Description

Technical Field

[0001] This invention relates to the field of material reduction and sample preparation technology, and in particular to a divider reduction cabinet and its usage method. Background Technology

[0002] In the sample preparation process for testing materials such as coal, minerals, and ores, the divider reduction cabinet, relying on its multi-compartment alternating flow distribution structure, can achieve equal and uniform distribution of materials, effectively reducing reduction errors. It is currently the mainstream equipment for high-precision sample reduction. When reducing dry, fine-grained materials, a large amount of dust is easily generated during the material's fall and flow, which not only pollutes the working environment but also endangers the health of operators. Therefore, existing divider reduction cabinets are usually equipped with a negative pressure dust collection system to collect and treat the dust generated during the operation through negative pressure adsorption.

[0003] Currently, some binary separator reduction cabinets have dust collection components and dust-blocking and material guiding mechanisms that are mostly independently set and controlled. The dust collection fan is usually kept continuously running, and the negative pressure suction force remains constant. However, fine particles are lightweight and have weak gravity. A constant negative pressure suction force can easily cause significant traction interference to the material's falling trajectory, leading to the fine particles deviating from the preset grid distribution path or being excessively adsorbed to one side. This directly results in excessive reduction deviation, affecting sample preparation accuracy and the accuracy of test data. If a low suction force is maintained for a long time to avoid interfering with material distribution, residual dust cannot be effectively removed from the cabinet after feeding, resulting in poor dust removal effect and the risk of residual dust still escaping. At the same time, the independently set dust-blocking and material guiding mechanisms and dust collection components cannot achieve synchronized operation and need to be controlled and adjusted separately. This leads to problems such as cumbersome operation, complex control logic, and poor adaptability to working conditions, making it difficult to effectively balance reduction accuracy and dust removal effect, and failing to meet the requirements of efficient, accurate, and environmentally friendly sample preparation and reduction operations.

[0004] Therefore, there is an urgent need for a divider reduction cabinet, which can solve the problem that existing divider reduction cabinets cannot simultaneously achieve both reduction accuracy and dust removal effect. Summary of the Invention

[0005] The first objective of this invention is to provide a divider reduction cabinet that can solve the problem that existing divider reduction cabinets cannot simultaneously achieve both reduction accuracy and dust removal effect.

[0006] Based on the above concept, the technical solution adopted by this invention is as follows:

[0007] The splitter reduction cabinet includes:

[0008] A reduction cabinet, the top of which has a first inlet, and the side wall of the reduction cabinet along the X direction has a dust removal port.

[0009] The splitter body is installed inside the splitter cabinet and extends along the X direction.

[0010] A dust-blocking and material guiding assembly is housed within the reducing cabinet. The dust-blocking and material guiding assembly is positioned below the first inlet and above the separator body. The dust-blocking and material guiding assembly is used to guide the material falling into the first inlet to the separator body and to prevent dust generated during the material's descent from spreading upwards and towards the dust removal port.

[0011] The dust removal assembly includes an opening and closing component and a negative pressure suction component. The opening and closing component is arranged on the side wall of the reducing cabinet where the dust removal port is located to block or open the dust removal port. The negative pressure suction component is installed on the side wall where the dust removal port is located and is arranged opposite to the dust removal port. It is used to perform negative pressure suction and dust removal of the dust inside the reducing cabinet when the dust removal port is open.

[0012] The linkage component has one end connected to the power output end of the dust blocking and material guiding component, and the other end connected to the opening and closing component, so that the opening and closing component is driven synchronously when the dust blocking and material guiding component is activated, thereby realizing the linkage control of the degree of opening and closing of the dust blocking and material guiding component and the dust removal port.

[0013] As an optional solution for the divider reduction cabinet, the dust-blocking and material guiding assembly outputs rotational power, and the linkage assembly includes:

[0014] The first turntable is mounted on the power output end of the dust-blocking and material guiding assembly;

[0015] A first eccentric rod extends along the X direction and is mounted on the first turntable;

[0016] A crossbar extending along the Z direction, with a rectangular hole at one end;

[0017] A first gear, which is connected to the opening and closing element;

[0018] A rack extending in the Y direction, the top end of which is connected to the opposite end of the crossbar, and the rack meshing with the first gear.

[0019] As an optional solution for the divider reduction cabinet, the opening and closing mechanism includes:

[0020] Multiple blades, which extend along the Z direction, and the multiple blades cover the dust collection port;

[0021] Multiple rotating shafts extend along the Z-direction, each shaft passing through a corresponding blade and rotatably connected to the reduction cabinet, with the first turntable mounted on one end of the rotating shaft.

[0022] As an optional solution for the divider reduction cabinet, the dust-proof and material-guiding assembly includes:

[0023] Two rotating rods, both of which extend along the X direction and are arranged parallel to each other along the Z direction;

[0024] Two second gears are respectively installed at the ends of the two rotating rods, and the two second gears are meshed together;

[0025] The first driving component is installed on the inner wall of the split cabinet. The output end of the first driving component is connected to one of the two rotating rods. The first driving component can drive the connected rotating rod to rotate, and drive the other rotating rod to rotate synchronously in the opposite direction through the meshing second gear.

[0026] Multiple dust baffles are arranged at intervals along the circumference of the rotating rod and extend along the X direction. The dust baffles installed on two rotating rods can abut against each other to form a closed dust baffle structure.

[0027] As an optional solution for the divider reduction cabinet, the dust removal assembly also includes two arc-shaped seats, which are respectively installed on the inner wall of the top of the reduction cabinet. When the corresponding two dust baffles abut against each other, at least one dust baffle arranged on the same rotating rod can abut against the arc-shaped seat.

[0028] As an optional solution for the divider reduction cabinet, the divider reduction cabinet also includes a material unloading assembly, which includes:

[0029] The hopper is installed on top of the retractable cabinet;

[0030] The material discharge component is installed on the inner wall of the hopper. The material discharge component includes a first plane, two inclined planes and two second planes. Both sides of the first plane are provided with the inclined planes extending downward at an angle to the X direction. The side of the inclined plane away from the first plane is connected to the second plane. The second planes are provided with material discharge ports.

[0031] As an optional solution for the divider reduction cabinet, the unloading assembly also includes:

[0032] Second drive unit;

[0033] Transmission components;

[0034] Two bidirectional augers are arranged coaxially and spaced apart along the X-axis. The two bidirectional augers are rotatably connected to their respective side walls. The second drive unit is installed on the side wall of the hopper and is connected to one of the two bidirectional augers to drive the connected bidirectional auger to rotate.

[0035] Two second turntables are installed at one end of each of the two bidirectional augers;

[0036] Two second eccentric rods are mounted on the two second turntables respectively. The two second eccentric rods are coaxial and both are mounted on the transmission component.

[0037] As an optional solution for the divider reduction cabinet, the unloading assembly also includes:

[0038] A grating plate extends along the X direction and is installed in the silo. The grating plate has sliding holes, and sliding grooves extending along the Z direction are formed on the two side walls of the sliding holes along the X direction. The transmission member passes through the sliding holes and slides into the sliding grooves. The transmission member is used to drive the grating plate to reciprocate along the Y direction.

[0039] A limiting rod extends along the Y direction and is fixed to the bottom of the material dropper. The limiting rod passes through the grid plate and slides with the grid plate.

[0040] As an optional solution for the divider reduction cabinet, the divider reduction cabinet also includes a receiving component, which is arranged below the discharge port of the divider body and is slidably inserted into the reduction cabinet.

[0041] The second objective of this invention is to provide a method for using a material divider cabinet, which can solve the problem of balancing the accuracy of material reduction with dust pollution control.

[0042] The method for using the splitter reduction cabinet includes the following steps:

[0043] S1: Stir the material to be reduced evenly and add it symmetrically into the silo along both sides;

[0044] S2: Start the second drive unit to drive the bidirectional auger to rotate. The material in the hopper is conveyed to the center through the spiral blades. The material falls onto the grid plate. At the same time, the second turntable rotates synchronously with the bidirectional auger. The second eccentric rod pulls the grid plate to reciprocate along the Y direction, spreading the falling material evenly. The material passes through the grid plate in a dispersed state and falls onto the closed dust baffle plate for temporary storage.

[0045] S3: Activate the first drive unit, which drives the rotating rod and the dust baffle to rotate and open synchronously. The material is temporarily stored and falls vertically into the body of the separator. When the rotating rod rotates, it drives the opening and closing parts through the linkage component to reduce the opening and closing degree of the dust removal port and reduce the negative pressure suction of the negative pressure suction component. The material is divided into equal amounts through the staggered grid of the body of the separator under low suction. The divided material falls into the receiving parts on both sides respectively. At the same time, the low negative pressure continuously adsorbs the dust generated during the falling process of the material.

[0046] S4: After the material falls completely into the body of the separator, the first driving component continues to drive the rotating rod to rotate. Through the meshing transmission of the second gear, the dust baffle plate simultaneously abuts and closes to block the material. At the same time, the linkage component drives the opening and closing component to move in the opposite direction, increasing the opening and closing degree of the dust removal port and enhancing the negative pressure suction to efficiently adsorb and clean the residual dust inside the reducing cabinet and the inner wall of the separator body.

[0047] S5: After the dust is cleaned, turn off the first drive unit, the second drive unit and the negative pressure dust suction unit to complete one reduction process, pull out the receiving part, take out the diverted material, check that there is no dust accumulation inside the reduction cabinet, and then reset the dust baffle and the opening and closing part.

[0048] The beneficial effects of this invention are as follows:

[0049] This invention proposes a dividing and reducing cabinet for a two-part separator. A first inlet is located at the top of the cabinet, and a dust removal port is located on one side wall along the X-direction. The two-part separator body is installed inside the cabinet, extending along the X-direction. A dust-blocking and material-guiding assembly is housed within the cabinet, positioned below the first inlet and above the two-part separator body. This assembly guides the material falling through the first inlet to the two-part separator body and prevents dust generated during the material's descent from spreading upwards and towards the dust removal port. The dust removal assembly includes an opening / closing component and a negative pressure suction component. The opening / closing component is located on the side wall where the dust removal port is located to block or open the port. The negative pressure suction component is installed on the side wall where the dust removal port is located and is positioned corresponding to the port. It is used to perform negative pressure suction of dust inside the dividing and reducing cabinet when the dust removal port is open. One end of a linkage component is connected to the power output end of the dust-blocking and material-guiding assembly, and the other end of the linkage component is connected to... The opening and closing mechanism is connected so that the dust-blocking and material-guiding components move synchronously, enabling the linkage control of the opening and closing degree of the dust-blocking and material-guiding and dust removal ports. It automatically matches the corresponding dust-blocking and material-guiding state to change the dust removal suction power, accurately distinguishing and adapting to the work requirements of the reduction and dust cleaning stages. It provides appropriate suction power during the material's gravity-fall reduction process and switches to high-efficiency dust cleaning suction power after feeding. It truly realizes intelligent and staged coordinated operation of the entire process of reduction and dust removal, avoiding excessive traction of light and fine particles due to excessive suction power, which can cause materials to deviate from the preset grid, exceed the reduction deviation standard, and distort test data. It also avoids the problem of residual dust in the cabinet after feeding cannot be effectively removed due to deliberately maintaining low suction power, resulting in dust emission that pollutes the environment and endangers the health of operators. At the same time, it can also avoid the defects of asynchronous adjustment, cumbersome operation, and complex control logic caused by independent control of dust removal and dust blocking mechanisms.

[0050] This invention also proposes a method for using a two-part separator reducing cabinet to achieve intelligent, phased reducing and dust removal of materials such as coal and minerals. Through a complete process of material mixing, uniform spreading, temporary storage, low-suction equal-volume diversion and reducing, and high-suction cleaning of residual dust after reducing, it achieves the integration of equal-volume material diversion and efficient dust treatment. At the same time, the linkage mechanism realizes the dynamic adaptation of dust blocking and material guiding with dust removal suction, ensuring the precise connection of each stage of reducing and dust cleaning. The low-suction environment avoids the displacement of light and fine particles, ensuring the authenticity of test data, and the high-suction can quickly remove residual dust inside the equipment after reducing, improving the cleanliness of the working environment and reducing dust pollution.

[0071] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0072] This embodiment provides a divider reduction cabinet, such as... Figures 1-3 As shown, in this embodiment, the divider reduction cabinet includes a reduction cabinet 1, a divider body 2, a dust-blocking and material-guiding assembly 3, a dust removal assembly 4, and a linkage assembly 5. The top of the reduction cabinet 1 has a first inlet, and a dust removal port is provided on one side wall along the X direction. The divider body 2 is installed inside the reduction cabinet 1 and extends along the X direction. The dust-blocking and material-guiding assembly 3 is housed inside the reduction cabinet 1, positioned below the first inlet and above the divider body 2. The dust guiding assembly 3 guides the material falling into the first inlet to the separator body 2 and prevents dust generated during the material's descent from spreading upwards and towards the dust removal port. The dust removal assembly 4 includes an opening / closing component 41 and a negative pressure suction component 42. The opening / closing component 41 is arranged on the side wall of the reducing cabinet 1 where the dust removal port is located to block or open the dust removal port. The negative pressure suction component 42 is installed on the side wall where the dust removal port is located and is arranged corresponding to the dust removal port. It is used to perform negative pressure suction and dust removal of the dust inside the reducing cabinet 1 when the dust removal port is open. The linkage assembly 5... One end is connected to the power output end of the dust-blocking and material-guiding component 3, and the other end of the linkage component 5 is connected to the opening and closing component 41. This allows the opening and closing component 41 to move synchronously when the dust-blocking and material-guiding component 3 is activated, achieving linkage control of the degree of opening and closing of the dust-blocking and material-guiding and dust removal ports. It automatically matches the corresponding dust-blocking and material-guiding state to change the dust removal suction power, accurately distinguishes and adapts to the work requirements of the reduction operation stage and the dust cleaning stage. It provides appropriate suction power during the material reduction process under gravity, and switches to high-efficiency dust removal suction power after feeding. It truly realizes the intelligent and phased collaborative operation of the entire process of reduction and dust removal, avoiding excessive traction of light and fine particles due to excessive suction power, which can cause materials to deviate from the preset grid, exceed the reduction deviation standard, and cause distorted test data. It also avoids the problem of residual dust in the cabinet after feeding cannot be efficiently removed due to deliberately maintaining low suction power, dust escape and pollute the environment, and endanger the health of operators. At the same time, it can also avoid the defects of asynchronous adjustment, cumbersome operation, and complex control logic caused by independent control of dust removal and dust blocking mechanisms.

[0073] Preferably, such as Figures 1-4As shown, in this embodiment, the dust-blocking and material-guiding assembly 3 outputs rotational power, and the linkage assembly 5 includes a first turntable 51, a first eccentric rod 52, a crossbar 53, a first gear 55, and a rack 54. The first turntable 51 is mounted on the power output end of the dust-blocking and material-guiding assembly 3. The first eccentric rod 52 extends along the X direction and is mounted on the first turntable 51. The crossbar 53 extends along the Z direction, and a rectangular hole is provided at one end of the crossbar 53. The first gear 55 is connected to the opening and closing member 41. The rack 54 extends along the Y direction, and the top end of the rack 54 is connected to the opposite end of the crossbar 53. The rack 54 meshes with the first gear 55. The dust-blocking and material-guiding assembly 3 outputs rotational power to drive the first turntable 51 to rotate. The first eccentric rod 52 on the first turntable 51 moves in a circular motion with the turntable, driving the crossbar 53 to reciprocate along the Y direction through the rectangular hole. The crossbar 53 drives the rack 54 extending along the Y direction to move synchronously. As the material moves downward, the rack 54 meshes with the first gear 55, converting the linear lifting motion into the rotational motion of the first gear 55. The first gear 55 then drives the opening and closing component 41 to move synchronously, thereby converting the rotational motion of the dust-blocking and material-guiding assembly 3 into eccentric oscillation, linear lifting, and gear and rack 54 meshing motion in sequence. This stably and synchronously drives the opening and closing component 41 to perform corresponding actions, accurately realizing the mechanical linkage control between the dust-blocking and material-guiding action and the opening and closing degree of the dust removal port. It automatically adjusts the opening and closing size of the dust removal port and the negative pressure suction according to different stages of the reduction operation, completing the seamless switching between the reduction operation and dust cleaning. There is no need to add additional complex electrical components such as electrical control sensors and PLC controllers. The structure is simple and reliable, the transmission is stable, and the response is timely. It can directly rely on the power of the dust-blocking and material-guiding assembly 3 to realize the follow-up control of the opening and closing of the dust removal port, and can match the optimal negative pressure suction in real time according to the material falling and the dust blocking status.

[0074] Preferably, such as Figures 1-5 As shown, in this embodiment, the opening / closing component 41 includes multiple blades 411 and multiple rotating shafts 412. The blades 411 extend along the Z-direction and cover the dust collection port. The rotating shafts 412 extend along the Z-direction, pass through the corresponding blades 411, and are rotatably connected to the reducing cabinet 1. The first turntable 51 is installed at one end of the rotating shaft 412, which can precisely and continuously adjust the opening size and opening angle of the dust collection port. This, combined with the linkage component 5, achieves synchronized opening control with the dust-blocking and material-guiding component 3, thereby enabling precise and continuous adjustment of the reducing operation and... At different stages of dust cleaning, the system automatically matches the corresponding size of the negative pressure suction channel, realizing the staged and adaptive adjustment of dust removal suction power and working conditions. The blade 411 type opening and closing part 41 has a simple structure, flexible rotation, and good sealing performance. The rotating shaft 412 provides stable and reliable support. The blade 411 fits tightly with the dust removal port, which can form a precise and controllable weak negative pressure at a small opening and provide a strong negative pressure for efficient dust removal at a large opening. The adjustment process is smooth and without jamming, realizing a smooth transition between different suction power ranges and improving the accuracy of the coordinated control of dust reduction and dust removal.

[0075] Optionally, such as Figures 1-5 As shown, in this embodiment, both blades 411 and rotating shaft 412 are provided with seven blades 411, and the seven blades 411 are arranged along the Y direction. In other embodiments, both blades 411 and rotating shaft 412 may be provided with one, two, three, four, five, six, eight, nine, or ten blades 411, etc., and the quantity is not limited.

[0076] Preferably, such as Figures 1-6 As shown, in this embodiment, the dust-blocking and material-guiding assembly 3 includes two rotating rods 31, two second gears 32, a first driving member, and multiple dust-blocking plates 33. The two rotating rods 31 extend along the X-direction and are arranged parallel to each other along the Z-direction. The two second gears 32 are respectively installed at the ends of the two rotating rods 31 and mesh with each other. The first driving member is installed on the inner wall of the distribution cabinet 1, and its output end is connected to one of the two rotating rods 31. The first driving member can drive the connected rotating rod 31 to rotate and, through the meshing second gears 32, drive the other rotating rod. The rod 31 rotates synchronously in opposite directions, and multiple dust baffles 33 are arranged at intervals along the circumference of the rotating rod 31. The dust baffles 33 extend along the X direction. The dust baffles 33 installed on the two rotating rods 31 can abut against each other to form a closed dust baffle structure, which can stably guide the material falling from the feed port to the lower separator body 2, and actively block the upward diffusion of dust during the material falling and shrinking process. At the same time, the opening and closing state of the dust baffles 33 can be adjusted according to the operation stage. In conjunction with the linkage component 5, the coordinated action of dust baffle and material guiding and dust removal port opening and closing can be realized to complete the stable switching between the shrinking operation and dust cleaning operation.

[0077] Preferably, in this embodiment, one end of the two rotating rods 31 that is not connected to the first driving member is connected to the first turntable 51. In other embodiments, the first turntable 51 can be connected to any of the power output ends of the dust-blocking and material-guiding assembly 3 that can output rotational power.

[0078] Preferably, such as Figures 1-7 As shown, in this embodiment, the dust removal component 4 also includes two arc-shaped seats 34, which are respectively installed on the inner wall of the top of the reducing cabinet 1. When the corresponding two dust baffles 33 abut against each other, at least one dust baffle 33 arranged on the same rotating rod 31 can abut against the arc-shaped seat 34. Through the abutment cooperation between the dust baffle 33 and the arc-shaped seat 34, while the dust baffle 33 closes to form a closed dust baffle structure, the gap between the upper part of the dust baffle 33 and the inner wall of the top of the reducing cabinet 1 is sealed, further improving the upper sealing area. Together with the dust baffle and material guiding component 3, a fully enclosed sealed dust baffle space is formed, improving the top sealing effect and structural operation stability, and strengthening the ability to block dust from escaping upwards. The arc-shaped structure can follow the rotation trajectory of the dust baffle 33 to achieve a smooth transition abutment without interfering with normal opening and closing actions.

[0079] Preferably, such as Figures 1-8 As shown, in this embodiment, the divider reduction cabinet also includes a material unloading assembly 6. The material unloading assembly 6 includes a hopper 61 and a material unloading component 62. The hopper 61 is installed on the top of the reduction cabinet 1, and the material unloading component 62 is installed on the inner wall of the hopper 61. The material unloading component 62 includes a first plane 621, two inclined surfaces 622, and two second planes 623. Both sides of the first plane 621 are provided with inclined surfaces 622 extending downward at an angle to the X direction. The inclined surfaces 622 are located away from the first plane 621. The material is connected to the second plane 623 on the side. The second plane 623 has a material drop port. The material entering the hopper 61 can be initially collected by the first plane 621, then evenly guided and dispersed along the inclined plane 622, and finally fall stably, orderly and evenly into the dust-blocking and material guiding component 3 and the separator body 2 through the material drop port on the second plane 623. This realizes the continuous, uniform and controllable material drop and conveying from the hopper 61 to the separator, providing a stable and uniform material supply basis for the subsequent separator reduction cabinet operation.

[0080] Preferably, such as Figures 1-8 As shown, in this embodiment, the material feeding assembly 6 further includes a second driving member 63, a transmission member 64, two bidirectional augers 65, two second turntables 66, and two second eccentric rods 67. The two bidirectional augers 65 are coaxially arranged and spaced apart along the X-axis. The two bidirectional augers 65 are rotatably connected to their respective side walls. The second driving member 63 is installed on the side wall of the hopper 61 and is connected to one of the two bidirectional augers 65 to drive the connected bidirectional auger 65 to rotate. A second turntable 66 is installed at one end of each of the two bidirectional augers 65. A second eccentric rod 67 is installed on each of the two second turntables 66. The two second eccentric rods 67 are coaxial and are both installed on the transmission member 64. The material passes through the material feeding assembly 63. 2. After entering, the second driving component 63 drives one of the bidirectional augers 65 to rotate. This bidirectional auger 65 then drives the other bidirectional auger 65 synchronously through the second turntable 66, the second eccentric rod 67, and the transmission component 64. The two bidirectional augers 65, which are coaxial along the X-axis and spaced apart, perform lateral stirring, pushing, and dispersion of the material. With the reciprocating disturbance of the transmission component 64, the material is evenly and continuously fed to the discharge port and falls, completing a stable and uniform automated material discharge process. This provides stable and uniform material feeding conditions for the dividing cabinet below. The bidirectional augers 65 achieve forced dispersion and lateral uniform distribution of the material, improving the material flowability and uniformity of the distribution. At the same time, in conjunction with the dust blocking and material guiding structure below, the dust removal linkage structure further improves the dividing accuracy and the level of automation of the operation.

[0081] Preferably, such as Figures 1-8As shown, in this embodiment, the material feeding assembly 6 further includes a grating plate 68 and a limiting rod 69. The grating plate 68 extends along the X direction and is installed in the hopper 61. The grating plate 68 has a sliding hole, and sliding grooves extending along the Z direction are formed on the two side walls of the sliding hole along the X direction. The transmission member 64 passes through the sliding hole and slides into the sliding groove. The transmission member 64 is used to drive the grating plate 68 to reciprocate along the Y direction. The limiting rod 69 extends along the Y direction and is fixed to the bottom of the material feeding component 62. The limiting rod 69 passes through the grating plate 68 and slides with the grating plate 68. In a coordinated manner, after the material enters the hopper 61 through the discharge component 62, the transmission component 64, driven by the second turntable 66 and the second eccentric rod 67, drives the grid plate 68 extending along the X direction to reciprocate along the Y direction. At the same time, the limiting rod 69 slides and limits the grid plate 68, so that the grid plate 68 evenly distributes the falling material, breaks up the lumpy material, disperses the concentrated flow, and stably conveys it to the lower discharge port, realizing the uniform discharge of the material and avoiding the problem of grid blockage and shrinkage segregation caused by lumps and clumps of material directly entering the separator.

[0082] Optionally, such as Figures 1-5 As shown, in this embodiment, two limiting rods 69 are provided, and the two limiting rods 69 are respectively located at both ends of the grid plate 68 along the X direction. In other embodiments, there may be one, three, four, five or six limiting rods 69, etc.

[0083] Preferably, such as Figures 1-3 As shown, in this embodiment, the divider reduction cabinet also includes a receiving component 7. The receiving component 7 is arranged below the discharge port of the divider body 2. The receiving component 7 is slidably inserted into the reduction cabinet 1, which can stably receive various materials after being reduced by the divider body 2. The receiving component 7 can be quickly removed by sliding and pulling, so as to facilitate the timely removal of the material sample after reduction, avoid the accumulation and residue of materials in the cabinet, simplify the sampling operation process, and improve the convenience and efficiency of the reduction operation.

[0084] This embodiment also provides a method for using the splitter reduction cabinet. Using the splitter reduction cabinet provided in this embodiment, such as... Figures 1-8 As shown, in this embodiment, the method of using the divider reduction cabinet includes the following steps:

[0085] S1: Stir the material to be reduced evenly and add it symmetrically into the hopper 61 along both sides of the hopper 61;

[0086] S2: Start the second drive unit 63 to drive the bidirectional auger 65 to rotate. The material in the hopper 61 is conveyed to the center through the spiral blades. The material falls to the grid plate 68. At the same time, the second turntable 66 rotates synchronously with the bidirectional auger 65. The second eccentric rod 67 pulls the grid plate 68 to move back and forth along the Y direction, so that the falling material is evenly spread and the material passes through the grid plate 68 in a dispersed state and falls onto the closed dust baffle 33 to complete temporary storage.

[0087] S3: Start the first driving component, which drives the rotating rod 31 and the dust baffle 33 to rotate and open synchronously. The temporarily stored material falls vertically into the body of the separator 2. When the rotating rod 31 rotates, it drives the opening and closing component 41 through the linkage component 5 to reduce the opening and closing degree of the dust removal port and reduce the negative pressure suction force of the negative pressure suction component 42. The material is divided into equal amounts through the staggered grid of the body of the separator 2 under low suction environment. The divided material falls into the receiving components 7 on both sides respectively. At the same time, the low negative pressure continuously adsorbs the dust generated during the falling process of the material.

[0088] S4: After the material has completely fallen into the body 2 of the separator, the first driving component continues to drive the rotating rod 31 to rotate. Through the meshing transmission of the second gear 32, the dust baffle 33 simultaneously abuts against and closes the material. At the same time, the linkage component 5 drives the opening and closing component 41 to move in the opposite direction, increasing the opening and closing degree of the dust removal port, enhancing the negative pressure suction, and efficiently adsorbing and cleaning the residual dust inside the reducing cabinet 1 and the inner wall of the separator body 2.

[0089] S5: After the dust is cleaned, turn off the first drive unit, the second drive unit 63 and the negative pressure dust suction unit 42 to complete one reduction process. Pull out the receiving unit 7, take out the diverted material, check that there is no dust accumulation inside the reduction cabinet 1, and then reset the dust baffle 33 and the opening and closing unit 41.

[0090] The aforementioned two-part separator cabinet enables intelligent, phased separation and dust removal of materials such as coal and minerals. Through a complete process involving material mixing, uniform spreading, temporary storage, low-suction equal-volume separation, and high-suction cleaning of residual dust after separation, it achieves integrated material equal-volume separation and efficient dust treatment. Simultaneously, a linkage mechanism dynamically adapts dust blocking and material guiding to the dust removal suction power, ensuring precise connection between each stage of separation and dust removal. This guarantees the accuracy and uniformity of material separation, prevents the displacement of light, fine particles through a low-suction environment to ensure the authenticity of test data, and rapidly removes residual dust from the equipment after separation through high suction, improving the cleanliness of the working environment and reducing dust pollution. Furthermore, automated process control and linkage adjustment simplify operation steps, improve the efficiency of separation operations, reduce manual intervention costs, and achieve a balance between high-efficiency operation and environmental protection requirements.
