Description

Technical Field

[0001] The utility model relates to the technical field of gasifier thermocouples, in particular to an adjustable thermocouple for a gasifier. Background Art

[0002] The vaporizer is an environmentally friendly, energy-saving, clean burning appliance suitable for use by farmers in rural areas and towns. Thermocouples are commonly used temperature measuring elements in temperature measuring instruments. They directly measure temperature and convert temperature signals into thermoelectric potential signals, which are then converted into the temperature of the measured medium through electrical instruments. The appearance of various thermocouples often varies greatly depending on needs, but their basic structure is roughly the same. They are usually composed of main parts such as thermode, insulating sleeve protection tube and junction box, and are usually used in conjunction with display instruments, recording instruments and electronic regulators.

[0003] For example, the patent document with the announcement number CN 214702547 U discloses a high-temperature thermocouple for a gasifier, which includes a spherical connecting rod; a compensation wire, which is arranged in the spherical connecting rod; a thermocouple wire, which is arranged in the spherical connecting rod; a ceramic transition terminal, which is arranged in the spherical connecting rod, and the compensation wire and the thermocouple wire are both connected to the ceramic transition terminal; a mounting hole, which is opened at the top of the spherical connecting rod; a cover plate, which is movably sealed and installed in the mounting hole; two card slots, which are symmetrically opened on the inner wall of the mounting hole; the high-temperature thermocouple for a gasifier provided by the utility model has the advantages of simple installation of the thermocouple wire, reduced frequency of use of sealing components and sealing joints, and greatly reduced chance of leakage.

[0004] However, during actual use, due to the limitations of its own structure, this structure can only use fixed thermocouples inside the gasifier for temperature measurement operations, which can easily lead to continuous high-temperature measurement operations of the thermocouples, causing the equipment inside the equipment to be in continuous operation and rapid equipment aging. At the same time, the equipment cannot perform positioning and protection operations when the thermocouples are adjusted inside and outside the gasifier, and cannot meet daily use needs. Therefore, it is urgent to design an adjustable thermocouple for the gasifier to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide an adjustable thermocouple for a gasifier, so as to solve the problem that the existing structure proposed in the above background technology can only adopt a fixed thermocouple temperature measurement operation inside the gasifier during actual use due to its own structural limitations, which easily leads to continuous high-temperature measurement operation of the thermocouple, causing the equipment inside the equipment to be in a continuous operating state, and the equipment to age and wear out quickly. At the same time, the equipment cannot perform positioning and protection operations when the thermocouple is adjusted inside and outside the gasifier, and cannot meet daily use needs.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an adjustable thermocouple for a gasifier, comprising a mounting seal seat, a sealing groove being formed on a side surface of the mounting seal seat, a driving cover frame being fixedly connected to one side of the mounting seal seat, a first protective cover frame being fixedly connected to one end of the mounting seal seat, and a second protective cover frame being fixedly connected to the other end of the mounting seal seat;

[0007] Thermocouple body, the interior of the second protective cover frame is movably connected with the thermocouple body, and one side of the thermocouple body is fixedly connected with a driving bevel rack.

[0008] Preferably, both ends of the thermocouple body are fixedly connected with positioning sockets, and one end of the positioning socket is provided with a positioning rubber head.

[0009] Preferably, one end of the first protective cover frame and the second protective cover frame away from each other is fixedly connected to a sleeve cover, and one end of the sleeve cover is fixedly connected to a positioning cover.

[0010] Preferably, temperature measuring grooves are provided on four sides of the first protective cover frame and the second protective cover frame.

[0011] Preferably, an inner wall of the mounting seal seat is provided with a positioning inner ring.

[0012] Preferably, a driving motor is provided at one end of the driving cover frame, and a driving bevel gear is movably connected to the interior of the driving cover frame via the driving motor.

[0013] Preferably, the driving helical gear and the driving helical rack are adapted to each other.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The adjustable thermocouple for a gasifier, through the provision of an installation seal seat, a sealing groove, a drive cover frame, a first protective cover frame, a second protective cover frame, a thermocouple body, a drive bevel rack, a drive motor, and a drive bevel gear, can enable the equipment to perform rapid telescopic protection adjustment operations on the thermocouple in the gasifier. During actual use, the staff first seals the installation seal seat at the temperature measurement point of the gasifier through the sealing groove on the side, and then movably installs the thermocouple body inside the installation seal seat so that the drive bevel rack on the side of the thermocouple body is adaptively docked with the side of the drive cover frame, and the drive bevel gear inside the drive cover frame is engaged with the drive bevel rack. When the drive motor at one end of the drive cover frame is started daily to drive the drive bevel gear as a whole for rotational adjustment, the thermocouple body as a whole is driven to perform piston movement along the installation seal seat, quickly moving the thermocouple body back and forth inside the first and second protective cover frames at the front and rear ends of the installation seal seat, providing a closed protection operation for the thermocouple body outside the gasifier, facilitating rapid maintenance and reflecting the practicality of the equipment design.

[0016] The adjustable thermocouple for the gasifier further improves the overall use effect of the equipment by arranging an installation sealing seat, a first protective cover frame, a second protective cover frame, a thermocouple body, a positioning card seat, a positioning rubber head, a sleeve cover, a positioning cover, a temperature measuring groove and a positioning inner ring. In daily use, when the second protective cover frame performs a piston movement back and forth inside the installation sealing seat, the first protective cover frame and the second protective cover frame at both ends of the sealing seat are first installed to perform the overall cover protection of the thermocouple body, and the thermocouple body performs adaptive temperature measurement operations at the temperature measuring grooves on the sides of the first protective cover frame and the second protective cover frame. At the same time, the positioning card seats and the positioning rubber heads at both ends of the thermocouple body can be adaptively plugged into the sleeve cover and the positioning cover at one end of the first protective cover frame and the second protective cover frame away from each other for adaptive adjustment and positioning protection, thereby ensuring the stability of the thermocouple body in each adjustment, reflecting the comprehensiveness of the equipment design.

[0025] The thermocouple body 6 and the second protective cover frame 5 are internally movably connected with the thermocouple body 6, and a driving bevel rack 7 is fixedly connected to one side of the thermocouple body 6. Both ends of the thermocouple body 6 are fixedly connected with positioning holders 8, and one end of the positioning holder 8 is provided with a positioning rubber head 9.
