Description

Technical Field

[0001] This utility model relates to the field of sand making equipment technology, and in particular to a new type of sand making machine impeller. Background Technology

[0002] The impeller of the sand making machine is the core component of the sand making machine. After the material enters the high-speed rotating impeller cavity through the feed port, it impacts the circumferential impact liner at a high speed under the action of centrifugal force, forming a crushing effect. At the same time, collisions and friction between materials are generated.

[0003] Traditional sand making machine impellers have a sand production rate of around 30% during use, short lifespan of wear-resistant impeller parts, and material wear on the impeller body.

[0004] To address this issue, this utility model proposes a novel impeller for a sand making machine. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to propose a novel impeller for a sand making machine to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of this utility model provides a novel sand making machine impeller, including an impeller body. The impeller body includes an upper guard plate and a lower guard plate. A plurality of support plates are arranged between the upper guard plate and the lower guard plate. The plurality of support plates are arranged in an array along the center of the lower guard plate, and an inner cavity channel is formed between the plurality of support plates. A guide plate is installed in each inner cavity channel. An alloy cutter head seat is installed at one end of the support plate, and an alloy cutter head is installed on the alloy cutter head seat. An impact block is installed at the other end of the support plate, and a material distribution pile is installed at the center of the top of the lower guard plate.

[0008] The guide plate is provided with an inclined slope, and the inclination direction of the inclined slope corresponds to the outlet direction of the inner cavity channel.

[0009] The alloy cutter head holder and the alloy cutter head are inclined inwards towards the inside of the blade grinding wheel body.

[0010] The impact block is equipped with a rear baffle at one end near the material distribution pile, and the other end of the rear baffle is connected to the material distribution pile. There are four support plates.

[0011] Both the upper and lower protective plates are equipped with a number of outer protective plates, which are arranged in a circular array along the center of the upper and lower protective plates.

[0012] The top of the upper guard plate has a circular feed inlet, and a protective ring is installed on the outside of the circular feed inlet, which is adapted to the circular feed inlet.

[0013] The bottom of the upper guard plate is provided with four lining plates, which are arranged in an array along the center of the upper guard plate and are adapted to the four internal cavity channels.

[0014] The liner is fixedly connected to the upper guard plate by bolts.

[0015] The guide plate is fixedly connected to the lower guard plate by bolts.

[0016] The four support plates are welded and fixed to the upper and lower guard plates.

[0017] The material distribution pile is fixedly connected to the lower guard plate by bolts.

[0018] The protective ring is fixedly connected to the upper protective plate by bolts.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0020] In this new type of impeller, sand and gravel raw materials enter the interior of the impeller body through a circular feed inlet. When the sand and gravel raw materials collide within the impeller body, they impact the rear baffle. The sand and gravel raw materials are then thrown out of the impeller body through the internal cavity channel by centrifugal force. After being thrown out, the sand and gravel raw materials first come into contact with the alloy cutter head and the impact block. The alloy cutter head can crush the sand and gravel raw materials that are constantly impacting. The sand and gravel raw materials also impact the impact block after being thrown out. The impact block can both crush the sand and gravel raw materials and play a wear-resistant role. By adding a rear baffle and a liner, the life of the impeller wear-resistant parts is improved, the usage cost of the impeller wear-resistant parts is reduced, and the impeller body is protected. By increasing the internal cavity channel of the impeller, the traditional 3 channels are changed to 4 channels, and the sand production rate is increased to about 40%.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0027] like Figures 1 to 3 As shown, a novel sand making machine impeller includes: an impeller body 1, which includes an upper guard plate 7 and a lower guard plate 2. Several support plates 4 are installed between the upper guard plate 7 and the lower guard plate 2. The support plates 4 are arranged in an array along the center of the lower guard plate 2, forming an inner cavity channel 9 between the support plates 4. A guide plate 10 is installed in each inner cavity channel 9. An alloy cutter head seat 5 is installed at one end of the support plate 4, and an alloy cutter head 15 is installed on the alloy cutter head seat 5. An impact block 6 is installed at the other end of the support plate 4. A material distribution pile 8 is installed at the center of the top of the lower guard plate 2. The impact block 6 is an external wear-resistant part of the impeller, used to crush the material in the crushing chamber of the sand making machine. The sand and gravel raw materials are ejected from the inner cavity channel 9, hit the machine guard plate (the guard plate inside the sand making machine cavity), and then return to hit the impact block 6. The impact block 6 crushes the returned material.

[0028] The guide plate 10 is provided with an inclined slope 16, the inclination direction of which corresponds to the outlet direction of the inner cavity channel 9; the inclined slope 16 allows the crushed sand and gravel raw material to be thrown out of the inner cavity channel 9 better, preventing the sand and gravel raw material from clogging, and ensuring that the interior of the impeller body 1 is not blocked and operates stably.

[0029] The alloy cutter head holder 5 and the alloy cutter head 15 are inclined inward to the inside of the vane grinding wheel body 1. The alloy cutter head 15 is inclined inward to the inside of the vane grinding wheel body 1 so that the alloy cutter head 15 can better contact the sand and gravel raw material and crush the sand and gravel raw material.

[0030] The sand and gravel raw material enters the interior of the impeller body 1 through the circular feed inlet 12. The distribution pile 8 allows the sand and gravel raw material to be evenly distributed in each inner cavity channel 9. The impeller body 1 starts to rotate under external drive. The sand and gravel raw material is thrown and impacted by centrifugal force inside the impeller body 1. When the sand and gravel raw material collides in the impeller body 1, it will hit the rear baffle 11. The rear baffle 11 can increase the wear resistance inside the impeller body 1. The sand and gravel raw material is thrown out of the impeller body 1 through the inner cavity channel 9 by centrifugal force. After being thrown out, the sand and gravel raw material first comes into contact with the alloy cutter head 15 and the impact block 6. The guide plate 10 plays a guiding role to prevent the sand and gravel raw material from clogging. The alloy cutter head 15 can crush the sand and gravel raw material that is constantly impacting. The sand and gravel raw material thrown out will also hit the impact block 6. The impact block 6 can both crush the sand and gravel raw material and play a wear-resistant role.

[0031] The impact block 6 is equipped with a rear baffle 11 at one end near the material distribution pile 8. The other end of the rear baffle 11 is connected to the material distribution pile 8. There are four support plates 4, and four internal cavity channels 9 are formed between the four support plates 4. The rear baffle 11 is a wear-resistant steel plate inside the sand making machine cavity, which plays the role of forming a material lining in the sand making machine. Because the sand and gravel raw materials rotate and collide at high speed in the impeller body 1, they will cause wear to the inside of the impeller body 1. The rear baffle 11 can play a wear-resistant role, and can also enhance the support strength inside the impeller body 1 and increase the stability of the internal structure of the impeller body 1.

[0032] Several outer guard plates 3 are installed on both the upper guard plate 7 and the lower guard plate 2. The outer guard plates 3 are arranged in a circular array along the center of the upper guard plate 7 and the lower guard plate 2. The outer guard plates 3 can protect the blade grinding wheel body 1 and prevent it from being worn.

[0033] The top of the upper guard plate 7 has a circular feed port 12. A protective ring 13 is installed on the outside of the circular feed port 12. The protective ring 13 is adapted to the circular feed port 12 and protects the circular feed port 12 from wear.

[0034] The bottom of the upper guard plate 7 is provided with four lining plates 14. The four lining plates 14 are arranged in an array along the center of the upper guard plate 7. The four lining plates 14 are adapted to the four inner cavity channels 9. The lining plates 14 are designed to prevent the sand and gravel materials thrown out at high speed in the inner cavity channels 9 from rubbing against the upper guard plate 7 and the lower guard plate 2, thereby increasing the service life of the upper guard plate 7 and the lower guard plate 2.

[0035] The liner 14 is fixedly connected to the upper guard plate 7 by bolts. The connection between the liner 14 and the upper guard plate 7 by bolts facilitates the installation and disassembly of both, making assembly convenient.

[0036] The deflector plate 10 is fixedly connected to the lower guard plate 2 by bolts, and the connection between the deflector plate 10 and the lower guard plate 2 by bolts facilitates replacement.

[0037] The four support plates 4 are welded and fixed to the upper guard plate 7 and the lower guard plate 2.

[0038] The material stack 8 is fixedly connected to the lower guard plate 2 by bolts.

[0039] The protective ring 13 is fixedly connected to the upper protective plate 7 by bolts.
