[0023] Example: See Figures 1 to 3 In an embodiment of the present invention, a smoke detection and suppression system for concrete production is provided, which is used to detect and suppress smoke in at least one batching bin 1, and is characterized in that it includes a dust suction pipe 2, a dust removal bin 3, a first air suction pump 4, and a second air suction pump 5, wherein the batching bin 1 is connected to the dust removal bin 3 by the dust suction pipe 2, and the dust removal bin 3 is provided with a first air suction pump 4 and a second air suction pump 5 that are symmetrically distributed on the left and right. The first air suction pump 4 and the second air suction pump 5 are alternately sucked, and the suction ends of the first air suction pump 4 and the second air suction pump 5 are provided with a filter screen. The first air suction pump 4 and the second air suction pump 5 can also pump air into the dust removal bin 3;

[0024] A stirring auger 9 is also rotatably provided in the dust removal bin 3 .

[0025] In addition, a first spray pipe 6 and a second spray pipe 7 are also embedded in the dust removal bin 3, wherein the spray direction of the first spray pipe 6 is away from the first air suction pump 4, and when the first air suction pump 4 pumps air into the dust removal bin 3, the first spray pipe 6 is opened, and the spray direction of the second spray pipe 7 is away from the second air suction pump 5, and when the second air suction pump 5 pumps air into the dust removal bin 3, the second spray pipe 7 is opened.

[0026] In the embodiment of the present invention, a stirring auger is provided in the dust removal bin, so that smoke dust can be collected and mixed directly in the dust removal bin to produce concrete. In this case, a first spray pipe and a second spray pipe can be directly provided to improve the dust removal effect by spraying.

[0027] Since the first air suction pump 4 and the second air suction pump 5 are alternately sucking, and the first air suction pump 4 and the second air suction pump 5 can also pump air into the dust removal bin 3, dust attached to the filter net can be removed by pumping air.

[0028] In addition, when the first air suction pump 4 pumps air into the dust removal bin 3, the second air suction pump 5 performs suction. At this time, the first spray pipe 6 is opened, and the mist sprayed therefrom can move toward the second air suction pump 5 to the greatest extent, thereby spraying most of the smoke and dust. Similarly, when the second air suction pump 5 pumps air into the dust removal bin 3, the first air suction pump 4 performs suction. At this time, the second spray pipe 7 is opened, and the mist sprayed therefrom can move toward the first air suction pump 4 to the greatest extent, thereby spraying most of the smoke and dust.

[0029] In this embodiment, a plurality of material supply tanks 8 are embedded in the upper portion of the dust removal bin 3 , and the material supply tanks can quantitatively supply a certain concrete raw material to the dust removal bin 3 .

[0030] In this embodiment, a smoke amount detection component is also provided on one side of the dust suction pipe 2. The smoke amount detection component can detect the amount of smoke sucked by the dust suction pipe 2 within a certain period of time. It also includes a controller, which can control the discharge amount of each supply tank 8 according to the amount of smoke.

[0031] In fact, each of the feed tanks 8 has the function of quantitative feeding, for example, the purpose of quantitative feeding is achieved by controlling the opening and closing time of the valve body, which will not be elaborated here.

[0032] In addition, different material supply tanks 8 may be pre-loaded with different materials, such as cement, sand, etc.

[0033] In this embodiment, Figure 3, the smoke dust amount detection component includes a detection bin 11, a weighing device 12, a temporary storage bin 13 and a telescopic rod 18, wherein the detection bin 11 is connected to one side of the dust suction pipe 2 through an inlet and outlet 16, a weighing device 12 is provided in the detection bin 11, a temporary storage bin 13 is slidably provided on the weighing device 12, a piston 14 is slidably provided in the temporary storage bin 13, and a connecting port is provided at one end of the temporary storage bin 13 away from the dust suction pipe 2, the telescopic end of the telescopic rod 18 can be inserted into the connecting port, and a limit ring 19 is also fixed to the telescopic end of the telescopic rod 18 so that the temporary storage bin 13 can be driven to move synchronously through the limit ring 19 when the telescopic rod 18 is extended, and a negative pressure hole is provided on the side of the telescopic end of the telescopic rod 18, and the telescopic end of the telescopic rod 18 has a flow channel, which is connected to the negative pressure hole, and the flow channel is also connected to the hose 20, and the hose 20 is connected to the external pump body so as to drive the temporary storage bin 13 to move synchronously when the telescopic rod 18 is retracted;

[0034] A limit plate 21 is fixed on the inner side of the detection bin 11 to provide a limit for the temporary storage bin 13;

[0035] The temporary storage bin 13 is provided with a through hole at a lower position on one side close to the inlet and outlet 16 .

[0036] In addition, the dust suction pipe 2 is also hinged with a second baffle 17 using a hinge shaft. The second baffle 17 corresponds to the position of the inlet and outlet 16, and the diameter of the second baffle 17 is larger than the diameter of the inlet and outlet 16. A second return torsion spring is also provided between the hinge shaft and the second baffle.

[0037] As a preferred embodiment, a first baffle 15 is rotatably connected to the through hole by a rotating shaft, and a first return torsion spring is further provided between the rotating shaft and the first baffle.

[0038] Therefore, during implementation, when the telescopic rod 18 is extended, the telescopic end of the telescopic rod 18 can be extended into the connecting port. At this time, under the action of the limit ring 19, the temporary storage bin 13 can move toward the inlet and outlet 16 as the telescopic rod 18 is extended, and pass through the inlet and outlet 16 into the dust suction pipe 2. Afterwards, the external pump body pumps air into the flow channel through the hose 20, and the gas flows out from the negative pressure hole and drives the piston 14 to move, thereby discharging the gas in the temporary storage bin 13 through the piston. Afterwards, the external pump body performs a suction action, thereby causing the piston 14 to reset and move. It collects the gas from the dust suction pipe 2, and when the telescopic rod 18 contracts, the temporary storage bin 13 can also be reset and moved under the action of negative pressure. Finally, the external pump body stops moving and the telescopic rod 18 continues to contract. At this time, the temporary storage bin 13 is separated from the telescopic rod 18 under the limit of the limit plate 21. At this time, the external pump body can also be used to pump air and use the negative pressure hole to blow off the dust on the surface of the weighing device 12 to ensure the accuracy of its weighing of the temporary storage bin 13. In addition, since the weight and volume of the temporary storage bin are known, the concentration of the gas inside it can be calculated.

[0039] In this embodiment, the controller can control the smoke amount detection component to measure the first smoke concentration g1 at the first time point, the second smoke concentration g2 at the second time point, the third smoke concentration g3 at the third time point, ..., the nth smoke concentration g at the nth time point. n , the n+1th smoke concentration g is measured at the n+1th time point n+1 ;

[0040] It also includes a flow meter provided on the dust suction pipe 2, for measuring the total gas flow m at the n+1th time point;

[0041] The amount of smoke is .

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
