Description

Technical Field

[0001] This invention relates to the field of engineering machinery, and more specifically, to a clay suction device and its working method. Background Technology

[0002] Pneumatic conveying is an important means of transporting powders, lumps, and non-Newtonian fluids. It uses airflow as the conveying medium to transport materials from one or more sources to one or more destinations.

[0003] In recent years, my country has experienced frequent geological disasters such as landslides and mudslides. When people are buried under mud and require rescue, the use of conventional rescue machinery such as excavators and loaders can easily cause secondary injuries to the buried individuals. In such cases, pneumatic conveying equipment can be used for mud suction, achieving non-mechanical contact and non-destructive removal, thus improving rescue efficiency and safety. At the same time, municipal pipelines, rivers, ponds, and other waterways are prone to silt accumulation due to their slow flow rate, requiring regular dredging and cleaning. Pneumatic conveying equipment can also be used for silt removal operations.

[0004] However, in southern regions prone to landslides and mudslides, rescue operations often encounter sites with water-laden, cohesive soil. This type of soil is highly viscous, making it difficult to separate soil clumps during suction operations, leading to difficulties in suction. Large clumps of soil can easily clog suction pipes during transport, severely reducing suction efficiency and impacting rescue speed. The cohesive soil can also easily block the suction head, causing excessive negative pressure within the pipes, which can collapse the pipes and damage the blower. Similarly, this type of viscous silt is also encountered during the dredging of municipal pipelines, rivers, and ponds, resulting in difficulties in suction and easy pipe blockage. Summary of the Invention

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Combination Figures 1 to 3As shown, the clay suction device in this embodiment includes a suction section 1, a material taking section 2, and a pushing section 3. The suction section 1 includes a suction pipe 11 and a dividing member 12 disposed at the inlet end of the suction pipe 11. The material taking section 2 is disposed at the inlet end of the suction section 1 and includes a scraping blade 22 for scraping the clay to be suctioned. The pushing section 3 is configured to push the clay to be scraped off by the scraping blade 22 towards the dividing member 12 to divide the clay.

[0052] In this embodiment, the scraper blade 22 can scrape the clay off, and the clay can be divided by the dividing component 12 under the pressure of the pushing part 3. This improves the problem in the prior art that large pieces of soil are not easy to peel off and are easy to block the suction pipe during the conveying process, which seriously reduces the suction efficiency and affects the rescue speed.

[0053] like Figure 1 , 2 As shown in Figure 5, the material handling unit 2 also includes a scraping blade 22 located outside the feed inlet 23. The scraping blade 22 is connected to the feed pipe 21 at one end of the feed inlet 23 along the circumference of the feed pipe 21 and extends to the other end of the feed inlet 23. The distance between the scraping blade 22 and the feed inlet 23 gradually increases towards the other end. One end of the scraping blade 22 is a fixed end connected to the suction pipe 11, and the other end is a free end that is raised relative to the suction pipe 11. As the scraping blade 22 rotates with the feed pipe 21, it can scrape off the clay to be suctioned. The scraped clay is guided by the scraping blade 22 into the interior of the feed pipe 21. When the feed inlet 23 rotates to the closed position of the sealing component 5, the feed pipe 21 is closed, and the clay, after being divided, can flow along the suction pipe 11 under negative pressure.

[0054] The dividing component 12 includes an intercepting component disposed in the suction pipe 11 and multiple channels disposed on the intercepting component for the flow of the divided clay. Specifically, the dividing component 12 may be composed of multiple tubular components parallel to the suction pipe 11. The clay is dispersedly entered into the multiple tubular components under the pressure of the pushing part, thereby dividing the clay.

[0055] The material handling unit 2 also includes a feed pipe 21 rotatably sleeved on the inlet end of the suction pipe 11. A feed inlet 23 is provided on the circumferential surface of the feed pipe 21. A sealing member 5 is connected to the suction pipe 11. The sealing member 5 is configured to close the feed inlet 23 after the feed inlet 23 is rotated to the position of the sealing member 5.

[0056] In some embodiments, the sealing component 5 includes a semi-circular tube disposed at the inlet end of the suction tube 11. Optionally, the sealing component 5 is integrally disposed with the suction tube 11.

[0057] like Figure 4As shown, the suction tube 11 has a semi-circular front end and a cylindrical rear end. The dividing tube 12 is located inside the cylindrical rear end of the suction tube 11. Three air inlets are located at the rear end of the suction tube 11, distributed on the upper part and left and right sides. The dividing tube 12 is composed of seven small-diameter tubes and is installed inside the cylindrical section of the suction tube 11, flush with the transition surface between the cylindrical and semi-circular sections. The length L1 of the cylindrical rear end of the suction tube 11 is greater than the length L2 of the semi-circular front end. The length L3 of the dividing tube is greater than the length L5 of the feed inlet and less than 2 / 3 of the length L1 of the cylindrical rear end. The distance L4 between the air inlets and the transition surface between the cylindrical and semi-circular sections is greater than the length L3 of the dividing tube. There are three air inlets; the opening diameter Ф2 should be greater than 1 / 3 of the diameter Ф1 of the suction tube and less than 1 / 2 of the diameter Ф1.

[0058] In this embodiment, the length L3 of the dividing component 12 is greater than the length L5 of the feed inlet, so the clay block with a size equivalent to the length of the feed inlet 23 can be divided. The length L3 of the dividing component 12 is not greater than 2 / 3 of the length of the suction tube 11, which helps to prevent the divided clay from clumping again during the flow in the suction tube 11.

[0059] The material handling unit 2 consists of a material collecting pipe 21 and a scraper blade 22. The material collecting pipe 21 is provided with a feed inlet, and the scraper blade 22 is installed at the feed inlet. The scraper blade 22 is arc-shaped, and the opening direction is consistent with the rotation direction of the material handling unit. The length L6 of the material collecting pipe 21 is equal to the length L2 of the semi-circular pipe at the front end of the suction pipe 11, and the length L5 of the feed inlet is greater than 1 / 2 of the length L6 of the material collecting pipe.

[0060] like Figure 6 As shown, the pressing part 3 includes a piston 33 and a first driving component 32. The piston 33 is movably disposed in the feed pipe 21; one end of the first driving component 32 is connected to the feed pipe 21, and the other end is connected to the piston 33. In some embodiments, the first driving component 32 includes a hydraulic cylinder.

[0061] In some embodiments, the pressing part 3 further includes a mounting base 31 disposed in the feed pipe 21 and connected to the inner wall of the feed pipe 21, and the first driving component 32 is mounted on the mounting base 31.

[0062] Mounting base 31 includes a plurality of rod-shaped members extending radially along feed pipe 21, the plurality of rod-shaped members being arranged radially. One end of each rod-shaped member is connected to the inner wall of feed pipe 21, and the other end is connected to first drive member 32.

[0063] In some embodiments, the suction pipe 11 is provided with an air inlet 13, which is located downstream of the dividing member 12 in the direction of clay flow. The clay suction device also includes an air intake regulating device 4 for controlling the opening and closing and / or the opening degree of the air inlet 13.

[0064] When the pressing part 3 pushes the clay to the inlet of the dividing part 12, the inlet of the dividing part 12 is blocked. In order to prevent the negative pressure in the suction pipe 11 from being too large and damaging the blower or suction pipe, the air intake regulating device 4 can open the air valve 43 at this time. After the clay is divided by the dividing part 12, the air valve 43 is closed, and the divided clay can flow along the suction pipe under negative pressure.

[0065] In some embodiments, the intake regulating device 4 includes a second driving component 41, a transmission mechanism 42, and a valve 43. The second driving component 41 is connected to the suction tube 11; the transmission mechanism 42 is drivenly connected to the second driving component 41; and the valve 43 is connected to the transmission mechanism 42 to control the opening and closing of the intake port 13 and / or adjust the opening degree under the drive of the second driving component 41.

[0066] Optionally, the second drive component 41 includes a hydraulic cylinder.

[0067] In some embodiments, the transmission mechanism 42 includes a support member 423, a slide rail 422, and a wedge block 421. The support member 423 is connected to the valve 43; the slide rail 422 is configured to guide the movement of the support member 423; the wedge block 421 is connected to a second drive member 41 and configured to move along a direction intersecting the slide rail 421 under the drive of the second drive member 41, the wedge block 421 including a pressing ramp inclined relative to the extending direction of the slide rail 422, the pressing ramp abutting against the support member 423 so that the pressing ramp pushes the support member 423 along the slide rail 421 during the movement of the wedge block 421 under the drive of the second drive member 41.

[0068] The slide 422 extends radially along the suction tube 11; the wedge block 421 is configured to move in a direction parallel to the axial direction of the suction tube 11 under the drive of the second drive member 41.

[0069] Combination Figure 2 and 7As shown, the intake regulating device 4 consists of a first driving component 41, a transmission mechanism 42, and a valve 43. It is installed on the cylindrical pipe at the rear end of the suction pipe 11, and the opening and closing of the intake port can be controlled by the valve 43. The first driving component 41 is connected to the transmission mechanism 42, and the transmission mechanism 42 is connected to the valve 43, which can drive the valve 43 to rise and fall. The transmission mechanism 42 consists of a wedge block 421, a slide rail 422, and a support component 423. The tail of the wedge block 421 is installed on the first driving component 41, and the head is nested inside the slide rail 422, sliding along the outer wall of the suction pipe 11. The slide rail 422 is installed on the outer wall of the suction pipe 11. The support component 423 is a U-shaped rod, with one end nested inside the slide rail 422 and the valve 43 installed at the other end. The diameter Ф3 of the valve 43 is larger than the diameter Ф2 of the intake port opening. The arc surface of the valve 43 can seal tightly against the outer wall of the suction pipe 11 where the intake port is located, and can completely cover the intake port.

[0070] According to another aspect of the present invention, a method for operating a clay suction device is also provided, the method comprising:

[0071] Close the aforementioned air inlet 13;

[0072] The scraper blade 22 of the material handling section 2 rotates to scrape the clay;

[0073] The material handling section 2 rotates until the inlet 23 is closed by the sealing component 5 and then stops rotating;

[0074] Open the aforementioned air inlet 13;

[0075] The pressing part 3 pushes the clay scraped off by the scraping blade 22 into the dividing part 12 and presses it in;

[0076] Close the air inlet 13 to use the negative pressure in the suction pipe 11 to suction the separated clay.

[0077] In some embodiments, the air inlet 13 is opened before the scraping blade scrapes the clay.

[0078] like Figure 8 As shown, specifically, when the clay suction device is working, it is connected to the suction truck via a pipeline. Before the suction operation begins, the air vent 13 is opened and the feeding piston 33 is retracted. The suction method is as follows:

[0079] (1) After the suction operation is started, the first drive component 41 of the air intake regulating device 4 retracts, and the valve 43 closes the air intake hole under the action of gravity and negative pressure.

[0080] (2) The material taking part 2 rotates, and the scraper blade 22 peels off the large pieces of clay from the body during the rotation process. The clay is then sucked into the collecting pipe 21 by gravity and negative pressure of the pipe.

[0081] (3) When the feed inlet of the collecting pipe 21 is rotated to coincide with the semi-circular pipe at the front end of the suction pipe 11, the collecting pipe 21 stops rotating, and a sealed space is formed inside the collecting pipe 21. Then the air intake regulating device 4 opens the air intake hole.

[0082] (4) The feeding piston 33 pushes the large piece of clay into the dividing tube 12, dividing the clay into multiple small pieces, and then the feeding piston 33 retracts.

[0083] (5) The air inlet is closed, and the divided clay is sucked away under negative pressure. At the same time, the material taking part 2 rotates and enters the next material taking cycle.

[0084] The technical advantages of the clay suction device in this embodiment are as follows:

[0085] (1) The clay suction device can quickly peel off the body of the clay to be suctioned by rotating the scraper blade. The clay enters the collection pipe under the action of gravity and negative pressure of the pipeline, thereby improving the suction efficiency of the clay.

[0086] (2) The suction device can use the feeding piston to press the clay inside the collection pipe into the dividing pipe, divide the large clay into small pieces and then suction it, reducing the risk of the clay blocking the conveying pipe.

[0087] (3) By cooperating with the material taking part and the feeding piston, the air intake regulating device controls the opening and closing of the air intake hole to prevent the negative pressure in the pipeline from being too large and damaging the blower or crushing the suction pipeline after the suction device is blocked.

[0088] The above are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
