Description

Technical Field

[0001] The present application relates to the technical field of liquid storage tanks, and in particular to a liquid storage tank with visualized liquid level. Background Art

[0002] The liquid storage tank is a storage device for the refrigerant liquid located between the condenser and the evaporator in the adjustment system. There are a large number of liquid storage tanks in the food, chemical, petroleum and other industries. It is necessary to monitor the status of the liquid storage tank in real time to reduce the load of the condenser and act as a liquid seal to prevent gas from entering the low-pressure compressor. It can avoid excessive accumulation of condensate in the condenser, which will reduce the heat transfer area and affect the heat transfer effect of the condenser. The liquid storage tank also has a certain silencing and filtering effect.

[0003] For example, a Chinese patent (publication number: CN216402584U) discloses a visual liquid storage tank for real-time monitoring of liquid level. The user injects liquid into the filling tube and sets a float, a silk thread and a liquid storage tank body with a scale. When the liquid flows into the liquid level measuring tube, the float will float up due to its own weight. At this time, the user can read the value through the scale outside the liquid storage tank body. The set float will facilitate the user to read the value. The liquid level value of the left liquid storage tank body is compared with the liquid level value displayed on the right display screen, which can better monitor the liquid level value in the liquid storage tank body. After confirming the value, open the second valve and the liquid flows out through the liquid outlet pipe.

[0004] The above device sets a float in the tank, and uses the float and the liquid level scale in combination to read the value. Since the float is in the tank and the liquid level scale is outside the tank, the liquid outlet tank needs to be transparent. The liquid storage tank in the above device is made of glass, but the glass tank body is easy to break when it is bumped, so the safety is poor. Utility Model Content

[0012] Furthermore, the measuring component includes mounting grooves provided on the left and right sides of the bottom surface of the mounting plate, and a liquid level sensor fixed in the mounting grooves.

[0013] Beneficial effect of adopting a further technical solution: the liquid level inside the liquid storage tank can be monitored by using a liquid level sensor, and the remaining liquid inside the liquid storage tank can be known in conjunction with a scale plate.

[0014] Furthermore, a clearance hole for adding materials is provided at the center of the top surface of the mounting plate, the clearance hole is a circular hole, and the diameter of the clearance hole is larger than the diameter of the liquid inlet valve tube.

[0015] Beneficial effect of adopting the further technical solution: the relief hole is mainly used to facilitate the addition of supplementary liquid into the interior of the liquid storage tank.

[0016] Furthermore, the driving mechanism includes a screw rod rotatably connected to the left and right sides of the inner bottom wall of the base through bearings, a driven bevel gear fixed to the bottom end of the outer surface of the screw rod, and a driving assembly arranged inside the base.

[0018] Furthermore, the driving assembly includes a driving motor fixedly installed at the center of the inner bottom wall of the base, a driving shaft fixed to the left and right sides of the driving motor, and an active bevel gear fixed to one end of the driving shaft away from the driving motor and meshing with the driven bevel gear.

[0019] Beneficial effect of adopting the further technical solution: the drive assembly is mainly used to drive the screw to rotate.

[0020] Furthermore, the bottom ends of the two screw rods are rotatably connected to the bottom surfaces of the two fixing plates via bearings, and the threads on the outer surfaces of the two screw rods are in opposite directions.

[0021] The beneficial effect of adopting a further technical solution is that the screw rod can move the movable block up and down when rotating, and the two screw rods can also play a limiting role.

[0022] Furthermore, threaded holes are provided on the top surfaces of the two movable blocks, and the two screw rods respectively penetrate the two threaded holes and are threadedly connected thereto.

[0025] 1. The liquid level visualization liquid storage tank is equipped with an auxiliary mechanism, which uses a liquid level sensor to detect the remaining liquid inside the liquid storage tank. When the liquid level sensor cannot detect the liquid, it sends a signal to the controller, and the controller starts the driving mechanism to adjust the position of the movable block. The movable block will drive the pointer to move on the scale plate during the movement, and finally read the value indicated by the pointer. At the same time, the liquid storage tank made of stainless steel is safer.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figure 1-2 In this embodiment, a liquid level visualization liquid storage tank includes a base 1, a liquid storage tank 2 fixed at the center of the top surface of the base 1, a liquid inlet valve tube 3 is fixed at the center of the top surface of the liquid storage tank 2, a controller 4 is fixedly installed at the middle position of the right front side of the liquid storage tank 2, a driving mechanism 5 is provided on the liquid storage tank 2, and an auxiliary mechanism 6 for measuring the liquid level is provided on the driving mechanism 5, a fixing plate 7 is fixed at the middle position of the top of the left and right sides of the liquid storage tank 2, and a scale plate 8 is fixed to the back of the left and right sides of the liquid storage tank 2.

[0033] It should be noted that the values ​​on the scale plate 8 increase from top to bottom, and a liquid outlet valve pipe is fixedly installed at the center of the bottom of the front side of the liquid storage tank 2.

[0034] See also Figure 1-2 In order to facilitate the monitoring of the remaining liquid in the liquid storage tank 2, the auxiliary mechanism 6 includes two movable blocks 601 arranged on the driving mechanism 5, a pointer 608 fixed on the back of the movable block 601, a supporting component arranged on the movable block 601, and a measuring component arranged on the supporting component. The auxiliary mechanism 6 is mainly used to monitor the remaining liquid in the liquid storage tank 2, realize the function of real-time monitoring, and avoid safety accidents.

[0035] The support assembly includes a support plate 602 fixed to the opposite side of the two movable blocks 601, a support rod 603 fixed to the top surface of the support plate 602, and a mounting plate 604 fixed to the bottom end of the opposite side of the two support rods 603. The support rod 603 is in an inverted U shape.

[0036] Meanwhile, the measuring component includes mounting grooves 605 provided on the left and right sides of the bottom surface of the mounting plate 604 and a liquid level sensor 606 fixed in the mounting groove 605 . The liquid level sensor 606 can monitor the liquid remaining inside the liquid storage tank 2 .

[0037] In addition, a clearance hole 607 for adding materials is opened at the center of the top surface of the mounting plate 604. The clearance hole 607 is a circular hole. The diameter of the clearance hole 607 is larger than the diameter of the liquid inlet valve tube 3. When liquid is added to the liquid storage tank 2 through the liquid inlet valve tube 3, the liquid can enter the inner bottom of the liquid storage tank 2 through the clearance hole 607.

[0038] See also Figure 1 and Figure 3 In order to adjust the position of the liquid level sensor 606 on the mounting plate 604, the driving mechanism 5 includes a screw 504 rotatably connected to the left and right sides of the inner bottom wall of the base 1 through a bearing, a driven bevel gear 505 fixed to the bottom end of the outer surface of the screw 504, and a driving component arranged inside the base 1. The driving component can rotate the screw 504, and the rotation directions of the two screws 504 are opposite.

[0039] In addition, the driving assembly includes a driving motor 501 fixedly installed at the center of the inner bottom wall of the base 1, a driving shaft 502 fixed to the left and right sides of the driving motor 501, and an active bevel gear 503 fixed to the end of the driving shaft 502 away from the driving motor 501 and meshing with the driven bevel gear 505. The driving motor 501 can be used in conjunction with the active bevel gear 503 and the driven bevel gear 505 to drive the screw 504 to rotate.

[0040] It can be understood that the bottom ends of the two screw rods 504 are rotatably connected to the bottom surfaces of the two fixed plates 7 via bearings respectively, and the threads on the outer surfaces of the two screw rods 504 are in opposite directions. Since the rotation directions of the two screw rods 504 are opposite, structural interference will not occur only if the threads on their outer surfaces are also in opposite directions.

[0041] It should be emphasized that the top surfaces of the two movable blocks 601 are both provided with threaded holes, and the two screw rods 504 respectively penetrate the two threaded holes and are threadedly connected thereto. When the two screw rods 504 rotate forwards and backwards at the same time, the two movable blocks 601 can be driven to move up and down at the same time.

[0042] The working principle of the above embodiment is:

[0043] When in use, the liquid level sensor 606 can detect the liquid residue inside the liquid storage tank 2. When the liquid level sensor 606 cannot detect the liquid, it will send a signal to the controller 4, and the controller 4 will start the driving motor 501. The driving motor 501 drives the driving shaft 502 to rotate, and the driving shaft 502 drives the active bevel gear 503 to rotate. The active bevel gear 503 cooperates with the driven bevel gear 505 to drive the two screws 504 to rotate in opposite directions at the same time. The screw 504 can drive the movable block 601 to move upward during the rotation. At the same time, the mounting plate 604 moves downward under the push of the support rod 603 until the liquid level sensor 606 detects the liquid. At this time, the liquid level sensor 606 transmits the signal to the controller 4 again, and the controller 4 stops the operation of the driving motor 501. In addition, the movable block 601 will drive the pointer 608 on the support plate 602 to move on the scale plate 8 during the movement, and finally the value indicated by the pointer 608 can be read.
