Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of white cement processing, in particular to a white cement raw material anti-blocking negative pressure conveying system. BACKGROUND

[0002] The clinker rotary kiln system is equipped with a pre-decomposition furnace and a high-temperature fan, the high-temperature fan is a fan after a kiln tail preheater, is a power ventilation equipment of the whole kiln system, the heat exchange and gas-solid separation of the kiln system are adjusted by the power operation of the high-temperature fan, is a power source of the firing system, the kiln system and the preheater system, and the environmental negative pressure and airflow flow are driven by the high-temperature fan;

[0003] Since the net height of the high-temperature air pipe is 103 m and the drop is 100 m, the collapse of the high-temperature air pipe is a common problem in actual production of the kiln system, and the main reasons are as follows:

[0004] 1. The top bend of the high-temperature air pipe and the bend of the fan inlet are prone to material accumulation, and the material accumulation is too much to form self-weight collapse;

[0005] 2. When the raw material system is stopped, the atomizing water spray needs to be started to reduce the flue gas temperature, and the water spray cooling causes the material to adhere and bond to the pipe wall. When the raw material system is started, the flue gas temperature in the pipe rises from 230 DEG C to 360 DEG C, and the pipe wall accumulation collapses due to humidity and temperature change;

[0006] 3. The material accumulation at the inlet of the fan is prone to passive secondary collapse due to the impact of the upper pipe collapse, causing blockage or a large amount of material impacting the fan impeller.

[0007] Each collapse will produce hundreds of kilograms or even tons of accumulated blocks falling from a height of 77-100 m, and if the large blocks are not broken down during the falling process, they will directly impact the high-temperature fan impeller, causing the fan load to overload, the frequency converter to stop, or the fan dynamic balance to be damaged due to a large amount of material impacting the impeller, causing the vibration value to exceed the standard, the fan protection to stop, and the rotary kiln system interlock protection to stop, seriously affecting the operation reliability of the rotary kiln system.

Then the high temperature fan is upgraded and replaced, the fan efficiency is improved, and the whole machine is replaced, but the influence of the high temperature air pipe collapse on the high temperature fan has not been significantly improved.

[0041] After optimizing the preheater material accumulation forming factors and upgrading the high temperature fan, there is no effective prevention and control measure for the high temperature air pipe material accumulation problem, so the focus of the problem is changed from controlling material accumulation to optimizing the broken conveying of the collapse, reducing or even eliminating the influence of the collapse on the operation of the high temperature fan, so as to improve the reliability of the kiln system operation.

[0042] Therefore, the embodiment gives the following solution:

[0043] As Figures 1-10 shown, the white cement raw material anti-blocking type negative pressure conveying system comprises, in sequence, a rotary kiln, a preheater, a high-temperature air pipe 1, a high-temperature air fan, a raw material mill, a circulating air fan and a bag-type dust collector; a spraying frame 2 is installed at the top of the inside of the high-temperature air pipe 1, the bottom side wall of the high-temperature air pipe 1 is connected to the high-pressure air fan 5 through an inclined first air outlet pipe 51, the outlet of the high-pressure air fan 5 is connected to an inclined second air outlet pipe 52, and the inlet of the first air outlet pipe 51 is located at the top of the waste storage box.

[0066] The large block of white cement material adhered in the high-temperature air pipe 1 collapses and falls, and then the large block of white cement material is broken by the transverse rack 64 and the longitudinal rack 67 when contacting the main frame body, so that the large block of white cement material is converted into blocky and dispersed material; the dispersed material enters the fan with the flue gas, and the influence is very small; the blocky material falls into the buffer concave pit below after buffering, and is pulsed broken and dispersed by the air cannon 7 and then conveyed to the fan pipeline;

[0067] When it is necessary to clean the accumulated material in the settlement anti-blocking cavity 11, the first driving rod 33 drives the first baffle 331 to be retracted, the second driving rod 43 drives the second baffle 431 to be retracted, the main frame body is driven to rotate by the main driving motor 81, the first plug plate 684 rotates away from the first stop cover 323, and the second plug plate 695 rotates away from the second stop cover 423, after the main frame body rotates by 90°, the main frame body no longer interferes with the air jet pipe 71 below, then the traction assembly drives the main frame body to move downward, the cooperation of the guide strip 831 and the guide groove enables the main frame body to stably move vertically, when the main frame body descends to the settlement anti-blocking cavity 11, the worker can clean the main frame body thoroughly.

[0068] It is to be noted that, in the present text, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.
