Description

Technical Field

[0001] The present application relates to the technical field of material screening, and specifically discloses an automatic sorting device for crusher material particles. Background Art

[0002] The calcium hydroxide production process is composed of a raw material crushing system, a raw material storage system, and a multi-stage raw material digestion system. The raw materials pass through the above systems in sequence to prepare the finished calcium hydroxide product.

[0003] The raw material crushing system consists of a crusher, a crusher feeding device installed above the crusher for delivering raw materials, and a feeding device installed below the crusher for sending out the crushed materials. In the prior art, jaw crushers are often used to crush raw materials into material particles of different particle sizes.

[0004] The particle size of the material obtained by the traditional jaw crusher is roughly uniform, and the raw materials can be finely crushed. However, during the continuous operation, there may still be incompletely crushed materials, and the material particles are larger than the required particle size. Therefore, a sorting device is often installed between the discharge port of the crusher and the feeding device to sort the material particles larger than the required particle size and discharge them. However, most of the sorting devices in the prior art use a screen plate, and a frame is used to install one or more inclined screen plates, and a spring mechanism is installed between the frame and the screen plate to enable the screen plate to have the function of shaking up and down. The screen plate is hit by a hammer to make it shake up and down. In the process of shaking up and down, the material particles with too large particle size are screened out and discharged from the end of the screen plate, and the material particles with composite particle size pass through the screen plate and are discharged from the bottom of the screen plate into the feeding device.

[0005] When the sieve plate shakes up and down, the material particles will collide with the grid on the sieve plate during the shaking process, which may hit the material particles and make them fly out. There is also a situation where the material particles that meet the particle size are hit and discharged directly from the end of the sieve plate.

[0006] Therefore, in view of this, the inventor provides an automatic sorting device for crusher material particles to solve the above problems. Utility Model Content

[0007] The utility model aims to solve the problem that in a traditional material particle sorting device, the inner screen plate is installed obliquely and has the function of shaking up and down to achieve material sorting, and some material particles will be hit and fly out directly during the up and down shaking sorting process.

[0008] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides an automatic sorting device for crusher material particles, including a sorting box, sorting shafts rotatably connected to the two ends of the sorting box, and a driving motor fixed to the sorting box and used to drive the sorting shaft at one end to rotate, the sorting shafts are all connected with sorting rollers in an axial sliding manner, and a sorting belt is meshed between the sorting rollers at both ends. The sorting belt is provided with a number of dropping troughs for compliant material particles to fall down, and the inner sides of the sorting box are provided with corner baffles that fit the end surfaces of the two sides of the sorting belt. The corner baffles on both sides are fixed with a pushing structure that can reciprocate and alternately abut against the end of the sorting roller and make the sorting roller slide to the other end. The sorting box between the corner baffles on both sides is provided with a feed inlet at one end and a large particle material outlet at the other end. One side of the sorting box is provided with a qualified material outlet, and the sorting box is provided with a transfer plate that is connected to the qualified material outlet and extends obliquely between the upper and lower sides of the sorting belt.

[0009] Furthermore, the sorting belt is provided with connecting parts on both sides thereof which fit in with the inner side of the corner baffle, and the material dropping chute is provided on the sorting belt between the connecting parts on both sides.

[0010] Furthermore, the blanking trough is specifically a blanking ring groove opened on the sorting belt and closed at both ends, a plurality of connecting plates are fixedly connected between the connecting parts on both sides at equal distances, and the sorting belts between adjacent blanking ring grooves are fixedly connected to the inner side of the connecting plates.

[0011] Furthermore, the connecting plates are all inclined toward the large particle material outlet, and a receiving chamber for receiving and separating the material particles is formed between adjacent connecting plates.

[0012] Furthermore, the pushing structure includes a butt plate fixedly connected to the inner side of the corner baffle, and both ends of the sorting drum are staggeredly fixedly connected with butt platforms that can be pushed inward by the butt plate.

[0013] Furthermore, a vibration mechanism for supporting the material transfer plate is provided in the sorting box below the material transfer plate, and a striking block for striking the material transfer plate is fixedly connected to the end of the sorting roller.

[0014] The principle and effect of this scheme are:

[0015] 1. Compared with the prior art, the utility model has a sorting belt installed in the sorting box, and the sorting roller is driven by the sorting shaft, which in turn drives the sorting belt to rotate. A drop trough is provided on the sorting belt for sorting qualified material particles and discharging them through a delivery plate, while unqualified material particles remain on the sorting belt and are driven to the large particle material outlet for discharge as the sorting belt rotates, thereby realizing automatic sorting of material particles crushed by a crusher.

[0016] 2. Compared with the prior art, the sorting roller installed in the sorting box of the utility model is installed on the sorting shaft in a sliding connection manner, and a pushing structure is installed on the inner side of the corner baffle of the sorting box to push the sorting roller to slide synchronously along the axial direction on the sorting shaft, so that the sorting roller and the sorting belt between the sorting rollers have the function of shaking left and right, and then shake the material particles accumulated on the sorting belt between the corner baffles on both sides left and right, and screen the material particles that meet the particle size through the drop chute on the sorting belt, which solves the problem of traditional material particle sorting devices, in which the inner screen plate is installed obliquely and has the function of shaking up and down to realize material sorting, and some material particles will be hit and fly out directly during the up and down shaking sorting process.

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] The figure marks in the drawings of the specification include: sorting box 1, feed hopper 2, active sorting shaft 3, driven sorting shaft 4, transfer plate 5, corner baffle 6, sorting belt 7, drop chute 8, connecting plate 9, sorting roller 10, sleeve 11, abutment plate 12, abutment platform 13, striking block 14, slider 15, slide chute 16.

[0024] A crusher material particle automatic sorting device, for example Figure 1 As shown:

[0025] It includes a sorting box 1, a rotatable sorting shaft installed at both ends of the sorting box 1, and a driving motor installed on the sorting box 1 and used to drive the sorting shaft at one end to rotate. In this embodiment, the sorting shaft directly driven by the driving motor is named as the active sorting shaft 3, and the sorting shaft at the other end is the driven sorting shaft 4. Both ends of the active sorting shaft 3 and the driven sorting shaft 4 pass through the sorting box 1, and a support plate is installed on the outside of the sorting box 1 to install the driving motor, and the output shaft of the driving motor is coaxially connected to the left end of the active sorting shaft 3 through a coupling.

[0026] A slidable sorting roller 10 is installed along the axial direction on both the active sorting shaft 3 and the driven sorting shaft 4. A sorting belt 7 is meshed between the sorting rollers 10 at both ends, and a plurality of drop chutes 8 are provided on the sorting belt 7 for the qualified material particles to fall. A feed port is provided at the top of the right end of the sorting box 1, and a feed hopper 2 connected to the bottom of the jaw crusher is fixedly installed. A large particle material outlet is provided at the left end of the sorting box 1, and the end of the sorting belt 7 is located above the large particle material outlet. The material particles with excessive particle size screened by the sorting belt 7 are transported by the sorting belt 7 and discharged from the large particle material outlet. A qualified material outlet is also provided on the right side of the sorting box 1, and a transfer plate 5 connected to the qualified material outlet and obliquely extending between the upper and lower sides of the sorting belt 7 is installed inside.

[0027] Specifically, Figure 2 and Figure 3 As shown, two slide grooves 16 are opened on the active sorting shaft 3 and the driven sorting shaft 4 along the axial direction, and the sorting roller 10 is coaxially sleeved on the active sorting shaft 3 and the driven sorting shaft 4 respectively. Two sliders 15 sliding in the slide grooves 16 are integrally formed on the inner side of the sorting roller 10, and the length of the slider 15 is smaller than the length of the slide groove 16. Therefore, when one end of the sorting roller 10 is pushed inward by an external force, the sorting roller 10 can slide in the axial direction due to the cooperation of the slider 15 and the slide groove 16, and due to the limiting of the slider 15 and the slide groove 16, when the active sorting shaft 3 and the driven sorting shaft 4 rotate, the sorting roller 10 will be driven to rotate synchronously.

[0028] A corner baffle 6 is fixedly installed on both inner sides of the sorting box 1, and the corner baffle 6 includes a horizontal portion that fits with the end surfaces of the two sides of the sorting belt 7 and a vertical portion connecting the horizontal portion and the top surface of the sorting box 1. Connecting portions that fit with the horizontal portions of the corner baffle 6 are formed on both sides of the sorting belt 7, and in the process of the sorting roller 10 sliding on the sorting shaft, the connecting portions on both sides are always in contact with the horizontal portions of the corner baffle 6 on both sides, and the blanking trough 8 is opened on the sorting belt 7 between the connecting portions on both sides. In this embodiment, the blanking trough 8 is specifically a blanking ring groove opened on the sorting belt 7 and closed at both ends, and the width of the sorting belt 7 between adjacent blanking ring grooves is not greater than the width of the blanking ring groove. A plurality of connecting plates 9 are fixedly installed at equal intervals along the rotation direction between the connecting parts on both sides, and the sorting belts 7 between the adjacent material dropping ring grooves are fixedly installed on the inner side of the connecting plates 9, and the connecting plates 9 are all inclined toward the direction of the large particle material outlet, and the adjacent connecting plates 9 and the corner baffles 6 on both sides form a receiving chamber for receiving and separating material particles, and the feed port is specifically opened at the top of the right end of the material distribution box between the corner baffles 6 on both sides. The materials dropped from the feed port fall into the receiving chamber respectively to reduce the accumulation of material particles and facilitate sorting.

[0029] In addition, a number of equidistantly arranged protrusions are integrally formed on the inner side of the connecting portion of the sorting belt 7, and a number of grooves for the protrusions to be placed and meshed with the protrusions are opened circumferentially on the sorting drum 10. The meshing of the protrusions and the grooves and the fixation of the connecting rods are used to prevent the sorting belt 7 from relative displacement during the sliding process of the sorting drum 10 along the sorting axis.

[0030] A pushing structure for pushing the sorting drum 10 inwardly to slide inwardly is also installed on the inner side of the corner baffle 6. The pushing structure is specifically a stop plate 12 fixedly installed on the inner side of the corner baffle 6, and a stop platform 13 sleeved on the outside of the sorting shaft is also fixedly installed at both ends of the sorting drum 10. The outer end surface of the stop platform 13 is integrally formed with a raised section, a smooth section, and an arc-shaped transition section connected between the raised section and the two ends of the smooth section, and the raised section, smooth section, and arc-shaped transition section of the stop platforms 13 at both ends are mirror-imaged.

[0031] In this embodiment, a vibration mechanism for supporting the material transfer plate 5 is also installed in the sorting box 1 below the material transfer plate 5, and at the same time, striking blocks 14 for striking the material transfer plate 5 are fixedly installed at the ends of the sorting roller 10. The vibration mechanism includes a support platform fixedly installed on the inner side of the sorting box 1, a sleeve 11 fixedly installed at the bottom of the four corners of the material transfer plate 5, a sleeve rod fixedly installed on the support platform and can be respectively extended into the sleeve 11, and a spring sleeved on the sleeve 11 and the outside of the sleeve rod. A limiting slide groove 16 is opened in the sleeve 11, and the end of the sleeve rod extending into the sleeve 11 is integrally formed with a limiting slider 15 that can only slide in the limiting slide groove 16, and the sorting boxes 1 on both sides of the material transfer plate 5 are installed with sealing plates that fit the two sides of the material transfer plate 5. A pressure plate that can be pushed downward by the striking block 14 is integrally formed on the material transfer plate 5.

[0032] When the utility model is used, the driving motor is started, and the driving motor drives the active sorting shaft 3 to rotate, and then drives the sorting rollers 10 at both ends and the driven sorting shaft 4 to rotate through the sorting belt 7, and then the jaw crusher is started and the material particles obtained after crushing enter the feed hopper 2 to the top of the sorting belt 7;

[0033] During the rotation of the sorting belt 7, the raised sections on the abutment platforms 13 at both ends of the sorting drum 10 abut against the abutment plates 12 on the inner sides of the corner baffles 6 on both sides alternately, so that the sorting drum 10 can also slide left and right along the axial direction during the rotation process, and then reciprocate the material particles on the sorting belt 7 to the left and right, so that the material particles that meet the particle size can completely fall from the drop chute 8 into the transfer plate 5 below, while the material particles that do not meet the particle size continue to be transported by the sorting belt 7 to the large particle material outlet and fall, completing the automatic sorting of the material particles;

[0034] During the rotation of the sorting drum 10, the striking block 14 can also strike the pressure plate to make the transfer plate 5 shake up and down to facilitate the discharge of material particles. In this up and down shaking process, the material particles will not enter the top of the sorting belt 7 due to the obstruction of the material particles continuously falling from above and the sorting belt 7.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
