Description

Technical Field

[0001] This utility model relates to the technical field of syrup filtration equipment, specifically to a sealed filter with anti-shedding function. Background Technology

[0002] In syrup production, closed filters are commonly used filtration equipment. A closed filter is a device that achieves solid-liquid separation under pressure. Its core principle lies in using pressure to drive liquid through filter plates, trapping solid particles. The filter plates are the key structural components that enable this process.

[0003] Existing closed-loop filters have several issues during operation. When rapid filter switching is required, filter plates can easily detach due to improper operation or excessively rapid pressure changes, impacting production efficiency and potentially posing safety hazards. Therefore, it is necessary to improve existing closed-loop filters to enhance their performance and safety.

[0004] Therefore, this application is submitted. Utility Model Content

[0007] A sealed filter with anti-detachment function includes a tank body with a filter canister and a canister cover. The filter canister is provided with a plurality of vertically evenly arranged filter plates inside. The top of the filter plates is provided with a detachable anti-detachment component for preventing the filter plates from falling off.

[0008] Furthermore, the anti-detachment component includes pressure rods symmetrically located on both sides of the top of the filter plate and a support plate located below the end of the pressure rods. Multiple adjustable-width clamping blocks are sleeved on the outer periphery of the pressure rods, and the clamping blocks limit the top of the filter plate.

[0009] Furthermore, the clamping block includes symmetrical clamping plates and springs located on both sides of the clamping plates.

[0010] Furthermore, the bottom surface of the pressure rod is in contact with the top surface of the filter plate.

[0025] Example 1

[0026] Embodiment 1 of this utility model is a sealed filter with anti-detachment function, including a tank body 1 with a filter tank 2 and a tank cover 3. The filter tank 2 has a plurality of vertically evenly arranged filter plates 20 inside. The top of the filter plates 20 is provided with a detachable anti-detachment component 4 for preventing the filter plates 20 from falling off.

[0027] Reference Figure 1 and Figure 2 This application mainly uses an anti-detachment component 4 installed inside the tank 1, i.e. at the top of the filter tank 2, to limit and fix the top of several filter plates 20 assembled inside the filter tank 2, so as to prevent the filter plates 20 from falling off due to improper operation or excessive pressure when the filter needs to be switched quickly; at the same time, the anti-detachment component 4 adopts a detachable connection, which makes it easy to disassemble and install by opening the tank cover 3.

[0028] Specifically, the anti-detachment component 4 includes pressure rods 40 symmetrically located on both sides of the top of the filter plate 20 and a support plate 41 located below the ends of the pressure rods 40. Multiple adjustable-width clamping blocks 43 are sleeved around the outer periphery of the pressure rods 40, and the clamping blocks 43 limit the top of the filter plate 20. (Refer to...) Figure 2The anti-detachment component 4, which prevents the filter plate 20 from detaching, is mainly achieved through multiple clamping blocks 43 included within it. The clamping blocks 43 primarily clamp and limit the top of the filter plate 20, and the clamping width between the clamping blocks 43 can be adjusted to meet the anti-detachment requirements of filter plates 20 of different specifications. At the same time, the support plate 41 is fixedly connected to the inner wall of the filter tank 2, providing installation conditions for the placement of the pressure rod 40.

[0029] The main limiting function of the clamping block 43 is achieved through the symmetrical clamping plates 44 and springs 45 located on both sides of the clamping plates 44. Specifically, the top of the filter plate 20 is positioned between the two clamping plates 44 and is securely clamped and limited by the springs 45. The initial length of the springs 45 is less than the width of the filter plate 20. During clamping, the springs 45 are stretched to ensure sufficient spacing between them for clamping the filter plate 20, providing a stable clamping effect under elasticity. During clamping, the pressure rods 40 are first placed above the filter plate 20, and then the clamping blocks 43 are placed one by one for limiting. The pressure rods 40 are distributed symmetrically on both sides of the filter plate 20, primarily avoiding the connection between the center of the filter plate 20 and the existing vibration rod, further improving the anti-detachment effect of each filter plate 20.

[0030] Furthermore, the bottom surface of the pressure rod 40 is in contact with the top surface of the filter plate 20. This ensures that the top of the filter plate 20 is not only subjected to the clamping force of the two clamping plates 44, but also to the pressure from the pressure rod 40, thereby firmly limiting the top of the filter plate 20 and improving the anti-detachment effect.

[0031] To achieve a detachable connection of the anti-detachment component 4, a wing screw 42 is also included to connect the support plate 41 and the end of the pressure rod 40. Corresponding threaded holes are provided in the pressure rod 40 and the support plate 41, allowing for easy assembly and disassembly via the wing screw 42, thus achieving a detachable connection. First, the clamping blocks in the pressure rod 40 limit the detachment of each filter plate 20, and then the wing screw 42 is used to limit and fix the entire pressure rod 40.

[0032] In some preferred embodiments, the bottom end of the filter plate 20 is provided with a filter channel 21 communicating with the discharge port 11, and the bottom of the tank body 1 is provided with a feed port 10. Under pressure, the syrup passes through the filter cloth / membrane on the filter plate 20, solid impurities are trapped on the surface of the filter plate 20, and the clarified liquid is discharged through the internal flow channel of the filter plate 20, i.e., the filter channel 21, and the discharge port 11. This is prior art and will not be described in detail here.

[0033] Example 2

[0034] This embodiment 2 is implemented based on embodiment 1, wherein a pressure sensor 5 is provided on the surface of one of the pressure plates, and an avoidance groove 46 through which the pressure sensor 5 passes is provided on the top of the clamping plate 44.

[0035] Specifically, the pressure sensor 5 is electrically connected to an external controller, which is existing technology and will not be described in detail here. It monitors the pressure changes above the filter plate 20 in real time. When the pressure exceeds the preset value, it can issue an alarm in time to remind the operator to make adjustments, thereby enhancing the safety and reliability of the closed filter.

[0036] At the same time, refer to Figure 3 A clearance groove 46 is provided at the top of the clamping plate 44 to prevent the clamping plate 44 from being affected by the assembly of the pressure sensor 5 during its sliding on the pressure rod 40. Furthermore, after being clamped by the spring 45, the position of the clamping plate 44 does not move. It should be noted that the clearance groove 46 is a stepped hole, with the bottom diameter smaller than the upper diameter, providing both clearance and installation functionality.

[0037] In some preferred embodiments, to increase the strength and corrosion resistance of the anti-detachment component 4, the pressure rod 40, support plate 41, and wing screw 42 are made of stainless steel. An anti-stick coating and a corrosion-resistant coating are sequentially applied to the surfaces of the pressure rod 40, support plate 41, and wing screw 42. Using stainless steel and applying anti-stick and corrosion-resistant coatings to their surfaces increases the strength of the pressure rod 40, support plate 41, and wing screw 42, prevents sticking during filtration, facilitates cleaning, and provides corrosion resistance. The anti-stick coating primarily reduces syrup residue and can be a silicone resin coating, which is flexible, resistant to thermal cycling, and low in cost. The corrosion-resistant coating primarily resists acidic components in the syrup and can be an epoxy resin coating.

[0038] The working principle of this utility model is as follows: An anti-detachment component 4, consisting of a support plate 41, a pressure rod 40, a clamping block 43, and a wing screw 42, is installed on the top of the tank 1. The two clamping plates 44 and two springs 45 in the clamping block 43 form a group, which limit and clamp the top of the filter plate 20, thereby clamping the top of the filter plate 20 and effectively preventing the filter plate 20 from falling off when the pressure changes drastically, thus improving the performance and safety of the equipment. At the same time, the pressure sensor 5 monitors the pressure change above the filter plate 20 in real time. When the pressure exceeds the preset value, it can issue an alarm in time to remind the operator to make adjustments, thereby enhancing the safety and reliability of the sealed filter.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
