Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of bentonite mixers, specifically to a bentonite mixer capable of quantitative feeding. Background Technology

[0002] In the field of bentonite deep processing, mixing is a core process for preparing bentonite slurries, composite bentonite, and other products. It requires uniformly mixing bentonite raw materials with water and additives in a specific ratio. The accuracy of this mixing ratio directly determines key indicators such as the product's adsorption performance and dispersibility. For example, when preparing bentonite drilling mud, if the ratio error between bentonite and water exceeds 5%, the mud viscosity will not meet construction requirements, affecting drilling efficiency and safety. However, currently available bentonite mixing equipment generally suffers from the significant drawback of not being able to automatically control the amount of material fed each time, requiring manual weighing and calculation. This severely restricts the stability of mixing quality and production efficiency. Traditional bentonite mixing equipment relies entirely on manual operation for feeding: operators must first weigh the bentonite raw material using a platform scale and then manually pour it into the mixing tank. This method is not only time-consuming and labor-intensive, making it unsuitable for mass production needs, but manual operation is also prone to inaccurate feeding ratios due to weighing errors (such as material spillage or reading deviations) and miscalculations in proportioning, leading to fluctuations in the performance of the mixed product. For example, if a batch of product has insufficient bentonite feed, it may have insufficient adsorption capacity, requiring re-mixing and increasing production costs. Therefore, the development of bentonite mixers with automatic quantitative feeding functions and no need for manual calculation of feed amount has become an urgent need for the industry to improve mixing quality and production efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a bentonite mixer with quantitative feeding capability, which solves the technical problem in the prior art that manual operation is prone to inaccurate feeding ratio due to weighing errors and miscalculation of proportions, which in turn causes fluctuations in the performance of the product after mixing.

[0015] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] like Figures 1-4 As shown, it illustrates a bentonite mixer capable of quantitative feeding according to an embodiment of the present disclosure, comprising: The outer casing and the outer frame, wherein the outer frame is fixed to the side surface of the outer casing; A feeding assembly, which is mounted on the outer frame; A stirring assembly, wherein the stirring assembly is disposed inside the housing; The feeding assembly includes a feeding box, which is fixed to the bottom of the outer frame. The feeding box is located on the top of the outer frame. A conveyor auger connects the feeding box and the feeding box. A conveyor belt is installed inside the outer frame. The outer frame and the conveyor belt are higher than the top of the outer shell. Several pushing protrusions are provided on the surface of the conveyor belt. Notches are opened at both ends of the bottom of the feeding box. The height of the notches matches the height of the pushing protrusions. A leveling cover is provided on the side surface of the feeding box. The inner surface of the leveling cover slides against the upper surface of the pushing protrusion.

[0022] In some examples, in order to achieve precise quantitative feeding of bentonite, avoid fluctuations in the feed amount from affecting the uniformity of mixing, and adapt to the material ratio requirements of different batch mixing operations, a feeding component was designed. This component includes a feeding box at the bottom of the outer frame as the initial storage structure, which can temporarily store the bentonite to be mixed. Its top is connected to the feeding box at the top of the outer frame through a conveying auger. The conveying auger is driven by electricity to rotate, which can stably transport the bentonite in the feeding box to the feeding box, providing a continuous material supply for subsequent quantitative feeding, while avoiding the bentonite from clumping and clogging during the transportation process.

[0023] The conveyor belt inside the outer frame is set horizontally and its overall height is higher than the top of the outer shell, ensuring that the material on the conveyor belt can fall smoothly into the outer shell; several pushing protrusions on the surface of the conveyor belt are evenly distributed along the length of the conveyor belt, and independent material receiving areas are formed between adjacent protrusions. By controlling the running speed of the conveyor belt and the running time of a single run, the amount of material in each receiving area can be precisely controlled, thereby realizing quantitative control of the amount of material fed each time.

[0024] The notches at both ends of the bottom of the feed box are matched with the height of the pusher protrusions. When the conveyor belt drives the pusher protrusions to move to the bottom of the feed box, the protrusions can pass through the notches and enter the feed box, scraping the bentonite in the feed box into the receiving area of ​​the adjacent protrusions, thus preventing the material from accumulating at the bottom of the feed box.

[0025] The scraper cover on the side surface of the feed box is flat, and its inner surface slides against the upper surface of the pusher protrusion. When the pusher protrusion carries the material out of the feed box, the scraper cover can scrape off the excess bentonite on the upper surface of the protrusion back into the feed box, ensuring that the amount of material in each containment area is consistent and further calibrating the accuracy of the feed amount.

[0026] During operation, the conveying auger transports bentonite from the feeding hopper to the feed hopper; the conveyor belt starts, driving the pushing protrusions to move, which pass through the notch to receive the material, while the leveling cover scrapes off excess material; the conveyor belt continues to run, conveying a fixed amount of material to the top of the outer shell and allowing it to fall into the shell. The conveying auger ensures material supply, the pushing protrusions achieve quantitative segmentation, and the leveling cover calibrates accuracy; all components work together to achieve precise quantitative feeding, laying the foundation for uniform mixing.

[0027] like Figures 1-4As shown in the figure, this embodiment proposes that the stirring assembly includes a pair of stirring shafts, both of which are electrically driven and rotatably connected inside the outer shell. Several stirring frames are provided on the surface of each stirring shaft. A side frame is provided on one side surface of the outer shell, and a guide frame is provided on the other side surface of the outer shell. A top cover is slidably fitted onto the guide frame, and the bottom surface of the top cover is slidably fitted against the upper surface of the outer shell. The other end of the top cover is connected to the side frame via a horizontal linear drive. A bottom cover is provided at the bottom of the outer shell, communicating with the interior of the outer shell. A discharge auger is provided inside the bottom cover, and a discharge pipe is provided on one side of the bottom cover. One end of the discharge auger extends into the discharge pipe. A dust collection hood is provided on the top of the top cover, and a suction pipe is provided on the top of the dust collection hood.

[0028] In some examples, in order to achieve uniform mixing and efficient transportation of bentonite, while avoiding dust dispersion during the mixing process and ensuring a clean working environment.

[0029] Inside the outer shell, a pair of stirring shafts are horizontally connected by bearings and are distributed in parallel. Both shafts are driven by electricity to rotate synchronously in opposite directions, ensuring that the material can fully convect between the two shafts during stirring. Several stirring racks on the surface of the stirring shafts are arranged in a spiral or staggered pattern, which can gather the bentonite inside the outer shell from both sides to the center. Then, the rotational force is used to disperse and mix the material, avoiding the formation of dead zones in the stirring process and ensuring that the bentonite is stirred evenly. This design is suitable for stirring bentonite with different moisture content and particle size.

[0030] The side frame on one side of the outer shell and the guide frame on the other side form a symmetrical support structure. The top cover, which is slidably mounted on the guide frame, can move horizontally along the guide frame. The bottom surface of the top cover slides and fits against the upper surface of the outer shell, so that the top of the outer shell can be opened and closed and sealed. When stirring, the top cover closes to prevent dust generated by stirring from escaping from the top. When maintenance or cleaning is required, the top cover can slide open along the guide frame for easy operation.

[0031] The other end of the top cover is connected to the side frame via a horizontal linear drive (such as an electric push rod). The linear drive can automatically open and close the top cover, improving ease of operation. The bottom cover at the bottom of the outer shell is connected to the interior of the outer shell and can collect the bentonite after mixing. The discharge auger inside the bottom cover is driven by electricity to rotate, with one end extending into the discharge pipe on one side of the bottom cover. It can directionally transport the material in the bottom cover along the discharge pipe to the external collection device, avoiding material accumulation and blockage in the bottom cover. The dust collection hood at the top of the top cover is connected to the interior of the outer shell, and the suction pipe at the top can be connected to the external negative pressure equipment. When the negative pressure equipment is activated during the mixing process, the residual dust in the outer shell can be extracted through the dust collection hood and suction pipe, further reducing dust pollution. During operation, the top cover is closed, and the stirring shaft drives the stirring frame to rotate and stir the materials. After stirring is completed, the discharge auger starts, conveying the materials out through the discharge pipe. During the stirring process, the dust collection hood sucks up dust. Dual-shaft stirring ensures uniformity, the top cover seal and dust collection hood work together to prevent dust, and the discharge auger ensures directional conveying. All components work together to achieve stirring, improving stirring efficiency and the quality of the working environment.

[0032] For example, such as Figure 3 As shown, the stirring rack is composed of several supports, and the cross-section of each support of the stirring rack is Y-shaped.

[0033] In some examples, the mixing rack consists of several supports, all with a Y-shaped cross-section. This design significantly improves the mixing uniformity and dispersing effect of bentonite. The bifurcated structure of the Y-shaped supports can create multi-directional cutting and diversion effects on the material during rotation. Compared with traditional straight supports, it can make more full contact with and grasp the bentonite, especially for bentonite that is prone to clumping. The bifurcated tips can quickly break up clumps and avoid leaving any clumps of material.

[0034] For example, such as Figure 3 As shown, both sides of the bottom of the outer shell have arc-shaped transition structures, and both sides of the bottom of the outer shell are inclined towards the bottom cover.

[0035] In some examples, the bottom sides of the outer shell feature arc-shaped transition structures that slope towards the bottom cover. This design enables residue-free collection and efficient conveying of the mixed material. The arc-shaped transition structure prevents material from accumulating in the corners of the bottom of the outer shell, avoiding material stagnation caused by right-angled structures. The sloping bottom surface towards the bottom cover is guided by gravity, allowing the mixed bentonite to automatically converge towards the bottom cover. This material concentration can be achieved without additional power, reducing the conveying load on the discharge auger inside the bottom cover.

[0036] In practical use: The bentonite raw material is poured into the feeding hopper of the feeding assembly. The conveyor auger is started, transporting the raw material to the feeding hopper at the top of the outer frame. The conveyor belt begins operation, and the surface pushing protrusions pass through the bottom opening of the feeding hopper, receiving the raw material and moving with the conveyor belt. A scraper on the side surface of the feeding hopper removes excess material from the protrusions, ensuring accurate delivery each time. The conveyor belt transports the measured amount of raw material to the top of the outer shell and into the interior. Then, a horizontal linear drive drives the top cover to slide along the guide frame, closing the top of the outer shell. The stirring shaft of the stirring assembly is started, and the Y-shaped stirring frame rotates to thoroughly stir the raw material. During stirring, the dust collection hood collects dust through a suction pipe. After stirring is complete, the discharge auger inside the bottom cover of the outer shell starts, transporting the uniformly mixed bentonite along the discharge pipe to the external collection device. The entire process achieves automatic quantitative feeding and efficient stirring, eliminating the need for manual weighing and proportioning.
