Description

Technical Field

[0001] The invention relates to the technical field of porous medium filter plate cleaning, in particular to a porous medium filter plate for adding an ultrasonic vibrator. Background Art

[0002] Porous media filter plates are a type of filter material with numerous tiny pores, which are widely used in solid-liquid separation, gas-liquid separation and other processes in various fields. Common materials include porous ceramics, metal powder sintered materials, and polymers. Among them, porous ceramic filter plates are made of corundum, silicon carbide, etc. through special processes; metal powder sintered filter plates, such as titanium sintered plates, are made of high-quality spherical high-purity metal powders through forming and high-temperature sintering; polymer filter plates are made of materials such as polypropylene and polytetrafluoroethylene, and are filled with criss-crossing, interconnected capillary pores with different pore sizes, ranging from a few nanometers to tens of microns. These micropores provide channels for fluids to pass through, and at the same time can intercept particulate matter to achieve the purpose of filtration and separation.

[0003] In current industrial production and various filtration application scenarios, existing porous media filter plates generally have a significant limitation. Most of these filter plates are not equipped with a functional structure on the surface that is convenient for installing ultrasonic vibrators in terms of design and construction. This design deficiency has caused a series of thorny problems in actual use. When the porous media filter plate is put into operation alone, especially when dealing with liquids or suspensions containing a large amount of sludge, the situation is not optimistic. The fine particles in the sludge will continue to impact the filter plate with the fluid, gradually penetrate into and adhere to the inside of the filter holes;

[0004] As time goes by, the amount of sludge attached continues to increase, eventually causing the filter holes to be seriously blocked. Once the filter holes are blocked, the filtration efficiency of the porous medium filter plate will drop significantly. The filter plate that was originally able to efficiently separate solids and liquids can no longer allow liquids to pass smoothly, slowing down the entire filtration process and greatly reducing production efficiency. In order to maintain normal production, the staff has to frequently clean and maintain the filter plates, which not only consumes a lot of manpower, material resources and time costs, but may also cause production interruptions due to downtime for cleaning, causing economic losses to the company.

[0005] Moreover, frequent clogging and cleaning of the filter plate will accelerate the wear of the filter plate, shorten its service life, and further increase the company's operating costs. Therefore, the lack of an ultrasonic vibrator function installed on the surface makes it difficult for the porous medium filter plate to perform at its best when facing silt and other easily clogged materials, greatly reducing the use effect of the porous medium filter plate. Summary of the invention

[0006] The object of the present invention is to provide a porous medium filter plate for adding an ultrasonic vibrator to solve the problems raised in the above background technology.

When the sliding plate is sliding, the telescopic rod is constantly in a state of compression and tension, thereby ensuring the stability of the sliding plate during the sliding process.

[0013] Preferably, a spring is sleeved on the surface of the fixed rod, and the spring is arranged between the sliding plate and the mounting block. Based on the elastic potential energy stored in the spring, the sliding plates on both sides can be driven to slide along the surface of the fixed rod in directions away from each other, thereby driving the clamping rods on both sides to move synchronously in directions away from each other.

On the one hand, the migration speed of bubbles in the pores of the filter plate is improved, and the segmentation of dust-containing bubbles is accelerated. On the other hand, the mechanical vibration can effectively remove the dust adhered to the inner surface of the filter plate aperture.

[0020] 2. The porous medium filter plate used for adding an ultrasonic vibrator head can drive the sliding plates on both sides to slide along the surface of the fixing rod in directions away from each other based on the elastic potential energy stored in the spring through the set fixing mechanism, thereby driving the clamping rods on both sides to move synchronously in directions away from each other, so that they are clamped into their respective corresponding slots, thereby realizing precise positioning of the porous medium filter plate body.

A groove is provided in the pulling plate 26. The setting of the pulling plate 26 facilitates pulling the sliding plate 23.

[0034] Furthermore, there are two clamping rods 22, which are symmetrically arranged. The clamping rods 22 move synchronously in directions away from each other so that they are clamped into their respective corresponding slots, thereby achieving precise positioning of the porous medium filter plate body 1.

[0036] Embodiment 2:

[0037] See also Figure 5, and on the basis of Example 1, the fixing mechanism 3 is further obtained to include a placement block 31, the placement blocks 31 are fixedly connected to the front and rear sides of the support plate 204, a limiting groove is provided in the placement block 31, a mounting rod 34 is inserted in the limiting groove, the mounting rod 34 is fixedly connected to the bottom of the porous medium filter plate body, the limiting plate 33 is just inserted into the mounting groove provided inside the placement block 31, and the mounting rod 34 is also synchronously inserted into the placement block 31, on this basis, the locking nut 32 is screwed to the surface of the mounting rod 34 in a threaded connection manner, and the limiting rod 205 is firmly fixed in this way, providing convenient conditions for the subsequent installation and fixation of the ultrasonic vibrator body 4.

Then, the support plate 204 is placed at the bottom of the porous medium filter plate body 1. When the limiting rod 205 on the top of the support plate 204 is accurately inserted into the preset filter hole inside the porous medium filter plate body 1, the pull plate 26 is released. At this time, based on the elastic potential energy stored in the spring 29, the sliding plates 23 on both sides can be driven to slide along the surface of the fixing rod 28 in directions away from each other, thereby driving the clamping rods 22 on both sides to move synchronously in directions away from each other, so that they are clamped into their respective corresponding clamping grooves, thereby achieving accurate positioning of the porous medium filter plate body 1. At the same time, the limiting plate 33 is just inserted into the installation groove opened inside the placement block 31, and the installation rod 34 is also inserted into the placement block 31 synchronously. On this basis, the locking nut 32 is screwed to the surface of the installation rod 34 in a threaded connection manner. In this way, the limiting rod 205 is firmly fixed, providing convenient conditions for the subsequent installation and fixation of the ultrasonic vibrator body 4;

[0040] Under the action of the ultrasonic vibrator body 4, ultrasonic mechanical vibration is used to drive the filter plate to vibrate up and down with high frequency and micro amplitude. On the one hand, the migration speed of bubbles in the pores of the filter plate is improved, and the segmentation of dust bubbles is accelerated. On the other hand, mechanical vibration can effectively remove dust adhered to the inner surface of the filter plate aperture. At the same time, the filter plate continuously vibrates with high frequency and micro amplitude, and it is difficult for silt to adhere to the filter plate, so that the filter plate can maintain high permeability during long-term operation, realize long-term automatic operation of the system, and reduce the subsequent maintenance investment and replacement of consumables.
