Abstract

The utility model discloses a bulkhead emptying machine. The problem that the prior art has no ideal blockage dredging effect to a bunker is solved. The bulkhead emptying machine comprises a hydraulic oil cylinder, a piston, a motor, an electromagnetic directional valve, etc. Oil pipes which extend out from the hydraulic oil cylinder are respectively connected with the upper space and the lower space of the piston via the electromagnetic directional valve. The lower end of the piston is connected with a dredging rod. The dredging rod is fixed with multiple groups of blade scrape claws which are arranged at intervals. Two to three blade scrape claws are as one group. The utility model has the advantage of simple structure, easy installation, and high reliability. The interval time of the move of the piston can be arranged in definite time manually via the electromagnetic directional valve. The unique shape of the blade can not block materials and result in the blockage. The resistance force is small when the bulkhead emptying machine moves upwards. The bulkhead emptying machine can pass through a material bed easily, for the convenience of the flow of the materials. The utility model is suitable for the industries of mines, chemical industries, electric forces, etc. The utility model is especially suitable for emptying the blockage in the bunker of the thermal power plant.

Description

The bulkhead cleaner

Affiliated technical field

This practicality newly belongs to the dredger in a kind of solid material course of conveying, belongs to a kind of solid material of clearing up or rather and stops up and to make the unobstructed device of mass transport.

Background technology

At present, in the solid material process of conveying powdered, granular, block or its mixture, reason such as higher or operational throughput is too big owing to humidity, the viscosity of material, make material stick on the bulkhead or be blocked in bunker or container such as awl bucket etc. in, cause cutout, what influence was produced normally carries out, and particularly often takes place when thermal powerplant is carried raw coal.Adopt the method for wall electromagnetic shaker or air bubble to alleviate to a certain extent, unimpeded, but effect is undesirable.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, and a kind of simple in structure, higher bulkhead cleaner of mediation efficient is provided.

The technical solution of the utility model is such: comprise hydraulic ram, piston, electrical motor, solenoid directional control valve etc., the oil pipe that stretches out from hydraulic ram passes through upper space and the lower space that solenoid directional control valve is connected respectively to piston, the lower end of piston connects the mediation bar, and fixing two to three on the mediation bar is one group, spaced how the group blades are scraped pawl.

It is the right-angle triangle that steel plate or iron plate are made that described blade is scraped pawl, and hypotenuse is processed into cutting edge shape.

The utlity model has following beneficial effect:

1, simple in structure, easy for installation, the reliability height is applicable to industries such as mine, chemical industry, electric power, is specially adapted to the block clearing of thermal powerplant coal bunker.

2, to difform bunker container, only need changing blade a little as square awl, circular cone, hyperbola container etc., to scrape the fixed angle of pawl just applicable.

3,, improve user's automatization level and labor efficiency by artificial movement space time of timing setting piston of solenoid directional control valve.

4, blade is scraped pawl and is had than practical characteristics, and cutting edge shape can not result in blockage by the stifled material of canopy, and resistance is less during upward movement, passes the bed of material easily, is convenient to the gravity flow of material, and saving in power.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the perspective view that blade is scraped pawl.

In the accompanying drawings, 1--hydraulic ram 2--solenoid directional control valve 3--electrical motor 4--oil pipe 5--piston 6--mediation bar 7--blade is scraped pawl

The specific embodiment

As shown in Figure 1, electrical motor 3 drives hydraulic ram 1 pressure oil output.The oil pipe 4 that stretches out from hydraulic ram 1 is connected respectively to the upper space and the lower space of piston 5 through solenoid directional control valves 2, and piston 5 connects mediation bar 6 by piston rod, and fixing two to three on mediation bar 6 is that one group many groups of leg-of-mutton blades are scraped pawl 7.

Like this, to piston 5, increase or minimizing drive mediation bar 6 up-and-down movements along with piston 5 tops, lower space oil mass reach the mediation purpose to pressure oil through solenoid directional control valve 3, oil pipe 4.

As shown in Figure 2, it is the right-angle triangle that thick steel plate in 20mm left and right sides or iron plate are made that blade is scraped pawl 7, and hypotenuse is processed into cutting edge shape.It is divided into many groups, and general bigger by the top by following less, determines that according to the volume of bunker blade scrapes concrete group of number of pawl 7, determines that according to the shape of bunker two to three relative blades scrape pawl 7 and be fixed on angle on the mediation bar.

In actual use, piston 5 of the present utility model generally is installed in the outside of bunker, and mediation bar 6, blade are scraped the inside that pawl 7 is installed in bunker, press close to bulkhead.

Claims

1, a kind of bulkhead cleaner, comprise hydraulic ram, piston, electrical motor, solenoid directional control valve etc., it is characterized in that: the oil pipe that stretches out from hydraulic ram passes through upper space and the lower space that solenoid directional control valve is connected respectively to piston, the lower end of piston connects the mediation bar, and fixing two to three on the mediation bar is one group, spaced how the group blades are scraped pawl.

2, bulkhead cleaner as claimed in claim 1 is characterized in that it is the right-angle triangle that steel plate or iron plate are made that described blade is scraped pawl, and hypotenuse is processed into cutting edge shape.
