Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning pipelines of containers with liquid or liquid under pressure, and specifically relates to a device for quickly cleaning inlets and outlets of containers with liquid or pressure (barrels, tanks, and jars) after the outlets or liquid outlets are blocked when the containers are liquid or under pressure. Background Art

[0002] In the industrial production process, barrels, tanks, and other containers used for storage, transfer of solutions or reactions usually have a discharge pipe at the bottom, which is connected to a delivery pump or delivery pipe to transport the materials in the container. Due to the crystallization of materials or precipitation of solid phase in the container, the discharge pipe may be blocked, affecting the normal transportation of materials in the container, and the discharge pipe needs to be cleaned in time.

[0003] At present, in order to clean the discharge pipe, it is necessary to first drain the material in the container and release the pressure before cleaning, which has a great impact on normal production, and the material in the container is usually discharged through the discharge pipe: when the discharge pipe is not completely blocked, the discharge speed is low; when the discharge pipe is completely blocked, it is impossible to discharge the material first and then clean it. Usually, the discharge pipe needs to be disassembled at the flange and then cleaned. During the cleaning process, it is difficult to avoid that a large amount of material in the container is discharged through the discharge pipe that has just been cleaned, which poses a great safety hazard and is difficult to recover the discharged material.

[0004] Moreover, the materials used in industrial production are mostly acidic, alkaline or corrosive. With the current cleaning methods, it is difficult to avoid contact with the materials during cleaning operations, further increasing the safety risks of the cleaning operations. Summary of the invention

[0005] In order to overcome the problems existing in the background technology, the utility model provides a device for cleaning a discharge pipe of a pressurized or liquid-carrying container. By providing a cleaning tool connected to the discharge pipe through a flange blind plate, the outlet pipe can be cleaned without discharging the material in the container, thereby improving the cleaning efficiency and avoiding the safety operation risks associated with discharging the material in the container.

[0020] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0021] In the description of the present invention, unless otherwise specified, the terms "inside", "outside", etc., indicating the orientation or state relationship, are based on the orientation or state relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "provided with" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention will be understood according to specific circumstances.

[0023] like Figure 1-2 As shown, the device for cleaning the discharge pipe of a pressurized or liquid-carrying container comprises a container body 5, a discharge pipe 6 and a cleaning tool. The container is a reaction, transfer or storage container such as a tank, a can or a barrel.

[0024] The discharge pipe 6 is arranged at the lower part of the container body 5. A valve 9 is arranged on the discharge pipe 6. The valve 9 is connected to a conveying pump or a conveying pipe and other equipment. When the valve 9 is opened, the material in the container body 5 is conveyed through the conveying pump or the conveying pipe.

[0025] The cleaning tool comprises a flange blind plate 1, a screw rod 2, a handle 4 and a spiral piece 3. A threaded hole matching the screw rod 2 is provided at the center of the flange blind plate 1, and the screw rod 2 passes through the threaded hole and is threadedly connected to the flange blind plate 1. A handle 4 is provided at the outer end (outside the discharge pipe 6) of the screw rod 2, and a spiral piece 3 is provided at the inner end (inside the discharge pipe 6), and a cone head 7 is provided at the inner end. The discharge pipe 6 is arranged horizontally, and the flange blind plate 1 is flange-connected to the discharge pipe 6. After the connection, the screw rod 2 is parallel to the discharge pipe 6 and is located at the center of the discharge pipe 6. The screw rod 2 is rotated by operating the handle 4. When the screw rod 2 rotates, the cone head 7 and the spiral piece 3 clean the crystals or precipitates in the discharge pipe 6.

[0026] The screw rod 2 is a full-thread screw rod and is always threadedly connected with the flange blind plate 1 during the rotation process.

[0027] As a preferred solution, a sealing gasket 8 is provided on the inner end face of the handle 4, and a sealing gasket 8 is provided on the outer end face of the flange blind plate 1, and the sealing gaskets 8 on the handle 4 and the flange blind plate 1 are directly opposite. The cleaning tool can be always set in the discharge pipe 6, and when cleaning is not needed or finished, the handle 4 is rotated to squeeze and fit the sealing gasket 8 on the inner end of the handle with the sealing gasket 8 between the flange blind plate 1 to form a seal, thereby preventing the material from leaking out of the connecting hole between the screw 2 and the blind plate flange 1.

[0028] As a preferred embodiment, the cone head 7 is configured as a double cone head (such as the attached Figure 3 ), whether it is forward rotation or reverse rotation, it is beneficial to clean the discharge pipe 6. When the cleaning tool is not in use, in order to ensure the sealing effect, the handle 4 needs to be turned to fit with the flange blind plate 1. Therefore, at the beginning of cleaning, the screw 2 moves from the inside to the outside, and the bidirectional cone head can reduce the rotation resistance.

[0029] The working process of this utility model:

[0030] According to the blockage situation: if there is blockage but the material can still be conveyed normally, there is no need to close the valve 9, just rotate the handle 4 forward and reverse. After cleaning, rotate the handle 4 to press the sealing gasket 8 on the handle 4 against the sealing gasket 8 on the blind flange plate 1. If the blockage is serious and the material cannot be conveyed normally, close the valve 9 and rotate the handle 4 forward and reverse. During the rotation, the cone head 7 and the spiral blade 3 clear the blocked material in the discharge pipe and are pushed into the bottom of the container body 5 by the spiral blade 3. After the discharge pipe 6 is cleaned, rotate the handle 4 to press the sealing gasket on the handle 4 against the sealing gasket on the blind flange plate 1, and open the valve 9 to resume the normal conveying of the material.

[0031] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
