Description
Technical Field
The utility model belongs to the technical field of the sack cleaner unloads the sediment equipment, concretely relates to novel lock wind spiral unloads sediment device for dust remover.
Background
In the prior art, a bag-type dust collector is the most widely used dust collector for up-to-standard emission of particulate matters, and the working principle of the bag-type dust collector is that dust-containing gas is filtered and settled to an ash hopper at the bottom of the dust collector, and settled dust is conveyed out through a spiral conveying pipe.
Because the interior of the bag-type dust collector is in a negative pressure environment, a rotary air-locking blanking valve needs to be additionally arranged at the outlet of the spiral feeding pipe, so that the blanking can be ensured, and external wind power cannot enter the bag-type dust collector. However, the rotary air-locking blanking valve needs to use an additional motor to drive the circular spaced air-locking disc to rotate, and the air-locking disc rotates in a low-speed intermittent manner, so that the cost of the corresponding motor is high, and the overall structure is complex.
Disclosure of Invention
The utility model aims at solving the technical problems of complex structure and high cost in the prior art, and providing a novel air-locking spiral slag discharging device for a dust remover so as to overcome the defects of the prior art.
The utility model discloses a realize through following technical scheme:
the utility model relates to a novel air-locking spiral slag discharging device for a dust remover, which comprises an ash bucket fixedly communicated with the bottom of a bag-type dust remover; the key points are as follows:
a material level height sensor is arranged at the bottom of the ash hopper;
the bottom end of the ash bucket is provided with a horizontally arranged feeding pipe; the top of the feeding pipe is communicated with the bottom of the ash hopper;
a transmission motor is arranged at one end of the feeding pipe, and a rotating shaft of the transmission motor is in transmission connection with a spiral feeding rod arranged in the feeding pipe;
the other end of the feeding pipe is provided with an extension part with the length extended beyond the diameter of the ash hopper, and the bottom end of the extension part is provided with a discharge opening;
the material level height sensor and the transmission motor are respectively electrically connected with the controller.
The utility model discloses rational in infrastructure, the length of conveying pipe has carried out the extension, and extension protrusion in the diameter of ash bucket, and then with the position deviation of discharge opening in the bottom of ash bucket, can utilize the lime-ash in the conveying pipe to carry out the shutoff, has saved the cost of installing of gyration lock wind discharge valve, and the structure is simplified greatly. The ash and slag height in the ash bucket can be monitored by the material level height sensor, and when the height reaches a set value, the transmission motor is automatically started to rotate through the controller, so that the spiral feeding rod is driven to rotate, and ash and slag are discharged. The rotary drum is automatically stopped after being discharged for a certain time, and the air locking effect of preventing wind from reversely flowing into the bag-type dust collector can be realized by plugging the residual ash in the feeding pipe.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of a slag discharging device in the prior art.
In the figure, the device comprises an ash hopper 1, an ash hopper 2, a transmission motor 3, a feeding pipe 4, a material level height sensor 5, a spiral feeding rod 6, a discharge opening 7 and an extension part.
Detailed Description
Referring to fig. 1 and 2, the utility model relates to a novel air-locking spiral slag discharging device for a dust remover, which comprises an ash bucket 1 fixedly communicated with the bottom of a bag-type dust remover;
a material level height sensor 4 is arranged at the bottom of the ash hopper 1;
the bottom end of the ash bucket 1 is provided with a horizontally arranged feeding pipe 3; the top of the feeding pipe 3 is communicated with the bottom of the ash hopper 1;
a transmission motor 2 is arranged at one end of the feeding pipe 3, and a rotating shaft of the transmission motor 2 is in transmission connection with a spiral feeding rod 5 arranged in the feeding pipe 3;
the other end of the feeding pipe 3 is provided with an extension part 7 with the length extended beyond the diameter of the ash hopper 1, and the bottom end of the extension part 7 is provided with a discharge opening 6;
the material level height sensor 4 and the transmission motor 2 are respectively electrically connected with a controller.
The utility model discloses rational in infrastructure, the length of conveying pipe has carried out the extension, and extension protrusion in the diameter of ash bucket, and then with the position deviation of discharge opening in the bottom of ash bucket, can utilize the lime-ash in the conveying pipe to carry out the shutoff, has saved the cost of installing of gyration lock wind discharge valve, and the structure is simplified greatly. The ash and slag height in the ash bucket can be monitored by the material level height sensor, and when the height reaches a set value, the transmission motor is automatically started to rotate through the controller, so that the spiral feeding rod is driven to rotate, and ash and slag are discharged. The rotary drum is automatically stopped after being discharged for a certain time, and the air locking effect of preventing wind from reversely flowing into the bag-type dust collector can be realized by plugging the residual ash in the feeding pipe.
Traditional pay-off pipe length is unanimous with the external diameter of ash bucket, does not add and establishes gyration lock wind unloading valve and will cause ash sediment discharge back ash bucket to link up with the external world, causes the sack cleaner internal pressure to change, consequently must set up the lock wind device and carry out the separation, and overall structure is complicated and with high costs. The utility model discloses utilize lime-ash self to carry out the shutoff after the length of extension conveying pipe, can realize locking the inclosed effect of wind completely, compare the structure with the conventional art and obtain obvious simplification, cost reduction is very showing, and the effect is obvious.
The utility model provides an its length of extension is greater than about 1 meter of ash bucket diameter, and helical blade closely cooperates with the conveying pipe inner wall in this 1 meter spiral interval, and the clearance dwindles as far as possible, when the lime-ash dashes full bottom conveying pipe, its effect that just can reach the lock wind itself. In addition, the transmission motor runs intermittently, the operation is carried out when a certain amount of ash is accumulated, and the spiral stops running after the materials are emptied.
The utility model relates to a rationally, novel structure, the good reliability, and maintain convenient simple. Compared with the traditional combination of a spiral air locking valve, the air locking valve saves cost, saves space, is easy to overhaul and saves energy consumption.
