[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0031] like Figure 1-8 As shown, the dust removal vibrating feeder proposed in this utility model includes a fixed frame 1-1, a vibrating rigid body 1-2 is provided on the upper part of the fixed frame 1-1, and a centrifugal fan 1-3 is provided on the side.

[0032] The vibrating rigid body 1-2 includes a conveying trough 1-2-3 and a vibrating motor 1-2-5 installed on its outside. A stainless steel screen plate 1-2-6 with screen holes is laid at the bottom front end of the conveying trough 1-2-3. A cover plate 1-2-7 is installed above the stainless steel screen plate 1-2-6. An exhaust port 1-2-2 and a feed port 1-2-4 are welded to both ends of the cover plate 1-2-7, respectively. An air supply pipe 1-2-1 is installed in the interlayer between the conveying trough 1-2-3 and the stainless steel screen plate 1-2-6. The air supply pipe 1-2-1 and the centrifugal fan 1-3 are connected by a flexible air outlet 1-6.

[0033] Above the stainless steel sieve plate 1-2-6, there is an exhaust device 1-4 installed on the fixed frame 1-1. The exhaust device 1-4 includes a box 1-4-4 connected to the exhaust port 1-2-2 through the exhaust port flexible connection 1-5. The exhaust device 1-4 can be raised and lowered along the installation position.

[0034] In this embodiment, the material enters the vibrating rigid body 1-2 through the feed inlet 1-2-4 and is conveyed forward under the vibration drive of the vibrating motor 1-2-5. The positive pressure air generated by the centrifugal fan 1-3 passes through the blower flexible connection 1-6 and the air supply pipe 1-2-1 from bottom to top, penetrating the screen holes of the stainless steel screen plate 1-2-6. The airflow mixes with the material at the screen plate, raising light dust and preventing the material from passing through the screen holes. The raised dust, under the negative pressure suction of the fan, is carried by the airflow through the exhaust port 1- 2-2. The exhaust port flexible connection 1-5 leads to the exhaust device 1-4, and finally discharges into the external dust removal system from the top outlet 1-4-3. The clean metal material is then conveyed to the discharge end and enters the downstream vortex separator. It integrates the functions of blowing, screening and exhaust, and handles dust in a timely manner during the conveying process, improving the working environment. Moreover, each component is effectively protected from vibration by the centrifugal fan 1-3, the exhaust device 1-4 and the external pipeline through the design of rubber springs and flexible connections, making the operation reliable and convenient.

[0035] It is understandable that the flexible air connector 1-6 connects the air outlet of the centrifugal fan 1-3 and the air supply duct 1-2-1 of the vibrating rigid body 1-2, which is usually a rubber hose;

[0036] The flexible connection 1-5 connects to the exhaust port 1-2-2 of the rigid body 1-2 and the housing 1-4-4 of the exhaust device 1-4, which are usually made of flexible materials such as canvas.

[0037] Centrifugal fans 1-3 provide dust removal air pressure and air volume. The model is Y90S-2 (power 2.2kw, flow rate 1688-3517m³ / h). Two fans are set up to form a dual-channel structure.

[0038] It should be noted that: the fixed frame 1-1 has a built-in channel steel bracket 1-1-3 for connecting each support rod, and each support rod has a protruding rubber spring 1-1-1 formed on its top. The other end of the rubber spring 1-1-1 is connected to the vibrating rigid body 1-2. The fixed frame 1-1 serves as the overall support foundation and adopts an integrated design to ensure rigidity and ease of overall hoisting. All non-vibrating components are installed on it.

[0039] Among them, the channel steel bracket 1-1-3 is the main load-bearing structure, and the rubber spring 1-1-1 is installed on the top of the support rod to elastically support the overall vibration-coordinated rigid body 1-2 and achieve vibration isolation.

[0040] Among them, the side of the fixed frame 1-1 is formed with a protruding centrifugal fan support 1-1-4, and the centrifugal fan 1-3 is installed on the centrifugal fan support 1-1-4 by bolts for installing the centrifugal fan 1-3;

[0041] The side of the fixed frame 1-1 is formed with a raised exhaust device support 1-1-2. The angle steel beam 1-4-1 formed on the side of the exhaust device 1-4 is installed on the exhaust device support 1-1-2 by adjusting bolts. The lifting range of the adjusting bolts is ±80mm. The setting of the adjusting bolts can realize the free lifting of the exhaust device 1-4 in vertical height, which facilitates the connection with external pipes and adjusts the exhaust distance.

[0042] To better adapt to different dust removal air pressures, the mesh size of the stainless steel screen plate 1-2-6 can be changed according to the dust removal air pressure, with the mesh size ranging from φ1 to φ5mm. Gas-solid separation is achieved through the screen holes, realizing vibration dust removal.

[0043] To further improve the seismic performance of the cover plate 1-2-7, the cover plate 1-2-7 is bolted to the upper end face of the conveying trough 1-2-3, and a rubber pad is laid on the lower part of the cover plate 1-2-7, which can achieve shock absorption and sealing.

[0044] It should be noted that: the top of the exhaust device 1-4 is provided with a top outlet 1-4-3, which is used to connect to the dust removal pipe of the working environment to realize the guided emission of collected dust gas. A transparent observation window 1-4-2 is installed on the side wall. The observation window 1-4-2 is made of tempered glass, which has impact resistance. Its transparent material allows observation of the internal airflow and dust conditions.

[0045] The upper part of the exhaust device 1-4 is also equipped with a protruding lifting lug 1-4-5, which can be used to install and lift the exhaust device 1-4.

[0046] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
