Background

In the process of conveying solid materials, an air conveying chute is taken as main material conveying equipment, the air conveying chute is divided into an upper part and a lower part by a material partition plate, a feed inlet is positioned above the material partition plate, the solid materials fall into canvas on the material partition plate from the feed inlet, a blower blows compressed air to the lower part of the material partition plate to blow the solid materials out of a discharge outlet, and gas is discharged from an exhaust outlet.

In the actual production process, because carbide slag cement production line's self characteristics, contain a large amount of coarse grained matter (containing ferrosilicon) in carbide slag dry powder and the raw material powder of mixing carbide slag dry powder, behind the coarse grained matter fell into the ventilative canvas on the material baffle from the feed inlet, it is serious to the wearing and tearing of the ventilative canvas of chute, lead to chute feed inlet below to receive material to strike position canvas and frequently damage, often need shut down the maintenance and change the canvas, and shut down and overhaul not only can cause a large amount of materials extravagantly, and seriously restrict production line continuous steady operation.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving above-mentioned technical problem to a certain extent at least. Therefore, the utility model provides an air conveying chute with double-deck splint canvas to can improve the problem that leads to needing frequent shut down to overhaul because of air chute canvas life is short.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an air conveying chute with double-deck splint canvas, the inner chamber is as material transport area territory to separate by the material baffle and form upper trough of area territory and lower trough of area, chute one end top is equipped with the feed inlet, and the bottom of the other end is equipped with the discharge gate, the top is equipped with the gas vent, and the chute is on the cell wall that is located the feed inlet homonymy, the high position department that is less than the material baffle is equipped with the air inlet that provides highly-compressed air by the air-blower, from the air inlet spouts the high-pressure air flow direction of lower trough of area and sets up along material direction:

a double-layer clamping plate canvas assembly is arranged on the material partition plate corresponding to the position right below the feeding hole; the double-layer splint canvas assembly comprises an upper layer of air chute canvas, a middle microporous steel plate and a lower layer of air chute canvas; the lower layer air chute canvas is detachably fixed on the bottom end face of the middle microporous steel plate to form a lower layer canvas component, and the upper layer air chute canvas is detachably installed on the top end face of the middle microporous steel plate to form the double-layer splint canvas component together with the lower layer canvas component;

the upper groove area and the lower groove area utilize the double-layer clamping plate canvas assembly as a ventilation layer, and high-pressure air entering the lower groove area enters the upper groove area through the ventilation layer.

Further, the lower layer of air chute canvas and the middle microporous steel plate and the upper layer of air chute canvas are fixed by bolts.

Compared with the prior art, the utility model discloses beneficial effect embodies:

the utility model discloses an increase one deck air chute canvas and micropore steel sheet again on original one deck air chute canvas's basis, make former chute feed inlet below bear the canvas breakage rate reduction at solid-state material impact position, reduced the frequency of shutting down the maintenance, guaranteed the continuity of production, effectively avoided the waste of material, provide the necessary condition for continuous stable production.

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1 an air delivery chute; 2, a feeding hole; 3, a blower; 4, discharging a material outlet; 5 an exhaust port; 6, upper layer air chute canvas; 7 middle microporous steel plate; 8, lower layer air chute canvas; 9 material partition board.

Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Currently, an air conveying chute is a conveying device which uses air to make solid materials flow downwards along the chute in a fluidized state, and the existing structure is as follows: the inner cavity is used as a material conveying area, the upper groove area and the lower groove area are formed by separating a material partition plate 9, a feeding hole 2 is formed in the top of one end of the chute, a discharging hole 4 is formed in the bottom of the other end of the chute, an exhaust hole 5 is formed in the top of the chute, an air inlet through which high-pressure air is provided by an air blower 3 is formed in the position, on the wall of the chute, located on the same side with the feeding hole 2, of the chute and lower than the material partition plate 9, and the airflow direction of the high-pressure air which is sprayed. The working principle is that the solid material falls into canvas arranged on the material partition plate 9 from the feeding port 2, high-pressure air is sprayed into the lower groove area through the air inlet by the air blower 3 and enters the upper groove area through the canvas, the solid material in the upper groove area is in a flow state under the action of air flow and flows under the action of gravity to achieve the purpose of conveying, the solid material is blown out from the discharging port 4, and the gas is discharged from the gas outlet 5.

Referring to fig. 1, the air conveying chute with double-layer canvas sheets of the present embodiment is provided with double-layer canvas sheet assemblies at the positions for mounting the canvas sheets on the material partition plate 9, that is, at the positions right below the feed ports 2; the double-layer splint canvas assembly comprises an upper-layer air chute canvas 6, a middle microporous steel plate 7 and a lower-layer air chute canvas 8; the lower layer air chute canvas 8 is detachably fixed on the bottom end surface of the middle microporous steel plate 7 to form a lower layer canvas component, and the upper layer air chute canvas 6 is detachably installed on the top end surface of the middle microporous steel plate 7 and forms a double-layer clamping plate canvas component together with the lower layer canvas component;

go up groove area and lower groove area and utilize double-deck splint canvas subassembly as ventilative layer, the high-pressure air that gets into groove area down gets into groove area on through ventilative layer.

Specifically, the lower layer air chute canvas 8 and the middle microporous steel plate 7, and the middle microporous steel plate 7 and the upper layer chute canvas are fixed by bolts.

This embodiment is on the basis that does not destroy the original exterior structure of air conveying chute 1, does not influence the material and carry the effect, has prolonged the life of air conveying chute canvas, has improved air conveying chute 1's production stability, security, has guaranteed that production is stable, goes on in succession. Compared with the current situation that the canvas of the air chute needs to be replaced 3-5 times per month before modification, the canvas of the air chute can be replaced every 3 months by the application of the embodiment, the replacement frequency of the canvas of the air chute is greatly reduced, and the cost is saved.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
