Description

Technical Field

[0001] This utility model relates to the field of dry and wet separation technology of coal dust, and more specifically, to a dry and wet separation and collection device for moist coal dust. Background Technology

[0002] The modern coal industry pursues intelligent, automated, and clean production. A factory with coal sludge everywhere and wastewater flowing freely is unacceptable and hinders equipment operation. An efficient collection and separation system is a crucial element in achieving clean workshops and continuous automated production.

[0003] Existing publication number CN120172622A discloses a mobile vertical dry-wet separation device for mining, including a dry-wet separation main unit and a moving mechanism. The dry-wet separation main unit includes a feeding pipe and a separation component. The top of the feeding pipe is connected to the bottom of the separation component. A feed inlet is opened at the bottom of the side wall of the feeding pipe. A rotatable mandrel is installed inside the feeding pipe. Spiral blades are fixed on the mandrel. A first driving device is provided at the top of the separation component. The moving mechanism is used to move the dry-wet separation main unit in a sedimentation tank. Through the mandrel and spiral blades, the material can be lifted into the separation component, where the separation component performs dry-wet separation on the material. It integrates material collection, lifting, and squeezing, and is safe and efficient for underground or above-ground operations in coal mines. The inventors discovered the following problems with the existing technology during the development of this utility model: Existing wet coal dust treatment devices mostly adopt a single separation structure, which can only achieve basic dry and wet screening. They lack a synergistic process of layered centrifugal separation and deep pressure filtration, as well as a supporting wastewater purification module. The coal dust separation is incomplete and the wastewater is directly discharged, which not only wastes water resources but also easily causes secondary dust pollution. Therefore, a wet and dry separation and collection device for wet coal dust is proposed to address the above problems. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wet and dry separation and collection device for wet coal dust to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wet and dry coal dust separation and collection device, comprising a separation cabinet, a separation mechanism, a material guiding mechanism, and a filter press assembly. The separation cabinet has a door hinged to one side; a handle is fixed to the surface of the door; a separation mechanism is provided in the middle of the separation cabinet; a material guiding mechanism is provided at the bottom of one end of the separation mechanism; and a filter press assembly and a water treatment unit are installed at the bottom of the material guiding mechanism.

[0006] By adopting the above technical solution, a modular structure integrating the separation mechanism, material guiding mechanism, filter press assembly and water treatment unit is used. The cabinet door is hinged to the side of the separation cabinet and equipped with a handle. The components are arranged in layers to form an integrated process from separation, material guiding, filter press to water treatment, realizing the whole process treatment of wet coal dust. The modules are closely connected, which not only ensures the integrity of dry and wet separation, but also completes wastewater purification at the same time, greatly improving the comprehensive treatment capacity and environmental benefits of the device.

[0007] Preferably, a limiting plate is fixedly attached to the surface of the cabinet door; the limiting plate adheres to the side wall of the separation cabinet to form a limiting position when the cabinet door is closed.

[0008] By adopting the above technical solution, a limiting plate is added to the cabinet door. The limiting plate can fit against the side wall of the separation cabinet when the cabinet door is closed. This protruding limiting structure does not require additional locking components. It relies on physical fit to form a limit and uses the friction of the contact surface to limit the vibration and displacement of the cabinet door. This not only enhances the internal airtightness of the separation cabinet and prevents coal dust from overflowing, but also simplifies the cabinet door fixing structure.

[0009] Preferably, a plurality of first magnetic blocks are fixedly attached to the surface of the limiting plate; a plurality of second magnetic blocks are fixedly attached to a preset groove on one side of the separation cabinet, and the positions of the second magnetic blocks correspond to those of the first magnetic blocks.

[0010] By adopting the above technical solution, a first magnetic block is set on one side of the limiting plate and a second magnetic block is set in the preset slot of the separation cabinet, and the two are positioned correspondingly to form a double fixing structure of magnetic attraction plus physical limitation. The magnetic attraction, together with the fitting limitation of the limiting plate, makes the cabinet door close more firmly and eliminates the problem of dust leakage from the gaps in the cabinet door during equipment operation. At the same time, the magnetic attraction is convenient to open and close, without the need for manual locking.

[0011] Preferably, the separation mechanism includes a rotating shaft installed in the middle of the separation cabinet; a plurality of supports are fixedly connected to the middle of the rotating shaft; a separation bucket is fixedly connected to the end of the support; and a plurality of filter holes are formed on the surface of the separation bucket.

[0012] By adopting the above technical solution, the separation mechanism is a centrifugal structure with multiple sets of brackets supporting the separation barrel through a rotating shaft. The surface of the separation barrel is evenly distributed with filter holes. This coaxial rotating separation structure has obvious advantages. The brackets can stabilize the separation barrel and prevent shaking during high-speed rotation. The filter holes are uniform in filtering water to ensure the uniformity of centrifugal separation. It can quickly achieve the initial dry and wet separation of coal dust, reduce the processing load of the subsequent pressure filtration stage, and improve the overall separation efficiency.

[0013] Preferably, the material guiding mechanism includes a material guiding pipe fixed to the bottom of the separation cabinet, and the material guiding pipe has a tapered rectangular structure; a connecting pipe is fixed to the bottom of the material guiding pipe; a rotating rod is rotatably connected to the middle of the material guiding pipe; and multiple pusher wheels are fixed to the surface of the rotating rod.

[0014] By adopting the above technical solution, the material guiding mechanism is a tapered rectangular material guiding pipe equipped with a rotating rod and multiple pusher wheels, with a connecting pipe at the bottom. The tapered structure can accelerate the collection of wastewater, and the rotating pusher wheels can push the material. Its advantages are that the special shape of the material guiding pipe avoids wastewater residue, the rotation of the pusher wheels can prevent pipe blockage, and the connecting pipe can achieve seamless docking with subsequent components, making material conveying smoother, eliminating conveying dead angles, and improving the stability of continuous operation of the device.

[0015] Preferably, the filter press assembly includes a circular tube fixed to the end of the connecting pipe; a filter press is fixed to one end of the circular tube; multiple elastic diaphragms are installed in the middle of the filter press; a discharge pipe is installed at one end of the filter press; and a valve is installed in the middle of the discharge pipe.

[0016] By adopting the above technical solution, the filter press assembly is a circular tube connected to the filter press and has multiple sets of elastic diaphragms built in. The end is equipped with a discharge pipe and a valve. The advantage of the elastic diaphragm filter press structure is that the elastic diaphragm can repeatedly expand to deeply filter the wastewater, greatly improve the dryness of the coal slime, and the valve can accurately control the discharge rhythm to avoid the accumulation of dry coal slime.

[0017] Preferably, the water treatment unit includes a thickener installed at the other end of the circular tube; a purifier is installed on one side of the thickener to purify the filtered water into reusable clean water.

[0018] By adopting the above technical solution, the water treatment unit is a staged water treatment structure with a thickener before and a purifier after. The thickener first settles large particulate impurities, and the purifier then performs deep purification. The thickener can reduce the purification load of the purifier and extend its service life. The purifier can purify wastewater into reusable clean water, realize the resource utilization of wastewater, reduce water consumption and reduce sewage discharge costs, and meet the needs of green production.

[0019] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this wet coal dust dry-wet separation and collection device integrates centrifugal separation of the separation mechanism and deep filtration of the filter press assembly. First, the separation barrel is rotated at high speed by the rotating shaft to achieve preliminary dry-wet separation. Then, the coal slime is dewatered by repeated squeezing of the elastic diaphragm in the filter press. This solves the drawback of incomplete treatment by a single separation structure.

[0020] Compared with existing technologies, this wet coal dust dry-wet separation and collection device uses a graded water treatment system with a matching water treatment unit. The thickener first settles fine coal slime, and the purifier then purifies and reuses the wastewater. This not only avoids the waste of resources caused by direct discharge of wastewater, but also prevents secondary dust generation by combining the magnetic sealing structure of the first and second magnetic blocks. This achieves the unity of efficient coal dust separation and wastewater resource utilization. Attached Figure Description

[0027] 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. Example 1

[0028] As attached Figures 1 to 5 The wet coal dust dry-wet separation and collection device shown includes a separation cabinet 1, a separation mechanism 13, a material guiding mechanism 14, and a filter press assembly 15. A cabinet door 11 is hinged to one side of the separation cabinet 1; a handle 12 is fixed to the surface of the cabinet door 11; a separation mechanism 13 is provided in the middle of the separation cabinet 1; a material guiding mechanism 14 is provided at the bottom of one end of the separation mechanism 13; a filter press assembly 15 and a water treatment unit 16 are installed at the bottom of the material guiding mechanism 14.

[0029] In this process, after the damp coal dust is fed into the separation cabinet 1, the separation mechanism 13 separates it, the material guiding mechanism 14 guides the material to the filter press assembly 15 for deep treatment, the water treatment unit 16 simultaneously purifies the wastewater, the cabinet door 11 is opened and closed by hinges, the handle 12 is easy to operate, and the various components work together to form a complete processing flow, preventing coal dust from overflowing. The water treatment unit 16 allows the wastewater to be reused, reducing water consumption and improving the continuity and environmental friendliness of separation and collection. Example 2

[0030] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details: In a preferred embodiment, when the cabinet door 11 is closed, the limiting plate 2 fits tightly against the side wall of the separation cabinet 1, restricting the displacement of the cabinet door 11 from the side and preventing the cabinet door 11 from loosening due to vibration during equipment operation. This limiting method does not require a complex structure, relies on the friction of the fit to stabilize the cabinet door 11, reduces mechanical wear, extends the life of components, and at the same time ensures a sealed environment inside the separation cabinet 1, improving separation efficiency.

[0031] In a preferred embodiment, after the cabinet door 11 is closed, the first magnetic block 3 on the limiting plate 2 precisely engages with the second magnetic block 31 in the preset slot of the separation cabinet 1, doubly reinforcing the cabinet door 11. The magnetic attraction combined with the limiting structure makes the cabinet door 11 close more tightly, preventing coal dust from leaking from the gaps. Moreover, the magnetic attraction makes opening and closing convenient, eliminating the need for additional locks, shortening the equipment start-up and shutdown intervals, and improving operating efficiency.

[0032] In a preferred embodiment, the motor drives the rotating shaft 4 to drive the support 41 and the separation tank 42 to rotate at high speed. Under the action of centrifugal force, the coal dust adheres to the wall, and the water seeps out through the filter holes 43. The support 41 stably supports the separation tank 42 to prevent shaking during rotation. The filter holes 43 are evenly distributed to ensure uniform water filtration, improve the initial separation effect, reduce the load of subsequent processing, and the structural design of the separation tank 42 also facilitates subsequent coal dust cleaning.

[0033] In a preferred embodiment, the wastewater separated by the separation mechanism 13 flows into the feed pipe 5, whose tapering structure accelerates the water flow. The rotating rod 52 drives the pusher wheel 53 to push the wastewater to the connecting pipe 51. The special structure of the feed pipe 5 prevents wastewater residue, the pusher wheel 53 effectively prevents pipe blockage, and the connecting pipe 51 achieves seamless connection with the filter press assembly 15, making material conveying smoother and improving the overall processing rate.

[0034] In a preferred embodiment, wastewater enters the circular pipe 6 through the connecting pipe 51. The filter press 61 drives the elastic diaphragm 62 to repeatedly expand and squeeze, drying the residual coal slime. The dry material is discharged through the discharge pipe 63, and the valve 64 controls the timing of discharge. The elastic properties of the elastic diaphragm 62 ensure thorough filtration and improve the dryness of the coal slime. The valve 64 provides precise control to prevent material accumulation. The structural design of the circular pipe 6 allows for an orderly connection between filtration and discharge.

[0035] In a preferred embodiment, the wastewater discharged from the circular pipe 6 enters the thickener 7, where fine coal slime is separated by sedimentation, and then the water flows into the purifier 71 for deep purification. The thickener 7 first removes large particulate impurities, reducing the burden on the purifier 71. The purifier 71 then uses multiple purification processes to ensure the wastewater meets standards for reuse, achieving dual recycling of solid waste and wastewater, reducing sewage discharge costs, and meeting the requirements of green production.

[0036] In this embodiment, the filter press 61 and the purifier 71 are commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them and have not made any structural or functional improvements. We will not go into detail here.

[0037] The working process of this utility model is as follows: First, the wet coal dust is sent into the separation mechanism 13 inside the separation cabinet 1: the motor drives the rotating shaft 4 to drive the separation barrel 42 to rotate at high speed. Under the action of centrifugal force, the coal dust sticks to the inner wall of the separation barrel 42, and the water in it seeps through the filter hole 43 to the outside of the separation barrel 42, thus initially realizing the separation of dry and wet. The dry coal dust is temporarily stored in the separation barrel 42, and the wastewater containing coal slurry falls into the guiding mechanism 14 below under gravity. At this time, the cabinet door 11 is limited by the limiting plate 2 sticking to the side wall of the separation cabinet 1, and is magnetically closed with the second magnetic block 31 on the separation cabinet 1 by the first magnetic block 3, ensuring the sealing of the inside of the separation cabinet 1.

[0038] Subsequently, the rotating rod 52 in the feeding mechanism 14 drives the pusher wheel 53 to rotate, pushing the wastewater to the connecting pipe 51 and into the circular pipe 6 of the filter press assembly 15. After the filter press 61 is started, the internal elastic diaphragm 62 repeatedly expands and squeezes, deeply filtering the residual coal sludge in the wastewater. The filtered dry coal sludge is discharged through the discharge pipe 63 and controlled by the valve 64. The filtered wastewater is then transported to the thickener 7 in the water treatment unit 16. The thickener 7 first performs sedimentation treatment on the wastewater, allowing the fine coal sludge particles remaining in the wastewater to settle to the bottom under gravity, achieving preliminary solid-liquid separation. After preliminary separation, the water enters the purifier 71, which purifies the water into clean water that meets the reuse standards through filtration and adsorption, ultimately completing the resource treatment of the wastewater. The above is the working principle of the wet coal dust dry-wet separation and collection device.
