Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid stirring tanks, in particular to a liquid stirring tank resistant to strong acids and alkalis. Background Art
[0002] Mixing tanks are widely used in the chemical, pharmaceutical, and food industries. Mixing tanks used in the chemical industry may need to be resistant to strong acids and alkalis. In this case, fiberglass mixing tanks are commonly used in existing technologies. Made from a composite of glass fiber and synthetic resin, they offer excellent corrosion resistance and are able to withstand the erosion of various acids, alkalis, salts, and other chemical media. Polypropylene (PP / PPH) mixing tanks are also chemically resistant and can withstand the erosion of various strong acids, alkalis, and other chemicals, and are not prone to aging.
[0003] However, these mixing tanks lack leakage alarms during use. Although these mixing tanks are corrosion-resistant, they still pose a risk of leakage during long-term use. For example, if a strong acid or alkali leaks from the device due to a collision, without a timely alarm, it is easy to cause unnecessary safety hazards. Therefore, there is a need for an improved liquid mixing tank that is resistant to strong acids and alkalis. Utility Model Content
[0004] The purpose of the utility model is to provide a liquid stirring tank resistant to strong acids and alkalis, so as to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a liquid stirring tank resistant to strong acids and alkalis, comprising a fixed plate, a storage shell being provided at the lower end of the fixed plate, a detection shell being fixedly provided on the outside of the storage shell, a protective shell being fixedly provided on the outside of the detection shell, a detection mechanism being provided inside the detection shell for detecting whether the storage shell is leaking, the detection mechanism comprising a detection cavity, a detection tube, a functional chamber, a piston, a spring, a trigger switch, and a buzzer, a detection cavity being provided between the detection shell and the storage shell, a detection tube being fixedly provided on one side of the upper end of the detection cavity, the detection tube being inserted through the detection shell and extending to the outside of the detection shell, a functional chamber being fixedly provided at one end of the detection tube, a piston being movably engaged with a piston being provided in the middle of the inner side of the functional chamber, a spring being fixedly provided on one side of the inner side of the functional chamber, an end of the spring close to the piston being fixedly connected to the piston, a trigger switch being fixedly provided in the middle of the inner side of the functional chamber, and a buzzer being fixedly provided on the outer side of the functional chamber.
[0006] Preferably, the interior of the detection cavity is a vacuum, so that the interior of the functional chamber is a vacuum on the side of the piston close to the detection cavity, and the interior of the functional chamber is a normal pressure on the side of the piston away from the detection cavity, so that a pressure difference is generated. Such a pressure difference can push the piston to move in the direction close to the detection cavity and cause the spring to be stretched. At this time, as long as there is damage and leakage inside the storage shell, the vacuum inside the detection cavity is broken, and the air pressure on both sides of the piston is balanced. At this time, the spring can pull the piston in the direction close to the trigger switch under the action of its own elastic force, thereby squeezing the trigger switch, making the trigger switch conductive, and controlling the buzzer to alarm. At this time, the staff can know that the storage shell has leaked; (of course, the present device may also have a leak in the detection shell, in which case the alarm will also be triggered, and the detection shell should also be timely interrupted when it leaks to prevent the storage shell from actually leaking and failing to alarm in time.
[0007] Preferably, an electric motor is fixedly provided on the upper end of the fixed plate, and a stirring rod is movably provided on the middle part of the inner side of the storage shell through a bearing. The output shaft end of the motor is transmission-connected to the stirring rod, and the stirring rod can be driven to rotate by the motor, thereby stirring and mixing the material inside the storage shell.
[0008] Preferably, a protective cavity is provided between the protective shell and the detection shell. This protective cavity can provide the protective shell with a certain amount of collapse space when the protective shell is impacted, and will not squeeze the detection shell, thereby improving the protection effect of the device.
[0009] Preferably, the trigger switch is electrically connected to the buzzer, and when the trigger switch is squeezed, the buzzer can be controlled to be powered on and sound an alarm.
[0010] Preferably, a connecting pipe is fixedly provided between the protection housing and the detection housing, and a pump device can be connected through the connecting pipe to evacuate the detection cavity.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] With the long-term use of the device of the present invention, there may be a risk of leakage in the storage shell. As long as the storage shell leaks and is damaged, no matter how large the damaged opening is, the vacuum inside the detection cavity will fail. At this time, the air pressure on both sides of the piston is balanced. At this time, the spring can pull the piston toward the trigger switch under the action of its own elastic force, thereby squeezing the trigger switch and turning on the trigger switch, thereby controlling the buzzer to alarm. At this time, the staff can know that the storage shell is leaking and needs to be repaired in time.
[0013] When the present invention is in use, there is also a protective shell. In this way, when the device is working, the protective shell will withstand the impact when it is hit by any form of impact from the outside. At this time, the protective cavity can give the protective shell a certain amount of collapse space when the protective shell is hit, and will not squeeze the detection shell, thereby improving the protection effect of the device.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-4The utility model provides a technical solution: a liquid stirring tank resistant to strong acids and alkalis, comprising a fixed plate 1, a storage shell 2 is provided at the lower end of the fixed plate 1, a detection shell 4 is fixedly provided on the outside of the storage shell 2, a protective shell 4 is fixedly provided on the outside of the detection shell 4, a detection mechanism for detecting whether the storage shell 2 is leaking is provided inside the detection shell 4, the detection mechanism includes a detection cavity 5, a detection tube 6, a functional compartment 7, a piston 8, a spring 9, a trigger switch 10, and a buzzer 11, a detection cavity 5 is provided between the detection shell 4 and the storage shell 2, a detection tube 6 is fixedly provided on one side of the upper end of the detection cavity 5, the detection tube 6 is inserted through the detection shell 4 and extends to the outside of the detection shell 4, a functional compartment 7 is fixedly provided on one end of the detection tube 6, a piston 8 is movably engaged with the inner middle part of the functional compartment 7, a spring 9 is fixedly provided on one side of the inner side of the functional compartment 7, an end of the spring 9 close to the piston 8 is fixedly connected to the piston 8, a trigger switch 10 is fixedly provided in the inner middle part of the functional compartment 7, and a buzzer 11 is fixedly provided on the outer side of the functional compartment 7.
[0021] The detection cavity 5 is vacuum, so that the inside of the functional chamber 7 is vacuum on the side where the piston 8 is close to the detection cavity 5, and the inside of the functional chamber 7 is normal pressure on the side where the piston 8 is away from the detection cavity 5, so that a pressure difference is generated on the left and right. Such a pressure difference can push the piston 8 to move in the direction close to the detection cavity 5 and cause the spring 9 to be stretched. At this time, as long as there is damage and leakage in the storage shell 2, the vacuum in the detection cavity 5 is broken, and the air pressure on both sides of the piston 8 is balanced. At this time, the spring 9 can pull the piston 8 in the direction close to the trigger switch 10 under the action of its own elastic force, thereby squeezing the trigger switch 10, making the trigger switch 10 conductive, thereby controlling the buzzer 11 to alarm, and the staff can now know that the storage shell 2 is leaking; (of course, this device may also have a leak in the detection shell 4, in which case the alarm will also be triggered, and the detection shell 4 should also be timely interrupted if it leaks, to prevent the subsequent storage shell 2 from really leaking and failing to alarm in time;
[0022] A motor 12 is fixedly provided on the upper end of the fixed plate 1, and a stirring rod 13 is movably provided on the middle part of the inner side of the storage shell 2 through a bearing. The output shaft end of the motor 12 is transmission-connected to the stirring rod 13. The motor 12 can drive the stirring rod 13 to rotate, thereby stirring and mixing the materials inside the storage shell 2.
[0023] A protective cavity 14 is provided between the protective shell 4 and the detection shell 4. This protective cavity 14 can provide the protective shell 4 with a certain amount of space to collapse when the protective shell 4 is hit, so as not to squeeze the detection shell 4, thereby improving the protection effect of the device.
[0024] The trigger switch 10 is electrically connected to the buzzer 11. When the trigger switch 10 is squeezed, the buzzer 11 can be controlled to be powered on and alarmed.
[0025] A connecting pipe 15 is fixedly provided between the protection housing 4 and the detection housing 4 , and a pump device can be connected through the connecting pipe 15 to evacuate the detection cavity 5 .
[0026] Working principle: When using this device, the storage shell 2 can be used to store strong acids or strong bases and then carry out subsequent mixing and processing work. However, with the long-term use of the device, the storage shell 2 may be at risk of leakage. As long as the storage shell 2 leaks and is damaged, no matter how large the damaged opening is, the vacuum inside the detection cavity 5 will fail. At this time, the air pressure on both sides of the piston 8 is balanced. At this time, the spring 9 can pull the piston 8 toward the trigger switch 10 under the action of its own elastic force, thereby squeezing the trigger switch 10 and turning on the trigger switch 10, thereby controlling the buzzer 11 to alarm. At this time, the staff can know that the storage shell 2 is leaking and needs to be repaired in time.
[0027] When the device is in use, the protective shell 4 is also present. In this way, when the device is working, the protective shell 4 will withstand any form of impact from the outside. At this time, the protective cavity 14 can provide the protective shell 4 with a certain amount of collapse space when the protective shell 4 is hit, and will not squeeze the detection shell 4, thereby improving the protection effect of the device.
[0028] It should be noted that since the detection shell 4 is only two-thirds the height of the storage shell 2, in order to ensure that the leakage of strong acid and alkali solution can be detected in time after the storage shell 2 leaks, the height of the solution stored inside the storage shell 2 should be lower than two-thirds of the internal height of the storage shell 2.
[0029] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
