DETAILED DESCRIPTION

[0038] 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.

[0039] The present invention provides a technical solution: a garbage drying device for a garbage incineration power plant, such as Figure 1 , 2 As shown, it includes a drying drum 201 and an elevator 102. The drying drum 201 is rotatably arranged on a drum bracket 202. The drum bracket 202 can be fixed on the ground. A dryer 203 is fixed on the drum bracket 202. The outlet of the drying drum 201 can be connected to a subsequent processing device. The inlet of the drying drum 201 is connected to the outlet of a chute 204. The garbage falls into the drying drum 201 through the chute 204. The drying drum 201 can turn over the garbage and cooperate with the dryer 203 to further dry the garbage, thereby improving the efficiency of garbage drying.

[0040] like Figure 1 , 4As shown, the entrance of the slide 204 is arranged at the bottom of the box 101, the bottom of the box 101 has an opening, a squeezing mechanism 300 is arranged in the box 101, and a garbage entrance is opened at the top of the box 101. The elevator 102 can drive the garbage bucket 400 to rise, and the garbage bucket 400 puts the garbage into the garbage entrance of the box 101. The elevator 102 is a common device for transporting goods, including components such as a hydraulic cylinder, a chain and a lifting platform. The lifting platform is lifted by the hydraulic cylinder and the chain. The elevator 102, the box 101 and the slide 204 can be fixed on the ground, and the garbage bucket 400 is driven to rise by the elevator 102, and the garbage bucket 400 pours the garbage into the box 101, thereby reducing the labor intensity.

[0041] like Figure 1 As shown, a grille 103 is rotatably provided at the bottom of the box 101, and a water collecting trough 104 is provided between the bottom of the box 101 and the slide 204. When the grille 103 is attached to the bottom surface of the box 101, it can prevent the garbage in the box 101 from falling. The squeezing mechanism 300 can compact the garbage in the box 101 and separate the sewage therein. The water collecting trough 104 can collect the separated sewage, thereby realizing the preliminary drying of the garbage and improving the drying efficiency.

[0042] like Figure 1 , 5 As shown, the water collection tank 104 is slidably arranged on the water tank bracket 105, and the water tank bracket 105 can be fixed on the ground. When the grille 103 is away from the box body 101, it can drive the water collection tank 104 to slide, so that the water collection tank 104 is away from the bottom of the box body 101, so that the garbage falls onto the slide 204, thereby improving the level of automation.

[0043] like Figure 2 As shown, the drying drum 201 is tilted, with the outlet lower than the inlet, and a plurality of ventilation holes are provided on the drying drum 201. A drain trough 205 is fixed on the drum bracket 202, and the drain trough 205 is provided below the drying drum 201. The ventilation holes can improve the drying efficiency of the drying drum 201. Due to the presence of the ventilation holes, sewage in the garbage will flow out from the ventilation holes into the drain trough 205, and the drain trough 205 can conveniently collect sewage.

[0044] like Figure 2 , 3 As shown, an outer gear ring 207 is coaxially fixed on the drying drum 201, and the outer gear ring 207 is meshingly connected with a drum gear 208. The drum gear 208 is driven by a drum motor 206. The drum motor 206 is fixed on the drum bracket 202. The drum motor 206 can drive the drum gear 208 to rotate, and then drive the outer gear ring 207 to rotate, thereby driving the drying drum 201 to rotate.

[0045] like Figure 6As shown, the extrusion mechanism 300 includes a plurality of extrusion plates 301, four extrusion links 302 are connected between every two extrusion plates 301, and the end point of any extrusion link 302 is rotatably provided with the end point of another extrusion link 302. The four extrusion links 302 are connected in sequence to form a rhombus, and the two extrusion links 302 on the left are rotatably provided at their connection points on the extrusion plate 301 on the left, and the two extrusion links 302 on the right are rotatably provided at their connection points on the extrusion plate 301 on the right. For two adjacent rhombuses, the extrusion link 302 on the upper right of the left rhombus and the extrusion link 302 on the lower left of the right rhombus are fixed to each other and are on the same straight line, and the extrusion link 302 on the lower right of the left rhombus and the extrusion link 302 on the upper left of the right rhombus are fixed to each other and are on the same straight line.

[0046] The leftmost or rightmost extrusion plate 301 is fixed to the side of the box body 101, and the other extrusion plates 301 are slidably arranged in the box body 101. The extrusion plate 301 farthest from the extrusion plate 301 fixed to the side of the box body 101 is fixed to the telescopic end of the extrusion hydraulic cylinder 303 and driven by the extrusion hydraulic cylinder 303. The extrusion hydraulic cylinder 303 is fixed to the box body 101. The extension of the extrusion hydraulic cylinder 303 can drive the extrusion plate 301 fixed thereto to move, so that the extrusion plate 301 fixed to the extrusion hydraulic cylinder 303 and the extrusion plate 301 fixed to the side of the box body 101 are connected. 01 is shortened, thereby driving the rhombus formed by the squeezing connecting rod 302 to deform, and the distance between the left connection point and the right connection point of each rhombus is shortened, thereby driving and squeezing the squeezing plate 301 fixed by the hydraulic cylinder 303 and the squeezing plate 301 fixed on the side of the box body 101 to move, so that the garbage between the multiple squeezing plates 301 is compressed and the sewage therein is separated. Since the multiple squeezing plates 301 separate the garbage, when the garbage is squeezed, the force on the garbage is more uniform, the compression effect is better, and the drying efficiency is improved.

[0047] like Figure 4 As shown, a garbage input slope 106 is fixed on the top of the box 101, and a baffle 107 is fixed on the inclined surface of the garbage input slope 106. The baffle 107 is in a herringbone shape, and the baffle 107 can disperse the garbage to both sides of the baffle 107. The baffle 107 cooperates with the garbage input slope 106 to achieve a better garbage dispersion effect, and can make the garbage enter the box 101 more evenly, which helps to improve the drying efficiency of the extrusion mechanism 300.

[0048] like Figure 7 , 8As shown in Figures 9 and 10, the garbage hopper 400 includes a shell 401, a base 402 and a swinging groove 403. The base 402 is fixed on the lifting platform of the lift 102. The swinging groove 403 is rotatably provided on the base 402. The shell 401 is slidably provided in the swinging groove 403. The upper end of the dumping link 404 is rotatably provided on the shell 401, and the lower end of the dumping link 404 is rotatably provided on the base 402. In this embodiment, the clockwise rotation of the dumping link 404 can drive the shell 401 to move, and then drive the swinging groove 403 to rotate clockwise, so that the shell 401 slides downward while dumping garbage, and then the shell 401 is on the inclined surface of the garbage input slope 106 that can penetrate into the box 101 when dumping garbage, which reduces the garbage overflow when the garbage hopper 400 dumps garbage and reduces the labor burden.

[0049] like Fig.10 As shown, one end of the middle connecting rod 405 is coaxially fixed to the lower end of the dumping connecting rod 404, and the other end of the middle connecting rod 405 is rotatably provided with one end of the dumping hydraulic cylinder 406, and the other end of the dumping hydraulic cylinder 406 is rotatably provided on the base 402. The extension and retraction of the dumping hydraulic cylinder 406 can drive the rotation of the middle connecting rod 405, and then drive the rotation of the dumping connecting rod 404.

[0050] like Figure 7 , 8 As shown, a garbage door 407 is rotatably provided on the side of the housing 401, and the garbage door 407 is driven by a door opening mechanism. Figure 7 The state shown is that the garbage door 407 of the garbage bin 400 is open and the garbage is being dumped. Figure 8 The state shown is that the garbage door 407 of the garbage bin 400 is closed and garbage is being stored. In this embodiment, the garbage door 407 will return to the housing 401 after closing, so the garbage door 407 is in the Figure 8 The door opening mechanism includes an A link 408 and a B link 409. The lower end of the A link 408 is rotatably arranged on the housing 401. The upper end of the A link 408 is rotatably arranged with the upper end of the B link 409. The lower end of the B link 409 is rotatably arranged on the swing groove 403. An input sprocket is coaxially fixed to the lower end of the A link 408. An output sprocket is coaxially fixed to the garbage door 407. The input sprocket and the output sprocket are connected by a roller chain 410. Since the movement of the housing 401 can be decomposed into a rotational movement with the swing Due to the rotation of the movable groove 403 and the relative sliding with the swing groove 403, when the shell 401 moves, the distance between the lower end of the A connecting rod 408 and the lower end of the B connecting rod 409 will change, thereby driving the A connecting rod 408 to rotate, thereby driving the input sprocket to rotate, and then driving the output sprocket to rotate through the roller chain 410, and then driving the garbage door 407 to rotate, so that the shell 401 can automatically open the garbage door 407 while dumping garbage, which is convenient for driving and controlling the garbage door 407 and improving the level of automation.

[0051] like Figure 5 , 11 As shown in 14, the inner end point of the driving rod 501 is fixed at the inner end point of the grille 103, the rotation radius of the grille 103 is equal to the length of the driving rod 501, and the roller 502 is rotatably arranged at the outer end point of the driving rod 501. The plane where the top surface of the water collecting tank 104 is located is called the middle plane. The position of the grille 103 when it is attached to the bottom surface of the box body 101 is called the initial position of the grille 103. The swing angle when the grille 103 swings from the initial position to the position where the outer end point of the grille 103 contacts the middle plane is called the first swing angle. A driven block 503 is fixed on the side of the water collecting tank 104. The driven block 503 is provided with a driven groove. The roller 502 is slidably arranged in the driven groove. The top of the driven groove is open. After the grille 103 passes through the first swing angle, the roller 502 is separated from the driven groove. The distance that the water collecting tank 104 moves in the direction away from the bottom of the box body 101 is called H. 1 .

[0052] In this embodiment, when the grille 103 is at the first swing angle, when the grille 103 rotates downward at an angular velocity ω, it can drive the driving rod 501 to rotate, thereby driving the roller 502 to roll in the driven groove, thereby driving the driven block 503 to slide, thereby driving the water collection tank 104 to move, and the grille 103 is at the first swing angle. Fig.12 When the grille 103 is in the middle position, the value of θ at this time is the first swing angle of the grille 103, and R represents the length of the grille 103 and the driving rod 501. The outer end point of the grille 103 vertically descends at a speed of ωRcosθ, and the water collecting trough 104 moves horizontally to the left at a speed of ωRcosθ, which can avoid the grille 103 from colliding with the water collecting trough 104 during the swinging within the first swing angle range.

[0053] like Fig.12 , 13 As shown, the position where the grille 103 is perpendicular to the middle plane is called the end position of the grille 103, and the swing angle of the grille 103 from the position where the outer end point of the grille 103 contacts the middle plane to the end position of the grille 103 is called the second swing angle, and the second swing angle has a total of β radians. An arc-shaped rack 504 is fixed on the grille 103, and the center of the arc-shaped rack 504 coincides with the inner end point of the grille 103. The size of the center angle of the arc-shaped rack 504 is equal to β radians, and the arc length of the arc-shaped rack 504 is L. The arc-shaped rack 504 is meshed with an A gear 505, and the A gear 505 is rotatably set on a gear bracket 507. The A gear 505 is coaxially fixed with a B gear 506, and the gear bracket 507 is fixed on the water tank bracket 105. The B gear 506 is meshed with a spur rack 508, and the spur rack 508 is fixed on the water tank 104. The water tank 104 moves a distance H in the direction away from the bottom of the box body 101. 1 Then, it continues to move away from the bottom of the box 101 by a distance H. 2The water collecting tank 104 is completely misaligned with the bottom of the box body 101, and the radius ratio of the A gear 505 and the B gear 506 is equal to The distance from the middle plane to the bottom surface of the grid 103 when it is in the initial position is called h, and the value range of h is 0 to between.

[0054] In this embodiment, when the grille 103 is in the second swing angle range, when the grille 103 rotates downward at an angular velocity ω, it can drive the arc-shaped rack 504 to rotate, thereby driving the A gear 505 to rotate at an angular velocity of ω. The angular velocity of ω drives the gear B 506 to rotate, and then drives the spur rack 508 and the water collection tank 104 to rotate. The speed of the grid 103 is ω, and the time it takes for the grid 103 to rotate through β radians is , so when the grille 103 reaches the end position, the sump 104 continues to move away from the bottom of the box 101 by a distance H 2 The water collecting tank 104 is completely misaligned with the bottom of the box 101. When the grille 103 is swinging within the second swing angle range, the grille 103 intersects with the middle plane at a moving point. Since the horizontal speed of the moving point is equal to ωh, in order to avoid the collision between the moving point and the water collecting tank 104, the value range of h needs to be between 0 and between.

[0055] Through the cooperation of the driving rod 501, the driven block 503 and the arc-shaped rack 504, the grille 103 can drive the water collecting tank 104 to move while rotating downward and avoid collision between the grille 103 and the water collecting tank 104, so as to facilitate driving and controlling the grille 103 and the water collecting tank 104.

[0056] like Figure 5 As shown, one end of a driving hydraulic cylinder 509 is rotatably disposed on the driving rod 501 , and the other end of the driving hydraulic cylinder 509 is rotatably disposed on the box body 101 . The extension and retraction of the driving hydraulic cylinder 509 can drive the driving rod 501 to rotate.

[0057] Working process: the lifter 102 can raise the garbage bucket 400, and then the shortening of the dumping hydraulic cylinder 406 can drive the rotation of the middle connecting rod 405, and then drive the rotation of the dumping connecting rod 404. The clockwise rotation of the dumping connecting rod 404 can drive the shell 401 to move, and then drive the swing slot 403 to rotate clockwise, so that the shell 401 slides downward while dumping the garbage.

[0058] Since the movement of the shell 401 can be decomposed into the rotation along with the swing groove 403 and the relative sliding with the swing groove 403, when the shell 401 moves, the distance between the lower end of the A connecting rod 408 and the lower end of the B connecting rod 409 will change, thereby driving the A connecting rod 408 to rotate, thereby driving the input sprocket to rotate, and then driving the output sprocket to rotate through the roller chain 410, and then driving the garbage door 407 to rotate, so that the shell 401 can automatically open the garbage door 407 while dumping the garbage, so that the garbage can enter the box body 101 from the garbage input ramp 106.

[0059] After the garbage enters the box 101, the grille 103 sticks to the bottom surface of the box 101 to prevent the garbage in the box 101 from falling. Then the extrusion hydraulic cylinder 303 extends to drive the extrusion plate 301 fixed thereto to move, so that the distance between the extrusion plate 301 fixed to the extrusion hydraulic cylinder 303 and the extrusion plate 301 fixed to the side of the box 101 is shortened, thereby driving the rhombus formed by the extrusion connecting rod 302 to deform, and the distance between the left connection point and the right connection point of each rhombus is shortened, thereby driving the extrusion plate 301 fixed to the extrusion hydraulic cylinder 303 and the extrusion plate 301 fixed to the side of the box 101 to move, so that the garbage between the multiple extrusion plates 301 is compressed and the sewage therein is separated. The separated sewage flows into the sump 104 through the grille 103. The sump 104 can collect the separated sewage, thereby achieving preliminary drying of the garbage.

[0060] Subsequently, the hydraulic cylinder 509 is driven to shorten and drive the driving rod 501 to rotate, thereby driving the grille 103 to rotate downward. During the rotation of the driving rod 501, the driven block 503 is first driven to slide, thereby driving the water collection tank 104 to move. After the driving rod 501 is separated from the driven block 503, the arc rack 504 and the A gear 505 enter into a meshing state, and the arc rack 504 drives the A gear 505 to rotate, and then drives the B gear 506 to rotate, thereby driving the straight rack 508 to move, thereby driving the water collection tank 104 to move, so that the water collection tank 104 is completely misaligned with the bottom of the box body 101, and the bottom opening of the box body 101 is in an open state at this time.

[0061] Then, the squeezing mechanism 300 releases the garbage, and the garbage falls onto the slide 204 through the bottom opening of the box body 101, and then falls into the drying drum 201 through the slide 204. The drying drum 201 can turn the garbage and cooperate with the dryer 203 to further dry the garbage.
