Description
Technical Field
The utility model relates to a pitch apparatus for producing, especially a can effectively eliminate pitch agitating unit of smoke and dust, specific environment-friendly pitch agitating unit that says so.
Background
At present, when SMA asphalt concrete is produced, raw materials are mixed in a mixing pot. The wood fiber additive is added into a mixing pot in an air conveying mode, and is mixed with stone, mineral powder and asphalt at a high temperature. The mixing pot is closed, the top of the mixing pot is provided with a mineral aggregate scale, and the bottom of the mixing pot is provided with a discharge hole. The mineral aggregate scale is communicated with the pot body so as to add the raw materials into the pot after being weighed. Because the mineral aggregate scale is not tightly connected with the pan body, smoke, dust and the like in the pan body are easy to emerge from the place. Especially, when wood fiber is added by adopting an air blowing mode, positive pressure can be formed in the mixing pot, and a large amount of smoke and dust are easy to overflow to cause environmental pollution. Therefore, improvement is urgently needed so as to better solve the problem of smoke dust disposal during asphalt mixing and realize energy conservation and environmental protection.
SUMMERY OF THE UTILITY MODEL
The utility model aims at prior art not enough, provide an environment-friendly pitch mixing arrangement, can effectively collect wood fiber dust smoke and dust when pitch is stirred to with its input dust remover, realize cleaner production, satisfy the environmental protection requirement.
The technical scheme of the utility model is that:
an environment-friendly asphalt mixing device comprises a mixing pot, wherein a feeding hole and an induced draft hole are formed in the mixing pot; the feeding hole is connected with a wood fiber air feeder through a pipeline; the induced draft port passes through the induced draft fan and then is connected with a dust removal device; the feed inlet is positioned in the middle of the side wall of the mixing pot; the air inducing port is positioned at the top of the mixing pot.
Further, the device also comprises a feeding pipe and an induced draft pipe; the feed pipe and the induced draft pipe are both in a short pipe shape and are positioned inside the mixing pot; one end of the feeding pipe is connected with the feeding hole, and the other end of the feeding pipe is suspended obliquely downwards; one end of the induced draft pipe is connected with the induced draft port, and the other end of the induced draft pipe is suspended obliquely downwards.
Furthermore, the included angles between the feeding pipe and the air inducing pipe and the inner wall of the mixing pot are both 30-60 degrees.
Further, an air door is arranged on a pipeline between the induced draft opening and the induced draft fan; the air door is connected with the adjusting cylinder.
Further, the wood fiber air blower and the adjusting cylinder are respectively and electrically connected with the controller.
The utility model has the advantages that:
the utility model relates to a rationally, simple structure, convenient to use can be when pitch mixing production, effectively collects the dust smoke and dust that wood fibre produced to with in its input dust remover, realized cleaner production, and satisfied the environmental protection requirement.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1-a wood fiber blower; 2-feeding pipe; 3-a feed inlet; 4-mixing the pot; 5-induced duct; 6-induced draft; 7-adjusting the cylinder; 8-a damper; 9-a draught fan; 10-a dust removal device; 11-a controller.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1.
An environment-friendly asphalt mixing device comprises a mixing pot 4.
The middle part of the side wall of the mixing pot 4 is provided with a feeding hole 3. The feeding port 3 is connected with a wood fiber air feeder 1 through a pipeline, and wood fibers can be fed into the mixing pot 4 in an air feeding mode. And an air inducing port 6 is arranged at the top of the mixing pot 4. The induced draft 6 is connected with a dust removal device 10 after passing through an induced draft fan 9, and can suck out the smoke dust and the like in the mixing pot 4 and input the smoke dust and the like into the dust removal device 10 for collection.
The mixing pot 4 is also internally provided with a feeding pipe 2 and an induced draft pipe 5. The feed pipe 2 and the induced draft pipe 5 are both short tubular. One end of the feeding pipe 2 is connected with the feeding hole 3, and the other end of the feeding pipe is suspended obliquely downwards; one end of the induced draft pipe 5 is connected with the induced draft opening 6, and the other end is suspended obliquely downwards. Therefore, the gas in the mixing pot 4 can form spiral airflow, so that particles can sink conveniently, smoke and dust can be sucked away more easily, and the dust removal efficiency is improved. Preferably, the included angles between the feeding pipe 2 and the induced air pipe 5 and the inner wall of the mixing pot 4 are both 45 degrees. The length of the feeding pipe 2 is about 300mm, and the length of the induced air pipe 5 is about 200 mm.
Be equipped with air door 8 on the pipeline between induced air mouth 6 and the draught fan 9 to make this air door 8 link to each other with adjust cylinder 7, under this adjust cylinder 7's of accessible effect, it is right the aperture of air door 8 is adjusted, fully satisfies the demand of induced air dust absorption.
Further, the wood fiber blower 1 and the adjusting cylinder 7 are respectively and electrically connected with a controller 11. The controller 11 is a PLC, and can coordinate the action time, the action size and the like of the wood fiber air feeder 1 and the adjusting cylinder 7 by programming corresponding programs, so that the feeding and the induced air are adaptive, and the normal production and the high-efficiency dust removal are ensured.
The dust removal device 10 can select conventional cloth bag dust removal products, is convenient to purchase and reduces the cost.
The utility model discloses can send wood fiber into the mix pot through the wood fiber forced draught blower when pitch mixing production, simultaneously, through opening draught fan and air door, with suction mix pot such as dust smoke and dust that wood fiber produced to input and collect in the dust collector, avoided overflowing from the mix pot and cause the pollution to the environment such as smoke and dust, thereby, realized cleaner production, and satisfied the environmental protection requirement.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
