[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1:

[0024] Please see Figures 1-4 This utility model provides a technical solution: a detachable filter screen frame for hospital sewage treatment, comprising: a frame body 1, with sealing grooves 2 on the front and rear sides of the lower end of the frame body 1, and a coarse filter screen 3 and a fine filter screen 4 respectively disposed in the sealing grooves 2; threaded holes 5 on both sides of the upper end of the frame body 1; and a disassembly and assembly component 6 located on the frame body 1, which is used to press and fix the coarse filter screen 3 and the fine filter screen 4.

[0025] In this implementation scheme, wastewater enters the frame 1 at a flow rate of ≤2m / s. First, it passes through the coarse filter plate 3 (5mm aperture wedge wire structure) to intercept large particles such as cotton swabs and medicine bottle fragments. Then, it passes through the fine filter plate 4 (0.5mm aperture sintered mesh) to trap tiny particles such as cell fragments and colloids. The silicone sealing strip is compressed by 20% under the preload of the 8-10N·m bolt 63 to form a continuous sealing band with a width of 5mm, ensuring that 100% of the wastewater passes through the coarse filter plate 3 and the fine filter plate 4 without bypass leakage.

[0026] Example 2:

[0027] Please see Figures 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: the disassembly assembly 6 includes a pressure plate 61, with through holes 62 on both sides of the upper end of the pressure plate 61, and bolts 63 installed in the through holes 62. The lower end of the bolts 63 is threadedly connected to the inside of the threaded hole 5. Sliding grooves 7 are provided on the front and rear sides of both sides of the inside of the frame 1. The inside of the sliding grooves 7 is slidably connected to the sides of the coarse filter plate 3 and the fine filter plate 4. Positioning holes 8 are provided on the front and rear sides of both sides of the upper end of the frame 1. Positioning pins 9 are inserted into the inside of the positioning holes 8. The upper end of the positioning pins 9 is fixedly connected to the lower end of the pressure plate 61. The frame 1, the positioning pins 9 and the bolts 63 are made of stainless steel. A nitrile rubber sealing gasket is provided at the connection between the inside of the sealing groove 2 and the coarse filter plate 3 and the fine filter plate 4. A silicone sealing strip is provided between the contact surfaces of the pressure plate 61 and the frame 1.

[0028] In this embodiment: During disassembly, loosen the bolt 63, lift the pressure plate 61 upwards, and the positioning post 9 will disengage from the positioning hole 8. Then, the coarse filter plate 3 and the fine filter plate 4 can be pulled out along the slide groove 7. During installation, slide the cleaned or replaced coarse filter plate 3 and fine filter plate 4 into the slide groove 7. Align the pressure plate 61 with the positioning hole 8 through the positioning post 9, and tighten the bolt 63 to complete the fixation.

[0029] The working principle of the detachable filter frame for hospital wastewater treatment provided by this utility model is as follows:

[0030] Implementation steps for the first innovation point:

[0031] Step 1: Wastewater enters frame 1 at a flow rate of ≤2m / s. First, it passes through the coarse filter plate 3 (5mm pore size wedge wire structure) to intercept large particles such as cotton swabs and medicine bottle fragments. Then, it passes through the fine filter plate 4 (0.5mm pore size sintered mesh) to intercept tiny particles such as cell fragments and colloids.

[0032] Step 2: The silicone sealing strip is compressed by 20% under the preload of 8-10 N·m bolt 63 to form a continuous sealing strip with a width of 5 mm, ensuring that sewage passes through the coarse filter plate 3 and the fine filter plate 4 100% without bypass leakage.

[0033] Implementation steps for the second innovation point:

[0034] Step 1: During disassembly, loosen bolt 63, lift pressure plate 61 upwards, and positioning pin 9 will disengage from positioning hole 8. Then, the coarse filter plate 3 and fine filter plate 4 can be pulled out along slide groove 7.

[0035] Step 2: During installation, slide the cleaned or replaced coarse filter plate 3 and fine filter plate 4 into the slide groove 7, align the pressure plate 61 with the positioning hole 8 through the positioning post 9, and tighten the bolt 63 to complete the fixation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
