AI Technical Summary
During the long pipeline transportation process, the material flow rate drops due to pressure loss and pipeline resistance, which is prone to blocking and burning of pipes. Especially in the case of multiple use points, the material and air flow mix unevenly, resulting in uneven pressure and poor distribution. The problem is even.
A micro powder conveying and spraying system is designed, including a material tank, an inner-shell gas balancer and a multi-channel gas balance equalizer. By reducing the air pressure resistance and uniformly mixing the gas and materials again, the air pressure is increased to ensure that the material is complete. Suspension and smooth transportation solve the problems of pipe-blocking and uneven mixing.
It effectively improves the material flow rate, reduces material sinking, ensures uniform mixing of airflow and materials, avoids pipe blockage, and realizes reliable transportation of multiple distributions.

Description
Technical Field
[0001] The utility model belongs to the technical field of micro powder conveying and uniform spraying systems, in particular to a micro powder conveying and uniform spraying system. Background Art
[0002] The existing material and bag ash conveying systems in the market industry all adopt the principle of powder dense phase conveying, and realize the material conveying process after combining with reasonable equipment. The blast furnace coal powder injection system adopts the principle of high-pressure coal powder dense phase conveying system, and uses nitrogen to pressurize and continuously convey coal powder to the blast furnace at a high solid-gas ratio through pipelines.
[0003] The current spraying system adopts the existing dense phase pneumatic conveying principle in the industry. After the gas is introduced from the spraying tank through the pipeline conveyor, the gas and material are mixed in proportion by the nozzle, concentrated in the manifold, and then distributed to each use point by the distributor before spraying. Due to the long pipeline process, the increase of pipelines and the loss of pressure, the resistance loss in the pipeline is large. When there are multiple use points of the material at the end of the pipeline, the pressure in the pipeline will inevitably drop greatly, and the material flow rate will become lower. When the material in the pipeline is less than the critical flow rate value, the granular material will sink and accumulate on the lower wall of the pipeline, gradually forming the phenomenon of blocking the pipe and burning the gun. Utility Model Content
[0004] In order to solve the problems raised in the above background technology, the utility model provides a micro powder conveying and uniform spraying system, which can solve the problem that the material of the existing blowing and spraying system is prone to hit the lower wall of the pipeline and block the pipe and burn the gun during operation.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a micro-powder conveying and spraying system, including a material tank, a connecting assembly is provided at the bottom of the material tank, a material pipe is fixedly connected to the bottom of the connecting assembly, one end of the material pipe is fixedly flanged with an inner-shell type material-gas balancer, one side of the inner-shell type material-gas balancer is fixedly flanged with a conveying pipe, and one end of the conveying pipe is fixedly flanged with a multi-channel material-gas balance equalizer.
[0006] Preferably, the connection assembly includes a connection ring, the edge of the bottom of the connection ring is fixedly connected to the top of the material pipe, the outer surface of the connection ring is fixedly connected to a spring, and one end of the spring is fixedly connected to a resistance piece.
[0007] Preferably, air inlet pipes are inserted on both sides of the top of the inner-shell type material-gas balancer, and a cavity channel is opened inside the inner-shell type material-gas balancer.
[0008] Preferably, a connecting plate is fixedly connected to one side of the surface of the conveying pipe, and fixing bolts are threadedly penetrated at the four corners of the surface of the connecting plate.
[0009] Preferably, a fixing plate is threadedly connected to one side of the surface of the fixing bolt, a through groove is opened in the middle of the surface of the fixing plate, and the inner diameter of the through groove is matched with the diameter of the conveying pipe.
[0010] Preferably, an observation window is provided on the surface of the material tank, and a transparent plate is embedded on the surface of the observation window.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] 1. This device uses a material tank, an inner-sheathed material-gas balancer and a multi-channel material-gas balance divider to balance the airflow in the material pipe when the staff uses the material tank to transport the material to the inside of the material pipe, thereby reducing the air pressure resistance and increasing the material flow rate to reduce the chance of material sinking.
[0013] 2. This device is equipped with a material tank and a multi-channel material-gas balance distributor. When the material enters the inner-inner-outer material-gas balancer, the air inlet pipe transports the gas to the inner-inner-outer material-gas balancer, so that the internal material and the gas source are evenly mixed again before being dispersed for use, and the problems of multiple use points, uneven pressure, and uneven distribution are solved. The air pressure is increased again through secondary air replenishment, so that the material can be completely mixed and suspended in the pipeline and transported smoothly, finally achieving the goal of multi-channel distribution of materials and solving the problem of uneven mixing of airflow materials and pipe clogging and gun burning.
[0014] 3. This device is connected with the setting of the material tank. When the staff needs to install the material tank to the top of the material pipe, the staff can squeeze the resistance piece to compress the spring, and then place the material tank on both sides of the resistance piece. Then the staff loosens the resistance piece to make the resistance piece free from the constraint. Then the spring drives the resistance piece to quickly resist and fix the material tank, so as to facilitate the staff to quickly fix and install the material tank. BRIEF DESCRIPTION OF THE DRAWINGS
