Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a separation device for a grinding machine. Background Technology

[0002] After grinding the raw materials for coatings, there is a risk of uneven particle size, which can affect the quality of subsequent coating production. Therefore, a separation device is needed to separate the particles to ensure that the final product has a uniform particle size distribution, thereby improving the quality and performance of the coating.

[0003] In the prior art, Chinese utility model patent application number 202322623024.X discloses a coating raw material grinding machine. The ground powdered coating raw material enters the interior of the screening hood, and the screening hood is vibrated and screened by a vibration motor. The material that meets the specifications is discharged through the screening screen, thus completing the separation. During the screening process, some fine powdered coating will adhere to the screening screen, causing the coating to gradually accumulate and block the screen holes. The screen needs to be manually cleaned by the operator. In the cleaning process, not only will the labor demand increase, but it is also easy to miss some areas, resulting in poor cleaning effect and reduced screening efficiency of the screen, which in turn directly affects the production progress. Utility Model Content

[0004] In view of this, the present invention aims to provide a separation device for a grinding mill to solve the problem of reduced screening efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A separation device for a grinding mill, comprising:

[0007] The box body has an inlet channel at the top, an outlet channel at the bottom, a discharge port on the side wall, and an openable baffle at the discharge port.

[0008] The screening mechanism includes a screening plate disposed inside the box and a vibration mechanism disposed inside the box and connected to the screening plate. The vibration mechanism is used to drive the screening plate to vibrate up and down, and the screening plate and the discharge port are correspondingly arranged in the height direction of the box.

[0009] A sieve plate cleaning mechanism is disposed inside the box and located above the sieve plate. The sieve plate cleaning mechanism has a spray pipe for cleaning the sieve plate.

[0010] Furthermore, the box body is provided with a support plate located below the screening plate, a first guide rod is located at the bottom of the screening plate, and the first guide rod slides on the support plate, and a first elastic element is sleeved on the first guide rod between the screening plate and the support plate.

[0011] Furthermore, the vibration mechanism includes a first drive unit disposed on the housing, a first hinge rod connected to the drive end of the first drive unit, and a second hinge rod with its two ends respectively hinged to the first hinge rod and the screening plate.

[0012] Furthermore, the bottom of the screening plate is provided with a connecting rod arranged along the height direction of the box, and the end of the second hinge rod away from the first hinge rod is hinged to the bottom end of the connecting rod.

[0013] Furthermore, the connecting rod includes a first rod body disposed at the bottom of the screening plate along the height direction of the box body, and a second rod body sliding axially within the first rod body. The second hinged rod is hinged to the bottom end of the second rod body, and a second elastic element is provided between the first rod body and the second rod body.

[0014] Furthermore, the spray pipe extends along the width direction of the box body, and there are multiple spray pipes arranged at intervals along the length direction of the box body; and / or, the spray pipe is provided with multiple nozzles.

[0015] Furthermore, each of the spray pipes is rotatably mounted on the housing via a second rotating shaft.

[0016] Furthermore, each of the second rotating shafts extends through the box body along the width direction and has an extended end located outside the box body; it also includes a swing assembly disposed on the outer side wall of the box body, the swing assembly being tractively connected to each of the extended ends and used to drive each of the spray pipes to swing axially around the corresponding second rotating shaft.

[0017] Furthermore, the swing assembly includes a plurality of sliding seats that can slide on the box body along the length direction of the box body, each sliding seat corresponding to each of the extended ends, and a swing rod is provided between each sliding seat and the corresponding extended end; one end of the swing rod is provided on the corresponding extended end, and the other end of the swing rod is provided with an elongated hole, and a second guide rod is provided on the sliding seat that slides in cooperation with the elongated hole.

[0018] Furthermore, the swing assembly also includes a lead screw threadedly connected to each of the sliding seats, and a second drive unit driven by the lead screw, the lead screw extending along the length of the housing.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] The separation device of the grinding mill described in this utility model can place the raw material to be separated on the screening plate in the box. At this time, the vibration mechanism will drive the screening plate to vibrate up and down, separating the raw material that meets the particle size requirements. The remaining raw material on the screening plate is then cleaned through the discharge port. After screening, the screening plate can be rinsed with cleaning liquid sprayed through the spray pipe to clean the screen holes in the screening plate, prevent the screen holes from being blocked, and ensure the cleanliness of the screening plate and the screening effect.

[0021] Furthermore, the combination of the first guide rod and the support plate ensures stable guidance of the screening plate during vibration. Combined with the first elastic element providing cushioning, it absorbs the impact force generated during vibration, reducing wear and extending the plate's service life. Simultaneously, it allows the screening plate to vibrate more effectively, further reducing material clogging of the screen holes and improving screening efficiency. When the first hinge rod rotates, the second hinge rod can drive the screening plate to vibrate up and down.

[0022] Meanwhile, the first and second rods slide relative to each other under the action of the second elastic element. This second elastic element absorbs the impact and vibration energy generated during the vibration of the screening plate, reducing mechanical stress between the screening plate and connecting components, and lowering wear. This arrangement, with multiple spray pipes spaced apart along the length of the box while extending along the width of the box, ensures that the spray area covers the entire screening plate, further improving the uniformity and coverage of cleaning.

[0023] Furthermore, the spray pipe is rotatably mounted on the housing via a second rotating shaft, allowing the angle of the spray pipe to be adjusted as needed during spraying to ensure effective cleaning of the screening plate. The oscillating assembly drives the spray pipe to oscillate, ensuring wider coverage and improved cleaning uniformity. The screw in the oscillating assembly, in conjunction with the second drive unit, allows for precise control of the spray pipe's oscillation position, further enhancing the cleaning effect on the screening plate.

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] Example 1

[0044] This embodiment relates to a separation device for a grinding mill. In terms of overall structure, as follows... Figures 1 to 6 As shown, it includes a box body 1, a screening mechanism, and a screening plate cleaning mechanism. The top of the box body 1 is provided with a feeding channel 2, the bottom of the box body 1 is provided with a discharging channel 3, and the side wall of the box body 1 is provided with a discharge port 4, and an openable baffle plate 5 is provided at the discharge port 4.

[0045] Furthermore, the screening mechanism includes a screening plate 6 disposed inside the housing 1, and a vibration mechanism 7 disposed inside the housing 1 and connected to the screening plate 6. The vibration mechanism 7 is used to drive the screening plate 6 to vibrate up and down. The screening plate 6 and the discharge port 4 are correspondingly arranged in the height direction of the housing 1. The screening plate cleaning mechanism is disposed inside the housing 1 and located above the screening plate 6. The screening plate cleaning mechanism has a spray pipe 8 for cleaning the screening plate 6.

[0046] At this point, it is understandable that the raw materials entering the box 1 will fall onto the screening plate 6. The screening plate 6 will vibrate under the action of the vibration mechanism 7. Through vibration, the raw materials piled together will be loosened, reducing the adhesion and aggregation between the raw materials, making it easier for the raw materials to move on the screen surface, promoting the uniform spread of the raw materials on the screen surface, ensuring that the entire screen surface is fully utilized, and ensuring the uniformity and efficiency of screening.

[0047] Furthermore, during the vibration of the vibrating mechanism 7, the screening plate 6 vibrates, causing the raw material to continuously jump on the screen surface, reducing the accumulation of raw material in the screen holes and thus reducing screen blockage. After screening, large particles of raw material are cleaned off the screening plate 6 through the discharge port 4, and then cleaning liquid is sprayed out through the spray pipe 8. The cleaning liquid continuously washes the screening plate 6, thereby removing residual raw material in the screen holes, ensuring that the screen holes remain unobstructed, avoiding screen blockage, and guaranteeing the cleanliness of the screening plate 6 and the screening effect.

[0048] Furthermore, while the cleaning liquid sprayed from the spray pipe 8 washes the sieve plate 6, the sieve plate 6 vibrates under the action of the vibration mechanism. The vibration of the sieve plate 6 enhances the interaction between the cleaning liquid and the residual material, thereby improving the cleaning effect.

[0049] In addition, as a preferred embodiment, the discharge port 4 is located on one side of the length direction of the box 1, and the screening plate 6 is gradually inclined upward from the side close to the discharge port 4 to the side away from the discharge port 4. After the raw material passes through the screening, large particles that do not meet the particle size requirements can slide more easily along the inclined screening plate 6 to the discharge port 4, and thus be discharged smoothly without the need for manual cleaning of the raw material on the screening plate 6, reducing manual labor.

[0050] In this embodiment, as a preferred implementation, see [reference needed]. Figure 2 As shown, the housing 1 is provided with a support plate 101 located below the screening plate 6. The first guide rod 102 is located at the bottom of the screening plate 6 and slides on the support plate 101. A first elastic member 103 is sleeved on the first guide rod 102 and located between the screening plate 6 and the support plate 101.

[0051] The design of the first guide rod 102 ensures that the screening plate 6 can only move along the axial direction of the first guide rod 102 when vibrating, reducing unnecessary shaking and improving the controllability of vibration. The first elastic element 103 can provide a buffering effect, reducing the direct impact between the screening plate 6 and the support plate 101 during vibration, thereby reducing mechanical stress and extending the service life of the screening plate 6 and the support plate 101.

[0052] Secondly, in this embodiment, as a preferred implementation, see [reference needed]. Figure 4 As shown, the vibration mechanism 7 includes a first drive unit 701 mounted on the housing 1, a first hinge rod 702 connected to the drive end of the first drive unit 701, and a second hinge rod 703 hinged at both ends to the first hinge rod 702 and the screening plate 6, respectively. This allows the first drive unit 701 to drive the first hinge rod 702 to rotate, thereby transmitting force to the second hinge rod 703, which in turn transmits it to the screening plate 6. This provides stable support for controlling the vibration of the screening plate 6, ensuring the stability and consistency of the screening plate 6 during vibration.

[0053] In this embodiment, as a preferred implementation, see [reference needed]. Figure 4 and Figure 5 As shown, the bottom of the screening plate 6 is provided with a connecting rod 704 arranged along the height direction of the box 1. The end of the second hinge rod 703 away from the first hinge rod 702 is hinged to the bottom end of the connecting rod 704. Furthermore, the connecting rod 704 includes a first rod body 705 disposed at the bottom of the screening plate 6 along the height direction of the box 1, and a second rod body 706 sliding axially within the first rod body 705. The bottom end of the second hinge rod 703 is hinged to the second rod body 706, and a second elastic member 707 is provided between the first rod body 705 and the second rod body 706.

[0054] The design of the connecting rod 704 allows the second rod 706 to slide within the first rod 705. Under the action of the second elastic element 707, the direct impact between the first rod 705 and the second rod 706 can be reduced, thereby reducing wear. Furthermore, as the raw material falls onto the screening plate 6 through the feed channel 2, the screening plate 6 vibrates under the action of the first elastic element and the second elastic element 707. This absorbs the impact energy generated when the raw material falls onto the screening plate 6 and also reduces the impact force on the screening plate 6.

[0055] Furthermore, in this embodiment, as a preferred implementation, see [reference needed]. Figure 3 As shown, the spray pipes 8 extend along the width of the housing 1, and there are multiple spray pipes 8 spaced apart along the length of the housing 1. On the one hand, the spray pipes 8 extend along the width of the housing 1, and on the other hand, multiple spray pipes 8 are spaced apart along the length of the housing 1, which can ensure that the spray covers the entire length of the screening plate 6, further improving the uniformity of cleaning and the coverage area.

[0056] Meanwhile, as a preferred embodiment, the spray pipe 8 in this embodiment is provided with multiple nozzles 801, which can ensure that the spray water flow can cover every corner of the sieve plate 6 and improve the cleaning effect.

[0057] Understandably, the uniform spraying from the spray pipe 8 can promptly remove residual material from the screening plate 6, preventing screen clogging and improving screening efficiency. Specifically, the nozzles 801 on the spray pipe can be cone-shaped nozzles 801 to better remove residual material from the screening plate 6 through stronger impact force.

[0058] In this embodiment, as a preferred implementation, see [reference needed]. Figure 3 As shown, each spray pipe 8 is rotatably mounted on the box body 1 via a second rotating shaft 802, and each second rotating shaft 802 penetrates the box body 1 along the width direction of the box body 1 and has an extended end located outside the box body 1.

[0059] Meanwhile, the separation device of the grinder in this embodiment also includes a swing assembly 9 disposed on the outer side wall of the housing 1. The swing assembly 9 is connected to each extended end in a transmission manner and is used to drive each spray pipe 8 to swing axially around the corresponding second rotating shaft 802. The advantage of this arrangement is that the spray pipe 8 can be adjusted in angle as needed during the spraying process to ensure the cleaning effect on the sieve plate 6.

[0060] In addition, in this embodiment, as a preferred implementation, see [reference needed]. Figure 3 As shown, the swing assembly 9 includes a plurality of sliding seats 901 that can slide along the length of the housing 1 on the housing 1. Each sliding seat 901 corresponds to each extended end, and a swing rod 902 is provided between each sliding seat 901 and the corresponding extended end. One end of the swing rod 902 is provided on the corresponding extended end, and the other end of the swing rod 902 is provided with an elongated hole 903. A second guide rod 904 is provided on the sliding seat 901 and slides in cooperation with the elongated hole 903.

[0061] It is understandable that by sliding the sliding seat 901 along the length of the box 1, and by combining with the sliding seat 901, the spray pipe 8 can dynamically cover different areas of the screen plate 6 during the spraying process. This not only reduces cleaning dead corners and improves the uniformity of spraying, but also allows the position of the spray pipe 8 to be adjusted as needed to adapt to different cleaning requirements.

[0062] In this embodiment, as a preferred implementation, see [reference needed]. Figure 2 As shown, the swing assembly 3 also includes a lead screw 905 threadedly connected to each sliding seat 901, and a second drive unit 906 drivenly connected to the lead screw 905. The lead screw 905 extends along the length direction of the housing 1 so that the sliding seat 901 can move linearly along the length direction of the housing 1 on the lead screw 905 as the lead screw 905 rotates.

[0063] Furthermore, while the sliding seat 901 moves linearly, it can drive the swing rod 902 to swing through the cooperation of the elongated hole 903 and the second guide rod 904, thereby changing the position of the spray pipe 8 and adjusting its position. In addition, the lead screw 905 can achieve precise control of linear motion, allowing the position of the spray pipe 8 to be finely adjusted as needed, making adjustment convenient.

[0064] In this embodiment, as a preferred implementation, see [reference needed]. Figure 6As shown, the separation device of the grinding machine also includes a grinding mechanism 1001 located in the feed channel 2 on the housing 1. Specifically, the grinding mechanism 1001 includes two relatively arranged grinding rollers 1005 for grinding raw materials, each grinding roller 1005 being mounted on the housing 1 via a first rotating shaft 1002. Each first rotating shaft 1002 is equipped with a transmission gear 1003, and the two transmission gears 1003 are meshed together. A third drive unit 1004 is provided on the outer wall of the housing 1, and the third drive unit 1004 is drivenly connected to one of its first rotating shafts 1002.

[0065] Furthermore, the third drive unit 1004 can drive the two grinding rollers 1005 to rotate synchronously through the cooperation of the two transmission gears 1003, thereby achieving uniform grinding of the raw materials. After the raw materials are fed into the feed channel 2, they will first be ground by the two grinding rollers, which greatly reduces the amount of large particles in the raw materials and makes the particle size of the material entering the screening plate 6 more uniform. Secondly, the screening plate 6 can process materials with more uniform particle size more efficiently, reduce the risk of screen hole blockage, and improve screening efficiency.

[0066] In practice, after the raw materials to be separated are placed in the box 1 through the feed channel 2, the raw materials will fall onto the screening plate 6 under their own gravity. At this time, the vibration mechanism 7 will drive the screening plate 6 to vibrate up and down, and separate the raw materials into different particle sizes through the screen holes. Fine powder that meets the particle size requirements falls through the screen holes and is discharged through the discharge channel 3 at the bottom of the box 1, while large particles that do not meet the particle size requirements remain on the screening plate 6.

[0067] After screening is completed, the raw material on the screening plate 6 is cleaned through the discharge port 4, and the large particles are returned to the grinder for further grinding. After cleaning the raw material on the screening plate 6, the cleaning liquid can be sprayed through the spray pipe 8 to rinse the screening plate 6, clean the screen holes in the screening plate 6, prevent the screen holes from being blocked, and ensure the cleanliness and screening effect of the screening plate 6.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
