Detailed Implementation

[0016] The invention will now be further described with reference to the accompanying drawings.

[0017] like Figure 1 As shown, the destoning device 10 includes a destoning screen body and a vibration mechanism 500.

[0018] The base 106 of the stone removal device 10 is fixed to a concrete floor or steel structure via a base plate 107. A stone removal screen angle adjustment mechanism 105 is placed at the front end of the base 106; one or more stone removal screen angle adjustment mechanisms 105 may be used. In this embodiment, two stone removal screen angle adjustment mechanisms 105 are used, distributed on both sides of the stone removal device 10; if a single stone removal screen angle adjustment mechanism 105 is used, it is placed in the middle of the stone removal device 10. The stone removal screen angle adjustment mechanism 105 is existing technology and can adopt an adjusting screw and sleeve structure, or an adjusting rod structure with matching height adjustment holes.

[0019] The destone screen body is placed on the base 106 by rubber springs 104. Based on the material flow path direction, multiple rubber springs 104 are arranged at both the front and rear ends. In this embodiment, two rubber springs 104 are placed at the front end and four rubber springs 104 are placed at the rear end.

[0020] like Figure 1 As shown, a side bracket 103 is fixed on the base 106, and the feed inlet 101 is fixed on the side bracket 103. Figure 4 As shown, this embodiment uses two feed inlets 101, which are connected to the uniform feeding mechanism 200 via feed flexible connectors 102. The feed inlet 101 is located at the top of the destoner, through which the raw grain to be cleaned enters; the feed inlet flexible connector 102 is located directly below the feed inlet 101.

[0021] In one embodiment, a uniform air distribution plate 460 is provided at the bottom of the destoning sieve body. Specifically, the uniform air distribution plate 460 is provided at the bottom of the second sieve grid 400. Ventilation holes 461 are evenly distributed on the uniform air distribution plate 460. The destoning device also includes a uniform air distribution plate cleaning mechanism 700, which includes a blowing assembly and a blowing drive assembly.

[0022] A jetting assembly is positioned below the air distribution plate 460 to clean the lower surface of the air distribution plate. In one embodiment, such as... Figure 2 , Figure 3 As shown, the blowing assembly includes a first blowing assembly 710 and a second blowing assembly 720 arranged opposite to each other; the first blowing assembly 710 and the second blowing assembly 720 are arranged in opposite directions; both the first blowing assembly 710 and the second blowing assembly 720 include a blowing main pipe 711, and nozzles 712 are arranged in parallel on the blowing main pipe 711; the blowing main pipe 711 is arranged on the blowing mounting base 713.

[0023] The blowing drive assembly is connected to the blowing assembly and is used to drive the blowing assembly to perform linear reciprocating motion along the air distribution plate. Specifically, the blowing drive assembly includes a first blowing drive assembly 730 and a second blowing drive assembly 740 arranged opposite to each other; the first blowing drive assembly 730 is connected to the first blowing assembly 710; the second blowing drive assembly 740 is connected to the second blowing assembly 720. The first blowing drive assembly 730 is preferably a cylinder; the second blowing drive assembly 740 is preferably a cylinder.

[0024] In one embodiment, the air distribution plate cleaning mechanism further includes a guide rod assembly 750 for guiding the linear reciprocating motion of the spray assembly. The guide rod assembly 750 includes a plurality of guide rods 751. In this embodiment, there are three guide rods, which are respectively installed at both ends and the middle of the spray mounting base 723. The guide rods 751 are slidably connected to the spray pipe mounting base 723.

[0025] A second partition 430 is provided inside the second screen frame of the second screen grid 400, dividing the second screen frame into several second grids 440. A second elastic body 450 is provided within each second grid 440, serving as a second cleaning mechanism. Vibration of the destoning screen body causes the second screen grid 400 and the second elastic body 450 to vibrate, thereby cleaning the upper surface of the air distribution plate 460. Preferably, the second elastic body 450 is square.

[0026] The air distribution plate cleaning mechanism 700 is a movable structure, including a base 760, a guide rod assembly 750, a first blowing assembly 710, a second blowing assembly 720, a first blowing drive assembly 730, and a second blowing drive assembly 740. For example... Figure 2 , Figure 3As shown, the first jet-blowing drive assembly 730 drives the first jet-blowing assembly 710 to move left and right, and the second jet-blowing drive assembly 740 drives the second jet-blowing assembly 720 to move right and left. During operation, the nozzles 712 arranged on the first jet-blowing assembly 710 and the second jet-blowing assembly 720 intermittently spray high-pressure compressed air to clean the lower part of the air distribution plate 460. Combined with the second elastic body 450 arranged on the upper part of the air distribution plate 460, the upper surface of the air distribution plate 460 is cleaned under the vibration of the destone removal device, thereby realizing the self-cleaning form of the entire air distribution plate and achieving completely maintenance-free operation of this part. The nozzles 712 arranged on the first jet-blowing assembly 710 and the second jet-blowing assembly 420 are preferably arranged in a matrix of evenly distributed high-pressure air nozzles for periodic pulse jet cleaning.

[0027] like Figure 9-14 As shown, the first screen 300 includes a first screen grid 310 and a second screen grid 320. The first screen grid 310 includes a first screen frame 311 and a first screen surface 312. The first screen surface 312 forms a pre-separation zone 330, a stratification zone 340, and a separation zone 350 along the material movement direction. The pre-separation zone 330 is used to pre-separate the material thrown and conveyed by the feeding mechanism. The stratification zone 340 is used to stratify the material and stones under the action of wind and vibration. The separation zone 350 is used to convey the separated and stratified material and stones to the stone outlet end of the second screen grid via the feed plate.

[0028] In one embodiment, the first screen surface 312 where the pre-separation zone 330 is located is a screen plate structure, and a first screen hole 331 is provided on the first screen surface 312 where the pre-separation zone is located. The first screen hole 331 is an elongated hole and is provided along the width direction of the first screen grid.

[0029] In one embodiment, the first screen surface 312 where the layered area 340 is located is a woven mesh structure.

[0030] In one embodiment, the first sieve surface 312 where the separation zone 350 is located is a sieve plate structure, and a first sieve hole 351 is provided on the first sieve surface 312 where the separation zone 350 is located. The first sieve hole 351 is an elongated hole and is arranged along the length direction of the first sieve grid 310. The first sieve hole 351 is arranged perpendicularly to the first sieve hole 331.

[0031] The second sieve grid 320 is detachably mounted on the first sieve grid 310. The second sieve grid 320 includes a second sieve frame 321 and a second sieve surface 322. The second sieve frame 321 is detachably connected to the first sieve frame 311. Specifically, the second sieve frame 321 and the first sieve frame 311 are detachably connected via a first hook 313 and a second hook 323. The second sieve surface 322 and the first sieve surface 312 constitute the first sieve surface.

[0032] The first screen surface 322 forms a heavy material discharge area 360 and a light impurity classification area 370 along the material movement direction. The heavy material discharge area 330 is used to allow heavy materials to pass through the first screen surface 322 to the second screen grid under the action of wind. In one embodiment, the first screen surface 322 where the heavy material discharge area 360 is located is provided with a first screen hole 361, which is arranged along the length direction of the first screen grid 300.

[0033] The light impurity grading zone 370 is used for grading and concentrating light impurities. In one embodiment, a first screen hole 371 is provided on the first screen surface 322 where the light impurity grading zone 370 is located. The first screen hole 371 is circular.

[0034] In one embodiment, a first partition 380 is provided inside the first screen frame 311, which is used to divide the first screen frame 311 into a plurality of first grids 381. A first partition 380 is provided inside the second screen frame 321, which is used to divide the second screen frame 321 into a plurality of first grids 381.

[0035] A first elastic body 390 is installed in the first grid 381 below the stratification zone 340 and the separation zone 350 and is supported by a steel wire woven mesh. The first elastic body 390 is used to clear the blockage of the first screen surface 312 where the stratification zone 340 and the separation zone 350 are located, and also to evenly distribute and classify the material layer under the action of wind.

[0036] In one embodiment, such as Figure 15-19 As shown, the second sieve 400 includes a second sieve first 410 and a second sieve second 420. The second sieve first 410 includes a second sieve frame first 411 and a second sieve surface first 412. Preferably, the second sieve surface first 412 is a woven mesh structure. The second sieve second 420 includes a second sieve frame second 421 and a second sieve surface second 422. The second sieve surface second 422 is also a woven mesh structure. The second sieve frame second 421 is detachably connected to the second sieve frame first 411. Specifically, the second sieve frame second 421 and the second sieve frame first 411 are detachably connected via second hook first 413 and second hook second 423. The second sieve surface first 412 and the second sieve surface second 422 constitute the second sieve surface.

[0037] In one embodiment, a second partition 430 is provided inside the second screen frame 411, which is used to divide the second screen frame 411 into a plurality of second grids 440. A second elastic body 450 is provided inside the second grids 440 for cleaning the clogged second screen surface 412.

[0038] In one embodiment, a second partition 430 is provided inside the second screen frame 421, and the second partition 430 is used to divide the second screen frame 421 into a plurality of second grids 440. A second elastic body 450 is provided inside the second grid 440 for cleaning the blocked second screen surface 422.

[0039] like Figure 5 , Figure 6 As shown, the destone sieve body contains two layers of drawer-type sieve compartments, namely the first sieve compartment 300 and the second sieve compartment 400.

[0040] like Figures 9-14 As shown, the first sieve 300 is segmented, and the first sieve 300 adopts a two-section structure, namely, the first sieve 300 is the first sieve 1 310 and the first sieve 2 320, and the two sections are connected by the first hook 1 313 and the first hook 2 323.

[0041] like Figures 9-14 As shown, the first sieve grid 310 includes multiple segmented first sieve surfaces 312. This embodiment adopts a three-segment design. The first section is the screen surface of the pre-separation zone 330, which is made of steel plate with perforated screen plate. Its first screen hole 331 is a transverse (long axis along the width of the screen surface) elongated hole, which allows the aggregate of stones and heavy materials after the material throwing motion in the early stage to fall quickly to the lower layer, reducing the stone removal pressure of the second screen surface. The second section is a 340-degree sieve surface with a steel wire mesh. Under the action of wind and vibration, the materials and stones are separated into layers according to their different specific gravities. The third section is the screen surface of the separation zone 350, which is made of steel plate with perforated screen plate. Its first screen hole 351 is a longitudinal (long axis direction is perpendicular to the width direction of the screen surface) elongated hole. The stones after the material and stones are separated can fall quickly onto the second screen grid 400 according to their different specific gravities. After passing through the material guide plate 470, this part of the material falls to the front end of the second screen grid 400, thereby effectively reducing the running distance when the stones are concentrated and discharged upward.

[0042] The first screen frame 311, the first screen frame 321, and the first partition 380 form the skeleton of the first screen grid 300, which can be a wooden frame, an aluminum alloy frame, or a steel frame or a combination thereof.

[0043] The steel wire woven mesh in the layered zone 340 and the elongated perforated steel plate screen plate in the separation zone 350 form a skeleton below the screen, creating multiple first grids 381. Multiple first elastic bodies 390 are placed in the first grids 381 to prevent the woven screen surface from being blocked by fine particles, and to facilitate the uniform distribution and grading of the material layer under the action of wind. The first elastic body 390 is preferably spherical.

[0044] like Figures 15-19As shown, the second sieve 400 is segmented, and the first sieve 320 contains multiple segmented sieve surfaces. This embodiment adopts a two-segment design. The first section is the screen surface of the heavy material feeding area 360, which is made of perforated steel plate. The first screen hole 361 is a longitudinal elongated hole, with the long axis perpendicular to the width of the screen surface. Under the action of wind, the heavy material is quickly passed through the screening area to the second screen 400; The second section is the screen surface of the light impurity grading zone 370, which uses a perforated steel plate screen. Its first screen hole 371 is a round hole, used to classify and concentrate light impurities.

[0045] The second screen surface 412 on the upper part of the second screen grid 410 is made of steel wire woven mesh, and the second screen surface 422 on the upper part of the second screen grid 420 is made of steel wire woven mesh. A uniform air distribution plate 460 is provided at the lower part of the second screen grid 410 and the second screen grid 420. The uniform air distribution plate 460 is a perforated screen plate, and its ventilation holes 461 are in the form of round holes.

[0046] The second sieve frame 411, the second sieve frame 421, and the first partition 430 form the skeleton of the second sieve grid 400, which can be a wooden frame, an aluminum alloy frame, or a steel frame or a combination thereof.

[0047] The framework between the wire mesh and the air distribution plate is divided into multiple second grids 440, and each second grid 440 is provided with a second elastic body 450 to remove dust accumulation caused by airflow on the air distribution plate, prevent the holes on the air distribution plate from becoming clogged, and thus affect the airflow area. The second elastic body 450 is preferably a square cleaning block.

[0048] The destoning screen body is welded with a light grain outlet 115, a heavy grain outlet 116, and a destoning inlet 117. The light grain outlet 115 is located at the rear of the destoning screen body, the heavy grain outlet 116 is located at the rear of the destoning screen body, and the destoning inlet 117 is located at the front of the destoning screen body. In this embodiment, there are two light grain outlets 115, two heavy grain outlets 116, and one destoning inlet 117. Multiple destoning inlets 117 can also be designed.

[0049] like Figure 1 As shown, the stone removal screen body is equipped with a lightweight material discharge adjustment component 480, a material feeding plate 470, and a reverse air blowing plate adjustment component 490.

[0050] like Figure 1 , Figure 6 As shown, the lightweight material discharge adjustment assembly 480 includes a third adjusting screw 481, a third adjusting seat 482, and a first adjusting nut 483. The third adjusting screw 481 drives the third adjusting seat 482, thereby changing the relative distance between its baffle and the upper plane of the first screen surface 322, separating the heavy material at the bottom and the lightweight material at the top of the material flow.

[0051] like Figure 6 As shown, the feed plate 470 is used to change the path of the material falling from the first screen 300 onto the second screen 400, making it easier to remove stones or mud.

[0052] like Figure 1 , Figure 6 As shown, the back-blowing plate adjustment assembly 490 includes a fourth adjusting screw 491, a fourth adjusting seat 492, a second adjusting nut 493, and a hinge 494. The right end of the back-blowing plate adjustment assembly 490 is fixed to the de-stone screen body via the hinge 494. By adjusting the length of the fourth adjusting screw 491, the distance between the fourth adjusting seat 492 and the second screen surface 412 is changed, thereby changing the air velocity flowing through that area, thus separating the material from the stones and mud within it, and smoothly discharging the stones and mud from the stone outlet.

[0053] One vibration mechanism 500 is arranged on each side of the destoning screen body. The vibration mechanism 500 is preferably a vibration motor. The vibration mechanism 500 is mounted on the vibration mechanism mounting base 510. The vibration mechanism 500 can rotate relative to the destoning screen body and is connected to the destoning screen body through an adjustable fixing component 520.

[0054] Specifically, the vibration mechanism mounting base 510 is rotatably mounted on the destoning screen body. A boss 114 is provided on the destoning screen body, and the vibration mechanism mounting base 510 is rotatably connected to the boss 114.

[0055] The destoning device also includes a destoning vibration adjustment mechanism 600, which is connected to the destoning screen body and the vibration mechanism 500 respectively. This mechanism is used to adjust the installation angle of the vibration mechanism to ensure that the excitation angles of the vibration mechanisms 500 are consistent. Specifically, for example... Figure 7 , Figure 8 As shown, the stone removal vibration adjustment mechanism 600 includes a first adjustment seat 610, a second first adjustment seat 620, and a first adjustment screw 630.

[0056] The first adjusting seat 610 is disposed on the stone removal screen body. Specifically, the first adjusting seat 610 includes a first U-shaped seat 611 and a first pin 612. The first pin 612 is mounted on the first U-shaped seat 611.

[0057] The vibration mechanism is mounted on the mounting base 510. Specifically, the first adjusting base 620 includes a first U-shaped base 621 and a first pin 622. The first pin 622 is mounted on the first U-shaped base 621.

[0058] One end of the first adjusting screw 630 is connected to the second first adjusting seat 620, and the other end of the first adjusting screw 630 is movably connected to the first adjusting seat 610. Specifically, one end of the first adjusting screw 630 is threaded onto the second first pin 622; the other end of the first adjusting screw 630 is movably connected to the first first pin 612. First locking components 640 are provided on the first adjusting screws 630 on both sides of the first first pin 612. The first locking components 640 are preferably lock nuts.

[0059] In one embodiment, such as Figure 6 As shown, the adjustable fixing assembly 520 includes a fixing member 521 and arc-shaped waist holes 522 spaced circumferentially on the outer side of the destoning screen body of the boss 114. The fixing member 521 is preferably a fixing bolt. The fixing member 521 is installed in the arc-shaped waist hole 522 to connect the vibration mechanism mounting seat and the destoning screen body. Loosening the fixing member allows the destoning vibration adjustment mechanism to rotate the vibration mechanism mounting seat relative to the boss to a target angle. At the same time, after the fixing member rotates to the target position in the arc-shaped waist hole, the fixing member is locked, thereby locking the vibration mechanism and the destoning screen body.

[0060] The vibration mechanism mounting base 510 is in the form of a disc, and its center position cooperates with the cylindrical boss 114 provided on the destoning screen body. It can rotate on the boss 114. The part where it connects with the destoning screen body is in the form of an arc-shaped waist hole 521. A first U-shaped seat 621 is welded on the vibration mechanism mounting base 510. A first pin 622 is assembled on the first U-shaped seat 621. The first pin 622 has an internal thread and cooperates with the first adjusting screw 630. The other end of the first adjusting screw 630 cooperates with the first pin 612. The first pin 612 is provided with a through hole. The first adjusting screw 630 can rotate freely in the through hole of the first pin 612. The first pin 612 is assembled on the first U-shaped seat 611. The first U-shaped seat 611 is fixed to the destoning screen body by bolts or welding.

[0061] In actual use, if it is necessary to fine-tune the angle of the vibration mechanism 500, the fixing part 521 of the vibration mechanism 500 needs to be loosened, and the first locking assembly 640 needs to be loosened at the same time. The first adjusting screw 630 can be rotated. The rotation of the first adjusting seat 620 can be achieved by the rotation of the first pin 612 and the first pin 622 and the change of the first adjusting screw 630. After the fine-tuning is completed, the first locking assembly 640 and the fixing part 521 are tightened with torque, thereby achieving the fine-tuning of the angle of the vibration mechanism 500 and achieving the effect of balanced vibration of the entire destoning screen body. This solves the problem of screen body shaking caused by uneven vibration of the screen body due to manufacturing and installation in actual production.

[0062] Two vibrating motors are fixed to the two sides of the destoning screen body by fixing parts 521 and vibration mechanism mounting base 510. The two vibrating motors rotate in opposite directions, causing the vibrating body (including the destoning screen body, material distribution box 204, suction hood 9, first screen grid 300, second screen grid 400, etc.) to reciprocate linearly. Since the destoning screen body has a certain installation angle, it can drive the material to make throwing motion.

[0063] In this invention, a vibrating motor is placed on each side of the stone removal screen body, and they operate in opposite directions. Their lateral excitation forces cancel each other out, while their excitation forces perpendicular to the motor axis are combined. The entire vibrating body is placed on a rubber spring 104. Under the excitation force of the vibrating motors, the entire vibrating body moves along... Figure 3 The direction of the middle arrow indicates linear vibration.

[0064] This invention boasts high production capacity and high destoning efficiency: the wide and long screen surface increases the screening area and improves the destoning effect. The addition of a vibration motor fine-tuning mechanism can maximize the vibration performance of the entire machine and enhance its overall operating characteristics.

[0065] like Figure 1 As shown, the destoning device also includes an air suction chamber, which is located above the destoning screen body. Figure 6 As shown, a suction baffle 113 is provided in the suction chamber, dividing it into a first suction chamber 111 and a second suction chamber 112. The first suction chamber 111 cooperates with the first sieve grid 310; the second suction chamber 112 cooperates with the first sieve grid 320. The suction port 110 is fixed on the side bracket 103. In this embodiment, one suction port 110 is used, which is connected to the suction hood 108 via a suction flexible connector 109.

[0066] In one embodiment, such as Figure 20 , Figure 21 As shown, damper adjustment mechanisms 800 are respectively provided on the first suction chamber 111 and the second suction chamber 112, including dampers 810 and damper angle adjustment components. The damper 810 is installed in the first suction chamber 111 or the second suction chamber 112 via a damper pivot 811.

[0067] like Figure 22 , Figure 23 As shown, the damper angle adjustment assembly includes a second adjustment seat 820, a second adjustment seat 830, a second adjustment screw 840, and a second locking assembly 850.

[0068] The second adjusting seat 820 is mounted on the damper shaft 811. Specifically, the second adjusting seat 820 includes a second U-shaped seat 821 and a second pin 822. The second pin 822 is mounted on the second U-shaped seat 821, and a connecting hole is provided on the second pin 822 for connecting the second adjusting screw 830.

[0069] The second adjusting seat 830 is used to connect the first suction chamber 111 or the second suction chamber 112. Specifically, the second adjusting seat 830 includes a second U-shaped seat 831 and a second pin 832. The second pin 832 is provided on the second U-shaped seat 831, and a through hole is provided on the second pin 832.

[0070] One end of the second adjusting screw 840 is mounted on the second adjusting seat 820, and the second adjusting screw 840 can slide relative to the second adjusting seat 820. The other end of the second adjusting screw 840 passes through the second adjusting seat 830 and is mounted on the second locking assembly 850. In use, rotating the second adjusting screw 840 causes it to slide on the second adjusting seat 820, which in turn causes the second adjusting seat 820 and the damper shaft 811 to rotate, thereby adjusting the angle of the damper 810.

[0071] In one embodiment, the second locking assembly 850 includes a second locking member 851 and an elastic clamping member 852. The second locking member 851 is disposed on the second adjusting screws 840 on both sides of the second pin 832. The elastic clamping member 852 is disposed inside the end of the second locking member 851; adjusting the position of the second locking member 851 on the second adjusting screw 840 adjusts the clamping force of the elastic clamping member 852.

[0072] In one embodiment, the damper adjustment mechanism 800 further includes an indicator component 860 for indicating the rotation angle of the damper. Specifically, the indicator component 860 includes a cooperating pointer 861 and a dial 862. The pointer 861 is disposed on the second adjustment seat 820, and the dial 862 is disposed on the first air intake chamber 111 or the second air intake chamber 112. The dial 862 is set with an angle value corresponding to the damper position.

[0073] In one embodiment, the damper adjusting mechanism 800 further includes a handle assembly 870 for rotating the second adjusting screw 740. The handle assembly 870 includes a handle 871, which is disposed at the lower end of the second adjusting screw 740 via a cylindrical pin 872. The handle 871 is preferably a star-shaped handle.

[0074] like Figure 20 , Figure 21 As shown, a connecting flange is installed on the air intake 110, requiring the equipment to be connected to an external air network during operation. Figure 6 , Figure 7 As shown, the suction baffle 113 divides the suction chamber into two parts, with a damper 810 installed in both the first and second suction chambers 111 and 112. Figure 22 , Figure 23As shown, taking the adjustment of the second suction chamber 112 as an example: the damper shaft 811 is connected to the second U-shaped seat 821 by a set screw 812. The top of the second U-shaped seat 821 is equipped with a pointed pointer 861, with a corresponding scale 862 at the rear, on which the angle value corresponding to the damper position is engraved for indication during adjustment. The scale 862 and the second U-shaped seat 831 are fixedly connected to the suction port 110 by bolts. The second U-shaped seat 821 is equipped with a second pin 822, which has an internal thread. It is connected to the second adjusting screw 840. The other end of the second adjusting screw 840 is connected to the second pin 832 through a through hole and is mounted on the second U-shaped seat 831. An elastic clamping member 852 is provided at the corresponding position of the second adjusting screw 840. A second locking member 851 is provided at the lower part of the elastic clamping member 852 for clamping. The clamping force of the elastic clamping member 852 can be adjusted by adjusting the position of the second locking member 851. A handle 871 is provided at the lower end of the second adjusting screw 840. The two are fixed by a cylindrical pin 872.

[0075] The working principle of the damper adjustment mechanism: In the initial position, the damper is vertically upward, indicating the maximum damper opening, corresponding to a scale value of 90°. To reduce the airflow, handle 871 is turned, which in turn rotates the second adjusting screw 840. This causes the second pin 822 to slide on the adjusting screw 840. The second pin 822 then rotates the second U-shaped seat 821 clockwise around the damper shaft 811, thus rotating the damper clockwise. As the damper closes, the airflow decreases, which is indicated by the differential pressure gauge 118 and the dial 862. Figure 1 .

[0076] The suction chamber of this invention adopts a front and rear separated structure, which can adjust the air volume of the first and second suction chambers arranged in front and rear of the stone removal screen body according to user needs. The adjustment is novel, the indication is clear, the production efficiency is high, the grading, sand and mud removal performance is good, the energy consumption is low, there is no dust emission, the noise is low, and the operation, use and maintenance are convenient.

[0077] The upper flange of the air intake 110 is connected to the external air network, and the inside of the air intake hood 108 is under negative pressure. The air path is as follows: Figure 6 As shown, the airflow moves upward from the bottom of the destone screen body, passing through the second screen surface and the first screen surface. The airflow can keep the material suspended on the screen surface. After passing through the first screen surface, it is separated by the suction baffle 113 in the suction hood 108. The airflow of the first suction chamber 111 and the second suction chamber 112 is locally controlled by the damper adjustment mechanism 800.

[0078] In one embodiment, such as Figure 1 , Figure 6As shown, the destoning device also includes a material distribution box 200. The material distribution box 200 and the suction hood 108 are installed on the destoning screen body. The material enters the material distribution box 200 and is evenly distributed in the feed width direction. Since the destoning screen body has a certain inclination angle, the material distribution box 200 is installed on the destoning screen body to form a certain included angle, which is the same as the destoning screen body and downward in the direction of material movement.
