Description

Technical Field

[0001] The utility model belongs to the technical field of cyclone dust collectors, and particularly relates to a powder connecting device for a cyclone dust collector that can be recycled. Background Art

[0002] A cyclone dust collector is a type of dust removal device. Its dust removal mechanism is to make the dust-laden airflow rotate, using centrifugal force to separate dust particles from the airflow and capture them on the wall of the device. Gravity then causes the dust particles to fall into the ash hopper. During the use of the cyclone dust collector, it is necessary to connect the cyclone dust collector to the reactor through a connecting device to ensure that the cyclone dust collector can effectively recover iron oxide balls and realize resource recycling.

[0003] Upon investigation, the publication (announcement) number CN213762368U discloses a cyclone dust collector powder recycling device. This technology discloses "including a dust collector body, the bottom end of the dust collector body is connected to a storage device, the storage device includes a storage box fixedly connected to the discharge end of the dust collector body, and the interior of the storage box is fixedly connected to a conical screen. The technical solution has the function of collecting dust and particles collected by the dust collector body, and under the action of the screen, the particles and dust can be effectively separated. By setting an induced draft phase, the dust inside the storage box can be effectively extracted, achieving the purpose of automatic dust recovery and reuse. The device not only effectively separates materials, but also saves manpower and other technical effects."

[0004] When in use, the above design can effectively extract the dust inside the storage box and achieve the purpose of automatic dust recovery and reuse. However, the current cyclone dust collector separates the dust and HCL of the iron oxide balls that react at high temperature. After separation, some of the iron oxide balls will pass through the lower pipe of the cyclone dust collector and remain in the hopper, exposed to the air, causing the iron oxide balls to undergo high-temperature reaction. Due to the extremely high temperature, if the staff touches them, they will easily get burned, and in severe cases, they may be life-threatening. The flap valve composed of the two valve groups always has one valve in the closed state, which ensures the stable pressure difference on the reactor side and the safety of the working environment.

[0005] In order to solve the above problems, the present application proposes a cyclone dust collector powder connection device that can be recycled. Utility Model Content

[0026] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figure 1 As shown:

[0029] A cyclone dust collector powder connection device capable of recycling and utilizing the same comprises a reaction furnace 1 and a cyclone dust collector body 2 arranged on one side of the reaction furnace 1.

[0030] In this embodiment: the existing device {publication (announcement) number}: CN213762368U, discloses: a cyclone dust collector powder recycling device, this application makes further improvements on this existing subject, please refer to the disclosed technology below for details; in order to solve the technical problems existing in this existing technology, as disclosed in the background technology above, "although the design can effectively extract the dust inside the storage box and achieve the purpose of automatic dust recovery and reuse, the current cyclone dust collector separates the dust and HCL of the iron oxide balls that react at high temperature. After separation, some of the iron oxide balls will remain in the hopper through the lower pipe of the cyclone dust collector and be exposed to the air, causing the iron oxide balls to undergo high-temperature reaction and just turn from red to black. Due to the extremely high temperature, if the staff touches it, they will easily get burned, and in severe cases, their lives may be endangered." In terms of use, this problem is obviously a real and difficult problem to solve. In view of this, in order to solve this technical problem, a dust return component 3 and a control component 4 are added to this application document, and the electrical equipment involved in this product are all powered by an external power supply.

[0031] More specifically:

[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown:

[0033] A dust return assembly 3 is installed between the reactor 1 and the cyclone dust collector body 2. The dust return assembly 3 includes a dust return pipe 31 arranged between the reactor 1 and the cyclone dust collector body 2, a connecting pipe 35 arranged between the reactor 1 and the dust return pipe 31, and a first flap valve 32 and a second flap valve 33 fixed on the surface of the dust return pipe 31 and distributed upper and lower respectively.

[0034] In this embodiment: the recyclable cyclone dust collector powder connection device, when in use, first, during the process of separating the dust and HCL of the iron oxide balls in the reactor 1, some of the iron oxide balls will remain in the hopper through the lower pipe of the reactor 1 after separation, and will be discharged into the dust return pipe 31, and then discharged into the first flap valve 32 through the dust return pipe 31. When the motor rotates, the cam connected to the motor drives the first flap valve rocker and the second flap valve rocker to rotate, and the valve plate (not shown in the figure) inside the first flap valve 32 will rotate, so that a certain opening is generated between the valve plate and the first flap valve 32. At this time, the iron oxide balls enter the second flap valve 33. By repeating the above operation, the iron oxide balls will be discharged into the interior of the reactor 1 through the connecting pipe 35, and the iron oxide balls can be recovered, thereby realizing the recycling of resources and avoiding waste of resources. When it is necessary to control the time and temperature of the iron oxide balls returning to the reactor 1, through this operation, it is not easy for the iron oxide balls to come into contact with the staff, which greatly improves the safety of personnel operation. The recovery of iron oxide balls can greatly improve the allocation of manpower, and does not require manual disposal of iron oxide dust, and does not require long-term manual supervision, thus avoiding personal injuries caused by the operation of the unit. In addition, it occupies a small volume and can make good use of the space between the reactor 1 and the cyclone dust collector body 2, thereby improving space utilization.

[0035] It should be noted that: the valve plates of the first flap valve 32 and the second flap valve 33 are opened by the rocker arm driven by the cam connected to the motor. After the iron oxide ball falls, the motor drives the cam to continue to rotate, and the counterweight of the rocker arm automatically resets the valve plate, thereby completing the material transportation. By using the first flap valve 32 and the second flap valve 33, the main purpose is to use the opening and closing of the upper and lower valves at different times to ensure that there is always a valve plate in the middle of the equipment in a closed isolation state to prevent the formation of a pressure difference, ensure that the pressure difference will not be disturbed, and prevent the gas in the reactor from flowing, and the iron oxide ball flows back to the cyclone dust collector body 2 through the dust return pipe 31, affecting the production of the equipment.

[0036] In an optional embodiment, the cyclone dust collector body 2 and the dust return pipe 31 are connected through a first flange 34, the dust return pipe 31 and the first flap valve are connected through a second flange 39, the connecting pipe 35 and the second flap valve are connected through a third flange 36, and the end of the connecting pipe 35 away from the dust return pipe 31 is fixedly connected to the reactor 1.

[0037] In this embodiment: the cyclone dust collector body 2 and the dust return pipe 31 are fixedly connected by a first flange 34, the dust return pipe 31 and the first flap valve are fixedly connected by a second flange 39, and the connecting pipe 35 and the second flap valve are connected by a third flange 36.

[0038] In an optional embodiment, the four corners of the first flap valve 32 and the second flap valve 33 are connected by fastening bolts 311 , and clamps 37 are fixed to the surfaces of the first flange 34 , the second flange 39 , and the third flange 36 .

[0039] In this embodiment: the first flap valve 32 and the second flap valve 33 are fixedly connected by fastening bolts 311, which is convenient for later maintenance operations. The surfaces of the first flange 34 and the second flange 39 are fixed with clamps 37. The clamps 37 can increase the sealing performance of the connection between the first flange 34 and the second flange 36 to avoid air leakage.

[0040] In an optional embodiment, a fixing bracket 322 is fixed on the side of the reactor 1 surface close to the dust return pipe 31 , and a fixing plate 38 is fixed on the end of the fixing bracket 322 away from the reactor 1 . The fixing plate 38 is fixed on the surface of the first flap valve 32 .

[0041] In this embodiment, since the dust return pipe 31 carries the first flap valve 32 and the second flap valve 33 as well as the drive motor 42 , it is securely reinforced by the fixing bracket 322 and the fixing plate 38 to improve the stability.

[0042] Going further;

[0043] like Figure 1 and Figure 2 As shown:

[0044] The recyclable cyclone dust collector powder connection device also includes a control component 4, which includes a connecting plate 41 fixed to the surface of the first flap valve 32 and the second flap valve 33 on the side close to the reactor 1, a drive motor 42, and a cam 45 fixed to the output end of the drive motor 42. The cam 45 and the rocker arm 43 are in the same plane, and a protective pad 44 is bonded to the upper surface of the rocker arm 43.

[0045] In this embodiment: first, the motor 42 is started to drive the cam 45 to rotate, which in turn drives the rocker arm 43 to rotate at an angle, and the rocker arm 43 is used to respectively move the counterweight levers on the first flap valve 32 and the second flap valve 33, and the rotation of the counterweight lever drives the valve plates inside the first flap valve 32 and the second flap valve 33 to rotate, so that the iron oxide balls in the dust return pipe 31 enter the first flap valve 32, the second flap valve 33 and the inside of the reactor 1, so that the time and temperature of the iron oxide balls returning to the furnace can be effectively controlled according to one's own needs. This structure is simple and practical, and meets people's actual use needs. The protective pad 44 can protect the counterweight lever, and at the same time, the hitting noise of the rocker arm 43 can be reduced, thereby improving the use effect of the device.

[0046] It should be noted that the protective pad 44 is made of rubber, which has certain shock absorption and wear resistance characteristics. This structure is more practical.

[0047] The working principle and use process of the utility model: the recycling cyclone dust collector powder connection device, when in use, first, during the process of separating the dust and HCL of the iron oxide balls in the reactor 1, some of the iron oxide balls will remain in the hopper through the lower pipe of the reactor 1 after separation, and be discharged into the dust return pipe 31, and then be discharged into the first flap valve 32 through the dust return pipe 31. When the motor rotates, the cam connected to the motor drives the first flap valve rocker and the second flap valve rocker to rotate, and the valve plate (not shown in the figure) inside the first flap valve 32 will rotate, so that a certain opening is generated between the valve plate and the first flap valve 32, and the iron oxide balls enter the second flap valve 33. Repeat the above operation, and the iron oxide balls will be discharged into the reactor 1 through the connecting pipe 35, which can recycle the iron oxide balls, realize the recycling of resources, and avoid resource waste. When it is necessary to control the time and temperature of the iron oxide balls returning to the reactor 1, this operation is performed. , it is not easy for the iron oxide balls to contact the staff, greatly improving the safety of personnel operation and the recovery of iron oxide balls can greatly improve the manpower allocation, and there is no need for manual disposal of iron oxide dust, no need for long-term manual supervision, and avoids personal injury caused by the operation of the unit. It also occupies a small volume and can make good use of the space between the reactor 1 and the cyclone dust collector body 2, improving space utilization. First, start the motor 42 to drive the cam 45 to rotate and then drive the rocker arm 43 to rotate the angle. The rocker arm 43 is used to shift the counterweight lever on the first flap valve 32 and the second flap valve 33, thereby driving the valve plates inside the first flap valve 32 and the second flap valve 33 to rotate, so that the iron oxide balls in the return dust pipe 31 enter the first flap valve 32, the second flap valve 33 and the inside of the reactor 1, so that the time and temperature of the iron oxide balls returning to the furnace can be effectively controlled according to one's own needs. This structure is simple and practical, and meets people's actual use needs.
