Description
Technical Field
[0001] The utility model relates to the technical field of denitration catalyst cutting, in particular to a denitration catalyst positioning and cutting device. Background Art
[0002] Denitrification catalyst refers to a catalyst that causes the reducing agent to selectively react with nitrogen oxides in flue gas at a certain temperature in a selective catalytic reduction reaction. Denitrification catalyst is often used in industry to denitrify flue gas in an air reactor to achieve the effect of purifying the air. Under normal circumstances, the denitrification catalyst is a columnar, long strip solid. During the production process of the denitrification catalyst, it needs to be cut using a cutting device to adapt to different reaction requirements.
[0003] At present, most of the cutting devices for denitration catalysts include a frame, a material conveyor belt, a material connection belt and a lifting cutting saw blade. The material conveyor belt and the material connection belt are spaced at both ends of the frame along the length direction. The material connection belt moves in the same direction and speed as the material conveyor belt. The lifting cutting saw blade is set on the frame and located above the space between the material conveyor belt and the material connection belt. When cutting the denitration catalyst, the denitration catalyst with the cut is first placed on the material conveyor belt. The material conveyor belt transports the denitration catalyst to pass under the lifting cutting saw blade. After the passing end of the denitration catalyst is overlapped on the material connection belt, it continues to be transported forward until the passing section of the denitration catalyst reaches the required size. The transmission of the material conveyor belt and the material connection belt is suspended, and the lifting cutting saw blade moves downward to cut the denitration catalyst. After the cutting is completed, the lifting cutting saw blade is reset, and the material conveyor belt and the material connection belt continue to be transported. The above process is repeated to cut the next section of the denitration catalyst.
[0004] Regarding the above-mentioned related technologies, when the cutting device is cutting the denitration catalyst, the denitration catalyst is moving along the discharge direction at the same time. Since the extruded denitration catalyst material is relatively soft, the cut is easily damaged, which leads to defects that affect the cutting quality of the denitration catalyst.
[0005] Therefore, it is particularly important to design a denitration catalyst positioning and cutting device to solve the above-mentioned defects. Utility Model Content

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.
[0024] Example:
[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution:
[0026] A denitration catalyst positioning and cutting device comprises a conveyor frame 1, a material connection belt 2 and a feeding belt 3 are respectively installed at the front and rear ends of the conveyor frame 1, an adjusting frame 4 and an auxiliary frame 5 are respectively fixedly connected to the top of the conveyor frame 1 and located at the connection between the material connection belt 2 and the feeding belt 3, a first positioning plate 6 is installed at the left and right ends of the inner side of the adjusting frame 4, a second positioning plate 7 is respectively installed at the left and right ends of the inner side of the auxiliary frame 5, a cutting frame 8 is fixedly connected to the top of the conveyor frame 1 and located at the connection between the first positioning plate 6 and the second positioning plate 7, and a dust hood 9 is installed at the bottom of the conveyor frame 1 and located at the connection between the material connection belt 2 and the feeding belt 3.
[0027] First, support feet 101 are fixedly connected to the four corners of the bottom of the conveyor frame 1, baffles 102 are fixedly connected to the left and right ends of the front and rear sides of the conveyor frame 1, and motors 103 compatible with the receiving belt 2 and the conveyor belt 3 are installed on the front and rear ends of the left side of the conveyor frame 1. The conveyor frame 1 is supported by multiple sets of support feet 101, and the receiving belt 2 and the conveyor belt 3 are driven by the motor 103 to convey the denitrification catalyst. During the transportation process, the left and right sides of the top of the conveyor frame 1 are protected by the baffle 102.
[0028] Furthermore, the inner side of the adjusting frame 4 is rotatably connected to a bidirectional screw rod 401, and the left end of the bidirectional screw rod 401 is fixedly connected to the outer side of the adjusting frame 4 with an adjusting crank 402, and the top ends of the two groups of first positioning plates 6 are threadedly connected to the bidirectional screw rod 401 through a connecting seat 403. After the denitration catalyst is produced, the adjusting crank 402 is first shaken according to the width of the denitration catalyst to drive the bidirectional screw rod 401 to rotate, and the distance between the two groups of first positioning plates 6 is adjusted under the connection of the connecting seat 403, so that after the denitration catalyst is produced, the left and right sides thereof are limited by the two groups of first positioning plates 6.
[0029] Then, the top ends of the two groups of second positioning plates 7 are slidably connected to the auxiliary frame 5 through the slider 701, and the two groups of second positioning plates 7 are fixedly connected to the two groups of first positioning plates 6 through the connecting rod 702 respectively.

At the same time, when the first positioning plate 6 and the second positioning plate 7 position the denitration catalyst, multiple groups of first rollers 703 and second rollers 704 are used to assist in transportation.

[0032] Finally, a storage drawer 905 is slidably connected to the bottom of the storage box 903, and a blocking net is installed at the connection between the vacuum cleaner 904 and the storage box 903. Impurities entering the storage box 903 enter the storage drawer 905 under the blocking of the blocking net, and the storage drawer 905 can be pulled out for cleaning later.
[0033] In this embodiment, the implementation scenario is specifically as follows: after the denitration catalyst is produced, the crank handle 402 is first adjusted according to the width of the denitration catalyst to drive the bidirectional screw rod 401 to rotate, and the distance between the two groups of first positioning plates 6 is adjusted under the connection of the connecting seat 403, so that after the denitration catalyst is produced, the left and right sides thereof are limited by the two groups of first positioning plates 6, and under the connection of the connecting rod 702 and the sliding cooperation of the slider 701 and the auxiliary frame 5, the distance between the two groups of second positioning plates 7 is synchronously driven to be adjusted, so that after the denitration catalyst is cut, the left and right sides thereof can still be positioned, thereby avoiding the problem of easy damage at the incision, ensuring the cutting quality of the denitration catalyst, and the produced The denitrification catalyst is transported through the material connection belt 2. When the denitrification catalyst is transported to the connection between the material connection belt 2 and the feeding belt 3, the lifting seat 802 is lowered by the hydraulic cylinder 801, and the lifting seat 802 is stably driven to be lowered under the sliding cooperation of the slide groove 803, so that the denitrification catalyst is cut by the cutting wire 804. During the cutting process, the vacuum cleaner 904 is started, and the impurities at the incision are sucked into the dust suction chamber 901 under the action of suction, and then introduced into the storage box 903 through the connecting pipe 902, so as to avoid the accumulation of impurities at the cutting place to affect the cutting quality. The whole operation process is simple and convenient. Compared with the existing denitrification catalyst cutting device, the utility model can improve the cutting quality of the denitrification catalyst positioning cutting device through design.
