Abstract
A pneumatic anti-blocking device for a drum screen comprises a high-pressure air tank, a plurality of pulse air switches which are connected in series through a high-pressure pipe, a common high-pressure pipe, a gas transmission pipe and a plurality of gas injection nozzles; an air pressure source enough for the injection of the air injection nozzle is stored in the high-pressure air tank through the air inlet pipe; a high-pressure pipe arranged at the other end of the high-pressure gas tank is sequentially connected with a plurality of pulse air switches for controlling the blowing on/off and the blowing interval time in series; according to the specific condition of screening materials by the drum screen, setting the blowing on-off time of the pulse air switch and the working interval time of the adjacent pulse air switch; the pulse air switches are sequentially and independently subjected to time-limited blowing within set interval time, and all the pulse air switches are recycled. The high-pressure air flow is delivered into a plurality of air injection nozzles uniformly distributed at the end part of the air injection nozzle through an air delivery pipe to form vertical injection on the screen mesh of the drum screen so as to blow off the blocking materials on the screen mesh of the drum screen. The purpose of cleaning or preventing the screen mesh from being blocked is achieved.
Description
Technical Field
The utility model relates to a clear plug device field of drum sieve screen cloth, concretely relates to utilize compressed air regularly to blow and strike drum sieve screen cloth to realize clearing up or prevent the mesh of screen cloth jam.
Background
The working principle of the drum screen is that a motor drives a speed reducer, a coupling, a drum arranged on a frame and the drum screen to rotate around an axis; when the materials enter the drum screen, sorting the screen holes to realize screening of the materials; the method is widely used for mine, gravel yard, garbage classification treatment and the like. In particular, the garbage classification treatment is free from impurities with high humidity and viscosity due to the complex components of the household garbage. Often causing severe clogging of the trommel; in the prior art, the drum screen is generally knocked manually to enable plugs to fall off, so that the aim of continuing the operation of the drum screen is fulfilled. The defects in the production process are that the labor cost is high, the efficiency is poor, the service life of the drum screen is shortened, and the automatic production of equipment cannot be realized.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a pneumatic anti-clogging device of drum sieve utilizes compressed air regularly to blow and assault the drum sieve screen cloth to realize the purpose of clearance or preventing the screen cloth jam.
The technical scheme of the utility model: the pneumatic anti-blocking device for the drum screen comprises a high-pressure air tank, a plurality of pulse air switches connected in series through a high-pressure pipe, a common high-pressure pipe, a gas transmission pipe and a plurality of gas injection nozzles; the method is characterized in that: one end of the high-pressure gas tank is provided with a gas inlet pipe, the other end of the high-pressure gas tank is provided with a high-pressure pipe, and the high-pressure pipe is connected with a plurality of pulse air switches in series; the connecting pipes at the end parts of the pulse air switches are respectively communicated with a common high-pressure pipe, and one end of the common high-pressure pipe is connected with a gas conveying pipe; the end part of the gas transmission pipe is uniformly provided with a plurality of gas nozzles and is integrally fixed at the top end inside the rotary screen shield; the air outlet of the air injection nozzle is vertically aligned with the screen of the rotary screen.
After the structure is adopted, the air pressure source enough for the air injection nozzle to inject air is stored in the high-pressure air tank through the air inlet pipe arranged at the end part of the high-pressure air tank; a high-pressure pipe arranged at the other end of the high-pressure gas tank is sequentially connected with a plurality of pulse air switches for controlling the blowing on/off and the blowing interval time in series; according to the specific condition of screening materials by the drum screen, setting the blowing on-off time of the pulse air switch and the working interval time of the adjacent pulse air switch; the pulse air switches are sequentially and independently subjected to time-limited blowing within set interval time, and all the pulse air switches are recycled.
The connecting pipes at the end parts of the pulse air switches are respectively communicated with a common high-pressure pipe, and one end of the common high-pressure pipe is connected with a gas conveying pipe; the end part of the gas transmission pipe is uniformly provided with a plurality of gas nozzles and is integrally fixed at the top end inside the rotary screen shield; the air outlet of the air injection nozzle is vertically aligned with the screen of the rotary screen. When the pulse air switch sequentially and independently performs time-limited blowing within set interval time, one shared high-pressure pipe is shared; the high-pressure air flow is delivered into a plurality of air injection nozzles uniformly distributed at the end part of the air injection nozzle through an air delivery pipe to form vertical injection (as shown by arrows in the figure) to the screen mesh of the drum screen so as to blow off the blocking materials on the screen mesh of the drum screen. The purpose of cleaning or preventing the screen mesh from being blocked is achieved.
The utility model has the positive effects that; materials which possibly block the drum screen are blown off in time, so that the blocking of the drum screen is prevented; destructive impact is not generated on the equipment, and the service life of the equipment is prolonged.
Drawings
The attached drawings are schematic diagrams of the specific structure of the utility model; the arrows in the figure indicate the blowing direction of the high-pressure air flow towards the drum screen.
Detailed Description
As shown in the figure, the pneumatic anti-blocking device for the drum screen comprises a high-pressure air tank 2, a plurality of pulse air switches 4 connected in series through a high-pressure pipe 3, a common high-pressure pipe 6, a gas transmission pipe 7 and a plurality of gas injection nozzles 10;
one end of the high-pressure gas tank 2 is provided with a gas inlet pipe 1, the other end is provided with a high-pressure pipe 3, and the high-pressure pipe 3 is connected with a plurality of pulse air switches 4 in series; the connecting pipes 5 at the end parts of the pulse air switches 4 are respectively communicated with a common high-pressure pipe 6, and one end of the common high-pressure pipe 6 is connected with a gas conveying pipe 7; a plurality of air injection nozzles 10 are uniformly distributed at the end part of the air delivery pipe 7 and are integrally fixed at the top end inside the rotary screen shield 8; the air outlet of the air nozzle 10 is vertically aligned with the trommel screen 9.
