Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a vertical spiral cement cooler with a spray device. Background Art

[0002] At present, domestic cement grinding mostly adopts ball mill. According to calculation, about 80% of the energy in the grinding process is converted into heat, and the cement temperature is high. Generally, the temperature of cement out of the mill is 100℃~130℃. After transportation and storage, the cement will have a temperature of 80℃~85℃ when it leaves the factory. Cement will generate heat during the hydration process. If the initial temperature is relatively high, it will cause the slump of concrete to increase, the water-cement ratio to increase, and the strength to decrease. Users generally require the cement temperature to be below 70℃. In view of the increasing requirements of users for cement temperature and cement quality, cement cooling equipment is widely used by cement companies. Through investigation, it is found that the cement cooling equipment currently used online is mostly vertical spiral lifting spiral cement cooler (hereinafter referred to as cement cooler). In order to improve the cooling effect of cement cooler, this water cooling device is added on the basis of the original cement cooler structure. The device increases the heat exchange area of ​​the cement cooler shell by spraying water through auxiliary nozzles, and improves the cooling efficiency of the cement cooler.

[0003] The authorization announcement number in the prior art is: CN201753324U, and the name is: a horizontal spiral cement cooler, which consists of a support, a horizontal cylinder, a hollow shaft, a hollow spiral blade, a water spraying pipe and a cooling water trough. The support firmly supports the horizontal cylinder, and the hollow shaft is rotatably installed in the cylinder. The characteristic of this hollow shaft is that its outer circumference is provided with hollow spiral blades that are interconnected with it. This design not only increases the cooling area, but also improves the cooling efficiency. Several water spraying pipes are provided above the cylinder, which can evenly spray cooling water on the material in the cylinder, thereby further accelerating the cooling speed, and the cooling water trough arranged below the cylinder can immerse the entire cylinder, and the cooling effect is further improved through heat exchange between water and the cylinder. However, this patent easily brings water out of the cooling water trough during cooling, and water needs to be added subsequently, resulting in poor cooling effect, and excess heat cannot be collected and utilized, resulting in high cost.

[0004] The application publication number in the prior art is: CN101891061A, and the name is: a horizontal spiral cement cooler, which consists of a support, a horizontal cylinder, a hollow shaft, a hollow spiral blade, a water spraying pipe and a cooling water tank. When the device is working, the hollow shaft and the spiral blade rotate in the cylinder, and the material rises with the spiral blade. At the same time, the water spraying pipe sprays cooling water to enhance the cooling effect. The cooling water tank under the cylinder further improves the cooling efficiency through heat exchange between water and the cylinder. The patent has a simple structure, stable operation, good cooling effect, simple operation and maintenance, and low cost. It is suitable for various industries that need to handle powdered high-temperature materials, such as chemical industry, metallurgy, building materials, etc., to achieve efficient cooling. However, this patent has the same problem as the above patent, and the cooling effect is poor. Summary of the invention

DETAILED DESCRIPTION

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] like Figure 1~Figure 5 As shown, this embodiment proposes a vertical spiral cement cooler with a spray device, including a base 1, the top of the base 1 is fixedly connected to a box body 8 by bolts, a barrel 15 is arranged inside the box body 8, a motor is installed at the bottom of the barrel 15, the output end of the motor is fixedly connected to a coaxially arranged spiral blade 17 through a coupling, a feed pipe 14 and a discharge pipe 13 are respectively arranged on the barrel 15, a spray assembly is arranged inside the box body 8, the top of the base 1 is fixedly connected to a fixing frame 6 by bolts, a circulating water pipe 11 is arranged inside the fixing frame 6, and the top of the base 1 A water tank 3 is provided at the bottom, a water pump 5 is installed on one side of the water tank 3, the output end of the water pump 5 is connected to the circulating water pipe 11, and a power distribution cabinet 2 is installed on the top of the base 1. Through the arrangement of structures such as spiral blades and nozzles 16, the raw materials to be cooled are pushed from bottom to top through the spiral blades 17, and the water sprayed by the nozzles 16 slides evenly on the surface of the material barrel 15, thereby cooling. The water outlet 10 is located above the bottom of the box body 8, so that a part of water will remain at the bottom of the box body 8, so that the lower part of the cooling cylinder is immersed in water at a lower temperature, thereby achieving sufficient heat exchange and better cooling effect.

[0028] like Figure 1~Figure 5 As shown, the spray assembly includes a sprinkler device 25 and a water pipe, and the water pipe is respectively provided with a water outlet 1 24, a water outlet 2 18, a water outlet 3 19, a water outlet 4 20, a water outlet 5 21, a water outlet 6 22 and a water outlet 7 23.

[0029] like Figure 1 As shown, a connecting pipe 4 is provided on one side of the water tank 3 , a water outlet 10 is provided at the bottom of the tank body 8 , and the connecting pipe 4 is fixedly connected to the water outlet 10 .

[0030] like Figure 1 As shown, a fixed block is installed on one side of the circulating water pipe 11, and one end of the circulating water pipe 11 passes through the interior of the fixed block. A water inlet 9 is provided on one side of the box body 8, and the circulating water pipe 11 is fixedly connected to the water inlet 9.

[0031] like Figure 2 As shown, two through holes are opened inside the box body 8, and the feed pipe 14 and the discharge pipe 13 both pass through the inside of the through holes.

[0032] like Figure 2 As shown, a plurality of nozzles 16 evenly distributed around the circumference are arranged inside the box body 8 , and the nozzles 16 surround the barrel 15 .

[0033] In this embodiment, the raw material is first transported to the inside of the barrel 15 through the feed pipe 14, and then the motor drives the spiral blade 17 to rotate to push the raw material upward. The nozzles 16 around the inside of the box 8 spray water, so that a uniform and stable water curtain flows down the surface of the barrel 15 for cooling. In order to improve the cooling effect, the water outlet 10 is set slightly above the bottom of the box 8, so that the lower part of the cooling cylinder is immersed in water at a lower temperature to achieve sufficient heat exchange, thereby achieving better cooling effect. Then the raw material is sent out from the discharge port. The spray device effectively improves the cooling efficiency of the cement cooler. It can be turned on and off at any time through the electronic control system. The operation process is simple. The spray device borrows the original water supply pipeline and connects a branch pipe separately at the upper part. The cooling nozzle 16 is connected through a valve. The position of the nozzle 16 is adjusted to spray evenly on the upper surface of the cement cooler to increase the heat exchange area of ​​the equipment.

Through the arrangement of structures such as the thermal battery 7 and the fan 12, water will have residual heat after cooling, so that when the water passes through the circulating water pipe 11, the heat is blown to one side through the fan 12, so that the thermal battery 7 can store energy, which is convenient for continued use in subsequent power outages, thereby saving costs.

[0035] like Figure 1 As shown, a bracket is provided on the top of the base 1, and the thermal battery 7 is installed on the top of the bracket.

[0036] In this embodiment, since the water is circulated and cooled, there will be residual heat in the water after cooling, so that the water passes through the circulating water pipe 11 and the heat is blown to one side by the fan 12, so that the thermal battery 7 can store energy, which is convenient for continued use in subsequent power outages, thereby saving costs.
