Dust collection system

Abstract

This invention provides a dust collection system, including a fixed frame, a storage box for collecting dust and forming a powdery sludge, a slag-removing device for scooping the powdery sludge from the storage box and transferring it to a slag cake making device, and a slag cake making device for squeezing the powdery sludge to remove water and forming a slag cake. Both the slag-removing device and the slag cake making device are mounted on the fixed frame. The slag-removing device is located above one side of the storage box, and a dust collector is located above the other side of the storage box. The slag cake making device is located below and behind the slag-removing device. Dust falls from the dust collector into the storage box, becoming powdery sludge. The slag-removing device then drains and carries the powdery sludge out of the storage box, turning it into slag, which is then sent to the slag cake making device. Under squeezing, the slag is dehydrated again, forming a slag, which falls into a collection box below for collection and reuse. The dust collection system proposed in this invention has good applicability, high safety, energy saving, and high recycling rate. It requires no cleaning and is easy to transport.

Description

Technical Field

[0001] This invention belongs to the field of dust removal technology, specifically relating to a dust collection system. Background Technology

[0002] Existing dust collection devices are divided into dry and wet dust collection. After dust collection, both dry and wet dust are placed in the water tank of the dust collection device. Regarding the collection of dust from the water tank, the current method mainly involves using scrapers on a chain to lift the dust that has fallen into the water tank into a collection box, which is then transported away. The disadvantages of this method are: 1. Because it operates underwater, and the dust is dirty, irregular in size, and prone to clumping, it affects the normal operation of the chain conveyor system; 2. During transmission, the chain experiences friction from the sprockets, guides, and the outer casing. When transporting flammable dust, this friction poses a safety hazard, increasing the risk of transmission; 3. Chain conveying is a fixed transmission method and cannot produce displacement in other directions, so it can only scrape dust already in a fixed position, resulting in poor cleaning efficiency. Therefore, it is necessary to develop a dust collection system to solve the above problems. Summary of the Invention

The slag removal device includes a working box, a brush head, a brush rod, and a first motor. The slag cake making device includes a working cylinder, a first cake pusher, a cake pusher rod, a second cake pusher, a second motor, and a second cylinder. A movable support plate is provided on the top of the working box. The first motor is fixed on the movable support plate. The brush rod passes through the movable support plate and extends into the working box from the top. The bottom end of the brush rod is connected to the brush head. The first motor controls the raising and lowering of the brush rod. When the brush rod lowers, the brush head extends into the storage box. When the brush rod rises, the brush head... The material is raised into the working box. A clay outlet is provided on the rear side wall of the working box. The working cylinder is located below the clay outlet. A material discharge port is provided above the annular wall of the working cylinder. The clay outlet is aligned with the material discharge port. The second motor is fixed on the fixed frame.

The movable support plate is movably connected to the working box through a second rotating shaft. The extension shaft of the first cylinder is fixedly connected to the movable support plate. When the first cylinder is started, the extension shaft of the first cylinder drives the movable support plate to move.

[0008] As a preferred embodiment of the dust collection system of the present invention, the slag removal device further includes a sensing fixing rod, which is installed on the movable support plate and is parallel to the brush rod. A first sensor and a second sensor are installed on the sensing fixing rod, with the first sensor close to the movable support plate and the second sensor away from the movable support plate.

[0009] As a preferred embodiment of the dust collection system of the present invention, the slag removal device further includes a funnel, which is disposed on the rear side wall of the working box. The top and side wall of the funnel are enclosed as an integral structure. The funnel covers the sludge outlet, and the bottom of the funnel is open, with the open end aligned with the discharge port.

[0010] As a preferred embodiment of the dust collection system of the present invention, the slag cake making device further includes a third cylinder, a cover, and a movable frame. The third cylinder is fixed on the fixed frame, and the extension shaft of the third cylinder is fixedly connected to the first rotating shaft. The movable frame is movably connected to the fixed frame through the first rotating shaft. The second cylinder is fixed on the movable frame. When the third cylinder is started, the first rotating shaft drives the movable frame to rotate, causing the second cylinder to rotate. The second cylinder is connected to the cover, and the cover is sleeved on the extension shaft of the second cylinder and the second slag cake. The inner diameter of the cover is the same as the inner diameter of the working cylinder.

Detailed Implementation

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to specific embodiments.

[0031] First, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, this invention is described in detail using structural diagrams, etc. When detailing the embodiments of this invention, for ease of explanation, the schematic diagrams illustrating the structure of the dust collection system may be partially enlarged, not according to general proportions. Furthermore, these schematic diagrams are merely examples and should not limit the scope of protection of this invention. In addition, actual manufacturing should include three-dimensional space with length, width, and depth.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the dust collection system of the present invention. Figure 1 As shown, for ease of understanding, the dust collection system is divided into the following parts: a fixed frame 1 for forming its basic framework structure; a storage box 2 for collecting dry or wet dust from the dust collector (not shown) and forming a sludge deposit; a sludge removal device 3 for scooping up the sludge from the storage box 2 and transferring it to the sludge cake making device 4; and a sludge cake making device 4 for squeezing the sludge to remove water and making a sludge cake.

[0034] The basic connection of the above structure is that both the slag-removing device 3 and the slag cake-making device 4 are mounted on the fixed frame 1. The slag-removing device 3 is located above one side of the accumulation box 2, and the dust collector is located above the other side of the accumulation box 2. The slag cake-making device 4 is located below and behind the slag-removing device 3. Dry or wet dust falls from the dust collector into the water-filled accumulation box 2, turning into sludge. The slag-removing device 3 then drains the sludge from the accumulation box 2, turning it into slag, which is then sent to the slag cake-making device 4. Under the pressure of compression, the slag is dehydrated again and turns into slag cake, which falls into the collection box (not shown) below for collection and reuse. To better understand the structure of each device, each device is described below:

[0035] 1. Storage Box 2

[0036] Please continue reading. Figure 1 and combined Figure 2 , Figure 2 This is a schematic diagram of the accumulation box in the dust collection system of the present invention. Figure 1 and 2As shown, the storage box 2 is divided into a sloped area 20 and an arc-shaped area 21. The sloped area 20 and the arc-shaped area 21 are interconnected without any gaps. The purpose of distinguishing them is that the sloped area 20 and the arc-shaped area 21 have different structures and uses. Above the sloped area 20 is the dust collection hopper of the dust collector (not shown). Waste dust collected by the dust collector falls from the dust collection hopper into the sloped area 20, and due to the slope, it quickly slides down to the bottom of the storage box 2. Because of the different characteristics of dry and wet dust, the slope needs to be adjusted accordingly. The requirements are different: When the dust collector is a dry dust collector, the slope of slope zone 20 is 65-75 degrees. This is because dry dust contains no water and requires a slope angle to guide it and provide the force for its descent. When the dust collector is a wet dust collector, the slope of slope zone 20 is 25-45 degrees. This is because water has an impact force, and the wet dust (containing water) coming out of the dust collector flows from top to bottom. Through the guidance of the slope and the force of the incline, the water containing water can be guided to the effective working range of the brush head 6 of the slag removal device 3. If the slope setting in either of these two cases is too low, it will be impossible to guide the dry and wet dust into the sweeping working range of the brush head 6. If the slope is too high, it will affect the applicability of the site setup. It should also be noted that the accumulation tank 2 is already filled with water before use. Please continue reading. Figure 1 and Figure 2 Above the curved area 21 is the working box 5 of the slag removal device 3. Its purpose is to facilitate the collection of dry and wet dust by the brush head 6 and send it into the working box 5 more easily. Moreover, the rounded design of the curved area 21 ensures that the accumulation box 2 has no dead corners, making it easy for the brush head 6 to clean.

[0037] 2. Slag extraction device 3

[0038] Please continue reading. Figure 1 and combined Figures 3 to 5 , Figure 3 This is a schematic diagram of the slag removal device of the dust collection system of the present invention from one angle; Figure 4 This is a schematic diagram of the slag removal device of the dust collection system of the present invention from another angle; Figure 5 This is a schematic diagram of a portion of the structure of the slag removal device in the dust collection system of the present invention. Figure 1 and Figures 3 to 5 As shown, the slag removal device 3 mainly includes components such as a connecting plate 22, a working box 5, a brush head 6, a brush rod 7, a first motor 8, and a first cylinder 23. The connecting plate 22 extends into the storage box 2 and fits against the arc area 21. Its function is to make the storage box 2 and the slag removal device 3 seamlessly connected. The top of the connecting plate 22 is connected to the rear side wall 16 of the working box 5. This arrangement allows the brush head 6 to carry the sludge out of the storage box 2 and directly send it to the sludge outlet 17 on the rear side wall 16.

[0039] Please continue reading. Figures 3 to 5 ,like Figures 3 to 5As shown, the work box 5 is fixed on the fixed frame 1. A movable support plate 15 is provided on the top of the work box 5. The movable support plate 15 is movably connected to the work box 5 through the second rotating shaft 24. The first motor 8 is fixed on the movable support plate 15. The brush rod 7 passes through the movable support plate 15 and extends into the work box 5 from the top. The bottom end of the brush rod 7 is connected to the brush head 6. The first motor 8 controls the raising and lowering of the brush rod 7. The brush rod 7 is a screw, which is movably connected to the output end of the first motor 8 through the first transmission actuator (not shown). When the first motor 8 is started, the first transmission actuator rotates, while the brush rod 7 does not rotate, and the brush rod 7 is guided to rise and fall. Therefore, when it is necessary to clean the powder mud in the accumulation box 2, the first motor 8 is started, the brush rod 7 descends, and the brush head 6 extends into the accumulation box 2; when the brush rod 7 rises, the brush head 6 carries the powder mud into the work box 5 and sends the powder mud out from the powder mud outlet 17.

[0040] Please continue reading. Figures 3 to 5 ,like Figures 3 to 5 As shown, the first cylinder 23 is mounted on the front side wall (not shown) of the work box 5. The extension shaft of the first cylinder 23 is fixedly connected to the movable support plate 15. When the first cylinder 23 is started, the extension shaft of the first cylinder 23 drives the movable support plate 15 to move around the second rotating shaft 24. In order to enhance the load-bearing capacity of the cylinder seat, a channel steel 31 is installed on the front side wall of the work box 5, and the channel steel 31 fixes the bottom of the first cylinder 23.

[0041] In the above process, the movable support plate 15 is used to fix the first motor 8. Moreover, the movable support plate 15 can also move around the second rotating shaft 24 according to the thrust of the first cylinder 23. The purpose is to ensure that the brush head 6 can always stick to the bottom of the storage tank 2 when it is submerged underwater, so as to scrape the mud.

[0042] To ensure that the brush head 6 can remove all the clay powder from the collection box 2 and drain the water, the bristles of the brush head 6 cannot be too dense or too sparse. The bristles are made of acid and alkali resistant materials, such as DuPont PA66. The length of the bristles is also required; if they are too long, they are easy to deform, and if they are too short, they are not conducive to collecting the clay powder.

[0043]

[0044]

[0045] Table 1

[0046] As shown in Table 1, the brush head 6 has 3 to 6 rows of mounting holes. Any two adjacent rows of mounting holes (not shown) are staggered. Each mounting hole contains a cluster of bristles composed of multiple bristles. Each bristle is 40 to 60 mm long and 0.05 to 0.1 cm in diameter. This structure is most conducive to the extraction of powder residue.

[0047] When the brush head 6 is inserted into the storage tank 2, the extension shaft of the first cylinder 23 is at its longest, and the brush rod 7 is at its longest in the water. When the brush head 6 is lifted, the extension shaft of the first cylinder 23 moves first, pressing the brush rod 7 down so that the brush head 6 is against the bottom wall of the storage tank 2. Then the brush rod 7 is lifted by the action of the first motor 8.

[0048] To control the distance the brush rod 7 rises or falls, the slag removal device 3 also includes a sensing fixing rod 25. The sensing fixing rod 25 is parallel to the brush rod 7 and is also installed on the movable support plate 15. A first sensor 26 and a second sensor 27 are installed on the sensing fixing rod 25. The first sensor 26 is used to locate the depth of the brush head 6, and the second sensor 27 is used to limit the position of the brush head 6. Therefore, the first sensor 26 is located close to the movable support plate 15, while the second sensor 27 is farther away from the movable support plate 15.

[0049] Please continue reading. Figures 3 to 5 and combined Figure 6 and Figure 9 , Figure 6 This is a schematic diagram of the slag removal device and slag cake making device of the dust collection system of the present invention. Figure 9 This is a schematic diagram of the slag removal device and slag cake making device of the dust collection system of the present invention from another angle. Figures 3 to 6 As shown in Figure 9, after the clay powder is drained by the lifting of the brush head 6, it becomes loose powder residue. Since the clay powder outlet 17 is located on the rear side wall 16, the powder residue coming out of the clay powder outlet 17 may not fall well into the discharge port 18 below. To solve this problem, a funnel 28 can be installed on the rear side wall 16 of the working box 5. The funnel 28 covers the clay powder outlet 17, and the bottom of the funnel 28 is open (not shown). The open end is aligned with the discharge port 18. In this way, through the guiding effect of the funnel 28, the powder residue falls from the clay powder outlet 17 into the funnel 28, and is gathered by the funnel 28, so that the powder residue falls from the open end into the discharge port 18 of the working cylinder 9 below. It should be noted that... Figures 3 to 6 The funnel in the middle is in an unclosed state, but in the final forming equipment, the top and side walls of the funnel 28 are closed into a single structure.

[0050] III. Slag Cake Making Device 4

[0051] Please continue reading. Figure 6 and combined Figures 7 to 8 , Figure 7 This is a schematic diagram of the slag cake making device of the dust collection system of the present invention from one angle. Figure 8 This is a schematic diagram of the slag cake making device of the dust collection system of the present invention from another angle. Figures 6 to 8As shown, the slag cake making device 4 includes a working cylinder 9, a first cake pusher 10, a cake pusher rod 11, a second cake pusher 12, a second motor 13, and a second cylinder 14. The working cylinder 9 is located below the sludge outlet 17. A discharge port 18 is provided above the annular wall of the working cylinder 9, and the opening of the funnel 28 is aligned with the discharge port 18. The second motor 13 is fixed on the fixed frame 1. The output shaft of the second motor 13 is connected to the cake pusher rod 11. The cake pusher rod 11 is a screw, and one end of it is movably connected to the output shaft of the second motor 13 through a second transmission actuator (not shown). When the second motor 13 is started, the second transmission actuator rotates, while the cake pusher rod 11 does not rotate. The cake pusher rod 11 only performs lateral extension and retraction movements. The other end of the pusher rod 11 is fixedly connected to the first pusher 10. The first pusher 10 is inserted into the working cylinder 9 from one end, and its diameter matches the inner diameter of the working cylinder 9. The second cylinder 14 is movably connected to the fixed frame 1 via the first rotating shaft 19. The extension shaft of the second cylinder 14 is fixedly connected to the second pusher 12. The second pusher 12 is inserted into the working cylinder 9 from the other end, and its diameter matches the inner diameter of the working cylinder 9. When the second motor 13 and the second cylinder 14 are started, the second motor 13 pushes the first pusher 10, and the second cylinder 14 pushes the second pusher 12. At this time, the first pusher 10 and the second pusher 12 compress the powder residue in the working cylinder 9 into a cake shape. In a preferred embodiment, a coagulant can be sprayed onto the powder residue to enhance cake formation. This method can effectively prevent the powder residue from turning back into dust due to excessively long bagging, transportation, and drying times. After the first pusher 10 and the second pusher 12 compress the powder residue in the working cylinder 9 into powder cakes, it is also necessary to consider removing and collecting the powder cakes from the working cylinder 9. Therefore, in order to achieve automatic material discharge (powder cakes), the powder cake making device 4 is also equipped with a third cylinder 29, a cover 30 and a movable frame (not shown). The third cylinder 29 is fixed on the fixed frame 1, and the extension shaft of the third cylinder 29 is fixedly connected to the first rotating shaft 19. The movable frame is movably connected to the fixed frame 1 through the first rotating shaft 19. The second cylinder 14 is fixed on the movable frame. When the third cylinder 29 is started, the first rotating shaft 19 drives the movable frame to rotate, causing the second cylinder 14 to rotate. The extension shaft end of the second cylinder 14 is covered with a cylindrical cover 30. The inner diameter of the cover 30 is the same as the inner diameter of the working cylinder 9. When the second pusher 12 is parallel to the first pusher 10, the cover 30 and the working cylinder 9 form a complete cylindrical structure. The extension shaft of the third cylinder 29 drives the first rotating shaft 19 to rotate by an angle of 270 degrees.

[0052] The working principle of the above structure is as follows:

[0053] 1. The powder residue falls into the working cylinder 9, and the second motor 13 pushes the pusher rod 11 forward. At this time, the pusher rod 11 (screw) does not rotate but makes an extension movement. The second transmission rotates flexibly. Through the extension of the pusher rod 11, the first pusher 10 squeezes the powder residue towards the second pusher 12.

[0054] 2. The second cylinder 14 is started and moves in a telescopic motion from the direction of the second pusher 12 to the direction of the first pusher 10, so that the second pusher 12 squeezes the powder and residue multiple times.

[0055] 3. When the third cylinder 29 is activated, its output shaft rotates 270 degrees, causing the second cylinder 14 to flip under the drive of the first rotating shaft 19. At this time, the second cylinder 14, the cover 30, and the second pusher 12 leave the working cylinder 9, so that one end of the working cylinder 9 near the second cylinder 14 is in an open state, and the powder falls from this opening into the collection box below (not shown).

[0056] The effects of extruding the powder mentioned above are detailed in Table 2.

[0057]

[0058]

[0059] Table 2

[0060] As shown in Table 2, the best powder cake making effect is achieved when the second pusher 12 moves from the direction of the second pusher 12 to the direction of the first pusher 10, so that the second pusher 12 squeezes the powder residue 5 to 10 times, and each time stays for 30 to 50 minutes.

[0061] The structure of the collection box is not an inventive point of this invention. There are many ways to set it up. It is recommended to have an upper filter screen and a lower closed box structure. This structure is conducive to collecting the squeezed water into the lower closed box structure, which is easy to pour out, while the upper filter screen is conducive to collecting the powder cake and drying it again.

[0062] In the above three parts, the first motor 8, the second motor 13, the first cylinder 23, the second cylinder 14, the third cylinder 29, the first sensor 26, and the second sensor 27 are all electrically connected to the power supply, and according to their working principle requirements, corresponding PLC control circuit boards or operation display screens can also be set.

[0063] The working principle of the dust collection system of the present invention is described in detail below:

[0064] The waste dust (dry or wet dust) collected by the dust collector falls from the dust collection hopper to the slope area 20 of the accumulation box 2, and eventually falls to the bottom of the accumulation box 2, which is filled with water. At this time, the waste dust has settled at the bottom of the accumulation box 2, forming a sludge-like substance. When the collected sludge reaches a certain amount and needs to be cleaned from the accumulation box 2, the first motor 8 is started, causing the brush rod 7 to descend and the brush head 6 to extend into the accumulation box 2. The first sensor 26 locates the depth of the brush head 6, and at the same time, the first cylinder 23 is started, extending its shaft to its maximum length, allowing the brush... As the position of the movable support plate 15 changes, the brush head 6 is at the bottom of the storage box 2. When the brush head 6 moves back, the extension shaft of the first cylinder 23 actuates, causing the position of the movable support plate 15 to change, creating a downward force on the brush rod 7, causing the brush head 6 to adhere to the bottom wall of the storage box 2. Under this operation, the brush head 6 carries the powder and mud collected during the retraction process. Then, the brush rod 7 is lifted by the action of the first motor 8, ensuring that the brush head 6 remains in close contact with the bottom of the storage box 2 or the connecting plate 2. The bottom surface of the brush head 6 ensures that the powder is scraped. After the brush head 6 carries the powder out of the storage tank 2, the excess water falls back into the storage tank 2. The remaining powder residue is sent directly along the connecting plate 22 to the powder residue outlet 17 on the rear side wall 16 by the brush head 6. The second sensor 27 is used to limit the lifting position of the brush head 6. When it reaches the lifting detection point, the first motor 8 stops working. Guided by the funnel 28, the powder residue falls from the powder residue outlet 17 into the funnel 28 and is gathered by the funnel 28, so that the powder residue falls from the open into the lower working cylinder 9. At the feed inlet 18, once a certain amount has accumulated, the second motor 13 starts, pushing the pusher rod 11 forward. The extension of the pusher rod 11 causes the first pusher 10 to push the powder residue towards the second pusher 12. The second cylinder 14 is then activated, extending and retracting from the second pusher 12 towards the first pusher 10, causing the second pusher 12 and the first pusher 10 to press the powder residue against each other 5-10 times, each time for 30-50 minutes, forming a powder cake. During the pressing process, excess water falls into the box-shaped structure at the bottom of the collection box. After the powder cake is made, the third cylinder 29 is activated, its output shaft rotating 270 degrees, causing the second cylinder 14 to flip under the drive of the first rotating shaft 19. At this time, the second cylinder 14, the cover 30, and the second pusher 12 move away from the working cylinder 9, leaving one end of the working cylinder 9 near the second cylinder 14 open, allowing space for the powder cake to fall. The powder cake falls from this opening onto the filter screen of the collection box below.

[0065] The above process completes the entire operation of the dust collection system.
