AI Technical Summary
In urea production plants, loose urea is prone to breaking due to the rapid sliding speed of the chute during transportation, resulting in a decline in product quality.
A cushion device for transporting chutes is designed, including baffle plate, fixing bolt, reinforcement plate and support bolt. Several groups of buffer devices are set along the inclined direction of the chute. The spacing between each group is 1500mm, the angle between the baffle plate and the side wall of the chute is 33°, and the spacing between the baffle plate and the bottom surface of the chute is adjusted through nuts.
By adding a buffer device, the speed of the material in the chute is slowed down, the breakage rate of material particles is reduced, the quality of urea products is improved, and the accumulation of material in the chute is avoided.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of urea production devices, and in particular relates to a bulk urea transport chute buffer device. Background Art
[0002] In a urea production plant, bulk urea needs to be transported to a bulk warehouse or a packaging device through a conveying system. The conveying system includes a conveying belt and a chute. The chute serves as a transition conveying facility between two adjacent belts in the same conveying system. In the prior art, there is a potential difference between the two belts, and the material conveyed by the upper belt slides onto the lower belt through the inclined chute. In order to prevent material accumulation in the chute, the chute has a certain inclination and is very smooth. However, the material particles move at a high speed on the chute, and a small amount of particles will break or crack during the sliding process. After sliding through multiple layers of chutes, the breakage rate of the product particles will increase, and the strength will decrease, affecting the product quality. Utility Model Content
[0003] In order to reduce the breakage rate of bulk urea products during transportation and improve product quality, the utility model provides a bulk urea transportation chute buffer device.
[0004] A buffer device for a bulk urea transport chute, characterized in that: it comprises a baffle, a fixing bolt, a reinforcing plate and a supporting bolt, the baffle is installed 1500mm from the top of the chute, the baffle is symmetrically arranged, one end of the baffle passes through the side of the chute, and the baffle is fixed to the chute with a fixing bolt on the outside, and the fixed position is not less than 20mm from the bottom surface of the chute; the other end of the baffle is inclined downward along the inclined direction of the chute, the installation angle between the baffle and the side wall of the chute is 33°, two symmetrical baffles are connected at the other end, and a triangular reinforcing plate is welded at the connection, a screw hole is opened on the reinforcing plate and a supporting bolt is arranged in the screw hole, two nuts are arranged on the supporting bolt, the two nuts are respectively located on the upper side and the lower side of the reinforcing plate, the bottom of the supporting bolt contacts the bottom surface of the chute, and the distance between the connecting end of the baffle and the bottom surface of the chute is adjusted by the two nuts; a plurality of groups of buffer devices are arranged along the inclined direction of the chute, and the spacing between each group of buffer devices is 1500mm.
[0005] Preferably, the baffle has a width of 20 mm, a thickness of 0.5 mm, and a length = chute width ÷ 2 ÷ cos (33°).
[0006] The beneficial effect of the utility model is that a buffer device is added to the chute to slow down the speed of the material in the chute and reduce the damage of the material particles. After the material stops being transported, the remaining material in the chute will be discharged from the chute normally to avoid material accumulation in the chute. The use of this technology can improve the quality of urea products and reduce the product damage rate by 1%. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Among them: 1-chute, 2-baffle, 3-fixing bolt, 4-support bolt. DETAILED DESCRIPTION
[0010] Embodiment 1: A buffer device for bulk urea transport chute, comprising a baffle 2, a fixing bolt 3, a reinforcing plate and a supporting bolt 4. The baffle 2 is installed 1500mm from the top of the chute 1. The baffle 2 is symmetrically arranged. One end of the baffle 2 passes through the side of the chute 1 and is fixed to the chute 1 with a fixing bolt 3 on the outside, and the fixed position is 20mm away from the bottom surface of the chute 1. The other end of the baffle is tilted downward along the inclination direction of the chute, and the installation angle between the baffle and the side wall of the chute is 33°. Two symmetrical baffles 2 are connected at the other end, and a triangular reinforcing plate is welded at the connection. A screw hole is opened on the reinforcing plate and a supporting bolt 4 is arranged in the screw hole. Two nuts are arranged on the supporting bolt 4, and the two nuts are respectively located on the upper and lower sides of the reinforcing plate. The bottom of the supporting bolt 4 contacts the bottom surface of the chute 1, and the distance between the connecting end of the baffle 2 and the bottom surface of the chute 1 is adjusted by the two nuts. Several groups of buffer devices are arranged along the inclination direction of the chute, and the spacing between each group of buffer devices is 1500mm.
[0011] The baffle 2 is made of 304 stainless steel, with a width of 20 mm and a thickness of 0.5 mm. Its length = chute width ÷ 2 ÷ cos (33°). Since the angle of repose of urea particles is 32°, the baffle 2 is set at an inclination angle of 33° so that product particles will not accumulate. In addition, there is a distance of 20 mm between the baffle and the bottom of the chute. After the conveying is completed, the accumulated granular materials will slip out from this gap, making the buffer device have self-cleaning characteristics.
