[0002] The furnace pit in a metal heat treatment workshop usually refers to a pit-shaped structure used to accommodate the furnace body during the metal heat treatment process. The furnace pit is usually constructed with refractory and thermal insulation materials to reduce heat loss and improve energy efficiency.

[0003] The furnace pit safety protection structure in the metal heat treatment workshop is a safety device specially designed to address potential dangerous factors such as high temperature, harmful gases and dust during the heat treatment process. It ensures that workers can operate safely in harsh working environments while reducing the risk of accidents.

[0004] In order to effectively remove harmful gases, an exhaust device is usually installed at the bottom of the furnace pit cover. However, when the furnace pit cover is opened, the angle and position of the exhaust device may change, causing the exhaust device to be exposed to the outside. This change makes it inevitable that debris and oxidized residues will fall into the exhaust end of the exhaust device. If these residues cannot be cleaned in time, it will not only affect the normal operation of the exhaust device, but also may bring safety hazards. Therefore, a furnace pit safety protection structure for a metal heat treatment workshop is proposed to address the above problems. Utility Model Content

[0025] A furnace pit safety protection structure for a metal heat treatment workshop includes a fixed platform 1, one side of the top of the fixed platform 1 is fixedly connected to a support column 2, the top of the support column 2 is fixedly connected to a protection component 3, the surface of the protection component 3 is rotatably connected to a protection cover 4, the outer side of the protection component 3 is rotatably connected to two connecting sleeves 41, the two connecting sleeves 41 correspond to each other, the surface of the connecting sleeve 41 is fixedly connected to the outer side of the protection cover 4, the protection component 3 includes a sealing tube 31, one end of the sealing tube 31 is threadedly connected to an exhaust pipe 32, the front end surface of the sealing tube 31 is provided with an exhaust groove 33, the inner wall of the exhaust groove 33 is fixedly connected to a filter plate 34, a cleaning component 36 is provided on the inner side of the sealing tube 31, the front end surface of the sealing tube 31 is provided with a connecting groove 37, the cleaning component 36 includes a reciprocating screw rod 361, the reciprocating screw rod 361 is rotatably arranged inside the sealing tube 31, one end of the reciprocating screw rod 361 is fixedly connected to a runner 362, two runners 362 are provided, and the outer diameter of the runner 362 is equal to the inner diameter of the sealing tube 31 The second end of the first connecting rod 364 is fixedly connected to the first connecting rod 365, and the first connecting rod 364 is slidably engaged with the connecting groove 37. The angle between the first connecting rod 364 and the second connecting rod 365 is 90 degrees. One end of the second connecting rod 365 is fixedly connected to a cleaning brush 366. The cleaning brush 366 is made of heat-resistant metal material. The inner side of the cleaning brush 366 slides with the surface of the filter plate 34. The surface of the filter plate 34 and the surface of the sealing tube 31 are on the same horizontal line. In this way, the reciprocating motion of the cleaning brush 366 automatically removes debris and oxidation residues on the filter plate 34, reducing the need for manual cleaning and ensuring the normal operation of the exhaust operation.

[0026] As a further implementation of this solution, one end of the inner wall of the sealing tube 31 is fixedly connected to two equidistantly arranged mounting plates 5, and the mounting plates 5 are rotatably connected to the reciprocating screw 361. This arrangement provides stable support and ensures the stability of the rotation of the reciprocating screw 361.

[0027] As a further implementation scheme of this scheme, an anti-slip groove 371 is opened on the inner side of the connecting groove 37, and folding plates 372 are fixedly connected at both ends of the connecting groove 37. The outer side of the folding plate 372 slides with the inner wall of the anti-slip groove 371. The two folding plates 372 are located on the same horizontal line, and one end of the folding plate 372 is fixedly connected to the connection. The folding plate 372 is made of carbon fiber composite material and has good heat resistance. This arrangement can ensure the sealing effect of the connecting groove 37 and prevent debris and residue from falling into the threaded groove of the reciprocating screw rod 361.

[0028] Working process: The fixed platform 1 is used to be installed and fixed on the upper surface of the furnace pit, the protective cover 4 corresponds to the center of the furnace pit, one end of the exhaust pipe 32 is connected to the exhaust end of the external exhaust fan through a hose, and the toxic gas emitted from the furnace pit is extracted through the exhaust slot 33 and the filter plate 34. When the air flow passes through the runner 362, it will apply a torque to the runner 362, so that the runner 362 starts to rotate, and the runner 362 drives the reciprocating screw 361 to rotate synchronously. The reciprocating screw 361 converts the rotational motion into the reciprocating linear motion of the connecting seat 363. When the connecting seat 363 moves, it drives the first connecting rod 364 to move. The first connecting rod 364 is connected to the connecting seat 363. The connecting rod 364 drives the cleaning brush 366 to move synchronously through the second connecting rod 365. The cleaning brush 366 reciprocates on the surface of the filter plate 34 to clean the debris and oxidation residue attached to the surface of the filter plate 34. The mounting plate 5 provides stable support for the rotation of the reciprocating screw rod 361. The movement of the first connecting rod 364 will also drive the connecting block 373 to move synchronously. The connecting block 373 drives the folding plates 372 at both ends to retract and retract. The folding plates 372 can ensure the sealing effect of the connecting groove 37, prevent debris and residue from falling into the threaded groove of the reciprocating screw rod 361, and ensure the normal operation of the connecting seat 363.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
