Abstract
The utility model relates to an impurity removing device for explosive charges. The impurity removing device solves the problems that as the traditional explosive charges contain impurities, the potential safety hazard exists and the free-flowing property of the explosive charges is affected. The impurity removing device comprises a support; a dustpan-shaped explosive charge bearing box which is slantwise arranged and is provided with a downward opening is arranged at the front side of the support; a plurality of rows of powerful magnets are fixed in the middle part of the explosive charge bearing box from top to bottom; the distances between the powerful magnets in each row are gradually decreased from top to bottom; a blocking groove plate is fixed on the side wall of the explosive charge bearing box above the powerful magnets, wherein a gap exists between the blocking groove plate and the bottom surface of the explosive charge bearing box; a plurality of elastic static conducting copper bars are fixed at the bottom of the blocking groove plate; and a baffle which can slide up and down is inserted into the blocking groove plate. the impurity removing device is reasonable and reliable in structural design and has the buffer action by controlling the flow velocity of the explosive charges; the filtration effect of the impurity removing device is substantially increased; simultaneously, the potential safety hazard caused by sparks generated due to frictional impact is effectively avoided; the accumulation of static electricity is eliminated; and the impurity removing device has the advantages of being simple in structure, convenient in operation and low in cost.
Description
Technical field
The utility model relates to knot screen, is specially a kind of explosive knot screen.
Background technology
At present, domestic modeling powder explosive production technology mainly is to adopt " aqueous suspension " granulation process, and what drying process adopted is " warm air drying ", in the preparation process, brings irony impurity easily into.Bring into detonator manufacturer, the petroleum perforation charge manufacturer that can directly have influence on use modeling powder explosive of irony impurity presses quick-fried accident because of the friction generates spark in the explosive in the pressing process, all brings tremendous economic loss and potential safety hazard for manufacturer and workman; Contain impurity such as wood chip partly, paper scrap, cotton-wool in the explosive simultaneously, can directly influence the free-running property of explosive.
Summary of the invention
The utility model contains the problem that there is potential safety hazard in impurity and influences explosive fluidity in order to solve in the existing explosive, and a kind of explosive knot screen is provided.
The utility model is to adopt following technical scheme to realize: the explosive knot screen; Comprise support; The front side of support is provided with the beanstalk shaped explosive charge Carrier box of winnowing with a dustpan that inclination is placed and Open Side Down; The middle part of explosive Carrier box is fixing plurality of rows strong magnets from top to bottom, and the spacing between each row's strong magnets reduces from top to bottom gradually, and the explosive Carrier box sidewall of strong magnets top is fixed with the draw-in groove plate that leaves the gap with its bottom surface; The bottom of draw-in groove plate is fixed with plurality of elastic and leads static copper bar, and is inserted with the baffle plate that slides up and down on the draw-in groove plate.
During operation, with pouring the explosive Carrier box into impure explosive, the height through controllable register is the filtering flow velocity of may command explosive; And large granular impurity blocked, the gap that all the other explosives are led between the static copper bar through elasticity flows into, and plays the buffered effect; During through strong magnets, with the irony impurity absorption, strong magnets adopts many rows to be provided with and each row's strong magnets spacing reduces gradually; Can remove the bigger impurity of volume during through first row's strong magnets; During through back row's strong magnets, remove the less impurity of volume, improved adsorption efficiency effectively.
The strong magnets outside surface coats anticollision from inside to outside and leads static layer of cloth and the antifriction static plastic film layers of leading, and prevents that collision produces spark to big mechanical impurity with strong magnets in the downslide process, causes security incident.
The hinged setting in the front side of explosive Carrier box and support, and explosive Carrier box bottom surface outside surface upper articulation has governor lever, the tail rod of placing before and after support is provided with; The other end of governor lever is fixed with the clip that is enclosed within on the tail rod, and is different according to the free-running property of various explosives, unclamps clip; Can realize sliding before and after clip is on tail rod; And then the front and back slip of drive governor lever lower end, thereby the angle of inclination of adjusting explosive Carrier box, the flow velocity of convenient control explosive.
What surface, explosive Carrier box bottom back was connected with ground connection leads the static line, is provided with to lead the generation that the static line is stopped phenomenons such as explosive and explosive Carrier box, baffle plate etc. rub, electrostatic accumulation, has further improved safety performance.
The utility model reasonable in design is reliable; Overcome and brought the problem that impurity is prone to that potential safety hazard takes place and influences explosive fluidity in the existing explosive into; Flow velocity through the control explosive plays shock absorption, and filter effect significantly promotes, and has avoided effectively simultaneously producing the problem that there is potential safety hazard in spark because of collision; Eliminate electrostatic accumulation, had advantage simple in structure, easy to operate and with low cost.
