Description

Technical Field

[0001] The present invention relates to the technical field of vane pumps, and specifically to a vane pump for transporting viscous materials. Background Art

[0002] A vane pump is a positive-displacement pump that realizes liquid transportation through the relative movement of a rotor and vanes. Its core components include a rotor, a stator, vanes, and a distributor plate; the rotor is eccentrically installed inside the stator, and the vanes can slide freely in the rotor slots. When the rotor rotates, the vanes are pressed against the inner wall of the stator under the action of centrifugal force or hydraulic pressure, forming multiple sealed working chambers.

[0003] After the vane pump transports viscous materials, viscous materials are likely to remain on its inner wall, making it inconvenient to effectively clean. After drying, it will cause blockage of the inner wall of the vane pump, affecting its subsequent normal use; at the same time, after the existing vane pump is used, due to the poor ventilation efficiency at its inner wall, moisture is likely to corrode the inner wall of the vane pump during long-term storage. Summary of the Invention

[0004] The technical problems solved by this solution are as follows:

[0005] (1) How to solve the problem that viscous materials are likely to remain on the inner wall of the vane pump, making it inconvenient to effectively clean, and after drying, it causes blockage of the inner wall of the vane pump, affecting its subsequent normal use;

[0006] (2) How to solve the problem that due to the poor ventilation efficiency at the inner wall of the vane pump, moisture is likely to corrode the inner wall of the vane pump during long-term storage.

[0007] The object of the present invention can be achieved by the following technical solutions: A vane pump for transporting viscous materials, including a base and a housing fixedly installed on its top. A vane pump body is arranged inside the housing. A cleaning mechanism for cleaning residual viscous materials inside it is arranged on one side of the vane pump body, and an air-drying mechanism for drying the vane pump body is arranged on the top inner wall of the housing.

[0008] The cleaning mechanism includes a sealed box slidably connected to the base through a guide rail. A connecting sleeve is communicated with the side of the sealed box facing the vane pump body. A sealing ring is arranged on the inner wall of the connecting sleeve, and the position of the connecting sleeve corresponds to the position of the input end of the vane pump body.

[0009] A further technical improvement of the present invention lies in that: A transversely arranged adjusting cylinder is fixedly installed on the inner wall of the housing. A piston is slidably arranged inside the adjusting cylinder. A cross bar is fixedly connected to the side of the piston. One end of the cross bar movably penetrates through the adjusting cylinder and is fixedly installed with a first shift lever.

[0010] A further technical improvement of the present invention lies in that: a horizontally arranged first cylinder is fixedly installed on the side wall of the outer shell, the extending end of the first cylinder is fixedly connected to the sealing box, and a second dial rod is fixedly installed at the extending end of the first cylinder. The top of the sealing box is communicated with a liquid outlet pipe, and the input end of the liquid outlet pipe is communicated with the end of the adjusting cylinder close to the first cylinder.

[0011] A further technical improvement of the present invention lies in that: a turning frame is rotatably arranged on the inner wall of the outer shell. One end of the turning frame is movably connected to the first dial rod, and the other end of the turning frame is slidably connected to the second dial rod. A tension spring is fixedly connected between the inner wall of the outer shell and the middle part of the turning frame close to the first dial rod.

[0012] A further technical improvement of the present invention lies in that: a liquid storage tank is fixedly installed on the inner wall of the outer shell. The liquid storage tank is filled with a sufficient amount of cleaning agent, and the bottom of the liquid storage tank is communicated with a connecting pipe. The output end of the connecting pipe is communicated with the end of the adjusting cylinder far from the first cylinder. By controlling the extending end of the first cylinder to extend from the shortest to the longest, the sealing box and the connecting sleeve are driven to move. The connecting sleeve sleeves the input end of the vane pump body. At the same time, due to the pulling force of the tension spring, the turning frame will pull the piston to move. When the piston slides to the end of the adjusting cylinder close to the first cylinder, at this time, the cleaning agent enters the sealing box. Then, the vane pump body is started, so that after the cleaning agent enters the vane pump body, it carries the residual viscous material and discharges it from its output end, completing the cleaning of the inner wall of the vane pump body, avoiding blockage caused by the drying of the viscous material, and preventing the subsequent normal use of the vane pump body from being affected.

[0013] A further technical improvement of the present invention lies in that: the air drying mechanism includes a first guide frame and a second guide frame fixedly connected to the inner wall of the outer shell. An L-shaped square tube is jointly and movably inserted inside the first guide frame and the second guide frame. A jet pipe is communicated with the middle part of the L-shaped square tube, and the output end of the jet pipe faces the vane pump body.

[0014] A further technical improvement of the present invention lies in that: a second cylinder is fixedly installed on the top of the outer shell. The second cylinder is longitudinally arranged, and an electric heating rod is fixedly installed at the extending end of the second cylinder. The bottom end of the electric heating rod movably penetrates into the top of the L-shaped square tube. A baffle is fixedly installed in the upper middle part of the L-shaped square tube, and a thrust spring is elastically arranged between the baffle and the second guide frame.

[0015] A further technical improvement of the present invention lies in that: a blower is fixedly arranged on the inner wall of the housing. The output end of the blower is communicated with the top side of the L-shaped square pipe through an air inlet pipe, and a rubber plate is arranged below the blower. The output ends of the air spraying pipe and the L-shaped square pipe correspond to the position of the rubber plate. By controlling the extension end of the second cylinder to extend to the longest, during this process, the electric heating rod extends into the interior of the L-shaped square pipe. At the same time, the extension end of the second cylinder provides a pressing force on the top of the L-shaped square pipe, so that the output end of the L-shaped square pipe faces the input end of the vane pump body, while the output end of the air spraying pipe is blocked by the rubber plate. The electric heating rod is turned on, so that the air flow entering the L-shaped square pipe is heated and then blown out from the output end of the L-shaped square pipe. The inner wall of the vane pump body is quickly dried by the hot air flow, avoiding the corrosion of the inner wall caused by moisture during the long-term storage of the vane pump body.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] When the present invention is in use, by controlling the extension end of the first cylinder to extend from the shortest to the longest, the sealing box and the connecting sleeve are driven to move. The connecting sleeve sleeves the input end of the vane pump body. At the same time, due to the pulling force of the tension spring, the turning frame will pull the piston to move. When the piston slides to the end of the adjusting cylinder close to the first cylinder, at this time, the cleaning agent enters the sealing box. Then, the vane pump body is started, so that after the cleaning agent enters the vane pump body, it carries the residual viscous material and discharges from its output end, completing the cleaning of the inner wall of the vane pump body, avoiding the blockage caused by the drying of the viscous material and preventing the subsequent normal use of the vane pump body from being affected.

[0018] When the present invention is in use, by controlling the extension end of the second cylinder to extend to the longest, during this process, the electric heating rod extends into the interior of the L-shaped square pipe. At the same time, the extension end of the second cylinder provides a pressing force on the top of the L-shaped square pipe, so that the output end of the L-shaped square pipe faces the input end of the vane pump body, while the output end of the air spraying pipe is blocked by the rubber plate. The electric heating rod is turned on, so that the air flow entering the L-shaped square pipe is heated and then blown out from the output end of the L-shaped square pipe. The inner wall of the vane pump body is quickly dried by the hot air flow, avoiding the corrosion of the inner wall caused by moisture during the long-term storage of the vane pump body.

[0029] Please refer to Figure 2 and Figure 3 As shown, the above-mentioned cleaning mechanism 9 includes a sealing box 905 slidably connected to the base 3 through a guide rail. A connecting sleeve 904 is communicated with the side of the sealing box 905 facing the vane pump body 7. A sealing ring is arranged on the inner wall of the connecting sleeve 904, and the position of the connecting sleeve 904 corresponds to the position of the input end of the vane pump body 7.

[0030] Please refer to Figure 3 and Figure 4As shown, a regulating cylinder 909 is fixedly installed on the inner wall of the above-mentioned outer shell 5 in a horizontal direction. A piston 902 is slidably arranged on the inner wall of the regulating cylinder 909. A cross bar 908 is fixedly connected to the side surface of the piston 902. One end of the cross bar 908 movably penetrates through the regulating cylinder 909 and is fixedly installed with a first shifting lever 911.

[0031] Please refer to Figure 2 and Figure 3 As shown, a first air cylinder 4 is fixedly installed on the side wall of the above-mentioned outer shell 5 in a horizontal direction.

[0032] Please refer to Figure 3 and Figure 4 As shown, a turning frame 910 is rotatably arranged on the inner wall of the above-mentioned outer shell 5. One end of the turning frame 910 is movably connected to the first shifting lever 911, and the other end of the turning frame 910 is slidably connected to the second shifting lever 906. A tension spring 907 is fixedly connected between the inner wall of the outer shell 5 and the middle part of the turning frame 910 close to the first shifting lever 911.

[0033] Please refer to Figure 2 and Figure 4 As shown, a liquid storage tank 10 is fixedly installed on the inner wall of the above-mentioned outer shell 5. The liquid storage tank 10 is filled with a sufficient amount of cleaning agent, and a connecting pipe 901 communicates with the bottom of the liquid storage tank 10. The output end of the connecting pipe 901 communicates with the end of the regulating cylinder 909 far from the first air cylinder 4; by controlling the extending end of the first air cylinder 4 to extend from the shortest to the longest, the sealing box 905 and the connecting sleeve 904 are driven to move, and the connecting sleeve 904 sleevs the input end of the vane pump body 7. At the same time, due to the pulling force of the tension spring 907, the turning frame 910 will pull the piston 902 to move. When the piston 902 slides to the end of the regulating cylinder 909 close to the first air cylinder 4, at this time, the cleaning agent enters the sealing box 905. Then, the vane pump body 7 is started, so that after the cleaning agent enters the vane pump body 7, it carries the residual viscous material and discharges from its output end, completing the cleaning of the inner wall of the vane pump body 7, avoiding the blockage caused by the drying of the viscous material, and preventing the subsequent normal use of the vane pump body 7 from being affected.

[0034] Please refer to Figure 2 and Figure 5 As shown, the above-mentioned air drying mechanism 6 includes a first guiding frame 605 and a second guiding frame 606 fixedly connected to the inner wall of the outer shell 5. An L-shaped square pipe 607 is jointly and movably inserted into the inside of the first guiding frame 605 and the second guiding frame 606. A jet pipe 603 communicates with the middle part of the L-shaped square pipe 607. The output end of the jet pipe 603 faces the vane pump body 7.

[0035] Please refer to Figure 5 and Figure 6 As shown, a second cylinder 1 is fixedly installed at the top of the above-mentioned outer shell 5. The second cylinder 1 is longitudinally arranged, and an electric heating rod 608 is fixedly installed at the extending end of the second cylinder 1. The bottom end of the electric heating rod 608 movably penetrates into the top of the L-shaped square tube 607. A baffle 602 is fixedly installed in the upper middle part of the L-shaped square tube 607. A thrust spring is elastically arranged between the baffle 602 and the second guide frame 606.

[0036] Please refer to Figure 2 and Figure 5 As shown, a blower 2 is fixedly arranged on the inner wall of the above-mentioned outer shell 5. The output end of the blower 2 is communicated with the top of the side surface of the L-shaped square tube 607 through an air inlet pipe 601. A rubber plate 604 is arranged below the blower 2. The positions of the air spray pipe 603 and the output end of the L-shaped square tube 607 correspond to that of the rubber plate 604. By controlling the extending end of the second cylinder 1 to extend to the longest, during this process, the electric heating rod 608 extends into the interior of the L-shaped square tube 607. At the same time, the extending end of the second cylinder 1 provides a pressing force on the top of the L-shaped square tube 607, so that the output end of the L-shaped square tube 607 faces the input end of the vane pump body 7, while the output end of the air spray pipe 603 is blocked by the rubber plate 604. The electric heating rod 608 is turned on, so that the air flow entering the L-shaped square tube 607 is heated and then blown out from the output end of the L-shaped square tube 607. The inner wall of the vane pump body 7 is quickly dried by the hot air flow, avoiding the corrosion of the inner wall caused by moisture during the long-term storage of the vane pump body 7.

[0037] Please refer to Figure 2 As shown, a perforation 8 for placing an external feed pipe is provided on the back of the above-mentioned outer shell 5.

[0038] Working principle: When the present invention is in use, first, as Figure 1 and Figure 2 shown, after the transportation of the viscous material is completed, the external feed pipe is removed from the input end of the vane pump body 7 and then pulled out from the perforation 8; as Figure 3 and Figure 4 shown, by controlling the extending end of the first cylinder 4 to extend from the shortest to the longest, the sealing box 905 and the connecting sleeve 904 are driven to move, so that the connecting sleeve 904 sleeves the input end of the vane pump body 7. At the same time, due to the pulling force of the tension spring 907, the turning frame 910 will pull the cross bar 908 and the piston 902 to move. When the piston 902 slides to the end of the adjusting cylinder 909 close to the first cylinder 4, at this time, as Figure 2 and Figure 3As shown, the cleaning agent in the liquid storage tank 10 will enter the sealing box 905 along the connecting pipe 901, the regulating cylinder 909 and the liquid outlet pipe 903. Then, start the vane pump body 7, so that after the cleaning agent enters the vane pump body 7, it carries the remaining viscous material and discharges from its output end, completing the cleaning of the inner wall of the vane pump body 7, avoiding blockage of the vane pump body 7 caused by the drying of the viscous material, and preventing the subsequent normal use of the vane pump body 7 from being affected; As Figure 4 and Figure 5 shown, during the process of the vane pump body 7 transporting viscous material, the extending end of the second cylinder 1 is in the shortest state. Through the action of the thrust spring, the output end of the L-shaped square pipe 607 is blocked by the bottom side of the rubber plate 604, as Figure 2 and Figure 5 shown, by turning on the blower 2, since the electric heating rod 608 blocks the top of the L-shaped square pipe 607, the air flow sprays out from the output end of the air jet pipe 603, facilitating the air cooling and heat dissipation of the vane pump body 7 operating at high power; As Figure 2 、 Figure 5 and Figure 6 shown, after cleaning the inner wall of the vane pump body 7, promptly control the extending end of the first cylinder 4 to reset and contract to the shortest, and control the extending end of the second cylinder 1 to extend to the longest. During this process, the electric heating rod 608 extends into the interior of the L-shaped square pipe 607. At the same time, as Figure 5 and Figure 6 shown, through the extending end of the second cylinder 1 providing pressure to the top of the L-shaped square pipe 607, the output end of the L-shaped square pipe 607 faces the input end of the vane pump body 7, while the output end of the air jet pipe 603 is blocked by the top side of the rubber plate 604. Turn on the electric heating rod 608, so that the air flow entering the L-shaped square pipe 607 is heated and then blows out from the output end of the L-shaped square pipe 607. The inner wall of the vane pump body 7 is quickly dried by the hot air flow, avoiding corrosion of the inner wall caused by moisture during the long-term storage of the vane pump body 7.

Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to form equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention.
