Technical Field

The invention belongs to the technical field of cooling devices in the building material and chemical industry, and particularly relates to a water-cooled wall horizontal cement cooling device with a built-in spring.

Background

With the rapid development of infrastructure, construction sites of some important projects, such as airport runways, nuclear power plants, dam bridges and the like, have mandatory requirements on the use temperature of cement, and the temperature is generally below 60 ℃. However, the grinding process in cement production causes the grinding temperature of cement to be over 100 ℃ generally, and the overhigh temperature is the main reason for causing storage solidification and causing dehydration of gypsum, thereby affecting the quality and the construction performance of concrete. Therefore, the control of the cement temperature through the cooling process becomes one of the important indicators for measuring the quality of the cement.

At present, cement cooling equipment adopted by cement production plants mainly comprises a spiral lifting cooler and a water spraying device in a mill. The unit energy consumption of spiral lifting cooler is higher, and operating efficiency is lower, and equipment is bulky, adopts the extrinsic cycle water, and is higher to user's production place and technology arrangement requirement, and steam is direct to be arranged outward, is unfavorable for water conservation and environmental protection. Water spray in the mill is a cooling mode of direct heat exchange, the heat exchange efficiency is high, but parts such as a spray head are easy to block, the reliability of a water spray system is poor, and even production accidents are caused. Meanwhile, the quality of cement is affected by too large water spraying amount, and the cooling effect is affected by too small water spraying amount, so that the water spraying amount needs to be accurately controlled. For the reasons, the practical popularization and application effects of the two cement cooling devices are not ideal.

Example (b): a water-cooled wall horizontal cement cooling device with built-in springs is shown in figures 1-3 and comprises a support 13 for installation and a cylinder 11 arranged on the support;

a hollow shaft 5 is arranged in the cylinder, and one end of the hollow shaft is connected with a speed reducer 2 and a motor 1 to drive the hollow shaft to rotate;

the periphery of the hollow shaft is welded with a helical blade 6 and a lifting blade 7;

and the outer peripheral surface of the lower part of the cylinder body is provided with a water-cooled wall for cooling the material in the cylinder body.

The water cooling wall is formed by welding and arranging a plurality of brass thin-wall square tubes 12 together through fins 16, and two ends of each brass thin-wall square tube are respectively communicated with the water distribution bin 9 and the water collection bin 3. The square tube is made of brass materials and has a thin-wall structure, so that the heat resistance is favorably reduced, and the heat exchange efficiency is increased. The fins can increase the heat exchange area. The cooling water enters from a water distribution bin fixedly arranged at the discharge port of the cylinder body, is distributed to each brass thin-wall square tube, enters into a water collection bin fixedly arranged at the feed end of the cylinder body after heat exchange is completed along the cylinder body, and hot water discharged from the water collection bin is used for other purposes, so that the recycling of heat energy is realized.

A plurality of stainless steel springs 14 are arranged inside the brass thin-wall square tube 12. A gap is reserved between the spring and the wall surface of the square tube, and the ratio of the diameter of the spring to the side length of the square tube is 0.8. The spring moves under the impact of water flow, so that the inner layer flow and the boundary layer of the pipe are damaged, and the heat exchange effect is enhanced.

And an anti-scale ball is placed in the brass thin-wall square tube 12. The anti-scaling ball rolls in the square tube automatically under the action of the spring, so that the heat exchange effect is prevented from being influenced by scaling.

The material raising blades are arranged at equal intervals along the periphery of the hollow shaft. The hollow shaft in the cylinder is fixedly provided with the material raising blades at certain intervals, so that the accumulation of materials is reduced, and the heat exchange area between the materials and the wall surface of the cylinder is enlarged.

The working principle of the invention is as follows:

the helical blade drives the material to be pushed to the discharge hole, the material lifting blade reduces the accumulation of the material, and the heat exchange area between the material and the wall surface of the cylinder is enlarged. The water cooling wall welded by arranging and welding a plurality of brass thin-wall square tubes is welded on the circumferential surface of the lower part of the cylinder body, a plurality of stainless steel springs are arranged in the square tubes, and the springs move under the impact of water flow to form turbulent flow so as to enhance the heat exchange effect. The cooling water enters from a water distribution bin fixedly arranged at the discharge end of the cylinder body, is distributed to each water-cooling square tube, enters into a water collection bin fixedly arranged at the discharge end of the cylinder body after heat exchange is completed along the cylinder body, and hot water discharged from the water collection bin is used for other purposes, so that the recycling of heat energy is realized. The invention has the advantages of good cooling effect, simple structure, convenient operation and maintenance and the like, and can be used for efficiently cooling high-temperature materials in the building materials and chemical industry.
