Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulverizing equipment technology, specifically a homogenizing pulverizing pump. Background Technology
[0002] The previous crushing pump had an inlet directly inside the feed port, which easily caused uneven feeding. The feed was also slow to reach the next process, and the discharge was uneven, with some material remaining inside the crushing pump. This resulted in low overall crushing efficiency and reduced overall crushing efficiency.
[0003] Document CN 218742240 U discloses a fine grinding pump, including a grinding zone, a bearing housing, a coupling, and a motor. The grinding zone has an outlet at the top and an inlet on one side. The grinding zone includes a housing, a stationary mill, a rotary mill, an adjusting ring, and a three-lobe impeller. A main shaft is housed within the bearing housing. Between the stationary and rotary mills are coarse grinding, medium grinding, and fine grinding zones. The teeth in the coarse grinding zone of the rotary mill include inclined surfaces and flat surfaces; the teeth in the medium grinding zone include inwardly recessed V-grooves; and the teeth in the fine grinding zone include outwardly protruding V-grooves. The coarse grinding zone on the stationary mill has a flat surface 'a' that matches the flat surface of the rotary mill; the medium grinding zone has outwardly protruding V-grooves 'a'; and the fine grinding zone has inwardly recessed V-grooves 'a'. The adjusting ring outside the stationary mill has a telescopic tongue pointing towards the center, which engages with the housing. This structure lacks a conveying structure at the inlet and outlet, easily leading to low efficiency during material entry and exit.
[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention
[0005] To address the aforementioned problems, this utility model discloses a homogenizing pulverizing pump, which inputs, pulverizes, and outputs materials through the pump's inlet and outlet, effectively improving the overall pulverizing efficiency of the materials.
[0006] The technical solution of this utility model is: a homogenizing pulverizing pump, including a motor, a feeding structure, a pulverizing structure and a conveying structure located on the base. The pulverizing structure is located between the feeding structure and the conveying structure. The pulverizing structure includes a three-impeller, a fixed mill and a moving mill. The feeding structure includes a spiral rod located in the feeding chamber. The conveying structure includes a conveying chamber, which includes a small impeller and a large impeller. The outer side of the large impeller is connected to a gasket and a sealing chamber. The upper part of the conveying chamber is the discharge port.
[0007] By adopting the above technical solution, a drive motor is used to drive the rotating shaft to rotate through a coupling. When the material is squeezed into the crushing structure through the screw, it is ground by the fixed mill and the moving mill of the crushing structure. Then, it enters the large impeller through the cyclone force of the conveying structure and exits from the outlet.
[0008] Preferably, the motor output shaft is connected to a rotating shaft via a coupling, and the rotating shaft drives the screw rod, three-impeller, moving mill, stationary mill, small impeller and large impeller.
[0009] By adopting the above technical solution, the motor drives the rotating shaft through the coupling, thereby causing the screw rod, three-impeller, moving mill, stationary mill, small impeller and large impeller to rotate.
[0010] Preferably, the small impeller includes an outer ring plate, an impeller, and an inner ring plate. The impeller is welded to the position between the outer ring plate and the inner ring plate, and a gap is provided between the impellers to allow material to pass through.
[0011] By adopting the above technical solution, after the material is crushed by the crushing structure, the rotation of the small impeller generates a vortex that causes the material to pass through the impeller and enter the large impeller, and then be conveyed out by the large impeller.
[0012] Preferably, the impeller is tilted to one side, and between adjacent impellers, the side of the previous impeller is located inside the side of the next impeller, and the sides of the impellers are stacked one after another. A gap cavity is provided between the stacked parts of the impellers to allow material to pass through.
[0013] By adopting the above technical solution, the small impeller can not only crush and transport the material after it has been crushed by the crushing structure, but also transport the material from the impeller gap of the small impeller to the large impeller, and then transport it out of the outlet through the large impeller.
[0014] Preferably, the large impeller is located on the side of the small impeller away from the feed inlet. The surface of the large impeller is provided with swirling plates that protrude outward from the surface. The swirling plates are circumferentially distributed with the center of the bottom plate as the center. The middle of the swirling plates is provided with circular stiffeners facing the center. Both the swirling plates and the stiffeners face the small impeller.
[0015] By adopting the above technical solution, the large impeller can transfer the material conveyed from the small impeller, so that the material can be transported out of the conveying chamber.
[0016] Preferably, the conveying cavity is convex in shape facing the feed inlet, with a small impeller inside the smaller end of the conveying cavity and a large impeller inside the larger end.
[0017] Preferably, the edges of the small impeller and the large impeller are infinitely close to the conveying chamber, but do not contact each other, and the outlet is located directly above the large impeller.
[0018] By adopting the above technical solution, after the material passes through the small impeller, the rotation of the large impeller transports the material out of the discharge port, thus completing the crushing effect of the material.
[0019] Preferably, the rotation of the screw at the feed inlet drives the material toward the inside.
[0020] By adopting the above technical solution, after the material is fed from the feed inlet, the rotation of the screw will transport the material to the next process.
[0021] The advantages of this utility model are as follows: 1. By setting a screw rod at the feeding end, when the material enters from the feeding port, the material can be fed into the crushing structure through the screw rod, so that the material is transported into the crushing structure evenly and quickly.
[0022] 2. This utility model improves the material transport efficiency of the crushing pump by setting a conveying chamber at the rear of the crushing structure, where the small impeller and large impeller inside the conveying chamber can transport the material upward to the discharge port, and quickly transport the material in the crushing pump out of the discharge port.
[0023] 3. This utility model uses the inlet and outlet of the crushing pump to input, crush, and output materials, effectively improving the overall crushing efficiency of the materials. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0030] like Figure 1-4As shown, the homogenizing pulverizing pump includes a motor 2, a feeding structure, a pulverizing structure, and a conveying structure located on the base 1. The pulverizing structure is located between the feeding structure and the conveying structure. The pulverizing structure includes a three-impeller 6, a fixed mill 8, and a moving mill 7. The feeding structure includes a screw rod 5 located in the feeding chamber 12. The conveying structure includes a conveying chamber 12, which includes a small impeller 9 and a large impeller 11. The outer side of the large impeller 11 is connected to the sealing chamber through a pad 13. The discharge port 14 is located above the conveying chamber 12. The drive motor 2 drives the rotating shaft 10 to rotate through the coupling 3. When the material is squeezed into the pulverizing structure through the screw rod 501, it is ground by the fixed mill 8 and the moving mill 7 of the pulverizing structure. Then, it enters the large impeller 11 through the small impeller by the cyclone force of the conveying structure and exits from the outlet.
[0031] The output shaft of motor 2 is connected to the rotating shaft 10 via coupling 3. The rotating shaft 10 drives the screw rod 501, the three-impeller 6, the moving mill 7, the fixed mill 8, the small impeller 9, and the large impeller 11. Motor 2 drives the rotating shaft 10 via coupling 3, thereby causing the screw rod 501, the three-impeller 6, the moving mill 7, the fixed mill 8, the small impeller 9, and the large impeller 11 to rotate.
[0032] The small impeller 9 includes an outer ring plate 901, an impeller 903, and an inner ring plate 902. The impeller 903 is welded between the outer ring plate 901 and the inner ring plate 902. There is a gap between the impellers 903 to allow the material to pass through. After the material is crushed by the crushing structure, the rotation of the small impeller 9 generates a vortex that causes the material to pass through the gap between the impellers 903 and enter the large impeller 11, and then enter the large impeller 11 and be conveyed out by the large impeller 11.
[0033] Impeller 903 is tilted to one side. Between adjacent impellers 903, the side of the previous impeller 903 is located inside the side of the next impeller 903. The sides of the impellers 903 are stacked one after another. There is a gap cavity between the stacked parts of the impellers 903 for the material to pass through. While the small impeller 9 crushes the material from the crushing structure and conveys it, it can also convey the material from the impeller gap of the small impeller 9 to the large impeller 11, and then convey the material out of the outlet through the large impeller 11.
[0034] The large impeller 11 is located on the side of the small impeller 9 away from the feed inlet 4. The surface of the large impeller 11 is provided with swirling plates 1101 that protrude outward from the surface. The swirling plates 1101 are distributed circumferentially around the center of the bottom plate 1103. The middle of the swirling plate 1101 is provided with a circular rib 1102 facing the center. Both the swirling plate 1101 and the rib 1102 face the small impeller 9. The large impeller 11 can transfer the material conveyed from the small impeller 9, so that the material is transported out from the conveying chamber 12.
[0035] The conveying chamber 12 is convex in shape facing the feed inlet 4. The smaller end of the conveying chamber 12 is equipped with a small impeller 9, and the larger end is equipped with a large impeller 11. The edges of the small impeller 9 and the large impeller 11 are infinitely close to the conveying chamber 12, but do not contact each other. The outlet is located directly above the large impeller 11. After the material in the small impeller 9 passes through, the rotation of the large impeller 11 transports the material out from the discharge outlet 14, thus completing the crushing of the material.
[0036] The rotation of the screw 501 at the feed inlet 4 drives the material toward the inside. After the material is fed into the feed inlet 4, the rotation of the screw 501 transports the material to the next process.
[0037] The material is fed into the feed inlet 4, and then fed into the crushing mechanism through the screw rod 501 in the feed chamber 5. It is coarsely crushed by the three impellers 6, and then finely crushed by the fixed mill 8 and the moving mill 7. The material then passes through the cyclone flow of the small impeller 9 and the large impeller 11 in the conveying chamber 12. The material passes through the gap between the impellers of the small impeller 9, and then is conveyed out from the discharge port under the action of the large impeller 11.
[0038] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
