Description

Technical Field

[0001] This invention relates to the field of cement production technology, and in particular to a dust removal device and its control method for cement production. Background Technology

[0002] Cement, formerly known as cementitious cementitious material, is a powdery hydraulic inorganic binder that forms a paste when mixed with water. It hardens in air or water and can firmly bind materials such as sand and stone together. Its raw materials include calcareous, clayey, and ferrous materials. Different proportions of raw materials directly affect the mineral composition ratio and main technical properties of cement clinker.

[0003] Currently, a large amount of dust is generated during the cement production process. This dust not only pollutes the environment but also poses certain harms to the human body. Therefore, dust removal devices are generally installed in cement production areas to remove dust.

[0004] The dust removal devices mentioned above are generally equipped with dust suction hoods, which are aimed at the cement production area to remove dust. However, the dust suction hoods are mostly fixed and tilted, which makes it difficult to adjust their suction position according to the actual working conditions, thus affecting the dust removal effect of the dust removal device. Therefore, we propose a dust removal device for cement production and its control method. Summary of the Invention

[0024] A fixed plate is fixedly connected to the side of the lifting rod, and the outer surface of the fixed plate has multiple slots.

[0025] A plug assembly is disposed at one end of the connecting block.

[0026] Preferably, the insertion rod assembly includes:

[0027] A square sleeve is fixedly connected to the end face of the connecting block. A partition is fixedly connected inside the square sleeve. A first square cavity is provided on one side of the partition, and a second square cavity is provided on the other side of the partition.

[0028] A movable rod is inserted into the middle of the partition plate. A convex ring is fixedly connected to the middle of the movable rod. A square block is fixedly connected to one end of the movable rod. A push spring is sleeved on the outer surface of the movable rod.

[0032] Preferably, the outer contour of the insert is fan-shaped, and the width of the arc-shaped side of the insert is greater than the width of the widest part inside the slot.

[0033] Secondly, the present invention provides a control method for a dust removal device used in cement production, which is implemented as described above for a dust removal device used in cement production. The specific steps of the control method are as follows:

[0034] Step 1: Move the moving plate along the outer tube to change the telescopic length of the telescopic component, thereby moving the dust hood horizontally. Then rotate the outer block to make the fixed threaded rod press against the moving plate, thereby fixing the position of the dust hood.

[0035] Step 2: Press the round block to separate the locking block from the locking groove, then rotate the sleeve to make the handle drive the connecting shaft to rotate, which in turn drives the gear to rotate, causing the lifting rod to rise and fall, thereby changing the height of the dust cover. Then release the round block to make the return spring drive the locking block to return to its original position and engage with the locking groove.

[0036] Step 3: Move the square block outwards so that the movable rod separates the insert block from the slot. At this point, the flipping rod can be flipped, thereby changing the tilt angle of the pin assembly. Then, use the push spring to reset the movable rod so that the insert block can be inserted into the slot.

[0037] The technical effects and advantages of this invention are as follows:

[0038] 1. This invention changes the horizontal position of the dust hood by extending and retracting the telescopic component. Then, the lifting component can raise and lower the dust hood to adjust its height. The lifting component can then be locked to lock the current height of the dust hood. The dust hood can also be flipped using a flipping rod, and the flipping rod can be positioned using a pin component to fix the current flipping angle of the dust hood. This design allows for quick and easy adjustment of the horizontal position, vertical height, and flipping angle of the dust hood, making it more suitable for cement production areas.

[0039] 2. In this invention, by holding the rotating sleeve and pressing the round block with the thumb until the locking block is removed from the locking groove, the rotating sleeve can be rotated, causing the rotating sleeve to drive the handle to rotate, thus smoothly realizing the raising and lowering of the lifting rod and the dust hood. Later, simply release the pressing round block, causing the return spring to drive the connecting rod to return to its original position, thereby driving the locking block to return to its original position, so that the locking block is locked into the corresponding locking groove. In this way, by using the cooperation between the locking block and the locking groove, the connecting rod and its rotating sleeve are locked, thereby locking the handle, and thus locking the height of the dust hood.

[0040] 3. This invention separates the insert rod assembly from the slot by moving it outward, and then rotates the flip rod, which drives the rotating shaft to rotate, thereby flipping the dust cover. At the same time, the rotating shaft also drives the connecting block and its insert rod assembly to rotate. After adjusting the flip angle of the dust cover, the insert rod assembly is reset and inserted into the slot, thereby fixing the flip rod and thus fixing the flip angle of the dust cover.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] This invention provides, for example Figures 1-5 The image shows a dust removal device used in cement production.

[0050] Example 1: Includes a dust removal equipment body 1 and a connecting corrugated pipe 2. The connecting corrugated pipe 2 is fixedly connected to one side of the middle portion of the dust removal equipment body 1. A dust suction hood 3 is fixedly connected to one end of the connecting corrugated pipe 2, and the dust suction hood 3 is used to suck up dust. A telescopic component 4 is fixedly connected above the connecting corrugated pipe 2. A lifting component 6 is located at the end of the telescopic component 4, and the lifting component 6 can drive the dust suction hood 3 to move up and down. A locking component 7 is provided on the side of the lifting component 6, and the locking component 7 is used to lock the lifting component 6. A flipping rod 8 is rotatably connected to the end of the lifting component 6. A pin component 9 is provided on the side of the flipping rod 8, and the pin component 9 is used to fix the position of the flipping rod 8. The end of the flipping rod 8 is fixedly connected to the outer surface of the dust suction hood 3. By extending and retracting the telescopic component 4, the horizontal position of the dust suction hood 3 is changed, and subsequently, the dust suction hood 3 can be lifted up and down. The lifting component 6 is used to raise and lower the dust collection hood 3, thereby adjusting the height of the dust collection hood 3. Then, the locking component 7 is used to lock the lifting component 6, thereby locking the current height of the dust collection hood 3. The flipping rod 8 can also be used to flip the dust collection hood 3, and then the pin component 9 is used to position the flipping rod 8, thereby fixing the current flipping angle of the dust collection hood 3. This design facilitates quick and easy adjustment of the horizontal position, vertical height, and flipping angle of the dust collection hood 3, making the dust collection hood 3 fit more closely to the cement production area, thus facilitating the dust extraction of the dust collection equipment body 1. The dust enters the connecting corrugated pipe 2 from the dust collection hood 3 and finally enters the dust collection equipment body 1. The dust collection equipment body 1 mainly removes dust from the air by sucking in air. The specific working method can be obtained from existing technology and will not be described in detail here.

[0051] Furthermore, the lifting assembly 6 includes a fixed sleeve 601, which is disposed at one end of the telescopic assembly 4. A lifting rod 602 is slidably disposed inside the fixed sleeve 601. A connecting shaft 603 is rotatably connected to the middle of the fixed sleeve 601. A gear 604 is fixedly connected to the end of the connecting shaft 603. A lifting gear 605 is fixedly connected to one side of the lifting rod 602, and the lifting gear 605 meshes with the gear 604. A throttle 606 is fixedly connected to the end face of one end of the connecting shaft 603. When it is necessary to adjust the height of the dust cover 3, the locking assembly 7 is pre-released from locking the lifting assembly 6, and then... Rotating the throttle 606 causes the connecting shaft 603 to rotate, which in turn drives the gear 604 to rotate. The gear 604, in conjunction with the lifting gear 605, causes the lifting rod 602 to move up and down along the fixed sleeve 601. The lifting rod 602 then drives the flipping rod 8 to move up and down, thereby adjusting the height of the dust hood 3. The lifting assembly 6 is then locked using the locking component 7 to fix the height of the dust hood 3. Specifically, when the throttle 606 rotates forward, the lifting rod 602 moves upward; when the throttle 606 flips, the lifting rod 602 moves downward.

[0052] Furthermore, the locking assembly 7 includes a connecting plate 701, which is fixedly connected to one side of the fixed sleeve 601. An annular cavity 702 is formed inside the connecting plate 701, and an annular groove 703 is formed on one side of the annular cavity 702. Multiple locking grooves 704 are formed on the side of the annular groove 703 near the annular cavity 702. A rotating sleeve 705 is rotatably connected to the end of the handle 606. A connecting rod 706 is inserted into the rotating sleeve 705. A pressing block 707 is fixedly connected to one end of the connecting rod 706, and a return spring 709 is sleeved on the outer surface of the connecting rod 706. A locking block 708 is fixedly connected to the other end of the connecting rod 706. When it is necessary to release the locking assembly 7 from the lifting assembly 6, the rotating sleeve 705 is held by hand, and the pressing block 707 is pressed with the thumb, causing the pressing block 707 to move the connecting rod 704. 6. Move the lever while compressing the return spring 709 until the locking block 708 is removed from the locking groove 704. At this point, the locking component 7 releases the lock on the lifting component 6, allowing the rotating sleeve 705 to rotate, causing the handle 606 to rotate. Simultaneously, the locking block 708 moves along the annular cavity 702, and the connecting rod 706 moves along the annular groove 703, thus smoothly enabling the lifting rod 602 to lift the dust cover 3. Later, simply release the pressing block 707 to reset the return spring 709 and the connecting rod 706, thereby resetting the locking block 708 and causing it to engage with the corresponding locking groove 704. By utilizing the cooperation between the locking block 708 and the locking groove 704, the connecting rod 706 and its rotating sleeve 705 are locked, which in turn locks the handle 606 and thus locks the height of the dust cover 3.

[0053] Furthermore, the outer contour dimensions of the locking block 708 are adapted to the inner contour dimensions of the locking groove 704, and the outer contour of the locking block 708 is set to a conical shape; this facilitates the quick insertion of the locking block 708 into the locking groove 704, thereby making it convenient to lock the lifting assembly 6.

[0054] Furthermore, the pin assembly 9 includes a rotating shaft 901, which is fixedly connected to the end of the flipping rod 8 and rotatably connected to the end of the lifting rod 602. A connecting block 902 is fixedly connected to one end of the rotating shaft 901, and a fixing plate 903 is fixedly connected to the side of the lifting rod 602. The outer surface of the fixing plate 903 has multiple slots 904. The insert rod assembly 905 is disposed at one end of the connecting block 902. First, by moving the insert rod assembly 905 outward, the insert rod assembly 905 is separated from the slot 904. Then, the flipping rod 8 is rotated, causing the rotating shaft 901 to rotate, thereby causing the dust cover 3 to flip. While the rotating shaft 901 rotates, it also causes the connecting block 902 and its insert rod assembly 905 to rotate. After adjusting the flipping angle of the dust cover 3, the insert rod assembly 905 is reset and inserted into the slot 904, thereby fixing the flipping rod 8 and thus fixing the flipping angle of the dust cover 3.

[0055] Furthermore, the insertion rod assembly 905 includes a square sleeve 9051, which is fixedly connected to the end face of the connecting block 902. A partition 9052 is fixedly connected inside the square sleeve 9051. A first square cavity 9053 is provided on one side of the partition 9052, and a second square cavity 9054 is provided on the other side. A movable rod 9055 is inserted into the middle of the partition 9052. A protruding ring is fixedly connected to the middle of the movable rod 9055, and a square block 9056 is fixedly connected to one end of the movable rod 9055. A spring 9057 is fitted onto the outer surface of the 55, and a block 9058 is fixedly connected to the other end of the movable rod 9055. By pulling the square block 9056 outward, the square block 9056 moves the movable rod 9055 outward, simultaneously causing the convex ring to press against the spring 9057 until the block 9058 separates from the slot 904. However, at this point, the square block 9056 is still located inside the second square cavity 9054. Then, by continuing to pull the square block 9056 outward, it separates from the second square cavity 9054. Rotate the square block 9056 180 degrees so that the wider side of the insert block 9058 aligns with the slot 904. Then release the square block 9056, which inserts into the second square cavity 9054, preventing the movable rod 9055 from rotating. Due to the design of the insert block 9058, it will not insert into the slot 904. At this point, the insert rod assembly 905 will not limit the rotation shaft 901, thus smoothly achieving the purpose of rotating the flip rod 8, thereby adjusting the flip angle of the vacuum cleaner hood 3. After adjusting the flip angle of the vacuum cleaner hood 3, move... Pull the square block 9056 outward to separate it from the second square cavity 9054. Then rotate the square block 9056 180 degrees again and release it. At this time, the push spring 9057 drives the movable rod 9055 to reset, so that the insert block 9058 is inserted into the slot 904. The insertion of the insert block 9058 into the corresponding slot 904 limits the connection between the insert block 9058 and the corresponding slot 904, so that the connecting block 902 and the rotating shaft 901 will not rotate, thereby limiting the flipping rod 8 and fixing the flipping angle of the dust cover 3.

[0056] Furthermore, the outer contour of the insert 9058 is fan-shaped, and the width of the arc side of the insert 9058 is greater than the width of the widest part inside the slot 904; this facilitates the mutual restraint between the side of the insert 9058 and the outside of the slot 904, so that the insert 9058 will not be inserted into the slot 904, avoiding the trouble of having to keep pulling the square block 9056 when rotating the flip lever 8.

[0057] Example 2: Based on Example 1, Example 2 further discloses that the telescopic component 4 includes an outer sleeve fixedly connected to the outer surface of the dust removal equipment body 1, a movable plate slidably connected to the inside of the outer sleeve, a fixed threaded rod threadedly connected to the side of the outer sleeve, and an outer circular block fixedly connected to one end of the fixed threaded rod. By moving the movable plate along the inside of the outer sleeve, the lifting component 6 and its dust suction hood 3 are moved. Then, the outer circular block is rotated, causing the outer circular block to drive the fixed threaded rod to rotate, causing the fixed threaded rod to press the movable plate, thereby fixing the movable plate and locking the horizontal position of the dust suction hood 3.

[0058] Furthermore, a horizontal plate 5 is fixedly connected to one end of the movable plate, and the end of the horizontal plate 5 is fixedly connected to the top of the corresponding fixed sleeve 601; this facilitates the connection of the movable plate to the two fixed sleeves 601 using the horizontal plate 5.

[0059] A control method for a dust removal device used in cement production, wherein the specific steps of the control method for implementing the aforementioned dust removal device for cement production are as follows:

[0060] Step 1: Move the moving plate along the outer tube to change the telescopic length of the telescopic component 4, thereby driving the dust cover 3 to move horizontally. Then rotate the outer block to make the fixed threaded rod press the moving plate, thereby fixing the position of the dust cover 3.

[0061] Step 2: Press the pressing round block 707 to separate the locking block 708 from the locking groove 704. Then rotate the rotating sleeve 705 to make the handle 606 drive the connecting shaft 603 to rotate, thereby driving the gear 604 to rotate, so that the lifting rod 602 can be raised and lowered, thereby changing the height of the dust cover 3. Then release the pressing round block 707 to make the return spring 709 drive the locking block 708 to return to its original position and insert into the locking groove 704.

[0062] Step 3: Move the square block 9056 outward so that the movable rod 9055 drives the insert block 9058 to separate from the slot 904. At this time, the flip rod 8 can be flipped, thereby changing the tilt angle of the pin assembly 9. Then, the push spring 9057 drives the movable rod 9055 to reset, so that the insert block 9058 can be inserted into the slot 904.

Then release the pressing round block (707) so that the reset spring (709) drives the locking block (708) to reset and insert into the locking groove (704); Step 3: Move the square block (9056) outward so that the movable rod (9055) drives the insert block (9058) to separate from the slot (904). At this time, the flip rod (8) can be flipped, thereby changing the tilt angle of the pin assembly (9). Then, the push spring (9057) drives the movable rod (9055) to reset, so that the insert block (9058) can be inserted into the slot (904).
