Embodiment 1

[0030] Such as figure 1 , figure 2 , image 3 As shown, a soot sampling device for automatically positioning and measuring points, including a sampling nozzle 1, a fixing device 4, a PTFE shaft sleeve 5, a soot sampling tube 6, a sampling tube connector 7, a stepping motor 8, and a soot sampler The main engine 9, the screw rod 10, the fixed bearing part, the fixing device 4 includes a flange 16 connected with the sampling hole 3 arranged on the outer wall of the flue 2, and the middle of the fixing device 4 is embedded with a cylinder consisting of two semi-circular cylinders. The PTFE shaft sleeve 5, the dust sampling tube 6 is slidingly arranged in the polytetrafluoro shaft sleeve 5, the smoke sampling tube 6 is provided with a sampling nozzle 1 at one end, and a sampling tube connector 7 is fixed at the other end, and the sampling tube connector 7 includes a screw drive seat 24 with an internal thread, one end of the screw rod 10 is set in the screw drive seat 24, and th...

Embodiment 2

[0039] Such as Figure 4 As shown, the present embodiment also includes a flue hanging ring 11, a screw hanging ring 31 and a soft rope 12, the flue hanging ring 11 is arranged on the outer wall 2 of the flue, and the screw hanging ring 31 is arranged on the side of the screw mandrel 10 away from the stepping motor 8. At one end, the flue suspension ring 11 and the screw rod suspension ring 31 are connected by a soft rope 12 .

[0040] When using an extended or overweight smoke sampling pipe 6, if it is fixed only by the flange 16 of the fixing device 4 and the flange connection of the sampling hole 3, there is a possibility that the smoke sampling pipe 6 is not fixed firmly, the tail shakes or the tail droops. The fixing method of auxiliary hanging on the basis of flange fixing can be adopted, and the screw hanging ring 31 at the end of the screw rod 10 is connected with the flue hanging ring 11 on the outer wall 2 of the flue with a soft rope 12, and the pulling forc...

Embodiment 3

[0042] Such as Figure 5 As shown, this embodiment also includes a support frame 14 and a screw roller 32 , the bottom of the support frame 14 is set on the ground 13 , and the top is connected to the end of the screw 10 away from the stepper motor 8 through the screw roller 32 .

[0043] When using an extended or overweight sampling pipe, if it is only fixed by the flange connection between the fixture flange 16 and the sampling hole 3, there is a possibility that the smoke sampling pipe 6 may not be fixed firmly, the tail may shake or the tail may droop. The fixing method of auxiliary ground support on the basis of flange fixing, the upper end of the support frame 14 is connected and fixed on the end of the screw rod 10 away from the stepping motor 8 through the screw roller 32, so that the screw rod 10 is kept balanced, and the bottom of the support frame 14 is stable Fixed on the ground 13. Others are the same as in Example 1 and will not be described again.

Abstract

The invention discloses a sampling device of smoke and dust with automatically positioning detecting point, comprising a sampling mouth, a fixing unit, a Teflon axle sleeve, a sampling pipe of smoke and dust, a connecting piece of the sampling pipe, a stepping motor, a main engine of the sampling device of smoke and dust, a screw rod, and a rigid bearing unit, wherein, the fixing unit is connected with a sampling hole through a flange, the Teflon axle sleeve comprising two half circle cylinders are embedded in the center of the fixing unit, the sampling pipe of smoke and dust is slidingly arranged in the Teflon axle sleeve, one end of the sampling pipe of smoke and dust is provided with the sampling mouth, the connecting piece of the sampling pipe is fixed on the other end of the samplingpipe of smoke and dust, one end of the screw rod is arranged in a screw rod retainer, the other end of the screw rod is connected with the stepping motor through the rigid bearing unit arranged on the fixing unit, and the stepping motor is connected with the main engine of the sampling device of smoke and dust through signal lines and power lines. According to the invention, the whole process of sampling smoke and dust is accomplished automatically, so that the damage probability of operating personnel in operation process is reduced. The sampling mouth does not shake or incline when being used for positioning, the positioning is accurate and rapid, and the installation and dismounting of the sampling pipe are convenient.

Description

technical field [0001] The invention belongs to the technical field of smoke and dust monitoring in environmental monitoring, and more specifically relates to a smoke and dust sampling device for automatically locating and measuring points, which is suitable for sampling smoke and dust in fixed pollution sources. Background technique [0002] In the exhaust of fixed pollution sources such as flues, chimneys, and exhaust pipes (hereinafter referred to as flues), it is necessary to sample the particulate matter, that is, soot, and measure other flue gas parameters at the same time. Smoke sampling device is an important equipment for smoke sampling and determination of smoke parameters. [0003] When measuring flue gas parameters and sampling, in order to obtain representative samples, it is necessary to divide the flue section into an appropriate number of equal-area rings or squares, and divide the ring into two equal-area lines or square centers. as the measuring point. Th...
