DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 11 The present invention provides a technical solution: a method for recycling waste ceramics, the method comprising the following steps: step 1: the staff places the waste ceramic workpiece to be processed into a crushing box 1; step 2: the crushing mechanism gradually squeezes the workpiece until the ceramic material and the metal material of the workpiece are separated; step 3: the ceramic material will be pushed to the bottom of the crushing box 1 by the crushing mechanism and then discharged after being crushed by the crushing mechanism, and the metal material will remain on the crushing mechanism, and the staff can take out the metal material before placing the waste ceramic workpiece again; wherein the crushing mechanism described in step 1 and step 2 includes a bearing plate 2 and a driving assembly; the bearing plate 2 is slidably connected to the crushing box 1 in the horizontal direction; The bearing plate 2 is provided with a number of equidistantly distributed receiving grooves 3, and the sides of the receiving grooves 3 are provided with support members 4, and the support members 4 are fixedly mounted on the top of the bearing plate 2; a support plate 5 is provided directly below the receiving grooves 3, and a plurality of the support plates 5 are fixedly connected by connecting brackets 6; the connecting brackets 6 are slidably connected to the crushing box 1 in the vertical direction; a pressing plate 7 and a hydraulic cylinder 8 are provided above the bearing plate 2, and the hydraulic cylinder 8 is used to drive the pressing plate 7 to cooperate with the support plate 5 to extrude the workpiece; each time the pressing plate 7 works, it can cooperate with the driving assembly to move the support plate 5 upward to a certain height, the height difference between the support plate 5 and the bearing plate 2 is reduced, and the workpiece fragments on the support plate 5 are closer to the bottom surface of the pressing plate 7.

[0018] During operation, the staff first pulls the carrier plate 2 out of the crushing box 1, or a linear motor can be set in the crushing box 1 to move the carrier plate 2 in the horizontal direction; then the staff removes the discarded workpieces Fig.11In the state shown, the workpiece is placed on the carrier plate 2, the two ends of the metal parts on the workpiece are placed on the support member 4, and the insulating material on the workpiece is located in the receiving groove 3; after the workpiece is placed, the staff pushes the carrier plate 2 into the crushing box 1 again. After the carrier plate 2 is placed in place, the receiving groove 3 is located directly above the support plate 5. In the initial state, the top surface of the support plate 5 is close to the bottom end of the workpiece; then the hydraulic cylinder 8 drives the pressing plate 7 to move downward to start working; it should be noted that the support member 4 is a soft material. When the pressing plate 7 squeezes the workpiece, the support member 4 can be concave under the squeezing action, so that the bottom end of the workpiece can contact with the top surface of the support plate 5, and the pressing plate 7 The support plate 5 can be used to crush the ceramic material of the workpiece; then the hydraulic cylinder 8 drives the pressing plate 7 to move upward. At this time, the height of the pressing plate 7 moving upward can be lower than the height of the initial state. The purpose of the pressing plate 7 moving upward is to allow the crushed ceramic material to be evenly scattered on the support plate 5, and the ceramic material stacked together is greatly reduced. The possibility of the lower layer of ceramic fragments splashing around when the pressing plate 7 squeezes the ceramic material can be reduced, which can better protect the components in the crushing box 1 and increase the service life of each component in the crushing box 1. At the same time, the pressing plate 7 can also cooperate with the driving component to drive the connecting bracket 6 and the support plate 5 to move upward for a small distance during the upward movement. After the ceramic material is crushed, its height will be reduced, and the support plate 5 will move upward to make the ceramic fragments closer to the bottom surface of the pressing plate 7. The next time the pressing plate 7 works, the ceramic material will be further crushed; then the hydraulic cylinder 8 will drive the pressing plate 7 to move downward again to squeeze the ceramic material, and the ceramic material will be further crushed; after the pressing plate 7 has worked for many times, the ceramic material on the workpiece will be crushed to a certain extent by the pressing plate 7, and the metal parts will be separated from the ceramic material. Since the support member 4 is made of soft material, when the pressing plate 7 squeezes the ceramic material, the force acting on the metal parts will be absorbed by the support member 4, and the metal parts will not bend due to the pressure; then the hydraulic cylinder 8 can be driven The pressing plate 7 moves upward to the initial position, at which time the driving assembly will drive the support plate 5 to move downward back to the initial position. It should be noted that since the ceramic material is directly above the support plate 5 when being squeezed, and the pressing plate 7 is gradually squeezed when working, only a small amount of ceramic fragments will splash, so the ceramic fragments basically stay on the support plate 5; then the staff can pull the supporting plate 2 out of the crushing box 1 again to carry out the next workpiece processing work. During the withdrawal of the supporting plate 2, the ceramic fragments on the support plate 5 will be pushed out, and the ceramic fragments will fall onto the crushing mechanism arranged under the crushing box 1 for fine crushing, and then be discharged from the bottom of the crushing box 1.

[0019] Specifically, Figure 2 and Figure 3As shown, the crushing box 1 includes a box body 9, a door body 10, a feed port 11 and a discharge port 12; the door body 10 is hinged to the box body 9 through a hinge, the feed port 11 is opened on the door body 10 and is located on the side of the supporting plate 2; the discharge port 12 is opened at the bottom of the box body 9, and a baffle 13 is arranged in the feed port 11.

[0020] During operation, the door 10 can facilitate the inspection and repair of the components in the box 9, and the baffle 13 can prevent ceramic fragments from splashing out from the feed port 11 and injuring the staff.

[0021] Specifically, Figure 2 , Figure 3 and Fig. 9 As shown, the driving assembly includes a push block 14, which is elastically slidably connected to the crushing box 1 and is arranged in a stepped shape, and the side edges of the push block 14 adjacent to the horizontal side wall are arranged in an inclined shape; the horizontal side wall of the push block 14 is used to support the connecting bracket 6, and the inclined side wall is used to drive the connecting bracket 6 to move upward; a steel rope 15 is fixedly connected to the push block 14, and a winding roller 16 is fixedly connected to the crushing box 1 at one end of the steel rope 15 away from the push block 14, and the winding roller 16 is fixedly connected to the crushing box 1, and the winding roller 16 is connected to an incomplete gear 17 through a one-way bearing transmission, and a rack rod 18 that can mesh with the incomplete gear 17 is arranged on the side of the incomplete gear 17, and the rack rod 18 is slidably connected to the crushing box 1, and the rack rod 18 is fixedly connected to the pressure plate 7 through a connecting block.

[0022] During operation, in the initial state, the rack rod 18 is located above the incomplete gear 17 (not meshing with the incomplete gear 17); when the pressure plate 7 drives the rack rod 18 to move upward for a certain distance, the rack rod 18 meshes with the incomplete gear 17, and at this time, the rack rod 18 moves downward to drive the incomplete gear 17 to rotate. Under the action of the one-way bearing, when the rack rod 18 moves upward, the incomplete gear 17 will not drive the winding roller 16 to rotate. At this time, the support plate 5 remains stationary, and when the pressure plate 7 moves downward to extrude the ceramic material of the workpiece, the support plate 5 remains stationary and cooperates with the pressure plate 7 to crush the ceramic material; when the pressure plate 7 completes an extrusion work and moves upward, when the rack rod 18 drives the incomplete gear 17 to rotate again, the incomplete gear 17 will drive the winding roller 16 to rotate a certain angle, and the winding roller 16 will pass through the steel rope 1 5 drives the push block 14 to move toward the side close to the connecting bracket 6, and the inclined side wall of the push block 14 drives the connecting bracket 6 and the supporting plate 5 to move upward; each time the pressing plate 7 completes a work and moves upward, it will start the push block 14 through the rack rod 18, the incomplete gear 17, the winding roller 16 and the steel rope 15 to push the supporting plate 5 to move upward by a step height, so that the ceramic fragments squeezed from the top of the supporting plate 5 can be closer to the bottom surface of the pressing plate 7, and then the horizontal side wall of the push block 14 will support the connecting bracket 6 and the supporting plate 5, which can ensure that the supporting plate 5 can stably cooperate with the pressing plate 7 to crush the ceramic material. After the pressing plate 7 completes the crushing work and moves upward to the initial position, the rack rod 18 is disengaged from the incomplete gear 17, and the force acting on the push block 14 disappears, and the push block 14 returns to the initial position under the elastic force of the spring.

[0023] Specifically, Figure 3 As shown, a stopper 19 is provided directly above the support member 4 , and the stopper 19 is fixedly mounted on the bottom of the pressing plate 7 .

[0024] During operation, the stopper 19 can be connected to the support member 4 through the setting of the stopper 19. After the bottom surface of the stopper 19 is in contact with the top surface of the support member 4, it can play a role of a barrier, thereby ensuring that the ceramic material will not be fragmented when it is squeezed.

[0025] Specifically, Figure 3 As shown, the support member 4 and the stopper 19 are both made of soft materials.

[0026] During operation, the support member 4 can be made of sponge, and the stopper 19 can be made of soft rubber. The metal member can be better fitted on the support member 4, and the squeezing effect of the stopper 19 on the metal member can also be greatly reduced.

[0027] Specifically, Figure 4-Figure 6As shown, the support plate 5 is composed of a base 20, a top plate 21 and a push plate 22. The base 20 is fixedly mounted on the connecting bracket 6, the top plate 21 is hinged on the top of the base 20, the push plate 22 is slidably connected to the base 20 in the vertical direction, and the push plate 22 is connected to the top plate 21 by a pull rope; a wedge block 23 capable of driving the push plate 22 to move upward is provided on the side of the push plate 22, and the wedge block 23 is fixedly mounted on the bottom of the bearing plate 2.

[0028] During operation, after the ceramic material on the workpiece is separated from the metal material, the carrying plate 2 will move outward and drive the wedge block 23 to move synchronously. The wedge block 23 will drive the push plate 22 to move upward from the inside to the outside in sequence. When the push plate 22 moves upward, it will drive one end of the top plate 21 to move upward through the pull rope. The top plate 21 will rotate around its rotating axis, and the top plate 21 will tilt up near one end of the push plate 22. Then the powdery and granular ceramic material remaining on the top plate 21 can fall to the bottom of the crushing box 1 along the inclined top plate 21; this can prevent the workpiece from slipping and uneven force when it contacts the powdery and granular ceramic material the next time the workpiece is crushed, thereby affecting the crushing effect.

[0029] Specifically, Figure 4-Figure 8 As shown, a cavity 24 is provided in the base 20, a piston 25 is slidably installed in the cavity 24, the piston 25 is fixedly connected to a piston rod 30, the bottom end of the piston rod 30 passes through the base 20 and is fixedly connected to the crushing box 1; an air bag 26 is installed on the base 20, and the air bag 26 is connected to the cavity 24 through a one-way valve 27; an air outlet 28 is provided on the base 20, and the air bag 26 is connected to the air outlet 28, and an air jet hole 29 is provided on the push plate 22, and the air outlet 28 can be connected to the air jet hole 29 when the push plate 22 moves upward to the highest point.

[0030] During operation, each time the pressing plate 7 completes the extrusion work and the supporting plate 5 moves upward, the piston 25 will move downward relative to the base 20, and the piston 25 will press the air in the cavity 24 into the airbag 26 for storage through the one-way valve 27; when the push plate 22 moves upward to the highest point, the jet hole 29 docks with the air outlet hole 28, and then the air in the airbag 26 will be quickly ejected, and the ejected air can blow off a small amount of powdered and granular ceramic material adhering to the top plate 21, which can better prevent the powdered and granular ceramic material from affecting the subsequent crushing of the workpiece.

[0031] Specifically, Figure 8 As shown, the top end of the air injection hole 29 is arranged to be inclined.

[0032] During operation, when the push plate 22 moves upward to the highest point, the top plate 21 is in an inclined state. At this time, the air jet holes 29 face the top plate 21 , and the air jetted from the air jet holes 29 can better contact the top plate 21 .
