Description

A rock cuttings material processing device Technical Field

[0001] This utility model relates to the field of rock cuttings processing technology, specifically to a rock cuttings material processing device. Background Technology

[0002] During oil drilling or natural gas exploration, rock fragments broken up by the drill bit at the bottom of the well are continuously returned to the surface with the circulation of drilling fluid, forming rock cuttings. Since the rock cuttings contain many uncertain hazardous substances, most of the rock cuttings are buried on site. With the flow of groundwater, the harmful substances in the rock cuttings will pollute the groundwater, so they need to be treated.

[0003] However, existing rock cuttings processing equipment cannot separate rock cuttings into particles during use, thus affecting the efficiency of rock cuttings cleaning.

[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN210033381U discloses a rock cuttings processing system, comprising a conveyor belt feeder, a mixing host, and a conveyor belt output machine arranged sequentially from front to back. The output end of the conveyor belt feeder is located above the feed inlet of the mixing host, and the discharge outlet of the mixing host is located above the front end of the conveyor belt output machine. The mixing host includes a mixing frame and a mixing chamber connected to the mixing frame. The top of the mixing chamber is provided with a rock cuttings inlet and a powder inlet. Two parallel mixing shafts are also installed inside the mixing chamber, and the mixing shafts are connected to a stirring rod. The mixing shaft has multiple stirring blades arranged in a spiral, with the width direction of the stirring blades forming an acute angle with the axis of the stirring shaft. A discharge port is located on one side of the bottom of the mixing chamber, corresponding to the front end of the conveyor belt output machine. Above the conveyor belt feeder, from front to back, are arranged a rock cuttings screening machine that can quantitatively output rock cuttings and a disinfectant additive machine that can quantitatively output disinfectant. On one side of the mixing host, there is at least one powder additive machine that can quantitatively add curing agent into the mixing host. It can treat rock cuttings by adding disinfectant and curing agent, and has the advantages of compact and reasonable structure, good treatment effect and effective environmental protection.

[0005] The aforementioned device uses stirring blades to agitate rock cuttings during operation, which facilitates uniform mixing of the rock cuttings. However, the screening efficiency of the rock cuttings processing system in the aforementioned device is low, which affects the efficiency of separating the rock cuttings mixture and thus reduces the processing efficiency of the equipment. Summary of the Invention

[0006] The purpose of this invention is to provide a rock cuttings material processing device to solve the problem of low screening efficiency in the rock cuttings processing system mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rock cuttings material processing device, including a screen frame, with a collection bin fixedly installed on the bottom surface of the screen frame. According to the process flow, the device comprises a feeder, a screening mechanism, a belt conveyor, a mixing bin, a reagent storage tank, and a conveyor. The upper part of the screening mechanism is the screen frame, and the lower structure includes a chain conveyor. The screen frame and the chain conveyor are connected via the collection bin. The screening mechanism also includes a support frame and a drive mechanism. Both the screen frame and the chain conveyor are driven by a transmission structure. A belt conveyor is installed below the chain conveyor, with the end of the belt conveyor extending into the material inlet. The material inlet is fixedly installed on the outer surface of the mixing chamber; the length of the belt conveyor is greater than that of the chain conveyor, and the chain conveyor is included in the vertical projection. The belt conveyor is used to receive the material on the chain conveyor, and the end of the belt conveyor extends into the material inlet of the mixing chamber; the agent inlet installed above the mixing chamber is connected to multiple agent storage tanks through a spiral weighing and metering device, and a material outlet is provided at the bottom of the end of the mixing chamber, with a conveyor installed below the material outlet; the metering device is located at the bottom of the agent storage tank, and a breather valve is provided on the top of the agent storage tank, with the exhaust port of the breather valve connected to a dust collector.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The material is transported to the screening mechanism by the set feeding machine and poured onto the screen frame. The screen frame can screen out large block and strip-shaped materials. Through the operation of the screen frame, they can be collected in one place. The material falling from the gap of the screen rod of the screen frame is received by the chain plate of the chain plate conveyor. The material passes through the screen frame and the collection bin in sequence to the chain plate of the chain plate conveyor. Through operation, the material is conveyed to the belt conveyor, thus ensuring efficient processing of rock cuttings. In order to improve the processing efficiency and fully realize automated operation, the feeding machine adopts an automatic feeding system. The shovel shovels in a certain amount of material, which is then shoveled onto the conveying mechanism by the slag removal arm. The conveying mechanism then transports the material to the screening mechanism for subsequent process flow. The automatic feeding system has multiple omnidirectional wheels on both sides of its bottom for easy movement and direction adjustment. The shovel and scraper arm can be made of carbon steel with rust and corrosion protection treatment, or PE or PP materials. When using PE or PP materials, a reinforcement layer is required at the connection with the hydraulic system to improve the power of the scraper arm. The shovel is also inclined to facilitate material scooping. For special materials, such as drilling cuttings, which have uneven particle size distribution, irregular shape, complex composition, and poor flowability after adsorbing drilling fluid, continuous operation cannot be guaranteed when using automatic feeding. Therefore, a loader can be used as the feeding machine. The capacity is selectable, and the power is large enough to meet production needs.

[0016] (2) The belt conveyor is longer than the chain plate conveyor and is used to receive the materials on the entire chain plate conveyor. In particular, the front end of the belt conveyor can receive the materials thrown out by the chain plate conveyor due to inertia. If necessary, a tarpaulin is set at the front end of the chain plate conveyor to prevent materials with high moisture content from splashing and polluting the surrounding environment of the work area.

[0017] (3) The servo motor drives the belt one to drive the screen frame to run in cycles. The reinforcing plate is welded on the running part of the screen frame. The reinforcing plate drives multiple screen rods to screen. The screen rods are generally made of round profiles. The diameter of the screen rods is generally 3-5cm to meet certain strength requirements. The two ends of the screen rods are welded together with the reinforcing plate. The reinforcing plate is linked with the running part of the transmission component. The screen rods can be oil rods used in the oil extraction process. The stepper motor drives the belt two to drive the chain plate conveyor to improve the transmission efficiency. The chain plate conveyor is composed of multiple carbon steel plates and can withstand the impact of materials falling from a height.

[0018] (4) The end of the belt conveyor extends into the material inlet of the mixing chamber. A reduction motor is installed directly below the belt conveyor to drive the mixing roller 1. The mixing roller 2 is rotated by the reduction motor 2. The blades on the mixing shaft are spiral. During the mixing process, the material is pushed forward by the spiral blades. The agent is fully mixed with the material in the mixing chamber through the agent inlet. The material falling from the material outlet is received by the conveyor and transported to the designated position. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-3. This utility model provides the following technical solution: A rock cuttings material processing device includes a screen frame 1, with a collection bin 2 fixedly installed on the bottom surface of the screen frame 1. According to the process flow, the components are, in sequence, a feeding machine, a screening mechanism, a belt conveyor, a mixing bin 13, a reagent storage tank, and a conveyor. The upper part of the screening mechanism is the screen frame 1, and the lower structure includes a chain conveyor 12. The screen frame 1 and the chain conveyor 12 are connected through the collection bin 2. The screening mechanism also includes a support frame 3 and a drive mechanism. Both the screen frame 1 and the chain conveyor 12 are driven by a transmission structure. A belt conveyor is installed below the chain conveyor 12, with the end of the belt conveyor extending into the material inlet. 14, and the material inlet 14 is fixedly installed on the outer surface of the mixing chamber 13; the length of the belt conveyor is greater than the length of the chain conveyor 12, and the chain conveyor 12 is included in the vertical projection. The belt conveyor is used to receive the material on the chain conveyor 12, and the end of the belt conveyor extends into the material inlet of the mixing chamber 13; the agent inlet 15 installed above the mixing chamber 13 is connected to multiple agent storage tanks through a spiral weighing and metering device, and the bottom end of the mixing chamber 13 is provided with a material outlet 20, and a conveyor is provided below the material outlet 20; the metering device is set at the bottom of the agent storage tank, and the top of the agent storage tank is provided with a breather valve, and the exhaust port of the breather valve is connected to the dust collector.

[0028] The material is transported to the screening mechanism by a feeding machine and poured onto the screen frame 1. The screen frame 1 can screen out large block and strip-shaped materials. Through the operation of the screen frame 1, the materials can be collected in one place. The material falling from the gaps of the screen rods 8 of the screen frame 1 is received by the chain plates of the chain conveyor 12. The material passes through the screen frame 1 and the collection bin 2 in sequence to the chain plates of the chain conveyor 12. Through operation, the material is conveyed to the belt conveyor, thereby improving the efficiency of rock cutting screening. The chain plates are overlapped and made of carbon steel. The carbon steel plates have a certain strength and rigidity, which can effectively buffer potential energy. In order to improve the processing efficiency and fully realize automated operation, the feeding machine adopts an automatic feeding system. The shovel scoops in a certain amount of material, and then the slag-removing arm controlled by the hydraulic system scoops it onto the conveying mechanism, which then conveys it to the screening mechanism for subsequent processing. The process involves an automatic feeding system with multiple omnidirectional wheels on both sides of the bottom for easy movement and direction adjustment. The shovel and scraper arm can be made of carbon steel with rust and corrosion protection, or PE or PP materials. When using PE or PP, a reinforcing layer is required at the connection point with the hydraulic system to improve the scraper arm's power. The shovel is angled to facilitate material scooping; the upper surface is sloped with an angle or gradient of 5-30°, while the side away from the conveying mechanism is thinner. The bottom surface of the shovel is parallel to the conveying mechanism. The scraper arm is installed vertically, with its long side aligned with the length of the shovel. The conveying mechanism is connected to the screening mechanism. The horizontal opening angle of the scraper arm is 0-180°, with a length of 300-500mm, a height of 150-200mm, and a thickness of 10-20mm. A magnetic separator is installed after the feeder or on the side of the belt conveyor near the mixing chamber 13. The magnetic separator is suspended 20cm above the belt conveyor via a pergola and is used to remove iron objects from the material to protect the mixing blades and mixing shaft inside the mixing chamber 13. The magnetic separator can be a permanent magnet magnetic separator to adsorb iron objects. After power failure, it is easy to collect iron objects in a unified manner. The mixing blades are selected from ceramic materials according to the characteristics of the material to make full use of their wear resistance and reduce the frequency of replacement of mixing blades; or carbon steel materials can be selected and their surfaces are treated with anti-corrosion and anti-rust treatment.

[0029] A baffle is installed on the inner side of the screen frame 1 and above the screen rod 8 to prevent material from splashing into the transmission mechanism and affecting its normal operation.

[0030] Example 2: Based on Example 1, please refer to Figures 1-4. A screen rod 8 is also disclosed, and its specific structure is as follows: A servo motor 4 is fixedly installed on the outer surface of the screen frame 1. An output shaft 5 is rotatably installed at the output end of the servo motor 4. A belt 6 is rotatably installed on the outer surface of the output shaft 5. The screen frame 1 includes parallel reinforced welding plates 7 and multiple screen rods 8. The two ends of the screen rods 8 are welded to the reinforced welding plates 7. The reinforcing welding plates 7 and the moving parts of the belt 6 are connected by welding or by high-strength bolts. The chain conveyor 12 is also ensured to operate periodically by a stepper motor 9, a rotating shaft 10, a belt, etc.

[0031] Furthermore, the belt conveyor is longer than the chain conveyor 12, used to receive materials on the entire chain conveyor 12. In particular, the front end of the belt conveyor can receive materials thrown out by the chain conveyor 12 due to inertia. If necessary, a tarpaulin can be installed at the front end of the chain conveyor 12 to prevent materials with high moisture content from splashing and polluting the surrounding environment of the work area. To speed up the processing, multiple screening mechanisms can be connected in series. Accordingly, the length of the belt conveyor is extended. The servo motor 4 drives the rotating parts of the belt 6 to move the welded reinforcing plate 7. The reinforcing plate 7 drives multiple screen rods 8 for screening. The screen rods 8 are generally made of round profiles with a diameter of [missing information]. The screen rod is typically 3-5cm long, meeting certain strength requirements. Both ends of the screen rod 8 are welded to the reinforcing welded plate 7, and the reinforcing welded plate 7 is linked to the moving parts of the transmission components. The stepper motor 9 drives the belt 11 to drive the chain conveyor 12, thereby improving the transmission efficiency. The screen rod 8 can be made of oil rods used in oil extraction, which can meet the requirements of strength and rigidity, and can also be reused. For special materials, such as drilling cuttings, which have characteristics such as uneven particle size distribution, irregular shape, complex composition, and poor fluidity after surface adsorption of drilling fluid, continuous operation cannot be guaranteed when using automatic feeding. Therefore, a loader can be used as the feeding machine, with selectable capacity and high power to meet production needs.

[0032] Example 3: Based on Example 1, please refer to Figures 2-6. A stirring roller 17 is also disclosed, the specific structure of which is as follows: Multiple agent inlets 15 are provided at the upper part of the stirring chamber 13.

A stirring roller 17 is rotatably installed at the output end of the geared motor 16. A geared motor 28 is rotatably installed on the outer surface of the stirring chamber 13. A stirring roller 29 is rotatably installed on the outer surface of the geared motor 2. A stepper motor 9 is fixedly installed on the outer surface of the collection chamber 2. A rotating shaft 10 is rotatably installed on the output shaft of the stepper motor 9. A belt 21 is rotatably installed on the outer surface of the rotating shaft 10.

[0033] The tail section of the belt conveyor is generally inclined upwards, with the end extending into the material inlet 14 of the mixing chamber 13. Directly below the belt conveyor is a geared motor 16 that drives the mixing roller 17. Two sets of agitators can be set side by side. The length of the mixing shaft is determined according to the length of the mixing chamber 13. The mixing roller 19 is driven to rotate by the geared motor 18. The blades on the mixing shaft are spiral. During the mixing process, the material is pushed forward by the spiral blades. The mixing blades are configured to fit the mixing chamber 13. Multiple chemical inlets 15 are provided at the upper part of the mixing chamber 13. The chemicals are thoroughly mixed with the materials inside the mixing chamber 13 through the chemical inlets 15. The material outlet 20 is located at the bottom of the mixing chamber 13, away from the material inlets 14. The materials falling from the material outlet 20 are caught by a conveyor and transported to a designated location. Depending on the characteristics of the work area, the conveyor can be switched in direction at certain locations. The material inlets 14 and chemical inlets 15 are generally protruding parts of the mixing chamber 13, or located at the upper part of the mixing chamber 13. The corresponding components are fitted with appropriate notches. A spiral weighing device is installed at the bottom of the chemical storage tank. The addition ratio of the chemical is controlled by the spiral weighing scale. A breather valve is installed on the top of the tank to ensure pressure balance within the tank when powdery chemicals are pumped in. The exhaust port of the breather valve is connected to a dust collector. For powdery chemicals, dust is generated during entry into the tank; the dust collector effectively suppresses dust leakage and ensures hygiene in the work area. An air pump is installed at the bottom of the chemical storage tank, or a hoist is installed on the outside of the tank. Powdered chemicals can enter the chemical storage tank in two ways: one is by unloading the chemical into a collection silo and then lifting it to the top of the tank using a hoist before unloading it into the storage tank; the other is by pumping the chemical into the storage tank using an air pump. A shock absorption system is installed at the bottom of the mixing chamber 13 to protect the equipment, reduce mechanical damage, and enhance equipment stability.
