In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0024] like Figure 1 As shown, an embodiment of the present invention provides a negative pressure regulating device for a carbon roasting furnace, which includes: a frame 1 and a plate structure;
[0025] The insert structure includes an intermediate slotted shell 2, a first sliding plate 3, a second sliding plate 4, and a first lead screw 5. The upper end of the intermediate slotted shell 2 is movably connected to the frame 1 to allow the intermediate slotted shell 2 to move up and down relative to the frame 1. The intermediate slotted shell 2 has a first opening on its left side and a second opening on its right side. The first sliding plate 3 is inserted into the first opening, and the second sliding plate 4 is inserted into the second opening. The first lead screw 5 is rotatably disposed in the upper part of the internal space of the intermediate slotted shell 2. The threads at both ends of the first lead screw 5 are in opposite directions. One end of the first lead screw 5 passes through the first sliding plate 3, and the other end passes through the second sliding plate 4. The two ends of the first lead screw 5 are respectively threaded to the first sliding plate 3 and the second sliding plate 4.
[0026] The working process of the negative pressure regulating device for the carbon roasting furnace is as follows:
[0027] For a fire channel of a specific width, when using this negative pressure adjustment device, the first lead screw 5 can be rotated to drive the first slide plate 3 and the second slide plate 4 to move away from or closer to each other, thereby changing the width of the insert plate structure formed by the first slide plate 3, the intermediate groove shell 2 and the second slide plate 4, so that the width of the insert plate structure matches the width of the fire channel.
[0028] By using this negative pressure regulating device, the flexibility of the insert plate adaptation is improved, and the flue gas flow of flues with different widths can be adjusted.
[0029] Specifically, the openings on the left and right sides of the intermediate groove shell 2 serve as guides for the relative movement of the first sliding plate 3 and the second sliding plate 4.
[0030] Specifically, the first slide plate 3 and the second slide plate 4 are respectively provided with threaded through holes along the width direction of the plate surface, and the two ends of the first lead screw 5 are respectively threaded to the threaded through holes.
[0031] like Figure 1 As shown, in a specific embodiment, the middle part of the first lead screw 5 is mounted on the opposite inner side wall of the intermediate groove shell 2 via a bearing, and the end of the first lead screw 5 is fixedly connected to the first handwheel 6.
[0032] In this embodiment, specifically, the bearing housing is fixedly connected to the inner side wall of the central axis of the internal space of the intermediate groove shell 2, the bearing is installed in the bearing housing, and the middle part of the first lead screw 5 is interference-fitted with the inner ring of the bearing. The operator can rotate the first handwheel 6 to drive the first lead screw 5 to rotate, thereby changing the distance between the first slide plate 3 and the second slide plate 4.
[0033] like Figure 1 As shown, in a specific embodiment, a guide rod 7 is also included. The guide rod 7 is fixedly disposed in the lower part of the internal space of the intermediate groove shell 2. The first slide plate 3 is provided with a first guide hole 8, and the second slide plate 4 is provided with a second guide hole 9. One end of the guide rod 7 is slidably connected to the first guide hole 8, and the other end is slidably connected to the second guide hole 9.
[0034] In this embodiment, specifically, the middle part of the guide rod 7 passes through the center of the fixing block and is fixedly connected to the fixing block. The opposite side of the fixing block is fixedly connected to the opposite side wall at the central axis of the internal space of the intermediate groove shell 2, so that there is a gap between the guide rod 7 and the opposite side wall of the intermediate groove shell 2. The first guide hole 8 and the second guide hole 9 are both blind holes. The first guide hole 8 and the second guide hole 9 are opposite to each other. The two ends of the guide rod 7 are slidably connected to the first guide hole 8 and the second guide hole 9 respectively. The guide rod 7 provides auxiliary guidance for the sliding of the first slide plate 3 and the second slide plate 4, thereby improving the stability of the insert plate structure.
[0035] like Figure 1 As shown, in a specific embodiment, the lower end of the frame 1 is fixedly connected to the base 10, the base 10 is provided with a through groove 11, and the lower end of the intermediate groove shell 2 is slidably connected to the through groove 11.
[0036] In this embodiment, specifically, the size of the base 10 is larger than the lower end size of the frame 1, and the base 10 is placed on the upper end of the fire channel wall to improve the stability of the device.
[0037] Specifically, the length of the through groove 11 is slightly less than the sum of the horizontal widths of the intermediate groove shell 2, the first sliding plate 3, and the second sliding plate 4. The length of the first lead screw 5 is equal to the length of the through groove 11. When the first sliding plate 3 and the second sliding plate 4 are moved away from each other and the distance between them is the largest by rotating the first lead screw 5, the first sliding plate 3 will not detach from the first opening and the second sliding plate 4 will not detach from the second opening.
[0038] Specifically, the first lead screw 5 is located in the upper part of the internal space of the intermediate slot shell 2. During the process of the insert plate structure being lowered into the fire channel, the two ends of the first lead screw 5 will not interfere with the through slot 11.
[0039] Meanwhile, when the width of the matched insert structure is less than the length of the through groove 11, the excess gaps in the through groove 11 can be sealed with soil to prevent outside air from entering the fire channel through the through groove 11.
[0040] When the horizontal width of the insert structure is increased, the first slide plate 3 and the second slide plate 4 move away from each other, and the slide plates can crush the blocking soil.
[0041] like Figure 1 As shown, in a specific embodiment, a second lead screw 12 is also included. The lower end of the second lead screw 12 is rotatably connected to the upper end of the intermediate groove shell 2, the second lead screw 12 is threadedly connected to the frame 1, and the upper end of the second lead screw 12 is fixedly connected to the second handwheel 13.
[0042] like Figure 1 and Figure 3 As shown, in this embodiment, specifically, the upper end of the intermediate groove shell 2 is fixedly connected to the retaining ring 14, the lower end of the second lead screw 12 passes through the retaining ring 14 and is fixedly connected to the circular plate 15, the circular plate 15 abuts against the lower end face of the retaining ring 14, the lower end diameter of the second lead screw 12 is smaller than the inner diameter of the retaining ring 14, the second lead screw 12 can rotate relative to the retaining ring 14, and the circular plate 15 prevents the retaining ring 14 and the second lead screw 12 from separating from each other.
[0043] Specifically, the operator turns the second handwheel 13, which causes the second lead screw 12 to rotate and rise relative to the frame 1, thereby driving the insertion plate structure to rise and fall.
[0044] like Figure 2 As shown, in a specific embodiment, a winch 16 is also included. The winch 16 is fixedly installed on the upper end of the frame 1, and the wire rope of the winch 16 is connected to the upper end of the intermediate trough shell 2.
[0045] In this embodiment, specifically, the operator adjusts the speed and direction of the winch 16 through the controller, and drives the plate structure to rise and fall by winding and unwinding the wire rope.
[0046] like Figure 1 or Figure 2 As shown, in a specific embodiment, it also includes two handles 17, which are respectively fixedly connected to opposite sides of the base 10.
[0047] In this embodiment, the operator holds the two handles 17 and adjusts the direction of the base 10 to make the plate surface of the insert structure and the cross-section of the fire channel coincide, thus ensuring a better negative pressure adjustment effect.
[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
