Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of magnetic separator anti-blocking, in particular to an anti-blocking structure of a permanent magnet drum magnetic separator. BACKGROUND

[0002] When the traditional permanent magnet drum magnetic separator works, the materials after magnetic separation slide along the roller skin of the roller to the collecting groove. However, due to the differences in the properties of the materials, such as different particle sizes, different humidities, and different viscosities, part of the materials are prone to stick and accumulate on the vertical plate and the inclined plate of the collecting groove. With the continuous operation of the magnetic separation, the stick and accumulated materials will gradually increase and solidify, forming material clumps or blockages.

[0003] The blockage of materials in the collecting groove will cause a series of serious problems. First, it directly hinders the normal sliding and collection of subsequent materials, resulting in a significant reduction in material collection efficiency, making the magnetic separator unable to operate continuously and efficiently, affecting the continuity and production capacity of the entire production process. Secondly, the blocked materials increase the load of the collecting groove, changing the stress distribution of the collecting groove, which may cause deformation or even damage of the collecting groove in the long run, shortening the service life of the equipment and increasing the cost of equipment maintenance and replacement. Moreover, in order to clean the blocked materials, it is often necessary to stop the machine for manual cleaning, which not only consumes a lot of manpower, material resources and time, but also seriously affects the production progress and reduces the production efficiency of enterprises. In some large-scale continuous production industrial scenarios, this influence is particularly significant.

[0004] The traditional cleaning method is mostly simple manual removal or cleaning with some simple tools, which is difficult to realize automatic and efficient cleaning operation and cannot meet the increasing requirements of modern industry for production efficiency and automation. Therefore, there is an urgent need for an innovative anti-blocking structure that can effectively prevent the blockage of the collecting groove of the permanent magnet drum magnetic separator and automatically and efficiently clean the materials to solve the above problems.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] like Figures 1 to 4 As shown, an anti-clogging structure for a permanent magnet drum magnetic separator includes a base 101. A main shaft 102 and a collection box 105 are mounted on the base 101. A roller 103 is mounted on the main shaft 102, and a collection trough 104 is mounted on the roller 103. An inclined slide groove is provided on the collection trough 104, and an inclined rod 115 is slidably mounted on the inclined slide groove. An inner rod 116 is fixedly mounted on the inclined rod 115, and multiple cleaning plates 117 are fixedly mounted on the inner rod 116. The cleaning plates 117 are slidably connected to the collection trough 104. An upper limit rod 124 is fixedly mounted on the collection trough 104, and an mounting plate 125 is slidably mounted on the slide groove of the upper limit rod 124. Multiple striking blocks 126 are fixedly mounted on the mounting plate 125, and the striking blocks 126 are provided with inwardly recessed rubber material. The shape of the recess is the same as the shape of the corner of the collection trough 104.

[0024] Specifically, the main shaft 102 is driven to rotate by an external motor, the main shaft 102 drives the roller skin on the roller 103 to rotate, and the magnetic separation work is performed. The screened material moves along the outer shape of the roller skin of the roller 103, falls onto the vertical plate and the inclined plate on the left side of the collecting groove 104, and then slides along the vertical plate and the inclined plate and falls into the collecting box 105 below. During use, the material may be adhered and accumulated on the vertical plate and the inclined plate of the collecting groove 104. Therefore, the inclined rod 115 is controlled to slide on the inclined sliding groove of the collecting groove 104, so that the plurality of outer limiting plates 121 driven by the inner rod 116 can scrape the accumulated material on the inclined plate of the collecting groove 104, and the material is moved out of the collecting groove 104 and falls into the collecting box 105.

[0025] It is worth noting that the outer limiting plate 121 is provided with two gentle slopes and steep slopes. The steep slope is located at one end close to the collecting box 105, and the gentle slope is located at one end close to the mounting plate 125. The accumulated material on the inclined plate is scraped by the gentle slope, and the scraped material is pushed by the steep slope. When reset, the material is further pushed by the steep slope to make it separate from the inclined plate, thereby promoting the downward movement of the material.

[0026] As shown in Figure 3 and Figure 4 , the inclined rod 115 is fixedly provided with an outer rod 114, the outer rod 114 is fixedly provided with a middle pushing rod 113, the middle pushing rod 113 is provided with a sliding groove at one end close to the main shaft 102, the middle pushing rod 113 is fixedly provided with an outer limiting plate 121, and the outer limiting plate 121 is slidingly connected to the collecting groove 104.

[0027] Specifically, when the middle pushing rod 113 is pushed, the middle pushing rod 113 drives the outer limiting plate 121 to slide on the collecting groove 104. Because the inclined plate of the collecting groove 104 is inclined, the outer limiting plate 121 is driven to slide horizontally, and then the outer limiting plate 121 drives the middle pushing rod 113 to slide horizontally. At the same time, the outer rod 114 is driven to slide horizontally by the inclined rod 115 sliding on the inclined sliding groove of the collecting groove 104. The inclined sliding groove itself is also inclined with the inclined plate, so that the inclined rod 115 drives the middle pushing rod 113 to slide horizontally through the outer rod 114. Finally, the middle pushing rod 113 drives the middle limiting rod 122 to move when it slides horizontally.

[0028] The distance between the inclined sliding groove of the collecting groove 104 and the inclined plate of the collecting groove 104 still has one end distance, so as to avoid the material on the inclined plate from sliding out through the inclined sliding groove, and the outer rod 114 and the inner rod 116 are arranged in a staggered manner, so that the shape of the inclined rod 115 is inclined from the direction close to the main shaft 102 to the direction close to the inclined plate of the collecting groove 104. Therefore, the material on the inclined plate cannot easily slide out through the inclined sliding groove of the collecting groove 104.

[0029] As shown in Figure 3As shown, the base 101 is rotatably provided with a rotating disc 106 and a driving rod 108, the rotating disc 106 and the driving rod 108 are connected through a ratchet, the driving rod 108 is provided with a convex shaft, the base 101 is fixedly provided with a limiting rod 110, the limiting rod 110 is slidably provided with an L-shaped connecting rod 109, the sliding groove of the L-shaped connecting rod 109 is slidably connected with the convex shaft of the driving rod 108, the collecting groove 104 is fixedly provided with a supporting rod 111, the L-shaped connecting rod 109 is slidably connected with the supporting rod 111, the L-shaped connecting rod 109 is fixedly provided with a control rod 112 at one end close to the intermediate push rod 113, and the control rod 112 is slidably connected with the sliding groove of the intermediate push rod 113.

[0030] Specifically, as shown in the state, Figure 3 When in use, the rotating disc 106 is driven to rotate, the rotating disc 106 drives the driving rod 108 to rotate through the ratchet, the convex shaft of the driving rod 108 drives the L-shaped connecting rod 109 to move upwards, so that the L-shaped connecting rod 109 slides on the limiting rod 110 and the supporting rod 111, the upper end of the L-shaped connecting rod 109 drives the intermediate push rod 113 through the control rod 112, and when the intermediate push rod 113 moves upwards, the intermediate push rod 113 moves transversely through the outer rod 114 and the outer limiting plate 121, so that the control rod 112 slides on the sliding groove of the intermediate push rod 113.

[0031] As shown in the state, Figure 3 and Figure 4 The intermediate push rod 113 is provided with a convex shaft, the collecting groove 104 is fixedly provided with a lower limiting rod 123, the sliding groove of the lower limiting rod 123 is slidably provided with an intermediate limiting rod 122, the middle part of the intermediate limiting rod 122 is provided with a sliding groove, the sliding groove of the intermediate push rod 113 is slidably arranged on the sliding groove of the intermediate limiting rod 122, and the end of the intermediate limiting rod 122 close to the upper limiting rod 124 is slidably arranged on the sliding groove of the upper limiting rod 124.

[0032] The mounting plate 125 is fixedly connected with the intermediate limiting rod 122, and the rotating disc 106 is provided with a chain 107, and the chain 107 is connected with the main shaft 102.

[0033] Specifically, when the intermediate push rod 113 moves transversely, the convex shaft of the intermediate push rod 113 drives the upper end and the lower end of the intermediate limiting rod 122 to slide on the sliding grooves of the upper limiting rod 124 and the lower limiting rod 123 respectively, and when the intermediate push rod 113 moves upwards, the convex shaft of the intermediate push rod 113 slides upwards on the sliding groove in the middle part of the intermediate limiting rod 122. When the intermediate limiting rod 122 moves, the upper end of the intermediate limiting rod 122 drives the mounting plate 125 to move, and the mounting plate 125 drives the knocking block 126 to move transversely away from the intersection of the vertical plate and the inclined plate of the collecting groove 104.

[0034] An assist rod 119 is fixedly installed on the outer rod 114, and a limit block 118 is fixedly installed on the collection groove 104. The assist rod 119 is slidably connected to the limit block 118, and a spring 120 is fixedly installed on the limit block 118. The spring 120 is sleeved on the end of the assist rod 119 away from the outer rod 114, and the assist rod 119 and the spring 120 are fixedly connected.

[0035] Specifically, when the intermediate push rod 113 moves, it drives the outer rod 114 to move. The outer rod 114 pushes the assist rod 119 to slide on the limit block 118, stretching the spring 120. When the turntable 106 drives the drive rod 108 to rotate 180 degrees via the ratchet, the drive rod 108 drives the L-shaped connecting rod 109 to the uppermost position. At this time, the intermediate push rod 113 drives the outer limit plate 121 to move to the upper end of the mouth on the inclined plate of the collection groove 104. The intermediate push rod 113 pushes the intermediate... The limit rod 122 moves the mounting plate 125 to its furthest point, stretching the spring 120 to its maximum length. Then, as the turntable 106 continues to drive, it pushes the drive rod 108, which in turn pushes the L-shaped connecting rod 109 downwards. This causes the intermediate push rod 113 to move downwards. At this point, the spring 120 is no longer stretched. Furthermore, because the drive rod 108 and the turntable 106 are connected by a ratchet, the drive rod 108 can further accelerate its rotation in the direction of rotation of the turntable 106. Figure 3 In the indicated state, when the turntable 106 rotates clockwise, it will push the drive rod 108 to rotate clockwise. However, if the drive rod 108 rotates clockwise at a faster speed than the turntable 106, the drive rod 108 will not be affected by the turntable 106, nor will it affect the turntable 106. Thus, the spring 120 drives the assist rod 119 to accelerate and push the intermediate push rod 113. The intermediate push rod 113 pushes the L-shaped connecting rod 109 through the control rod 112. The L-shaped connecting rod 109 pushes the drive rod 108, and the intermediate push rod 113 drives the intermediate limit rod 122 to reset. The intermediate limit rod 122 pulls the mounting plate 125 to start moving towards the collection tank 104, so that the striking block 126 bridge on the mounting plate 125 receives the junction of the vertical plate and the inclined plate on the collection tank 104 and strikes the vertical plate and the inclined plate, causing the material remaining on the upper part to vibrate and help it slide downward, avoiding further adhesion to the collection tank 104.

[0036] When the intermediate push rod 113 moves downward quickly, the outer limiting plate 121 is also driven to slide downward on the inclined plate of the collecting groove 104, so that the steep slope of the outer limiting plate 121 pushes the scraped material to slide downward, and the material is separated from the inclined plate of the collecting groove 104 through the steep slope, that is, the material is scooped and flies, the friction of other structures of the material is reduced, and the movement of the material is accelerated, so that the material can directly fall into the collecting box 105. The quick downward movement of the outer limiting plate 121 can also avoid that the material scraped by the gentle slope of the outer limiting plate 121 is adhered to the gentle slope due to long-time contact.

[0037] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
