Description

Technical Field

[0001] This utility model belongs to the technical field of sensitive explosives feeding devices, and specifically relates to a special arch-breaking feeding safety device for sensitive explosives. Background Technology

[0002] In the current production process, sensitive explosives are typically pre-placed in a feeding funnel. After personnel leave, the device is activated, and the sensitive explosives are automatically fed. Due to the adhesive properties of the explosives and the influence of moisture, bridging often occurs, where the explosives at the bottom of the funnel are hollowed out, and the upper explosives stop flowing. This necessitates manual entry into the area to clear the bridging using non-igniting tools to facilitate further feeding. Multiple clearing operations are required during a single feeding process, frequently exposing personnel to a hazardous working environment and posing significant safety hazards.

[0003] Therefore, there is an urgent need for a special arch-breaking and feeding safety device for sensitive explosives to solve the problems of poor feeding of sensitive explosives, repeated entry of personnel into dangerous work areas, and significant safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a special arch-breaking and feeding safety device for sensitive explosives, which can solve the safety hazards caused by the current automatic feeding process of sensitive explosives, which requires personnel to enter the dangerous work area multiple times to manually clear the blockage.

[0005] This utility model is achieved using the following technical solution:

[0006] A safety device for breaking the arch and feeding sensitive explosives includes a feeding hopper and a flexible conical feeding device. The flexible conical feeding device is fixedly connected inside the feeding hopper. The upper part of the feeding hopper is a cylindrical barrel, and the lower part is a conical barrel with the smaller opening facing downwards. The diameter of the cylindrical barrel is not greater than the diameter of the larger opening of the conical barrel. A conductive copper rod is connected to the inner wall of the cylindrical barrel, and a conductive wire is connected to the outer wall of the cylindrical barrel. An oscillator is installed on the part of the conical surface of the flexible conical feeding device that protrudes from the smaller opening of the conical barrel.

[0007] When in use, the sensitive explosive is placed in the feeding bucket, and the static-dissipating copper rod is buried at the bottom of the sensitive explosive. The static-dissipating copper rod is used to conduct away the static electricity generated during the feeding process of the sensitive explosive in a timely manner.

[0008] When the oscillator is turned on, the sensitive explosive begins to fall under the influence of gravity. During the fall, static electricity is generated and promptly conducted away through the static electricity conduction wire. Under the action of the oscillator, the soft conical feeding device is squeezed and deformed, which promptly eliminates the bridging phenomenon generated during the process, making the feeding smooth (i.e., achieving arch breaking).

[0009] Preferably, the feeding hopper is made of a non-sparking material and is used to hold sensitive explosives.

[0010] More preferably, an oscillator is installed on the outer wall of the barrel.

[0011] More preferably, four oscillators are evenly distributed in the soft conical feeding device.

[0012] More preferably, the oscillator is driven by compressed air.

[0013] More preferably, the cylindrical barrel and the conical barrel are connected by a flange, and the flexible conical feeding device is installed between the flanges of the cylindrical barrel and the conical barrel. The flange is connected with a jumper wire for conducting static electricity.

[0014] More preferably, the taper of the soft conical feeding device is equal to the taper of the conical barrel, which facilitates a tight fit between the soft conical feeding device and the conical barrel without bulging.

[0015] More preferably, the length of the conical barrel is between 1 / 2 and 2 / 3 of the length of the conical surface of the soft conical feeding device. This is beneficial for the conical barrel to provide support and guidance for the soft conical feeding device, preventing excessive deformation of the soft conical feeding device under the gravity of the sensitive explosive during the feeding process, which would affect the feeding effect.

[0016] More preferably, the taper of the soft conical feeding device is between 45° and 60° with that of the conical barrel, which facilitates the smooth entry of the sensitive explosive from the soft conical feeding device into the reaction vessel under the action of gravity.

[0017] This utility model can automatically unload materials without requiring personnel to enter hazardous work areas. It can automatically clear sensitive explosives, and its structure is reasonable, simple, safe and reliable. It can be widely used in the loading process of sensitive explosives.

[0025] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] A safety device for breaking the arch and feeding sensitive explosives includes a feeding bucket 1 and a flexible conical feeding device 3. The flexible conical feeding device 3 is fixedly connected inside the feeding bucket 1. The upper part of the feeding bucket 1 is a cylindrical bucket 11, and the lower part of the feeding bucket 1 is a conical bucket 12 with the smaller opening facing downwards. The diameter of the cylindrical bucket 11 is not greater than the diameter of the larger opening of the conical bucket 12. A conductive copper rod 5 is connected to the inner wall of the cylindrical bucket 11, and a conductive wire 6 is connected to the outer wall of the cylindrical bucket 11. A vibrator 4 is installed on the part of the conical surface of the flexible conical feeding device 3 that protrudes from the smaller opening of the conical bucket 12.

[0027] The soft conical feeding device 3 and the vibrator 4 can be installed by drilling holes, or the soft conical feeding device 3 can be provided with a vibrator 4 mounting cavity, so that the vibrator 4 can be directly inserted into the soft conical feeding device 3 and closely attached to the conical surface of the soft conical feeding device 3.

[0028] The feeding hopper 1 is made of non-sparking material.

[0029] A vibrator 4 is installed on the outer wall of the cylindrical barrel 11. Four vibrators 4 are evenly distributed on the soft conical feeding device 3. The vibrators 4 are driven by compressed air.

[0030] The flexible conical feeding device 3 can be directly fixed to the top of the cylindrical barrel 11, and then enter from inside the cylindrical barrel 11 and protrude from one end of the small opening of the conical barrel 12. In this embodiment, the cylindrical barrel 11 and the conical barrel 12 are connected by a flange, and the flexible conical feeding device 3 is installed between the flanges of the cylindrical barrel 11 and the conical barrel 12. The flange connection has a jumper wire, which can increase the fit between the flexible conical feeding device 3 and the feeding barrel 1, and the flexible conical feeding device 3 is less likely to bulge during use.

[0031] The taper of the soft conical feeding device 3 is equal to the taper of the conical barrel 12. The length of the conical surface of the conical barrel 12 is between 1 / 2 and 2 / 3 of the length of the conical surface of the soft conical feeding device 3. The taper of the soft conical feeding device 3 and the taper of the conical barrel 12 are between 45° and 60°. The matching and use of the soft conical feeding device 3 and the conical barrel 12 can fix the soft conical feeding device 3 and prevent it from being excessively deformed under the gravity of the sensitive explosive, thus affecting the feeding effect.

[0032] In this embodiment, the feeding hopper 1 is made of stainless steel, and the flexible conical feeding device 3 is made of rubber.

[0033] When feeding the material, start the vibrator 4. The vibrator 4 vibrates and squeezes the soft conical feeding device 3 to break the arch bridge formed by the explosive in time, so as to facilitate feeding.

[0034] Working principle: During use, the sensitive explosive is placed in the stainless steel feeding bucket 1, and the static-dissipating copper rod 5 is buried at the bottom of the sensitive explosive. The vibrator 4 is turned on, and the sensitive explosive begins to fall under the action of gravity. The static electricity generated during the fall of the sensitive explosive is promptly conducted away through the jumper wire and the static-dissipating wire 6. The conical bucket 12 is used in conjunction with the soft feeding device. Under the action of the vibrator 4, the soft feeding device is squeezed and deformed by the vibrator 4, which promptly eliminates the arching phenomenon generated during the process, so that the feeding is smooth.
