Description

DEVICE FOR LOADING WELLS

The utility model relates to the field of blasting, namely, devices for the preparation of explosives and loading wells, and can be used in open cast mining for the preparation of industrial, mainly two-component explosives, and at the same time loading wells.

Known charger for wells with bulk explosives, containing a receiving hopper with a net and transfer devices, a metering chamber with a shut-off valve, an air distributor and a transport pipeline (USSR author's certificate No. 340780, class E 21 C 37/00, published in 1972) .

The main disadvantages of the known charger should include its low productivity and the ability to use only pre-prepared explosives, because The functions of the known device are limited only by the supply to the well from the hopper of a certain portion of the finished explosive.

A device for loading wells is known, comprising a receiving hopper with grids and devices for transferring it, divided by partitions into compartments, and a dispenser with a closing valve and combined openings for each compartment equipped with control gates (certificate for utility model No. 8411, class E 21 C 37/00, published in 1998, B. N ° 11).

The known device allows the use of not ready-made explosives for loading wells, but its components, which form an industrial explosive during charging. The device does not have complex metering units and does not require an electromechanical or pneumatic drive, which determines its low cost and reliability.

The disadvantages include the significant cost of manual labor for moving around the charging unit or for loading and unloading operations when using vehicles for this. In addition, after the loading process is completed, a repeated detour of all charged wells is necessary to collect the bulk containers.

a gate valve and calibrated holes for each compartment of the receiving hopper, one of which is made with a constant cross-sectional size, and the rest are equipped with control gates, a guide pipe installed at the outlet of the dispenser, and transfer handles attached to the receiving hopper.

The difference from the known device lies in the fact that it is additionally equipped with devices for hanging on vehicles, placed on the receiving hopper symmetrically about its vertical axis.

Another difference is that the device is equipped with a removable elastic rzgkav installed on the guide pipe.

The above structural differences provide the ability to fix the device, for example, on the lowered side of any means of transport (car, tractor trolley, etc.) and move it between the wells along the rechargeable unit. This embodiment of the device allows to reduce the cost of manual labor for moving it around the block and collecting containers after loading wells.

The essence of the utility model is illustrated by an example implementation for loading a two-component simple explosive. In FIG. 1 shows a general view of a device for loading wells; FIG. 2 is a plan view, in FIG. 3 - node A, section I-I.

The device for loading wells contains a nriemic hopper 1 and a dispenser 2 with a guide pipe 3. The receiving hopper has compartments 4 and 5 for components of explosives, separated by a partition 6 and equipped with supports 7 for installation above the well and handles 8 for carrying the device along the charging unit. Grids or grids 9, 10 are installed in the upper parts of the receiving hopper compartments. The mesh size of the mesh is determined by the type of explosive components that are connected to the receiving hopper. Lattices or grids are intended for sifting the components of explosives and to prevent jamming of the batcher in large pieces. The dispenser 2 is detachably connected to the receiving hopper and is also divided by the continuation of the partition 6 into two compartments. The dispenser is equipped with calibrated holes 11 and 12 located in the lower part. The dimensions of the hole 11 are constant, and the hole 12 is adjustable, for which the dispenser is equipped with an adjusting slide 13c screw 14. The dispenser has a closing valve 15 with a handle 16, with which you can completely block the exit. In this design, the device is used for loading with manual re-transfer between the wells along the chargeable unit. To mechanize the movement of the device can be used various vehicles available in section.

for example, motor vehicles, tractor carts, etc. For this purpose, the device is additionally equipped with devices for mounting it onto vehicles, which may have various designs. For example, such devices can be made in the form of hooks, brackets, pins with nuts, etc. In the given example, devices for hanging on vehicles are made in the form of brackets 17, rigidly connected to the receiving hopper 1, and the brackets are placed symmetrically on its vertical axis AA and equipped with clamping bolts 18 with washers 19. Staples can be installed on one or both longitudinal sides of the receiving hopper. The device operates as follows. For installation on a vehicle, for example, the rear side of the body 20 is lowered on a car and a device for loading wells is hung on it using brackets 17 and fixed with bolts 18, after which the car drives up to the well before installing the guide pipe 3 above it. If it is necessary to close the gap between the well and the guide pipe, the removable elastic sleeve 21 (polyethylene or rubber), the end of which is fixed at the wellhead, is secured with the help of clamps. The device’s presetting is based on simultaneous opening through calibrated openings of both compartments of the hopper of the mass of explosive components, for example grade B granulite. With a closed valve 15, prilled carbamide is poured into compartment 5 of the receiving hopper 1 and granular ammonium nitrate is poured into compartment 4, after which they are fully opened gate valve 15. The components of the explosive in a given ratio come from the departments of the receiving hopper into the guide pipe 3 and then along the elastic sleeve 21 to the well. The preparation of explosives using a device for loading is based on the mixing of components under the action of gravitational forces when granules fall into the well. Due to collisions between the granules, impacts on the walls of the well, turbulent air flows in the well during the passage of granular material, the components of the explosives are evenly distributed over the cross section of the wells, which ensures their uniform mixing. As the components are released from the bunker compartments, they are loaded to the calculated value of the explosive charge. The cessation of the supply of components to the well is carried out by closing the valve 15. After charging, the vehicle with the device moves to another well. In the process of loading the entire unit, the device moves with the help of a car and the container from under the explosive remains in the body, i.e.

manual labor during these operations is practically excluded. Due to the arrangement of the attachment devices symmetrical with respect to the vertical axis, a uniform load is provided on all nodes of the device during movement and loading, and the presence of a removable elastic sleeve reduces the emission of explosive dust particles from the borehole into the atmosphere and reduces the length of the guide pipe for unhindered movement along the charging unit.
