[0021] 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.

[0022] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 4As shown in this embodiment, a waste liquid cylinder with corrosion resistance includes a base 1 and a cylinder body 2. A mounting cover 3 is provided above the cylinder body 2, and the mounting cover 3 is threadedly connected to the cylinder body 2. The mounting cover 3 has a liquid inlet 27. A locking rod 4 is provided inside the cylinder body 2, and a buffer plate 5 is provided above the locking rod 4. The buffer plate 5 is correspondingly positioned to the liquid inlet 27 and is movably engaged with the mounting cover 3 through the liquid inlet 27. Two sets of symmetrically distributed regulating pipes 13 are provided above the mounting cover 3. A gas collecting tank 15 is fixedly installed above the mounting cover 3. The two sets of regulating pipes 13 are connected to the gas collecting tank 15 through connecting pipes 14. A sliding rod 17 is provided inside the regulating pipe 13, and a piston plate 16 is provided inside the regulating pipe 13. A spring 18 is sleeved on the sliding rod 17, and an regulating plate 19 is sleeved on the sliding rod 17. Both ends are fixedly connected to the adjusting plate 19 and the piston plate 16 respectively. A baffle 11 is fixedly installed inside the cylinder body 2. A filter frame 12 is provided inside the cylinder body 2. The filter frame 12 is threadedly connected to the inner wall of the cylinder body 2 and the baffle 11. The filter frame 12 is slidably sleeved with the clamping rod 4. The cylinder body 2 is made of acid and alkali resistant material. The clamping rod 4 is slidably connected to the cylinder body 2. A sealing ring 10 is fixedly installed at the connection between the cylinder body 2 and the clamping rod 4. A lead screw 6 is provided inside the base 1. A gear 7 is sleeved on the lead screw 6. A rack 8 is provided inside the base 1. A cylinder 9 is provided inside the base 1. The rack 8 is connected to the output end of the piston rod of the cylinder 9. The lead screw 6 is rotatably connected to the base 1 through a bearing. The lead screw 6 passes through the bottom end of the clamping rod 4 and is threadedly connected to the clamping rod 4. The rack 8 is slidably connected to the base 1. The rack 8 is meshed with the gear 7.

[0023] The buffer plate 5, under the action of the lever 4 and the lead screw 6, is adjusted in position within the cylinder 2 to close the inlet 27 and buffer the liquid during inlet, reducing liquid splashing, slowing the rate at which waste liquid is poured into the cylinder 2, and reducing the reaction rate between waste liquids. Simultaneously, when waste gas is generated by the chemical reaction between waste liquids in the cylinder 2, once the gas reaches a certain amount, it will push open the piston plate 16 in the regulating pipe 13 and enter the gas collection tank 15 through the connecting pipe 14, where it will be handled by the staff. This avoids the air pollution caused by the direct release of a large amount of harmful gas into the air from the cylinder 2, and prevents the waste liquid cylinder from accumulating inside the cylinder 2, which could damage the waste liquid cylinder and pose a certain danger. Furthermore, the cylinder 2, sealing ring 10, and base 1 of the waste liquid cylinder are all made of corrosion-resistant materials such as polyvinyl chloride synthetic plastic, ensuring a long service life and good quality.

[0024] like Figure 3 , Figure 5 and Figure 6As shown, piston plate 16 is slidably connected to adjusting tube 13, piston plate 16 is slidably sleeved with slide rod 17, adjusting plate 19 is slidably connected to adjusting tube 13, adjusting tube 13 is provided with two sets of symmetrically distributed screws 20, both sets of screws 20 are sleeved with synchronous pulleys 21, adjusting tube 13 is provided with synchronous belt 22, synchronous belt 22 is respectively connected to the two sets of synchronous pulleys 21, both ends of the two sets of screws 20 pass through adjusting tube 13 and are rotatably connected to adjusting tube 13, both sets of screws 20 pass through both sides of adjusting plate 19 and are threadedly connected to adjusting plate 19, buffer plate 5 is fixedly installed with a locking block 23 below, locking rod 4 is provided with a fixing rod 24, two sets of clamping rods 25 are symmetrically sleeved on the fixing rod 24, locking block 23 is movably locked with the two sets of clamping rods 25, fixing rod 26 is sleeved on the fixing rod 24, both ends of the torsion spring 26 are fixedly connected to the clamping rod 25 and the fixing rod 24 respectively.

[0025] The filter frame 12 filters the solid waste in the waste liquid that enters through the inlet 27 and is buffered by the buffer plate 5. Since the buffer plate 5 and the lever 4 in the waste liquid tank can be movably engaged and disengaged, it is convenient for the staff to remove the buffer plate 5 and the filter frame 12 when cleaning the waste liquid tank, making it easy to clean the solid waste without having to filter and clean the collected waste liquid again. At the same time, the compression of the spring 18 in the regulating pipe 13 in the waste liquid tank can be changed by adjusting the position of the regulating plate 19, which allows the staff to adjust the pressure that the piston plate 16 in the regulating pipe 13 can be pushed up according to the different chemical agents that will be contained in the waste liquid tank.

[0026] This invention provides a waste liquid cylinder with corrosion resistance. The specific working principle is as follows: The position of the buffer plate 5 within the cylinder 2 is adjusted by the action of the lever 4 and the lead screw 6. The cylinder 9 drives the rack 8 to slide, which in turn drives the gear 7 to rotate. The lead screw 6 rotates synchronously with the gear 7, and under the limiting action of the base 1 and the cylinder 2, the lever 4 rises or falls. When the lever 4 drives the buffer plate 5 to rise, it blocks the inlet 27, thus closing the inlet 27. Because the buffer plate 5 has a large diameter, the waste liquid in the cylinder 2 is not easily shaken out. After the lever 4 drives the buffer plate 5 to fall to a certain extent, waste liquid can be poured into the cylinder 2 through the inlet 27. Since the buffer plate 5 is conical, it can buffer the liquid during pouring, reducing splashing, slowing the speed at which the waste liquid is poured into the cylinder 2, and reducing the reaction rate between waste liquids. Simultaneously, when the chemical reaction between the waste liquids in the cylinder 2 produces waste gas... Once the gas reaches a certain amount, it will push open the piston plate 16 in the regulating pipe 13 and enter the gas collection tank 15 through the connecting pipe 14. After unified handling by the staff, it avoids the air pollution caused by the direct discharge of a large amount of harmful gas generated in the cylinder 2 into the air, and the accumulation in the cylinder 2 will cause damage to the waste liquid tank and pose a certain danger. The cylinder 2, sealing ring 10 and base 1 in the waste liquid tank are all made of corrosion-resistant materials such as polyvinyl chloride synthetic plastic, which has a long service life and good quality. The filter frame 12 is set to filter the solid waste in the waste liquid that enters through the liquid inlet 27 and is buffered by the buffer plate 5. Since the buffer plate 5 and the clamping rod 4 in the waste liquid tank can be moved and separated, it is convenient for the staff to remove the buffer plate 5 and the filter frame 12 when cleaning the waste liquid tank, so as to clean the solid waste conveniently without having to filter and clean the collected waste liquid again.
