Description

Technical Field

[0001] The utility model relates to the technical field of hot-melt coating processing, in particular to a dust removal mechanism for hot-melt coating processing. Background Art

[0002] Thermoplastic road marking paint is a kind of paint applied on the road to mark road lines. Thermoplastic reflective road marking paint is mainly used on highways and expressways above level 2. The thickness of the marking coating drawn by this paint is 1.0-2.5mm. Reflective glass beads are mixed in the paint, and reflective glass beads are sprinkled on the construction surface during the marking construction. During the production process of hot-melt paint, a large amount of dust will be generated. In order to avoid environmental pollution caused by this dust, dust removal devices will be installed during the production of hot-melt paint;

[0003] The prior art CN202020633690.5 is a dust removal device for hot melt coating production. Through the setting of the skeleton device, when the dust collector bag is mounted on the outer surface of the first ring from bottom to top, the pushing force will make the inner side of the push plate fit with the outer surface of the first ring, and the outer side of the push plate is in contact with the dust collector bag. After the dust collector bag is installed, the rebound force of the spring will push the push plate to prop up the bag mouth of the dust collector bag, thereby ensuring the firmness of the dust collector bag and preventing the dust collector bag from falling off from the skeleton device, thereby improving the dust removal effect. Moreover, through the coordinated use of the air pipe and the connecting pipe, when the external dust collector air bag is working, the connecting pipe and the venturi tube will perform pulse blowing on the interior of the skeleton device, thereby shaking off the dust adsorbed by the dust collector bag to the inside of the ash hopper, thereby improving the use effect of the dust collector bag.

[0004] However, the dust removal device used in the production of hot melt coatings will drive some dust out of the device through the exhaust pipe when exhausting gas, thereby affecting the environment; therefore, it does not meet the existing needs. In this regard, we propose a dust removal mechanism for hot melt coating processing. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a dust removal mechanism for hot-melt coating processing. In order to solve the above technical problems, the technical solution of the utility model is: a dust removal mechanism for hot-melt coating processing, including a processing box, an air inlet pipe is provided on one side of the processing box, a discharge pipe is provided at the bottom end of the processing box, and an exhaust pipe is fixedly connected to the upper end of the processing box away from the air inlet pipe, a slot is provided on one side of the upper end of the exhaust pipe, a top plate is provided at the upper end of the slot, side plates extending through the slot are fixedly connected on both sides of the bottom end of the top plate, a filter screen is fixedly connected between the side plates on both sides, grooves are provided at the upper ends of the side plates on both sides away from each other, and blocks are movably connected to the insides of the grooves on both sides.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model inserts the side panels at both sides of the bottom end of the top plate into the interior of the slot. When the side panels enter the interior of the slot, the inner wall of the slot contacts the outer wall of the card block, thereby pushing the card block to move toward the inside of the groove and slide along the outer surface of the fixing rod, thereby compressing the spring to produce deformation. When the position of the card block corresponds to the position of the limiting groove, the compression of the spring is released, thereby pushing the card block to move toward the inside of the limiting groove to limit the position of the side panel. At this time, the filter screen arranged between the two side panels can block the dust inside the isolation processing box from being discharged through the exhaust pipe, and the dust collecting frame can be arranged to collect the accumulated dust, and the sealing strip can be arranged to prevent the dust from leaking from the gap between the side panel and the slot.

[0013] 2. The utility model pulls the top plate upwards, and the inclined surfaces of the blocks on the side plates on both sides slide in contact with the upper edges of the limit grooves, and the rounded corners on the upper ends of the blocks are set to push the extrusion blocks toward the inside of the grooves, so that the side plates drive the filter screen to detach from the inside of the slots, thereby facilitating the cleaning of the filter screen in and out and preventing excessive dust accumulation from clogging the exhaust pipe.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1 As shown, the utility model describes a dust removal mechanism for hot-melt coating processing, comprising a processing box 1, an air inlet pipe 2 is provided on one side of the processing box 1, a discharge pipe 4 is provided at the bottom end of the processing box 1, and an upper end of the processing box 1 away from the air inlet pipe 2 is fixedly connected with an exhaust pipe 3, a slot 301 is provided on one side of the upper end of the exhaust pipe 3, a top plate 5 is provided at the upper end of the slot 301, side plates 6 that extend through and extend into the slot 301 are fixedly connected to both sides of the bottom end of the top plate 5, a filter screen 7 is fixedly connected between the side plates 6 on both sides, grooves 601 are provided at the upper ends of the side plates 6 on both sides away from each other, and blocks 9 are movably connected inside the grooves 601 on both sides.

[0021] As the preferred technical solution of this embodiment, Figure 2 and Figure 4 As shown, the interior of the grooves 601 on both sides are fixedly connected with a fixing rod 8, and the clamping block 9 is movably connected to the end of the fixing rod 8 away from the inner wall of the groove 601. A connecting groove 901 is provided on the side of the clamping block 9 close to the fixing rod 8, and one end of the fixing rod 8 is movably extended through the interior of the connecting groove 901, and one end of the fixing rod 8 is extended through the interior of the connecting groove 901 and is fixedly connected to a limiting plate 11, a spring 10 is fixedly connected between one side of the clamping block 9 and one side of the inner wall of the groove 601, and the spring 10 is wound around the outer surface of the fixing rod 8, and limiting grooves 302 are provided on both sides of the inner wall of the slot 301 close to the upper end, and the clamping blocks 9 on both sides are respectively clamped in the corresponding limiting grooves 302.

[0022] In this embodiment, by inserting the side panels 6 on both sides of the bottom end of the top plate 5 into the interior of the slot 301, when entering the interior of the slot 301 through the side panels 6, the inner wall of the slot 301 contacts the outer wall of the block 9, thereby pushing the block 9 to move toward the inside of the groove 601 and slide along the outer surface of the fixing rod 8, thereby compressing the spring 10 to produce deformation. When the position of the block 9 corresponds to the position of the limiting groove 302, the compression of the spring 10 is released, thereby pushing the block 9 to move toward the inside of the limiting groove 302 and limiting the position of the side panels 6. At this time, the filter screen 7 set between the two side panels 6 can prevent the dust inside the processing box 1 from being discharged through the exhaust pipe 3.

[0023] As the preferred technical solution of this embodiment, Figure 3 As shown, a dust collecting frame 12 is fixedly connected between the bottom ends of the side panels 6 on both sides, and a sealing strip 13 is fixedly connected to the sides of the two side panels 6 that are away from each other, and the sealing strip 13 is in close contact with the inner wall of the slot 301. The dust collecting frame 12 can be set to collect the accumulated and fallen dust, and the sealing strip 13 can be set to prevent dust from leaking out from the gap between the side panel 6 and the slot 301.

[0024] As the preferred technical solution of this embodiment, Figure 4 As shown, the upper ends of the two blocks 9 that are away from each other are both inclined, and the upper end faces of the blocks 9 are chamfered. By pulling the top plate 5 upward, the inclined surfaces of the blocks 9 on the side plates 6 on both sides slide in contact with the upper edges of the limiting grooves 302, and through the chamfered corners of the upper ends of the blocks 9, the blocks 9 are pushed and squeezed to move toward the inside of the groove 601, so that the side plates 6 drive the filter screen 7 to disengage from the inside of the slot 301, thereby facilitating the cleaning of the filter screen 7 in and out, and preventing excessive dust accumulation from clogging the exhaust pipe 3.

[0025] Working principle: by inserting the side plates 6 on both sides of the bottom end of the top plate 5 into the interior of the slot 301, when entering the interior of the slot 301 through the side plates 6, the inner wall of the slot 301 contacts the outer wall of the card block 9, thereby pushing the card block 9 to move toward the inside of the groove 601 and slide along the outer surface of the fixing rod 8, thereby squeezing the spring 10 to compress and deform. When the position of the card block 9 corresponds to the position of the limiting groove 302, the squeezing of the spring 10 is released, thereby pushing the card block 9 to move toward the inside of the limiting groove 302, limiting the position of the side plates 6. At this time, the filter screen 7 set between the two side plates 6 can block and isolate the processing box 1. The dust is discharged through the exhaust pipe 3, and the dust collecting frame 12 can collect the accumulated and fallen dust, and the sealing strip 13 can prevent the dust from leaking out from the gap between the side panel 6 and the slot 301; by pulling the top panel 5 upward, the inclined surfaces of the blocks 9 on the side panels 6 on both sides slide in contact with the upper edges of the limiting grooves 302, and the rounded corners of the upper ends of the blocks 9 are set to push the squeeze blocks 9 toward the inside of the groove 601, so that the side panels 6 drive the filter screen 7 to disengage from the inside of the slot 301, thereby facilitating the cleaning of the filter screen 7 in and out and preventing excessive dust accumulation from clogging the exhaust pipe 3.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
