Description

Technical Field

[0001] The present invention relates to the technical field of three-lobe screw rotors, and particularly to an impact-resistant three-lobe screw rotor. Background Art

[0002] The Depam rotor pump is a positive displacement pump with low speed, high lift and high efficiency. The working principle of the rotor pump is to suck the liquid from the suction port of the pump through the rotation of the rotor, and then push the liquid to the outlet of the pump, so as to achieve the purpose of transportation. The structural design of the three-lobe screw rotor enables it to work in low-speed and high-viscosity liquids, and can also transport liquids containing solid particles or fibers.

[0003] In the prior art, as disclosed in Chinese Patent No.: CN104929978B, a novel impact-resistant molecular pump rotor includes a rotor main body. An impeller with multiple leaf teeth is arranged on the outer surface of its upper part, and multiple spiral grooves are dug on the outer surface of its lower part. The impeller on the upper part of the rotor main body is divided into three layers by a first isolation groove and a second isolation groove. From top to bottom, they are the first blade, the second blade and the third blade. The number of leaf teeth of the third blade is even and twice the number of spiral grooves. Every other leaf tooth of the third blade is connected to the groove wall of the multiple spiral grooves. This structure not only reduces the processing of segmented leaf teeth, eliminates the moving isolation ring, simplifies the structure of the molecular pump, but also greatly strengthens the strength of the leaf teeth and improves the impact resistance of the leaf teeth.

[0004] However, in the prior art, two spiral cam rotors that continuously rotate driven by a synchronous gear push the medium from the inlet of the pump to the outlet of the pump, thus completing the transportation. Due to the perfect sealing between the rotor and the pump body, the inlet and outlet chambers of the pump are completely separated, and it has a strong vacuum suction capacity. However, most of the existing rotors are straight two-lobe rotors or straight three-lobe rotors, with large pulsations and large pulses generated when transporting materials, resulting in low working efficiency.

[0005] Therefore, we propose an impact-resistant three-lobe screw rotor to solve the problems raised above. Summary of the Invention

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 - 11, the present invention provides a technical solution: an impact-resistant three-leaf spiral rotor, comprising: a spiral rotor assembly 2, there are two spiral rotor assemblies 2, both of the two spiral rotor assemblies 2 include a three-leaf spiral rotor body 201, two isolation grooves 205 are respectively opened on the outer surface of the two three-leaf spiral rotor bodies 201 near the top, a spiral groove 207 is opened on the outer surface of the two three-leaf spiral rotor bodies 201 near the bottom, movable grooves 208 are respectively opened on the opposite sides of the spiral groove 207, and a rotating hole 202 is opened on one side of each of the two three-leaf spiral rotor bodies 201; a restoring assembly 4, there are two restoring assemblies 4, the two restoring assemblies 4 are respectively arranged inside the two isolation grooves 205, both of the two restoring assemblies 4 include movable baffles 401, a plurality of fixing rods 404 are fixedly installed on the tops of the two movable baffles 401, sliders 407 are fixedly installed at one ends of the plurality of fixing rods 404, and fixing springs 406 are arranged on the outer surfaces of the plurality of fixing rods 404 near one end; a closing assembly 5, the closing assembly 5 is arranged between the inner walls of the two movable grooves 208, the closing assembly 5 includes a support rod 501 and a sliding rod 504, a plurality of closing doors 502 are installed between the opposite sides of the support rod 501 and the sliding rod 504, two buckle blocks 503 are fixedly installed on the opposite outer surfaces of the plurality of closing doors 502, and adjacent two buckle blocks 503 are slidably buckled together. When in use, the two threaded interfaces 103 are threadedly connected to an external pipeline. After the material is conveyed from one of the connecting pipes 102 into the pump chamber body 101, through the rotation transmission of the two spiral rotor assemblies 2, it is output from the other threaded interface 103. The rotating holes 202 of the two spiral rotor assemblies 2 are slidably connected to the rotating pipe 303 correspondingly, and then the threaded cover 306 is screwed onto the two threaded blocks 305 to prevent the two spiral rotor assemblies 2 from falling off during rotation. Through the two isolation grooves 205, the upper half of the three-leaf spiral rotor body 201 can be divided into three parts, the upper two parts are of the same size, and the lowermost part is the largest. And the lowermost part is provided with the spiral groove 207. Then when the two three-leaf spiral rotor bodies 201 rotate to convey the material, the openings of the two isolation grooves 205 and the spiral groove 207 both have the function of attracting air flow, which can assist in reducing the pulse generated when the three-leaf spiral rotor body 201 conveys the material, and solves the problem that most of the existing rotors are straight two-leaf rotors or straight three-leaf rotors, resulting in a large pulse during material conveyance and easily leading to low work efficiency. Usually, when the straight-tooth cam rotates 60 degrees, the material only enters less than 1 / 5. When the spiral cam rotates 60 degrees, the material enters more than 2 / 5. When the straight-tooth cam rotates 120 degrees, the material only enters less than 1 / 2. When the spiral cam rotates 120 degrees, the material enters more than 2 / 4. When the straight-tooth cam rotates 180 degrees, the material only enters less than 3 / 4. When the spiral cam rotates 180 degrees, the material has been completely discharged from the cavity. Therefore, the spiral rotor reduces the rotational speed compared to the straight-tooth rotor, speeds up the material conveyance, and completely eliminates the pulse problem.Compared with the straight tooth efficiency, the efficiency is increased by more than 25%. In addition, when the isolation slot 205 needs to be closed, the movable baffle 401 is pulled out of the slide slot 206 by pulling down, until the locking block 602 is stuck in the locking slot 403. When the isolation slot 205 is unfolded, the auxiliary block 603 is pressed outward, so that the auxiliary block 603 drives the reinforcing block 601 to pull the locking block 602 out of the locking slot 403. Under the rebound effect of multiple fixed springs 406, the movable baffle 401 can be embedded in the slide slot 206. When the spiral slot 207 is closed, the movable baffle 401 is pulled out of the slide slot 206. When it is necessary to close, the multiple closing doors 502 are unfolded by pulling the sliding rod 504. The multiple closing doors 502 and the multiple buckle blocks 503 are only in contact and not fixed. The horizontal and vertical positions can be moved. The adjacent buckle blocks 503 are locked and limited with each other. The sliding rod 504 will drive the closing doors 502 and the buckle blocks 503 to slide in the movable groove 208, thereby closing the spiral groove 207. The three-leaf spiral rotor 101 is restored by closing the isolation groove 205 and the spiral groove 207, so that the three-leaf spiral rotor 101 has a variety of uses.

[0036] like Figure 8 , Figure 9 and Figure 11 As shown, the three side outer surfaces of the two movable baffles 401 are fixedly installed with shift blocks 402, the other three side outer surfaces of the two movable baffles 401 are provided with locking grooves 403, the inner walls of one side of the two isolation grooves 205 are provided with sliding grooves 206, the inner walls of the two sliding grooves 206 are provided with multiple positioning grooves 209, and the inner walls of the multiple positioning grooves 209 are fixedly installed with retaining rings 405. By shifting the shift blocks 402, the movable baffles 401 can be easily slid out of the sliding grooves 206, and the retaining rings 405 can prevent the fixed springs 406 from sliding out of the positioning grooves 209.

[0037] like Figure 11 As shown, the outer surfaces of the multiple sliders 407 are respectively slidably connected to the inner walls of the multiple positioning grooves 209, and one ends of the multiple fixing rods 404 slide through the outside of the multiple retaining rings 405. The sliding of the sliders 407 in the positioning grooves 209 can realize the sliding of the fixing rods 404.

[0038] like Figure 11 As shown, one end of the plurality of fixed springs 406 is fixedly connected to the outer surfaces of the plurality of sliders 407 , respectively, and the other end of the plurality of fixed springs 406 is fixedly connected to the outer surfaces of the plurality of retaining rings 405 , respectively, and the connection of the fixed springs 406 is achieved through the sliders 407 and the retaining rings 405 .

[0039] like Figures 8 - 9As shown, on the inner walls of the other sides of the two isolation grooves 205, a plurality of engaging components 6 are fixedly installed. Each of the plurality of engaging components 6 includes a reinforcing block 601. Through the engaging action of the engaging components 6, the position of the restoring component 4 is limited to prevent rebound.

[0040] As Figure 8 shown, on one side of each of the plurality of reinforcing blocks 601, a locking block 602 is fixedly installed. On the other side of each of the plurality of reinforcing blocks 601, an auxiliary block 603 is fixedly installed. The outer surfaces of the plurality of locking blocks 602 are respectively engaged with the inner walls of the plurality of locking grooves 403. The locking block 602 and the corresponding locking groove 403 are matched, and when inserted, it can prevent the movable baffle 401 from detaching.

[0041] As Figure 1 、 Figure 2 and Figure 5 shown, on the inner walls of the two rotating holes 202, limiting grooves 203 are opened. At both ends of the two rotating holes 202, rotating grooves 204 are opened. On the inner walls of the two rotating grooves 204, positioning components 3 are slidably connected. Through the opening of the rotating grooves 204, the fixing plate 301 and the threaded cover 306 can both rotate within the rotating groove 204, achieving a hidden effect.

[0042] As Figure 2 and Figure 10 shown, each of the two positioning components 3 includes a rotating tube 303. On the outer surfaces of the two rotating tubes 303, limiting blocks 304 are fixedly connected. The outer surfaces of the two limiting blocks 304 are respectively slidably connected with the inner walls of the two limiting grooves 203. In the inner walls of the two rotating tubes 303, rotating rods 302 are movably connected. By inserting the limiting blocks 304 into the limiting grooves 203, when the rotating tube 303 rotates around the rotating rod 302, the three - lobe rotor body 201 can be driven to rotate simultaneously.

[0043] As Figure 1 、 Figure 2 and Figure 10 shown, at one end of each of the two rotating rods 302, a fixing plate 301 is fixed. At the other end of each of the two rotating rods 302, a threaded block 305 is fixed. At one end of each of the two threaded blocks 305, a threaded cover 306 is threadedly sleeved. Outside the two screw rotor assemblies 2, a pump chamber assembly 1 is provided. The threaded block 305 facilitates the installation of the threaded cover 306, and is convenient for the disassembly and installation of the three - lobe rotor body 201.

[0044] As Figure 1 、 Figure 2 and Figure 10As shown, the pump chamber assembly 1 includes a pump chamber body 101. Connecting pipes 102 are fixedly connected and communicated to the opposite sides of the pump chamber body 101. Threaded interfaces 103 are fixedly connected to one ends of the two connecting pipes 102. The outer surfaces of the two fixing plates 301 are fixedly connected to the inner wall of the pump chamber body 101. The pump chamber body 101 can be connected to an external pipeline through the threaded interfaces 103, thereby realizing material transportation.

[0045] Usage method and working principle of this device: When in use, two threaded interfaces 103 are threadedly connected to external pipelines. After the material is conveyed from one connecting pipe 102 into the interior of the pump chamber body 101, through the rotational transmission of two spiral rotor assemblies 2, it is output from the other threaded interface 103. The rotating holes 202 of the two spiral rotor assemblies 2 are slidably connected to the rotating pipe 303 correspondingly, and then the threaded cover 306 is screwed onto the two threaded blocks 305 to prevent the two spiral rotor assemblies 2 from falling off during rotation. Through the two isolation grooves 205, the upper half of the three-lobe spiral rotor body 201 can be divided into three parts. The upper two parts are of the same size, and the bottom part is the largest. And the bottom part is provided with a spiral groove 207. Then when the two three-lobe spiral rotor bodies 201 rotate to convey materials, the openings of the two isolation grooves 205 and the spiral groove 207 both have the function of attracting air flow, which can assist in reducing the pulse generated when the three-lobe spiral rotor body 201 conveys materials, solving the problem that most existing rotors are straight two-lobe rotors or straight three-lobe rotors, resulting in a relatively large pulse during material conveyance and prone to low work efficiency. Usually, when the straight-tooth cam rotates 60 degrees, the material only enters less than 1 / 5. When the spiral cam rotates 60 degrees, the material enters more than 2 / 5. When the straight-tooth cam rotates 120 degrees, the material only enters less than 1 / 2. When the spiral cam rotates 120 degrees, the material enters more than 2 / 4. When the straight-tooth cam rotates 180 degrees, the material only enters less than 3 / 4. When the spiral cam rotates 180 degrees, the material has been completely discharged from the cavity. Therefore, the spiral rotor reduces the rotational speed compared to the straight-tooth rotor, speeds up the material conveyance, completely eliminates the pulse problem, and increases the efficiency by more than 25% compared to the straight-tooth rotor. In addition, when the isolation groove 205 needs to be closed, by pulling down the movable baffle 401, the movable baffle 401 is pulled out from the sliding groove 206 until the locking block 602 is locked into the locking groove 403. When the isolation groove 205 is unfolded, by pressing the auxiliary block 603 outwards, the auxiliary block 603 drives the reinforcing block 601 to pull the locking block 602 out of the locking groove 403. Under the resilient action of multiple fixing springs 406, the movable baffle 401 can be embedded into the sliding groove 206. When the spiral groove 207 needs to be closed, by pulling the sliding rod 504, multiple closing doors 502 are unfolded. There is only contact between the multiple closing doors 502 and the multiple buckling blocks 503, and they are not fixed. Their horizontal and vertical positions can move. The adjacent buckling blocks 503 are buckled and limited to each other. The sliding rod 504 drives the closing doors 502 and the buckling blocks 503 to slide in the movable groove 208, thereby closing the spiral groove 207. By closing the isolation groove 205 and the spiral groove 207, the three-lobe spiral rotor 101 is restored, making the three-lobe spiral rotor 101 have usage diversity.
