Description

Technical Field

[0001] This invention belongs to the field of regulating equipment technology, specifically a liquid level regulating device for a horizontal storage tank. Background Technology

[0002] Liquid is one of the four fundamental states of matter. It has no definite shape but a certain volume and exhibits motion such as movement and rotation. Liquids are composed of tiny vibrating particles held together by intermolecular forces. Storage tanks are needed for storing liquids. Commonly used tanks are vertical and horizontal. Due to the large volume of chemical liquids required for industrial storage, horizontal tanks with larger capacities are usually used for storage and transportation.

[0003] Because the inlet of a horizontal liquid storage tank is located at the top and the outlet at the bottom, the stored material can be discharged by hydraulic pressure and gravity inside the tank during operation. However, this causes the outlet at the bottom to be constantly subjected to hydraulic pressure. Even if the outlet is sealed with relevant sealing equipment, the vulnerable points at the inlet may still leak due to the hydraulic pressure during long-term storage, leading to leakage of the stored material. Therefore, improvements are needed. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical solution adopted by the present invention to solve its technical problem is: a liquid level regulating device for a horizontal storage tank, including a cylindrical component, wherein connecting components are symmetrically arranged on both sides of the cylindrical component;

[0005] The cylindrical component includes a storage tank. Torque motors are symmetrically arranged on the left and right sides of the inner wall of the storage tank. An inner rotating shaft device is provided on the outer surface of the output shaft of the torque motor. Inner sealing devices are symmetrically arranged on the left and right sides of the inner rotating shaft device. Infusion devices are symmetrically arranged on both sides of the top of the inner cavity of the storage tank. A draining device is provided at the axis at the bottom of the inner cavity of the storage tank.

[0006] The connecting component includes a double-section push rod. One end of the double-section push rod is fixedly connected to the axis of the outer surface of the torque motor. The other end of the double-section push rod is fixedly connected to a pressure control pump through a connecting pipe. The middle part of the outer surface of the double-section push rod is fixedly connected to the axis of the inner cavity of the storage tank through a through-hole. The double-section push rod consists of an outer rod shell and an inner sliding rod. The rod shell is fixedly fixed to the axis of the storage tank. The end of the sliding rod is fixedly connected to the middle part of the outer surface of the torque motor. A reinforcing plate is fixedly connected to the side of the outer surface of the double-section push rod away from the torque motor. A vertical push plate is fixedly connected to the top of the reinforcing plate. A fixed top plate is fixedly connected to the top of the vertical push plate.

[0007] Furthermore, the inner rotating shaft device includes a shaft guide rod, and pressure-sensing connecting rods are symmetrically arranged on both sides of the inner cavity of the shaft guide rod. A spring pressure rod is fixedly connected to the end of the pressure-sensing connecting rod away from the shaft guide rod, and a secondary baffle is fixedly connected to the end of the spring pressure rod away from the pressure-sensing connecting rod.

[0008] Furthermore, the inner sealing device includes an adapter housing, with inner sealing plates symmetrically arranged on the upper and lower sides of the outer surface of the adapter housing. A pressure-sensing inner ring is fixedly connected to the inner wall of the adapter housing on the side away from the shaft guide rod. Hollow connecting tubes are evenly arranged on the inner cavity of the adapter housing near the shaft guide rod. A filling spacer is fixedly connected to the end of the hollow connecting tube away from the adapter housing. The shaft of the adapter housing and the shaft of the filling spacer can slide in a direction through the guide grooves on both sides of the outer surface of the shaft guide rod. Therefore, when the shaft guide rod rotates, it can drive the adapter housing and the filling spacer to rotate.

[0009] Furthermore, there are two adapter shells and two inner sealing plates. The outer surface of the inner sealing plate is slidably connected to the inner wall of the storage tank. One end of the hollow connecting tube near the pressure-sensing inner ring is fixedly connected to the inner cavity of the adapter shell through a through-hole. The side of the filling septum is slidably connected to the inner wall of the inner sealing plate. There are four pressure-sensing connecting rods, and the end of the pressure-sensing connecting rod away from the inner wall of the storage tank is fixedly connected to the outer surface of the axial guide rod. The outer surface of the auxiliary baffle is slidably connected to the inner wall of the storage tank. Both sides of the outer surface of the axial guide rod are slidably connected to the axial center of the inner wall of the filling septum.

[0010] Furthermore, the drainage device includes an external tube shell, with a matching bottom cylinder rotatably connected to the axis at the bottom of the inner wall of the external tube shell. A collecting disk is fixedly connected to the bottom of the inner wall of the matching bottom cylinder, and connecting pipes are evenly arranged in the inner cavity of the collecting disk. A spring washer is fitted onto the bottom of the outer surface of the connecting pipe. Friction wheels are symmetrically arranged on both sides of the bottom of the inner wall of the external tube shell, and a control turntable is fixedly connected to the top of the axis of the friction wheels. A discharge plug is rotatably connected to the top of the inner wall of the matching bottom cylinder, and discharge ports are evenly arranged in the inner cavity of the discharge plug.

[0011] Furthermore, the top of the outer tube shell is fixedly connected to the bottom of the outer surface of the storage tank, the top of the discharge plug is fixedly connected to the axis at the bottom of the inner cavity of the storage tank through a through-hole, the top of the connecting pipe is rotatably connected to the lower surface of the discharge plug, and the outer surface of the friction wheel is rolledly connected to the outer surface of the outer tube shell through a rotating groove. Each mesh opening of the discharge plug can correspond one-to-one with the connecting pipe below. When the connecting pipe and the discharge plug are successfully connected, the storage material can be directly discharged downward through the adapter bottom cylinder.

[0012] Furthermore, the infusion device includes a docking outer shell, a movable inner liner slidably connected to the middle of the inner wall of the docking outer shell, segmented tie rods evenly arranged on the upper surface of the movable inner liner, drainage grooves evenly formed in the lower part of the inner cavity of the movable inner liner, and a compression washer fitted onto the outer surface of the movable inner liner. Two infusion devices are used. The bottom of the compression washer is fixedly connected to the bottom of the inner wall of the docking outer shell, the bottom of the outer surface of the docking outer shell is fixedly connected to the top of the inner cavity of the storage tank, the top of the segmented tie rods is fixedly connected to the inner cavity of the docking outer shell, and the bottom end of the movable inner liner extends into the interior of the storage tank through a through-hole.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. The storage tank of this device has corresponding through-holes on the upper and lower sides for the exchange of stored liquid. However, this will cause the discharge port and the inlet to be subjected to the hydraulic pressure of the stored liquid. The vulnerable points of the through-holes may also leak due to the hydraulic pressure, resulting in leakage of the stored material. This device protects the through-holes of the storage tank from the inside without interfering with the normal liquid infusion and discharge operation by using inner sealing plates on both sides of the inner sealing equipment, thereby avoiding the above problems.

[0015] 2. This device can use internal filling baffles to push the liquid inside the storage tank towards the center, thereby raising the liquid level inside the storage tank and regulating the liquid level inside the tank. This ensures that the hydraulic pressure inside the storage tank is large enough so that the liquid inside the storage tank can be drained smoothly even when the storage volume is small. The internal pressure-sensing inner ring monitors the hydraulic pressure inside the storage tank, allowing for more flexible adjustment of the liquid level inside the storage tank.

[0016] 3. During infusion, to ensure the sealing of the drain port at the bottom of the storage tank, the guide rod needs to be twisted so that the auxiliary baffles on both sides rotate to the vertical direction. When the infusion is in progress, the input hydraulic pressure will push the upper auxiliary baffle downward, compressing the spring rod. Then, the pressure feedback of the infusion pressure is transmitted through the pressure-sensing linkage to avoid excessive pressure difference between the inside of the storage tank and the infusion pipe, which could lead to infusion difficulties or over-infusion.

[0017] 4. When the liquid is introduced, the external hydraulic pressure will push the movable inner liner into the storage tank, and then discharge it directly into the storage tank through the drain groove of the movable inner liner. When the hydraulic pressure inside the storage tank is about to reach the threshold, the external hydraulic pressure will gradually decrease. At this time, the compressed segmented tie rod and compression washer will gradually push the movable inner liner into the docking shell, thereby retracting the part where the drain groove is located into the docking shell, preventing the liquid inside the storage tank from flowing back out.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0028] Example 1, please refer to Figures 1-5The present invention provides a technical solution: a liquid level regulating device for a horizontal storage tank, including a cylindrical component 1, and connecting components 2 symmetrically arranged on both sides of the cylindrical component 1;

[0029] The cylindrical component 1 includes a storage tank 11. Torque motors 12 are symmetrically arranged on the left and right sides of the inner wall of the storage tank 11. An inner rotating shaft device 14 is provided on the outer surface of the output shaft of the torque motor 12. An inner sealing device 13 is symmetrically arranged on the left and right sides of the inner rotating shaft device 14. Infusion devices 3 are symmetrically arranged on both sides of the top of the inner cavity of the storage tank 11. A draining device 4 is provided at the axis at the bottom of the inner cavity of the storage tank 11.

[0030] The connecting component 2 includes a double-section push rod 21. One end of the double-section push rod 21 is fixedly connected to the shaft center of the outer surface of the torque motor 12. The other end of the double-section push rod 21 is fixedly connected to a pressure control pump through a connecting pipe 23. The middle part of the outer surface of the double-section push rod 21 is fixedly connected to the shaft center of the inner cavity of the storage tank 11 through a through-hole. The double-section push rod 21 is composed of an outer rod shell and an inner sliding rod. The rod shell part is fixed at the shaft center of the storage tank 11. The end of the sliding rod is fixedly connected to the middle part of the outer surface of the torque motor 12. A reinforcing plate 22 is fixedly connected to the side of the outer surface of the double-section push rod 21 away from the torque motor 12. A vertical push plate 24 is fixedly connected to the top of the reinforcing plate 22. A fixed top plate 25 is fixedly connected to the top of the vertical push plate 24.

[0031] The inner rotating shaft device 14 includes a shaft guide rod 141. Pressure-sensing connecting rods 142 are symmetrically arranged on both sides of the inner cavity of the shaft guide rod 141. A spring pressure rod 143 is fixedly connected to one end of the pressure-sensing connecting rod 142 away from the shaft guide rod 141. A secondary baffle 144 is fixedly connected to one end of the spring pressure rod 143 away from the pressure-sensing connecting rod 142.

[0032] The inner sealing device 13 includes an adapter housing 131. Inner sealing plates 135 are symmetrically arranged on the upper and lower sides of the outer surface of the adapter housing 131. A pressure-sensing inner ring 132 is fixedly connected to the inner wall of the adapter housing 131 away from the shaft guide rod 141. Hollow connecting pipes 133 are evenly arranged on the inner cavity of the adapter housing 131 near the shaft guide rod 141. A filling septum 134 is fixedly connected to the end of the hollow connecting pipe 133 away from the adapter housing 131. The shaft of the adapter housing 131 and the shaft of the filling septum 134 can slide in a direction through the guide grooves on both sides of the outer surface of the shaft guide rod 141. Therefore, when the shaft guide rod 141 rotates, it can drive the adapter housing 131 and the filling septum 134 to rotate.

[0033] There are two adapter shells 131 and two inner sealing plates 135. The outer surface of the inner sealing plate 135 is slidably connected to the inner wall of the storage tank 11. The end of the hollow connecting pipe 133 near the pressure-sensing inner ring 132 is fixedly connected to the inner cavity of the adapter shell 131 through a through-hole. The side of the filling septum 134 is slidably connected to the inner wall of the inner sealing plate 135. There are four pressure-sensing connecting rods 142. The end of the pressure-sensing connecting rod 142 away from the inner wall of the storage tank 11 is fixedly connected to the outer surface of the shaft guide rod 141. The outer surface of the auxiliary baffle 144 is slidably connected to the inner wall of the storage tank 11. Both sides of the outer surface of the shaft guide rod 141 are slidably connected to the axis of the inner wall of the filling septum 134.

[0034] The device drains liquid through the bottom draining device 3. Under normal circumstances, it is necessary to protect the draining plug to prevent the liquid inside the cylinder from leaking due to prolonged hydraulic pressure. During normal draining, the plug is opened, and normal draining is carried out by hydraulic pressure.

[0035] When using this device, the liquid is injected into the cylinder component 1 through the two infusion devices 3 above. Then, the infusion tube is pulled out from the infusion device 3, and the infusion device 3 can automatically close and then carry out normal liquid storage.

[0036] During storage, the torque motors 12 on both sides can rotate the shaft guide rod 141 through the rotating shaft, causing the inner sealing device 13 to deflect synchronously. At this time, the inner sealing plate 135, which is stuck in the grooves on both sides of the adapter housing 131, is directly twisted, causing the inner sealing plate 135 to rotate to the upper and lower sides, as if... Figure 3 As shown, at this time, the upper inner sealing plate 135 blocks the outlet of the infusion device 3, and the lower inner sealing plate 135 blocks the outlet of the lower drainage device 4, thereby reducing the hydraulic pressure caused by the liquid stored inside the storage tank 11 on the outlet.

[0037] The pressure pumps on both sides pressurize the inner shell of the double-stage push rod 21 through the connecting pipe 23. At this time, the solid rod inside the double-stage push rod 21 pushes the torque motors 12 on both sides towards the middle of the storage tank 11 through pressure, thereby achieving the effect of adjusting the liquid level. At this time, the inner sealing device 13 will slide along the axis guide rod 141, and the hydraulic pressure inside the storage tank 11 will also generate a reaction force on the filling septa 134 on both sides, so that the filling septa 134 presses the hollow connecting pipe 133. The hollow connecting pipe 133 pressurizes the inside of the fitting shell 131. The hydraulic pressure inside the storage tank 11 is judged by the air pressure fed back by the pressure sensing inner ring 132, thereby avoiding the problem of the stored liquid directly pressurizing the pressure sensing inner ring 132 and causing water to enter the pressure sensing inner ring 132.

[0038] During infusion, the central guide rod 141 is twisted to rotate the two side sub-baffles 144 to the vertical direction. At this time, the lower sub-baffle 144 replaces the inner sealing plate 135 to protect the discharge port, while the upper sub-baffle 144 obstructs the infusion process. When the infusion is in progress, the input hydraulic pressure will push the upper sub-baffle 144 downward, causing the spring pressure rod 143 to be squeezed, and then the pressure of the infusion will be fed back through the pressure-sensing connecting rod 142.

[0039] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: Based on Embodiment 1, the drainage device 4 includes an external tube shell 41, an adapter bottom cylinder 45 rotatably connected to the axis at the bottom of the inner wall of the external tube shell 41, a gathering disk 46 fixedly connected to the bottom of the inner wall of the adapter bottom cylinder 45, a connecting pipe 47 evenly arranged in the inner cavity of the gathering disk 46, and a spring washer 48 sleeved on the bottom of the outer surface of the connecting pipe 47. Friction wheels 44 are symmetrically arranged on both sides of the bottom of the inner wall of the external tube shell 41, a control turntable 43 is fixedly connected to the top of the axis of the friction wheel 44, and a discharge plug 42 is rotatably connected to the top of the inner wall of the adapter bottom cylinder 45, and a discharge port is evenly arranged in the inner cavity of the discharge plug 42.

[0040] The top of the outer tube shell 41 is fixedly connected to the bottom of the outer surface of the storage tank 11. The top of the discharge plug 42 is fixedly connected to the axis at the bottom of the inner cavity of the storage tank 11 through the through-hole. The top of the connecting pipe 47 is rotatably connected to the lower surface of the discharge plug 42. The outer surface of the friction wheel 44 is rolledly connected to the outer surface of the outer tube shell 41 through the rotating groove. Each mesh opening of the discharge plug 42 can correspond one-to-one with the connecting pipe 47 below. When the connecting pipe 47 and the discharge plug 42 are successfully connected, the storage material can be directly discharged downward through the adapter bottom cylinder 45.

[0041] The infusion device 3 includes a docking outer shell 31, a movable inner liner 33 slidably connected to the middle of the inner wall of the docking outer shell 31, segmented pull rods 32 evenly arranged on the upper surface of the movable inner liner 33, drainage grooves 34 evenly opened in the lower part of the inner cavity of the movable inner liner 33, and compression washers 35 fitted onto the outer surface of the movable inner liner 33. There are two infusion devices 3. The bottom of the compression washers 35 is fixedly connected to the bottom of the inner wall of the docking outer shell 31, the bottom of the outer surface of the docking outer shell 31 is fixedly connected to the top of the inner cavity of the storage tank 11, the top of the segmented pull rods 32 is fixedly connected to the inner cavity of the docking outer shell 31, and the bottom end of the movable inner liner 33 extends into the interior of the storage tank 11 through a through-hole.

[0042] During the drainage process, the corresponding drainage pipe is connected to the bottom of the outer casing 41. Then, the internal control turntable 43 rotates the adapter bottom cylinder 45 through the friction wheel 44, causing the clustering disk 46 inside the adapter bottom cylinder 45 to deflect. Then, the connecting pipe 47 is aligned with the bottom end of the discharge plug 42. At this time, the liquid inside the storage tank 11 can be smoothly discharged through the discharge plug 42. When the connecting pipe 47 and the discharge plug 42 are completely misaligned, the liquid discharged from the discharge plug 42 will be directly blocked by the clustering disk 46, and external air cannot enter the storage tank 11 through the connecting pipe 47.

[0043] When the liquid is introduced, the external hydraulic pressure will push the movable inner liner 33 into the storage tank 11, and then discharge it directly into the storage tank 11 through the drain groove 34 of the movable inner liner 33. When the hydraulic pressure inside the storage tank 11 is about to reach the threshold, the external hydraulic pressure will gradually weaken. At this time, the compressed segmented tie rod 32 and compression washer 35 will gradually push the movable inner liner 33 into the docking outer shell 31, thereby retracting the part where the drain groove 34 is located back into the docking outer shell 31 to prevent the liquid inside the storage tank 11 from flowing back out.

[0044] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
