Description

Technical Field

[0001] This utility model relates to the field of dispersant technology, and in particular to a dispersant device for breaking up spherical or blocky potassium sulfate materials produced by the reaction of sulfuric acid and potassium chloride. Background Technology

[0002] During the reaction of sulfuric acid and potassium chloride, a large amount of spherical or lumpy material will inevitably be produced.

[0003] The current industry practice is to directly feed uncrushed spherical or blocky materials into a tubular chain conveyor for transport and subsequent processing. This existing technology has several drawbacks:

[0004] (1) Severe equipment wear and tear: Spherical and blocky materials are large in volume and have high hardness. During the operation of the tubular chain machine, they will collide and rub violently with the chain, scraper, pipe and other components of the tubular chain machine. For example, when a certain enterprise uses the existing process, the chain of the tubular chain machine needs to be replaced on average every 3 months, the monthly damage rate of the scraper reaches 20%, and a large number of deep scratches appear on the inner wall of the pipe, which seriously affects the service life of the equipment and greatly increases the equipment maintenance cost and downtime for repair.

[0005] (2) Low production efficiency: Larger materials are prone to blockage in the tubular chain conveyor, hindering the normal transport of materials. Taking the actual production of a chemical plant as an example, due to material blockage, the average monthly downtime for maintenance is as long as 50 hours, resulting in a reduction of about 30% in the output of the entire production process, which seriously affects the production efficiency and economic benefits of the enterprise.

[0006] (3) Lack of targeted processing equipment: Existing material processing equipment, such as ordinary crushers, are mostly suitable for crushing general materials. They cannot efficiently process the spherical and blocky materials produced by the reaction of sulfuric acid and potassium chloride (such as possible corrosiveness, uneven hardness distribution, etc.), making it difficult to meet actual production needs.

[0007] To overcome the aforementioned problems, we have invented a dispersing device. Utility Model Content

[0008] The purpose of this invention is to solve the problems of serious equipment wear and tear, low production efficiency, lack of targeted processing equipment, and low work efficiency that prevents production from meeting needs in existing technologies. The specific solution is as follows:

[0009] A dispersing device includes a feeding mechanism, a feeding hopper, a dispersing chamber, and a discharging mechanism. The dispersing chamber is mounted on a first support, the feeding hopper is located above the dispersing chamber, the feeding mechanism is located above the feeding hopper, the feeding mechanism feeds the material to be dispersed into the feeding hopper via a feeding device, the discharging mechanism is located below the dispersing chamber, the dispersing mechanism is located inside the dispersing chamber, the dispersing mechanism is rotatably connected to a driving mechanism located outside the dispersing chamber, and the discharging mechanism is connected to a tubular chain conveying mechanism.

[0010] Furthermore, the feeding mechanism includes a horizontally arranged tube shell, a cooling sleeve inside the tube shell, and a feeding channel inside the cooling sleeve.

[0011] Furthermore, the feeding device includes an upwardly inclined tube and a vertically arranged vertical tube. The lower end of the inclined tube is connected to the end of the tube shell through a flange, the upper end of the inclined tube is connected to the upper side wall of the vertical tube, and the lower end of the vertical tube faces the feeding hopper.

[0012] Furthermore, the upper end of the vertical tube is open upwards.

[0013] Furthermore, the upper part of the feed hopper is equipped with a material height limit detector, which is electrically connected to the controller, and the lower part of the feed hopper is equipped with a chip suction device near the material inlet.

[0014] Furthermore, the dust collection device consists of three horizontal, triangularly arranged strong magnetic rods, with both ends fixed to a second support.

[0015] Furthermore, the dispersing mechanism includes three sets of roller cutter assemblies arranged in an inverted triangular pattern. Each set of roller cutters has multiple equally spaced blades and multiple spacers for separating the blades. The multiple blades and multiple spacers are staggered on the cutter roller shaft. All three sets of roller cutters have overlapping areas to form multiple dispersing cutting edges. The blades of the upper two sets of roller cutters are coarse-toothed, and the blades of the lower set of roller cutters are fine-toothed. The cutter roller shafts of the three sets of roller cutters have meshing gears at the same end and are rotatably connected to the drive mechanism.

[0016] Furthermore, the drive mechanism includes a motor and a main gear mounted on the motor spindle. The motor is fixed to the first bracket, the main gear is rotatably connected to the gear, and the motor is electrically connected to the controller.

[0017] Furthermore, the discharge mechanism includes a discharge hopper, the upper end of which is connected to the lower end of the discharge hose via a flange, the upper end of the discharge hose is connected to the dispersing chamber via a flange, the lower end of the discharge hopper is connected to the tubular chain conveying mechanism, and a venting device is provided on one side of the discharge hopper.

[0018] Furthermore, an abnormal material rejection channel is provided on one side of the feed hopper, and a manual baffle is provided at the junction of the abnormal material rejection channel and the feed hopper.

[0019] In summary, the technical solution of this utility model has the following beneficial effects:

[0020] This design incorporates a dispersing device between the cooling mechanism following the reaction of sulfuric acid and potassium chloride and the tubular chain conveyor mechanism. Above this dispersing device is a feeding device that automatically isolates the internal and external temperatures of the incoming material mechanism, prevents negative pressure, and ensures that the feeding material does not stagnate or clog. The opening at the top of the vertical pipe also facilitates cleaning and maintenance of the feeding device. An incoming material height limit detector within the dispersing device automatically detects and alerts to any material accumulation, allowing for timely removal. The feed hopper's discharge port is equipped with a chip suction device that automatically collects iron filings and impurities from the incoming material, ensuring its purity. A cooling jacket is installed within the incoming material mechanism, with circulating cooling water between the jacket and the casing to accelerate the cooling of the incoming material within the jacket, facilitating dispersing processing. The dispersing mechanism in this design employs a two-layer roller cutter assembly. The upper layer consists of two sets of roller cutters with specially designed coarse-toothed blades, which facilitates the initial entry of larger pieces of material for dispersal. The lower layer comprises a single set of roller cutters with specially designed fine-toothed blades, allowing material to continue entering the fine-toothed blades for further dispersal and reduction in size. This improves dispersing efficiency and quality while ensuring good uniformity. A flexible discharge hose connecting the discharge hopper and the dispersing chamber offers advantages such as shock resistance and flexible angle adjustment, facilitating connection between the discharge hopper and the tubular chain conveyor mechanism. A venting device on the side wall of the discharge hopper prevents negative pressure from forming within the hopper, which could hinder material flow. Attached Figure Description

Detailed Implementation

[0033] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] like Figures 1 to 9As shown, a dispersing device includes a feeding mechanism, a feeding hopper 10, a dispersing chamber 20, and a discharging mechanism. The dispersing chamber 20 is mounted on a first support 30, the feeding hopper 10 is located above the dispersing chamber 20, the feeding mechanism is located above the feeding hopper 10, and the feeding mechanism feeds the material to be dispersed 45 into the feeding hopper 10 through a feeding device 40. The discharging mechanism is located below the dispersing chamber 20, and the dispersing mechanism is installed inside the dispersing chamber 20. The dispersing mechanism is rotatably connected to a drive mechanism located outside the dispersing chamber 20, and the discharging mechanism is connected to a tubular chain conveying mechanism 50.

[0035] Specifically, the feeding mechanism includes a horizontally arranged shell 41, a cooling sleeve 42 inside the shell 41, a feeding channel 43 inside the cooling sleeve 42, and a circulating cooling water 44 between the cooling sleeve 42 and the shell 41, which can accelerate the cooling of the material (i.e. the material to be broken up 45) in the feeding channel 43 so as to break it up for processing.

[0036] Specifically, the injection device 40 includes an upwardly inclined tube 46 and a vertically arranged vertical tube 47. The lower end of the inclined tube 46 is connected to the end of the tube shell 41 through a flange 48, and the upper end of the inclined tube 46 is connected to the upper side wall of the vertical tube 47. The lower end of the vertical tube 47 faces the feed hopper 10. Preferably, the upper end of the vertical tube 47 is open upwards. This structural design of the injection device 40 has the functions of automatically isolating the internal and external temperatures of the feeding mechanism, preventing negative pressure from being generated inside the injection device 40, and ensuring that the injected material (i.e., the material to be dispersed 45) will not be retained or blocked in the injection device 40. The opening at the upper end of the vertical tube 47 also facilitates cleaning and maintenance of the injection device 40.

[0037] Specifically, the upper part of the feed hopper 10 is equipped with a material height limit detector 11, which is electrically connected to the controller 12. A chip suction device 60 is located at the lower part of the feed hopper 10 near the discharge port. The detector 11 can be an infrared sensor. Its principle is that when the material to be broken up 45 becomes clogged, it will accumulate in the feed hopper 10. When the material to be broken up 45 accumulates to a limited height, it is detected by the infrared sensor. At this time, a signal indicating that the material to be broken up 45 has exceeded the height is sent to the controller 12. The controller 12, on the one hand, suspends the conveying of the material to be broken up 45 in the feeding mechanism, and on the other hand, immediately notifies the operator to immediately handle the accumulation of the material to be broken up 45 on-site through an alarm sound. The controller 12 is a programmable logic controller, a digital arithmetic controller with a microprocessor for automated control. The controller 12 is existing technology, and its specific model and working principle will not be described in detail here. In this scheme, controller 12 is used to process the signal data of detector 11 and control the operation of various components, including controlling the conveying speed of the material to be broken up 45 in the feeding mechanism, controlling the speed of the drive mechanism, controlling the speed of the cooling water circulation pump (not shown in the figure), and controlling the sounding of the alarm (not shown in the figure). Controller 12 is installed on the outer wall of the breaking up chamber 20.

[0038] Specifically, the chip suction device 60 consists of three horizontal, triangularly arranged strong magnetic rods 61, with both ends fixed to a second support 62. The strong magnetic rods 61 are permanent magnets, and the shape of the second support 62 matches that of the feed hopper 10.

[0039] Specifically, the dispersing mechanism includes three sets of roller cutter assemblies 21 arranged in an inverted triangular pattern. Each set of roller cutters has multiple equally spaced blades 210 and multiple spacers 211 for separating the blades 210. The multiple blades 210 and multiple spacers 211 are staggered on the cutter roller shaft 212. It is particularly important to note that the orientation of the blades 210 of the three sets of roller cutters and the rotation direction of the three sets of roller cutters are subject to requirements, which should be specified in the appendix. Figure 7 As shown, the rotation direction is as indicated by the arrow. All three sets of hobs have overlapping areas (overlapping cutting edges formed on the cutting teeth of the blades 210 of the three sets of hobs) to create multiple dispersing cutting edges. The blades 210 of the upper two sets of hobs have coarse teeth 2101, and the blades 210 of the lower set of hobs have fine teeth 2102. The cutter roller shafts 212 of the three sets of hobs have meshing gears at the same end (described in detail later) and are rotatably connected to the drive mechanism. Specifically, the drive mechanism includes a motor (not shown in the figure) and a main gear 26 mounted on the motor shaft. The motor is fixed to the first bracket 30, and the main gear 26 is rotatably connected to the gears (described in detail later). The motor is electrically connected to the controller 12.

[0040] The blade 210 in this design is specially designed, and its structural parameters are all optimized. The blade 210 has an outer diameter of φ180mm, an inner diameter of φ70mm, a diameter of the circle containing the root of the cutting teeth of φ157.72mm, and a thickness of 11mm. The coarse tooth 2101 has 15 teeth and is a large arc-shaped tooth. The fine tooth 2102 has 30 teeth and is a helical tooth, comprising a short helical edge 21021, a front tooth edge 21022, and a long helical edge 21023 connected to each other. Each pair of adjacent helical teeth is connected by a chamfer of R2 (radius 2mm). The angle between the short helical edge 21021 and the radius is 10°, and the angle between the two endpoints of the front tooth 21022 and the center of the circle is 3.8°. Other parameters are shown in the attached figure. The spacer 211 has an outer diameter of φ120mm, an inner diameter of φ70mm, and a thickness of 18mm. Other parameters are shown in the attached figure.

[0041] Two bent baffles 22 are provided on both sides of the three sets of roller cutter assemblies 21 in the dispersing chamber 20.

[0042] Specifically, the discharge mechanism includes a discharge hopper 70. The upper end of the discharge hopper 70 is connected to the lower end of the discharge hose 71 via a flange (not shown in the figure). The upper end of the discharge hose 71 is connected to the dispersing chamber 20 via a flange (not shown in the figure). The lower end of the discharge hopper 70 is connected to the tubular chain conveyor mechanism 50. A venting device 72 is provided on one side of the discharge hopper 70. The venting device 72 is a venting grid, which has the function of eliminating the formation of negative pressure in the discharge hopper 70, ensuring that the dispersed material inside can flow smoothly downwards into the tubular chain conveyor mechanism 50. In addition, the condition of the dispersed material inside can be observed through the venting grid.

[0043] Specifically, an abnormal material rejection channel 13 is provided on one side of the feed hopper 10, and a manual baffle 14 is provided at the junction of the abnormal material rejection channel 13 and the feed hopper 10. When an abnormality occurs, such as the discovery that the material to be broken up contains other foreign objects or individual oversized pieces that cannot be broken up, the worker will remove them and manually open the manual baffle 14 to separate them from the abnormal material rejection channel 13 for further processing. Under normal circumstances, the manual baffle 14 is closed.

[0044] The working principle of the gear transmission between the main gear 26 and the three sets of hobs in this scheme is briefly described as follows: For ease of explanation, we divide the three sets of hobs into the first set of blades 23, the second set of blades 24, and the third set of blades 25. The first gear 27 is set on the cutter roller shaft 212 of the first set of blades 23, the second gear 28 is set on the cutter roller shaft 212 of the second set of blades 24, and the third gear 29 is set on the cutter roller shaft 212 of the third set of blades 25. The second gear 28 is a double-layered gear. The main gear 26 of the motor (rotates counterclockwise) meshes with the first gear 27 and drives the first gear 27 to rotate clockwise. The first gear 27 meshes with the lower gear of the second gear 28 and drives the second gear 28 to rotate counterclockwise. The upper gear of the second gear 28 meshes with the third gear 29 and drives the third gear 29 to rotate clockwise. The first gear 27, the second gear 28, and the third gear 29 rotate simultaneously, driving the first set of blades 23, the second set of blades 24, and the third set of blades 25 to rotate simultaneously via their respective cutter roller shafts 212. The rotation direction of all blades 210 is as follows: Figure 7 As shown by the arrow in the image.

[0045] In summary, the technical solution of this utility model has the following beneficial effects:

[0046] This design incorporates a dispersing device between the cooling mechanism following the reaction of sulfuric acid and potassium chloride and the tubular chain conveyor mechanism. Above this dispersing device is a feeding device that automatically isolates the internal and external temperatures of the incoming material mechanism, prevents negative pressure, and ensures that the feeding material does not stagnate or clog. The opening at the top of the vertical pipe also facilitates cleaning and maintenance of the feeding device. An incoming material height limit detector within the dispersing device automatically detects and alerts to any material accumulation, allowing for timely removal. The feed hopper's discharge port is equipped with a chip suction device that automatically collects iron filings and impurities from the incoming material, ensuring its purity.

A venting device on the side wall of the discharge hopper prevents negative pressure from forming within the hopper, which could hinder material flow.
