Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, and in particular to a dust and flue gas concentration detection device. Background Technology

[0002] Flue gas is a mixture of gases and soot, and is a major cause of atmospheric pollution in residential areas. The composition of flue gas is very complex, including suspended particles, sulfides, carbon dioxide, nitrogen, oxygen, and hydrocarbons. Therefore, flue gas is quite harmful to the environment, so it generally needs to be treated and tested to meet standards before it can be released.

[0003] For example, Chinese utility model patent application number CN202122910101.0 discloses a dust and flue gas concentration detection device, including: a housing, a dust and flue gas tester, an inverted conical barrel, and connecting pipes. The dust and flue gas tester is installed inside the housing, and the inverted conical barrel is installed on the top of the housing. A six-hole connector is provided on the top of the dust and flue gas tester. The inverted conical barrel connects the outside world to the six-hole connector. An exhaust fan is installed inside the six-hole connector. Connecting pipes are also provided on both sides of the six-hole connector. Installation pipes connecting the outside world to the inside of the housing are respectively provided on both sides of the housing. One end of each of the two connecting pipes is connected to the two installation pipes respectively. A first protective net is detachably installed inside the inverted conical barrel through an installation component. A second protective net is installed inside each installation pipe through an installation component. Locking components for locking the second protective net inside the corresponding installation pipe are provided on both sides of the housing. This solves the problem that the protective nets of existing dust and flue gas detection devices are not easy to remove in the prior art.

[0004] Although the device can disassemble the protective net, when disassembling the first protective net, the worker needs to pull the two ropes with both hands at the same time. Therefore, when disassembling the first protective net, another person is needed to assist in removing it, making the operation process quite cumbersome. Furthermore, when cleaning the protective net, each one needs to be manually replaced before the device can be used again, which reduces the detection efficiency of smoke and dust. Utility Model Content

[0005] This utility model discloses a dust and flue gas concentration detection device, which solves the problem that it requires two people to remove the first protective net, the operation process is relatively cumbersome, and when cleaning the protective net, it is necessary to manually replace each one, which reduces the efficiency of dust and flue gas detection.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A dust and flue gas concentration detection device includes a housing, inside which a dust and flue gas tester is installed. An inverted conical barrel extends through the top of the housing. A six-hole connector is located on the top of the dust and flue gas tester. The bottom of the inverted conical barrel is connected to the six-hole connector. An exhaust fan is installed inside the six-hole connector. Connecting pipes are connected to both sides of the six-hole connector. Two through holes are provided on both sides of the housing, each connecting to one of the connecting pipes. A placement plate is located on the top of the inverted conical barrel. Two symmetrically arranged grooves are formed on the top of the placement plate. Inside, there is a first protective net, and the bottom of the placement plate has a round hole corresponding to the first protective net; both sides of the box are equipped with movable plates that block the perforations, and the opposite sides of the two movable plates are equipped with two symmetrical placement slots, in which a second protective net is placed. The inner wall of the placement slot is fixed with a baffle that blocks the side of the second protective net away from the box, and the movable plates have holes corresponding to the second protective net; the box is equipped with an electric telescopic rod for driving the first protective net and the two second protective nets to move synchronously.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] First, align one of the No. 1 protective nets on the placement plate with the top of the inverted conical barrel, and align one of the No. 2 protective nets on the moving plate with the perforation. When the smoke and gas outside the chamber passes through the No. 1 protective net, it can enter the inverted conical barrel through the corresponding hole. When the smoke and gas outside the chamber passes through the No. 2 protective net, it can enter the connecting pipe through the perforation. The baffle can confine the No. 2 protective net within the placement slot. When it is necessary to replace the No. 1 and No. 2 protective nets that have been in use for a long time, activate the electric telescopic rod to align the placement plate and the two moving plates... After the moving plate moves synchronously, another clean No. 1 protective net on the placement plate aligns with the inverted conical barrel, and at the same time, another clean No. 2 protective net on the moving plate aligns with the perforation. Then, the worker can remove the used No. 1 protective net from the groove on the placement plate and the used No. 2 protective net from the placement slot on the moving plate. This utility model allows for simple and quick disassembly of the No. 1 and No. 2 protective nets without stopping the machine to disassemble or replace them, thus avoiding a reduction in the detection efficiency of smoke and dust gases.

[0015] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a dust and flue gas concentration detection device, including a housing 1, a dust and flue gas tester 2 installed inside the housing 1, an inverted conical barrel 3 penetrating through the top of the housing 1, a six-hole connector 4 installed on the top of the dust and flue gas tester 2, the bottom of the inverted conical barrel 3 connected to the six-hole connector 4, an exhaust fan installed inside the six-hole connector 4, and connecting pipes 5 connected to both sides of the six-hole connector 4. Through holes 11 are opened on both sides of the housing 1, and the two through holes 11 are respectively connected to the two connecting pipes 5. A placement plate 6 is provided on the top of the inverted conical barrel 3, and two symmetrically arranged grooves are opened on the top of the placement plate 6. The box 1 contains a first protective net 61, and the bottom of the placement plate 6 has a round hole corresponding to the first protective net 61. Both sides of the box 1 are provided with movable plates 7 that block the through holes 11. The opposite sides of the two movable plates 7 are provided with two symmetrical placement slots 71. The second protective net 72 is placed in the placement slots 71. The inner wall of the placement slots 71 is fixed with a baffle 75 that blocks the side of the second protective net 72 away from the box 1. The movable plates 7 have holes corresponding to the second protective net 72. The box 1 is provided with an electric telescopic rod 8 for driving the first protective net 61 and the two second protective nets 72 to move synchronously. A first protective net 61 can be placed in a groove on the placement plate 6, and a second protective net 72 can be placed in a placement slot 71 on the moving plate 7. The groove prevents the first protective net 61 from falling off the placement plate 6. At least two baffles 75 are placed in the placement slot 71, symmetrically distributed front and back, so that when the second protective net 72 is placed in the placement slot 71, the baffles 75 can block it, preventing it from falling out. The first protective net 61 corresponds to the inverted conical barrel 3, and the second protective net 72 corresponds to the perforation 11. The model of the smoke and dust tester 2 is CCZ1000. During use, the exhaust fan in the six-hole connector 4 draws smoke and dust from outside the housing 1 into the six-hole connector 4 through the two perforations 11 and the inverted conical barrel 3, respectively. The mixed flue gas is then transported to the flue gas tester 2, which transmits the detected information to the display screen on the outer wall of the housing 1. When the No. 1 protective net 61 and the No. 2 protective net 72 need to be removed and replaced after long-term use, the clean No. 1 protective net 61 can be placed in another groove on the placement plate 6, and the clean No. 2 protective net 72 can be placed in another placement slot 71 on the moving plate 7. After the electric telescopic rod 8 is activated to drive the placement plate 6 and the two moving plates 7 to move, the clean No. 1 protective net 61 is aligned with the inverted conical barrel 3, and the clean No. 2 protective net 72 is aligned with the perforation 11, so that the flue gas can continue to enter the flue gas tester 2 for inspection. At this time, the staff can then remove the No. 1 protective net 61 and the No. 2 protective net 72 after use.

[0017] like Figure 1As shown, the telescopic end of the electric telescopic rod 8 is fixed with a connecting plate 81, and the placement plate 6 and the two movable plates 7 are respectively fixed with fixed rods 82 connected to the connecting plate 81. After the electric telescopic rod 8 is started, the telescopic end of the electric telescopic rod 8 can drive the fixed rods 82 to move through the connecting plate 81, so that the placement plate 6 and the two movable plates 7 can move forward or backward, thereby changing the position of the placement plate 6 and the two movable plates 7.

[0018] like Figure 1 As shown, a support plate 9 connected to the fixed end of the electric telescopic rod 8 is fixed on the housing 1, and a storage battery 91 is fixed on the support plate 9. The storage battery 91 can supply power to the electric telescopic rod 8, and the support plate 9 can increase the stability of the electric telescopic rod 8 fixed on the housing 1.

[0019] like Figure 1 As shown, the bottom of the placement plate 6 is fixed with a vertical plate 64 that is slidably connected to the top of the box body 1; both sides of the box body 1 are fixed with bearing bars 76, and the bottoms of the two movable plates 7 are slidably connected to the tops of the two bearing bars 76 respectively. The vertical plate 64 can increase the stability of the placement plate 6 when moving, and the bearing bars 76 can increase the stability of the movable plate 7 when moving; the setting of the vertical plate 64 and the bearing bars 76 can also reduce the weight borne by the telescopic end of the electric telescopic rod 8.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a fixing plate 62 is fixed to the first protective net 61, and a screw 63 is threaded onto the fixing plate 62. A screw hole adapted to the screw 63 is provided on the placement plate 6. The fixing plate 62 extends beyond the placement plate 6 so that when the first protective net 61 is placed in the groove on the placement plate 6, the fixing plate 62 can be fixed to the placement plate 6 using the screw 63, further improving the stability of the first protective net 61. This also facilitates the removal of the first protective net 61 from the groove by workers using the fixing plate 62.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, a short plate 73 extending above the movable plate 7 is fixed to the top of the second protective net 72. A screw 74, threaded onto the short plate 73 and connected to the movable plate 7, is threaded onto the short plate 73. A threaded hole matching the screw 74 is provided in the placement groove 71 on the movable plate 7. After the short plate 73 is fixed in the placement groove 71 by the screw 74, the stability of the second protective net 72 placed in the placement groove 71 is further increased. This also facilitates the removal of the second protective net 72 from the placement groove 71 by workers using the short plate 73.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
