Description

Technical Field

[0001] The utility model belongs to the field of machinery, and in particular relates to an intelligent auxiliary unloading device for a plate-and-frame filter press. Background Art

[0002] A plate and frame filter press is an intermittent solid-liquid separation device widely used in industries such as environmental protection, coal preparation, metallurgy, food processing, and chemicals. A plate and frame filter press consists of filter plates and a filter frame, forming a filter chamber. A clamping device holds the filter chambers together. A feed pump delivers slurry into each chamber, where it passes through the filter cloth, separating the solid particles from the liquid. The filtrate is discharged along the grooves of adjacent filter plates, while the solid particles are trapped within the filter frame, forming a filter cake. During cake unloading, the filter press's plate puller pulls the filter plates apart one by one, allowing the filter cake to fall off under its own weight. However, due to the strong viscosity of the filter cake and the high pressure of the press, some of the filter cake may adhere to the filter cloth and resist removal. This strong adhesion makes it prone to sticking to the filter cloth. If the filter cake remains firmly attached to the filter cloth for a long time, it will not only cause the filter cloth to deform and sag, but may also affect the filtration efficiency. The filter cake is also weak and easily damaged.

[0003] At present, the filter cake is mainly removed by manual knocking. Due to the short interval between the filter plates, the workers have a short working time, which brings hidden dangers to production safety and easily damages the filter cloth. At present, there are two main auxiliary unloading technology solutions to replace manual work: one is to set a pneumatic vibration device for the filter plate, such as Figure 1 As shown in the figure, this technology adopts a new filter plate structure, which makes each filter plate vibrate up and down by applying external force to make the filter cake fall off; secondly, a mechanical cleaning device for the filter plate is set up, such as Figure 2 As shown, the cleaning device is in direct contact with the filter cake, and the cleaning device moves up and down to cause the filter cake to fall off.

[0004] The two aforementioned technical solutions require vibrating or cleaning each filter plate, which prolongs the filter press's discharge time and reduces its processing capacity per unit time. Furthermore, pneumatic vibrating devices require structural modifications and replacement of new filter plates, which is prohibitively expensive. Mechanical cleaning devices, with their cleaning heads prone to material adhesion, require frequent cleaning. Furthermore, these devices require numerous operating mechanisms, intensive overhaul and maintenance, and high operational costs. A new cleaning device is urgently needed. Utility Model Content

[0005] The purpose of the utility model is to provide an intelligent auxiliary unloading device for a plate and frame filter press to solve the problems in the prior art.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] According to one aspect of the present invention, an intelligent auxiliary unloading device for a plate-and-frame filter press is provided. The filter press includes a filter plate and a plate-pulling trolley. The intelligent auxiliary unloading device for the plate-and-frame filter press includes a track, a traveling trolley, a wind-powered ejector, and an AI camera.

[0008] The track is arranged above the filter press,

[0009] The walking trolley is arranged on the track and can move along the track. The walking trolley moves synchronously with the plate pulling trolley.

[0010] The wind ejector is installed on the traveling trolley and is used to impact the filter cake.

[0011] The AI ​​camera is installed on the traveling trolley, and the AI ​​camera is used to identify the filter cake on the filter plate. When the AI ​​camera identifies that there is filter cake on the filter plate, the wind ejector starts to impact the filter cake.

[0012] Furthermore, an air source pipe for supplying air to the wind-powered ejector is provided on the track.

[0013] Furthermore, brackets are provided at both ends of the track.

[0014] Furthermore, a fill light is installed on the AI ​​camera.

[0015] Furthermore, two AI cameras are installed on the walking cart.

[0017] Furthermore, the wind-powered ejector includes 32 nozzles, and the 32 nozzles are arranged in two rows, corresponding to different areas on both sides of the filter plate.

[0018] Furthermore, the walking trolley moves synchronously with the plate pulling trolley through an infrared positioning device.

[0019] Furthermore, the wind-powered ejector includes a solenoid valve for controlling the opening / closing of the nozzle.

[0020] Furthermore, the intelligent auxiliary unloading device of the plate and frame filter press also includes an intelligent electrical control box. When the AI ​​camera recognizes the filter cake on the filter plate, the intelligent electrical control box receives the recognition information of the AI ​​camera and sends an instruction to the wind ejector. The wind ejector receives the instruction and starts working.

[0021] The utility model has the following advantages: The utility model provides an intelligent auxiliary unloading device for a plate-and-frame filter press, which adopts a method combining visual recognition and pneumatic impact. A track is set above the filter press, a traveling trolley is set on the track, and an AI camera and a high-pressure air jet device are added to the traveling trolley. When the AI ​​camera recognizes that there is filter cake on the filter plate, the pneumatic jet begins to impact the filter cake. This technical solution visually identifies each filter plate and only pneumatically impacts the filter cake that has not fallen off, causing the filter cake to fall off, saving unloading time. The device does not require modification to the original filter press, is simple to operate and maintain, has low cost, and can realize unattended unloading of the filter press.
