Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy project construction equipment, in particular to the technical field of auxiliary facilities and equipment for geological construction, and specifically to a bentonite ton bag breaking device. Background Art
[0002] Bentonite mud, a suspension of bentonite minerals mixed with water, is widely used in civil engineering, mining, and oil drilling. Its primary functions include providing support and stability, sealing pores, controlling fluid pressure, and lubricating and cooling the drill bit. During drilling, bentonite mud forms a protective film on the borehole wall, preventing soil or rock collapse and maintaining stability. It also effectively traps groundwater and other fluids, thereby controlling fluid pressure within the well and preventing dangerous situations such as blowouts. Furthermore, bentonite mud exhibits excellent rheological properties, reducing friction and energy consumption during drilling. It also removes cuttings generated during drilling through its flow, maintaining a clean wellbore. Its excellent water absorption and expansion properties allow it to rapidly expand in volume upon contact with water, further enhancing its sealing and stability, making it crucial in a variety of complex geological conditions. Therefore, bentonite mud is not only an indispensable material in drilling operations but also a crucial component in ensuring project safety and efficiency.
[0003] The production of bentonite slurry generally adopts the standardized configuration of finished bentonite according to a specific ratio to obtain bentonite slurry of reliable quality. The finished bentonite is packaged in tons of bags. During the process of making the slurry, the bentonite in the ton bags needs to be poured out. However, due to the excessive weight of a single bag of bentonite, pouring is difficult. In order to improve the efficiency of bentonite pouring, the present invention is specially completed. Utility Model Content
[0004] In order to solve the problem of bentonite dumping during the production of bentonite slurry, the present application provides a bentonite ton bag breaking device for quickly breaking open the bentonite ton bag so that the bentonite in the ton bag can quickly enter the silo to participate in the preparation of bentonite slurry.
[0005] In order to achieve the above objectives, the technical solutions adopted in this application are:
[0006] The utility model provides a bentonite ton bag breaking device, including a supporting frame, on which is installed a lifting and hoisting mechanism for lifting the ton bag to be broken and placing it above the bag breaking mechanism, the bag breaking mechanism including a bracket fixedly installed on the supporting frame, on which are respectively fixedly installed a fixed column and a telescopic column for supporting the ton bag, the upper ends of the fixed column and the telescopic column are hinged to the bottom plate of the bag breaking mechanism; the bag breaking mechanism includes a cutting mechanism arranged on the bottom plate near one end of the telescopic column for breaking the bag by rotation, and when the ton bag falls, the bottom plate deflects, tilts and slides toward one end of the telescopic column with the hinge center of the upper end of the fixed column as the axis, and the bag is cut and broken by the cutting mechanism.
[0007] To improve the smoothness of the ton bag's descent and reduce frictional resistance during the descent, the bag-breaking mechanism preferably includes a plurality of rollers disposed on the base plate to reduce friction between the ton bag and the base plate. The rollers can be arranged on the base plate in a regular or irregular array. The greater the density of the rollers, the less resistance the ton bag faces as it slides down the base plate under the force of gravity. The number and size of the rollers can be flexibly set based on the actual size of the ton bag and the bag-breaking requirements.
[0008] To prevent the ton bag from slipping or deforming abnormally during the bag-breaking process, which would affect the bag-breaking efficiency, side guards are preferably fixedly connected to both sides of the bottom plate along the sliding direction of the ton bag to prevent the ton bag from slipping. The side guards can transform the originally straight bottom plate into a U-shaped or approximately open U-shaped structure, allowing the ton bag to slide naturally along the length of the bottom plate under the protection of the side guards, allowing the bottom of the ton bag to smoothly pass through the cutting mechanism, thereby quickly and thoroughly breaking the bag.
[0009] In order to achieve adaptive control and further reduce energy consumption, the bag-breaking mechanism preferably also includes a switch mechanism that controls the rotation or stop of the cutting mechanism by deflecting the telescopic column or the bottom plate. When the ton bag falls onto the bottom plate, the bottom plate will gradually tilt toward one end of the telescopic column as the ton bag continues to fall, thereby gradually compressing the switch mechanism until the switch mechanism is connected, triggering the cutting mechanism to start, and start high-speed rotation to cut the ton bag. After the ton bag is cut, the bentonite inside the ton bag falls out, and the lifting and hoisting mechanism lifts the empty ton bag. The bottom plate returns to its initial state under the elastic force of the telescopic column itself. At this time, the switch mechanism is naturally disconnected, and the cutting mechanism is powered off and shut down, thereby achieving adaptive control of the cutting mechanism starting when the bag is broken and stopping when the bag is not broken.
[0010] In order to better and more reliably control the cutting mechanism, preferably, the switch mechanism is arranged inside the telescopic column, and the telescopic column includes a telescopic rod and a sleeve that are nested and telescopically connected to each other. A spring for resetting the telescopic rod is provided between the bottom of the sleeve and the bottom of the telescopic rod. The switch mechanism includes a first contact portion provided at the bottom of the telescopic rod and a second contact portion provided at the bottom of the sleeve. The telescopic rod drives the first contact portion to move up and down synchronously to achieve contact or separation with the second base portion.
[0011] As another installation method of the switch mechanism, preferably, the switch mechanism can also be installed between the base plate and the fixed column. Specifically, the switch mechanism includes a first contact portion arranged on the base plate and a second contact portion arranged on the fixed column. The base plate deflects up and down with the hinge center of the upper end of the fixed column as the axis, so that the first contact portion contacts or separates from the second base portion.
[0012] Further preferably, in order to facilitate the ground lifting of ton bags and the dumping of broken bentonite ton bags, the lifting and hoisting mechanism includes a suspension beam fixedly arranged on the top of the support frame, the suspension beam extends from the inside to the outside of the support frame, and a lifting mechanism is slidably arranged on the suspension beam, the lifting mechanism includes a lifting drive and a hook structure for hooking the ton bags, and a travel drive for driving the entire lifting mechanism to move back and forth along the suspension beam.
[0013] In order to ensure the complete transportation of bentonite, preferably, a silo for receiving bentonite dropped after the bag is broken is provided at the bottom of the support frame, wrapping materials for preventing the bentonite from leaking are fixedly provided on the four side walls of the support frame, and a silo door is provided on at least one side of the support frame, and any of the silo doors is hinged with a telescopic drive for controlling the opening and closing of the silo door.
[0014] Beneficial effects:
[0015] 1. The utility model adopts a cutting method to cut the bottom of the ton bag into a large size, so that the bag breaking efficiency is high and the bentonite dumping speed is fast. The bentonite in the entire ton bag can be poured out in about 10 seconds; since the bottom of the ton bag is cut into a large size, there is no bentonite residue, and there is no need for secondary dumping and collection, which reduces the subsequent process processing.
[0016] 2. The cutting method adopted by the present invention can solve the shortcomings of ton bags, such as low dumping efficiency and large bentonite residue, which are caused by the fabric material being difficult to puncture or the puncture hole being not large enough.

[0033] Example 1:
[0034] The bentonite ton bag breaking device provided by the utility model is shown in the attached manual. Figure 1-Figure 7 As shown, it includes a support frame 1, on which is installed a lifting and hoisting mechanism for hoisting ton bags 6 that need to be broken and placing them above a bag breaking mechanism 7. The bag breaking mechanism 7 includes a bracket 8 fixedly installed on the support frame 1, on which are fixedly installed fixed columns 75 and telescopic columns 76 for supporting the ton bags 6, respectively. The upper ends of the fixed columns 75 and telescopic columns 76 are hinged to the bottom plate 71 of the bag breaking mechanism 7; the bag breaking mechanism 7 includes a cutting mechanism 74 arranged on the bottom plate 71 near one end of the telescopic column 76 for breaking the bag by rotation. When the ton bag 6 falls, the bottom plate 71 deflects, tilts and slides toward one end of the telescopic column 76 with the hinge center of the upper end of the fixed column 75 as the axis, and the bag is cut and broken by the cutting mechanism 74.
[0035] Explanation of structure and working principle:
[0036] The support frame 1 is the supporting skeleton of the entire device and is the structure that bears the overall force. For a specific embodiment, please refer to Figure 1 The lifting and hoisting mechanism is a structure that lifts the finished bentonite ton bag on the ground and lifts it to the top of the bag breaking mechanism 7, playing the role of transporting a ton bag 6. The bag breaking mechanism 7 is the most critical structure of this embodiment. The process and principle of its bag breaking are as follows:
[0037] The weight of the ton bag 6 filled with bentonite varies according to different specifications, but is calculated in tonnage units. As the lifting and hoisting mechanism gradually lowers the ton bag 6, it will first contact the bottom plate 71 of the bag breaking mechanism 7. Figure 7 When the bag 6 is lowered, the weight of the bag 6 will exert a downward positive pressure on the bottom plate 71. Since the support structure under the bottom plate 71 is composed of telescopic columns 76 and fixed columns 75, and the fixed columns 75 are not elastic, the telescopic columns 76 will be compressed and shortened when receiving the downward pressure. At this time, the bottom plate 71 will slowly tilt toward one end of the telescopic columns 76. As the tilt angle becomes larger and larger, the bag 6 will slide downward along the bottom plate 71 and finally contact the cutting mechanism 74 located on the side of the bottom plate 71 near the telescopic columns 76, so that a large hole is cut in the bottom of the bag 6, and the bentonite tilts down along the cut, thereby completing the unloading of the bentonite. At this time, since the bottom plate 71 is no longer subjected to the pressure exerted by the bag 6, the telescopic columns 76 return to their original length under their own rebound action, and the bottom plate 71 is in a horizontal state. Subsequently, the lifting and hoisting mechanism lifts and recovers the empty bag 6, and then repeats the lifting of another bag of bag 6.
[0038] Example 2:
[0039] In order to improve the smoothness of the ton bag's descent and reduce the friction resistance during the descent, this embodiment further improves the structure on the basis of embodiment 1. Specifically, see Figure 6-Figure 7 As shown, the bag breaking mechanism 7 also includes a plurality of rollers 73 provided on the bottom plate 71 for reducing the friction between the ton bag 6 and the bottom plate 71. The rollers 73 can be arranged on the bottom plate 71 in a regular array or an irregular manner. The greater the density of the rollers 73, the smaller the resistance of the ton bag 6 to sliding down along the bottom plate 71 under the action of gravity. The actual number and size of the rollers 73 can be flexibly set according to the actual size of the ton bag 6 and the bag breaking requirements. The more rollers 73 are set, the smaller the contact area between the surface of the ton bag 6 and the bottom plate 71, and the smaller the friction resistance, so that the ton bag 6 will slide down smoothly under its own gravity. It is worth noting that the bottom plate 71 is preferably made of a wear-resistant material with low friction, such as stainless steel.
[0040] Example 3:
[0041] In order to prevent the ton bag 6 from slipping or abnormal deformation during the bag breaking process, which affects the efficiency of the bag breaking, this embodiment improves the bottom plate 71 based on the above embodiment 1 or 2. Figure 4 As shown, side guards 72 are fixedly connected to both sides of the bottom plate 71 along the sliding direction of the ton bag 6 to prevent the ton bag 6 from sliding sideways. The side guards 72 can transform the originally straight cross-section of the bottom plate 71 into a U-shaped or approximately open U-shaped structure, so that the ton bag 6 can slide naturally along the length direction of the bottom plate 71 under the obstruction of the side guards 72, and the bottom of the ton bag 6 can smoothly pass through the cutting mechanism 74, thereby quickly and thoroughly breaking the bag.
[0042] Example 4:
[0043] In order to achieve adaptive control and further reduce energy consumption, this embodiment performs adaptive control on the cutting mechanism 74 based on any of the above embodiments to avoid unnecessary waste of energy caused by the cutting mechanism 74 being always open. Figures 1-8As shown, the bag-breaking mechanism 7 also includes a switch mechanism that controls the rotation or stop of the cutting mechanism 74 by deflecting the telescopic columns 76 or the bottom plate 71. When the ton bag 6 falls onto the bottom plate 71, the bottom plate 71 will gradually tilt toward one end of the telescopic columns 76 as the ton bag 6 continues to fall, thereby gradually compressing the switch mechanism until the switch mechanism is connected, triggering the cutting mechanism 74 to start, and begin high-speed rotation to cut the ton bag 6. After the ton bag 6 is cut, the bentonite inside the ton bag 6 falls out, and the lifting and hoisting mechanism lifts the empty ton bag 6. The bottom plate 71 returns to its initial state under the self-elastic force of the telescopic columns 76. At this time, the switch mechanism is naturally disconnected, and the cutting mechanism 74 is powered off and shut down, thereby achieving adaptive control of the cutting mechanism 74 starting when the bag is broken and stopping when the bag is not broken.
[0044] In order to better and more reliably control the cutting mechanism 74, this embodiment also provides a specific setting method of the switch mechanism, see Figure 8 As shown, the switch mechanism is arranged inside the telescopic column 76, and the telescopic column 76 includes a telescopic rod 761 and a sleeve 765 that are nested and telescopically connected to each other. A spring 763 for resetting the telescopic rod 761 is provided between the bottom of the sleeve 765 and the bottom of the telescopic rod 761. The switch mechanism includes a first contact portion 762 provided at the bottom of the telescopic rod 761 and a second contact portion 764 provided at the bottom of the sleeve 765. The telescopic rod 761 drives the first contact portion 762 to move up and down synchronously to achieve contact or separation with the second base portion 764.
[0045] As another installation method of the switch mechanism, in this embodiment, the switch mechanism can also be installed between the base plate 71 and the fixed column 75. Specifically, the switch mechanism includes a first contact portion 762 provided on the base plate 71 and a second contact portion 764 provided on the fixed column 75. The base plate 71 deflects up and down with the hinge center of the upper end of the fixed column 75 as the axis, so that the first contact portion 762 contacts or separates from the second base portion 764.
[0046] Example 5:
[0047] This embodiment is an improvement based on any of the above embodiments. Figure 1-Figure 5 As shown, in order to facilitate the ground lifting of ton bags and the dumping of broken bentonite ton bags, the lifting and hoisting mechanism includes a suspension beam 2 fixedly arranged on the top of the support frame 1, and the suspension beam 2 extends from the inside to the outside of the support frame 1. A lifting mechanism 5 is slidably arranged on the suspension beam 2, and the lifting mechanism 5 includes a lifting drive 4 and a hook structure for hooking the ton bags 6, and a travel drive 3 for driving the entire lifting mechanism 5 to move back and forth along the suspension beam 2.
[0048] In order to ensure the complete transportation of bentonite, in this embodiment, a silo 9 is provided at the bottom of the support frame 1 for receiving the bentonite dropped after the bag is broken, and the side walls of the support frame 1 are fixed with wrapping materials to prevent the bentonite from leaking out, as well as a silo door 11 provided on at least one side of the support frame 1. Any of the silo doors 11 is hinged with a telescopic drive 10 for controlling the opening and closing of the silo door 11.
[0049] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
