Description

Technical Field

[0001] This utility model relates to the field of dynamic mixing and processing technology of various materials, and in particular to a dynamic mixing and pulverizing production system that improves storage, quantitative metering and pulverization. Background Technology

[0002] Existing mixing and crushing production systems typically involve conveying various materials via conveyor belts or manually transporting them to the top of a hopper for feeding. The materials then directly enter the hopper for crushing and mixing. Because the conveyor belts are angled, the system occupies a large space. Furthermore, dust and impurities often accumulate when materials are added to the hopper, making timely removal difficult. Most existing mixing and crushing production systems lack automatic material feeding devices; some rely on manual adjustment of the conveyor belt's output position, which is cumbersome. Current technologies fail to adequately address how to quickly feed materials into the mixing and crushing system while simultaneously optimizing its layout within limited space. Utility Model Content

[0003] This invention provides a novel dynamic mixing and pulverizing production system that improves storage, quantitative measurement, and mixing.

[0004] To achieve the above objectives, this utility model provides a dynamic mixing and pulverizing production system for lifting, storing, and metering materials, including a feeder, a dust collection device, a vertical bucket elevator, a spiral distributor, a silo, a dynamic metering feeder, a spreading conveyor, a pulverizer, and an electrical control cabinet. The vertical bucket elevator has a feeder at its bottom, a dust collection device connected to its side wall, and its upper part connected to the spiral distributor via a discharge pipe. The spiral distributor has at least one discharge port at its bottom, with a valve at the discharge port, and the spiral distributor is connected to the silo via the valve. The silo has a dynamic metering feeder connected to its bottom, and a spreading conveyor located below the dynamic metering feeder, with its output end connected to the pulverizer. The electrical control cabinet is connected to the vertical bucket elevator, the dust collection device, the spiral distributor, the discharge port valve, the dynamic metering feeder, the horizontal spreading conveyor, and the pulverizer. The spiral distributor includes a motor and a horizontal spiral propulsion rod, with the motor positioned outside the horizontal spiral propulsion rod, controlling its rotation.

[0005] Furthermore, a vibrator is also provided at the bottom of the feeder hopper.

[0006] Furthermore, the feed rates of the vibrator, vertical bucket elevator, and spiral feeder are the same.

[0007] Furthermore, a screen is installed between the dust collection device and the vertical bucket elevator, and the screen aperture is smaller than the outer diameter of the material.

[0008] Furthermore, the dynamic metering feeder includes a metering screw, a drive reduction power source, a coupling, a feed pipe, and a discharge port. The feed pipe is connected to the bottom of the hopper, and the electrical control cabinet is connected to the dynamic metering feeder.

[0009] Furthermore, the material conveyor is connected to the discharge port at one end and to the crusher at the other end.

[0010] Furthermore, the material conveyor is a sealing mechanism.

[0011] The advantages of this utility model compared to the prior art are:

[0012] The vertical bucket elevator design reduces the space required for material lifting and feeding; the horizontally positioned spiral feeder, used in conjunction with the vertical bucket elevator, simplifies the dynamic mixing and crushing production system, resulting in a smaller overall footprint and more precise feeding control; and the dust collection device installed on the side wall of the vertical bucket elevator effectively removes dust during material lifting, further simplifying the system structure and reducing its footprint.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment provides a dynamic mixing and pulverizing production system for lifting, storing, and metering materials, including a feeder 1, a dust collection device 2, a screen 2.1, a vertical bucket elevator 3, a spiral distributor 4, a hopper 5, a dynamic metering feeder 6, a material spreading conveyor 7, a pulverizer 8, and an electrical control cabinet 9; the feeder 1 is installed at the bottom of the vertical bucket elevator 3, the dust collection device 2 is connected to the side wall of the vertical bucket elevator 3, and the upper part of the vertical bucket elevator 3 is connected to the spiral distributor 4 through a discharge pipe 17; the spiral distributor 4 has at least one discharge port at its bottom, and a valve 16 is installed at the discharge port, through which the spiral distributor 4... Valve 16 is connected to silo 5; the bottom of silo 5 is connected to dynamic metering feeder 6, and a spreading conveyor 7 is installed below dynamic metering feeder 6. The output end of spreading conveyor 7 is connected to crusher 8; the electrical control cabinet 9 is connected to vertical bucket elevator 3, dust collection device 2, spiral distributor 4, valve 16, dynamic metering feeder 6, horizontal spreading conveyor 7, and crusher 8 respectively; the spiral distributor 4 includes a motor 4.1 and a horizontal spiral push rod 4.2. The motor 4.1 is located outside the horizontal spiral push rod 4.2, and controls the rotation of the horizontal spiral push rod 4.2 through the motor 4.1. The setting of vertical bucket elevator 3 makes the material lifting and feeding space smaller; the design of spiral distributor 4 makes the feeding structure simpler and occupies less space; the combination of vertical bucket elevator 3 and spiral distributor 4 makes feeding more accurate. Thus, it effectively solves the technical problems of large space occupation and complex structure in the existing mixed crushing production system.

[0018] For example, the bottom of the feeder 1 is also provided with a vibrator 15. The vibrator 15 makes it easier for the material to be lifted and transported by the vertical bucket elevator 3, effectively preventing material residue.

[0019] For example, the oscillator 15, the vertical bucket elevator 3, and the spiral feeder 4 have the same feeding rate, which effectively prevents material blockage and agglomeration as well as uneven feeding.

[0020] For example, a screen 2.1 is provided between the dust collection device 2 and the vertical bucket elevator 3. The aperture of the screen 2.1 is smaller than the outer diameter of the material, so that dust and powder can pass through the screen 2.1, while the material will not pass through the screen 2.1, thereby making the dust removal process have less impact on the material.

[0021] For example, the dynamic metering feeder 6 includes a metering screw 6.1, a drive reduction power source 6.2, a coupling 6.3, a feed pipe 6.4, and a discharge port 6.5. The discharge pipe 6.4 is connected to the bottom of the hopper 5, and the electrical control cabinet 9 is connected to the dynamic metering feeder 6. By controlling the rotation of the drive reduction power source 6.2, the coupling 6.3 is driven to rotate, which in turn drives the metering screw 6.1 to rotate, thereby feeding the material in the hopper 5 through the discharge port 6.5. The electrical control cabinet 9 precisely controls the material feeding speed and quantity by controlling the rotation speed and number of revolutions of the drive reduction power source 6.2, resulting in more precise control.

[0022] For example, one end of the material spreading conveyor 7 is connected to the discharge port 6.5, and the other end is connected to the feed port of the crusher 8.

[0023] For example, the material conveyor 7 is a sealing mechanism to prevent dust caused by material falling during the feeding process of the dynamic metering feeder 6.

[0024] In another embodiment of this utility model, such as Figure 1 and Figure 2As shown, the system includes a feeder 1, a dust collection device 2, a screen 2.1, a vertical bucket elevator 3, a spiral distributor 4, a hopper 5, a dynamic metering feeder 6, a material spreading conveyor 7, a crusher 8, an electrical control cabinet 9, a cyclone separator 10, a small material mixing bin 11, a dust collector 12, a silencer 13, an induced draft fan 14, a vibrator 15, a valve 16, a discharge pipe 17, and a lifting pipe 18. Materials are manually fed into the feeder 1. A vibrator 15 is installed below the hopper of the feeder 1. The vibration frequency of the vibrator 15 is adjusted to match the feeding rate of the vertical bucket elevator 3. As the buckets on the elevator 3 pass the bottom of the feeder 1, they lift the material through the buckets. The buckets are driven by a reduction gear drive chain to lift the material into the upper discharge pipe 17. An opening is located on the side wall of the vertical bucket elevator 3, and a dust collection device 2 is installed. A screen 2.1 is installed between the dust collection device 2 and the side wall of the vertical bucket elevator 3. The dust collection device 2 includes a dust collection fan and a dust collection bag. The fan suction draws dust and particulate matter into the dust collection bag for collection. The material passes through the bottom of the discharge pipe 17 and enters the spiral distributor 4, which is a water-cooled device controlled by a motor 4.1. The horizontal spiral propeller 4.2 structure is driven by a motor 4.1 to rotate, thereby driving the material to the corresponding material bin 5. A valve 16 is installed on the upper part of each material bin 5. When material needs to be fed into a particular material bin 5, the valve 16 is opened via the electrical control cabinet 9. The material, pushed by the horizontal spiral propeller 4.2, passes through the valve 16 and enters the material bin 5 by its own gravity, thus achieving the feeding of the corresponding material bin 5. Each material bin 5 is connected to a dynamic metering feeder 6 at its bottom. The dynamic metering feeder 6 consists of a metering screw 6.1 and a drive reducer. The system consists of a power source 6.2, a coupling 6.3, an inlet pipe 6.4, and an outlet 6.5. The drive and reduction power source 6.2 is connected to the screw 6.1 via the coupling 6.3. The inlet pipe 6.4 is located on the upper part of the dynamic metering feeder 6 and connects to the outlet of the hopper 5. The outlet 6.5 connects to the inlet of the spreading conveyor 7. The diameter and pitch of the screw 6.1 are designed according to the hourly output to adapt to the continuous conveying and metering of specific materials. When the electrical control cabinet 9 gives a signal, it pushes the material to the spreading conveyor 7, ensuring that the content of various materials in each section meets the formula requirements. The spreading conveyor 7 is a sealed structure, and its outlet is directly connected to the inlet of the crusher 8 via a hose. The outer shell of the crusher 8 is equipped with a water-cooled cooling jacket (not shown in the figure) to achieve a cooling function. The discharge port of the crusher 8 is connected to the inlet of the cyclone separator 10 through the lifting pipe 18. The upper end of the cyclone separator 10 is connected to the dust collection box 12, which is a pulse dust collector. The end of the pulse dust collector 12 is connected to the induced draft fan 14 and the silencer 13. The silencer 13 reduces the noise of the induced draft fan 14.

[0025] Example: The working environment of the dynamic mixing and pulverizing production system for improving storage and metering described in this utility model is as follows:

[0026] 1. For indoor installation and use, the ground flatness should not exceed 2mm / square meter;

[0027] 2. Ambient humidity: Relative humidity ≤ 85%;

[0028] 3. Ambient temperature: 10-40℃;

[0029] 4. Power supply: Three-phase AC380V±10%, power frequency 50Hz±1Hz;

[0030] 5. Compressed air pressure: greater than 0.7 MPa, and no more than 3 meters away from the point of use.

[0031] 6. Ground bearing capacity: 700 kg / m².

[0032] Process: Turn on the dust collection device → Set the feed bin number → Manually feed the corresponding raw material into the feeder → Bucket elevator quickly lifts the material → Raw material passes through the transition hopper → Enters the horizontal spiral distributor → Enters the corresponding bin according to the settings.

[0033] Pre-set the proportion of raw materials in each hopper in the product → After starting the crusher, the preceding modules run separately → The dynamic metering feeder continuously feeds materials according to the set value → Quantitatively feeds and layers the materials onto the closed material conveyor → The content of various materials is uniform in each section.

[0034] Dust-collecting pulverizer unit: Replace the screen in advance → The raw materials with uniform content are fed into the pulverizer → The pulverizer main unit current is acquired → The main unit current signal is amplified to control the speed of the closed horizontal conveyor and the dynamic metering feeder → The pulverization efficiency is maximized → The pulverized finished product enters the cyclone separator for temporary storage → The ultrafine powder enters the dust collection box → Clean air enters the fan → It is discharged through the silencer.

[0035] The pulverized finished product is temporarily stored in a cyclone separator → it is connected to the customer's existing mixer → the pulverized finished powder enters the mixer → trace elements and liquids are automatically added according to the settings → after being mixed evenly, it is discharged into a screw conveyor.

[0036] For example, the feeding speed of the oscillator 15 needs to meet 15 m³ / h, and the feeding speed is adjusted by adjusting the oscillation frequency.

[0037] ①The vertical bucket elevator 3 adopts a Z-shaped structure.

[0038] ② The lifting speed of the vertical bucket elevator 3 must meet 15m³ / h.

[0039] ③ Vertical bucket elevator 3 Its structure is a stainless steel sheet metal frame, with a reduction power source installed at the bottom to drive the chain movement. The buckets and the chain are connected by shafts, thereby realizing the entire lifting process of horizontal material receiving -- vertical -- horizontal -- flipping and dumping -- horizontal -- vertical -- horizontal -- flipping and horizontal material receiving.

[0040] ④ This equipment operates stably, without noise or residue, and through special modifications, it has completely solved the problem of dust flying.

[0041] Spiral feeder 4:

[0042] ①The spiral feeder 4 adopts a spiral tube structure, which drives the raw material at the inlet to the corresponding outlet.

[0043] ② The horizontal spiral propeller 4.2 is driven by the motor 4.1 to rotate. The inlet of each hopper is controlled by the pneumatic control element. When it is necessary to feed material into the hopper 5, the valve 16 is automatically opened. When the horizontal spiral propeller 4.2 drives the raw material to the position of the valve 16, it settles into the hopper 5 by its own gravity, thereby realizing the feeding of the corresponding hopper.

[0044] ③ The conveying speed of the spiral feeder 4 must meet the feeding rate of 15m³ / h.

[0045] The preferred number of hoppers 5 is 8. The thickness of each hopper 5 is 1160mm. The width varies depending on the volume. The bottom of the hopper 5 is tapered to a greater than the angle of repose to facilitate docking with the dynamic metering feeder 6.

[0046] The material feeding conveyor 7 adopts a single-type structure, with complete sealing at the top, bottom, front, and back. Its upper cover has 8 feeding ports connected to the dynamic metering feeder 6, and the lower right end cover has a receiving outlet that directly connects to the crusher 8. This achieves delayed material receiving at the 8 feeding ports, horizontal conveying, horizontal material falling and mixing, and uniform entry into the crushing hopper.

[0047] The working principle of this utility model:

[0048] Material enters the feeder 1 and then falls to the bottom of the feeder 1 through the vibrator 15. Then, the vertical bucket elevator 3 lifts the material under the control of the electrical control cabinet 9. During the lifting process, the material is treated by the dust collection device 2. After dust removal, the material enters the upper drop pipe 17 through the vertical bucket elevator 3 and then enters the spiral distributor 4. The motor 4.1 of the spiral distributor 4 drives the horizontal spiral push rod 4.2 to rotate, thereby conveying the material laterally. When it is necessary to add material to a hopper 5, the valve 16 at the top of the hopper 5 is opened by controlling the electrical control cabinet 9, and the material falls into the hopper 5 from the valve 16. When crushing and batching are required, the dynamic metering feeder 6 is controlled by the electrical control cabinet 9 to feed the material. The material enters the spreading conveyor 7 through the discharge port 6.5 of the dynamic metering feeder 6. The material is then conveyed by the spreading conveyor 7 into the crusher 8 for crushing. The crushed material enters the cyclone separator 10 through the lift pipe 18. The material falls under the action of gravity, while the dust in the material, being lighter, is drawn into the dust collector 12 connected to the upper part of the cyclone separator 10 by suction to remove dust. The induced draft fan 14 at the rear end of the dust collector 12 provides suction for the material in the dust collector 12. The silencer 13 on the induced draft fan 14 is used to reduce noise.

[0049] The vertical bucket elevator 3 reduces the space required for material lifting and feeding; the horizontally positioned spiral feeder 4, used in conjunction with the vertical bucket elevator 3, simplifies the dynamic mixing and crushing production system, reduces its overall space requirement, and improves the precision of feeding control; and the dust collection device 2 installed on the side wall of the vertical bucket elevator 3 effectively removes dust during the material lifting process, further simplifying the overall system structure and reducing its space requirement.

Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
