Description

Technical Field

[0001] This application relates to the technical field of detection device design. Specifically, it relates to a sewage treatment preparation detection device. Background Art

[0002] Sewage treatment: The process of purifying sewage to meet the water quality requirements for discharging into a certain water body or for reuse. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people. When conducting sewage treatment, preparations such as flocculants are needed to precipitate the impurities in the sewage and remove the pigments in the sewage. Before putting these preparations into normal production, a set of devices is required to detect the precipitation and color removal performance of the preparations.

[0003] When the currently common devices for testing preparations mix the preparations and sewage, air is introduced into the mixing cylinder to cause the sewage in the mixing cylinder to surge, thereby accelerating the mixing speed of the preparations and sewage. However, the common testing devices cannot control the air flow rate. The operator can only obtain the mixing data of the preparations and sewage under one air flow rate, and the test samples are relatively single, unable to comprehensively reflect the actual precipitation and color removal efficiency of the preparations.

[0030] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0031] Refer to Figures 1-5 ,

[0032] A sewage treatment preparation detection device includes: a first cylinder 1, a second cylinder 2, an air delivery pipe 3, and a power member 4. Both the upper and lower ends of the first cylinder 1 are open. The second cylinder 2 is a cylinder with both upper and lower ends covered. The second cylinder 2 is located below the first cylinder 1, and the upper end of the second cylinder 2 is fixedly connected to the lower end of the first cylinder 1 by bolts. Both the first cylinder 1 and the second cylinder 2 are made of the same light-transmitting plastic. Six air delivery pipes 3 are provided. The upper ends of the air delivery pipes 3 extend into the first cylinder 1, and the lower ends of the air delivery pipes 3 extend into the second cylinder 2. A number of ventilation holes 5 are formed on the air delivery pipes 3 from top to bottom. The lower ends of the air delivery pipes 3 communicate with the inside of the air delivery pipes 3. The first cylinder 1 is sequentially communicated with the second cylinder 2 through a number of ventilation holes 5 and the inside of the air delivery pipes 3. The second cylinder 2 is externally connected to a gas source. Before adding the preparation and sewage into the first cylinder 1, the gas enters the first cylinder 1 from the second cylinder 2 along the inside of the air delivery pipes 3 and the ventilation holes 5, forming an air flow in the sewage in the first cylinder 1, causing the sewage to roll and flow faster, so as to improve the mixing speed of the sewage and the preparation. Also, because the air pressure at the ventilation holes 5 is greater than the water pressure in the first cylinder 1, it can prevent the sewage from flowing into the second cylinder 2 from the air delivery pipes 3. The power member 4 is arranged in the second cylinder 2 and is used to move the air delivery pipes 3 reciprocally in the longitudinal direction. Since the ventilation holes 5 are arranged longitudinally on the air delivery pipes 3, when the power member 4 moves the air delivery pipes 3 upward, the number of ventilation holes 5 on the air delivery pipes 3 exposed in the first cylinder 1 increases, and the air flow rate flowing into the first cylinder 1 from the air delivery pipes 3 increases, increasing the degree of rolling of the sewage in the first cylinder 1. When the power member 4 moves the air delivery pipes 3 downward, the number of ventilation holes 5 on the air delivery pipes 3 exposed in the first cylinder 1 decreases, and the air flow rate flowing into the first cylinder 1 from the air delivery pipes 3 decreases, reducing the degree of rolling of the sewage, and reducing the degree of rolling of the sewage in the first cylinder 1. To increase the number of test samples of the entire detection device.

[0033] Specifically, the edge of the upper opening of the first cylinder 1 forms serrations. When the air flow rate input into the first cylinder 1 is too large and reaches the critical value of the detection device test, the mixed liquid of the preparation and sewage in the first cylinder 1 will roll and overflow from the upper opening of the first cylinder 1, and the mixed liquid flows through the tooth grooves of the serrations, so that the mixed liquid flows stably.

[0034] Specifically, an annular disk 6 is formed on the outer side of the opening of the first cylinder body 1. The annular disk 6 is used to receive the mixed liquid surging out from the opening at the upper end of the first cylinder body 1, preventing the mixed liquid from spilling onto the ground and causing the operator to slip.

[0035] Specifically, a first pipeline 7 and a second pipeline 8 are connected to the second cylinder body 2. The first pipeline 7 is externally connected to a gas source, the second pipeline 8 is externally connected to the external space, and a valve is provided on the second pipeline 8. The first pipeline 7 and the second pipeline 8 are made of the same light-transmitting plastic as the first cylinder body 1. The first pipeline 7 is used to supply air to the gas transmission pipe 3 through the second cylinder body 2. During the test, if the gas pressure in the second cylinder body 2 is too high, the operator can open the valve on the second pipeline 8 to discharge the excess air in the second cylinder body 2 to reduce the pressure in the second cylinder body 2.

[0036] Specifically, the upper end of the gas transmission pipe 3 forms a hemispherical head 9, and the lower end of the gas transmission pipe 3 forms a disk-shaped flange 10. When the power component 4 moves the gas transmission pipe 3 upward, the gas transmission pipe 3 moves at most until the disk-shaped flange abuts against the upper surface inside the second cylinder body 2. When the power component 4 moves the gas transmission pipe 3 downward, the gas transmission pipe 3 moves at most until the hemispherical head 9 abuts against the upper surface outside the second cylinder body 2. A plurality of ventilation holes 5 are also formed on the hemispherical head, improving the air supply efficiency of the gas transmission pipe 3 to the first cylinder body 1.

[0037] Specifically, the power component 4 includes a cylinder 11 and a support disk 12. The edge of the support disk 12 is attached to the inner wall of the second cylinder body 2 through a rubber pad to form an airtight connection. Three cylinders 11 are provided. The fixed ends of the three cylinders 11 are all fixedly connected to the bottom surface of the inner wall of the second cylinder body 2 through bolts. The output end of the cylinder 11 is fixedly connected to the bottom surface of the support disk 12 through bolts. The cylinder 11 makes the support disk 12 slide reciprocally in the longitudinal direction. The lower end of the gas transmission pipe 3 is fixedly connected to the support disk 12. The support disk 12 divides the inside of the second cylinder body 2 into a first cavity and a second cavity from top to bottom. The first cavity is used to receive the mixed liquid of the preparation and sewage flowing in from the first cylinder body 1 when the seal between the gas transmission pipe 3 and the second cylinder body 2 is not firm. The first pipeline 7 and the second pipeline 8 are both connected to the second cavity. The power component 4 is arranged in the second cavity to avoid being contaminated by the mixed liquid. The support disk 12 forms a number of air guide holes, and all the air guide holes are in one-to-one correspondence and communication with the lower ends of all the gas transmission pipes 3. The air provided by the gas source enters the gas transmission pipe 3 through the first pipeline 7, the second cavity, and the air guide holes in sequence.

[0038] Specifically, waterproof breathable membranes are provided in both the ventilation holes 5 and the air guide holes, further improving the ability to prevent the mixed liquid from flowing into the second cylinder body 2 along the gas transmission pipe 3.

[0039] In another embodiment, a conduit 13 is formed at the upper end inside the second cylinder body 2. The middle part of the air delivery pipe 3 is slidably connected to the conduit 13. The projection of the hemispherical head 9 on the ground and the projection of the disc-shaped convex edge 10 on the ground both surround the projection of the conduit 13 on the ground. The conduit 13 is used to block and seal the vent hole 5 that does not extend into the first cylinder body 1, so as to prevent this part of the vent hole 5 from delivering air into the first cavity and causing an increase in the air pressure in the first cavity, thereby increasing the resistance for the power component 4 to push the support disc 12.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
