Description

Technical Field

[0001] The utility model relates to the technical field of cement production equipment, in particular to an automatic ash cleaning device for the gas sampling probe of a high-temperature gas analyzer at the kiln tail of a cement plant. Background Art

[0002] The rotary kiln is the most important production equipment in the cement industry, responsible for the function of clinker calcination. The operation efficiency and state of the rotary kiln directly affect the output and quality of cement clinker. The exhaust gas components generated after internal calcination in the rotary kiln can reveal the calcination state. The high-temperature gas analyzer in the kiln tail smoke chamber is used to online analyze the content of the kiln tail flue gas. Operators can appropriately adjust the proportion of air and coal according to the change of the flue gas content, so as to achieve a stable calcination state, save energy and reduce consumption;

[0003] For example, in the prior art, the patent with the authorization announcement number of CN217033821U discloses a high-temperature fixed probe for a self-cleaning kiln tail gas analyzer. The lower connecting rod and the detection head are driven by a pneumatic pump to move along the sliding rod into the rotary kiln for gas sampling detection. When not in use, the lower connecting rod and the detection head can use the compressed air in the air storage tank to withdraw the detection head into the smoke chamber, and the gas in the lower connecting rod and the detection head is pumped out through the gas detection module, stored and then subjected to subsequent detection and analysis;

[0004] However, this device cannot cool down the detection head when it extends into the rotary kiln to sample and detect gas. The probe is in a high-temperature state, which affects its service life. Moreover, when the probe extends into the rotary kiln to sample gas, the dust in the gas will adhere to the detection head. The cement dust in the cement production process is corrosive. If not cleaned in time, it is easy to cause corrosion damage to the detection head. Therefore, an automatic ash cleaning device for the gas sampling probe of a high-temperature gas analyzer at the kiln tail of a cement plant is designed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the above background art, and to propose an automatic ash cleaning device for the gas sampling probe of a high-temperature gas analyzer at the kiln tail of a cement plant.

[0006] The technical problem to be solved by the utility model is to provide an automatic ash cleaning device for the gas sampling probe of a high-temperature gas analyzer at the kiln tail of a cement plant, so as to solve the problems in the prior art that the probe of the gas analyzer cannot clean the dust attached to the detection head and cannot cool down the detection head in time.

The gas analyzer is installed at the tail of the cement rotary kiln through a mounting plate, and a through hole matching the sampling probe is opened in the direction directly opposite to the sampling probe at the tail of the cement rotary kiln.

Moreover, the corrugated telescopic pipe can be disassembled between the suction pipe and the sampling probe, facilitating the cleaning of the dust inside the corrugated telescopic pipe, and the operation is simple and convenient.

[0027] As Figures 1 - 4 shown, the embodiment of the present utility model provides an automatic ash cleaning device for the gas sampling probe of the tail-end high-temperature gas analyzer in a cement plant, which includes a mounting plate 1, a gas analyzer 2, a suction pipe 3, a corrugated expansion pipe 4 and a sampling probe 5.

A probe cleaning assembly is fixedly arranged on the right side of the upper surface of the mounting plate 1.

[0028] In this embodiment, the mounting plate 1 is installed at the tail end of the cement rotary kiln, and a through hole matching the sampling probe 5 is opened on the tail end of the cement rotary kiln, which is convenient for the sampling probe 5 to extend into the tail end of the rotary kiln to collect gas.

[0029] In this embodiment, the cleaning assembly includes a column 8, an annular box 801, spraying holes 802, a water inlet pipe 803 and a gelatinous hose 804.

[0030] In this embodiment, the other end of the gelatinous hose 804 is sleeved on the tap water pipe, and the tap water pipe provides water source for the annular box 801.

[0031] In this embodiment, the diameter of the central through hole of the annular box 801 is larger than the diameter of the sampling probe 5, and the annular box 801 is sleeved on the sampling probe 5.

[0032] In this embodiment, there are 12 - 16 water spray holes 802, and the water spray holes 802 are evenly distributed on the inner surface of the annular box 801, facilitating the water sprayed by the water spray holes 802 to be evenly sprayed on the sampling probe.

[0033] By providing the corrugated telescopic tube 4 and the electric telescopic rod 6, the gas analyzer is installed at the tail of the cement rotary kiln through the mounting plate 1, and a through hole matching the sampling probe 5 is opened in the direction directly opposite to the sampling probe 5 at the tail of the cement rotary kiln. When sampling the gas at the tail of the cement rotary kiln, the electric telescopic rod 6 extends to drive the sampling probe 5 to extend into the tail of the cement rotary kiln. The high-temperature gas at the tail of the cement rotary kiln enters the gas analyzer 2 through the sampling probe 5, the corrugated telescopic tube 4, and the suction pipe 3 for gas analysis after sampling. After sampling is completed, the electric telescopic rod 6 contracts, causing the sampling probe 5 not to extend into the tail of the cement rotary kiln, preventing the sampling probe 5 from always being in the tail of the cement rotary kiln and preventing the high temperature in the tail of the cement rotary kiln from damaging the sampling probe 5, ensuring the service life of the sampling probe 5;

[0034] By providing a cleaning component, during the process of the sampling probe 5 extending into the tail of the cement rotary kiln for gas sampling, the tap water source connected to the rubber hose 804 is turned on. The tap water enters the annular box 801 through the rubber hose 804 and the water inlet pipe 803 and sprays out from the water spray holes 802, spraying on the outer surface of the sampling probe 5, achieving the effect of cooling the sampling probe 5 and preventing the sampling probe 5 from being damaged due to excessive temperature during sampling;

[0039] With the dredging rod 302, when the sampling probe 5 extends into the tail of the cement rotary kiln for gas sampling, the electric telescopic rod 6 is in its maximum telescopic state. At this time, the dredging rod 302 is at the left end of the sampling probe 5, and the dredging rod 302 will not block the sampling probe 5, facilitating the normal sampling of the sampling probe 5. When the probe stops sampling, the electric telescopic rod 6 drives the sampling probe 5 to contract, causing the sampling probe 5 to move to the left. The dredging rod 302 penetrates through the sampling probe 5, achieving the effect of dredging the sampling probe 5 and preventing the sampling probe 5 from being blocked by cement dust. Moreover, the corrugated telescopic pipe 4 can be disassembled between the air extraction pipe 3 and the sampling probe 5, facilitating the cleaning of the dust inside the corrugated telescopic pipe 4, and the operation is simple and convenient.

[0040] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
