Description

Technical Field

[0001] This utility model relates to the field of cement production technology, and specifically to a grinding aid flow controller for cement production. Background Technology

[0002] The cement production process is often referred to as "two grindings and one calcination," namely raw material grinding, kiln calcination, and cement grinding. Among these, cement grinding is the most energy-intensive process. When the cement fineness reaches a certain level, the agglomeration of fine particles causes a decrease in cement classification efficiency, leading to a deterioration in grinding conditions and a sharp drop in grinding efficiency. To improve grinding conditions, one method is to add cement grinding aids during the grinding process. Adding grinding aids to the mill can significantly improve the grinding process and increase the hourly output of the cement mill. Existing cement grinding aids are mainly divided into two categories: solid and liquid. Solid grinding aids often cause blockages in the flow controllers of the pipeline. After the flow controller is blocked, it needs to be disassembled and cleared, which is very troublesome. Frequent disassembly not only increases the workload, but also increases leakage between the pipeline and the flow controller due to frequent disconnection, posing a problem. Utility Model Content

[0003] In view of the deficiencies in the existing technology, this utility model provides a flow controller for grinding aids in cement production to solve the existing problems.

[0004] This utility model is achieved through the following technical solution: a flow controller for grinding aid in cement production, comprising a housing, characterized in that: a feed pipe is fixedly connected to the housing, a discharge pipe is fixedly connected to the bottom of the housing, a cylinder is fixedly connected to the housing, a mounting bracket is fixedly connected to the piston rod of the cylinder, a column is fixedly connected to the mounting bracket, the column is slidably connected to the housing, a pressure block is fixedly connected to one end of the column, the pressure block is slidably connected to the housing, a connecting rod is slidably connected inside the pressure block, and a sealing block is fixedly connected to one end of the connecting rod.

[0005] Preferably, a threaded pipe is rotatably connected to the outer shell via a bearing, a screw is threadedly connected to the threaded pipe, one end of the screw is fixedly connected to a connecting rod, the sealing block is fixedly connected to a sliding rod via an adapter, the sliding rod is slidably connected to the discharge pipe, and one end of the sliding rod is fixedly connected to a limiting block.

[0006] Preferably, a second gear is fixedly connected to the outer wall of the threaded tube, the second gear meshes with the first gear, the first gear is fixedly connected to the shaft of the servo motor, and the servo motor is fixedly connected to the outer casing.

[0007] Preferably, the outer shell has a through hole, the bottom through hole is funnel-shaped, and the inner opening of the discharge pipe is funnel-shaped.

[0008] Preferably, the pressing block is frustum-shaped and the sealing block is frustum-shaped.

[0009] The beneficial effects of this utility model are reflected in the following: the opening between the discharge pipe and the sealing block is controlled by a servo motor, making the flow control more precise. At the same time, a pressure block is set inside the outer shell to clean the pipe wall residue. The funnel structure design inside the outer shell and the discharge pipe makes it less likely for residue to remain, reducing blockage. Attached Figure Description

However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0019] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations.
