The existing activated carbon granulation methods are mainly: extrusion molding, rolling granulation, spray drying granulation, tablet molding, hot melting (melt granulation), and wet granulation. In production practice, the activated carbon granulation method is selected according to the application scenario of the activated carbon granules to balance the particle strength, porosity, and production cost.

[0003] However, existing activated carbon granulation devices have difficulty classifying wood materials when mixing and stirring granulation materials. Using a uniform method to activate wood of different sizes can easily lead to high energy consumption or a lot of dust.

Guide blocks are connected to the outer side of the two baffles, and the baffles are slidably locked inside the mixing tank through the guide blocks.

[0009] Preferably, a stop block is provided inside the side hole, the top of the stop block is in contact with the bottom of the two baffles respectively, a connecting rope is connected to the top of the stop block, a fixing ring and an arc-shaped support plate are provided at the top of the mixing tank, the connecting rope is clamped on the arc-shaped support plate, and the two pull ropes are respectively passed through the two fixing rings.

[0012] Preferably, the inner cylinder is disposed inside the first spring, and a sealing ring is connected to the bottom end of the inner cylinder. The initial height of the top surface of the sealing ring is equal to the lowest point of the movement of the outer plate, and the outer side of the sealing ring is in contact with the inner wall of the mixing tank.

[0013] Preferably, a support is provided on the outside of the mixing tank, a telescopic rod is connected to the top of the support, a longitudinal rod is connected to the output end of the telescopic rod, and a sealing component is provided at the bottom end of the longitudinal rod.

[0014] Preferably, the sealing assembly includes a pair of crossbars at the bottom of the longitudinal rod, the two crossbars are arranged perpendicularly to each other on the horizontal plane, each crossbar has a pair of locking blocks slidably engaged, and each pair of adjacent locking blocks are connected by a sealing membrane, the outer side of the sealing membrane being connected to the inner side of the mixing tank.

[0015] Preferably, a motor is installed on the bottom wall of the mixing tank, and a rotating rod is coaxially connected to the output shaft of the motor.

[0016] The principle and beneficial effects of this technical solution:

[0017] (1) The screening component set in this invention can screen the granulation material poured into the mixing tank by size, so as to avoid the addition of materials with excessive size into the mixing tank for physical activation and increase the energy consumption of the device. After the granulation material enters the mixing tank, some wood chips with a size smaller than the screening hole on the guide plate will fall directly to the bottom of the mixing tank through the screening hole, while larger wood blocks will stay and accumulate on the guide plate. When a lot of wood blocks accumulate on the guide plate, the guide plate will gradually press down the first spring connected between it and the limiting ring until the bottom of the baffle plate is separated from the contact with the stop block, so that the stop block no longer blocks the inside of the side hole. At this time, the wood blocks will be guided by the guide plate and discharged to the outside of the device through the discharge pipe. After the wood blocks are discharged to the outside of the device, the stop block is manually reset, and the guide plate will be reset by the elastic force of the first spring.

[0018] (2) The sealing component provided in this invention can seal the lower side of the mixing tank during the mixing process. When it is necessary to stop wet mixing for material screening, the telescopic rod connected to the top of the support is extended. The extension of the telescopic rod will drive the longitudinal rod to move down, and the pair of crossbars at the bottom of the longitudinal rod will move down synchronously. When the crossbars move down, the locking blocks will move down synchronously. Since the adjacent locking blocks are connected by a sealing film, the sealing film will be stretched and the locking blocks will be pulled outward during the synchronous downward movement of the locking blocks, so that the screened wood chips can fall into the bottom of the mixing tank. When it is necessary to stir, the longitudinal rod can be driven to reset. Attached Figure Description

[0027] Example:

[0028] like Figures 1 to 6 As shown, the present invention provides an activated carbon material mixing and stirring device for activated carbon granulation, including a mixing tank 3 and a screening component.

A limiting ring 28 is fixedly connected to the inner wall of the mixing tank 3. The top end of the limiting ring 28 is connected to the bottom end of the guide plate 26 through a first spring 32. A side hole 19 is provided on the inner side wall of the mixing tank 3. An outlet pipe 1 is connected to the outer side of the mixing tank 3. One end of the outlet pipe 1 communicates with the side hole 19. A control component is provided on the outer side of the guide plate 26.

[0029] like Figure 5 and Figure 6 As shown, the control assembly includes a control block 22 connected to the outside of the guide plate 26, a groove 23 is provided on the inner wall of the outer side of the mixing tank 3, the control block 22 is slidably locked in the groove 23, and a control rope 21 is connected to the top of the control block 22.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, a pair of pull ropes 4 are connected to the top of the control rope 21, and two baffles 10 are connected to the bottom of the two pull ropes 4 respectively. Guide blocks 9 are connected to the outer side of the two baffles 10, and the baffles 10 are slidably locked inside the mixing tank 3 through the guide blocks 9.

[0031] like Figure 2 , Figure 3 and Figure 5As shown, a stop block 34 is provided inside the side hole 19. The top of the stop block 34 contacts the bottom of the two baffles 10 respectively. A connecting rope 6 is connected to the top of the stop block 34. A fixing ring 11 and an arc-shaped support plate 12 are provided at the top of the mixing tank 3. The connecting rope 6 is clamped on the arc-shaped support plate 12. Two pull ropes 4 are respectively threaded through the two fixing rings 11.

[0032] like Figure 1 and Figure 3 As shown, the free end of the connecting rope 6 is connected to the end plate 8, and the end plate 8 is connected to the second spring 7. The outer wall of the mixing tank 3 is provided with a side plate 13, and the free end of the second spring 7 is connected to the bottom end of the side plate 13.

[0033] like Figure 1 and Figure 6 As shown, the bottom end of the guide plate 26 is connected to the inner cylinder 30 and the outer plate 27. The bottom end of the outer plate 27 is connected to the retaining ring 29. The outer plate 27 is slidably locked inside the mixing tank 3. The inner diameter of the retaining ring 29 is smaller than the outer diameter of the limiting ring 28.

[0034] like Figure 1 and Figure 6 As shown, the inner cylinder 30 is located inside the first spring 32, and a sealing ring 31 is connected to the bottom end of the inner cylinder 30. The initial height of the top surface of the sealing ring 31 is the same as the lowest point of the movement of the outer plate 27, and the outer side of the sealing ring 31 is in contact with the inner wall of the mixing tank 3.

[0035] like Figures 1 to 4 As shown, a support 5 is provided on the outside of the mixing tank 3. A telescopic rod 14 is connected to the top of the support 5. A longitudinal rod 15 is connected to the output end of the telescopic rod 14. A sealing component is provided at the bottom of the longitudinal rod 15.

[0036] like Figure 1 and Figure 4 As shown, the sealing assembly includes a pair of horizontal bars 16 at the bottom of the vertical bar 15. The two horizontal bars 16 are arranged perpendicularly to each other on the horizontal plane. Each horizontal bar 16 is slidably fitted with a pair of locking blocks 17. Each pair of adjacent locking blocks 17 are connected by a sealing membrane 18. The outer side of the sealing membrane 18 is connected to the inner side of the mixing tank 3.

[0037] like Figure 1 , Figure 2 and Figure 5 As shown, a motor is installed on the bottom wall of the mixing tank 3. A rotating rod 20 is coaxially connected to the output shaft of the motor. A stirring blade 25 is connected to the outside of the rotating rod 20. The outer diameter of the stirring blade 25 is smaller than the inner diameter of the mixing tank 3. A side window 33 is opened on the outside of the mixing tank 3. A cover plate 2 is hinged to each side of the side window 33. A connecting pipe 24 is connected to the outside of the mixing tank 3.

[0038] The sealing assembly can seal the lower side of the mixing tank 3 during the mixing process. When it is necessary to stop wet mixing for material screening, the telescopic rod 14 connected to the top of the support 5 is extended. The extension of the telescopic rod 14 will drive the longitudinal rod 15 to move down, causing the pair of crossbars 16 at the bottom of the longitudinal rod 15 to move down synchronously. When the crossbars 16 move down, the locking blocks 17 will move down synchronously. Since the adjacent locking blocks 17 are connected by the sealing membrane 18, the sealing membrane 18 will be stretched during the synchronous downward movement of the locking blocks 17 and will pull the locking blocks 17 outward to slide, so that the screened wood chips can fall into the bottom of the mixing tank 3. When mixing is required, the longitudinal rod 15 can be driven to return to its original position.

[0039] The specific usage and function of this embodiment are as follows:

[0040] The screening component in this invention can screen the granulation material poured into the mixing tank 3 by size, preventing excessively large materials from being added to the mixing tank 3 for physical activation, thus increasing the energy consumption of the device. After the granulation material enters the mixing tank 3, some wood chips smaller than the screening holes on the guide plate 26 will fall directly to the bottom of the mixing tank 3 through the screening holes, while larger wood blocks will stay and accumulate on the guide plate 26. When a large number of wood blocks accumulate on the guide plate 26, the guide plate 26 will gradually press down on the first spring 32 connected to the limiting ring 28. During the downward movement of the guide plate 26, the control block 22 connected to the outside of the guide plate 26 slides along the slide groove 23, and at the same time, the control tube will pull the control rope 21 connected to its top. When the control rope 21 is pulled down, the two pull ropes 4 connected to its top will simultaneously pull the two baffles 10 to slide along the inside of the mixing tank 3 until the bottom of the baffle 10 is separated from the block. Since the top of the block is connected to the connecting rope 6, the end plate 8 connected to the free end of the connecting rope 6 is connected to the side plate 13 set on the outer wall of the mixing tank 3 through the second spring 7. Therefore, the elastic force of the second spring 7 will press down the end plate 8 connected to the free end of the connecting rope 6, so that the connecting rope 6 pulls the block up and the block no longer blocks the inside of the side hole 19. At this time, the wood block will be guided by the guide plate 26 and discharged to the outside of the device through the discharge pipe 1. After the wood block is discharged to the outside of the device, the block is manually reset, and the guide plate 26 will be reset by the elastic force of the first spring 32.

[0041] The inner cylinder 30 and outer plate 27 at the bottom of the guide plate 26 can control the stroke of the guide plate 26 through the retaining ring 29 and sealing ring 31 respectively, to prevent the guide plate 26 from moving to too low a position. At the same time, it can divide the mixing tank 3 into sections to prevent the screening part and the mixing part from being directly connected.

[0042] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
