Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1 and 2, the device for detecting coal blockage of a coal chute of a pressure sensor is installed outside the coal chute and has a cavity box structure with an open bottom surface and an open side surface, and comprises: device wall 1, device floor 2, pressure sensor 3, flap 4 and alarm device 5, wherein,
the device bottom plate 2 is arranged at the bottom opening of the device wall 1 and covers the bottom opening, and the left side of the device bottom plate 2 is connected with the lower end of the left side surface of the device wall 1;
the pressure sensor 3 is connected with the device bottom plate 2, and the pressure sensor 3 is positioned in the cavity of the detection device;
the right end of the top of the device wall 1 is connected with a coal dropping cylinder wall 8 through a fixing part 7;
specifically, the fixing part is a 7-position L-shaped metal baffle plate;
the side opening of the device wall 1 corresponds to the opening of the coal dropping cylinder wall 8; the right side of the device bottom plate 2 is connected with the coal breakage cylinder wall 8 through a second rotating shaft 9, and the device bottom plate 2 inclines downwards to the right and forms an acute included angle with the coal breakage cylinder wall 8; specifically, the included angle between the bottom plate 2 of the device and the coal dropping cylinder wall 8 is 50 degrees or 60 degrees;
the movable baffle 4 is arranged at the side opening of the detection device and covers the side opening, and is connected with the top of the device wall 1 through a first rotating shaft 6;
the alarm device 5 is connected to the outer side of the device wall 1 and is in communication connection with the sensor 3.
Example 1
When no coal falls into the detection device, the pressure value of the pressure sensor 3 is 0.
When the coal chute is blocked, the movable baffle 4 is turned over along the first rotating shaft 6 by the extrusion acting force of the blocked coal, and the coal enters the cavity of the detection device and generates pressure on the induction baffle 12. Specifically, the induction baffle 12 is made of alloy or steel. The sensing baffle 12 rotates around the third rotating shaft 11 along the arc-shaped baffle 10 under the action of pressure, meanwhile, the elastic part 13 and the pressure sensor 3 are extruded, the pressure applied on the pressure sensor 3 is gradually increased, after the pressure exceeds a set pressure threshold value and the duration reaches a set time threshold value, the alarming device 5 and the alarming and flashing lamp are triggered, the alarming lasts for 2 minutes and gives an alarm every 1 minute.
After the staff receives the alarm, the alarm device can be manually closed and the blockage in the coal dropping cylinder can be cleaned.
After the blockage in the coal dropping cylinder is removed, the buckling device 14 is pulled manually to enable one end of the buckling device to be separated from the clamping groove 15 and rotate along the fourth rotating shaft 15, at the moment, the device bottom plate 2 is released from fixation and can rotate downwards along the second rotating shaft 9, and the coal in the detection device can drop. After the coal in the detection device is removed, the sensing baffle 12 is restored to the initial state under the elastic force of the elastic component 13, and the pressure value of the sensor 3 is restored to 0.
The staff can clean detection device cavity. After the detection device is cleaned, a worker can fix one end of the fastening device 14 in the clamping groove 15 again, and the switch of the alarm device 5 is turned on, so that the device enters a coal blockage detection state again.
Because the sensor 3 is positioned in a cavity formed by the device bottom plate 2, the arc-shaped baffle plate 10 and the induction baffle plate 12, the direct impact damage and pollution of coal to the sensor 3 can be reduced, and the service life of the sensor 3 is prolonged.
Example 2
When coal in the coal dropping cylinder normally passes through, the movable baffle 4 is impacted by the interaction force, and when the impact force is small, the movable baffle 4 cannot be overturned around the first rotating shaft 6; when the impact acting force is large, the movable baffle 4 turns around the first rotating shaft 6, and coal enters the cavity of the detection device and falls on the device bottom plate 2. Because the device bottom plate 2 is an inclined bottom plate, coal finally falls in an included angle between the device bottom plate 2 and the coal dropping cylinder wall 8, and the sensing baffle plate 12 and the pressure sensor 3 are not subjected to pressure from the coal, so that the alarm device 5 cannot be triggered.
Coal in the coal breakage section of thick bamboo is when normally passing through because interaction force striking adjustable fender 4, when striking effort is great, adjustable fender 4 is around the upset of first pivot 6, coal gets into the detection device cavity and falls on response baffle 2, set up elastomeric element 13 because of responding to between baffle 12 and the device pad 2, elastomeric element 13's cushioning effect makes response baffle 12 not touch pressure sensor 3, simultaneously because of response baffle 12 is located the device bottom plate 2 of slope, coal finally falls in the contained angle of device bottom plate 2 and coal breakage section of thick bamboo wall 8, pressure sensor 3 does not receive the pressure that comes from coal, then can not trigger alarm device 5.
When coal in the coal dropping cylinder normally passes through, the movable baffle 4 is impacted by an interaction force, when the impact force is larger, the movable baffle 4 turns around the first rotating shaft 6, the coal enters the cavity of the detection device and falls on the sensing baffle 2, the sensing baffle 12 receives the pressure of the coal and extrudes the elastic component 13 and the pressure sensor 3, and the pressure value received by the pressure sensor 3 does not reach a set pressure threshold value, so that the alarm device cannot be triggered; or the coal that falls into is to the extrusion effect of response baffle 12 for the pressure that pressure sensor 3 received reaches the pressure threshold value of settlement, nevertheless because of the coal falls on response baffle 12 back gliding and falls into the device bottom plate 2 and falls into the contained angle of coal breakage section of thick bamboo wall 8, the pressure that pressure sensor 3 received does not reach the time threshold value of settlement, then can not trigger alarm device 5.
And the alarm triggering pressure threshold and the time threshold of the pressure sensor 3 are set, so that the blockage false alarm rate can be reduced.
It should be noted that the directions and positions indicated as "upper", "lower", "left", "right", "inner", "outer", "middle", etc. used in the present invention are only for convenience of description and simplification of description based on the directions or positional relationships shown in the drawings, and do not indicate or imply that the indicated device or element must have a specific direction or be constructed and operated in a specific positional relationship, and thus, should not be construed as limiting the present invention.
