Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, and particularly relates to a granulating device for hydrogenated rosin glycerol ester. Background Art

[0002] The production process of hydrogenated rosin glycerol ester generally includes key steps such as esterification reaction, filtration, granulation, metal detection and packaging. In the granulation stage, the molten hydrogenated rosin glycerol ester will drip evenly onto the moving steel belt through the distributor. In this process, the steel belt moves toward the material collection area under the action of the active roller, and the back side is continuously sprayed with cooling water to reduce the temperature of the hydrogenated rosin glycerol ester so that the hydrogenated rosin glycerol ester is cooled into particles. When the steel belt approaches the material collection area, a scraper is set to fit the steel belt to scrape off the hydrogenated rosin glycerol ester particles on the steel belt and guide them into the material collection device.

[0003] However, as the scraper and the steel belt are in contact for a long time, the scraper will wear, which will make it impossible for the scraper to completely remove the hydrogenated rosin glycerol ester particles on the steel belt. At the same time, the flatness error of the steel belt will aggravate this problem. The hydrogenated rosin glycerol ester particles remaining on the steel belt may affect the operation of the next distributor, thereby affecting the production efficiency of hydrogenated rosin glycerol ester.

[0004] Therefore, a kind of hydrogenated rosin glycerol ester granulation equipment is needed. Utility Model Content

[0005] The purpose of the utility model is to provide a hydrogenated rosin glycerol ester granulation equipment, so as to solve the problem that the scraper cannot completely remove the hydrogenated rosin glycerol ester particles on the steel belt due to the wear of the scraper during the granulation of the existing hydrogenated rosin glycerol ester, and the flatness error of the steel belt will aggravate this problem. The specific technical solution is as follows:

[0006] A granulation device for hydrogenated rosin glycerol ester comprises a distributor, a steel belt, an active roller, a driven roller, a frame, a collecting cylinder, a fixed round rod, a cooling mechanism and a scraper, wherein the active roller and the driven roller are respectively installed at both ends of the frame, the steel belt is sleeved on the active roller and the driven roller, the distributor is installed just above the horizontal part of the steel belt and close to one end of the driven roller, the cooling mechanism is installed between the active roller and the driven roller for cooling the steel belt, the collecting cylinder is installed at one end of the steel belt close to the active roller, the fixed round rod is installed in the collecting cylinder, the scraper is rotatably installed on the fixed round rod by a torsion spring, and the end of the scraper away from the fixed round rod is attached to and squeezed with the steel belt under the action of the torsion spring.

[0007] Preferably, the scraper is composed of a plurality of scraper blades, and the scraper blades include a shaft sleeve and a plate. The plurality of shaft sleeves are rotatably mounted on a fixed round rod through a linear array of torsion springs. Elastic retaining rings are installed at both ends of the fixed round rod to position the scraper blades. One end of the plate is tangent to the steel belt, and the other end of the plate is tangent to the shaft sleeve.

[0008] Preferably, a pressure bearing is installed between the sleeves to avoid excessive friction between the sleeves.

[0009] Preferably, a stopper is installed on the side wall of the sleeve, a support rod is installed in a linear array in the collecting tube, a travel switch cooperating with the stopper is installed on the support rod, the support rod and the travel switch are both located directly below the sheet, an alarm is installed on the frame, and the alarm is electrically connected to the travel switch.

[0010] Preferably, the blade plate can cover the shaft sleeve and the stopper, and a spacing of 1-2 mm is provided between the scrapers.

[0011] Preferably, baffles for guiding the movement of materials are installed on both sides of the scraper.

[0012] Compared with the existing technology, the utility model has the following beneficial effects:

[0013] 1. The utility model installs the scraper on the fixed round rod by rotating it through a torsion spring. The torsion spring will make the scraper always rotate in the direction of the steel belt, so the scraper will always fit the steel belt. When the scraper is worn, the scraper will automatically rotate and compensate under the action of the torsion spring to avoid a gap between the scraper and the steel belt, thereby avoiding the residual hydrogenated rosin glycerol ester particles on the steel belt.

[0014] 2. The utility model adopts a plurality of scraper blades to form a scraper, each scraper blade is driven by a torsion spring, and the scrapers can rotate relative to each other. Since there is a certain error in the flatness of the steel belt itself, each scraper blade can adjust itself according to the situation of the steel belt to reduce the possibility of local gaps between the scraper and the steel belt, and further avoid the occurrence of residual hydrogenated rosin glycerol ester particles on the steel belt.

[0015] 3. The utility model installs a travel switch on the collection tube. When the scraper is worn to a certain extent, the block will trigger the travel switch, and the alarm will remind the staff to replace the scraper. At the same time, compared with the integrated scraper, the utility model can replace the scraper with greater wear separately, thereby reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] refer to Figures 1 to 3, the two ends of the fixed round rod 7 are fixedly installed on the inner wall of the collecting cylinder 6 by bolts, and the axis of the fixed round rod 7 is parallel to the axis of the active roller 3. The scraper 10 is rotatably installed on the fixed round rod 7 by a torsion spring. Before the scraper 10 is fitted with the steel belt 2, it is necessary to squeeze the torsion spring to generate a certain pre-pressure. Each scraper 10 is responsible for several rows of hydrogenated rosin glycerol ester particles on the steel belt 2, and scrapers 10 of different widths can be selected according to actual conditions. Pressure bearings are installed between the scrapers 10, which can reduce the friction between the sleeves 102 and facilitate the positioning of the scrapers 10. Each scraper 10 is driven by a torsion spring, and the scrapers 10 can rotate relative to each other. Since there is a certain error in the flatness of the steel belt 2 itself, each scraper 10 can adjust itself according to the situation of the steel belt 2 to reduce the possibility of local gaps between the scraper 9 and the steel belt 2. The scraper blade 10 and the pressure bearing are installed in sequence. When the sleeve 102 and the pressure bearing are tightly fitted, a one-millimeter gap is left between the blades 101 to prevent the scrapers 10 from interfering with each other during rotation. At the same time, this gap will not affect the movement of hydrogenated rosin glycerol ester particles. After the scraper blade 10 is installed, the scraper blade 10 is positioned by elastic retaining rings at both ends of the fixed round rod 7. Baffles 14 for guiding the movement of materials are glued and installed on both sides of the scraper 9 to prevent the particles from falling outside the collection tube 6.

[0024] A plurality of support rods 12 are horizontally installed on the inner wall of the collecting tube 6 by bolts. A travel switch 13 is fixedly installed at one end of the support rod 12 away from the inner wall of the collecting tube 6 by bolts. The support rod 12 and the travel switch 13 are both located below the sheet 101, so the hydrogenated rosin glycerol ester particles will not be disturbed when falling, and the travel switch 13 will not be accidentally touched. A stopper 11 is welded on the side wall of the sleeve 102. When the scraper 10 is worn, the scraper 10 will rotate and compensate under the action of the torsion spring, and the stopper 11 will rotate synchronously. When the scraper 10 is worn to the point where it needs to be replaced, the stopper 11 will rotate to touch the travel switch 13, thereby triggering the travel switch 13. The travel switch 13 will start the alarm installed on the frame 5, and the operator will confirm the scraper 10 that needs to be replaced according to the number of the alarm. Compared with the integrated scraper 9, the utility model can replace the scraper 10 with greater wear separately, thereby reducing maintenance costs. The installation of the distributor 1, the steel belt 2 and the cooling mechanism 8 of the present invention are basically the same as those of the existing steel belt 2 granulator, and will not be described in detail here.

[0025] The pressure pump will press the molten hydrogenated rosin glycerol ester into the distributor 1, and the hydrogenated rosin glycerol ester will be squeezed out from the discharge hole of the distributor 1, and then drip onto the steel belt 2. The steel belt 2 rotates under the joint action of the active roller 3 and the driven roller 4, and drives the hydrogenated rosin glycerol ester to move toward the collecting tube 6. The cooling mechanism 8 will continue to spray cooling water on the back of the steel belt 2 carrying the hydrogenated rosin glycerol ester, thereby cooling the steel belt 2 and the hydrogenated rosin glycerol ester. After the hydrogenated rosin glycerol ester is cooled, hydrogenated rosin glycerol ester particles are formed. After the hydrogenated rosin glycerol ester particles encounter the scraper 9, they will be separated from the steel belt 2 under the action of the scraper 9, and enter the collecting tube 6 under the guidance of the scraper 9 and the baffle 14.

[0026] In summary, the utility model uses the torsion spring to make the scraper 9 realize automatic adjustment compensation, thereby avoiding the gap between the scraper 9 and the steel belt 2, and the residual hydrogenated rosin glycerol ester particles on the steel belt 2, thereby ensuring the stability of the production quality of hydrogenated rosin glycerol ester particles. At the same time, since the partial scraper 10 can be replaced, the maintenance cost is lower than that of the integrated scraper 9.

These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings.
