Description

Technical Field

[0001] This utility model relates to the technical field of activated carbon production equipment, and in particular to a steam spray uniform distribution device for activated carbon production. Background Technology

[0002] Activated carbon, as an excellent adsorbent material, is widely used in many fields such as chemical engineering, environmental protection, and medicine. The key step in its production process is activation, which involves using activating agents such as water vapor to react with carbonaceous raw materials at high temperatures to form a well-developed pore structure and increase the specific surface area, thereby obtaining excellent adsorption performance.

[0003] During the activation process, a steam spraying device is typically used to introduce high-temperature steam into the charcoal-gas integrated machine or activation furnace. Existing steam spraying devices generally include steam pipes and several nozzles fixed on the pipes. These nozzles directly spray steam onto the raw material layer to achieve contact reaction between the raw materials and the activation gas.

[0004] However, in actual production, it has been found that the spray range of steam is greatly limited because the position and direction of the nozzles are fixed. This results in extremely uneven steam distribution across the vast raw material layer, easily leading to situations where some areas have excessive steam supply while others have insufficient supply. In areas with insufficient steam supply, the raw material is not fully activated, resulting in poor product adsorption performance; while in areas with excessive steam, over-activation may occur, damaging the already formed pore structure and also affecting product quality. This uneven spraying has become a major technical bottleneck restricting the improvement of the overall quality and production yield of activated carbon products.

[0005] Therefore, this utility model proposes a steam spray uniform distribution device for activated carbon production to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of fixed spray direction and uneven steam distribution in the existing steam spray uniform distribution device for activated carbon production, which affect the activation quality of activated carbon products, this utility model aims to provide a steam spray uniform distribution device for activated carbon production with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a steam spray uniform distribution device for activated carbon production, comprising: a base plate, a support frame fixedly connected to the top of the base plate, a carbon-gas integrated machine installed on the support frame, and a steam pipe arranged horizontally inside the carbon-gas integrated machine; and a reciprocating mechanism arranged on the outer wall of the steam pipe.

[0008] The reciprocating mechanism includes a mounting plate fixed to the outer wall of the steam pipe, a support plate fixed to the mounting plate, and a motor mounted on the support plate. A transmission rod is rotatably connected to the output end of the motor, and the end of the transmission rod is rotatably connected to a rotating plate via a connecting plate. A connecting rod is eccentrically rotatably connected to the rotating plate, and the other end of the connecting rod is slidably connected to a connecting plate of the adjusting assembly. Two fixed rods are rotatably connected to the connecting plate, and these fixed rods pass through the wall of the steam pipe and are fixedly connected to a nozzle installed inside the steam pipe. This transmission structure converts the rotational motion of the motor into the reciprocating oscillating motion of the nozzle.

[0009] Preferably, the steam spray uniform distribution device for activated carbon production further includes a filter mechanism installed on the inner wall of the steam pipe, the filter mechanism including a detachable filter screen.

[0010] Preferably, the filtering mechanism includes an actuation component, which includes a connecting rod 2 with a push plate at one end, and an inclined block is fixed on the connecting rod 2.

[0011] Preferably, the actuating component further includes a guide rod and a spring sleeved on the outer wall of the guide rod, one end of the guide rod being slidably connected to the rear end of the inclined block.

[0012] Preferably, the filtration mechanism further includes a detachable filter assembly, which includes a fixing rod two to which the filter screen is fixed.

[0013] Preferably, the filter assembly further includes a sliding plate fixedly connected to the second fixed rod, the sliding plate being slidably sleeved on the second guide rod.

[0014] Preferably, the inclined surface of the inclined block of the actuating component can detachably abut against the outer wall of the fixing rod 2 of the filter component to axially limit the filter component.

[0015] Preferably, a second spring is provided between the sliding plate of the filter assembly and the inner wall of the steam pipe, which is used to push the filter assembly out when the inclined block separates from the second fixing rod.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting up a reciprocating mechanism, utilizes the linkage of the motor-driven transmission rod, rotating plate and connecting rod to ultimately drive the nozzle to reciprocate and swing spray, which solves the problems of uneven steam spraying and insufficient or uneven activation of raw materials caused by the use of fixed nozzles in the prior art. It achieves the technical effect of making the steam evenly distributed over a large area in the carbon-gas integrated machine, thereby ensuring that the raw materials and steam are in full and balanced contact, and significantly improving the activation efficiency of activated carbon and product quality.

[0017] 2. This utility model, by setting a filter mechanism consisting of a push plate, inclined block, guide rod and spring in the steam pipe, realizes the quick installation and locking of the filter screen and convenient pop-out replacement. It solves the problems of easy clogging of the nozzle by steam impurities in the prior art, and the complex structure, inconvenient disassembly and maintenance, and time and labor consumption of the filter device. It achieves the technical effect of ensuring the cleanliness of steam, preventing nozzle clogging, greatly simplifying maintenance operations, shortening downtime, and improving the stability of equipment operation and production continuity.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1 to 6 This utility model provides a steam spray uniform distribution device for activated carbon production, which aims to solve the problems of low activation efficiency caused by uneven steam spraying and inconvenient disassembly and assembly of filter devices in the prior art.

[0022] like Figure 1 and Figure 2 As shown, the steam spray uniform distribution device for activated carbon production includes a base plate 1 and a support frame 2 fixedly connected to the top of the base plate 1. A carbon-gas integrated machine 3 is installed on the support frame 2. A steam pipe 4 is arranged horizontally inside the carbon-gas integrated machine 3. A reciprocating mechanism 5 is provided on the outer wall of the steam pipe 4, and a filter mechanism 6 is installed on the inner wall of the steam pipe 4. The reciprocating mechanism 5 includes an installation plate 51 fixed to the outer wall of the steam pipe 4. A support plate 52 is fixed on the installation plate 51. A motor 53 is installed on the support plate 52. The output end of the motor 53 is rotatably connected to a transmission rod 54. The end of the transmission rod 54 is rotatably connected to a rotating plate 56 through a connecting plate 55. A connecting rod 57 is eccentrically rotatably connected to the rotating plate 56. The other end of the connecting rod 57 is slidably connected to a connecting plate 581 of the adjusting component 58. Two fixing rods 582 are rotatably connected to the connecting plate 581. The fixing rods 582 pass through the pipe wall of the steam pipe 4 and are fixedly connected to a nozzle 583 set in the steam pipe 4.

[0023] To achieve uniform steam spraying, the core of the technical solution in this embodiment lies in the precision transmission design of the reciprocating mechanism 5. Please refer to the following for details. Figure 1 , Figure 3 and Figure 4The core structure is described in detail below: Mounting plate 51 serves as the mounting base for the reciprocating mechanism 5, and is fixed to the outer wall of the steam pipe 4 by welding or bolting. The integrally formed support plate 52 at the top of mounting plate 51 provides a stable mounting surface for motor 53. The output end of motor 53 is rotatably connected to one end of transmission rod 54 via a coupling. The other end of transmission rod 54 is rotatably connected to the center of rotating plate 56 via connecting plate 55 fixed thereon. After motor 53 starts, its rotational motion is sequentially transmitted to transmission rod 54 and rotating plate 56, causing rotating plate 56 to rotate around its central axis. On the surface of rotating plate 56, one end of connecting rod 57 is rotatably connected at a position offset from its rotation center. The other end of the connecting rod 57 is slidably connected to the inner wall of the connecting plate 581 in the adjusting assembly 58. This eccentric connecting rod structure cleverly converts the rotational motion of the rotating plate 56 into the reciprocating swing motion of the connecting rod 57. The outer wall of the connecting plate 581 is rotatably connected to two symmetrically arranged fixed rods 582. The fixed rods 582 pass through the pre-reserved through holes on the wall of the steam pipe 4 and are sealed. The end of the fixed rod that extends into the steam pipe 4 is fixedly connected to the nozzle 583. When the connecting rod 57 swings, it drives the connecting plate 581 and the fixed rod 582 to swing synchronously, and finally drives the nozzle 583 to reciprocate and spray in the steam pipe 4, ensuring that the steam can evenly cover the material inside the charcoal gas integrated machine 3.

[0024] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to ensure the purity of the steam entering the nozzle 583 and prevent impurities from clogging it, please refer to... Figure 5 and Figure 6A filter mechanism 6 is installed on the inner wall of the steam pipe 4. The filter mechanism 6 includes a detachable filter screen 609, which is used to filter solid particulate impurities in the steam. Further, to facilitate the installation and removal of the filter screen 609, the filter mechanism 6 includes an operating component. This component includes a connecting rod 602 with a push plate 601 at one end. A wedge 603 is fixed to the connecting rod 602. The push plate 601 is exposed outside the steam pipe 4 for easy manual operation. To enable the operating component to automatically reset after operation, the component also includes a guide rod 604 and a spring 605 sleeved on the outer wall of the guide rod 604. One end of the guide rod 604 is slidably connected to the rear end of the wedge 603, while the other end is fixed to the inner wall of the steam pipe 4. The two ends of the spring 605 abut against the wedge 603 and the inner wall of the steam pipe 4, respectively, to provide guidance and resetting force when the push plate 601 resets. In addition, the filter mechanism 6 also includes a detachable filter assembly for supporting the filter screen 609. The filter assembly includes a fixing rod 610 fixed to the filter screen 609. To achieve stable installation and quick ejection of the filter assembly, the filter assembly also includes a sliding plate 608 fixedly connected to the fixing rod 610. The sliding plate 608 is slidably sleeved on the guide rod 606, which is fixed to its inner wall parallel to the axis of the steam pipe 4. A spring 607 is provided between the sliding plate 608 and the inner wall of the steam pipe 4. In the installed state, the inclined surface of the inclined block 603 detachably abuts against the outer wall of the fixing rod 610 to axially limit the filter assembly. During disassembly, the spring 607 is used to push the filter assembly to eject.

[0025] The implementation principle of this application embodiment is as follows: When it is necessary to spray steam inside the charcoal and gas integrated machine 3, the motor 53 installed on the support plate 52 is started. The motor 53 drives the transmission rod 54 to rotate. The transmission rod 54 drives the rotating plate 56 to rotate synchronously through the connecting plate 1 55. Since one end of the connecting rod 1 57 is eccentrically connected to the rotating plate 56, the rotation of the rotating plate 56 will drive the other end of the connecting rod 1 57 to slide on the inner wall of the connecting plate 2 581 of the adjustment component 58, thereby causing the connecting plate 2 581 to swing back and forth. The swing of the connecting plate 2 581 is transmitted to the nozzle 583 through the fixing rod 1 582, so that the nozzle 583 can perform a back-and-forth swinging uniform spraying inside the steam pipe 4 to different areas inside the charcoal and gas integrated machine 3, which solves the problem of poor activation effect caused by uneven spraying.

[0026] Before steam enters the nozzle 583, it passes through the filter mechanism 6. When the filter screen 609 needs to be installed, the push plate 601 is pushed inward. The push plate 601 moves the fixed connecting rod 602 and the inclined block 603. The inclined block 603 compresses the spring 605, causing it to contract. At the same time, the filter assembly to be installed, its fixed rod 610 drives the sliding plate 608 to slide along the guide rod 606 and compress the spring 607 until the filter screen 609 reaches the designated filtration position. Then the push plate 601 is released, and the spring 605 rebounds, causing the push plate 601 to return to its original position. At this time, the inclined block 603 and the fixed rod 610 abut and lock. When the filter screen 609 needs to be replaced, the push plate 601 is pushed again, causing the inclined block 603 to move and separate from the fixed rod 610, releasing the lock. At this time, the compressed spring 607 immediately rebounds, pushing the sliding plate 608, the fixed rod 610, and the filter screen 609 to automatically pop out as a whole, realizing the convenient installation and removal of the filter screen 609.
