Description

Technical Field

[0001] This utility model belongs to the field of ultrafine material pulverization technology, specifically relating to a deep processing device for flaky inorganic powder. Background Technology

[0002] In the cosmetics and industrial sectors, finely sized flaky inorganic powders, such as mica, synthetic mica, silica, and glass powder, are required. Therefore, the flaky substrate needs to be pulverized. Existing pulverization technologies typically utilize multi-stage pulverization with a pulverizer. However, ultrafine powders, due to their large surface area and high surface energy, are prone to agglomeration, and electrostatic effects can exacerbate this phenomenon, resulting in uneven crushing. Furthermore, existing equipment often experiences material adhesion to the inner wall of the grinding device during the grinding process, leading to material loss, reduced grinding efficiency, or significant metering errors. Further improvements are necessary. Utility Model Content

[0003] The purpose of this invention is to provide a deep processing device for flake-shaped inorganic powders to solve the problems of material loss, reduced grinding efficiency, or large measurement errors caused by material adhesion during the grinding process in the prior art.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A deep processing device for flake-shaped inorganic powder includes a processing vessel, a top cover, a grinding assembly, and a pulverizing assembly. The grinding assembly and the pulverizing assembly are vertically arranged sequentially inside the processing vessel. The top cover is installed on the top of the processing vessel, and a driving component is mounted on the top cover. The driving component is pulverically connected to the grinding assembly and the pulverizing assembly. The processing vessel has a sloping bottom, which is connected to a circulation shell via a circulation pipe. The circulation shell is located at the bottom of the processing vessel.

The pulverizing assembly includes at least a pulverizing tube rotatably connected to the top end of the connecting pipe. The outer surface of the pulverizing tube is provided with pulverizing rollers and spray holes. The inner wall of the processing vessel is also provided with pulverizing rollers that intersect with the pulverizing rollers on the pulverizing tube. A circulation pump is provided inside the circulation shell. The inlet of the circulation pump is connected to the inner cavity of the circulation shell, and the outlet of the circulation pump is connected to the bottom end of the connecting pipe.

[0006] In this application, after the drive unit is activated, the raw material is added to the processing vessel and falls into the grinding assembly. The drive unit drives the grinding assembly to grind the material, and the ground material is discharged to the bottom of the processing vessel. At the same time, the drive unit can drive the crushing assembly to mix the materials. After a certain period of time, the circulation pipeline is connected, which can extract the material from different positions on the sloping bottom of the processing vessel and transport it to the connecting pipe through the circulation pump, the inner cavity of the circulation shell, and the crushing pipe. The material is then sprayed out from the middle of the processing vessel through the crushing pipe and the spray hole. In this way, the added material is first ground to avoid the material from clumping and affecting the grinding and crushing effect. Then, the material in different positions in the processing vessel is circulated, which improves the uniformity of crushing and ensures that the processed flaky inorganic powder has high particle size uniformity, thus improving the grinding effect.

[0007] Furthermore, the crushing assembly also includes a rotating sleeve installed at the bottom end of the crushing tube, the rotating sleeve being connected to a flipping rod in its radial direction, and a plurality of flipping plates being installed on the flipping rod at a staggered position; a rotating wheel is installed at the end of the flipping rod, and the rotating wheel abuts against the inclined bottom.

[0008] The rotation of the tilting rod and the tilting plate further improves the crushing effect of materials in the processing vessel.

[0009] Furthermore, the sloping bottom is provided with circulation holes arranged in a circular array, and the circulation pipeline includes an output branch pipe connected to the circulation holes, an output main pipe connected to the end of the output branch pipe, and a control valve installed on the output main pipe; the output main pipe is connected to the circulation chamber provided in the circulation housing.

[0010] Furthermore, the inlet of the circulating pump is connected to a circulating input pipe, which is connected to the circulating chamber, and the outlet of the circulating pump is connected to a bottom pipe, which is connected to the connecting pipe.

[0011] Furthermore, the driving component includes a grinding motor mounted on the top cover, the output end of the grinding motor being connected to an output shaft that extends into the processing vessel.

[0012] Furthermore, the grinding assembly includes an integrated housing, a grinding groove installed inside the integrated housing, a grinding head that mates with the grinding groove mounted on the output shaft, and a material discharge port at the bottom of the grinding groove.

[0013] Furthermore, a venting rod is provided through the integrated shell, and a gas interface connected to the top of the venting rod is provided at the top of the integrated shell; an outlet ring pipe connected to the bottom of the venting rod is provided at the bottom of the integrated shell; and outlet holes are arranged in a circumferential array on the inner surface of the outlet ring pipe.

[0014] The ventilator is used to disperse the ground material, allowing it to fall flexibly to different locations in the processing vessel for further crushing.

[0015] Furthermore, the top cover is provided with a feed inlet and an expansion interface, a transition cylinder is connected between the sloping bottom and the circulation shell, a discharge port is provided at the top of the transition cylinder, a discharge port is provided on the side wall of the transition cylinder, and a discharge pipe is connected between the discharge port and the discharge port to form the discharge channel; the circulation pipeline is also connected to the feed inlet.

[0016] The utility model adopting the above technical solution has the following advantages:

[0017] In this application, the grinding components can pre-grind the added material (i.e., flaky inorganic powder) to improve the subsequent pulverization effect; the driving components can drive the grinding and pulverizing components to rotate, resulting in high power utilization; the air outlet ring pipe can distribute and blow the ground material to prevent it from concentrating too much during falling, thus improving the subsequent pulverization effect; through the cooperation of the circulation pump, the inner cavity of the circulation shell, the pulverizing pipe and its spray holes, the material at the bottom or even the bottom edge of the processing vessel is transported to the middle of the processing vessel and sprayed out; in this way, the material at different positions in the processing vessel is exchanged and circulated for pulverization, improving the uniformity of pulverization, and the gas can be transported through the circulation pipeline to clean the processing vessel, prevent material adhesion, and make it highly practical.

Detailed Implementation

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0030] like Figures 1 to 8As shown in the figure, a deep processing device for flake-shaped inorganic powder according to an embodiment of the present invention includes a processing vessel 100, a top cover 200, a grinding component 300, and a crushing component. The grinding component 300 and the crushing component are vertically arranged sequentially inside the processing vessel 100. The top cover 200 is installed on the top of the processing vessel 100 and can be locked and fixed by fastening screws 204 or buckles. A driving component is installed on the top cover 200, including a grinding motor 202 installed on the top cover 200. The output end of the grinding motor 202 is connected to an output shaft 310, which extends into the processing vessel 100 and is connected to the grinding component 300 and the crushing component for transmission. A feed inlet 201 is provided on the top cover 200 for feeding. The processing vessel 100 is provided with a sloping bottom 107, which is connected to a circulation shell 103 through a circulation pipe. The ring shell 103 is located at the bottom of the processing vessel 100; a connecting pipe 122 is centrally located at the bottom of the processing vessel 100, and a discharge channel is provided between the connecting pipe 122 and the inclined bottom 107; the crushing assembly includes a crushing tube 109 rotatably connected to the top of the connecting pipe 122, and a crushing roller 110 and a spray hole 111 are provided on the outer surface of the crushing tube 109. The inner wall of the processing vessel 100 is also provided with crushing rollers 110 that are staggered with the crushing rollers on the crushing tube 109; the crushing rollers 110 on the processing vessel 100 and the crushing tube 109 are staggered. During processing: the spray hole 111 is drilled first, and then the crushing roller 110 is welded to the outer surface of the crushing tube 109; an mounting plate 120 is installed on the inner wall of the processing vessel 100, and the crushing roller 110 is welded to the mounting plate 120. The staggered crushing rollers 110 achieve the crushing of materials. A circulation pump is installed inside the circulation housing 103. The inlet of the circulation pump is connected to the inner cavity of the circulation housing 103, and the outlet of the circulation pump is connected to the bottom end of the connecting pipe 122.

[0031] In this embodiment, the grinding motor 202 is started, and the material is added to the processing vessel 100, specifically falling into the grinding tank 304 of the grinding assembly 300. The grinding motor 202 drives the grinding assembly 300 to grind the material, and the ground material is discharged to the bottom of the processing vessel 100. At the same time, the grinding motor 202 can drive the crushing assembly to crush the material. The crushing continues for a certain period of time. After that, the circulation pipeline is connected, and the material at different positions on the inclined bottom 107 of the processing vessel 100 can be extracted and transported through the circulation pump, the inner cavity of the circulation shell 103, and the crushing pipe 109. The material is fed to the connecting pipe 122 and sprayed out through the crushing pipe 109 and the spray hole 111 into the middle of the processing vessel 100. In this way, the added material is first ground to prevent the material from clumping, and then crushed to improve the processing effect of deep processing. Then the material in different positions in the processing vessel 100 is circulated to improve the particle size uniformity of the processed particles. In addition, after the material is discharged, the operation of the circulation pipeline is controlled to circulate and transport gas in the processing vessel 100. The gas can blow off the sticky material, reduce the amount of material sticking, clean the processing vessel 100, and make it highly practical.

[0032] For example, a support plate extends from the bottom of the processing vessel 100 and is connected to the circulation shell 103; and a notch 102 is formed between the support plates to allow for the installation, inspection and maintenance of the circulation pipeline.

[0033] For example, the processing vessel 100, the support plate, and the circulation shell 103 are connected by welding.

[0034] A bottom cover 106 is detachably installed at the bottom of the circulation housing 103; both the top cover 200 and the bottom cover 106 can be installed and fastened by fastening screws 204.

[0035] For example, such as Figure 6 , Figure 7 As shown, the grinding assembly 300 in this embodiment includes an integrated shell 303, a grinding groove 304 installed in the integrated shell 303, a grinding head 309 that cooperates with the grinding groove 304 installed on the output shaft 310, and a material discharge port 311 opened at the bottom of the grinding groove 304.

[0036] The grinding head 309 is mounted on the output shaft 310 and is connected to the output shaft 310 by a keyway to transmit power; the bottom of the output shaft 310 passes through the grinding groove 304 and is connected to the top of the crushing tube 109 so that power can be transmitted to the crushing tube 109 at the same time.

[0037] For example, the grinding groove 304 is arc-shaped, the grinding surface shape of the grinding head 309 corresponds to that of the grinding groove 304, and the grinding surface shape of the grinding head 309 and the surface of the grinding groove 304 are provided with grinding protrusions.

[0038] The gap between the grinding head 309 and the grinding tank 304 gradually decreases from the top to the bottom center of the grinding tank 304 to facilitate fine grinding of the material. In fact, the grinding head 309 and the grinding tank 304 can also grind some particles to obtain powder with a particle size that meets the specified requirements.

[0039] For example, three integrated shells 303 are spaced apart and connected by a connecting ring at the top and a connecting pipe in the middle; a threaded hole is machined on the connecting ring, and an adjusting screw 302 is connected in the threaded hole. The gap between the grinding head 309 and the grinding groove 304 can be adjusted by adjusting the adjusting screw 302.

[0040] For example, an expansion interface is provided on the top cover 200, which can be used as a passage for the additive interface or gas interface 301; or, an additional expansion interface is provided as a detection interface 203; the detection interface 203 is used to install temperature sensors, air pressure sensors and humidity sensors, etc.

[0041] A transition cylinder is connected between the inclined bottom 107 and the circulation shell 103. The top of the transition cylinder is provided with a feed port 117, and the side wall of the transition cylinder is provided with a discharge port 108. A discharge pipe is connected between the feed port 117 and the discharge port 108 to form a discharge channel. In this way, the material is fed through the feed port 201, and after grinding by the grinding head 309 and the grinding tank 304, it enters the crushing process. After being crushed evenly, it falls from the feed port 117 and is output through the discharge pipe and the discharge port 108.

[0042] In this embodiment, as Figure 8 As shown, the crushing assembly also includes a rotating sleeve installed at the bottom of the crushing tube 109. A tilting rod 118 is connected to the rotating sleeve in the radial direction, and several tilting plates 121 are installed on the tilting rod 118 at a staggered position. A rotating wheel 119 is installed at the end of the tilting rod 118, and the rotating wheel 119 abuts against the inclined bottom 107. The crushing tube 109 is fixedly connected to the rotating sleeve, and the rotating sleeve and the tilting rod 118 can be rotatably connected by bearings. When the crushing tube 109 rotates, it drives the tilting rod 118 to rotate. At the same time, under the action of friction between the rotating wheel 119 and the inclined bottom 107, the tilting rod 118 rotates. The rotation of the tilting rod 118 and the tilting plates 121 further improves the crushing effect of the material in the processing vessel 100.

[0043] For example, the size of the flip plate 121 gradually decreases from the center end of the flip rod 118 near the crushing tube 109 to the end, so as to fit the sloping bottom 107.

[0044] For example, there are two symmetrically arranged flip rods 118; the flip plates 121 on the flip rods 118 are installed in a staggered manner; in fact, the flip rods 118 and the flip plates 121 can be installed by welding.

[0045] For example, a gap 113 is left between the mounting plate 120 and the outer edge of the inclined bottom 107, and the rotating wheel 119 can move within the gap 113; in fact, a friction plate can be installed at the bottom of the mounting plate 120 to form a coupling wall 112 and couple it with the rotating wheel 119; thus realizing the friction drive of the rotating wheel 119.

[0046] In this embodiment, as Figure 5 As shown, the sloping bottom 107 has a circular array of circulation holes 114. The circulation pipeline includes an output branch pipe 101 connected to the circulation holes 114, an output main pipe connected to the end of the output branch pipe 101, and a control valve 104 installed on the output main pipe. The output main pipe is connected to the circulation chamber 116 provided in the circulation housing 103.

[0047] For example, the circulation chamber 116 is formed by sealing the outer interlayer of the circulation housing 103 with a bottom cover 106; the inlet of the circulation pump is connected to a circulation input pipe, which connects to the circulation chamber 116, and the outlet of the circulation pump is connected to a bottom pipe 105, which connects to a connecting pipe 122. The inner interlayer of the circulation housing 103 serves as the space for installing the bottom pipe 105. Circulation holes 114 are opened at different heights on the sloping bottom 107, and some circulation holes 114 are connected to the main output pipe via an output bend 115 and a tee pipe, thus allowing material (powder after grinding the substrate) at different heights to be extracted. In practice, the control valve 104 can be a solenoid valve connected to a PLC controller for automatic control.

[0048] In this embodiment, as Figure 6 , Figure 7 As shown, a venting rod 308 is provided on the integrated shell 303, and a gas interface 301 connected to the top of the venting rod 308 is provided on the top of the integrated shell 303; an exhaust ring pipe 306 connected to the bottom of the venting rod 308 is provided on the bottom of the integrated shell 303; and exhaust holes 307 are arranged in a circular array on the inner surface of the exhaust ring pipe 306.

[0049] For example, if there are three integrated shells 303, the circumferentially arranged integrated shells 303 form three gaps, in which support rods 305, ventilation rods 308, etc. can be installed without affecting the function of the integrated shells 303. Through the ventilation rods 308, the ground material is dispersedly purged, so that the material can flexibly fall to different positions in the processing vessel 100 for crushing.

[0050] In fact, two integrated shells 303 can be set as needed, with the two integrated shells 303 arranged alternately. Of course, four or six integrated shells 303 can also be set as needed. In this way, different grinding powders can be placed in different integrated shells 303 and added as needed, which is highly flexible and practical.

[0051] In this embodiment, when the deep processing device for flaky inorganic powder is running, the grinding motor 202 is powered on and started. Material (which may contain particles) is added into the processing vessel 100 through the feed inlet 201. The grinding motor 202 drives the output shaft 310 to rotate, and the grinding head 309 grinds the material in the grinding tank 304. A gap for material leakage is left between the discharge port 311 and the output shaft 310. The ground material leaks down from the discharge port 311. The air outlet ring pipe 306 can be vented, and the gas is blown evenly through the air outlet 307 to make it more evenly processed by the subsequent crushing process. Then, the material is mixed in multiple directions by the crushing roller 110 and the tilting plate 121. After a certain period of mixing and grinding, if the particle size meets the requirements, it is directly discharged; otherwise, the circulation pipeline is connected, and materials at different positions at the bottom of the processing vessel 100 are extracted and transported to the middle of the processing vessel 100 for further processing via the circulation pump, circulation shell 103, connecting pipe 122, grinding pipe 109, and spray hole 111. Generally, two to three cycles of cyclic grinding are sufficient to obtain materials with uniform particle size that meet the requirements. In this way, the material at different positions within the processing vessel 100 is rotated and cyclically ground, improving the uniformity of grinding and ensuring the uniformity of particle size of the processed flaky inorganic powder.

[0052] For example, the circulation pipeline is also connected to the feed inlet, into which the crushed raw materials are input for further grinding, thereby improving the fineness of the deep processing of the raw materials and ensuring that the materials reach the required particle size.

[0053] For example, a dustproof connection line is provided in the circulation chamber 116, which is connected to a power source outside the circulation pump and processing vessel 100 to supply power to the circulation pump. For example, the circulation pump can be an air pump driven by a pneumatic motor to pump materials.

[0054] This embodiment provides a deep processing device for flake-shaped inorganic powder. Material is added to the processing vessel 100 through the feed inlet 201. A driving component drives the grinding head 309 to grind the material, and the crushing tube 109 to crush it. Thus, the grinding assembly 300 pre-grinds the added material, improving the subsequent crushing effect. The driving component rotates the grinding assembly 300 and the crushing assembly, resulting in high power utilization. The air outlet ring pipe 306 provides distributed blowing of the ground material, preventing excessive concentration during descent and improving the subsequent crushing effect. Through the cooperation of the circulating pump, the inner cavity of the circulating housing 103, the crushing tube 109, and its ejection holes 111, material from the bottom or even the bottom edge of the processing vessel 100 is transported to the center of the processing vessel 100 and ejected. This process repositions and circulates the material at different locations within the processing vessel 100, improving the uniformity of crushing. Simultaneously, the circulating material processing prevents material adhesion, making it highly practical.

[0055] The above provides a detailed description of a deep processing device for flake-shaped inorganic powders provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
