[0002] In the process of storing powder in the silo, the powder will generate heat accumulation due to various factors (such as ambient temperature, self-chemical reaction, etc.), resulting in the increase of temperature in the silo. However, most of the existing silo facilities lack effective cooling means, and it is difficult to timely and effectively regulate the temperature of the powder in the silo. The high-temperature environment not only affects the quality and performance of the powder, but also may cause the deterioration and caking of the powder, thereby affecting the subsequent production and use and causing economic losses to the enterprise.

[0023] In use, the water pump is started, the water in the external water pipe is introduced into the annular connecting water pipe 10 through the water inlet pipe 7, and then is distributed to each water distribution pipe 11, sprayed from the water spray head, and used to cool the powder at the upper part of the silo body 1, the sprayed water falls into the water distribution hopper 6, and then flows into the water receiving hopper 2, and finally is discharged through the drain pipe 5, the plug-in temperature sensor 15 monitors the temperature of the powder in the silo body 1 in real time, the patch type temperature sensor monitors the temperature of the powder in the discharge hopper 4 in real time, and transmits the data to the control system, so that the operator can know the temperature of the powder in time.

[0024] Embodiment two: please refer to Figure 1 、 Figure 2 and Figure 3 , the installation process is similar to that of embodiment one, the silo body 1 is fixed first, when the support frame 8 is installed, the support frame 8 is made of appropriate material according to the size and bearing requirement of the silo body 1, so that it can stably support the components such as the water distribution pipe 11, the number and spacing of the water distribution pipes 11 can be adjusted according to the diameter of the silo body 1, so as to ensure that the water sprayed from the water spray head can uniformly cover the entire upper area of the silo.

[0025] The connection between the annular connecting water pipe 10 and the water distribution pipe 11 should be sealed well to prevent water leakage, a valve can be installed at the connection between the water inlet pipe 7 and the external water pipe, so as to control the size and start-stop of the water flow, the size of the water distribution hopper 6 and the water receiving hopper 2 can be appropriately enlarged according to the specification of the silo body 1, so as to improve the water receiving and drainage capacity.

[0026] The installation of the discharge hopper 4 needs to ensure that it is tightly connected with the silo body 1 to prevent powder leakage. The installation position of the plug-in type temperature sensor 15 can be adjusted according to actual needs, and the patch type temperature sensor can also be installed at the corresponding place of the inner wall of the discharge hopper 4 according to actual needs, so that it can accurately measure the temperature of the powder in the silo body 1 and the temperature of the powder inside the discharge hopper 4. Since the discharge hopper 4 may also be installed with components of a conveying auger, the patch type temperature sensor installed on the inner wall of the discharge hopper 4 will not affect the work of the auger. The material of the protective plate 3 can be selected from wear-resistant and corrosion-resistant materials to improve its service life. The fixing bolts of the limiting plate 13 and the silo body 1 need to be checked regularly to ensure firm connection.

[0027] In use, by setting appropriate water spraying time and amount through the control system, and according to the temperature data fed back by the temperature sensor 15, the operation of the water pump is automatically adjusted to realize accurate control of the temperature of the powder in the silo. Then, materials such as concrete powder, cement, mineral powder, fly ash, and silica ash are added into the silo body 1 through the feeding pipe 9. At this time, the materials will fall into the silo body 1 and the discharge hopper 4 under the action of gravity. At this time, the temperature sensor 15 will not be impacted but the protective plate 3 will be impacted under the protection of the protective plate 3, thereby achieving the purpose of protecting the temperature sensor 15. After the addition of the materials is completed, the connecting bolts between the limiting plate 13 and the silo body 1 can be removed, and the protective plate 3 can be pulled out of the silo body 1 through the pull plate 14, so that the temperature sensor 15 is exposed. At this time, the purpose of measuring the temperature of the materials in the silo body 1 through the temperature sensor 15 can be achieved. When the protective plate 3 is pulled out of the silo body 1, it does not need to be pulled out completely, but only needs to expose the temperature sensor 15.

[0028] Implementation effect: By uniformly installing multiple water distribution pipes 11 with inclined water spraying heads outside the top support frame 8 of the silo body 1, and connecting the water distribution pipes 11 with the external water pipe through the top annular connecting water pipe 10 and the left water inlet pipe 7, uniform water spraying and cooling in the silo can be achieved. The water collected by the water distribution hopper 6 flows into the water receiving hopper 2 and then is discharged through the drain pipe 5, forming a complete water circulation cooling system, which can effectively reduce the temperature of the powder in the silo and ensure the quality of powder storage.

[0029] By opening the mounting hole on the sidewall of the silo body 1 and fixing the temperature sensor 15, the powder temperature in the silo body 1 can be monitored in real time and accurately, and the patch type temperature sensor installed on the inner wall of the discharge hopper 4 can monitor the powder temperature in the discharge hopper 4, so as to provide accurate data for the operator to adjust the cooling measures in time, and meanwhile, the semicircular protective plate 3 is arranged on the upper part of the temperature sensor 15, which is inserted into the silo body 1 through the through hole, and the external limiting plate 13 and the bolt are fixed, and the through hole is sealed by the rubber ring, so that the temperature sensor 15 can be effectively protected from the impact and wear of the powder, and the pull plate 14 facilitates the insertion and pulling out of the protective plate 3 from the silo body 1.
