Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and specifically to a pressure-boosting grinding device that facilitates impeller replacement. Background Technology

[0002] A grinding disc is a carrier for applying or embedding abrasive grains, enabling the abrasive grains to perform cutting action, and also serves as a shaping tool for the ground surface. An integrated grinding disc is a grinding tool with a one-piece design, typically used for surface treatment and polishing of materials such as metal, stone, and concrete. However, in actual production and processing, existing integrated grinding discs have the following drawbacks:

[0003] 1. If the impeller is damaged during use, it cannot be replaced separately; the entire integrated grinding disc must be replaced, which increases the cost of use.

[0004] 2. The integrated grinding disc is machined in one piece. Due to the small machining surface of the impeller, the flow rate and outlet pressure are relatively small during the machining process. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a pressure-boosting grinding device that facilitates impeller replacement. This solves the problem that when the impeller is damaged during use, it cannot be replaced individually, and the entire integrated grinding disc must be replaced, which increases the cost of use. Additionally, the impeller has low flow rate and outlet pressure during processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pressure-boosting grinding device for easy impeller replacement includes a stator grinding disc and a rotor grinding disc. A fixed main shaft is provided on one side of the rotor grinding disc, and a limiting groove is provided on the other side of the rotor grinding disc. A rotor boosting impeller is detachably provided in the limiting groove. The rotor boosting impeller has multiple first connecting holes for connecting bolts to be inserted. An impeller fixing plate is provided on the side of the rotor boosting impeller away from the rotor grinding disc. A first fixing hole for fixing bolts to be inserted is provided through the impeller fixing plate.

[0008] As a preferred technical solution of this utility model, the rotor grinding disc is provided with a second connecting hole that is connected to the first connecting hole.

[0009] The above technical solution utilizes the first and second connecting holes and the connecting bolts to facilitate the replacement and disassembly of the rotor booster impeller by the staff.

[0010] As a preferred embodiment of this utility model, the fixed spindle is provided with a second fixing hole that communicates with the first fixing hole.

[0011] As a preferred technical solution of this utility model, the rotor grinding disc in the limiting groove is provided with multiple positioning grooves, and the rotor booster impeller is provided with a positioning rod that can be engaged with the positioning groove.

[0012] Through the above technical solution, by using the positioning rod and positioning groove, the first connecting hole and the second connecting hole in the rotor booster impeller that is locked in the limiting groove are connected one by one.

[0013] As a preferred technical solution of this utility model, the stator grinding disc is provided with an impeller receiving groove on the side near the rotor grinding disc, which can accommodate the rotor booster impeller.

[0014] As a preferred technical solution of this utility model, the stator grinding disc is provided with a pressure plate receiving groove that can accommodate the impeller fixing pressure plate, and the pressure plate receiving groove is connected to the impeller receiving groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a detachable rotor booster impeller design, allowing for individual replacement of the impeller and reducing maintenance costs. Furthermore, the detachable impeller is an independently machined part with a large machining area, resulting in a larger contact surface with the material. This avoids the limitations of one-piece machining, which leads to a smaller machining area and consequently, lower outlet pressure and flow rate in later production processes.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Example

[0023] This utility model provides a pressure-boosting grinding device that facilitates impeller replacement, see reference. Figure 1-2 As shown, the device includes a stator grinding disc 1 and a rotor grinding disc 2, with the gap between the stator grinding disc 1 and the rotor grinding disc 2 forming a grinding zone. This invention utilizes a detachable rotor booster impeller 3, allowing for individual replacement and reducing maintenance costs. Furthermore, the detachable rotor booster impeller 3 is an independently machined part with a large machining area, resulting in a larger contact surface with the material. This avoids the limitations of integrated machining, which leads to a smaller machining area and consequently, lower outlet pressure and flow rate in later production processes.

[0024] The stator grinding disc 1 has an impeller receiving groove 8 on the side near the rotor grinding disc 2, which can accommodate the rotor booster impeller 3. The stator grinding disc 1 has a pressure plate receiving groove 9 that can accommodate the impeller fixing pressure plate 6. The pressure plate receiving groove 9 is connected to the impeller receiving groove 8. Through the matching of the impeller receiving groove 8 and the pressure plate receiving groove 9, the distance between the stator grinding disc 1 and the rotor grinding disc 2 can be adjusted by the operator without affecting the operator's ability to adjust the distance between the stator grinding disc 1 and the rotor grinding disc 2.

[0025] One side of the rotor grinding disc 2 is provided with a fixed main shaft 5, and the other side of the rotor grinding disc 2 is provided with a limiting groove 14. The limiting groove 14 facilitates the installation of the rotor booster impeller 3 on the rotor grinding disc 2. The rotor booster impeller 3 is detachably installed in the limiting groove 14. The detachable design of the rotor booster impeller 3 allows for individual replacement of the rotor booster impeller 3, reducing maintenance costs. The rotor booster impeller 3 has multiple first connecting holes 10 for connecting bolts 4 to be inserted. The side of the rotor booster impeller 3 away from the rotor grinding disc 2 is provided with an impeller fixing plate 6. The impeller fixing plate 6 improves the tightness of the rotor booster impeller 3 installed on the rotor grinding disc 2. The impeller fixing plate 6 has a through first fixing hole for fixing bolts 7 to be inserted. The fixing bolts 7 are fitted with flat washers and anti-loosening washers, which improves the stability of the fixing bolts 7 inserted into the first fixing hole and the second fixing hole 15.

[0026] The rotor grinding disc 2 has a second connecting hole 11 that communicates with the first connecting hole 10. The second connecting hole 11 is a countersunk hole. The connection bolt 4 is installed through the first connecting hole 10 and the second connecting hole 11 to facilitate the replacement and disassembly of the rotor booster impeller 3 by the operator.

[0027] The fixed spindle 5 has a second fixed hole 15 that communicates with the first fixed hole. The first fixed hole and the second fixed hole 15, together with the fixing bolt 7, can fix the impeller fixing plate 6, and further improve the tightness of the rotor booster impeller 3 on the rotor grinding disc 2.

[0028] The rotor grinding disc 2 within the limiting groove 14 has multiple positioning slots 13, with at least two positioning slots 13. The rotor booster impeller 3 is equipped with positioning rods 12 that can engage with the positioning slots 13. The positioning rods 12 and positioning slots 13 ensure that the first connecting hole 10 and the second connecting hole 11 in the rotor booster impeller 3, which is engaged within the limiting groove 14, are connected one-to-one, thus improving the installation efficiency of the rotor booster impeller 3 on the rotor grinding disc 2.

[0029] The working principle of this utility model is as follows:

[0030] When the rotor booster impeller 3 is damaged, first remove the fixing bolts 7 inserted in the first fixing hole and the second fixing hole 15, thereby removing the impeller fixing plate 6. Then remove the connecting bolts 4 inserted in the first connecting hole 10 and the second connecting hole 11, and the rotor booster impeller 3 can be removed from the rotor grinding disc 2.

[0031] Align the positioning rod 12 on the new rotor booster impeller 3 with the positioning groove 13 on the rotor grinding disc 2 and insert it so that the rotor booster impeller 3 is engaged in the limiting groove 14. At this time, the first connecting hole 10 on the rotor booster impeller 3 and the second connecting hole 11 on the rotor grinding disc 2 are connected. Insert the connecting bolt 4 into the connected first connecting hole 10 and second connecting hole 11 for fixing, thereby installing the rotor booster impeller 3 in the limiting groove 14. Then, install the impeller fixing plate 6 from the outside of the rotor booster impeller 3 so that the first fixing hole on the impeller fixing plate 6 is connected with the second fixing hole 15 in the fixing main shaft 5. Insert the fixing bolt 7 into the first fixing hole and the second fixing hole 15 for fixing, thereby pressing and fixing the rotor booster impeller 3 in the limiting groove 14, thus completing the installation of the rotor booster impeller 3.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
