Description

Technical Field

[0001] This utility model relates to the technical field of bentonite processing equipment, specifically to a sodium-based machine for processing low-dust bentonite. Background Technology

[0002] Bentonite, as an important clay mineral material, has wide applications in many fields. The sodium calcination process of bentonite is a key means to improve its performance. Currently, the commonly used process involves mixing bentonite and soda ash, then processing them using a roller crusher to ensure uniform mixing, followed by stacking and drying. However, traditional sodium calcination machines have significant drawbacks in performing this core crushing process. The crushing process generates a large amount of dust, which disperses freely, severely polluting the working environment. This not only harms the health of operators but also negatively impacts the normal operation and maintenance of other equipment, and may even lead to fluctuations in product quality. Furthermore, the uniformity and efficiency of mixing in the raw material mixing stage of traditional sodium calcination machines need improvement. Therefore, there is an urgent need to develop a low-dust, high-efficiency sodium calcination machine for bentonite processing to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a sodium-based machine for processing low-dust bentonite, comprising a frame and an extrusion chamber fixedly disposed on the upper end of the frame. A double-roller extrusion crusher is provided inside the extrusion chamber. A premixing chamber is connected to the upper end of the extrusion chamber. A stirring mechanism is provided inside the premixing chamber. A bentonite inlet and an alkali inlet are provided at the upper end of the premixing chamber. A circular atomizing nozzle is fixedly disposed on the top surface inside the premixing chamber. A water pump is connected to the circular atomizing nozzle through a pipe. Dust collection hoods are fixedly disposed on both the left and right sides inside the extrusion chamber. A bag filter is connected to the dust collection hoods through a dust suction pipe. A spiral discharge mechanism is fixedly disposed at the bottom outlet of the extrusion chamber.

[0007] Furthermore, the double-roll crusher includes two crushing rolls rotatably disposed inside the crushing chamber, and also includes a motor fixedly disposed outside the crushing chamber for driving the crushing rolls.

[0010] Furthermore, the spiral discharge mechanism includes a conveying cylinder, an auger, and a drive motor assembled in sequence.

[0011] (III) Technical Effects

[0012] The advantages of this utility model compared with the prior art are:

[0013] 1. Significant Dust Reduction: Dust collection hoods are installed on both sides inside the extrusion chamber, connected to a bag filter via a suction pipe. This effectively collects dust generated during the extrusion and crushing process, significantly reducing dust levels in the workshop and greatly improving the working environment. The annular atomizing nozzles fixed to the top surface of the premixing chamber atomize water supplied by a water pump, appropriately increasing material humidity and suppressing dust generation to some extent, while also promoting better mixing and reaction of the materials.

[0014] 2. Uniform mixing: The premix chamber is equipped with a stirring mechanism. The stirring motor drives the stirring shaft and multiple stirring arms to rotate, which can fully mix the bentonite and alkali, improve the uniformity and efficiency of mixing, provide better conditions for the subsequent sodiumization reaction, and improve the stability of product quality.

[0026] In this embodiment, as a preferred technical solution, the double-roll crusher 3 includes two crushing rollers 12 rotatably disposed inside the crushing chamber 2, and also includes a motor 13 fixedly disposed outside the crushing chamber 2 for driving the crushing rollers 12.

[0027] In this embodiment, as a preferred technical solution, the stirring mechanism includes a stirring motor 14 fixedly mounted on the upper end of the premix chamber 4, and a stirring shaft 15 fixedly mounted on one end of the drive shaft of the stirring motor 14 that extends into the interior of the premix chamber 4.

[0028] In this embodiment, as a preferred technical solution, the spiral discharge mechanism 11 includes a conveying cylinder 18, an auger 19, and a drive motor 20 assembled in sequence.

[0029] The working principle of this utility model is as follows: This low-dust bentonite processing sodium calciner uses a stirring mechanism in the premix chamber 4 to initially mix and humidify bentonite and alkali, reducing dust generation during subsequent processing; the mixture is further crushed by a roller extrusion crusher 3 to make it more uniform and refined; the dust generated during the extrusion process is collected by a dust collection hood 9 and a bag filter 10 to achieve low-dust processing; finally, the processed material is output by a screw discharge mechanism 11.

[0030] The working process of this utility model is as follows:

[0031] 1. Raw material preparation and premixing: Bentonite is added to the premixing chamber 4 through the bentonite inlet 5 and alkali through the alkali inlet 6. The stirring motor 14 is started, and its drive shaft drives the stirring shaft 15 to rotate. The stirring arms 16 on the stirring shaft 15 stir and mix the bentonite and alkali. At the same time, the water pump 8 is started, and water enters the annular atomizing nozzle 7 through the pipeline to atomize and humidify the materials in the premixing chamber, assisting in mixing and suppressing dust generation.

[0032] 2. Material enters the extrusion chamber: After the mixed and humidified material reaches a certain amount or after a certain mixing time, the electrically controlled gate valve 17 at the bottom outlet of the premix chamber 4 is opened, and the material falls into the extrusion chamber 2 below.

[0033] 3. Crushing and Dust Collection: The motor 13 is started, driving the compression rollers 12 to rotate. The two compression rollers 12 crush the material entering the compression chamber 2, making it more uniform and finer. Dust generated during the crushing process is collected by dust collection hoods 9 fixedly installed on the left and right sides inside the compression chamber 2. The dust enters the bag filter 10 through the suction pipe 21, and the purified air is discharged. The dust is collected and treated. An air inlet valve 22 is located at the rear of the compression chamber 2.

[0034] 4. Discharge: The material after extrusion and crushing falls from the bottom outlet of the extrusion chamber 2 and enters the screw discharge mechanism 11. The drive motor 20 drives the auger 19 to rotate inside the conveying cylinder 18, conveying the material out for subsequent sodium treatment.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto.
