Description

Technical Field

[0001] The utility model belongs to the technical field of temperature sensor protection, in particular to a temperature sensor protection structure for viscous material production. Background Art

[0002] With the rapid development of the food industry, the requirements for food quality and safety are becoming increasingly stringent. Temperature control, as a key link in ensuring the quality of food processing, is of self-evident importance. In the processing of jams, sauces, and other viscous foods, accurate temperature measurement is crucial to the taste, nutritional preservation, and food safety of the products. In food production, temperature sensors need to be installed on the production tanks at all times to keep track of the material temperature. However, due to the viscosity of the material, it is easy for it to adhere to the sensing probe of the temperature sensor, resulting in inaccurate measurements and frequent maintenance. In addition, due to the insulating properties of the adhered material, it may also cause a delay in the response of the temperature sensor, affecting the real-time monitoring effect. At this time, in order to maintain the normal operation of the sensor, frequent shutdowns and cleaning are often required, which not only increases maintenance costs but also reduces production efficiency.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] As shown in the figure, a temperature sensor protection structure for viscous material production includes a temperature sensor 1. A connector 2 is screwed to the upper side of the sensing probe 11 at the bottom of the temperature sensor 1. A protective sleeve 3 is provided at the bottom of the connector 2 and is sleeved on the outside of the sensing probe 11. The bottom of the protective sleeve 3 is located below the sensing probe 11 and is sealed. A plurality of arc-shaped through grooves 31 are evenly distributed along the circumference and arranged vertically are provided on the protective sleeve 3. In this embodiment, the connector 2 is pressed against the inner wall of the food processing tank, providing a mounting position for the protective sleeve 3 while also sealing the mounting position of the temperature sensor 1 on the tank body; when measuring the temperature of viscous materials such as jam in the food processing tank, the protective sleeve 3 protects and isolates the sensing probe 11 of the temperature sensor 1 to avoid direct contact between the sensing probe 11 and the material, which may cause contamination or damage to the sensing probe 11 when the viscous material adheres, thereby affecting the accuracy of the temperature measurement. At the same time, since a plurality of arc-shaped grooves 31 are provided on the outside of the protective sleeve 3, the material flow is facilitated and the accumulation on the surface of the protective sleeve 3 is reduced; the temperature measurement operation of the viscous material is achieved by heat conduction through the protective sleeve 3.

[0027] The connector 2 is a square structure with a threaded hole 21 in the middle. The connector 2 is screwed to the upper side of the sensor probe 11 through the threaded hole 21. Restriction grooves 23 in opposite directions are provided on the outer walls of the connector 2 on both sides. Restriction posts 33 are horizontally fixed to the upper side of the protective sleeve 3 corresponding to the restriction grooves 23, and the restriction posts 33 are clamped in the restriction grooves 23. In this embodiment, an external thread is provided on the upper side of the sensor probe 11, and a positioning plate 12 is provided on the upper side of the external thread of the temperature sensor 1. During installation, the temperature sensor 1 is inserted into the container, and the end is screwed to the top of the container through the sensor probe 11. The connector 2 with the protective sleeve 3 clamped is then screwed to the sensor probe 11 until the connector 2 and the positioning plate 12 clamp the top side plate of the container. This not only seals the installation location of the temperature sensor 1, but also ensures the installation stability of the temperature sensor 1.

[0028] The bottom of the connector 2 is provided with an annular groove 22 coaxially arranged with the threaded hole 21. The upper end surface of the protective sleeve 3 is provided with an annular positioning edge 32, the inner ring of which is aligned with the inner wall of the protective sleeve 3. The outer ring of the annular positioning edge 32 is aligned with the outer wall of the protective sleeve 3. The annular positioning edge 32 is inserted into the annular groove 22, and the depth of the annular groove 22 is greater than the height of the annular positioning edge 32. The limiting groove 23 is a hook-shaped structure and is connected to the annular groove 22. The bottom of the vertical section on one side of the limiting groove 23 is open, and a retractable limiting block 4 is provided in the connector 2 at the corresponding vertical section on the other side. When the limiting post 33 is engaged in the vertical section on the other side, the limiting block 4 is arranged on the upper side of the limiting post 33 to press against the limiting post 33. In this embodiment, the limiting post 33 is fixed to the annular positioning edge 32.

[0029] A notch 24 is provided on the upper side of the connecting piece 2 corresponding to the limit block 4, a blocking block 5 is fixedly connected to the notch 24, and a through groove 25 is provided at the bottom of the notch 24 corresponding to the limit block 4, and limiting grooves 26 connected to the through grooves 25 are provided on both sides of the through groove 25, and the bottom end of the limiting groove 26 is sealed, and limiting ears integrally formed with the limit block 4 are horizontally fixed at the limiting grooves 26 on both sides of the top of the limit block 4 corresponding to the limit grooves 26, and the limiting ears are located in the corresponding limiting grooves 26, and the limit block 4 is guided and limited by the movement of the limiting ears in the limiting grooves 26 to prevent the limit block 4 from disengaging from the through groove 25. A spring is provided between the top of the limit block 4 and the blocking block 5, and when the limiting column 33 moves to the bottom of the limit block 4 and is tightened by the limit block 4, the spring is in a compressed state. In this embodiment, when the limiting post 33 moves along the opening of the vertical section on one side of the limiting groove 23 toward the vertical section on the other side, the limiting post 33 pushes up the limiting block 4, compressing the spring until the limiting post 33 snaps into place. The limiting block 4, under the action of the spring, presses against the limiting post 33. In this embodiment, a countersunk hole 51 is provided on the upper side of the blocking block 5. A screw is provided in the countersunk hole 51 to secure the blocking block 5 to the notch 24. When the connecting member 2 presses against the inner wall of the tank, the countersunk hole 51 and the end face of the screw are concealed to prevent material from entering.

[0030] The bottom of the limiting block 4 is provided with an inclined surface 41 toward the vertical section with an opening at the bottom, so that the limiting block 4 can be lifted up by the limiting column 33 when the protective sleeve 3 is moved manually.

[0031] An anti-stick coating is applied on the surface of the protective sleeve 3. In this embodiment, the anti-stick coating is a smooth food-grade coating, specifically made of silicone, which facilitates material flow and reduces adhesion.

[0032] The protective sleeve 3 is made of food-grade stainless steel.

[0033] A gap is provided between the interior of the protective sleeve 3 and the sensing probe 11 to prevent the protective sleeve 3 from directly rubbing against the sensing probe 11 and causing wear to the sensing probe 11 when the protective sleeve 3 is disassembled.

[0034] The working process of this embodiment is as follows:

[0035] During installation, the temperature sensor 1 is screwed to the top of the container through the sensor probe 11, and the connecting piece 2 is tightened. The top side plate of the container is clamped by the positioning plate 12 and the connecting piece 2, which on the one hand seals the installation position of the temperature sensor 1, and on the other hand ensures the installation stability of the temperature sensor 1; the annular positioning edge 32 of the protective sleeve 3 is inserted into the annular groove 22 of the connecting piece 2, and the limiting column 33 enters the limiting groove 23 from the vertical section on one side of the limiting groove 23 with an open end, and moves along the trajectory of the limiting groove 23. During the movement, the limiting block 4 is lifted up and enters the vertical section on the other side of the limiting groove 23. Under the action of the spring, the limiting block 4 presses the limiting column 33 to limit the position, and finally realizes the installation of the protective sleeve 3.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
