Description

Technical Field

[0001] The invention relates to the technical field of cleaning agent granulation, in particular to a cooling granulation system for special cleaning materials for a screw extruder. Background Art

[0002] In a screw extruder, every time a new batch of products is produced, in order to avoid the previous batch of raw materials affecting the color and properties of the products, it is often necessary to clean out the residual raw materials in the screw extruder. When cleaning the inside of the screw extruder, a corresponding cleaning agent is generally required for auxiliary cleaning. Traditional liquid cleaning agents often have strong acidity and alkalinity, which will not only corrode the screw and inner wall of the screw extruder, but also its residues still need to be carried by resin. At the same time, its cleaning effect is not ideal, and even the device needs to be disassembled for deep cleaning. In contrast, solid cleaning agents containing resins not only have the carrying capacity of resins, but the abrasive inside can make the cleaning ability stronger; and during the production process of solid cleaning agents, screw extruders are generally used to melt and extrude the raw materials, and finally they are produced through cooling and granulation equipment.

[0003] At present, when the existing granulation system granulates the material, it is generally to directly cool and solidify the material extruded by the screw extruder through a water tank, and finally pelletize the material through the shearing component in the granulation system; however, the shearing component and the traction component in the existing granulation system are driven by independent electric drive sources, lack the function of linkage, and the two cannot be effectively coordinated. It is also necessary to additionally set up a control system for controlling the shearing speed of the shearing component and the traction speed of the traction component, thereby increasing the cost of the granulation equipment. Moreover, when the traction component in the existing granulation system is tractioning the material, when the material is at the end of granulation, it is easy for a certain length of material to fail to be pulled to the shearing position, resulting in the problem of residual material. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a cooling and granulating system for special cleaning materials of a screw extruder. The shearing component is connected to the traction component by two third belt groups, so that the shearing component is driven by the traction driving force of the traction component to shear and granulate the special cleaning material. This not only reduces the use of electric drive sources, but also improves the energy saving and environmental protection of the granulating equipment and the orderliness of the traction granulation. Through the setting of the traction component, not only can the cooled special cleaning material be pulled and drawn in an orderly manner, but also the breakage of the special cleaning material caused by excessive traction force can be effectively solved, and the problem of residual material occurring at the end of shearing and granulating the special cleaning material can be avoided.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0045] Embodiment 1:

[0046] See attached Figure 1-11 A cooling and granulating system for special cleaning materials for a screw extruder comprises a base 1, and a cooling component 2 for cooling the special cleaning materials extruded by the screw extruder, a guiding component 3 for guiding the special cleaning materials after cooling, and a granulating mechanism 4 for shearing the special cleaning materials after guiding are arranged on the top of the base 1;

[0047] By setting the cooling component 2, the special cleaning material extruded by the screw extruder can be cooled; by setting the guide component 3, the special cleaning material after cooling can be guided and preliminarily pulled; by setting the granulating mechanism 4, the special cleaning material after cooling and pulling can be sheared and granulated;

[0048] The main components of the special material for cleaning screw extruders are 60% polycarbonate, 39.5% filler, 0.4-0.5% antioxidant, and 0.2-0.3% lubricant. Under the same process, the old product is black and the new product is white. It is found that after cleaning the screw extruder, no black spots can be found on the new product, while obvious black spots can be found after cleaning with traditional cleaning agents.

[0049] The granulating mechanism 4 comprises a shearing assembly 41 for shearing the cooled special cleaning material and a traction assembly 42 for traction the cooled special cleaning material onto the shearing assembly 41, and the shearing assembly 41 is connected to the traction assembly 42 through two third belt groups 7;

[0050] By setting the traction assembly 42, not only can the cooled special cleaning material be pulled and pulled in an orderly manner, but also the problem of the special cleaning material being broken due to excessive traction force can be effectively prevented, and the residual material generated at the end of shearing and granulation of the special cleaning material can be avoided;

[0051] The shearing assembly 41 is connected to the traction assembly 42 by two third belt groups 7, so that the traction driving force of the traction assembly 42 can be used to drive the shearing assembly 41 to shear and granulate the special cleaning material, which not only reduces the use of the electric drive source, but also improves the energy saving and environmental protection of the granulation equipment and the orderliness of the traction granulation.

[0052] The cooling assembly 2 is connected to the guide assembly 3 through two first belt groups 5, and the guide assembly 3 is connected to the granulation mechanism 4 through two second belt groups 6;

[0053] By setting the cooling component 2, the special cleaning material extruded by the screw extruder can be cooled, so as to quickly cool and solidify the extruded special cleaning material, so as to facilitate the subsequent shearing and granulation work.

[0054] See attached Figure 4 and Figure 5 The traction assembly 42 includes a U-shaped frame 421 fixed to the top of the base 1 through a bracket, and two traction members are arranged inside the U-shaped frame 421;

[0055] The two traction members are used to pull and tug the special cleaning material after the guide treatment, so as to facilitate the orderly shearing and granulation work of the shearing component 41;

[0056] The traction member includes two transmission shafts 422 rotatably connected to the inside of the U-shaped frame 421, and the outer surfaces of the two transmission shafts 422 are both transmission-connected to two transmission belts 423, and a plurality of traction blocks 424 are fixedly connected between the two transmission belts 423, and a plurality of arc-shaped slots are opened on the plurality of traction blocks 424;

[0057] By rotating the transmission shaft 422 in the two traction parts, the two sets of transmission belts 423 can be driven to rotate symmetrically, and then the two sets of traction blocks 424 can be driven to rotate. By the rotation of the two sets of traction blocks 424, the cleaning special material after the guide treatment can be driven to pull and traction through a plurality of arc-shaped slots, thereby facilitating the shearing and granulation work of the shearing component 41.

[0058] See attached Figure 4 and Figure 5 Both ends of one of the transmission shafts 422 of the two traction members extend to the outside of the U-shaped frame 421, and both ends of the two transmission shafts 422 are fixedly connected with mutually meshing driving gears 425, and the U-shaped frame 421 is fixedly connected with a motor 426 for rotating and driving one of the transmission shafts 422;

The two transmission shafts 422 are connected by two sets of mutually meshing drive gears 425, so that the two traction parts are synchronously and symmetrically driven to rotate, thereby being able to orderly pull the special cleaning material after the guide treatment.

[0060] See attached Figures 6 to 8 The shearing assembly 41 includes a U-shaped block 411 fixed to one side of a U-shaped frame 421, and a partition plate 412 is fixedly connected to the inside of the U-shaped block 411, and a plurality of through openings are opened inside the partition plate 412, and a U-shaped sliding frame 413 is slidably connected to the inside of the U-shaped block 411, and a shearing block 414 is fixedly connected to the top and bottom of the U-shaped sliding frame 413, and both ends of the U-shaped sliding frame 413 extend to the outside of the U-shaped block 411, and two transmission members 415 for driving the U-shaped sliding frame 413 up and down are arranged on the U-shaped frame 421;

[0061] The transmission member 415 includes two electric telescopic rods for driving the U-shaped sliding frame 413 up and down. The up and down movement of the U-shaped sliding frame 413 can drive the two shear blocks 414 to reciprocate up and down, thereby shearing the special cleaning materials extending through several openings, thereby forming a shearing and granulation work of the special cleaning materials.

[0062] See attached Figure 8 The transmission member 415 includes a movable frame 4151 rotatably connected to the side of the U-shaped frame 421 through a rotating shaft, and the rotating shaft is connected to one of the transmission shafts 422 through a third belt group 7. A protruding rod 4152 is connected to the movable frame 4151, and both ends of the U-shaped sliding frame 413 are provided with movable grooves, and one end of the protruding rod 4152 extends into the inside of the movable groove;

[0063] The movable frame 4151 is rotatably connected to the U-shaped frame 421 by a rotating shaft, and the rotating shaft is connected to one of the transmission shafts 422 through the third belt group 7, so that when one of the transmission shafts 422 rotates, it can synchronously drive the rotating shaft to rotate, and then drive the movable frame 4151 to rotate, and then drive the protruding rod 4152 to move in a circular motion. The circular motion of the protruding rod 4152 can drive the U-shaped sliding frame 413 to reciprocate up and down through the movable groove, forming the reciprocating shearing work of the two groups of shear blocks 414 up and down, with good linkage transmission function, which not only improves the orderliness of the shearing and granulation of special cleaning materials, but also reduces the cost of the granulation equipment and improves the energy-saving and environmental protection performance of the equipment.

[0064] See attached Fig.11 The guide assembly 3 includes a guide frame 31 fixed to the top of the base 1, and the top of the guide frame 31 is rotatably connected to two guide rollers 32, and both ends of the two guide rollers 32 are transmission-connected to any one of the transmission shafts 422 of the two traction members through a second belt group 6;

[0065] The two guide rollers 32 are connected to two symmetrical transmission shafts 422 through two second belt groups 6, so as to drive the two guide rollers 32 to rotate symmetrically. Through the rotation of the two guide rollers 32, the special cleaning material can be guided and preliminarily pulled, thereby improving the convenience of subsequent shearing and granulation.

[0066] Embodiment 2: Based on embodiment 1, the difference is that;

[0067] See attached Figure 8 The movable frame 4151 is internally rotatably connected with a threaded rod 4153, and the outer surface of the threaded rod 4153 is threadedly connected with an adjustment block 4154, and the adjustment block 4154 is slidably connected to the inside of the movable frame 4151, and one end of the protruding rod 4152 is rotatably connected to the outer surface of the adjustment block 4154;

[0068] By driving the threaded rod 4153 to rotate, the position of the adjusting block 4154 can be adjusted, and the position of the convex rod 4152 can be adjusted indirectly, thereby adjusting the diameter of the annular motion track of the convex rod 4152, and adjusting the up and down reciprocating motion distance of the U-shaped sliding frame 413, thereby meeting the shearing granulation work of different sizes of special cleaning material particles, thereby improving the functionality and practicality of the cooling granulation equipment;

[0069] The invention solves the problem that the granulation equipment in the prior art needs to use precise instruments to control and monitor the shear speed in order to meet the granulation work of different particle sizes, resulting in high cost and overly complicated operation.

[0070] Embodiment 3: Based on embodiment 1, the difference is that;

[0072] The U-shaped drain plate 22 is provided to drain the water-cooled special cleaning material, thereby reducing the water on the outer surface of the special cleaning material and improving the dryness of subsequent granulation;

[0073] The U-shaped drain plate 22 is internally rotatably connected with a rotating shaft 23, and the outer surface of the rotating shaft 23 is fixedly connected with a shaking block 24 for shaking and impacting the special cleaning material, and the rotating shaft 23 is transmission-connected to one of the guide rollers 32 through two first belt groups 5;

[0074] The rotating shaft 23 is connected to one of the guide rollers 32 by two first belt groups 5, so that the rotating shaft 23 can be driven to rotate synchronously through the rotation of the guide roller 32, and the rotation of the rotating shaft 23 can drive the shaking block 24 to flip, so that the water-cooled rising special cleaning material can be impacted and shaken, further improving the drainage effect;

[0075] The top of the U-shaped frame 421 is rotatably connected to a rotating shaft 25 through a bracket, and a plurality of fan blades 26 are fixedly connected to the outer surface of the rotating shaft 25. The rotating shaft 25 is transmission-connected to any transmission shaft 422 through a fourth belt set 8.

[0076] The rotating shaft 25 is connected to one of the transmission shafts 422 by two fourth belt groups 8, so that the rotating shaft 25 can be driven to rotate synchronously by the rotation of one of the transmission shafts 422. The rotation of the rotating shaft 25 can drive a plurality of fan blades 26 to rotate, which has a good linkage function and does not require a separate electric drive source to drive, thereby improving the energy-saving and environmental protection performance of the equipment.

[0077] Through the rotation of the plurality of fan blades 26, not only can the water-cooled special cleaning material be air-cooled, but also the water marks on the special cleaning material can be removed by air cooling, thereby improving the effect of subsequent granulation.
