Description

Technical Field

[0001] This utility model belongs to the technical field of material screening equipment, and specifically relates to a discharge device for an ultrasonic vibrating screen. Background Technology

[0002] In the application of ultrasonic vibrating screens, the performance of the discharge device directly affects the overall screening efficiency and equipment maintenance costs. Currently, traditional ultrasonic vibrating screen discharge devices mostly adopt a single discharge port design. During the material screening process, when the throughput is large, the material discharge speed is slow, and it is easy to accumulate on the receiving panel. This not only affects the continuity of screening but may also lead to a decrease in screening accuracy due to material retention, thereby reducing the overall screening efficiency. The connection structure between the discharge nozzle and related components of existing discharge devices is relatively complex, often using welding or multiple sets of bolts for fixing. This connection method makes the disassembly and installation process cumbersome when the discharge nozzle needs maintenance or cleaning, requiring a lot of manpower and time. This not only increases the difficulty of equipment maintenance but also prolongs downtime, increasing maintenance and time costs in the production process, making it difficult to meet the needs of efficient and convenient production. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a discharge device for an ultrasonic vibrating screen, which improves discharge efficiency and ease of equipment installation.

[0004] This utility model is achieved through the following technical solution:

[0005] An ultrasonic vibrating screen discharge device includes a material box, a discharge pipe, a discharge nozzle, a screener, an ultrasonic generator, and support legs.

[0006] The material box is equipped with support legs around its bottom, is hollow inside, has a feed pipe at the top, and a conical groove at the bottom; the bottom of the conical groove is connected to the discharge nozzle through a discharge pipe, the discharge nozzle is inverted conical and is connected to the top of the screener; a first valve is connected to the body of the discharge pipe.

[0007] The screener is hollow inside and has discharge ports at both ends that penetrate its main body; ultrasonic generators are provided on both sides of the screener; and a screen is provided inside the screener above the discharge port.

[0008] The working principle of this utility model is as follows:

[0009] Close the first valve and then feed the material to be screened into the hopper through the feed pipe. The conical groove at the bottom of the hopper ensures that the material flows out smoothly on the inclined surface. After screening begins, the operator opens the first valve and turns on the ultrasonic power supply. The material enters the screener through the discharge pipe, and after being screened on the screen, the fine material falls below the screen and flows out through the discharge port. The discharge port runs through the entire screener, forming two outlets on both sides, ensuring the material flow rate and preventing blockages, thereby improving screening efficiency.

[0010] As a further improvement of this utility model, the top of the screener is provided with a fixing block, and the periphery of the discharge nozzle is provided with a fixing ring, the fixing ring having a notch that matches the fixing block; the main body of the fixing block is provided with a threaded hole for placing a fixing nut.

[0011] The discharge nozzle can be quickly positioned and installed on top of the screen by using a fixing block and a fixing ring for positioning and installation. Finally, the fixing ring can be fixed with a nut, which is convenient for disassembly and installation.

[0012] As a further improvement of this utility model, a second valve is connected to the feed pipe body.

[0013] The feed pipe can be connected to an external storage tank and then continuously convey materials mechanically. A second valve is installed to facilitate control of the speed at which materials enter the hopper.

[0014] As a further improvement of this utility model, the bottom of the support leg is provided with a rubber pad.

[0015] Rubber pads can prevent the entire device from vibrating significantly during the screening process.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model improves the material outflow by opening the discharge port, avoiding material accumulation and blockage after screening, thereby improving screening efficiency.

[0018] 2. This utility model uses a fixing block and a fixing ring to position and install the discharge nozzle, enabling quick installation of the discharge nozzle and the screener, and facilitating equipment assembly. Attached Figure Description
