Description

Technical Field

[0001] The utility model belongs to the field of petrochemical industry, and specifically relates to "a tangential insertion type wet granulator water gun". Background Art

[0002] At present, the horizontal wet granulator with heating is widely used in the fields of chemical industry, carbon black, fertilizer, electricity, etc. The cylinder of the granulator is divided into: feeding area, granulation area and discharge area; the corresponding stirring shafts are: breaking up the sticky powder in the feeding area, mixing and stirring with granulation water in the granulation area, and outputting particles in the discharge area; the granulation water enters the feeding area and granulation area of ​​the cylinder, the granulation area and the discharge area through the water gun, and its function is to first break up and humidify the dry powder material, then granulate, and granulate the broken particles. The on-site feedback shows that the particle output rate is low, the particle damage and rework rate are high, the granulator capacity fails to meet the process requirements, and the particle quality does not meet the technical indicators. After analysis, it is believed that the main reason is that the water guns at the front end of the granulation area are concentrated on the upper part of the cylinder, the sprayed granulation water covers a small range of powder, and the powder falling under the cylinder cannot contact the water mist, which is one of the reasons why this part of the powder is transported into the granulation area without mixing with the granulation water. Therefore, a technical solution was proposed to change the arrangement and structure of the water gun between the feeding area and the granulation area of ​​the granulator, and a "tangentially inserted wet granulator water gun" was designed. This technology can solve the problem that the powder has been dispersed in the cylinder before entering the granulation area and is fully humidified with the granulation water. After entering the granulation area, it is stirred and granulated, which can greatly improve the particle quality and granulation rate, reduce particle breakage and increase the granulator's production capacity. Summary of the invention

[0003] The utility model aims to design a tangential insertion type wet granulator water gun, including: a water gun assembly, a flange, an indicator plate, a water gun tube, a plugging plate, a barrel, a stirring shaft, a stirring tooth, a water gun seat, a positioning sleeve, a top screw, a gland, a sealing ring, a sealing seat, a connecting pipe, a control valve, and a water inlet pipe. The utility model is characterized in that: the water gun assembly is composed of a flange, an indicator plate, a water gun tube and a plugging plate; the water gun seat is composed of a positioning sleeve, a top screw, a gland, a sealing ring, a sealing seat and a connecting pipe; the barrel is provided with tangential holes for arranging the water gun assembly on both sides near the feed port Toward the mouth; the connecting pipe of the water gun seat is welded on the cutout of the cylinder, and a sealing seat is welded on the connecting pipe; the water gun tube is inserted into the cylinder through the connecting pipe; the sealing ring is installed in the sealing seat, and the sealing ring is compressed by the pressure cover; a flange and an indicator plate indicating the position and direction of the nozzle are welded on the water gun tube, and the bottom is sealed with a blocking plate, and the part extending into the cylinder is longitudinally opened with two rows of parallel nozzles consisting of multiple conical long openings; the middle of the two rows of nozzles faces the direction of the stirring teeth on the stirring shaft; the length of the stirring teeth corresponding to the water gun tube on the stirring shaft is shorter than that of other stirring teeth.

[0004] The design points of this utility model are:

[0005] 1. Reasonably arrange the position and direction of the water gun between the feeding area and the granulation area, and the nozzle is a conical long mouth;

[0006] 2. The water gun tube is equipped with two rows of fan-shaped nozzles, and the water mist spraying area is large to fully contact the powder.

[0007] The beneficial effects of the utility model are:

[0008] 1. The barrel structure and interfaces of the granulator remain unchanged, and the water mist and the material are fully mixed by changing the spray angle and direction of the water gun;

[0009] 2. The powder has been humidified before entering the granulation area, which speeds up the granulation process. The particle surface is smooth, the hardness is high, and the breakage rate is low;

[0010] 3. After entering the granulation area, the granulation water coverage rate reaches more than 90%, the material and granulation water are fully mixed, and the particle qualification rate is high;

[0011] 4. The production capacity of the granulator is increased accordingly, reducing the number of maintenance and repairs. BRIEF DESCRIPTION OF THE DRAWINGS
