[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model more clear and understandable, the present utility model will be further described in detail in combination with embodiments and drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. The technical solutions of the present utility model will be described in detail below in combination with embodiments and drawings, but the protection scope is not limited by this.

[0021] As Figure 1 —4 shows, the present utility model provides a bulk shipping equipment on the side of a cement silo, which is arranged on one side of the cement silo 1 and includes a fixed frame 2, a dust collector 3, a manual gate valve 17, a pneumatic gate valve 18, an electric flow valve 19, a vibrating screen 4, and a bulk loader 15.

[0022] The fixed frame 2 includes an upper layer and a lower layer. The lower layer of the fixed frame 2 is arranged on the ground on one side of the cement silo 1. A dust collector 3 is fixedly arranged at one end of the lower layer of the fixed frame 2 away from the cement silo 1. The upper end of the dust collector 3 is an inlet, and the lower end of the dust collector 3 is an outlet.

[0023] A vibrating screen 4 is fixedly arranged on the upper layer of the fixed frame 2 between the dust collector 3 and the cement silo 1. The vibrating screen 4 includes a base 5 of the vibrating screen, a vibrating housing 6, a vibrator 7, a screen mesh, and a chute 8.

[0024] The base 5 of the vibrating screen is a horizontally arranged square ring structure and is fixedly arranged on the upper layer of the fixed frame 2. A vibrating housing 6 is arranged on the upper end of the base 5 of the vibrating screen. The vibrating housing 6 is a housing with an open lower end. The upper end surface of the vibrating housing 6 includes a horizontal plane and an inclined plane. The inclined plane slopes downward at the end facing the dust collector 3; a feed inlet 9 is arranged at the horizontal plane, a dust collection pipe interface 10 is arranged on the inclined plane, and a vibrator 7 is fixedly arranged at the upper end of the inclined plane. The operation of the vibrator 7 drives the vibrating housing 6 to vibrate on the base 5 of the vibrating screen.

[0025] Inside the vibrating housing 6, a sieve is fixedly arranged, and the sieve is located below the feed inlet 9 and the dust collection pipe interface 10. The sieve slopes downward on the side facing the dust collector 3; at the four corners of the lower end of the sieve, a spring is respectively arranged, and the upper and lower ends of the spring are fixedly connected to the sieve and the inner wall of the vibrating housing 6 respectively. On the side wall of the vibrating housing 6 close to the dust collector 3, a particulate discharge port 11 is arranged, and the particulate discharge port 11 is located at the downward-sloping end of the sieve. At the particulate discharge port 11, a vertically downward particulate discharge pipe 12 is fixedly arranged, and the particulate matter screened by the sieve is discharged outwards through the particulate discharge pipe 12.

[0026] At the lower end of the vibrating screen base 5, a chute 8 is fixedly arranged. The chute 8 is a horn-shaped structure that is thick at the top and thin at the bottom. The upper end inlet of the chute 8 is fixedly connected to the lower end of the vibrating screen base 5. Below the lower end outlet of the chute 8, a bulk loader 15 is arranged, and the inlet of the bulk loader 15 is communicated with the lower end outlet of the chute 8 through a connecting pipe.

[0027] The dust collection pipe interface 10 at the upper end of the vibrating housing 6 is communicated with the inlet at the upper end of the dust collector 3 through a dust collection pipe 13, and the outlet at the lower end of the dust collector 3 is communicated with the inlet of the bulk loader 15 through a return dust chute 14.

[0028] On the side of the cement silo 1 facing the dust collector 3, a side outlet is arranged. At the side outlet, an obliquely downward discharge chute 16 is fixedly arranged, and the discharge chute 16 is communicated with the feed inlet 9 at the upper end of the vibrating housing 6. At the outlet of the discharge chute 16, a manual gate valve 17, a pneumatic gate valve 18, and an electric flow valve 19 are arranged in sequence.

[0029] The working principle of the present utility model is as follows:

[0030] The cement material inside the cement silo 1 is output to the inside of the vibrating screen 4 through the discharge chute 16 at the side outlet. The manual opening and closing of the discharge chute 16 can be realized through the manual gate valve 17, the automatic opening and closing of the discharge chute 16 can be realized through the pneumatic gate valve 18, and the control of the amount of cement material output inside the discharge chute 16 can be realized through the electric flow valve 19.

[0031] The cement material entering the inside of the vibrating screen 4 drops onto the screen mesh. Due to the operation of the vibrator 7, the vibrating housing 6 and the screen mesh vibrate synchronously, causing the cement material on the screen mesh to roll towards the downwardly inclined end of the screen mesh. During the rolling process of the cement material on the screen mesh, screening is carried out. The cement material with small particle size drops through the screen mesh into the chute 8 and finally enters the bulk loader 15 through the chute 8. The large particle size particulate matter finally discharges outward through the particulate matter discharge pipe 12 after rolling on the screen mesh. The mixture of dust and air enters the dust collector 3 through the dust collection pipe 13. After the air is filtered, it discharges to the outside of the dust collector 3. The cement ash is collected and finally output to the inside of the bulk loader 15 through the dust return chute 14 at the lower end of the dust collector 3.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
