Abstract
Description
Technical Field
[0001] The utility model relates to a flue with an on-off control device, in particular to the structure of the flue with the on-off control device. Background Art
[0002] The potassium chloride production workshop consists of a processing system, drying equipment, and packaging system. The processing system uses carnallite as raw material to produce potassium chloride wet material. The moisture content of the potassium chloride wet material is approximately 9%. After the potassium chloride wet material is dried in the drying system, the potassium chloride product with a moisture content of less than 1% is obtained. The product is then sorted and packaged in the packaging system. The drying equipment typically uses a drying drum. During the drying process, the potassium chloride wet material is dried, generating dust containing fine potassium chloride particles. The dust needs to be recovered by a dust removal device.
[0003] Due to factors such as the different dust particle sizes and dust concentrations, as well as the need for equipment maintenance, existing dust removal devices are equipped with bag dust collectors and cyclone dust collectors at the same time. The bag dust collectors and cyclone dust collectors are connected to the transfer pipes set on the dust outlet of the drying system through two flues respectively. During dust removal, the flue connected to the bag dust collector is opened and the flue connected to the cyclone dust collector is cut off as needed, or the flue connected to the cyclone dust collector is opened and the flue connected to the bag dust collector is cut off, thereby switching between the bag dust collector and the cyclone dust collector for dust removal operations.
[0004] The existing method of connecting or cutting off the flue is to disconnect the flue and set a flange on the fracture. When one of the flues needs to be connected, the two sections of the flue are connected through a flexible connection. When one of the flues needs to be cut off, the flexible connection is removed and the blind plate is installed on the flange of the flue fracture with bolts.
[0005] When switching between bag-type and cyclone dust collectors, due to the large size and weight of the blind plate, the bolts connecting the blind plate to the flue must be removed first. Then, a crane must be used to lift and remove the blind plate. This process requires the coordinated efforts of numerous maintenance personnel, which can easily cause injuries and is time-consuming, labor-intensive, and inefficient, impacting normal production. Furthermore, excessive removal of the fixing bolts can damage the bolts and flexible connections, shortening their service life.
[0006] The utility model aims to solve the problem that the existing method for switching on and off the flue in the potassium chloride production process is time-consuming, labor-intensive and inefficient. Utility Model Content
[0007] In order to solve the above problems, the utility model provides a flue with an on-off control device, including a flue 1, a bracket 2, a blind plate 3 and a lifting device 4.

The blind plate 3 is arranged vertically, with the upper end located above the flue 1 and the lower end sliding through the switch port 11 and inserted into the flue 1. The lifting device 4 is fixedly arranged on the bracket 2, connected to the upper end of the blind plate 3, and is used to control the lifting and lowering of the blind plate 3.

The upper end of the blind plate 3 is connected to the lifting device 4, and the lower end is slid through the switch port 11 and inserted into the flue 1. The lifting device 4 controls the lifting of the blind plate 3. When the lifting device 4 drives the blind plate 3 to slide upward until the lower end of the blind plate 3 is close to the switch port 11, the flue 1 is opened. When the lifting device 4 drives the blind plate 3 to slide downward until the lower end of the blind plate 3 reaches the bottom of the flue 1, the flue 1 is cut off.
[0009] When switching between bag dust collector and cyclone dust collector for dust removal, the utility model does not need to remove fixing bolts, soft connections and other devices, and can quickly connect or disconnect the flue 1, and quickly switch between bag dust collector and cyclone dust collector for dust removal operation, which does not require the cooperation of maintenance personnel to prevent injuries to workers, and solves the problem that the existing method of switching the flue 1 on and off is time-consuming, labor-intensive and inefficient.

DETAILED DESCRIPTION
[0026] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0027] like Figure 1 and Figure 2 As shown, the flue with an on-off control device includes a flue 1, a bracket 2, a blind plate 3 and a lifting device 4. The flue 1 is arranged horizontally and extends in the front-to-back direction. The cross section of the flue 1 is square, and a switch port 11 for accommodating the blind plate 3 is provided on the top surface of the flue 1.
[0028] The switch port 11 is strip-shaped and extends in the left-right direction. The extension direction of the switch port 11 is perpendicular to the extension direction of the flue 1 , and both ends of the switch port 11 extend to the left and right sides of the flue 1 .
[0029] An elastic sealing gasket (not shown) is provided on the switch port 11. The elastic sealing gasket can improve the sealing performance of the switch port 11 and prevent dust leakage.
[0030] The bracket 2 is fixedly set on the flue 1 and is located above the switch port 11. The bracket 2 includes a fixing rod 21 and two support rods 22. The support rod 22 is vertically arranged, and the lower end is fixedly connected to the flue 1. The two support rods 22 are relatively arranged at the two ends of the switch port 11. The fixing rod 21 is horizontally arranged, and the left and right ends are respectively fixedly connected to the upper ends of the two support rods 22.
[0031] The blind plate 3 is vertically arranged, with the upper end located above the flue 1 and the lower end slidingly inserted into the flue 1 through the switch port 11 .
[0032] The width of the blind plate 3 is slightly smaller than the width of the cavity of the flue 1, so that the blind plate 3 can be inserted into the flue 1. The height of the blind plate 3 is slightly larger than the height of the flue 1, so that the lower end of the blind plate 3 abuts against the bottom surface of the flue 1 to cut off the flue 1. The upper end of the blind plate 3 is located above the switch port 11.
[0033] like Figure 1 and Figure 4 As shown, the lifting device 4 includes a fixed box 41, a lifting slide rail 42, a rotation power mechanism, a slider 44, a screw rod 45 and a connecting rod 46.
[0034] The fixing box 41 is square, with its lower end disposed on the flue 1 and its upper front end fixedly connected to the fixing rod 21 . A vertically extending lifting opening 411 is provided on the front side of the fixing box 41 .
[0035] The lifting rail 42 is vertically arranged on the inner wall of the fixed box 41. The rotating power mechanism is a rotating motor 43, which is fixedly arranged on the inner wall of the fixed box 41 and located at the upper end of the lifting rail 42. The slider 44 is slidably arranged on the lifting rail 42. The slider 44 is provided with a threaded hole matching the screw rod 45.
[0036] The upper end of the screw rod 45 is fixedly connected to the rotating shaft of the rotating motor 43, and the lower end extends vertically downward through the threaded hole on the slider 44. One end of the connecting rod 46 is fixedly connected to the slider 44, and the other end passes through the lifting port 411 and is fixedly connected to the blind plate 3.
[0037] When the lifting device 4 drives the blind plate 3 to slide upward until the lower end of the blind plate 3 is close to the switch port 11, the flue 1 is opened. When the lifting device 4 drives the blind plate 3 to slide downward until the lower end of the blind plate 3 reaches the bottom of the flue 1, the flue 1 is cut off.
[0038] like Figure 3 As shown, a guide rail 5 is provided on the flue 1, and the guide rail 5 includes a horizontal rail 52 and two vertical rails 51. The vertical rail 51 is vertically arranged, with the upper end located above the flue 1 and fixedly connected to the support rod 22, and the lower end extends through the flue 1 to the bottom of the flue 1 and is fixedly connected to the inner wall of the flue 1.

[0040] The horizontal rail 52 is fixedly arranged on the bottom surface of the flue 1 , and its two ends are fixedly connected to the lower ends of the two vertical rails 51 respectively. A fixing groove 521 for accommodating the blind plate 3 is provided on the horizontal rail 52 .
[0041] By providing vertical rails 51 on the left and right sides of the flue 1, the blind plate 3 can be guided and fixed, so that the blind plate 3 can only slide up and down along the guide grooves 511, preventing the blind plate 3 from tilting. This can also improve the sealing between the two sides of the blind plate 3 and the inner wall of the flue 1, preventing dust leakage. By providing horizontal rails 52 on the bottom surface of the flue 1, when the flue 1 needs to be cut off, the blind plate 3 is slid down to the bottom of the flue 1, so that the lower end of the blind plate 3 is inserted into the fixing grooves 521 on the horizontal rails 52. This can improve the sealing between the lower end of the blind plate 3 and the bottom surface of the flue 1, preventing dust leakage, and enhancing the stability of the blind plate 3.
[0042] Flue 1 conduction process: Rotate the motor 43 to control the screw rod 45 to rotate forward, and the screw rod 45 rotates to control the slider 44 to slide upward along the lifting slide rail 42, driving the blind plate 3 to slide upward until the lower end of the blind plate 3 is close to the top of the flue 1, so that the flue 1 is conducted (refer to Figure 5 ).
[0043] Flue 1 cutting process: When the motor 43 is turned to control the screw rod 45 to rotate in the opposite direction, the screw rod 45 rotates to control the slider 44 to slide downward along the lifting slide rail 42, driving the blind plate 3 to slide downward until the lower end of the blind plate 3 is inserted into the fixing groove 521 of the horizontal rail 52, cutting off the flue 1 (refer to Figure 6 ).
[0044] The utility model is provided with a switch port 11 on the top surface of the flue 1, and a lifting device 4 is provided above the flue 1 through a bracket 2. The upper end of the blind plate 3 is connected to the lifting device 4, and the lower end is slid through the switch port 11 and inserted into the flue 1. The lifting device 4 controls the lifting of the blind plate 3. When the lifting device 4 drives the blind plate 3 to slide upward until the lower end of the blind plate 3 is close to the switch port 11, the flue 1 is opened. When the lifting device 4 drives the blind plate 3 to slide downward until the lower end of the blind plate 3 reaches the bottom of the flue 1, the flue 1 is cut off.
[0045] When switching between bag dust collector and cyclone dust collector for dust removal, the utility model does not need to remove fixing bolts, soft connections and other devices, and can quickly connect or disconnect the flue 1, and quickly switch between bag dust collector and cyclone dust collector for dust removal operation, which does not require the cooperation of maintenance personnel to prevent injuries to workers, and solves the problem that the existing method of switching the flue 1 on and off is time-consuming, labor-intensive and inefficient.
[0046] It should be noted that the above-mentioned embodiments illustrate rather than limit the invention and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims.
