Description

Technical Field

[0001] The utility model relates to the field of denitration equipment, in particular to a feeding mechanism for urea granule denitration equipment. Background Art

[0002] Urea granule denitrification equipment is a device that uses urea granules as a denitrification reducing agent to perform denitrification operations. When in use, the denitrification agent needs to be stored in a hopper first, and then the urea granules are driven into the device by self-priming by the fan to perform denitrification operations. Since the fan is used to adsorb the urea granules, in order to ensure that the urea granules can pass through the transmission pipeline correctly, it is usually necessary to set a sieve plate in the hopper to screen the urea granules.

[0003] In the prior art, when the sieve plate is in use, small particles can pass through the sieve plate directly, while large particles will stay on the surface of the sieve plate, which will cause the sieve plate's screening efficiency to drop significantly. At this time, it is necessary to manually clean it. During cleaning, the hopper needs to be stopped, which will cause feeding interruption. The entire device is inconvenient to use. Therefore, a feeding mechanism for urea granular denitrification equipment is proposed to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The feeding assembly 2 includes a lower hopper 29 for connecting to a suction fan, and the suction fan is a prior art and can drive the urea granules in the lower hopper 29 into the denitrification device by adsorption. Due to the prior art and the fact that it can be implemented by personnel in this field, this case will not be described in detail. The lower hopper 29 is fixedly connected to the bottom end of the storage box 1, and the inner wall of the storage box 1 is fixedly connected with a guide plate 21 for guiding the urea granules to fall to the middle position of the sieve plate 22, and the number is Multiple groups, the inner wall of the storage box 1 is fixedly connected to the upper part near the lower hopper 29 with a fixed sleeve 24 for supporting the movement of the slide bar 25, the inner wall of the fixed sleeve 24 is slidably connected to the slide bar 25 for supporting the movement of the screen plate 22, the outer wall of the slide bar 25 is fixedly connected to a support ring 26 for supporting the bottom end of the screen plate 22, the outer wall of the slide bar 25 is sleeved with a screen plate 22 for screening urea particles, and the top of the slide bar 25 is threadedly connected to a fixed cap 27 for blocking the top of the screen plate 22. The bottom end of the rod 25 is fixedly connected with a return spring 28 for supporting the slide rod 25. The bottom end of the return spring 28 is fixedly connected to the inner wall of the fixed sleeve 24. The return spring 28 will support the slide rod 25 upward to prevent the sieve plate 22 from moving downward excessively. The left end of the storage box 1 is provided with a discharge trough 23 for discharging large particles. The middle of the sieve plate 22 is raised, and small particles will directly pass through the sieve plate 22, while large particles will escape from the storage box 1 from the discharge troughs 23 on both sides along the inclined surface of the top of the sieve plate 22.

[0031] Reference Figure 2 - Figure 4 The vibration assembly 3 includes a rotating shaft 32 for supporting the cam 33. The rotating shaft 32 is rotatably connected to the inner wall of the storage box 1. The outer wall of the rotating shaft 32 is fixedly connected to the cam 33 for driving the sieve plate 22 to vibrate up and down. The front end of the storage box 1 is equipped with a motor 31 for driving the rotating shaft 32 to rotate. The rear end of the output shaft of the motor 31 is fixedly connected to the front end of the rotating shaft 32. Starting the motor 31 can drive the rotating shaft 32 to rotate, and the rotation of the rotating shaft 32 can drive the cam 33 to rotate. When the sieve plate 22 contacts the cam 33, the rotation of the cam 33 can drive the sieve plate 22 to vibrate up and down. The collecting assembly 5 includes a fixing frame 51 for supporting the collecting box 52. The bottom end of the fixing frame 51 is plugged with a collecting box 52 for collecting large particles.

[0032] Reference Figure 2 - Figure 4The front end of the collection box 52 passes through and is slidably connected with a block 53 for fixing the collection box 52. The inner wall of the fixing frame 51 is provided with a slot 55 for accommodating the block 53. The block 53 and the slot 55 are adapted. When the block 53 is inserted into the slot 55, the collection box 52 will be fixed and cannot move downward from the inside of the fixing frame 51. The rear end of the block 53 is fixedly connected with a fixing spring 54 for supporting the block 53. The rear end of the fixing spring 54 is fixedly connected to the inner wall of the collection box 52. The fixing spring 54 will always push the block 53 outward to prevent it from escaping from the inside of the slot 55 at will. The shielding assembly 4 includes a support sleeve 41 for supporting the sliding of the shielding plate 43. The right end of the support sleeve 41 is fixedly connected to the left end of the storage box 1. The inner wall of the support sleeve 41 is slidably connected with a shielding plate 43 for shielding the discharge trough 23. The top of the shielding plate 43 is fixedly connected with a shielding spring 42 for pushing the shielding plate 43. The top of the shielding spring 42 is fixedly connected to the inner wall of the support sleeve 41.

[0033] The discharge chute 23 can be cleaned up, and the large particles leaving the storage box 1 will fall into the interior of the collection box 52 under the action of gravity.

[0034] When it is necessary to clean the particles inside the collection box 52, the two sets of blocks 53 can be moved to disengage them from the inside of the slot 55 at the same time, and then the collection box 52 can be moved downward to separate it from the fixing frame 51. As the collection box 52 moves downward, the baffle plate 43 is no longer squeezed upward, so the baffle spring 42 can push the baffle plate 43 to move downward to close the left end of the discharge trough 23, thereby preventing large particles from falling out from this side. After the collection box 52 is removed, the large particles inside it can be cleaned.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
