Description

Technical Field

[0001] This utility model relates to the field of hydraulic mud extruders, specifically a hydraulic mud extruder extrusion device for waterless drilling mud. Background Technology

[0002] Anhydrous taphole clay is mainly used to block the taphole of blast furnaces. It is made by mixing and grinding various corundum, silicon carbide, coke, refractory clay, expanding agent, additives and anhydrous carbonaceous binder. Due to the high hardness and good plasticity of the raw materials of anhydrous taphole clay, the wear resistance requirements of the production and molding equipment of anhydrous taphole clay are high.

[0003] Currently, hydraulic extruders are often used to extrude anhydrous taphole clay during production to shape it. However, existing anhydrous taphole clay extruders are prone to unstable shaping, resulting in cracks on the surface of the output anhydrous taphole clay column, or even breakage of the column, which seriously affects the production quality of the anhydrous taphole clay. Therefore, this paper proposes an extrusion device for anhydrous taphole clay using a hydraulic extruder to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the existing waterless clay extrusion machines are prone to unstable plasticity of the waterless clay during use, resulting in cracks on the surface of the output waterless clay column, or even breakage of the waterless clay column, which seriously affects the production quality of waterless clay. This utility model proposes a hydraulic clay extrusion device for waterless clay.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a hydraulic mud extrusion device for waterless gun mud, including an extrusion tank, a hydraulic cylinder fixedly installed on the top of the extrusion tank, the telescopic end of the hydraulic cylinder passing through the extrusion tank and slidingly connected to the inner cavity of the extrusion tank, a mud plug fixedly connected to the telescopic end of the hydraulic cylinder, positioning rods fixedly connected to both sides of the top of the mud plug, one end of the positioning rod passing through the extrusion tank and slidingly connected to the inner cavity of the extrusion tank, a fixing frame fixedly installed on both sides of the extrusion tank, a support mechanism provided on the surface of the fixing frame, and the support mechanism working in conjunction with the positioning rod and the extrusion tank;

[0006] The support mechanism includes two brackets, which are respectively fixedly installed on the surfaces of two fixed frames. A rotating shaft is rotatably mounted inside the inner cavity of each bracket. A first gear and a second gear are respectively fixedly sleeved on the surfaces of the two rotating shafts. A first toothed plate and a second toothed plate are slidably connected to the surfaces of the two fixed frames. The first toothed plate cooperates with the first gear, and the second toothed plate cooperates with the second gear. A connecting rod is fixedly connected to one side of the first toothed plate, and one end of the connecting rod is fixedly connected to one of the positioning rods. A connecting frame is slidably connected to the top of the second toothed plate, and one end of the connecting frame is fixedly connected to the other positioning rod. A guide groove is formed on the surface of the other fixed frame. A guide rod is fixedly connected to one side of the second toothed plate, and one end of the guide rod is slidably connected inside the guide groove. A steel wire rope is fixedly connected to the surfaces of the two rotating shafts. Several support plates are fixedly sleeved on the surface of the steel wire rope, and these support plates cooperate with the extrusion tank.

[0007] Preferably, a limiting frame is fixedly installed at the bottom of the extrusion tank, and the limiting frame is used in conjunction with the support plate.

[0008] Preferably, positioning blocks are fixedly installed at both ends of the two rotating shafts, and the positioning blocks are rotatably connected inside the bracket.

[0009] Preferably, one of the fixing frames has a connecting groove on its surface, and a connecting block is fixedly installed on the surface of the connecting rod, with the connecting block slidably connected inside the connecting groove.

[0010] Preferably, the bottom of the connecting frame is provided with a sliding groove, and a slider is fixedly installed on the top of the second toothed plate, the slider being slidably connected inside the sliding groove.

[0011] Preferably, a first limiting block is fixedly installed on the surface of the slider, and a first limiting groove is formed in the inner cavity of the slide groove, with the surface of the first limiting block slidably connected to the inner cavity of the first limiting groove.

[0012] Preferably, a second limiting block is fixedly installed at one end of the guide rod, and a second limiting groove is opened in the inner cavity of the guide groove, with the surface of the second limiting block slidably connected to the inner cavity of the second limiting groove.

[0013] Preferably, each of the two fixing frames has a mounting bracket fixedly installed at its bottom, and a guide roller is rotatably installed inside the mounting bracket, the guide roller being used in conjunction with the wire rope.

[0014] The advantages of this utility model are:

[0015] 1. This utility model, by setting up a support mechanism, allows for the temporary sealing of the output port of the extrusion tank during the basic work of anhydrous tapping clay. When the hydraulic cylinder drives the mud plug to extrude the anhydrous tapping clay, the temporary sealing by the support plate makes the anhydrous tapping clay more compact under extrusion. By moving the mud plug, the support plate separates from the output end of the extrusion tank, allowing the anhydrous tapping clay column to be discharged from the output end of the extrusion tank. The next support plate then cuts off the anhydrous tapping clay column to extrude the next column, thus effectively preventing cracks and breaks in the extruded anhydrous tapping clay column that would affect its quality.

[0016] 2. This utility model, by setting guide rods and guide grooves, ensures that when the mud plug moves downwards via the positioning rod, the first toothed plate and the second toothed plate do not contact the second gear. This allows the first toothed plate to drive the first gear to rotate, thereby causing one of the rotating shafts to wind up the wire rope. This allows multiple support plates to intermittently block the output port of the extrusion tank. When the mud plug drives the positioning rod to reset, the second toothed plate contacts the second gear under the guidance of the guide rods and guide grooves, causing another rotating shaft to wind up the wire rope. This allows several support plates to reset when the mud plug resets, so that the next extrusion of anhydrous mud can begin. Attached Figure Description

[0024] 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 scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses an extrusion device for a hydraulic extruder used for waterless tapping clay. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 An extrusion device for a waterless gunning mud hydraulic extruder includes an extrusion tank 1. A hydraulic cylinder 101 is fixedly installed on the top of the extrusion tank 1. The telescopic end of the hydraulic cylinder 101 passes through the extrusion tank 1 and is slidably connected to the inner cavity of the extrusion tank 1. A mud plug 102 is fixedly connected to the telescopic end of the hydraulic cylinder 101. Positioning rods 103 are fixedly connected to both sides of the top of the mud plug 102. One end of the positioning rod 103 passes through the extrusion tank 1 and is slidably connected to the inner cavity of the extrusion tank 1. Fixing frames 2 are fixedly installed on both sides of the extrusion tank 1. A support mechanism 3 is provided on the surface of the fixing frame 2. The support mechanism 3 works in conjunction with the positioning rod 103 and the extrusion tank 1.

[0027] The support mechanism 3 includes two brackets 31, which are fixedly mounted on the surfaces of two fixed frames 2. A rotating shaft 32 is rotatably mounted inside the cavity of each bracket 31. A first gear 33 and a second gear 34 are fixedly sleeved on the surfaces of the two rotating shafts 32, respectively. A first toothed plate 35 and a second toothed plate 36 are slidably connected to the surfaces of the two fixed frames 2, respectively. The first toothed plate 35 cooperates with the first gear 33, and the second toothed plate 36 cooperates with the second gear 34. A connecting rod 3501 is fixedly connected to one side of the first toothed plate 35, and one end of the connecting rod 3501 is connected to one of the... A positioning rod 103 is fixedly connected, and a connecting frame 3601 is slidably connected to the top of the second toothed plate 36. One end of the connecting frame 3601 is fixedly connected to another positioning rod 103. A guide groove 3607 is opened on the surface of another fixed frame 2. A guide rod 3606 is fixedly connected to one side of the second toothed plate 36. One end of the guide rod 3606 is slidably connected to the inside of the guide groove 3607. A steel wire rope 37 is fixedly connected to the surface of the two rotating shafts 32. Several support plates 38 are fixedly sleeved on the surface of the steel wire rope 37. The several support plates 38 are used in conjunction with the extrusion tank 1.

[0028] During the extrusion of anhydrous taphole clay, the anhydrous taphole clay is added to the extrusion tank 1. Then, the hydraulic cylinder 101 drives the plug 102 downward to compress the anhydrous taphole clay. As the plug 102 moves, it drives the positioning rod 103 to move. The positioning rod 103 drives the first toothed plate 35 and the second toothed plate 36 to move downward simultaneously. Guided by the guide rod 3606 and the guide groove 3607, the second toothed plate 36 is prevented from contacting the second gear 34, while the first toothed plate 35 contacts the first gear 33. This causes the first gear 33 to drive one of the rotating shafts 32 to rotate, which in turn winds up the wire rope 37. This causes the wire rope 37 to drive the support plate 38 to move, allowing the support plate 38 to press against the output end of the extrusion tank 1. A brief blockage is performed to make the anhydrous taphole clay more compact under compression. Through the continuous movement of the plug 102, the support plate 38 is separated from the output end of the extrusion tank 1, so that the anhydrous taphole clay column is discharged from the output end of the extrusion tank 1. The anhydrous taphole clay column is then cut off by the next support plate 38 to extrude the next column of anhydrous taphole clay. After one extrusion is completed, the plug 102 resets and drives the positioning rod 103 to reset. During the reset process, the second toothed plate 36 contacts the second gear 34 through the guidance of the guide rod 3606 and the guide groove 3607. The second gear 34 drives another rotating shaft 32 to rotate, so that the other rotating shaft 32 winds up the wire rope 37, so that the wire rope 37 drives several support plates 38 to reset, so that they can be used in the next extrusion of anhydrous taphole clay.

[0029] Reference Figure 1 and Figure 2A limiting frame 104 is fixedly installed at the bottom of the extrusion tank 1. The limiting frame 104 works in conjunction with the support plate 38. The limiting frame 104 can support and limit the support plate 38, preventing the support plate 38 from shifting during the extrusion of the waterless gun clay. At the same time, it can make the support plate 38 stably connected to the output end of the extrusion tank 1.

[0030] Reference Figure 2 Positioning blocks 3201 are fixedly installed at both ends of the two rotating shafts 32, and the positioning blocks 3201 are rotatably connected inside the bracket 31. By installing positioning blocks 3201 at both ends of the rotating shafts 32, the position of the rotating shafts 32 inside the bracket 31 can be stabilized by the positioning blocks 3201, and the rotating shafts 32 can be prevented from becoming loose or falling off.

[0031] Reference Figure 2 One of the fixing frames 2 has a connecting groove 3502 on its surface, and a connecting block 3503 is fixedly installed on the surface of the connecting rod 3501. The connecting block 3503 is slidably connected inside the connecting groove 3502. By sliding the connecting block 3503 inside the connecting groove 3502, the connecting block 3503 and the connecting groove 3502 can stabilize the position of the connecting rod 3501 and the first toothed plate 35, thereby avoiding positional displacement of the first toothed plate 35.

[0032] Reference Figure 3 and Figure 5 The bottom of the connecting frame 3601 is provided with a sliding groove 3602, and the top of the second toothed plate 36 is fixedly installed with a slider 3603, which is slidably connected to the inside of the sliding groove 3602. A first limiting block 3604 is fixedly installed on the surface of the slider 3603, and a first limiting groove 3605 is provided in the inner cavity of the sliding groove 3602. The surface of the first limiting block 3604 is slidably connected to the inner cavity of the first limiting groove 3605. The slider 3603 is slidably connected to the inside of the sliding groove 3602, and the position of the slider 3603 is stabilized by the first limiting block 3604 and the first limiting groove 3605, so as to effectively stabilize the position of the top of the second toothed plate 36 and prevent the second toothed plate 36 from tilting or shifting, so that the second toothed plate 36 can stably perform lateral displacement.

[0033] Reference Figure 3 and Figure 4 A second limiting block 3608 is fixedly installed at one end of the guide rod 3606, and a second limiting groove 3609 is provided in the inner cavity of the guide groove 3607. The surface of the second limiting block 3608 is slidably connected to the inner cavity of the second limiting groove 3609. The slidable connection between the surface of the second limiting block 3608 and the inner cavity of the second limiting groove 3609 stabilizes the position of the guide rod 3606 inside the guide groove 3607 and prevents the guide rod 3606 from separating from the guide groove 3607 and affecting the position of the second toothed plate 36.

[0034] Reference Figure 2 and Figure 3 The bottom of each of the two fixed frames 2 is fixedly installed with a mounting frame 39. A guide roller 3901 is rotatably installed inside the mounting frame 39. The guide roller 3901 is used in conjunction with the wire rope 37. By installing the guide roller 3901 inside the mounting frame 39, the guide roller 3901 supports the wire rope 37, thereby ensuring that the wire rope 37 can drive the support plate 38 to move to a horizontal position.

[0035] Working principle: During the extrusion of anhydrous taphole clay, the anhydrous taphole clay is added to the extrusion tank 1. Then, the hydraulic cylinder 101 drives the plug 102 to move downward, so that the plug 102 compresses the anhydrous taphole clay. When the plug 102 moves, it drives the positioning rod 103 to move. The positioning rod 103 drives the first toothed plate 35 and the second toothed plate 36 to move downward simultaneously. The connecting block 3503 is slidably connected inside the connecting groove 3502 to stabilize the position of the connecting rod 3501 and the first toothed plate 35, so that the connecting rod 3501 drives the first toothed plate 35 to move stably. The second limiting block 3608 and the second limiting groove 3609 stabilize the position of the guide rod 3606, so that the guide rod 3606 and the guide groove 3607 guide the second toothed plate 36. The first limiting block 3604 and the first limiting groove 3605 stabilize the position of the slider 3603 inside the slide groove 3602, so that the connecting frame 3601 stabilizes the position of the top of the second toothed plate 36, so that the second toothed plate 36 does not contact the second gear 34, while the first toothed plate 35 contacts the first gear 33, so that the first gear 33 drives one of the rotating shafts 32 to rotate, and through the positioning block 32 01. Stabilize the position of the rotating shaft 32, causing one of the rotating shafts 32 to wind up the wire rope 37. This wire rope 37 drives the support plate 38 to move, and is guided by the guide roller 3901 in the mounting frame 39. This guides the wire rope 37 to move the support plate 38 to a horizontal position, and simultaneously moves the support plate 38 into the limiting frame 104. The limiting frame 104 stabilizes the position of the support plate 38, allowing it to temporarily block the output end of the extrusion tank 1. This makes the anhydrous mud more compact under extrusion. Through the continuous movement of the mud plug 102, the support plate 38 separates from the output end of the extrusion tank 1, allowing the anhydrous mud to... The water-cooled mud column is discharged from the output end of the extrusion tank 1 and cut off by the next support plate 38 to extrude the next waterless mud column. After one extrusion is completed, the mud plug 102 is reset and drives the positioning rod 103 to reset. During the reset process, the second toothed plate 36 is brought into contact with the second gear 34 by the guide rod 3606 and the guide groove 3607. The second gear 34 drives another rotating shaft 32 to rotate, so that the other rotating shaft 32 winds up the wire rope 37, so that the wire rope 37 drives several support plates 38 to reset, so that they can be used in the next waterless mud extrusion.
