Description

Technical Field

[0001] This utility model relates to the field of mud cake conveying technology, specifically a mud cake conveying device for a mud solid-liquid separator. Background Technology

[0002] Currently, a large amount of drilling mud is generated during natural gas drilling. After treatment, the mud is dehydrated by a solid-liquid separator, typically using a plate and frame filter press. The plate and frame filter press dehydrates the mud to form mud cakes. At this point, a conveying mechanism is needed to transport the mud cakes discharged from the plate and frame filter press to a designated location for centralized processing. Traditionally, belt conveyors are used for this purpose. However, the mud cakes pressed out by the plate and frame filter press have a moisture content of 50-75%, making them highly viscous and prone to sticking to the conveyor surface. As a result, during the conveyor's circulation process, the sticky mud cakes fall to the ground below the conveyor under their own weight, leading to poor mud cake collection and making subsequent cleaning more difficult. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mud cake conveying device for a mud solid-liquid separator, which solves the shortcomings of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: a mud cake conveying device for a mud solid-liquid separator, comprising a belt conveyor and a collection hopper, wherein the belt conveyor is arranged below the mud discharge station of the solid-liquid separator, the collection hopper is arranged below the output end of the belt conveyor, and a scraping mechanism is provided inside the collection hopper, the scraping mechanism comprising an mounting plate and a scraping plate, the mounting plate being connected to the inner wall of the collection hopper, the scraping plate being slidably disposed on the top of the mounting plate, and the end of the scraping plate away from the mounting plate contacting the conveying surface of the belt conveyor.

[0005] Furthermore, the inner wall of the collection hopper is provided with two vertical sliding grooves spaced apart in the horizontal direction, and two screws are provided on the mounting plate. The two screws pass through the two vertical sliding grooves respectively and are threaded with nuts. The heads of the screws press the mounting plate against the collection hopper.

[0006] Furthermore, a strip-shaped groove is provided through the mounting plate, the strip-shaped groove extending along the length of the mounting plate, and the tail of the screw passes through the strip-shaped groove and the vertical groove in sequence to connect to the nut.

[0007] Furthermore, a rectangular groove is provided on the top of the mounting plate, and the end of the scraper away from the belt conveyor is slidably fitted into the rectangular groove.

[0008] Furthermore, a locking screw is threaded onto the mounting plate, a washer is fitted onto the locking screw, the tail of the locking screw passes into a rectangular groove and abuts against the scraper, and the washer is located between the mounting plate and the head of the locking screw.

[0009] Furthermore, baffles are provided on both sides of the conveying surface of the belt conveyor, and the bottom of the baffles is hinged to the conveying frame of the belt conveyor via hinges.

[0010] The beneficial effects of this utility model are:

[0011] By having a scraper contact the conveyor surface below the output end of the belt conveyor, the mud cakes adhering to the belt conveyor are scraped off and fall into the collection hopper, preventing the mud cakes from falling onto the ground below the belt conveyor and causing difficult-to-clean problems. This results in a better centralized collection of mud cakes. Attached Figure Description

[0016] Example 1

[0017] like Figures 1 to 3As shown, a sludge cake conveying device for a sludge solid-liquid separator includes a belt conveyor 1 and a collection hopper 2. The belt conveyor 1 is arranged below the sludge discharge station of the solid-liquid separator, and the collection hopper 2 is located below the output end of the belt conveyor 1. A scraping mechanism is provided inside the collection hopper 2, which includes a mounting plate 3 and a scraper 4. The mounting plate 3 is connected to the inner wall of the collection hopper 2, and the scraper 4 slides through the top of the mounting plate 3. The end of the scraper 4 away from the mounting plate 3 contacts the conveying surface of the belt conveyor 1. The sludge cake formed by dewatering in a plate and frame filter press falls from the bottom of the plate and frame filter press. Below the plate and frame filter press, the belt conveyor 1 is arranged so that the mud cake falls onto the conveying surface of the belt conveyor 1. The belt conveyor 1 transports the mud cake to the collection hopper 2, where it is concentrated and piled up. Then, an excavator loads the mud cake from the collection hopper 2 onto a truck and transports it to a designated site for further processing. During the cyclic conveying process, the belt conveyor 1 will come into contact with the scraper plate 4, which scrapes off the mud cake adhering to the belt conveyor 1, preventing the mud cake from falling onto the ground below the belt conveyor and causing difficult-to-clean problems. This results in a better centralized collection effect of the mud cake.

[0018] Example 2

[0019] Based on Embodiment 1, baffles 11 are provided on both sides of the conveying surface of the belt conveyor 1. The bottom of the baffles 11 is hinged to the conveying frame of the belt conveyor 1 by a hinge. The baffles 11 prevent mud cakes from falling to the ground from both sides of the belt conveyor 1.

[0020] Example 3

[0021] Based on Example 2, such as Figures 1 to 3 As shown, the inner wall of the collecting hopper 2 is provided with two vertical grooves 5 spaced horizontally. Two screws 6 are threaded through the mounting plate 3, passing through the two vertical grooves 5 respectively, and are threaded with nuts 7. The heads of the screws 6 press the mounting plate 3 against the collecting hopper 2. A strip groove 8 is provided through the mounting plate 3, extending along the length of the mounting plate 3. The tails of the screws 6 pass through the strip groove 8 and the vertical grooves 5 in sequence, connecting to the nuts 7. Because the ground at the drilling site is uneven, the belt conveyor 1 and the collecting hopper 2 are... The difficulty in installing bucket 2 horizontally means that scraper 4 cannot properly fit the conveying surface of belt conveyor 1, resulting in areas that are missed during scraping. Therefore, mounting plate 3 is pressed and installed on collecting bucket 2 by screw 6 and nut 7. The vertical slide 5 can be used to adjust the installation height of mounting plate 3, and the strip slide 8 allows mounting plate 3 to be installed at an angle, so that scraper 4 can adapt to the inclination angle of the conveying surface of belt conveyor 1 and can contact the conveying surface of belt conveyor 1 to complete the scraping operation.

[0022] Example 4

[0023] Based on Example 3, such as Figure 2 and Figure 3 As shown, a rectangular groove is provided on the top of the mounting plate 3. The end of the scraper plate 4 away from the belt conveyor 1 is slidably fitted into the rectangular groove. A locking screw 9 is threaded onto the mounting plate 3. A washer 10 is fitted onto the locking screw 9. The tail of the locking screw 9 passes into the rectangular groove and presses against the scraper plate 4. The washer 10 is located between the mounting plate 3 and the head of the locking screw 9, which can adjust the extension length of the scraper plate 4, increase the range of action of the scraping mechanism, and enable the scraper plate 4 to fit against the conveying surface of the belt conveyor 1 for scraping operation. Specifically, loosen the locking screw 9, move the scraper plate 4 to fit against the conveying surface of the belt conveyor 1, and finally tighten the locking screw 9. The operation is simple and quick.
