Description

Technical Field

[0001] This invention relates to the field of bentonite slurry preparation equipment technology, and more particularly to the field of equipment technology for intelligent preparation of slurry based on finished bentonite, specifically to an intelligent bentonite slurry preparation system covering the entire process. Background Technology

[0002] Bentonite drilling mud is a high-viscosity suspension formed by mixing bentonite minerals with water, and it has a wide range of applications. Firstly, in the drilling industry, especially in oil and gas drilling, bentonite drilling mud is used as a drilling fluid to effectively cool the drill bit, remove drill cuttings, and maintain wellbore stability. Secondly, bentonite drilling mud is also commonly used in underground engineering, tunnel construction, and foundation pit excavation to reinforce soil, control seepage, and prevent collapse. Due to its excellent water absorption and swelling properties, bentonite drilling mud also plays an important role in environmental protection, landfilling, and soil improvement.

[0003] The preparation process of bentonite slurry is relatively simple. First, high-quality bentonite ore, usually sodium-based bentonite, is selected. This type of bentonite has high expansibility and good rheological properties. After crushing and screening, the ore is mixed with an appropriate amount of water, typically 2-3 times the weight of the bentonite. During mixing, mechanical stirring or a high-pressure emulsifier can be used to ensure thorough dispersion of the bentonite particles and the formation of a uniform slurry. If necessary, some additives, such as deionized water and surfactants, can be added to improve the slurry's performance. Finally, after a certain period of settling and sedimentation, and removing the supernatant water, a high-viscosity bentonite slurry is obtained and ready for use.

[0004] The most convenient and relatively reliable method for preparing bentonite slurry is using pre-made bentonite. By precisely controlling the proportions, a slurry with a relatively precise density can be obtained. However, the weight of a single bag of pre-made bentonite is measured in tons. The following issues arise when feeding and conveying pre-made ton-bag bentonite:

[0005] 1. Due to the large weight of the ton bags, they are usually manually hoisted and loaded using a gantry crane. Then, the bags are opened manually or by gravity using a spiked structure. This requires additional manpower. The spiked structure can easily cause bentonite to get stuck and result in incomplete material discharge.

[0006] 2. Bentonite is susceptible to moisture. While moisture does not fundamentally affect the quality of the pulp, it can impact the feeding of bentonite and cause jamming and damage to conveying equipment during transport. Based on these problems in the existing technology, this invention was developed. Summary of the Invention

[0007] To address the problem of efficient bentonite slurry preparation, this application provides a fully automated bentonite slurry preparation system that can efficiently prepare bentonite slurry from finished bentonite, and simultaneously solves at least one of the following problems:

[0008] 1. Quickly cut the large-diameter opening at the bottom of the ton bag to rapidly and completely empty the bentonite inside, solving the problem of increased manpower required for manual bag breaking and addressing the issue of slow and incomplete bentonite discharge caused by incomplete puncture of the bag structure.

[0009] 2. Solve the problem of increased viscosity caused by bentonite getting damp, which leads to pipe jamming and pipe bursting during feeding.

[0010] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0011] The intelligent bentonite pulping system includes a control mechanism and a feeding device controlled by the control mechanism for breaking bentonite ton bags to allow the bentonite to enter the hopper at the bottom of the feeding device. The feeding device includes a frame, a feeding mechanism installed on the top of the frame for hoisting and transporting bentonite ton bags, a bag-breaking mechanism located inside the frame and below the feeding mechanism, and a hopper for temporarily storing bentonite located below the bag-breaking mechanism.

[0012] The feeding device is used to transport bentonite from the hopper at the bottom of the feeding device to the pulping device;

[0013] The slurry preparation device is used to fully mix the bentonite conveyed by the feeding device, the water supplied quantitatively by the water supply mechanism, and the reagents supplied quantitatively by the reagent supply mechanism according to the preset slurry ratio to obtain bentonite slurry of preset density.

[0014] To improve bag breaking efficiency and ensure rapid bentonite discharge, avoiding slow or incomplete discharge caused by insufficient bevel of the ton bag, the bag breaking mechanism is preferably mounted on a support frame fixedly connected to the machine frame. The bag breaking mechanism includes a support flap, one end of which is hinged to at least one support column fixedly mounted on the support frame via a first axis, and the other end of which is hinged to at least one telescopic column fixedly mounted on the support frame via a second axis. The first and second axes are spatially parallel. A cutting unit extending from the upper surface of the support flap is installed at the bottom of the support flap for cutting the bentonite ton bag.

[0015] To improve the feeding speed, ensure that the opening of the bag is large enough, and prevent the ton bag from sliding off-center, preferably, the support flap is provided with multiple rollers protruding from the upper surface of the support flap. The support flap includes a base plate and side plates fixed on both sides of the base plate, forming a U-shaped space for accommodating bentonite ton bags.

[0016] To achieve autonomous cutting while also ensuring energy efficiency, the system preferably includes a switching mechanism located inside the telescopic column or between the support flap and the support column for controlling the opening and closing of the cutting unit.

[0017] More preferably, the switching mechanism includes controlling the separation / contact of the first contact part and the second contact part by extending / retracting the telescopic column or flipping the support flap, thereby realizing the closing / opening control of the cutting unit.

[0018] To address the problem of bentonite easily getting stuck and bursting after absorbing moisture, the feeding device preferably includes a feeding motor and a screw conveyor connected to the feeding motor. A first water pipe for supplying water to the screw conveyor is also installed on the outer wall of the screw conveyor. The first water pipe has multiple one-way branch pipes that communicate with the inside of the screw conveyor. The other end of the first water pipe is connected to the water supply mechanism through a first flow meter.

[0019] In a further preferred embodiment, the outlet end of the water supply mechanism is connected to the first water pipe and the second water pipe that supplies water to the pulping device, respectively. The second water pipe is equipped with a second flow meter, and both the first flow meter and the second flow meter are electrically connected to the control mechanism.

[0020] Preferably, the pulping device includes a pulping tank, a stirring mechanism disposed inside the pulping tank, the bottom of the pulping tank being connected to the equipment base via at least one weighing sensor, and the weighing sensor being electrically connected to the control mechanism.

[0021] To avoid problems such as feeding jamming, pipe bursting, and machine failure, the present invention also provides a feeding device with another structure. Specifically, the feeding device includes a feeding motor, a screw conveyor driven and connected to the feeding motor, and an air pipe installed on the outer wall of the screw conveyor to supply high-pressure gas into the screw conveyor. The air pipe is provided with multiple air supply branch pipes with one-way valves that communicate with the inside of the screw conveyor. The air pipe is connected to an air compressor.

[0022] To enable more efficient and convenient loading of bentonite ton bags, the loading mechanism preferably includes a crossbeam fixedly mounted on the top of the frame, one end of which extends outward to the outside of the frame by at least one meter. A sliding mechanism that reciprocates along the crossbeam is provided on the crossbeam, and a lifting mechanism is connected to the lower end of the sliding mechanism. A hooking mechanism for hooking or binding bentonite ton bags is connected to the lower end of the lifting mechanism.

[0023] Beneficial effects:

[0024] This invention uses a bottom-adaptive sliding cutting method to break the bag, which can quickly and completely rupture the bottom of the ton bag, making the bag breaking fast, complete and reliable. The bentonite falls from the bottom of the ton bag and is discharged, effectively solving the problem of slow and incomplete discharge of bentonite caused by small and irregular bevels.

[0025] This invention addresses problems such as screw conveyor jamming and pipe bursting caused by the high viscosity of damp bentonite by improving the screw conveyor and incorporating high-pressure gas or water. Attached Figure Description

[0046] Example 1:

[0047] See the instruction manual appendix Figures 1-7 As shown, this embodiment provides a fully automated bentonite pulping system, including a control mechanism 4 and a feeding device 1 controlled by the control mechanism 4, used to break the bentonite ton bags 6 so that the bentonite enters the hopper at the bottom of the feeding device 1; the feeding device 1 includes a frame 11, a feeding mechanism 12 installed on the top of the frame 11 for hoisting and transporting the bentonite ton bags 6, a bag-breaking mechanism 13 located inside the frame 11 and below the feeding mechanism 12, and a hopper for temporarily storing the bentonite below the bag-breaking mechanism 13;

[0048] Feeding device 2 is used to transport bentonite in the hopper at the bottom of feeding device 1 to pulping device 3;

[0049] The slurry preparation device 3 is used to fully mix the bentonite conveyed by the feeding device 2, the water supplied quantitatively by the water supply mechanism 5, and the reagent supplied quantitatively by the reagent supply mechanism according to the preset slurry ratio to obtain a bentonite slurry of preset density.

[0050] Working principle:

[0051] The finished bentonite ton bag 6 is lifted by the feeding mechanism 12 at the top of the feeding device 1, then hoisted and transported to the bag-breaking mechanism 13. The bentonite ton bag 6 is then slowly lowered onto the bag-breaking mechanism 13 to complete the bag breaking. After breaking, the bentonite falls naturally into the hopper at the bottom of the feeding device 1 under gravity, awaiting delivery to the pulping device 3. The bag-breaking mechanism can be a puncture-type mechanism, such as using an enlarged structure with spikes to puncture the bottom of the ton bag to allow material leakage; it can also be a heating-type mechanism, using a high-temperature structural component to create an opening at the bottom of the ton bag for the bentonite to fall; or it can be a cutting-type mechanism, using a sharp structure to easily cut the ton bag, such as a rotating blade or grinding wheel, to cut the bottom of the ton bag. In this embodiment, the specific structure of the bag-breaking mechanism 13 is not limited; those skilled in the art can choose a suitable structure for bag breaking.

[0052] The feeding device 2 transports the bentonite from the silo to the pulping device 3. The pulping device 3, through the control mechanism 4, mixes and stirs the bentonite, water, and reagents according to a preset ratio. After stirring, the slurry is discharged through the pulping device 3 to a subsequent sedimentation tank, completing the pulping process. Compared to existing pulping equipment, this invention eliminates the need for manual transportation and bag breaking, achieving a high degree of automation. Most importantly, it can adaptively break the heavy bentonite ton bags 6 from the bottom, offering advantages such as a large opening, fast discharge, and no residue.

[0053] Example 2:

[0054] To improve bag breaking and ensure rapid bentonite feeding, avoiding slow and incomplete feeding caused by insufficient bag bevel, this embodiment further optimizes the structural design based on Embodiment 1. For details, please refer to the appendix of the instruction manual. Figures 1-9 As shown, the bag-breaking mechanism 13 is mounted on a support frame 14 fixedly connected to the frame 11. The bag-breaking mechanism 13 includes a support flap 131. One end of the bottom of the support flap 131 is hinged to at least one support column 133 fixedly mounted on the support frame 14 at a first axis. The other end of the support flap 131 is hinged to at least one telescopic column 134 fixedly mounted on the support frame 14 at a second axis. The first axis and the second axis are spatially parallel. A cutting unit 132 is installed at the bottom of the support flap 131, extending from the upper surface of the support flap 132 for cutting the bentonite ton bag 6.

[0055] Working principle:

[0056] The supporting flap 131 utilizes the weight of the bentonite ton bag 6 as it falls to tilt and break the bag. Specifically, in its initial state, the supporting flap 131... Figure 10 As shown, when the bentonite ton bag 6 is released from the support flap 131 in a horizontal state, under the action of its own weight, since one end of the support flap 131 is a non-extendable support column 133 and the other end is a compressible telescopic column 134, the telescopic column 134 is gradually compressed under the pressure from the bentonite ton bag 6. As the bentonite ton bag 6 continues to fall, the telescopic column 134 is compressed to a greater extent. The support flap 131 tilts downward around the first axial telescopic column 134. As the tilt angle becomes larger, the bentonite ton bag 6 slides downward along the support flap 131. As a result, the bottom of the bentonite ton bag 6 will pass through the bag-breaking mechanism 13, which will cut a large opening in the bottom of the bentonite ton bag 6. As the ton bag is cut open, the bentonite inside tilts down and finally falls into the hopper at the bottom of the feeding device 1, completing the bag breaking and feeding. In this embodiment, the bag-breaking mechanism 13 is in a long-term working state. Alternatively, the starting or stopping of the bag-breaking mechanism 13 can be controlled by the control mechanism 4 according to the position of the feeding mechanism 12.

[0057] To improve the feeding speed, ensure a sufficiently large opening for the bag to be opened, and prevent the ton bag from sliding off-center, this embodiment refers to... Figures 9-12 As shown, the supporting flap 131 is provided with a plurality of rollers 1313 protruding from the upper surface of the supporting flap 131. The supporting flap 131 includes a base plate 1312 and side plates 1311 fixedly disposed on both sides of the base plate 1312, forming a U-shaped space 1314 for accommodating the bentonite ton bag 6. The bentonite ton bag 6 will naturally stay in the U-shaped space 1314 and slide down the supporting flap 131 to the lower end. This prevents the bentonite ton bag 6 from tilting or sliding off the side of the supporting flap 131.

[0058] Example 3:

[0059] In order to achieve autonomous cutting while taking into account the energy efficiency of cutting, this embodiment is further improved on the basis of embodiment 2. Specifically, it also includes a switching mechanism disposed in the telescopic column 134 or between the support flap 131 and the support column 133 for controlling the opening or closing of the cutting unit 132.

[0060] In this embodiment, the switching mechanism includes controlling the separation / contact of the first contact part 1343 and the second contact part 1345 by extending / retracting the telescopic column 134 or flipping the support flap 131, thereby realizing the closing / opening control of the cutting unit 132.

[0061] During the descent of the bentonite ton bag 6, the support flap 131, through the extension and retraction of the telescopic column 134, controls the separation / contact of the first contact part 1343 and the second contact part 1345, thereby achieving the on / off control of the cutting unit 132. Thus, as long as the bentonite ton bag 6 does not exert pressure on the support flap 131, the cutting unit 132 remains inactive and consumes no energy; the cutting unit 132 is only activated after the bentonite ton bag 6 tilts due to its descent. This significantly shortens the working time of the cutting unit 132 and greatly reduces energy consumption without affecting the effective breaking of the bag. Of course, under the inventive concept provided in this embodiment, the supporting columns 133 can also be used to support the supporting flap 131. This prevents the supporting flap 131 from flipping over and instead fixes it directly to the support frame 14. The supporting flap 1313 remains in an inclined state, and the bentonite ton bag 6 can slide down along the supporting flap 131. Under this fixed structure, the cutting unit 132 will no longer use adaptive switch control but will be in a normally open state. It will only be closed after the feeding process is completely completed. This consumes more energy than the adaptive opening / closing through the switch mechanism provided above, but the structure is simpler. Both are subdivided parallel solutions to the problem of bag breaking under the overall inventive concept of this invention.

[0062] Example 4:

[0063] To address the issue of bentonite easily becoming stuck and bursting after absorbing moisture, this embodiment refers to... Figure 4 As shown, the feeding device 2 includes a feeding motor 21 and a screw conveyor 22 driven by the feeding motor 21. A first water pipe 23 is installed on the outer wall of the screw conveyor 22 to supply water to the inside of the screw conveyor 22. Multiple one-way branch pipes 24 communicating with the inside of the screw conveyor 22 are provided on the first water pipe 23. The other end of the first water pipe 23 is connected to the water supply mechanism 5 through a first flow meter 25. In this embodiment, compared with the prior art, the difference is that a first water pipe 23 is added to the screw conveyor 22 to selectively inject water into the screw conveyor 22 through the one-way branch pipes 24. This allows the bentonite inside the screw conveyor 22 to receive effective water lubrication, avoiding problems such as bentonite jamming and pipe bursting caused by the bentonite becoming damp and sticky due to the excessive length of the outlet and inlet ends of the screw conveyor 22. After water is introduced, the water flow rate is collected by the first flow meter 25, ensuring that no matter how much water is introduced through the screw conveyor 22 during the feeding process, the overall water ratio will not be too high. When water is not needed to transport bentonite, the one-way branch pipe 24 can also effectively prevent bentonite from entering the first water pipe 23, achieving two goals at once.

[0064] It is particularly important to emphasize that the improved screw conveyor 22 achieves water-soil mixing during the feeding process. This effectively solves the problem of bentonite sticking to the inside of the screw conveyor after becoming damp, which prevents proper feeding and increases the working resistance of the screw conveyor 22, leading to problems such as motor burnout, screw blade deformation, or pipe bursting. During the conveying process, after water is added, the damp bentonite, stirred by the screw blades, will not stick to the inner wall of the screw conveyor 22's pipe. Instead, it will gradually change from a solid to a clump-like solid-liquid mixture. With further mixing and stirring by the screw conveyor, it will gradually transform into a paste or viscous state. However, when it finally exits from the outlet of the screw conveyor 22, regardless of its state, there will be no problem of bentonite getting stuck in the pipe. This ensures effective bentonite conveying and fundamentally solves the problem of damp bentonite causing pipe jamming and preventing conveying.

[0065] Example 5:

[0066] This embodiment, based on Embodiment 4, addresses the issue of excessive moisture content caused by the improved pre-watering method used in this invention to enhance material feeding smoothness. This embodiment employs a flow control and diverted water supply structure, diverting water flow in stages and at different times. This aims to ensure smooth feeding of damp bentonite without affecting the bentonite slurry ratio, thus resolving the jamming problem. Specifically, the outlet of the water supply mechanism 5 is connected to the first water pipe 23 and a second water pipe supplying water to the slurry preparation device 3. A second flow meter (not shown in the figure) is installed on the second water pipe. Both the first flow meter 25 and the second flow meter are electrically connected to the control mechanism 4. The first water pipe 23 and the second water pipe, respectively, are monitored by the first flow meter 25 and the second flow meter, ensuring precise injection according to the preset water-to-soil ratio without affecting the preset water-to-soil ratio in the slurry preparation. Since the water from the first water pipe 23 and the second water pipe is injected into the pulping device 3 through the screw conveyor 22 and directly into the pulping device 3 respectively, the sum of the water flow in the first flow meter 25 and the second flow meter is taken as the total amount of water injected into the pulping device 3. This can effectively ensure that the amount of water for pulping can be accurately controlled and pulping is carried out according to the preset water content of the mud. The principle of diverting water injection to solve technical problems such as pipe jamming and pipe bursting has been described in detail in Example 4, and will not be repeated in this embodiment.

[0067] Example 6:

[0068] This embodiment is based on any of the above embodiments and further refers to the appendix to the specification. Figures 1-7As shown, the pulping device 3 includes a pulping tank and a stirring mechanism disposed inside the pulping tank. The bottom of the pulping tank is connected to the equipment base via at least one weighing sensor, and the weighing sensor is electrically connected to the control mechanism 4. The function of the weighing sensor is to accurately control the material ratio. Since there are only three materials in the pulping process: bentonite, water, and chemical reagents, such as alkali solution, and since the chemical reagents and water are liquids, the total amount injected can be accurately measured using a flow meter or flow pump, the only one that cannot be accurately measured is bentonite. Therefore, the total mass of the mixture obtained by the weighing sensor, minus the mass of the injected water and chemical reagents, yields the mass of the injected bentonite. This ensures that whether the bentonite is damp or not does not affect the accuracy of the pulping formula.

[0069] Example 7:

[0070] To avoid problems such as feeding jams, pipe bursts, and machine malfunctions, this invention also provides a feeding device 2 with an alternative structure to the water-based solution for pipe jamming in Embodiment 4. Specifically, see [link to related documentation]. Figures 3-4 As shown, the feeding device 2 includes a feeding motor 21 and a screw conveyor 22 driven by the feeding motor 21. An air pipe is also installed on the outer wall of the screw conveyor 22 to supply high-pressure gas into the screw conveyor 22. Multiple air supply branches with one-way valves are installed on the air pipe, which communicate with the inside of the screw conveyor 22. The air pipe is connected to an air compressor. For bentonite that is not heavily moist and does not have significant adhesion, ventilation can effectively discharge the bentonite at the end of the screw conveyor 22, allowing it to quickly enter the pulping device 3. This avoids the problem of bentonite accumulating in the screw conveyor 22 due to insufficient dryness and lack of smoothness.

[0071] To enable more efficient and convenient loading of bentonite ton bags, preferably, the loading mechanism 12 includes a crossbeam 124 fixedly mounted on the top of the frame 11. One end of the crossbeam 124 extends outward to the outside of the frame 11 by at least 1 meter. A sliding mechanism 121 is provided on the crossbeam 124 and moves back and forth along the crossbeam 124. A lifting mechanism 122 is connected to the lower end of the sliding mechanism 121. A hooking mechanism 123 for hooking or binding bentonite ton bags 6 is connected to the lower end of the lifting mechanism 122.

[0072] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
