Description

Technical Field

[0001] The utility model relates to the technical field of dosing pumps, in particular to a vertical dosing pump which is easy to adjust. Background Art

[0002] A vertical dosing pump is a device used for dosing. It is usually designed vertically and installed vertically on a dosing container or pipeline. The design of this pump makes it suitable for various industrial, chemical, water treatment and other scenarios. It is used to transport liquids or chemicals into the system. Vertical dosing pumps usually have an adjustment function, allowing users to adjust the flow or pressure of the pump under different working conditions. The adjustment is usually achieved by adjusting the pump speed, blade position or control valve.

[0003] After searching, the Chinese patent document with the announcement number CN203640947U discloses a vertical high-pressure automatic dosing pump. It includes a cylindrical pump body with a center hole, a through hole on the side wall of the pump body and connected to the bottom end of the bent liquid outlet pipe, the lower axis of the bent liquid outlet pipe is set at an angle with the axis of the pump body, the upper axis of the bent liquid outlet pipe is vertical and connected to the liquid outlet valve body, the upper opening of the pump body is connected to the sealing packing lower pressure cap, the lower opening is connected to the liquid inlet valve body, the adjusting nut is screwed with the top of the plunger and fixed to the upper end surface of the pressure plate through the locking nut, the lower end surface of the pressure plate is against the upper end of the spring, the lower end of the spring is against the sealing packing gland, the sealing packing gland is connected to the sealing packing lower pressure cap, and the plunger passes through the center holes of the pressure plate, the sealing packing gland and the sealing packing lower pressure cap in turn, and enters the center hole of the pump body. The utility model can directly add the medicine into the wellhead back pressure pipeline with pressure and fully mix it with the well fluid in the pipeline, so as to achieve a better dosing effect and reduce the waste of medicine.

[0004] The working principle of the above patent specification mentions that "the inlet valve 10 of the vertical high-pressure automatic dosing pump is installed at the bottom end of the pump body 9, and the outlet valve 14 is installed at the upper end of the entire vertical high-pressure automatic dosing pump through a bent outlet pipe 12. The outlet pipe 12 is a bent structure, and the angle between the lower axis of the bent part of the outlet pipe 12 and the axis of the pump body 9 is 45° to 60°.

During the movement of the pull plate 8, the limit block 9 will be driven to move. The other end of the spring 7 is fixedly connected to one side of the limit block 9, and the spring 7 will be squeezed during the movement. When subjected to force and compression, the cavity 6 will absorb the external force generated by the limit block 9, and at the same time, the cavity 6 will rotate with the movement of the pull plate 8. The top of the pull plate 8 is rotatably connected to the connecting shaft 10, and the top of the cavity 6 is fixedly connected to the spring 2 11. When the cavity 6 is in a vertical state, the spring 2 11 will be squeezed upward. The spring 2 11 will absorb the external force brought by the cavity 6 when subjected to force and compression. The bottom of the spring 2 11 rotates on the top of the connecting shaft 10. The left and right sides of the filter plate 5 are provided with a card slot 12. The outer side of one side of the pull plate 8 is engaged with the inner wall of the card slot 12. At this time, the pull plate 8 is separated from the card slot 12, and the filter plate 5 can be removed for cleaning. When installing, put the filter plate 5 into the inside of the medicine inlet pipe 4, and pull the pull plate 8 again. At this time, the spring 1 7 and the spring 2 11 are compressed again. When the pull plate 8 contacts the slot 12, release the pull plate 8. At this time, the spring 1 7 will release the external force to generate a reaction force on the limit block 9, and the spring 2 11 will also release the external force and generate a reaction force on the cavity 6 when the cavity 6 moves. Under the reaction force of the spring 1 7 and the spring 2 11, the pull plate 8 and the slot 12 are engaged, that is, the installation is successful, the filtering of particles in the medicine solution is realized, and the filter plate 5 can be quickly disassembled and installed, which is convenient for cleaning the filter plate 5 and ensures the filtering effect of the filter plate 5.

[0025] Reference Figure 1 and Figure 3The upper and lower sides of the medicine inlet pipe 4 are fixedly connected with a connecting pipe 13, and the outside of the connecting pipe 13 is fixedly connected with a fixing frame 14. The fixing frame 14 can further fix the connecting pipe 13 to prevent the connecting pipe 13 from shaking.

The outside of the hose 15 contacts the inner wall of the regulating pipe 16, and the adjacent side of the fixing frame 14 is respectively fixedly connected to the upper and lower sides of the medicine inlet pipe 4. The other end of the connecting pipe 13 is fixedly connected with an regulating pipe 16, and a plurality of regulating grooves 17 are provided on the outside of the regulating pipe 16. An adjusting component is provided on the top of the medicine inlet pipe 4, and the adjusting component includes a fixing ring 18 and a plurality of rubber balls 19. When the flow rate needs to be adjusted, the fixing ring is pushed upward. 18. Under the movement of the fixing ring 18, the rubber ball 19 moves upward along the adjusting groove 17, the outer part of the fixing ring 18 is slidably connected to the outer part of the adjusting tube 16, the outer part of the rubber ball 19 is fixedly connected to the inner wall of the fixing ring 18, the outer part of the rubber ball 19 contacts the outer wall of the adjusting groove 17, and the outer part of the rubber ball 19 contacts the outer wall of the hose 15. At this time, the rubber ball 19 contacts the hose 15. The higher the fixing ring 18 is pushed, the larger the contact area between the rubber ball 19 and the hose 15 will be. The hose 15 is squeezed and contracted inwardly, thereby the flow rate of the hose 15 will become smaller. When the flow rate needs to be increased, the fixing ring 18 is pushed downward, the contact area between the rubber ball 19 and the hose 15 will be smaller, and the flow rate will increase, thereby realizing the adjustment of the flow rate and conveniently controlling the speed of dosing.

Turning the valve 3 can timely control the entry of the medicine liquid inside the medicine inlet pipe 4. At this time, under the operation of the pump body 1, the medicine liquid inside the medicine tank is extracted through the medicine inlet pipe 4. When the medicine liquid enters the medicine inlet pipe 4, the particles inside the liquid will be filtered through the filter plate 5. Then the medicine liquid will enter the tank body that needs to be added with liquid through the hose 15. When the flow rate needs to be adjusted, push the fixing ring 18 upward. Under the movement of the fixing ring 18, the rubber ball 19 moves upward along the adjusting groove 17. At this time, the rubber ball 19 contacts the hose 15. The higher the fixing ring 18 is pushed, the larger the contact area between the rubber ball 19 and the hose 15 will be, and the hose 15 will be squeezed inwardly by force, so that the flow rate of the hose 15 will become smaller. When the flow rate needs to be increased, the fixing ring 18 is pushed downward, the contact area of ​​the rubber ball 19 and the hose 15 becomes smaller, and the flow rate will increase. After a period of use, particulate matter will be attached to the outside of the filter plate 5 and needs to be cleaned in time. At this time, the pull plate 8 is pulled outward, and the limit block 9 will be driven to move during the movement of the pull plate 8. The spring 1 7 will be squeezed during the movement, and the cavity 6 will rotate with the movement of the pull plate 8. When the cavity 6 is in a vertical state, the spring 2 11 will be squeezed upward. At this time, the pull plate 8 is separated from the slot 12, and the filter plate 5 can be removed for cleaning. When installing, the filter plate 5 is placed inside the medicine inlet pipe 4, and the pull plate 8 is pulled again. At this time, the spring 1 7 and the spring 2 11 are compressed again. When the pull plate 8 contacts the slot 12, the pull plate 8 is released. Under the reaction force of the spring 1 7 and the spring 2 11, the pull plate 8 and the slot 12 are engaged, that is, the installation is successful.
