Description

Technical Field

[0001] The utility model relates to the field of urea production cooling equipment, in particular to urea production cooling equipment. Background Art

[0002] Urea, also known as carbamide, has the chemical formula CH4N2O or CO(NH2)2. It is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal and one of the simplest organic compounds. It is the main nitrogen-containing end product of protein metabolism and decomposition in mammals and some fish. Urea needs to be cooled after production to facilitate subsequent bagging, so cooling equipment is needed.

[0003] At present, when cooling urea, most of the existing methods are to directly spread the urea on a drying board for cooling. In this way, the waste is not broken up during cooling, which is prone to nodules, thereby reducing the cooling rate of the waste. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a urea production cooling device to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model proposes a urea production cooling device, comprising a cooling box, a feed hopper is provided on the top of the cooling box, a sealing plate is slidably connected to the top of the feed hopper, a fan is provided on one side of the cooling box, a discharge chute is provided at the bottom of the cooling box, and a support leg is fixedly installed at the bottom of the cooling box;

[0006] A crushing mechanism is provided inside the feed hopper, and the crushing mechanism includes a motor, a rotating shaft, a fixed ring and a crushing plate. A motor is fixedly installed on one side of the feed hopper, and a rotating shaft that penetrates and extends into the feed hopper is fixedly installed on the output shaft of the motor. A fixing ring is fixedly installed on one end of the rotating shaft located in the feed hopper, and a crushing plate is fixedly installed on the outer ring of the fixing ring. The crushing plate is used to crush urea when cooling it.

[0007] In one example, a first inclined plate and a second inclined plate are fixedly mounted on both sides of the inner wall of the cooling box.

[0008] In one example, a groove is opened on one side of the inner wall of the cooling box, and an electric push rod is fixedly installed on the inner wall of the groove.

[0009] In one example, a connecting block is fixedly mounted on the output shaft of the electric push rod, and the connecting block is slidably connected to the groove.

[0010] In one example, a trapezoidal block is fixedly mounted on one side of the connection block, and the trapezoidal block is respectively connected with the first inclined plate and the second inclined plate.

[0011] In one example, a material discharge chute plate is fixedly mounted on one side of the inner wall of the cooling box, and the material discharge chute plate matches the material discharge chute.

[0012] The urea production cooling equipment proposed by the utility model can bring the following beneficial effects:

[0013] 1. The urea production cooling equipment can drive the rotating shaft to rotate by starting the motor, and drive the breaking plate to rotate by the fixed ring, so that large pieces of urea can be broken up. The broken urea is transported to the first inclined plate and the second inclined plate through the feed hopper for drying and cooling, so that the urea particles are not too large to be cooled, so that they can be broken up and a better drying and cooling effect can be achieved.

[0014] The urea production cooling equipment can drive the connecting block to move by starting the electric push rod, and can drive the trapezoidal block to move, and knock and vibrate the first inclined plate and the second inclined plate to prevent urea residue from sticking to their surfaces, so that they can be knocked and vibrated, thereby making the surfaces of the first inclined plate and the second inclined plate cleaner after drying.
