Description

Technical Field

[0001] This invention relates to the field of fertilizer production technology, and in particular to a dust removal device for fertilizer workshops. Background Technology

[0002] Chemical fertilizers, or simply fertilizers, are fertilizers containing one or more nutrients needed for crop growth, produced by chemical or physical methods. They are also called inorganic fertilizers, including nitrogen fertilizers, phosphate fertilizers, and compound fertilizers. Generally, during fertilizer production, they are made into granules or balls, and then dried, screened, and transported before packaging. Existing fertilizer conveyor belts are all open conveyor belts, which generate large dust particles during transportation, not only polluting the production environment but also causing harm to human health.

[0003] A dust removal device for a fertilizer production line is disclosed in application number CN202020789561.5. This device includes a dust collection hood, a collection hopper, a fixed box, and a dust collection box. The dust collection hood is fixedly installed on the upper part of the conveyor frame and connected to the collection hopper via a conduit. An air guide box connected to a first axial flow fan is installed on the upper part of the collection hopper. The lower part of the collection hopper is connected to the fixed box, and the dust collection box is installed inside the fixed box. A second partition plate is installed inside the dust collection box, dividing it into chamber A and chamber B. A spray pipe and a receiving box are installed in chamber A, as are a second axial flow fan and a dust collection bag. The collection hopper is a rectangular cavity structure with an open bottom. The bottom of the collection hopper is connected to the conveyor frame via a support mechanism, which includes a screw, a fixed rod, and a torsion nut. Although the device can absorb dust generated on the production line, when the production line is too long, the fixed position of the dust hood means that it cannot collect all the dust generated on the production line.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0017] like Figure 1 As shown, the present invention provides a dust removal device for a fertilizer workshop, including a conveyor frame 1, on which a retractable dust collection component 2 is slidably connected. The retractable dust collection component 2 includes a set of dust collection hoods 2.1, and a set of four traveling wheels 2.2 are connected to the lower side of each dust collection hood 2.1. Each traveling wheel 2.2 is an existing brake wheel with a built-in braking mechanism. When it travels to a fixed position, the brake is pressed to fix it.

[0018] Two slid grooves 1.1 are provided on the conveyor frame 1. The corresponding walking wheels 2.2 are slidably connected in the slid grooves 1.1. The slid grooves 1.1 ensure that the walking wheels 2.2 can only travel in a straight line and prevent the walking wheels 2.2 from falling off the slid grooves 1.1.

[0019] like Figure 2 As shown, a set of placement tubes 2.4 are connected to both sides inside each dust hood 2.1. One end of the placement tube 2.4 is connected to the corresponding dust hood 2.1, and the other end of the placement tube 2.4 is connected to the outside of the dust hood 2.1. A telescopic tube 2.3 is connected inside the placement tube 2.4. In this embodiment, the telescopic tube 2.3 is a corrugated tube. When the corrugated tube is contracted, it can be stored inside the placement tube 2.4. When the distance between two dust hoods 2.1 increases, the corrugated tube becomes longer and can also connect the two adjacent dust hoods 2.1.

[0020] like Figure 3 As shown, a first snap-fit ​​component 2.5 and a second snap-fit ​​block 2.6 are connected to each dust cover 2.1, and the first snap-fit ​​component 2.5 engages with the corresponding second snap-fit ​​block 2.6.

[0021] The first locking component 2.5 includes a rotating rod 2.51 and an elastic support 2.7. The rotating rod 2.51 is rotatably connected to the corresponding dust cover 2.1, that is, a rotating shaft is connected to the dust cover 2.1. The rotating rod 2.51 has a rotating hole, and the rotating shaft is inserted into the rotating hole so that the rotating rod 2.51 can rotate around the rotating shaft. A first locking block 2.52 is connected to one end of the rotating rod 2.51. The first locking block 2.52 engages with the corresponding second locking block 2.6. Both the first locking block 2.52 and the second locking block 2.6 are right-angled trapezoidal structures, so that the inclined surfaces of the two corresponding first locking blocks 2.52 and second locking blocks 2.6 are arranged opposite each other.

[0022] The elastic support 2.7 includes a sleeve 2.71 connected to the dust cover 2.1. A support rod 2.72 is inserted into the sleeve 2.71. An elastic element, which is a spring, is connected between the bottom of the support rod 2.72 and the sleeve 2.71. The spring supports the support rod 2.72, so that the support rod 2.72 is supported below one side of the rotating rod 2.51, preventing the rotating rod 2.51 from rotating downward. By pressing the rotating rod 2.51 downward by hand, the support rod 2.72 is retracted into the sleeve 2.71. After the first locking block 2.52 disengages from the second locking block 2.6, the two dust covers 2.1 can be separated.

[0023] like Figure 4 As shown, an exhaust device 3 is provided on one side of the conveyor frame 1. The exhaust device 3 includes a recycling box 3.1. Inside the recycling box 3.1, from top to bottom, there are filter elements 3.2, filter screens 3.3, and an exhaust fan 3.4. In this embodiment, the filter element 3.2 is an annular filter screen. The recycling pipe 4 is connected to the upper side of the recycling box 11. The recycling pipe 4 is connected to one of the dust suction hoods 2.1. When dust enters the recycling box 3.1, it will first enter the annular filter screen and then be filtered by the filter screen 3.3. The filter screen 3.3 is set at an angle. When there is an opening on one side of the recycling box 3.1, a door is hinged at the opening. The lower side of the filter screen 3.3 is close to the door, so that the dust slides down the slope of the filter screen 3.3, which is convenient for employees to handle the dust later.

[0024] This device can move a set of dust collection hoods to different positions on the conveyor frame 1 for dust collection, and can also allocate the number of dust collection hoods according to the amount of dust generated at each workstation, thereby enabling better dust removal in the fertilizer workshop.
