Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sintered ore cooling, in particular to a cooling device for the air inlet of a circular cooling blower. Background Technique
[0002] In sintering production, the cooling of sintered ore is an important link in the sintering process. For a long time, the cooling of sintered ore has usually been forced cooling by natural air blown by a circular cooling blower. However, the problem with this traditional cooling method is that the temperature of the sintered ore is very high after coming out of the sintering machine, and the temperature of the natural air blown by the circular cooling blower increases after contacting the rotating impeller inside it. When the heated natural air contacts the sintered ore, the cooling effect is greatly weakened; therefore, in order to achieve the desired cooling effect, the cooling air volume needs to be increased, resulting in a relatively high power consumption of the circular cooling blower. Content of the Utility Model
[0003] The purpose of the utility model is to provide a cooling device for the air inlet of a circular cooling blower with reduced power consumption, so as to solve the problem of relatively high power consumption of the circular cooling blower proposed in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A cooling device for the air inlet of a circular cooling blower includes a silencer, an outward-expanded air inlet, and a cooling component. One end of the silencer is connected to the air inlet of the blower, and the other end is connected to the outward-expanded air inlet. The cooling component includes a cooling water network, which is arranged inside the outward-expanded air inlet. Both ends of the cooling water network are respectively provided with a water inlet and a water outlet extending outside the outward-expanded air inlet.
[0006] Preferably, the cooling water network includes several water pipes arranged in an S shape and connected end to end in sequence. The water pipes at both ends of the cooling water network are respectively connected to the water inlet and the water outlet.
[0007] Preferably, a flow monitoring device for detecting the water flow is arranged at the water outlet.
[0008] Preferably, the outward-expanded air inlet expands outward relative to the end connected to the silencer, and the diameter of the outward-expanded end of the outward-expanded air inlet is larger than the diameter of the end connected to the silencer.
[0009] Preferably, an isolation structure is arranged at the outward-expanded end of the outward-expanded air inlet, and the isolation structure includes an isolation net door arranged inside the outward-expanded air inlet.
[0010] Preferably, there are two isolation net doors, which are respectively hinged on the inner wall of the outward-expanded air inlet.
[0011] Preferably, a sunshade is provided at the top of the silencer, and one end of the sunshade extends above the outward-expanded air inlet and extends laterally outward of the outward-expanded air inlet.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. By arranging a cooling water network at the outward-expanded air inlet to cool the natural wind entering the silencer, the cooling water network includes a number of water pipes arranged in an S shape and connected end to end in sequence, so that the temperature of the natural wind passing through the silencer and entering the blower decreases. As the temperature of the natural wind decreases, the operating frequency of the blower can be reduced, thereby achieving the purpose of reducing power consumption;
[0014] 2. The outward-expanded air inlet expands relative to one end of the silencer, and the diameter of the outward-expanded end of the outward-expanded air inlet is larger than the diameter of the end where the outward-expanded air inlet is connected to the silencer. The outward-expanded air inlet with an increased diameter can install a larger-area cooling water network. Compared with the existing cooling device that can only be installed at the inlet end of the silencer, the larger-area cooling water network can cool more natural wind and improve the cooling effect of the natural wind;
[0015] 3. The two isolation net doors are net doors with a hollow shape and door frames, which are used to isolate foreign objects entering the outward-expanded air inlet inside the closed outward-expanded air inlet. When cleaning, only need to open the two isolation net doors outward relative to the outward-expanded air inlet, and the foreign objects on the two isolation net doors can be easily cleaned, avoiding the difficulty of cleaning caused by the negative pressure wind of the blower tightly adsorbing the foreign objects on the isolation net doors, improving the cleaning efficiency of the post personnel for foreign objects and reducing the cleaning difficulty of foreign objects, and the operation process is also simple and convenient.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1 - 3 , a cooling device for the air inlet of a ring cooler blower, including a silencer 1, an outward-expanded air inlet 2, and a cooling component 3. One end of the silencer 1 is connected to the air inlet of the blower (not shown in the figure), and the other end is connected to the outward-expanded air inlet 2. The cooling component 3 includes a cooling water network 301, which is arranged inside the outward-expanded air inlet 2. Both ends of the cooling water network 301 are respectively provided with a water inlet 302 and a water outlet 303 that extend outside the outward-expanded air inlet 2.
[0023] In this embodiment, the water inlet 302 is connected to the water pump of a cooling water tank, and the water outlet is connected to the cooling water tank to form a complete water cycle.
[0024] Please refer to Figure 2 , the cooling water network 301 includes several S-shaped water pipes that are connected end to end in sequence. The water pipes at both ends of the cooling water network 301 are respectively connected to the water inlet 302 and the water outlet 303.
[0025] In this embodiment, a temperature sensor is arranged inside the silencer 1. After the natural wind entering the silencer 1 through the outward-expanded air inlet 2 is cooled by the cooling water network 301, the temperature of the natural wind after cooling is monitored in real time through the temperature sensor. If the temperature drops to the preset temperature, the water flow rate in the cooling water network 301 remains unchanged. If the temperature sensor detects that the natural wind does not drop to the preset temperature, the water flow rate in the cooling water network 301 should be increased to achieve the preset cooling effect.
[0026] Preferably, a flow monitoring device 4 is arranged at the water outlet 303 for monitoring the water flow in the water pipe in real time, so as to adjust the parameters of the water pump in time to ensure the cooling effect of the cooling water network 301.
[0027] Please refer to Figure 1 , the outward-expanded air inlet 2 expands outward relative to one end of the silencer 1. The caliber of the outward-expanded end of the outward-expanded air inlet 2 is larger than the caliber of the end where the outward-expanded air inlet 2 is connected to the silencer 1. The outward-expanded air inlet 2 with an increased caliber can install a larger-area cooling water network 301. Compared with the existing cooling device that can only be installed at the inlet end of the silencer 1, the larger-area cooling water network 301 can cool more natural wind and improve the cooling effect of the natural wind.
[0028] Please refer toFigure 1 and Figure 3 , a separation structure 5 is provided at the outwardly expanded end of the outwardly expanded air inlet 2, and the separation structure 5 includes a separation net door 501 disposed inside the outwardly expanded air inlet 2. In this embodiment, there are two separation net doors 501, which are respectively hinged on the inner wall of the outwardly expanded air inlet 2. The two separation net doors 501 are hollow-shaped net doors with door frames. In cooperation with the closed outwardly expanded air inlet 2, they are used to isolate foreign matters entering the outwardly expanded air inlet 2, such as leaves and other sundries. When cleaning, only need to open the two separation net doors 501 outward relative to the outwardly expanded air inlet 2, and the foreign matters on the two separation net doors 501 can be easily cleaned, avoiding the difficulty of cleaning caused by the negative pressure air of the blower tightly adsorbing the foreign matters on the separation net door 501, improving the cleaning efficiency of the post personnel for foreign matters and reducing the cleaning difficulty of foreign matters, and the operation process is also simple and convenient.
[0029] Please refer to Figure 1 , preferably, a sunshade 6 is provided at the top of the silencer 1, and one end of the sunshade 6 extends above the outwardly expanded air inlet 2 and extends laterally to the outwardly expanded air inlet 2. The sunshade 6 can prevent rainwater from entering the silencer 1 along with the air on rainy days and causing corrosion to the silencer 1 and the internal structure of the blower.
