Description

Technical Field

[0001] This utility model relates to the field of pulverizers, and more particularly to a gas pulverizer. Background Technology

[0002] Traditional gas pulverizers inject materials and multiple streams of compressed air into the pulverizing chamber. At the confluence of the multiple streams of compressed air, the compressed air violently collides with the materials, pulverizing them into powder. Once the required particle size is achieved, the powder is transported by the rising airflow. Under the action of centrifugal force from the classifying wheel and the suction force from the fan, coarse and fine powders are separated.

[0003] Traditional crushers require the installation of components such as fans, making them complex and bulky, and inconvenient to move.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a gas pulverizer to solve the problems of complex structure, large size and inconvenience of movement of the pulverizer in the prior art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A gas pulverizer;

[0008] Includes a support frame; a hinge; a crushing assembly connected to the support frame via the hinge; a conveying pipe connected to a first air source and connected to the outer periphery of the crushing assembly at a preset angle; a feeding pipe connected to a material source and a second air source; a distribution plate; a filter bag connected to the distribution plate along the gas flow direction; and a receiving tank connected to the distribution plate along the powder flow direction.

[0009] The outlet of the crushing component is connected to the outer periphery of the distribution plate at a preset angle in the horizontal direction; the feeding pipe is connected to the conveying pipe; the first gas flow velocity in the conveying pipe is greater than the second gas flow velocity in the feeding pipe.

[0010] A further technical solution is that the hinge includes a base and a connecting block; the base is respectively mounted on the crushing component and the bracket; the connecting block is hinged between the bases.

[0011] A further technical solution is that the pulverizing component includes a pulverizing shell and a pulverizing body; the pulverizing body is disposed inside the pulverizing shell along the gas flow direction; a detection port is formed on the pulverizing shell, and a detection device is installed on the detection port.

[0012] A further technical solution is that the feeding pipe is connected to the feeding cylinder, and a screw is rotatably installed inside the feeding cylinder; the inlet of the feeding cylinder is connected to the material source; a power unit is installed on the support, and the power unit drives the screw to rotate.

[0013] A further technical solution is to install an electrical cabinet and an operation panel on the bracket; the output end of the operation panel is connected to the electrical cabinet; the electrical cabinet controls the first air source, the second air source, and the power device.

[0014] A further technical solution is that the feeding pipe includes pipe bodies connected in sequence; the diameter of the pipe bodies decreases sequentially.

[0015] A further technical solution is that the material distribution plate forms a cone shape near the receiving tank; the cone is connected to the receiving tank; a butterfly valve is installed between the cone and the receiving tank, and the butterfly valve opens and closes the receiving tank.

[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows: (1) The gas pulverizer conveys materials through the feeding pipe, the pulverizing component pulverizes the materials, the distribution plate and filter bag filter the powder, and the receiving tank recovers the powder; the gas pulverizer has a simple structure and the various components work together to complete the material pulverization. The gas pulverizer eliminates the blower, reduces the weight, and is easy to move.

[0017] (2) The conveying pipe is connected to the outer periphery of the crushing component at a preset angle. The conveying pipe is set in the front-to-back direction and tilted to the lower left corner at a certain angle to connect to the outer periphery of the right side of the crushing component. The first gas and the second gas merge in the conveying pipe to form gas. The gas enters the crushing component to form an annular flow path. During the process, the gas drives the material to be repeatedly crushed to form powder. The annular flow path of the gas fills the crushing component, avoiding the formation of crushing dead corners in the crushing component. The outlet of the crushing component is connected to the outer periphery of the distribution plate at a preset angle in the horizontal direction. The outlet of the crushing component is located in the middle position on the right side of the crushing component. The outlet of the crushing component and the outer periphery of the distribution plate form an acute angle, so that the gas and powder form an annular flow path when entering the distribution plate.

[0018] (3) The gas and material in the crushing component flow rapidly in a circular path, and the crushing component bears a large inertia; the crushing component and the support are not rigidly connected, and the crushing component is connected to the support through a hinge; the connecting block and the seat can move; when the gas and material flow in a circular path, the material acts on the crushing body, and the material is repeatedly crushed to form fine powder.

[0019] (4) The cone gradually narrows from top to bottom, and the powder quickly accumulates at the bottom of the cone. The gas cannot blow up the accumulated powder because of the large amount of powder accumulation. The collection tank collects the powder quickly, and the replacement of the collection tank will not affect the operation of the gas pulverizer, thus improving the working efficiency.

[0023] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0024] Figure 1 A three-dimensional structural schematic diagram of the gas pulverizer according to an embodiment of the present invention is shown. Figure 2 A side view of the gas pulverizer according to an embodiment of the present invention is shown. (In conjunction with...) Figures 1-2 As shown, this utility model discloses a gas pulverizer including a feeding pipe 5, a support 1, a hinge 2 mounted on the support 1, a pulverizing component 3 vertically connected to the support 1 via the hinge 2, a conveying pipe 4 connected to a first gas source, a distributing plate 6 mounted on the support 1, a filter bag 7 connected to the distributing plate 6 along the gas flow direction, and a receiving tank 8 connected to the distributing plate 6 along the powder flow direction.

[0025] Feed pipe 5 connects to the material source and the second gas source. The second gas carries the material from top to bottom along feed pipe 5 into conveying pipe 4. The second gas flows in one direction only to prevent the first gas in conveying pipe 4 from entering feed pipe 5, thus preventing material backflow. Feed pipe 5 is connected to conveying pipe 4. Feed pipe 5 is arranged vertically and its lower end is connected to conveying pipe 4.

[0026] The feeding pipe 5 conveys materials, the crushing component 3 crushes materials, the distributing disc 6 and filter bag 7 filter powder, and the receiving tank 8 recovers powder. The gas pulverizer has a simple structure; through the coordinated operation of its various components, it can complete the crushing of materials. The gas pulverizer eliminates the need for a blower, reducing weight and facilitating movement.

[0027] The feed pipe 4 connects to the outer periphery of the crushing component 3 at a preset angle. The feed pipe 4 is set in the front-to-back direction and tilted to the lower left corner at a certain angle to connect to the outer periphery of the right side of the crushing component 3. The first gas and the second gas merge in the feed pipe 4 to form a gas. The gas enters the crushing component 3 and forms an annular flow path. During the flow, the gas carries the material and repeatedly crushes it into powder. The annular flow path of the gas fills the crushing component 3, avoiding the formation of crushing dead corners.

[0028] The outlet of the crushing component 3 connects to the outer periphery of the distribution plate 6 at a preset angle in the horizontal direction. The outlet of the crushing component 3 is located in the middle of the right side of the crushing component 3. The outlet of the crushing component 3 and the outer periphery of the distribution plate 6 form an acute angle, and the gas and powder enter the distribution plate 6 to form an annular flow path. The outlet of the crushing component 3 and the outer periphery of the distribution plate 6 are at the same horizontal height, and the gas and powder quickly enter the distribution plate 6, forming a fast-flowing annular path in the distribution plate 6.

[0029] The upper end of the distribution plate 6 is connected to the filter bag 7, which filters the powder mixed with the gas. After the gas pulverizer stops working, the powder in the filter bag 7 falls and accumulates, and enters the collection tank 8 for recycling.

[0030] Hinge 2 includes a base 21 and a connecting block 22. The base 21 is mounted on the crushing assembly 3 and the support 1. The connecting block 22 is hinged to each base 21 at both ends. Gas and material flow rapidly in an annular manner inside the crushing assembly 3, and the crushing assembly 3 bears a relatively large inertia. To avoid a rigid connection between the crushing assembly 3 and the support 1, the crushing assembly 3 is connected to the support 1 via hinge 2, and the connecting block 22 and the base 21 can move between each other.

[0031] The crushing component 3 includes a crushing shell 31 and a crushing body 32. The crushing body 32 can be annular. The crushing body 32 is disposed inside the crushing shell 31 along the gas flow direction. Gas and material flow together, and the material acts on the crushing body 32, repeatedly crushing the material to form fine powder.

[0032] The crushing shell 31 forms a detection port 33, and a detection device is installed in the detection port 33. The detection device can be a pressure sensor to detect the pressure of the crushing shell 31 in real time.

[0033] The flow velocity of the first gas in the conveying pipe 4 is greater than the flow velocity of the second gas in the feeding pipe 5. The second gas conveys the material while preventing the first gas from flowing into the feeding pipe 5. The first gas carries the material in the crushing shell 31, which acts on the crushing body 32, and drives the powder to flow in a ring in the distribution plate 6.

[0034] The upper end of the feeding pipe 5 is connected to the rear end of the feeding cylinder 51, and a screw 52 is rotatably installed inside the feeding cylinder 51. A material hood is formed at the inlet of the feeding cylinder 51 to store the material. A power device 53 that drives the screw 52 to rotate is installed on the bracket 1. The screw 52 drives the material along the feeding cylinder 51 into the feeding pipe 5, and the power of the power device 53 is controlled to complete the quantitative conveying of the material in the feeding pipe 5.

[0035] The feeding pipe 5 includes pipe bodies 54 connected sequentially from top to bottom. Each pipe body 54 is sequentially connected to a feeding cylinder 51, a second gas source, a diameter that decreases, a diameter that decreases again, and then connected to a conveying pipe 4. The pipe body 54 first completes the collection of material and the second gas, and then the diameter of the pipe body 54 gradually decreases, increasing the flow rate of material and the second gas, allowing them to quickly enter the conveying pipe 4, thus preventing the first gas from flowing into the feeding pipe 5 and preventing material backflow.

[0036] The distribution plate 6 forms a cone 61 near the receiving tank 8. The diameter of the cone 61 gradually decreases, and the powder quickly accumulates at the lower end of the cone 61. When a large amount of powder accumulates, the gas cannot blow it away.

[0037] A butterfly valve 81 is installed between the cone 61 and the receiving tank 8 to open and close the receiving tank 8. When the gas pulverizer stops working, the butterfly valve 81 opens the receiving tank 8, and the powder accumulated in the cone 61 falls into the receiving tank 8 for recycling. When the butterfly valve 81 closes the receiving tank 8, the gas pulverizer restarts, and the receiving tank 8 is replaced. The receiving tank 8 collects powder quickly without affecting the operation of the gas pulverizer, thus improving work efficiency.

[0038] The bracket 1 houses the electrical cabinet 11 and the control panel 12. The output of the control panel 12 is connected to the electrical cabinet 11. The electrical cabinet 11 controls the first gas source, the second gas source, and the power unit 53. Electric valves are installed at both the first and second gas sources for opening and closing, controlling the delivery of the first and second gases. The electrical cabinet 11 controls the power unit 53 to quantitatively deliver materials.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
