is provided at the lower end of each of the independent dust removal cavities 101, and an air outlet pipe 3 is provided above the dust removal body 1, and the air outlet pipe 3 is connected to the at least two dust removal independent cavities 101; the funnel silo 2 is provided with a silo discharge pipe, and the silo discharge pipe is used to connect to the packaging machine; the dust removal body 1 can be moved.

[0036] The funnel silo 2 of the present application is both the discharge funnel of the bag dust collector body and is used as a silo. The outlet of the funnel silo 2 is connected to the packaging machine, replacing the solution in the prior art that the dust removal equipment sends the material to an additional silo through its own discharge funnel, and then uses the multiple funnels of the silo to discharge the material to the packaging machine. The present application adopts a combination of dust collector and silo, and uses the material collection funnel below the dust removal equipment as a transfer silo storage area. The discharge pipe reserved at the bottom of the transfer silo storage area can be connected to various types of packaging machines.

[0037] Specifically, at least one partition is provided inside the dust removal body 1, and the partition divides the dust removal body 1 into at least two independent dust removal cavities 101. The lower ends of at least two independent dust removal cavities 101 are respectively connected to a funnel silo 2, and the upper ends share the air outlet pipe 3.

[0038] Figure 1 As shown, there are two partitions, which divide the dust removal body 1 into three independent dust removal chambers 101. The three independent dust removal chambers 101 are isolated from each other and share the upper air outlet pipe, while the lower funnel silo 2 is independent. This allows one independent dust removal chamber 101 to process one material, so that one dust removal body 1 can process three materials, and any two independent dust removal chambers 101 can process one material at the same time, or three independent dust removal chambers 101 can process one material together. That is, a dust removal device of the present application can process at most the same number of materials as the independent dust removal chambers 101, so that the dust removal device of the present application is more efficient, which solves the defect in the prior art that a bag dust removal device can only process one material.

[0039] The present application sets a funnel silo 2 corresponding to an independent dust removal chamber 101. All materials in the independent dust removal chamber 101 can only fall into the funnel silo 2, solving the problem in the prior art that materials in a silo fall into multiple funnels at the same time, resulting in uneven distribution.

[0040] Figure 2This is a schematic diagram of a hopper silo. Figure 1 The specific structure of the hopper silo is not shown in the figure. The cone bottom of the hopper silo 2 is provided with a fan 7. The fan 7 is used as the silo discharge pipe. The outlet of the fan 7 is used to connect the packaging machine. The application uses the fan 7 to discharge the material well.

[0041] A high-pressure air pipe 8 is further provided in the funnel silo 2 . The high-pressure air pipe 8 is provided with a plurality of nozzles 801 . The nozzles 801 are used for blowing air toward the bottom of the cone. A pneumatic stirrer 9 is also provided in the funnel silo 2 .

[0042] The high-pressure air pipe 8 is connected to the air source, and a solenoid valve is provided at the air source. The high-pressure air pipe 8 can solve the problem of uneven material falling, and the pneumatic agitator 9 can solve the problem of material agglomeration. The pneumatic agitator 9 can be a pneumatic telescopic tube, which extends into the interior of the funnel silo 2 and has a stirring rod provided therein. The exterior of the telescopic tube is controlled by compressed air. The telescopic tube is pulled horizontally, and the stirring rod is used to pull the material between each pull and retraction to prevent the material from agglomerating.

[0043] The present invention modulates the high-pressure pulse injection point at the conical bottom of the silo, and the high-pressure air pulse is injected into the conical bottom, and the air pressure impacts the material downward. The present invention installs a flat rod stirring device 9 at the connection between the conical bottom and the silo, which stirs slowly by pneumatic means to prevent the material from agglomerating.

[0044] like Figure 1 As shown, the outlet pipe 3 is equipped with a pulse air pipe 5 and an outlet connecting pipe 301. The pulse air pipe 5 has multiple branch pipes installed in the funnel silo. The outlet connecting pipe 301 is connected to the induced draft fan 6 to discharge clean air. When a certain amount of powder is adsorbed on the filter bag, a high-pressure pulse is used to shake the powder off to the bottom of the cone.

[0045] The crusher discharge pipe 401 is equipped with a regulating valve 402 and a flow meter. The number of discharge pipes in this application is related to the crusher's production capacity. When a crusher has multiple discharge pipes, each discharge pipe requires a regulating valve and flow meter. A single discharge pipe does not require these valves or meters. The crusher discharge pipes can be connected in series, allowing them to be adjusted to different feed bins based on packaging requirements.

[0046] The independent dust removal chamber 101 is further provided with a flow velocity measuring instrument, which is used to detect the wind speed of the independent dust removal chamber 101 and to adjust the wind speeds of at least two of the flow velocity measuring instruments to be consistent.

[0047] The present application sets a separate air inlet 102 for each independent dust removal chamber 101, and the air inlet 102 can be connected to the crusher discharge pipe 401. The dust collector air inlet of the present application adopts multiple air inlet (dust) points, and multiple independent silos are formed between the air inlet (dust) points and the lower cone bottoms. The top air induced system is shared, and flow velocity meters are designed at the air inlet to balance the air intake volume to prevent the wind speed in a certain cavity from being too high and the wind speed in other cavities from being too low.

[0048] The dust collecting body 1 is further provided with a lifting lug 12, which is used for lifting to move the dust collecting body 1. The dust collecting silo of the present application is designed to be movable and can be moved by an overhead crane, which is convenient for maintenance and replacement to a suitable location.

[0049] Figure 3 This is a schematic diagram of loading the dust collector body onto the support frame. Figure 3 Hidden Figure 1 Part of the structure is also equipped with a support frame 10, and the support frame 10 is provided with a fixing plate 1001, and the fixing plate 1001 is used to fix the fastening plate 11 connected to the dust removal body 1.

[0050] Multiple support frames 10 are fixed in various places in the workshop. When dust removal is needed in a certain place, the dust removal body 1 is hung and installed on the support frame 10 at that place, so that the dust removal equipment of the present application is mobile and can be transported to various places in the workshop.

[0051] The silo of this application is supported by being fixed on a steel column, with lifting ears installed on both sides for use during hoisting. The silo is kept at a certain distance from the column, making it easy to enter and exit during hoisting. The packaging machine is located at the bottom of the silo, and the packaging machine can be placed in various combinations. The feeding pipe of the packaging machine is connected to the cone-bottom air-blower, and the middle of the silo is isolated. The feeding pipe of each silo can come from different crushers or the same crusher. Different types / specifications of crushed products can be stored in different cones of a mobile silo. It is only necessary to connect the feeding pipe of the packaging machine to the discharge pipe at the cone-bottom. With the same equipment, a multi-variety / multi-specification packaging scenario can be achieved. When there are many packaging machine areas and few dust removal silos, they can be hoisted to different packaging machine areas for packaging according to the requirements of packaging specifications or product types. The flexibility is greatly improved, which can effectively solve the packaging process of multi-variety / multi-specification silica powder materials and is conducive to the design and planning of dust-free centralized packaging workshops.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
