Description

Technical Field

[0001] This utility model relates to the field of mud treatment, and in particular to an oil drilling mud separation and treatment device. Background Technology

[0002] Oil drilling mud is an indispensable key substance in drilling operations. It is mainly composed of water, oil, clay and other chemical additives, and is used to provide necessary support during the drilling process. The main functions of drilling mud include keeping the drill bit cool, removing drill cuttings, balancing downhole pressure, preventing wellbore collapse, and reducing wear on drilling tools. Common types of drilling mud include water-based mud, oil-based mud and synthetic mud, among which water-based mud is the most common because of its lower cost and environmental friendliness.

[0003] The performance of drilling mud directly affects drilling efficiency and safety. Its composition and performance need to be adjusted according to different geological conditions. For example, the viscosity, density and rheological properties of the mud must meet specific requirements to cope with complex drilling environments such as high temperature and high pressure. In addition, additives in the mud can improve its fluidity, drag reduction performance and enhance the effect of preventing wellbore collapse. Therefore, it plays a vital role in oil drilling.

[0004] The drilling mud produced during drilling needs to be separated to separate water from sand and soil. A common separation device is a filter press, which can effectively separate water for recycling or discharge. However, in traditional filter presses, the filter cloth needs to be replaced after a period of use. The traditional replacement and fixing method is to hang the filter cloth in a few pins on the top of the filter plate without a locking mechanism, which makes it easy to fall off during use and affect normal operation. Therefore, an oil drilling mud separation and treatment device is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an oil drilling mud separation and treatment device, which aims to improve the problem that in traditional filter presses, the filter cloth needs to be replaced after a period of use. The traditional replacement and fixing method is to hang the filter cloth in several pins on the top of the filter plate without a locking mechanism, which makes it easy to fall off during use and affect normal operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an oil drilling mud separation and treatment device, including a support frame, a filter press fixedly connected to the top of the support frame, multiple filter plates slidably connected inside the filter press, multiple pins fixedly connected to the top of the filter plates, a discharge port fixedly connected to the bottom of the support frame, a replacement component installed on the top of the filter plates, and an anti-clogging component installed inside the discharge port;

[0007] The replacement component includes a baffle and a housing. The baffle is externally slidably connected between the interior of a plurality of pins. The bottom of the housing is fixedly connected to the top of the filter plate. A spring is fixedly connected to the inner wall of the housing. A sliding plate is fixedly connected to the left end of the spring. A plug is fixedly connected to the left side of the sliding plate. A stop block is slidably connected inside the housing.

[0008] As a further description of the above technical solution:

[0009] The anti-blocking component includes a motor, which is externally fixedly connected to the outside of the discharge port. A rotating rod is fixedly connected to the output end of the motor, and a turntable is fixedly connected to the rear end of the rotating rod. A sliding frame is slidably connected to the rear side of the turntable, and a pressure rod is fixedly connected to the bottom of the sliding frame. A support plate is slidably connected to the outside of the pressure rod.

[0010] As a further description of the above technical solution:

[0011] The external sliding connection of the skateboard is to the inner wall of the housing, and the external sliding connection of the plug rod is to the inside of the housing.

[0012] As a further description of the above technical solution:

[0013] The outside of the insertion rod is inserted into the inside of the baffle, and the outside of the stop block abuts against each other.

[0014] As a further description of the above technical solution:

[0015] The filter press is installed directly above the discharge port, and the filter plates are distributed in a straight line at equal intervals.

[0016] As a further description of the above technical solution:

[0017] The pins are distributed in a straight line at equal intervals.

[0018] As a further description of the above technical solution:

[0019] The front end of the rotating rod is rotatably connected to the inner wall of the discharge port, and the front side of the support plate is fixedly connected to the inner wall of the discharge port.

[0020] As a further description of the above technical solution:

[0021] The rotating rod is externally rotatably connected to the upper side of the support plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by actuating the sliding plate and compressing the spring, the insert rod is retracted into the housing and disengaged from the baffle. At the same time, the stop block will automatically fall down to block the outlet of the insert rod and prevent the insert rod from automatically resetting. Then, the baffle is pulled out from the pin, which realizes the quick replacement and fixation of the filter cloth and prevents the filter cloth from falling off.

[0024] 2. In this utility model, the rotating rod is driven by a motor to rotate, so that the turntable rotates in a uniform manner. Under the limit of the support plate, the sliding frame starts to drive the pressure rod to move up and down synchronously, thereby pushing away the mud and sand blocking the discharge port outlet, thus avoiding blockage and affecting the discharge efficiency.

[0038] Working Principle: When using this device to process sludge, the filter press 2 separates solids and liquids through pressure. During operation, adjacent filter plates 3 and filter cloth are combined to form a filtration chamber. Sludge enters the filtration chamber under the pressure of the pump. Liquid passes through the filter cloth and enters the filter plate 3, exiting through the channel. Solid particles are trapped on the surface of the filter cloth, forming a filter cake as the solids accumulate. When filtration is complete, the filter plate 3 is loosened, the filter cake is removed, and the filter cloth is cleaned, allowing the next filtration cycle to begin. The filter cake falls directly into the discharge port 5, through which the sludge is transported to the bottom of the engineering vehicle's hopper for final removal. When the filter cake falls into the discharge port 5, due to its moisture and strong adhesion, it accumulates in the discharge port 5 and cannot be discharged. At this time, the control motor 12 rotates, causing the rotating rod 13 to drive the turntable 14 to rotate synchronously. Under the support and limit of the support plate 17, the sliding frame 15 drives the pressure rod 16 to reciprocate upwards. The downward movement causes the pressure rod 16 to press, pushing the mud and sand out of the discharge port 5, thus preventing blockage and achieving anti-clogging. After a period of use, the filter cloth needs to be replaced in time if it is damaged. By moving the slide plate 9 to compress the spring 8, the insertion rod 10 is retracted into the housing 7 and disengaged from the baffle 6. At the same time, the stop block 11 will automatically fall down to block the outlet of the insertion rod 10. At this time, the baffle 6 is unlocked. Then, the baffle 6 is pulled out from the pin 4, and the filter cloth is removed from the pin 4. Then, a new filter cloth is placed, and the baffle 6 is passed through the pin 4. Then, the stop block 11 is pulled up to disengage from the insertion rod 10. At this time, the spring 8 will push the slide plate 9 to reset, causing the insertion rod 10 to pop out and insert into the baffle 6, fixing the baffle 6 back onto the filter plate 3, thus blocking the edge of the filter cloth outside the pin 4 and preventing the filter cloth from falling off. The operation is convenient and quick. At this time, the mud separation operation can continue.
