Technical Field

[0001] The utility model relates to the field of bentonite processing, in particular to a bentonite drying kiln sealing mechanism. Background Art

[0002] Bentonite is a clay rock with montmorillonite as the main mineral component. It has very strong adsorption, wetting, suspension, and bonding properties. It has a wide range of applications and is widely used in chemical, metallurgical, steel, papermaking, petroleum and other industries. It can be used as a stabilizer, suspending agent, purification and decolorization agent, binder, catalyst, etc. Due to its wide range of uses, it is called "all-purpose soil". Montmorillonite is a widely used natural mineral material. Due to the water absorption characteristics of bentonite itself, it is often necessary to use a drying kiln to dry the bentonite during the processing process. During the drying process, it is necessary to ensure that the inside of the drying kiln is in a sealed state.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0032] like Figures 1 to 5 As shown, a bentonite drying kiln sealing mechanism includes a fixed plate 1, which is connected to a support frame 2 through a connecting rod 101 installed on the bottom surface, and a fixing ring 102 is connected to the surface of the fixed plate 1, and a screw 3 threadedly connected to the inner side of the fixing ring 102 can adjust the position of a connecting plate 4 at one end by cooperating with the fixing ring 102, and a card groove 401 is provided on the inner side of the connecting plate 4 for easy limiting, and a buffer component 5 fixed on the surface of the connecting plate 4 is provided with a groove 501, and a telescopic member 504 sliding inside the groove 501 is used to fix the sealing member 6, and a sealing gasket 601 on one side surface of the sealing member 6 can be attached to the kiln head of the drying kiln for sealing, and a sealing strip 7 connected to the inner side of the sealing member 6 can cooperate with the sealing gasket 601 to further seal the kiln head, thereby improving the sealing effect.

[0033] Fixing bolts 201 are arranged at both ends of the surface of the support frame 2 .

[0034] Through the above technical solution, the support frame 2 can be fixed at any position by using the fixing bolts 201, so that the support frame 2 can be easily disassembled and assembled.

[0035] The rotation of the screw rod 3 is controlled by a knob 301 installed at one end, and the rotation enables a rotating member 302 installed at the other end of the screw rod 3 to rotate inside the connecting plate 4 with the cooperation of a second short spring 303 .

[0036] Through the above technical solution, the control of the knob 301 is utilized to ensure that the screw rod 3 can drive the rotating member 302 to rotate, thereby pushing the connecting plate 4 to adjust the position, thereby avoiding excessive pressure on the kiln head to cause damage to the kiln head.

[0037] The rotating member 302 is connected to the clamping block 322 via an internal short spring 1 321 , so that the clamping block 322 sliding inside the rotating member 302 can be clamped on the inner side of the clamping slot 401 .

[0038] Through the above technical solution, the rotating member 302 is limited by the engagement between the block 322 and the slot 401 to prevent the connecting plate 4 from moving due to the self-rotation of the rotating member 302, so that the sealing mechanism can perform a stable sealing operation after adjustment.

[0039] The connection plate 4 is provided with a limiting rod 402 which slides on the surface of the fixing plate 1 , and a stopper 403 located at the other side of the fixing plate 1 is provided at one end of the limiting rod 402 away from the connection plate 4 .

[0040] Through the above technical solution, under the limitation of the stopper 403, when the position of the connecting plate 4 is adjusted by the rotation of the screw rod 3, its position can be limited to prevent it from rotating together with the screw rod 3.

[0041] A groove 501 is fixed on the surface of the connecting plate 4, and a buffer spring 1 502 is arranged on its side to connect the moving plate 503, so that the moving plate 503 can slide inside the groove 501, so that the telescopic part 504 on the surface of the moving plate 503 can drive the sealing part 6 to move. At the same time, the buffer spring 2 505 located on the surface of the groove 501 and the telescopic part 504 is fixed between the connecting plate 4 and the sealing part 6.

[0042] Through the above technical solution, the buffer spring 2 505 located outside the groove 501 and the telescopic member 504 can cooperate with the buffer spring 1 502 to buffer the position of the seal 6, and the kiln head position will not be too tight when the screw 3 is used to adjust the connecting plate 4.

[0043] When in use, when the user uses the bentonite drying kiln sealing mechanism, the support frame 2 of the mechanism is placed above the drying kiln, the entire sealing mechanism is fixed to the surface of the drying kiln by the fixing bolts 201, and the stopper 403 is pulled to one side. Under the elastic force of the short spring 2 303, the block 322 can be separated from the slot 401, so that the rotating member 302 can rotate inside the connecting plate 4, and the knob 301 is turned to make the screw 3 drive the rotating member 302 to rotate, so that the connecting plate 4 is pushed by the rotating member 302 to move and adjust the spacing, so that the sealing member 6 can fit on the surface of the kiln head of the drying kiln, and under the elastic force of the buffer spring 1 502 and the buffer spring 2 505 of the buffer assembly 5, the sealing member 6 will not press the kiln head too tightly, so that the sealing strip 7 and the sealing gasket 601 can both fit closely to the kiln head, thereby improving the sealing effect.
