Description

Technical Field

[0001] The utility model relates to the technical field of metal detection, in particular to a constant temperature water bath device for metal detection. Background Art

[0002] A constant-temperature water bath for metal detection is a device that precisely controls and maintains water temperature. It plays a crucial role in metal detection experiments and industrial inspection processes. Its principle is based on thermal equilibrium. Water is heated by a heating element (such as a heating tube) while a temperature sensor (such as a high-precision thermometer or thermistor) monitors the water temperature in real time. When the water temperature falls below the set point, the heating element activates, raising the temperature. When the water temperature reaches or exceeds the set point, the heating element stops heating, and the device's thermal insulation (such as insulation material) maintains the water temperature.

[0003] Prior art, such as publication number CN219463456U, provides a heating and thermostatic device comprising a water bath mechanism, wherein a stirring mechanism for stirring water is mounted at the bottom of the water bath mechanism, a sealing mechanism for sealing the water bath mechanism is mounted at the top of the water bath mechanism, and a control mechanism is mounted on one side of the water bath mechanism; the water bath mechanism comprises an outer pot, an electric heating plate for heating is mounted on the inner bottom wall of the outer pot, and an inner pot for holding water is mounted on the top of the electric heating plate; the stirring mechanism comprises a mounting seat, and a drive motor is mounted in the middle of the inner bottom wall of the mounting seat. In this heating and thermostatic device, a connecting column is driven to rotate by a drive shaft on the drive motor, and the connecting column drives a stirring blade via a connecting rod to stir the water in the inner pot, thereby evenly heating the water in the inner pot during the heating process, thereby evenly heating the metal parts and avoiding affecting the detection effect.

[0004] In this scheme, a drive shaft on a motor drives a connecting column to rotate. Simultaneously, the connecting column drives a stirring blade via a connecting rod to stir the water in the inner pot. This ensures uniform heating of the water in the inner pot, thereby ensuring uniform heating of the metal parts and preventing any impact on detection results. However, because temperature control is achieved through heated water, the heating rate is relatively slow compared to some rapid heating devices that directly heat metal specimens. Rapidly increasing the temperature from room temperature to a higher set point can take a long time; for example, increasing the temperature from 20°C to 80°C can take 30 minutes or even longer. Furthermore, due to the large specific heat capacity of water, the device's response to temperature changes has a certain lag during temperature adjustment, which can affect experimental efficiency, especially in experiments requiring frequent temperature changes. Therefore, we propose a constant temperature water bath device for metal detection. Utility Model Content

[0005] The purpose of the utility model is to provide a constant temperature water bath device for metal detection. The constant temperature water bath device for metal detection solves the problem that during the temperature adjustment process, due to the large specific heat capacity of water, the equipment has a certain lag in responding to temperature changes, which may affect the efficiency of the experiment, especially in experiments that require frequent temperature changes.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A constant temperature water bath device for metal detection, comprising a bath tub, a liquid storage tub being fixedly connected to the bottom of the bath tub, and a temperature regulating mechanism being arranged inside the liquid storage tub;

[0008] The temperature control mechanism includes a partition, which is slidably connected to the inner wall of the liquid storage barrel and is used to divide the space of the liquid storage barrel. A heating pipe is fixedly connected to the bottom of the inner wall of the liquid storage barrel. A cylinder is fixedly connected to the bottom of the liquid storage barrel, and the telescopic end of the cylinder extends to the interior of the liquid storage barrel and is fixedly connected to the bottom of the partition. A liquid injection ring is fixedly connected to the bathing barrel, and the liquid injection ring is connected to the interior of the liquid injection ring through a connecting pipe. The bathing barrel is connected to the interior of the liquid storage barrel through a connecting hole.

[0009] Preferably, a sealing ring is fixedly connected to the position where the cylinder is connected to the bottom of the liquid storage barrel, and the number of the connecting pipes is three and distributed in a ring array.

[0010] Preferably, the injection ring is provided with a plurality of injection holes at a position inside the bath tub, which are distributed in a circular array, and the injection holes are arranged at an inclination.

[0011] Preferably, the bottom of the bath tub is funnel-shaped, and a filter is fixedly connected to the bottom of the bath tub below the connecting hole.

[0012] Preferably, the inner wall of the connecting hole is rotatably connected to a worm gear, and the top of the worm gear is connected to three groups of scrapers, which are distributed in a ring array and fit the inner wall of the bathtub.

[0013] Preferably, the outer wall of the scraper is connected to a stirring blade, and the inner wall of the stirring blade is provided with a through hole.

[0014] Preferably, a support frame is connected to the inner wall of the bath tub at a position above the funnel-shaped area, and a support mesh plate is connected to the top of the support frame.

[0015] By means of the above technical solution, the present invention provides a constant temperature water bath device for metal detection, which has at least the following beneficial effects:

[0016] 1. The utility model arranges a liquid storage barrel at the bottom of the bath tub and divides the bath tub into two areas by a partition. The area above the partition is a low-temperature area, and the area below the partition is a high-temperature area heated by a heating pipe. When the temperature inside the bath tub needs to be adjusted, the partition is directly driven down by the expansion and contraction of the cylinder, so that the pressure in the high-temperature area of ​​the bath tub below the partition is increased, so that the hot water in the high-temperature area below is squeezed into the connecting pipe and injected into the bath tub through the liquid injection ring. Moreover, due to the sinking of the partition, the low-temperature area of ​​the bath tub above the partition is under negative pressure, so that the water inside the bath tub is sucked into the liquid storage barrel through the connecting hole. The water temperature can be quickly increased by directly exchanging the water, thereby avoiding the lag in the response of the equipment to the temperature change due to the large specific heat capacity of water, which affects the efficiency of subsequent detection.

[0017] 2. The utility model evenly distributes the injection holes on the injection ring so that hot water can be injected into the bath tub relatively evenly. The injection holes are tilted so that the injected hot water is injected into the bath tub in an oblique manner, causing the water in the bath tub to rotate and stir, so that the water in the bath tub is heated evenly.

[0024] 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.

[0025] Example 1

[0026] Constant temperature water bath device for metal detection, such as Figure 1 、 Figure 2 As shown, it includes a bathing tub 1, the bottom of which is fixedly connected to a liquid storage tub 2, a temperature control mechanism 3 is arranged inside the liquid storage tub 2, and the temperature control mechanism 3 includes a partition 31, which is slidably connected to the inner wall of the liquid storage tub 2 and is used to divide the space of the liquid storage tub 2, and a heating pipe 32 is fixedly connected to the bottom of the inner wall of the liquid storage tub 2, which is vortex-shaped, increasing the contact area with the water body and improving the heating efficiency, and a cylinder 33 is fixedly connected to the bottom of the liquid storage tub 2, and the telescopic end of the cylinder 33 extends to the interior of the liquid storage tub 2 and is fixedly connected to the bottom of the partition 31, and a liquid injection ring 34 is fixedly connected to the bathing tub 1, and the liquid injection ring 34 is connected to the interior of the liquid injection ring 34 through a connecting pipe 36, and the bathing tub 1 is connected to the interior of the liquid storage tub 2 through a connecting hole 35, and a sealing ring is fixedly connected to the position where the cylinder 33 is connected to the bottom of the liquid storage tub 2, and there are three connecting pipes 36, which are distributed in a ring array.

[0027] In this embodiment, a liquid storage barrel 2 is provided at the bottom of the bath tub 1 and is divided into two areas by a partition 31. The area above the partition 31 is a low-temperature area, and the area below the partition 31 is a high-temperature area heated by the heating tube 32. When the temperature inside the bath tub 1 needs to be adjusted, the partition 31 is directly driven to sink by the expansion and contraction of the cylinder 33, so that the pressure in the high-temperature area of ​​the bath tub 1 below the partition 31 increases, so that the hot water in the high-temperature area below is squeezed into the connecting pipe 36 and injected into the bath tub 1 through the liquid injection ring 34. Moreover, due to the sinking of the partition 31, the low-temperature area of ​​the bath tub 1 above the partition 31 is under negative pressure, so that the water inside the bath tub 1 is sucked into the liquid storage barrel 2 through the connecting hole 35. The water temperature can be quickly increased by directly exchanging the water.

[0028] Example 2

[0029] like Figure 4 As shown, the injection ring 34 is located inside the bath tub 1 and has a plurality of injection holes 341 distributed in a circular array, and the injection holes 341 are arranged at an angle.

[0030] In this embodiment, the hot water is injected into the bath tub 1 relatively evenly by evenly distributing the injection holes 341 on the injection ring 34, and the tilted injection holes 341 allow the injected hot water to be injected into the bath tub 1 in an oblique manner, causing the water in the bath tub 1 to rotate, thereby stirring the water and heating it evenly.

[0031] Example 3

[0032] like Figure 2 、 Figure 3 As shown, the bottom of the bath tub 1 is funnel-shaped, and a filter screen 351 is fixedly connected to the bottom of the bath tub 1 below the connecting hole 35, which can intercept impurities in the water and prevent impurities from entering the liquid storage barrel 2. The inner wall of the connecting hole 35 is rotatably connected to a worm gear 352, and the top of the worm gear 352 is connected to three groups of scrapers 353, which are distributed in a circular array and fit the inner wall of the bath tub 1. The outer wall of the scraper 353 is connected to a stirring blade 354, and the inner wall of the stirring blade 354 is provided with a through hole. The inner wall of the bath tub 1 is connected to a support frame 371 at a position above the funnel-shaped area, and the top of the support frame 371 is connected to a supporting mesh plate 37.

[0033] In this embodiment, when water flows through the connecting hole 35, the potential energy of the flowing water will drive the worm gear 352 to rotate, thereby driving the scraper 353 connected to the worm gear 352 to rotate, so as to facilitate the scraping of some precipitated impurities in the funnel-shaped area at the bottom of the bath tub 1, to avoid the formation of stubborn scale, which increases the difficulty of later cleaning. When the scraper 353 rotates, it will also drive the stirring blade 354 to rotate, further enhancing the stirring of the water body, so that the temperature distribution of the water body is more uniform.

[0034] When the constant temperature water bath device for metal detection of the present invention is in use, when the temperature inside the bath tub 1 needs to be adjusted, the partition 31 is driven to sink directly by the expansion and contraction of the cylinder 33, so that the pressure in the high temperature area of ​​the bath tub 1 below the partition 31 increases, so that the hot water in the high temperature area below is squeezed into the connecting pipe 36 and injected into the bath tub 1 through the injection ring 34. Moreover, due to the sinking of the partition 31, the low temperature area of ​​the bath tub 1 above the partition 31 is under negative pressure, so that the water inside the bath tub 1 is sucked into the liquid storage barrel 2 through the connecting hole 35. The water temperature can be quickly increased by directly exchanging the water body, and by evenly distributing the injection holes 341 on the injection ring 34, The hot water is injected into the bath tub 1 relatively evenly, and the tilted liquid injection hole 341 allows the injected hot water to be injected into the bath tub 1 in an oblique manner, causing the water in the bath tub 1 to rotate, thereby stirring the water in the bath tub 1 so that the water is heated evenly. When water flows through the connecting hole 35, the potential energy of the flowing water will drive the worm gear 352 to rotate, thereby driving the scraper 353 connected to the worm gear 352 to rotate, so as to facilitate the scraping of some precipitated impurities in the funnel-shaped area at the bottom of the bath tub 1, to avoid the formation of stubborn scale, which increases the difficulty of later cleaning. When the scraper 353 rotates, it will also drive the stirring blade 354 to rotate, further enhancing the stirring of the water body, so that the temperature distribution of the water body is more uniform.
