Description

Technical Field

[0001] This utility model relates to the field of heater technology, specifically to a water level safety interlock device for a low-temperature heater. Background Technology

[0002] A cryogenic heater is a device specifically designed to heat objects, media, or spaces within a relatively low temperature range (typically much lower than the operating temperature of conventional heating equipment). Its principle is primarily based on heat transfer methods such as heat conduction, heat convection, or heat radiation. Energy is converted from electrical, chemical, or other forms of energy into heat energy, and then transferred to the target object or space using a suitable heat transfer method, raising its temperature. For example, an electric cryogenic heater uses an electric current passing through a resistance wire to generate heat, which is then dissipated through heat conduction or heat convection; while an infrared cryogenic heater directly heats the object by emitting infrared radiation.

[0003] When using cryogenic heaters, because they contain a certain amount of water and have a certain heat storage capacity, it is not possible to effectively monitor and control the water level in real time to ensure that the water level remains within a safe range. This makes it easy for the cryogenic heater to be damaged and cause safety accidents when the water level is too high or too low. Therefore, in order to solve the above problems, a cryogenic heater water level safety interlock device is proposed. Summary of the Invention

[0004] The purpose of this utility model is to provide a safety interlock device for the water level of a cryogenic heater, in order to solve the problem mentioned in the background art that, because the cryogenic heater contains a certain amount of water and has a certain heat storage capacity, it is not possible to effectively monitor and control the water level of the cryogenic heater in real time to ensure that the water level is kept within a safe range. This makes it easy for the cryogenic heater to be damaged and cause safety accidents when the water level is too high or too low.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature heater water level safety interlock device, comprising a housing, the housing comprising a body, a water inlet fixedly connected to the top of the body, a drain pipe fixedly connected to the bottom of the body, a sewage pipe fixedly connected to the bottom of the body, and a heating element provided on the inner side of the body;

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By using a float, the float can change its position inside the vessel when the water level changes. This allows the connecting rod to drive the movable plate to move vertically. The movement of the movable plate, along with contact and compression with the first and second pressure sensors, enables monitoring of the water level inside the vessel. Combined with the mounting plate and buzzer, this allows for timely drainage and replenishment of water when the water level is abnormal. The buzzer also alerts staff, helping to ensure a safe water level range, thereby extending the service life of the cryogenic heater and ensuring staff safety.

[0014] The positioning block and the positioning slot allow for precise and convenient installation of the controller, making it easier to use. The movement of the insertion rod within the mounting plate, combined with a spring mechanism, allows for insertion and release of the slot, facilitating the fixing and unfixing of the positioning slot. This makes it easy to disassemble, replace, repair, and maintain the controller, ensuring effective water level monitoring. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] The controller 21, buzzer 22, first pressure sensor 28 and second pressure sensor 210 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0025] A water level safety interlock device for a low-temperature heater includes a housing, the housing including a body 1, a water inlet 11 fixedly connected to the top of the body 1, a drain pipe 12 fixedly connected to the bottom of the body 1, and a sewage pipe 13 fixedly connected to the bottom of the body 1. A heating element is provided inside the body 1. Water can enter through the water inlet 11, and water can be drained and sewage discharged through the drain pipe 12 and the sewage pipe 13, respectively.

[0026] A control mechanism is provided on the surface of the device body 1. The control mechanism includes a mounting plate 2, which is fixedly connected to the surface of the device body 1. A controller 21 is mounted on the surface of the mounting plate 2. A buzzer 22 is fixedly mounted on the top of the device body 1. A fixing rod 23 is fixedly connected to the inner wall of the device body 1. A movable plate 24 is movably connected to the surface of the fixing rod 23. A connecting rod 25 is fixedly connected to the lower surface of the movable plate 24. A float 26 is fixedly connected to the bottom end of the connecting rod 25. A first fixing plate 27 is fixedly connected to the surface of the fixing rod 23. A first pressure sensor 28 is fixedly mounted on the lower surface of the first fixing plate 27. A first pressure sensor 28 is fixedly mounted on the lower surface of the first fixing plate 27. A second fixed plate 29 is connected, and a second pressure sensor 210 is fixedly installed on the upper surface of the second fixed plate 29. Through the setting of the float 26, in conjunction with the function of the first pressure sensor 28 and the second pressure sensor 210, when the float 26 moves under the action of the water level and the movable plate 24 comes into contact with the first pressure sensor 28 or the second pressure sensor 210, the water level in the vessel body 1 can be monitored. It can also control the drain pipe 12 and the sewage pipe 13 through the mounting plate 2 to drain and replenish water in the vessel body 1, thereby ensuring that the water level is within a safe range, which is conducive to ensuring the safety of the low temperature heater.

[0027] Furthermore, the fixing rods 23 are fixedly connected to the body 1 in two sets, and both sets of fixing rods 23 are movably connected to the movable plate 24. By setting the fixing rods 23, the movement of the movable plate 24 can be limited, thereby ensuring the stability of the movement of the movable plate 24 and the float 26 under the action of water level.

[0028] Furthermore, one end of the connecting rod 25 is fixedly connected to the movable plate 24, and the other end of the connecting rod 25 is fixedly connected to the float 26. The connecting rod 25 moves inside the second fixed plate 29. The movable plate 24 and the float 26 are connected by the connecting rod 25, so that when the float 26 rises and falls under the action of the water level, the connecting rod 25 can drive the movable plate 24 to move accordingly under the action of the float 26.

[0029] Furthermore, the surface of the mounting plate 2 is provided with a mounting mechanism, which includes a connecting plate 3. The connecting plate 3 is fixedly connected to the surface of the controller 21. A positioning block 31 is fixedly connected to the end of the connecting plate 3 away from the controller 21. A positioning groove 32 is opened on the inner side of the mounting plate 2. A plug rod 33 is movably connected to the inner side of the mounting plate 2. A pull plate 34 is fixedly connected to the surface of the plug rod 33. A slot 35 is opened on the inner side of the positioning block 31. A spring 36 is fixedly connected to the surface of the pull plate 34. Through the movement of the plug rod 33, the plug rod 33 and the slot 35 can be inserted and separated, thereby fixing and releasing the positioning block 31, which facilitates the replacement of the controller 21.

[0030] Furthermore, the positioning blocks 31 are fixedly connected to the connecting plate 3 in two sets, the positioning grooves 32 are opened in two sets on the inner side of the mounting plate 2, and the insertion rods 33 are movable in four sets on the inner side of the mounting plate 2. By setting the positioning blocks 31 and opening the positioning grooves 32, the controller 21 can be positioned on the mounting plate 2, which can ensure the accuracy of the controller 21 installation and make the installation of the controller 21 more convenient.

[0031] Furthermore, two sets of slots 35 are provided on the inner side of the positioning block 31. One end of the spring 36 is fixedly connected to the mounting plate 2, and the other end of the spring 36 is fixedly connected to the pull plate 34. By setting the spring 36, the pull plate 34 can be reset, thereby enabling the insertion of the rod 33 and the slot 35, which facilitates the fixing of the positioning block 31.

[0032] Working principle: When the water level in the container 1 changes, the float 26 will change position under the action of the water level, thereby enabling the connecting rod 25 to move inside the second fixed plate 29 under the action of the float 26, and enabling the movable plate 24 to move on the surface of the fixed rod 23. Through the movement of the movable plate 24, it comes into contact with the first pressure sensor 28 or the second pressure sensor 210. The first pressure sensor 28 and the second pressure sensor 210 can feed the signal back to the controller 21, so that the controller 21 can control the drain pipe 12 and the sewage pipe 13 to drain and replenish water. At the same time, the controller 21 controls the buzzer 22 to work, so that the buzzer 22 can remind the staff.

[0033] By pulling up the pull plate 34, the insertion rod 33 can move inside the mounting plate 2 under the action of the pull plate 34 and separate from the slot 35. At this time, the spring 36 is in a stretched state, which can release the limit on the positioning block 31. Then, the positioning block 31 can be pulled out from the positioning groove 32, thus removing the controller 21. When the controller 21 needs to be installed and used, the positioning block 31 is moved into the positioning groove 32, and then the pull plate 34 is released. The pull plate 34 will reset under the rebound action of the spring 36, and then the insertion rod 33 will reset and insert into the slot 35, thus fixing the positioning block 31 and completing the installation of the controller 21.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
