Description

Technical Field

[0001] The invention relates to the technical field of bentonite slurry preparation equipment, in particular to the technical field of equipment for intelligently preparing slurry based on finished bentonite, and specifically to a full-process bentonite intelligent slurry making system. Background Art

[0002] Bentonite mud is a high-viscosity suspension formed by mixing bentonite minerals with water, which is widely used in many fields. First of all, in the drilling industry, especially in the drilling process of oil and gas, bentonite mud is used as a drilling fluid, which can effectively cool the drill bit, remove drill cuttings, and maintain the stability of the well wall. In addition, bentonite mud is also commonly used in underground engineering, tunnel construction and foundation pit excavation to strengthen the soil, control water seepage and prevent landslides. Due to its excellent water absorption and expansion properties, bentonite mud also plays an important role in environmental protection, waste landfill and soil improvement.

[0003] The preparation process of bentonite slurry is relatively simple. First, select high-quality bentonite ore, usually sodium bentonite, which has high expansibility and good rheological properties. After the ore is crushed and screened, it is mixed with an appropriate amount of water, usually 2-3 times the weight of the bentonite. During the mixing process, mechanical stirring or high-pressure emulsifier can be used to fully stir to ensure that the bentonite particles are completely dispersed and form a uniform slurry. During this process, some additives such as deionized water and surfactants can be added if necessary to improve the performance of the slurry. Finally, after a certain period of standing and settling, the upper layer of clear water is removed to obtain a high-viscosity bentonite slurry that is ready for use.

[0004] The most convenient way to prepare bentonite slurry, and the slurry quality is relatively reliable, is to use finished bentonite for preparation. By accurately controlling the proportion, a slurry with a relatively accurate density can be obtained. However, the weight of a single bag of finished bentonite is measured in tons. For the feeding and transportation of finished ton bags of bentonite, there are the following problems:

[0005] 1. Ton bags are heavy, and are usually loaded manually by a gantry crane, and then broken manually or by using a spike structure based on gravity. This requires additional human resources. The spike structure bag breaking is prone to bentonite jamming and incomplete material discharge.

[0006] 2. Bentonite is easily affected by moisture. Although the bentonite affected by moisture does not have a fundamental impact on the quality of pulping, it will affect the feeding of bentonite and easily cause problems such as jamming and damage to the conveying equipment during the conveying of bentonite. Based on the above problems existing in the prior art, the present invention is specially completed. Summary of the invention

[0046] Embodiment 1:

[0047] See the instruction manual Figure 1-Figure 7 As shown, this embodiment provides a full-process bentonite intelligent pulping system, including a control mechanism 4, and also includes a feeding device 1 controlled by the control mechanism 4, which is used to break the bentonite ton bag 6 so that the bentonite enters the silo 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 bag 6, and a bag breaking mechanism 13 arranged in the frame 11 and located below the feeding mechanism 12, and the silo for temporarily storing bentonite is arranged below the bag breaking mechanism 13;

[0048] A feeding device 2, used for conveying bentonite in the silo at the bottom of the feeding device 1 to the pulping device 3;

[0049] The slurry making device 3 is used to fully mix the bentonite delivered by the feeding device 2, the water quantitatively supplied by the water supply mechanism 5, and the reagent quantitatively supplied by the reagent supply mechanism according to a preset slurry ratio to obtain 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, and then hoisted and transported to the top of the bag breaking mechanism 13, and the bentonite ton bag 6 is slowly lowered to the bag breaking mechanism 13 to complete the bag breaking. After the bag is broken, under the action of gravity, the bentonite naturally falls into the silo at the bottom of the feeding device 1, waiting to be transported to the pulping device 3. Among them, the bag breaking mechanism can adopt a puncture-type bag breaking mechanism, such as using an enlarged structure with a sharp thorn part to puncture the bottom of the ton bag to leak the material, so as to achieve the purpose of breaking the bag and taking the bentonite; a heating-type bag breaking mechanism can also be adopted, that is, a high-temperature structural part is used to burn a hole at the bottom of the ton bag for the bentonite to fall; a cutting-type bag breaking mechanism can also be adopted, that is, a sharp structure that is easy to cut the ton bag, such as a rotating blade or a grinding wheel, is used to cut the bottom of the ton bag. In this embodiment, the specific structure of the bag breaking mechanism 13 is not limited, and those skilled in the art can select a suitable structure for bag breaking.

[0052] The feeding device 2 transports the bentonite in the silo to the pulping device 3. The pulping device 3 mixes and stirs the bentonite, water and reagent according to a preset ratio through the control mechanism 4. After the stirring is completed, the slurry is discharged to the subsequent sedimentation tank through the pulping device 3 to complete the pulping. Compared with the existing pulping equipment, the present invention does not require manual transportation and bag breaking, and has a high degree of automation; the most critical thing is that the bentonite ton bag 6 with a larger weight can be adaptively broken from the bottom, and breaking the bag from the bottom has the advantages of a large bag breaking gap, fast material discharge, and no residue.

[0053] Embodiment 2:

[0054] In order to better break the bag, the bentonite can be quickly discharged, avoiding the problem of slow discharge and incomplete discharge caused by the insufficient bevel of the ton bag. This embodiment further optimizes the structural design based on the embodiment 1. Specifically, see the attached manual Figure 1-Figure 9 As shown, the bag breaking mechanism 13 is installed on a support frame 14 fixedly connected to the frame 11, and the bag breaking mechanism 13 includes a supporting flap 131, and one end of the bottom of the supporting flap 131 is hinged to a first axis with at least one supporting column 133 fixedly installed on the supporting frame 14, and the other end of the supporting flap 131 is hinged to a second axis with at least one telescopic column 134 fixedly installed on the supporting frame 14, and the first axis is spatially parallel to the second axis, and a cutting unit 132 extending from the upper surface of the supporting flap 132 for cutting the bentonite bulk bag 6 is installed at the bottom of the supporting flap 131.

[0055] Working principle:

[0056] The supporting flap 131 utilizes the weight of the bentonite bag 6 when it falls to tilt and break the bag. Specifically, the supporting flap 131 is in the initial state as shown in FIG. Fig.10 As shown, it is in a horizontal state. After the bentonite bag 6 is lifted to the supporting flap 131, under the action of its own gravity, since one end of the bottom of the supporting flap 131 is a non-retractable supporting column 133, and the other end is a retractable column 134 that can be compressed under force, after being subjected to the pressure from the bentonite bag 6, the retractable column 134 is gradually compressed, and as the bentonite bag 6 continues to fall, the retractable column 134 is compressed to a greater extent, and the supporting flap 131 tilts downward around one side of the first axial retractable column 134. As the tilting and deflecting angle becomes larger and larger, the bentonite bag 6 slides downward along the supporting flap 131, so that the bottom of the bentonite bag 6 passes through the bag breaking mechanism 13, so that a large hole is cut at the bottom of the bentonite bag 6. As the bag is cut open, the bentonite in the bag tilts downward and finally falls into the silo at the bottom of the feeding device 1, completing the bag breaking and unloading. In this embodiment, the bag breaking mechanism 13 is in a long-term working state, and the start or stop of the bag breaking mechanism 13 can also be controlled by the control mechanism 4 according to the position of the feeding mechanism 12.

[0057] In order to increase the speed of material discharge, ensure that the opening of the broken bag is large enough, and avoid the skewed direction of the ton bag sliding, etc., in this embodiment, refer to Figure 9-12 As shown, the support flap 131 is provided with a plurality of rollers 1313 protruding from the upper surface of the support flap 131, and the support flap 131 includes a bottom plate 1312 and side plates 1311 fixedly arranged on both sides of the bottom plate 1312, and forms 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 naturally along the support flap 131 to the lower end. This prevents the bentonite ton bag 6 from tilting or sliding off the side of the support flap 131.

[0058] Embodiment 3:

[0059] In order to realize autonomous cutting while taking into account the energy saving of cutting, this embodiment is further improved on the basis of Embodiment 2, and specifically also includes a switch mechanism for controlling the opening or closing of the cutting unit 132 arranged in the telescopic column 134 or between the supporting flap 131 and the supporting column 133.

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

[0061] During the falling process of the bentonite ton bag 6, the support flap 131 controls the separation / contact of the first contact portion 1343 and the second contact portion 1345 through the telescopic action of the telescopic column 134 during the turning process, thereby realizing the closing / opening control of the cutting unit 132. In this way, as long as there is no pressure exerted by the bentonite ton bag 6 on the support flap 131, the cutting unit 132 is always in a non-working state and does not generate energy consumption; the cutting unit 132 is only started after the bentonite ton bag 6 falls and causes the support flap 131 to tilt, which greatly shortens the working time of the cutting unit 132 and greatly reduces energy consumption, but does not affect the effective bag breaking. Of course, under the inventive concept provided in this embodiment, the support columns 133 can also be used to support the support flap 131, which makes it impossible for the support flap 131 to flip over, but directly fixed on the support frame 14, and the support flap 1313 remains in an inclined state, and the bentonite bag 6 can slide along the support 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 loading process is completely completed. Compared with the adaptive on / off through the switch mechanism provided above, this has relatively higher energy consumption, but the structure is simpler. They all belong to the subdivided parallel solution to bag breakage under the overall concept of the invention.

[0062] Embodiment 4:

[0063] In order to solve the problem that bentonite is prone to sticking and bursting after being damp, in this embodiment, refer to Figure 4 As shown, the feeding device 2 includes a feeding motor 21, a screw conveyor 22 drivingly connected to the feeding motor 21, and a first water pipe 23 for supplying water to the screw conveyor 22 is installed on the outer wall of the screw conveyor 22, and a plurality of one-way branches 24 communicating with the inside of the screw conveyor 22 are arranged on the first water pipe 23, and the other end of the first water pipe 23 is communicated with 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 24, so that the bentonite in the screw conveyor 22 can be effectively lubricated with water, avoiding problems such as bentonite jamming and pipe bursting caused by the excessive length between the outlet end and the feed end of the screw conveyor 22 and the stickiness of the bentonite due to moisture. After the water is passed, the water flow rate is collected by the first flow meter 25, so that during the feeding process, no matter how much water is passed through the screw conveyor 22, it will not cause the problem of a high water ratio in the overall mix. When there is no need to pass water to transport bentonite, the one-way branch pipe 24 can also effectively prevent bentonite from entering the first water pipe 23, killing two birds with one stone.

[0064] It is particularly important to emphasize that the improved screw conveyor 22 achieves water-soil mixing during the feeding process, which can effectively solve the problem that the bentonite sticks to the inside of the screw conveyor after getting damp, resulting in the inability to feed the bentonite normally, which increases the working resistance of the bolt conveyor 22, thereby causing the burning of the motor, deformation of the spiral blades, or bursting of the pipe. During the transportation process, after the addition of water to the bentonite, as the spiral blades are stirred, the damp bentonite will not stick to the inner wall of the pipe of the screw conveyor 22, but will gradually change from a solid to a lump-like solid-liquid mixture, and will gradually transform into a paste or viscous state as the screw conveyor mixes and stirs; but when it is finally discharged from the outlet of the screw conveyor 22, no matter what state it is in, the problem of bentonite stuck in the pipe will not occur, and the bentonite can be effectively transported, thereby fundamentally solving the problem of damp bentonite stuck in the pipe, resulting in the inability to transport.

[0065] Embodiment 5:

[0066] This embodiment is based on the embodiment 4. In order to solve the problem of high moisture content caused by the specially improved advance water injection to improve the smoothness of feeding, this embodiment adopts a flow control and diversion water supply structure to divert, divide and inject water in stages, aiming to achieve the effect of smooth feeding of damp bentonite without affecting the bentonite slurry ratio, and solve the problem of stagnation. Specifically, the outlet end of the water supply mechanism 5 is respectively connected to the first water pipe 23 and the second water pipe that supplies water to the pulping device 3. The second water pipe is provided with a second flow meter, which is not shown in the figure. The first flow meter 25 and the second flow meter are both electrically connected to the control mechanism 4. The first water pipe 23 and the second water pipe are respectively counted by the first flow meter 25 and the second flow meter, and can be accurately injected according to the preset water ratio without affecting the preset water-soil ratio of pulping. Since the water in the first water pipe 23 and the second water pipe is respectively injected into the pulping device 3 through the screw conveyor 22 and directly, the sum of the water flow rates in the first flow meter 25 and the second flow meter is used 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 moisture content of the mud. The principle of diversion water injection to solve technical problems such as pipe sticking and pipe burst has been detailed in Example 4 and will not be repeated in this example.

[0067] Embodiment 6:

[0068] This embodiment is based on any of the above embodiments and further combines the appendix of the specification Figure 1-Figure 7As shown, the pulping device 3 includes a pulping barrel, a stirring mechanism arranged in the pulping barrel, and the bottom of the pulping barrel is connected to the equipment base through at least one weighing sensor, and the weighing sensor is electrically connected to the control mechanism 4. The role of the weighing sensor is to accurately control the material ratio. Since there are only three kinds of pulping materials, one is bentonite, one is water, and the other is a chemical reagent, such as alkali solution; since the chemical reagent and water are both liquid, the total amount of dosage that can be accurately injected through a flow meter or a flow pump is the only thing that cannot be accurately measured is bentonite. Therefore, the total mass of the mixed material obtained by the weighing sensor, minus the mass of the injected water and chemical reagents, can obtain the mass of the injected bentonite, so that whether the bentonite is damp or not will not affect the accuracy of the pulping formula.

[0069] Embodiment 7:

[0070] In order to avoid the problems of feeding jam, pipe burst and machine crash, the present invention also provides another feeding device 2 for replacing the solution of solving the pipe jam problem by water injection in embodiment 4. Specifically, see Figure 3-Figure 4 As shown, the feeding device 2 includes a feeding motor 21, a screw conveyor 22 connected to the feeding motor 21, and an air pipe for providing high-pressure gas to the screw conveyor 22 is installed on the outer wall of the screw conveyor 22. The air pipe is provided with a plurality of air supply branches with one-way valves connected to the inside of the screw conveyor 22, and the air pipe is connected to an air compressor. For bentonite that is not significantly damp and not sticky, the bentonite at the end of the screw conveyor 22 can be effectively discharged by ventilation, so that it can quickly enter the pulping device 3, avoiding the problem of bentonite silting in the screw conveyor 22 due to insufficient dryness and lack of smoothness.

[0071] In order to load the ton bags more efficiently and conveniently, preferably, the loading mechanism 12 includes a beam 124 fixedly arranged on the top of the frame 11, one end of the beam 124 extends outward to the outside of the frame 11 by at least 1 meter, and a sliding mechanism 121 that reciprocates along the beam 124 is arranged on the beam 124, and a lifting mechanism 122 is connected to the lower end of the sliding mechanism 121, and a hooking mechanism 123 for hooking or tying the bentonite ton bags 6 is connected to the lower end of the lifting mechanism 122.

[0072] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
