DETAILED DESCRIPTION

[0034] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The following describes an embodiment of the present invention based on its overall structure.

[0036] See also Figures 1 to 10 , which is a preparation device of biological activated carbon for water ecological restoration provided by the present invention, includes a cylinder 1, a telescopic transmission rod 15, two sets of spiral rollers 2 arranged side by side, an end cover 3, an output rod 16, an extrusion head 4, a feed hopper 5, and two pressing impellers 6. The cylinder 1 is provided with a accommodating space, a first end and a second end. The first end is opened and connected to the accommodating space.

[0037] Among them, the cylinder 1 is the core shell of the preparation equipment, which accommodates other key components inside, providing a closed and stable working space for the preparation of biological activated carbon, ensuring that the preparation process is not disturbed by the outside world. The base frame 35 is located at the bottom of the cylinder 1, and plays a role in firmly supporting the cylinder 1 and the entire equipment, so that the equipment can be placed stably on the ground or on a workbench, providing a solid foundation for the normal operation of the equipment, and ensuring that the equipment will not affect the molding quality of the activated carbon due to shaking during the preparation process.

[0038] Two groups of spiral rollers 2 are located in the accommodation space of the cylinder 1. They cooperate with each other and realize rotation connection with the cylinder 1 through the rotating shaft. A transmission hole 34 is opened inside one group of rotating shafts for connecting the output shaft of the external driving motor to receive power. The outer sides of the two groups of rotating shafts are fixed with mutually meshing transmission gears 7 to ensure that the two groups of spiral rollers 2 can rotate synchronously in opposite directions. The end cover 3 is connected to the end of one side of the cylinder 1 and fits tightly with the cylinder 1. Support connection caps 31 that match the rotating shafts of the two groups of spiral rollers 2 are arranged at both ends of the end cover 3. When the equipment is operating normally, the connection cap 31 provides stable support for the rotating shaft of the spiral roller 2. The end cover 3 and the cylinder 1 are threadedly fastened by multiple groups of bolts 33 to ensure that the end cover 3 is tightly connected to the cylinder 1 to prevent leakage or loosening during the preparation process. Handles 32 are fixed at both ends of the end cover 3 to facilitate the staff to open and close the end cover 3 during inspection and maintenance.

[0039] When the external driving motor is started, the power is transmitted to one of the spiral rollers 2 through the transmission hole 34. Under the action of the transmission gear 7, the two spiral rollers 2 rotate synchronously in opposite directions. In the process of preparing activated carbon, the prepared carbonaceous material is added from the feed hopper 5. The material falls between the two spiral rollers 2 under the action of gravity. The rotation of the spiral rollers 2 produces an extrusion and pushing effect on the material, causing it to gradually move toward the end cover 3. In this process, the material is gradually compacted and forms a continuous carbon strip, which is finally extruded through the extrusion head 4 inside the end cover 3 to obtain an activated carbon strip of the desired shape. The design of the spiral rollers 2 can ensure that the material is evenly stressed and stably extruded, thereby improving the quality and production efficiency of the activated carbon strip.

[0040] The feed hopper 5 is fixed on one side of the top of the cylinder 1, and is connected to the cylinder 1 inside, providing an entrance for adding activated carbon raw materials. Both ends of the feed hopper 5 are rotatably connected with a press impeller 6, and the press impeller 6 and the feed hopper 5 are rotatably connected through a connecting shaft 8. A first synchronous wheel 11 is fixed on the outside of one set of connecting shafts 8, and the first synchronous wheel 11 and one side of the first transmission rod 10 are connected by a first synchronous belt 12. The two sets of connecting shafts 8 and the rotating shafts of the two sets of spiral rollers 2 are connected by a transmission belt 9, realizing the transmission and distribution of power;

[0041] When the spiral roller 2 rotates driven by an external driving motor, its power is transmitted to the connecting shaft 8 through the transmission belt 9, so that the connecting shaft 8 drives the pressing impeller 6 to rotate. Since the two groups of pressing impellers 6 rotate in opposite directions, they can force the activated carbon raw materials in the feed hopper 5 into between the two groups of spiral rollers 2. This forced feeding method can effectively avoid the accumulation or blockage of raw materials in the feed hopper 5, ensure that the raw materials stably and evenly enter the spiral roller 2 for extrusion molding, improve production efficiency, and ensure the molding quality of activated carbon strips. At the same time, through the transmission connection of the first synchronous wheel 11, the first synchronous belt 12 and the first transmission rod 10, the rotation of the pressing impeller 6 and the movement of the spiral roller 2 are coordinated with each other, further optimizing the entire feeding and extrusion molding process;

[0042] The first transmission rod 10 is rotatably connected to the top of the cylinder 1, and the end thereof is movably connected to the second transmission rod 13 through a universal joint 14, so as to realize a flexible connection between the two and adapt to the transmission requirements at different angles. A telescopic transmission rod 15 is arranged inside the second transmission rod 13, and the telescopic transmission rod 15 and the second transmission rod 13 are connected in a radially limited and axially sliding manner, so as to ensure that the telescopic transmission rod 15 can stably slide axially in the second transmission rod 13 and remain fixed in the radial direction;

[0043] An output rod 16 is fixed at the end of the telescopic transmission rod 15, and a second synchronous wheel 17 is movably connected to the top of the end cover 3. The second synchronous wheel 17 and the output rod 16 are connected by a second synchronous belt 18. Two groups of first support seats 28 fixed to the inner wall of the cooling cover 24 are arranged on the outside of the first transmission rod 10. A second support seat 29 and a third support seat 30 matched with the second transmission rod 13 and the output rod 16 are fixed inside the cooling channel 25. Bearings are arranged inside the first support seat 28 and the second support seat 29. The bottom of the third support seat 30 is fixedly connected to the top of the end cover 3. The arrangement of these support seats and bearings provides stable support for the rotation of the transmission rod, reduces the friction resistance during the rotation process, and ensures the smoothness of the transmission.

[0044] During the operation of the equipment, the rotational power of the connecting shaft 8 is transmitted to the first transmission rod 10 through the first synchronous belt 12, and the first transmission rod 10 transmits the power to the second transmission rod 13 by means of the universal joint 14, and the second transmission rod 13 drives the telescopic transmission rod 15 to rotate, and then the output rod 16 rotates synchronously, and the rotational power of the output rod 16 is transmitted to the second synchronous wheel 17 through the second synchronous belt 18, so that the second synchronous wheel 17 drives the cutting blade 19 to rotate. Since the cutting blade 19 is located at the end of the extruder head 4, when the activated carbon strip is extruded from the extruder head 4, the cutting blade 19 can cut it in sections;

[0045] The design of this transmission mechanism cleverly utilizes the driving power of the spiral roller 2, realizing the integrated operation of the extrusion molding and segmented cutting of the activated carbon strips, without the need to set up an additional power source for the cutting equipment, effectively reducing the equipment cost, saving energy, and at the same time reducing the space occupied by the equipment and improving production efficiency;

[0046] Specifically, the cutting blade 19 is fixed on the outside of the second synchronous wheel 17. When the second synchronous wheel 17 rotates under the drive of the transmission mechanism, the cutting blade 19 rotates at a high speed. Its sharp blade can accurately cut the extruded activated carbon strips into small segments of a predetermined length, ensuring that the size of the activated carbon strips meets the requirements of subsequent carbonization, activation and packaging processes. The position of the cutting blade 19 is close to the extrusion head 4, so that the cutting action can be carried out in a timely and efficient manner, avoiding the activated carbon strips being too long or irregular and affecting subsequent processing;

[0047] One side of one of the connecting shafts 8 is connected to a speed increasing module 22, and a fan impeller 23 is fixedly connected to the output end of the speed increasing module 22. A cooling cover 24 located outside the fan impeller 23 is provided at the top of the cylinder 1. Both ends of the cooling cover 24 are provided with multiple groups of air inlet holes 37. A cooling channel 25 located outside the first transmission rod 10 and the second transmission rod 13 is provided at the top of the cylinder 1. A connecting hose 26 located outside the universal joint 14 is connected between the cooling cover 24 and the cooling channel 25. A guide plate 27 is provided at the bottom of the end of the cooling channel 25.

[0048] When the equipment is running, the rotation of the connecting shaft 8 drives the fan impeller 23 to rotate at a high speed through the speed increasing module 22. The fan impeller 23 inhales external air from the air inlet 37. After the air enters the cooling cover 24, it enters the cooling channel 25 through the connecting hose 26, and finally blows to the extrusion head 4 under the guidance of the guide plate 27. The temperature of the newly extruded activated carbon strips is relatively high, and they are easy to stick to each other after cutting. The blowing of cooling air makes the activated carbon strips cool down quickly, avoiding the problem of sticking, effectively improving the molding quality and molding effect of the activated carbon strips after cutting, and ensuring that the activated carbon strips can maintain good shape and performance in the subsequent processing process;

[0049] The top of the support rod 20 is movably connected to the top of the cylinder 1, and the bottom is movably connected to a slider 21. A slide groove matching the slider 21 is provided inside the top of the cylinder 1. Both ends of the support rod 20 and the first transmission rod 10 and the slider 21 are movably connected through a hinge seat. This connection method enables the support rod 20 to flexibly rotate and extend within a certain range.

[0050] When the equipment is operating normally, the support rod 20 is in a retracted state and does not affect the work of other components. When the spiral roller 2 inside the cylinder 1 needs to be inspected and maintained, the staff opens the end cover 3. During the flipping process of the end cover 3, the end cover 3 drives the second transmission rod 13, the telescopic transmission rod 15, the output rod 16 and the cutting blade 19 to flip at the same time through the second support seat 29. The second transmission rod 13 flips relative to the first transmission rod 10 through the universal joint 14, and drives the support rod 20 to flip at the same time.

[0051] When the support rod 20 turns over, the slider 21 at its end slides in the slide groove at the top of the cylinder 1. When the end cover 3 is fully opened, the slider 21 slides to the end of the slide groove. At this time, the support rod 20 and the second transmission rod 13 form a triangular support structure, which plays a role in stabilizing the opened end cover 3, making it convenient for the staff to inspect and maintain the spiral roller 2 and clean the activated carbon raw materials remaining inside the end cover 3, thereby improving the maintenance convenience and work efficiency of the equipment.

[0052] The working principle of the present invention is as follows: when in use, the power is turned on, a transmission hole 34 is opened in the rotating shaft of one set of spiral rollers 2, and the transmission hole 34 is connected to the output shaft of the external driving motor, and then under the action of the external power supply device and the control module 36, the external driving motor can drive the two sets of spiral rollers 2 meshed with each other through the transmission gear 7 to rotate synchronously in the opposite direction inside the cylinder 1, so that the activated carbon raw material can be extruded and transported;

[0053] Specifically, the activated carbon raw material to be extruded into strips is transported into the feed hopper 5 through the external feeding equipment. At this time, the rotational power of the spiral roller 2 is transmitted to the two sets of connecting shafts 8 through the transmission belt 9. At this time, the two sets of rotating connecting shafts 8 drive the two sets of pressing impellers 6 located inside the feed hopper 5 to rotate in the opposite direction, thereby forcibly pressing the activated carbon raw material between the two sets of spiral rollers 2.

[0054] At this time, when the two sets of spiral rollers 2 rotate, the activated carbon raw material can be gradually pushed and extruded inside the cylinder 1, and then extruded through the extrusion head 4 inside the end cover 3, so that the activated carbon principle is extruded into an activated carbon strip structure;

[0055] Furthermore, when the device is running, the rotational power of the connecting shaft 8 is transmitted to the first transmission rod 10 through the first synchronous belt 12. At this time, the first transmission rod 10 drives the output rod 16 to rotate through the universal joint 14, the second transmission rod 13 and the telescopic transmission rod 15 in sequence. The rotational power of the output rod 16 is transmitted to the second synchronous wheel 17 through the second synchronous belt 18. At this time, the rotation of the second synchronous wheel 17 drives the cutting blade 19 to rotate;

[0056] Since the cutting blade 19 is located at the end of the extruder head 4, the rotation of the cutting blade 19 can cut the extruded activated carbon strips into sections. As can be seen from the above, a set of power equipment can not only complete the extrusion molding operation of the spiral roller 2 on the activated carbon raw material, but also force the activated carbon raw material to be fed through the pressing impeller 6, thereby ensuring the extrusion molding efficiency of the spiral roller 2. At the same time, through a series of transmissions, the cutting blade 19 can synchronously cut the activated carbon strips into sections.

[0057] As can be seen from the above, there is no need to add additional power equipment to cut the activated carbon strips, which effectively reduces the overall use cost and saves some energy. At the same time, the integrated design also effectively reduces the space occupied by the factory, and the use effect is better;

[0058] Furthermore, another set of connecting shafts 8 are connected to a fan impeller 23 at the end through a speed increasing module 22, wherein the fan impeller 23 is located inside a cooling cover 24, wherein the end of the cooling cover 24 is connected to a cooling channel 25 through a connecting hose 26, and the end of the cooling channel 25 extends all the way to the top of the extruder head 4, and a guide plate 27 is provided at the bottom of the cooling channel;

[0059] Then, the external air absorbed by the fan impeller 23 from the multiple groups of air inlet holes 37 can be blown toward the extrusion head 4 through the cooling cover 24, the connecting hose 26, the cooling channel 25 and the guide plate 27 in sequence, so that the activated carbon strips just extruded are cooled to a certain extent by the gas, thereby avoiding the problem of the activated carbon strips sticking to each other after being cut and stacked together, and effectively improving the molding quality and molding effect of the activated carbon strips after cutting;

[0060] After running for a period of time, the staff needs to inspect and maintain the spiral roller 2 inside the cylinder 1. At this time, the staff uses a tool to loosen the multiple sets of bolts 33 connecting the end cover 3 and the cylinder 1 to separate the end cover 3 and the cylinder 1 from each other;

[0061] At this time, the staff pulls the end cover 3 out parallel to the cylinder body 1 through the two sets of handles 32, and the two sets of supporting connecting caps 31 on the end cover 3 are separated from the support of the rotating shafts of the two sets of spiral rollers 2. At the same time, the telescopic transmission rod 15 extends relative to the second transmission rod 13, wherein the telescopic transmission rod 15 and the second transmission rod 13 are radially limited and axially slidably connected;

[0062] When the end cover 3 is pulled out in parallel to realize the shaft-off action, the staff then flips the end cover 3 upwards and opens it through the handle 32. When the end cover 3 flips, the second transmission rod 13, the telescopic transmission rod 15, the output rod 16 and the cutting blade 19 are simultaneously driven to flip through the third support seat 30. At this time, the second transmission rod 13 flips relative to the first transmission rod 10 through the universal joint 14.

[0063] That is to say, at this time, the flipping and opening of the end cover 3 and other components is performed by rotating along the universal joint 14. When the second transmission rod 13 is flipped and opened along with the end cover 3, the second transmission rod 13 drives the support rod 20 to flip, and when the support rod 20 flips, the slider 21 at the end of the support rod 20 and the cylinder 1 slide passively.

[0064] When the end cover 3 is completely opened, the slider 21 at the end of the support rod 20 slides to the end of the slide slot, so that the support rod 20 forms a supporting effect on the opened end cover 3;

[0065] Specifically, the two ends of the support rod 20 and the slider 21 and the second transmission rod 13 are rotatably connected through a hinge seat, wherein the end of the slide groove matched with the slider 21 is located on one side of the hinge seat between the support rod 20 and the second transmission rod 13, that is, at this time, the support rod 20 and the second transmission rod 13 after opening form a triangular support under the cooperation, thereby playing a role in stably supporting the end cover 3 after opening;

[0066] At this time, the staff can inspect and maintain the two sets of spiral rollers 2, and at the same time, the staff can clean the activated carbon raw materials remaining inside the end cover 3, which is convenient for the quality of the next activated carbon strip extrusion molding. The overall inspection and maintenance operation is relatively convenient, which improves the overall work efficiency;

[0067] Finally, when the inspection and maintenance are completed, the staff needs to close the end cover 3 and the cylinder 1. At this time, the staff first manually slides the slider 21 at the end of the support rod 20 inward, so that the slider 21 passes over the hinge seat point where the support rod 20 and the second transmission rod 13 are connected. At this time, with the closing of the end cover 3, the support rod 20 can be passively retracted into the groove at the top of the cylinder 1. When the end cover 3 is closed to a vertical state, the staff manually pushes the end cover 3 horizontally so that the two sets of support connecting caps 31 support the rotating shafts of the two sets of spiral rollers 2, and then connects and locks the end cover 3 and the cylinder 1 with each other through multiple sets of bolts 33.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
