Description

Technical Field

[0001] The utility model relates to the technical field of screw pump production, in particular to a screw pump stator steam drying box. Background Art

[0002] The screw pump is a single screw transport pump. Its main working parts are the eccentric spiral screw (called rotor) and the screw bushing (called stator) with a double-line spiral surface on the inner surface. Its working principle is that when the motor drives the pump shaft to rotate, the screw rotates around its own axis on the one hand, and rolls along the inner surface of the bushing on the other hand, thus forming a sealed chamber of the pump. During the manufacturing process of the stator of the screw pump, it is necessary to use a sprayer to sandblast and shot blast its inner wall. After spraying, in order to speed up the air drying speed, a steam drying box is usually used to dry the stator. The steam drying box mainly transfers heat to the drying box through a steam boiler. In order to achieve uniform heating of the stator, the driving device is used to drive the stator to roll in the drying box, so that the steam drying box can achieve the purpose of quickly drying the stator. However, after the stator is dried, the worker needs to manually remove the stator from the drying box. The method of removing the stator in such a high temperature environment is relatively complicated and it is easy to cause burns to the worker. To this end, we provide a screw pump stator steam drying box to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0014] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0015] The utility model proposes a screw pump stator steam drying box, including a box body 1, a heat transfer component is arranged in the box body 1, and the heat transfer component can transfer heat to the box body 1 by connecting with a steam boiler. The inner cavity of the box body 1 is concentrically provided with two in-line active rollers 2 along the length direction, and the inner cavity of the box body 1 is provided with a driven roller 3 on the parallel side of the active roller 2. The active roller 2 and the driven roller 3 are both rotatably connected to the bottom of the inner cavity of the box body 1 through a bearing mounting seat. The active roller 2 is controlled to rotate by a driving component. The operation of the driving component can drive the active roller 2 to rotate, and then drive the active roller 2 and the driven roller 3 to rotate. The stator rotates between the rollers 3, and a bracket 11 is arranged between the active roller 2 and the driven roller 3 along the length direction. When the stator contacts the active roller 2 and the driven roller 3, the bracket 11 can be separated from the stator, thereby preventing the bracket 11 from affecting the rotation of the stator. The bracket 11 is controlled to rise and fall by a cylinder 12, and the cylinder 12 is fixedly arranged at the bottom of the box 1. The cylinder 12 can provide power for the lifting and lowering of the bracket 11 as a power source, so that the dried stator can leave the high-temperature area inside the box 1, and the staff can pull the stator to remove it by wearing gloves and other protective gear, thereby ensuring the safety of the staff.

[0016] Specifically, the bracket 11 is configured as a plate-like structure, the top of the bracket 11 is designed to be concave inwardly curved, and a plurality of grooves 13 are provided on the inner arc surface of the top of the bracket 11, and balls 14 are provided in the grooves 13. By providing the grooves 13 at the top of the bracket 11 and providing the balls 14 in the grooves 13, the stator can slide on the bracket 11 under the dragging action of an external force, thereby reducing the labor intensity of the staff.

[0017] Specifically, slide bars 15 are fixedly provided on both sides of the bottom of the bracket 11, and the outer wall of the slide bar 15 is provided with a slide sleeve 16, which is fixedly installed in the interior of the box body 1 in a through-type manner. Through the cooperation of the slide bar 15 and the slide sleeve 16, the movement of the bracket 11 can be limited, thereby ensuring the stability of the bracket 11 when supporting the stator.

[0018] Specifically, the heat transfer component includes an air inlet pipe 6, a coil 7, an exhaust pipe 8 and a drain pipe 9. The air inlet pipe 6 is fixedly arranged on the outer wall of the box body 1. The air inlet pipe 6 is fixedly connected to the coil 7. The coil 7 is coiled in the inner cavity of the box body 1, located below the active roller 2 and the driven roller 3, and fixed by a fixing frame. The coil 7 is connected to the steam boiler through the air inlet pipe 6, so that the steam with heat can transfer heat at the coil 7. The other end of the coil 7 is fixedly connected to the exhaust pipe 8. The exhaust pipe 8 is connected with a drain pipe 9. The exhaust pipe 8 and the drain pipe 9 both penetrate the outer wall of the box body 1. After the steam is absorbed, the internal gas will be discharged at the exhaust pipe 8. The exhaust pipe is connected to the drain pipe 9 through a drain valve. The drain valve is closed when encountering gas. When the water vapor condenses into water, the floating valve inside floats up and opens the valve to discharge the water. After the water is discharged, the floating valve is closed again, thereby realizing the discharge of steam condensate.

[0019] Specifically, the driving assembly includes a driving device 5 and a connecting shaft 4. The two active rollers 2 are connected to each other in synchronous rotation through the connecting shaft 4. The output end of the driving device 5 is fixedly connected to the connecting shaft 4. The driving device 5 actually includes a motor as a power source. The motor is connected to the turbine reducer through a belt groove pulley to reduce the output speed, and is connected to the connecting shaft 4 through another set of belt groove pulleys, so that the motor drives the active roller 2 to rotate through the connecting shaft 4.

[0020] Specifically, a purification pipe 10 is connected to one side of the top of the box 1, and the other end of the purification pipe 10 is connected to the purifier. The purifier is arranged outdoors. The purifier can absorb and purify the gas generated when the inside of the box 1 is dried through the purification pipe 10. A mounting frame 17 is fixedly arranged between the bottom of the box 1 and the cylinder 12, and the mounting frame 17 can support the cylinder 12.

[0021] According to the personnel in this field, all the electrical parts and components in this case are universal standard parts or components known to the technical personnel in this field, and their structures and principles can be known to the technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All the electrical parts in this case are connected to the power supply adapted to them through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0022] Working principle: When using the steam drying box, first, after the screw pump stator is sandblasted and shot blasted, it is placed between the active roller 2 and the driven roller 3, and the box cover on the top of the box body 1 is closed. At this time, the heat transfer component and the driving device 5 are started. The driving device 5 drives the active roller 2 to rotate through the connecting shaft 4, and then drives the stator to rotate. At this time, the coil 7 can bring steam through the steam boiler connected to the air inlet pipe 6. The steam transfers heat to the box body 1 through the coil 7. When the stator rotates, it is heated, which can achieve uniform drying of the stator. After drying, the box cover of the box body 1 is opened, and the cylinder 12 drives the bracket 11 to move up until the bracket 11 and the stator are located above the outside of the box body 1. At this time, the stator leaves the high-temperature area inside the box body 1. The staff can pull the stator by wearing gloves and other protective gear to make the stator slide on the top of the ball 14, which reduces the labor intensity of the staff and makes the entire process of removing the stator more convenient and safe.
