Description

Technical Field

[0001] This utility model relates to the field of energetic material processing technology, and in particular to a screening device for energetic materials with a spray washing device. Background Technology

[0002] Energetic materials are compounds or mixtures containing explosive groups or oxidizers and combustibles that can independently undergo chemical reactions and output energy. They are an important component of military explosives, propellants, and rocket propellant formulations.

[0003] Energetic materials need to be screened to a suitable particle size when used. However, because their particle size is very small, usually in the micrometer range, the pores of the screen are too fine, which will cause blockage after a period of screening, affecting the efficiency of continuous screening. If the screen is replaced manually every once in a while, the screening process can continue, but it is labor-intensive and increases the risk. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a screening device for energetic materials with a spray washing device, which can realize continuous screening, save manpower, and improve screening efficiency and safety, in order to address the above-mentioned technical deficiencies.

[0005] The technical solution adopted by this utility model is as follows: a screening device for energetic materials with a spray washing device is provided, including a protective box; a mounting frame is provided inside the protective box; the bottom end of the mounting frame is connected to the protective box through multiple shock absorbers; an opening is opened at the top of the protective box; a screening box is provided on the mounting frame; the mounting frame is sleeved on the outside of the screening box; the top end of the screening box extends out from the opening; a feed inlet is connected to the upper side of the screening box, and a discharge outlet is opened at the lower side; a vibrator is fixed on the screening box; and a filter screening assembly is provided on the mounting frame.

[0006] The filtering and screening assembly includes multiple guide rollers rotatably connected to the mounting frame; the multiple guide rollers are all arranged in the front-to-back direction, and one of the guide rollers is driven by a walking motor connected to the mounting frame; the filtering and screening assembly also includes a strip screen without broken ends; the strip screen is circulated and driven by the multiple guide rollers; through openings are respectively opened on the left and right sides of the lower part of the screening box; the upper part of the strip screen passes through the two through openings in sequence along the horizontal direction, and divides the screening box into an upper feeding area and a lower collecting area;

[0007] The screening box is equipped with a rinsing assembly below it; the rinsing assembly includes a collection shell connected to the mounting frame; the collection shell is connected to an external water supply system through a water inlet pipe; multiple nozzles are connected below the collection shell; the nozzles are located inside the strip screen and are used to spray water onto the lower part of the strip screen.

[0008] To further optimize this technical solution, a screening device for energetic materials with a spray washing device has an outlet for impurities at the bottom of the feeding area; both the outlet for impurities and the discharge port are connected to corresponding sealing gates.

[0009] To further optimize this technical solution, the inlet of a screening device for energetic materials with a spray washing device is connected to the screening box via a buffer shock-absorbing sleeve.

[0010] To further optimize this technical solution, a mounting frame for a screening device for energetic materials with a spray washing device is fixed with multiple electric heating modules for heating the lower part of the strip screen.

[0011] The beneficial effects of this utility model are as follows:

[0012] The vibrator can drive the screening box, mounting frame and filter screening components to vibrate together. By adding energetic materials to be screened into the screening box, the belt screen can smoothly screen the energetic materials with the vibration.

[0013] By driving a guide roller with a walking motor, all guide rollers can drive the belt screen in a cyclical transmission, thereby changing the portion of the belt screen entering the screening box. This causes the blocked portion of the belt screen to be removed, while the unblocked portion enters the screening box to continue screening, effectively improving continuous screening efficiency and saving manpower.

[0014] The nozzles can be used to flush and clear blockages from the strip screen, further improving the reliability of continuous screening operations. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-2As shown, a screening device for energetic materials with a spray washing device includes a protective box 1; a mounting frame 2 is provided inside the protective box 1; the bottom end of the mounting frame 2 is connected to the protective box 1 through multiple shock absorbers 3; a passage 4 is opened at the upper end of the protective box 1; a screening box 5 is provided on the mounting frame 2; the mounting frame 2 is sleeved on the outside of the screening box 5; the upper end of the screening box 5 extends out through the passage 4; a feed inlet 6 is connected to the upper side of the screening box 5, and a discharge outlet 7 is opened at the lower side; a vibrator 8 is fixed on the screening box 5; and a filter screening assembly is provided on the mounting frame 2.

[0020] like Figure 1-2 As shown, the filtering and screening assembly includes multiple guide rollers 9 rotatably connected to the mounting frame 2; the multiple guide rollers 9 are all arranged in the front-back direction, and one of the guide rollers 9 is driven by a walking motor 10 connected to the mounting frame 2; the filtering and screening assembly also includes a strip screen 11 without broken ends; the strip screen 11 is circulated and driven by the multiple guide rollers 9; the left and right sides of the lower part of the screening box 5 are respectively opened with through holes 12; the upper part of the strip screen 11 passes through the two through holes 12 in sequence along the horizontal direction, and divides the screening box 5 into an upper feeding area 13 and a lower collecting area 14;

[0021] like Figure 1 As shown, a rinsing assembly is provided below the screening box 5; the rinsing assembly includes a collection shell 15 connected to the mounting frame 2; the collection shell 15 is connected to an external water supply system through a water inlet pipe 16; a plurality of nozzles 17 are connected below the collection shell 15; the nozzles 17 are located inside the strip screen 11 and are used to spray water onto the lower part of the strip screen 11.

[0022] The energetic material powder to be screened is added to the screening box 5 through the feed inlet 6. The powder is then in the feeding zone 13 and supported by the belt screen 11 within the screening box 5. The vibrator 8 is then activated, causing the screening box 5, mounting frame 2, and filter screening components to vibrate together. The powder is then screened by the belt screen 11, and the qualified powder falls into the collection zone 14. Finally, the qualified powder is removed through the discharge port 7. During vibration, the shock absorber 3 effectively reduces the vibration impact transmitted to the protection box 1, improving the overall operational stability of the equipment.

[0023] After screening for a period of time, the strip screen 11 inside the screening box 5 becomes severely clogged. At this time, the walking motor 10 can be started, and the guide roller 9 will drive the strip screen 11 in a circular motion to remove the clogged part from the screening box 5 and move the unclogged part into the screening box 5, so that the screening operation can continue.

[0024] After the blockage is removed, it is moved to a position where it can be sprayed by the nozzle 17 (by controlling the rotation angle of the walking motor 10). Water is supplied to the collecting shell 15 through the external water supply system, and the nozzle 17 sprays water onto the strip screen 11 to clear the blockage. After drying, the strip screen 11 in that area can be used for screening again, improving the reliability of continuous screening.

[0025] like Figure 1-2 As shown, a waste outlet 18 is provided at the lower part of the feed zone 13; both the waste outlet 18 and the discharge outlet 7 are connected to a corresponding sealing door 19. The waste outlet 18 can remove the raw material powder that does not meet the particle size requirements remaining after screening, and the sealing door 19 ensures that the raw material is prevented from leaking out during screening.

[0026] like Figure 1 As shown, the inlet 4 and the screening box 5 are connected by a buffer damping sleeve 20. The ability of the buffer damping sleeve 20 to deform with vibration can ensure a seal at the inlet 4 without affecting the operation of the vibrating screen, thus preventing external debris from getting stuck in the gap between the inlet 4 and the screening box 5 and affecting normal screening.

[0027] like Figure 1 As shown, multiple electric heating modules 21 for heating the lower part of the strip screen 11 are fixed on the mounting frame 2. The electric heating modules 21 (which can be electric heaters, heating wires, heating lamps, etc.) can accelerate the drying of the washing area of ​​the strip screen 11, reducing the time interval between the unblocking parts of the strip screen 11 and its reuse.
