Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically a safety protection device for cement production. Background Technology

[0002] Cement, a powdered hydraulic inorganic binder, forms a paste when mixed with water. It hardens in air or, even better, in water, and can firmly bind materials such as sand and stone together. Early mixtures of lime and volcanic ash were very similar to modern lime-volcanic ash cement. Concrete made by binding crushed stone with cement not only has high strength after hardening but also resists erosion from fresh or salt water. For a long time, it has been widely used as an important binder in civil engineering, water conservancy, national defense and other projects.

[0003] Most existing liquid level measurement devices use electronic equipment to detect and report the material level in the silo. However, during liquid level measurement in cement silos, the large amount of dust can easily corrode the electronic devices, and these devices have a high failure rate. Sudden malfunctions can lead to untimely monitoring of the cement silo level and the inability to replace the detection equipment promptly. This can result in overfilling of the cement silo, causing material to overflow, and the accumulation of cement on the surface during equipment replacement can cause cement spillage, impacting the factory environment. Therefore, we provide a safety protection device for cement production to solve these problems. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a safety protection device for cement production.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for cement production, comprising a cement discharge tank, an equipment conversion chamber at the bottom of the cement discharge tank, a baffle plate inserted inside the end of the equipment conversion chamber away from the cement discharge tank, an equipment adjusting wheel rotatably connected inside the equipment conversion chamber, a rotating groove meshing with both ends of the equipment adjusting wheel on the inner wall of the equipment conversion chamber, two cement flow chambers arrayed inside the equipment adjusting wheel, a detection module fixedly connected inside the cement flow chamber by bolts, limit rails fixedly connected to the upper and lower sides of the detection module on the inner wall of the cement flow chamber, an air inlet pipe connected through the top of the equipment conversion chamber, and a residual material collection pipe connected through the bottom of the equipment conversion chamber.

[0008] Furthermore, a cement feed pipe is connected through the top of the cement discharge tank, and an observation window is provided on the bottom outer wall of the cement discharge tank near the equipment conversion chamber.

[0009] Furthermore, a drive wheel is fixedly connected to the rear end of the device's adjusting wheel, a power wheel is engaged at the top of the drive wheel, a servo motor is fixedly connected to the rear end of the power wheel, and the outer wall of the servo motor is connected to the outer wall of the cement discharge tank through a bracket.

[0010] Furthermore, the cement flow chamber is opened in a 180-degree fan shape, and the detection module at one end of the equipment adjustment wheel extends into the cement discharge tank.

[0011] Furthermore, a groove is provided at the center of the detection module, and a bolt is placed in the groove. The side wall of the detection module is slidably connected to the limiting rail, and the side wall of the detection module is in contact with the inner wall of the cement flow chamber.

[0012] Furthermore, the air inlet pipe and the residual material collection pipe are respectively installed on the upper and lower sides of the cement flow chamber. The air inlet pipe is connected to the external air blowing mechanism, and the residual material collection pipe is connected to the external collection mechanism.

[0013] (iii) Beneficial effects:

[0014] Compared with existing technologies, this safety protection device for cement production has the following advantages:

[0015] I. This utility model uses a detection module to detect the flow rate of cement in a cement discharge tank. When the detection module needs to be replaced, the servo motor drives the power wheel to rotate twice, which in turn drives the drive wheel to rotate. Each rotation of the power wheel causes the drive wheel to rotate 90 degrees. The drive wheel moves the detection module to be replaced to one side of the baffle plate, while the new detection module is inserted into the cement discharge tank. The detection module can be replaced by removing the baffle plate. This solves the problem of high failure rate of electronic equipment in existing cement level measuring devices and the inability to replace detection equipment in a timely manner, which causes excessive material feeding into the cement silo and material overflow. It has the advantage of replacing detection equipment without stopping the machine.

[0016] Second, the external blowing mechanism of this utility model blows air into the cement flow chamber through the air inlet pipe. The cement residue in the cement flow chamber is discharged through the residual material collection pipe, which solves the problem of cement scattering caused by the accumulation of a large amount of cement on the surface when changing the testing equipment. It has the advantage of dust reduction. Attached Figure Description
