Description

Technical Field

[0001] This utility model relates to a bag-breaking and anti-clogging rapid feeding device, and more particularly to a closed-type automatic bag-breaking and rapid feeding device for drilling fluid anti-clogging agent, belonging to the field of automatic unpacking technology. Background Technology

[0002] In oil drilling operations, various chemical additives (such as viscosity reducers and filtration reducers) are typically used to regulate drilling fluid properties. Currently, the feeding operation still largely relies on manual unpacking of bags, directly adding powdered additives into the circulation tank. This method has significant limitations: firstly, manual bag unpacking and feeding is inefficient and difficult to meet the continuous feeding requirements of large-scale drilling operations; secondly, the unpacking process easily generates dust, which not only pollutes the working environment but also poses a potential threat to the health of operators. Although some automatic feeding devices can achieve semi-automatic bag-breaking operations, they mostly adopt an open structure design, which still does not effectively solve the problems of dust diffusion and pollution. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] In view of the problems existing in the above and / or prior art, this utility model is proposed.

[0005] The purpose of this invention is to overcome the problems existing in the prior art and provide a closed-type automatic bag-breaking and rapid feeding device for drilling fluid anti-blocking agent. By setting up a separate material preparation area inside the closed shell to store some material bags that need to be unpacked, the material preparation area is used to supply material to the feeding area. This eliminates the need to open the closed shell to feed material from the outside every time the feeding area is fed, thus improving the airtightness during the feeding process.

[0006] To solve the above technical problems, this utility model provides a closed-loop automatic bag-breaking and rapid feeding device for drilling fluid anti-blocking agent, comprising: The sealed shell is divided into a mutually isolated material preparation area and a material loading area. The first feeding channel connects the material preparation area and the feeding area, and is equipped with a first sealing door; The second feeding channel is located on the outer wall of the sealed shell, communicates with the material preparation area, and is equipped with a second sealing door; A material preparation conveyor belt is set in the material preparation area, with its input end corresponding to the second feeding channel and its output end corresponding to the first feeding channel. An automatic bag-breaking mechanism is installed within the feeding area; A conveying mechanism, disposed within the feeding area, is used to convey material bags entering via the first feeding channel to the automatic bag-breaking mechanism; and The material collection hopper is located at the bottom of the feeding area, below the automatic bag breaking mechanism.

[0007] Furthermore, the conveying mechanism includes: The material bag positioning frame is fixedly installed on the lower side of the output end of the material preparation conveyor belt; The movable side panel, together with the bag positioning frame, forms a bag positioning chamber for accommodating vertically placed bags; A side plate lateral movement driver is used to drive the movable side plate to move toward or away from the material bag positioning frame; A pin is disposed on the movable side plate and faces the material bag positioning chamber; and A pin drive mechanism is used to drive the pin to move axially to insert into or detach from the packing.

[0008] Furthermore, a side panel lifter is provided between the movable side panel and the side panel lateral movement driver to drive the movable side panel to perform lifting and lowering movements.

[0009] Furthermore, the automatic bag-breaking mechanism includes: A cutter is positioned at the bottom of the material bag positioning frame; and A cutter driver is disposed within the material bag positioning frame and is used to drive the cutter to reciprocate along the bottom of the material bag positioning frame.

[0010] Furthermore, the bottom of the material bag positioning frame is provided with an upwardly recessed driver mounting groove, in which the cutter driver is fixedly installed; the bottom plate of the material bag positioning frame is provided with a blade movement groove, and the blade edge of the cutter extends from the blade movement groove from bottom to top.

[0011] Furthermore, a waste bag collection area is also provided inside the sealed housing. This waste bag collection area is located to the side of the feeding area, and its position corresponds to the movement path of the side plate transverse drive driving the movable side plate away from the material bag positioning frame.

[0012] Furthermore, the lower part of the side wall of the waste bag collection area is provided with a material bag outlet and a material inlet gate.

[0013] Furthermore, it also includes a feeding conveyor belt disposed outside the sealed housing, with the output end of the feeding conveyor belt facing the second feeding channel.

[0014] Furthermore, a vibrator is provided on the inner wall of the hopper.

[0015] Furthermore, the sealing doors at both the first and second feeding channels are opened and closed by a door drive mechanism.

[0016] Compared with the prior art, the advantages or beneficial effects of this utility model include at least the following: 1. Excellent airtight dustproof performance: By setting up completely independent preparation and loading areas, and with the first and second loading channels equipped with sealed doors, the entire material feeding process is fully enclosed. The second loading channel is only briefly opened when replenishing materials in batches in the preparation area, greatly reducing the chance of dust escaping and effectively protecting the working environment and the health of operators.

[0017] 2. Highly efficient continuous operation capability: The preparation area can pre-store multiple material bags, serving as a "buffer" for the feeding area. This allows the feeding area to continuously and quickly open bags and add material without waiting for frequent external feeding. This design significantly improves overall feeding efficiency and meets the continuous feeding needs of large-scale drilling operations.

[0018] 3. Thorough bag breaking and high residual value: An innovative method is adopted, using pins to fix the top of the bag and cutters at the bottom to break it open. After the bag is fixed, it is lifted and moved laterally by the movable side plate, allowing the material to be fully shaken off under gravity, resulting in thorough unloading. At the same time, the bag breaking action is limited to the bottom cut, minimizing damage to the bag's structure, which helps maintain the integrity of the empty bag and facilitates recycling.

[0019] 4. High degree of automation and reliable operation: It integrates automatic conveying, precise positioning, pin fixing, automatic bag breaking, and waste bag collection, realizing full-process automation from material preparation to waste removal. The mechanism is reasonably designed, and the actuators (such as cylinders / electric cylinders) are driven, resulting in precise and reliable movements, reducing labor intensity and the risk of human error.

[0020] 5. Wide material adaptability: This device is not only suitable for powdered anti-clogging agents, but its bag-breaking and unloading principle is also applicable to the closed-loop addition of granular and even some liquid additives, making it widely applicable. The vibrator installed in the collection hopper further ensures the smooth conveying of materials that are prone to moisture absorption and agglomeration, effectively preventing blockages.

[0021] 6. Easy maintenance and user-friendly design: The cutter driver is installed in an upward-facing recessed groove, forming a natural leak-proof protection that prevents material from corroding the drive components and extends the equipment's lifespan. The waste bag collection area has an independent material inlet door for convenient centralized cleaning of empty bags, simplifying maintenance. Attached Figure Description

[0023] In the following description of this utility model, the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not mean that the device must have a specific orientation.

[0024] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] like Figures 1 to 5 As shown, the drilling fluid anti-blocking agent closed-type automatic bag-breaking and rapid feeding device of this utility model includes a closed shell 1. Inside the closed shell 1, there are independent material preparation area 11 and feeding area 12. The material preparation area 11 is used to place the material bag to be fed, while the feeding area 12 is used to unpack and feed the material.

[0027] The material preparation area 11 and the material feeding area 12 are connected by a first feeding channel 13. A second feeding channel 14 connected to the material preparation area 11 is also provided on the outer wall of the sealed shell 1. Both the first feeding channel 13 and the second feeding channel 14 are provided with a door 15 adapted to them and a door drive mechanism 19 for controlling their opening and closing.

[0028] A feeding conveyor belt 2 is provided outside the sealed housing 1. The output end of the feeding conveyor belt 2 is set towards the second feeding channel 14. A preparation conveyor belt 3 is provided in the preparation area 11. The input end of the preparation conveyor belt 3 is connected to the second feeding channel 14, and the output end of the preparation conveyor belt 3 is connected to the first feeding channel 13. The feeding conveyor belt 2 can accommodate five material bags arranged in sequence.

[0029] An automatic bag-breaking mechanism and a conveying mechanism for transporting the material bags from the material conveyor belt 3 to the automatic bag-breaking mechanism are provided on the upper side of the feeding area 12. A material collection hopper 4 and a conveying mechanism for outputting the material in the material collection hopper 4 are provided at the bottom of the feeding area 12.

[0030] When this device is in operation, a separate material preparation area 11 is set up inside the sealed housing 1, which can be used to store some material bags that need to be unpacked. The material preparation area 11 supplies the material to the feeding area 12, eliminating the need to open the sealed housing 1 to feed material from the outside every time the feeding area 12 is fed. This improves the airtightness during the feeding process and greatly reduces the leakage of dust, gas and other substances during the feeding process.

[0031] In practice, the packages to be unpacked are placed sequentially on the feeding conveyor belt 2. The feeding conveyor belt 2 transports the packages toward the sealed housing 1. During the feeding process of the preparation area 11, the sealing door 15 of the second feeding channel 14 is opened, while the sealing door 15 of the first feeding channel 13 remains closed. The feeding conveyor belt 2 transports several packages sequentially to the preparation conveyor belt 3, and then the sealing door 15 of the second feeding channel 14 is closed. When it is necessary to feed the preparation area 12, the sealing door 15 of the second feeding channel 14 remains closed, while the sealing door 15 of the first feeding channel 13 is opened. The package at the output end of the preparation conveyor belt 3 is transported to the automatic bag-breaking mechanism by the handling mechanism. The package is unpacked by the automatic bag-breaking mechanism, and the material is collected by the collection hopper 4 and transported to the material-using equipment. Then, the preparation conveyor belt 3 transports the next package to the window position near the first feeding channel 13 until all the packages in the preparation area 11 are used up, and then the feeding process for entering the preparation area 11 begins again.

[0032] like Figures 6 to 11 As shown, the conveying mechanism includes a bag positioning frame 5 vertically fixed below the output end of the material preparation conveyor belt 3, and a movable side plate 6 on the bag positioning frame 5 away from the material preparation conveyor belt 3. The bag positioning frame 5 includes a fixed side plate 53, a fixed base plate 54, and two fixed side plates 55. The movable side plate 6 and the bag positioning frame 5 together form a bag positioning chamber for vertically placing a bag inside. The upper side of the bag positioning chamber has an opening that cooperates with the material preparation conveyor belt 3 to allow the bag to slide in. The movable side plate 6 is provided with several pins 7 facing the bag positioning chamber and a pin drive mechanism 8 for driving the pins 7 to move axially back and forth.

[0033] An automatic bag-breaking mechanism is located at the bottom of the bag positioning frame 5; the feeding area 12 is equipped with a side plate transverse movement driver 9 for driving the movable side plate 6 to reciprocate in the direction away from or close to the bag positioning frame 5, and a side plate lifter 18 for driving the movable side plate 6 to rise and fall is also provided between the side plate transverse movement driver 9 and the movable side plate 6.

[0034] During operation, the material bags output from the material conveyor belt 3 fall vertically through the first feeding channel 13 into the material bag positioning chamber formed by the movable side plate 6 and the material bag positioning frame 5. Then, the pin drive mechanism 8 drives the pin 7 to extend and insert it into the top of the material bag, thereby fixing the material bag. Then, the automatic bag breaking mechanism works, making a cut at the bottom of the material bag to allow the contents of the material bag to flow out and be collected by the collection hopper 4. Then, the side plate lifter 18 drives the movable side plate 6 to rise, so that the bottom of the material bag is separated from the bottom of the material bag positioning frame 5. Then, the side plate transverse drive 9 drives the movable side plate 6 to move horizontally away from the material bag positioning frame 5, so that the contents of the material bag can fall directly into the collection hopper 4. The handling mechanism of this application has a simple structure, high efficiency, and low cost. It can be used for both solid and liquid materials. The automatic bag breaking mechanism acts on the end of the material bag, which causes relatively less damage to the material bag itself and can preserve the residual value of the material bag to the greatest extent.

[0035] Furthermore, to facilitate the collection of empty material bags after unpacking, a waste bag collection area 20 is provided next to the feeding area 12 inside the sealed housing 1. The waste bag collection area 20 is located on the side of the sealed housing 1 away from the material preparation conveyor belt 3. The lower part of the side wall of the waste bag collection area 20 is provided with a material bag outlet and a material inlet door 17, and the side plate transverse movement drive 9 is arranged across the top of the feeding area 12 and the waste bag collection area 20.

[0036] Following the above unpacking steps, after unpacking is completed, the side plate transverse drive 9 drives the movable side plate 6 to move above the waste bag collection area 20. Then, the pin drive mechanism 8 controls the pin 7 to retract. After the bag loses the fixation of the pin 7, it automatically falls into the waste bag collection area 20 for collection. Then, the side plate transverse drive 9 can drive the movable side plate 6 to move back to the position that matches the bag positioning frame 5.

[0037] Regarding the specific structure of the automatic bag-breaking mechanism, the automatic bag-breaking mechanism includes a cutter 10 located at the bottom of the bag positioning frame 5 and a cutter driver 16 for driving the cutter 10 to reciprocate along the bottom of the bag positioning frame 5. A driver mounting groove 52 with an upward recess is provided at the bottom of the bag positioning frame 5. The cutter driver 16 is fixedly installed in the driver mounting groove 52. A blade connecting piece 16a with an upward-opening U-shape is connected to the lower end of the driver mounting groove 52. The top of the other end of the blade connecting piece 16a is fixedly connected to the lower root of the cutter 10.

[0038] The fixed base plate 54 of the material bag positioning frame 5 is provided with a blade movement groove 51 that cooperates with the cutter 10. The blade movement groove 51 is positioned above the cutter driver 16, and the blade edge of the cutter 10 extends from the blade movement groove 51 from bottom to top. The cutter driver 16 is placed in the upwardly recessed driver mounting groove 52, which can prevent liquid material from flowing into the cutter driver 16 during unpacking and causing damage, because the liquid will flow downward under the action of gravity and will not flow upward into the driver mounting groove 52.

[0039] The hopper 4 is equipped with several vibrators (not shown in the figure), which can shake solid materials to prevent clogging.

[0040] Both the feeding conveyor belt 2 and the preparation conveyor belt 3 are roller conveyor belts.

[0041] The pin drive mechanism 8, the side plate transverse drive 9, the cutter drive 16, and the door drive mechanism 19 are all powered by electric cylinders or pneumatic cylinders and can be used with guide rails, slide rods and other limiting components.

[0042] The above description is merely a preferred embodiment of the present utility model, showing and describing the basic principles, main features, and advantages of the present utility model. It is not intended to limit the scope of patent protection of the present utility model. Those skilled in the art should understand that the present utility model is not limited to the above embodiments. In addition to the above embodiments, the present utility model may have other implementations without departing from the spirit and scope of the present utility model.
