The embodiment provides a medical sewage pretreatment device, as shown in fig. 1, which comprises a treatment cylinder 4 and a disinfectant liquid storage cylinder 3, wherein the treatment cylinder 4 is connected between a drainage vessel and a drainage pipeline, namely, discharged water passes through the treatment cylinder 4 and then enters the drainage pipeline, a liquid inlet pipe 1 and a liquid mixing funnel 7 are sequentially arranged in the treatment cylinder 4 from top to bottom, a first spiral plate 2 is arranged in the liquid inlet pipe 1 from top to bottom, a second spiral plate 8 is arranged in the liquid mixing funnel 7 from top to bottom, the first spiral plate 2 and the second spiral plate 8 are mainly used for performing spiral guiding function on flowing water, so that the screw pitches of the first spiral plate 2 and the second spiral plate 8 can be relatively arranged to be a larger point, the spiral direction of the first spiral plate 2 is opposite to that of the second spiral plate 8, and in order to enhance the guiding capability of the first spiral plate 2, the liquid inlet pipe 1 can be arranged in a manner that the upper caliber is larger than the lower caliber, the liquid mixing funnel is funnel-shaped mainly for enhancing the flow effect of water flow adherent flow, and the same reason is also provided. The disinfectant liquid storage barrel 3 is annular, the disinfectant liquid storage barrel 3 is sleeved outside the treatment barrel 4, two communicating ports 11 and the disinfectant liquid storage barrel 3 are oppositely arranged on the treatment barrel 4 and communicated with each other, and the communicating ports 11 of the treatment barrel 4 and the disinfectant liquid storage barrel 3 are connected through communicating pipes. The antiseptic solution in the antiseptic solution liquid storage cylinder 3 relies on gravity to flow to the processing section of thick bamboo 4 through communicating pipe certainly, and consequently antiseptic solution liquid storage cylinder 3 sets up should be relatively higher, and the lower limb of the intercommunication mouth 11 in the processing section of thick bamboo 4 is not less than the upper edge of muddy liquid hourglass fill 7, goes out liquid controlling means between feed liquor pipe 1 and the muddy liquid hourglass fill 7, go out liquid controlling means including kickboard 6, shielding plate 10 and the connecting rod 5 that is used for connecting kickboard 6 and shielding plate 10, shielding plate 10 slides and sets up on the intercommunication mouth 11 of processing section of thick bamboo 4, as preferred, intercommunication mouth 11 is provided with two, and shielding plate 10 also correspondingly is provided with two. In order to facilitate the arrangement of the shielding plate 10, the periphery of the communication port 11 is provided with the sliding groove 9, the shielding plate 10 is arranged in the sliding groove 9 in a sliding manner, an adhesive tape is arranged between the sliding groove 9 and the shielding plate 10, the adhesive tape can increase the sealing capacity of the shielding plate 10, the upper end of the sliding groove 9 is provided with an opening, the sliding groove 9 is provided with a limiting element for preventing the shielding plate 10 from sliding out of the sliding groove 9, and the limiting element comprises a limiting table 12 arranged at the bottom of the shielding plate 10 and a limiting column 13 arranged in the upper end of the sliding groove as shown in fig. 2. When the shielding plate 10 is at the lower limit position, the shielding plate 10 completely seals the communication port 11, and the edge of the floating plate 6 is in contact with the funnel surface of the liquid mixing funnel 7, and in order to achieve this state, the end of the second spiral plate 8 should be arranged opposite to the lower side of the floating plate 6 in this state, so as to avoid interference with the floating plate 6. When the shielding plate 10 slides upward from the lower limit position, the area of the communication port 11 shielded by the shielding plate 10 gradually decreases.

In the embodiment, the disinfectant liquid storage cylinder 3 is connected with a disinfectant liquid supplementing pipe, a liquid level control device for controlling disinfectant liquid supplementing is arranged in the disinfectant liquid storage cylinder 3, the liquid level control device can be arranged in the forms of an electronic liquid level sensor and an electric control butterfly valve, when the liquid level is lower than a set liquid level, the electric control butterfly valve is opened to feed liquid, and is closed when the set liquid level is reached; the mechanical liquid level control assembly on the conventional toilet can also be directly applied to the embodiment, and the mechanical liquid level control assembly on the toilet is a known technology and is not described herein.

The working principle is as follows: install this embodiment between drainage household utensils and drainage pipe, when discharging medical sewage, sewage passes through feed liquor pipe 1 and enters into a processing section of thick bamboo 4, and because the guide effect of first spiral plate 2, sewage is the form of rotatory vortex and flows into a processing section of thick bamboo 4, because when not discharging, the medial surface of kickboard 6 and muddy liquid hourglass fill 7 contacts, can avoid liquid to flow through, and when liquid flows down, the fluid can gather in muddy liquid hourglass fill 7, hold up kickboard 6 through buoyancy, kickboard 6 drives shielding plate 10 through connecting rod 5 simultaneously and opens, the antiseptic solution enters into a processing section of thick bamboo 4, in the muddy liquid hourglass fill 7 falls along with sewage, the lower extreme through muddy liquid funnel 7 flows out after the mixture, and finally flows out a processing section of thick bamboo 4. Because the sewage just enters the treatment cylinder 4 in a rotating vortex mode, when the sewage enters the mixed liquid funnel 7, the rotating direction of the vortex can be changed under the action of the second spiral plate, and the sewage and the disinfectant can be fully mixed. After the primary drainage is completed, the shielding plate 10 slides to the lower end of the sliding groove 9 under the action of the self gravity, the gravity of the connecting rod 5 and the gravity of the floating plate 6, and the disinfectant flowing out of the communicating port 11 is blocked.

In the above-mentioned in-process, when the sewage discharge is great in the twinkling of an eye, the sewage water yield is higher at muddy liquid hourglass fill 7 cohesion water level, and the floating plate 6 drags shielding plate 10 and opens the bore increase with the intercommunication mouth, and the liquid measure that the antiseptic solution got into in the treatment section of thick bamboo 4 also can correspondingly increase for reach better neutralization disinfection effect.

In order to reduce the interference of the floating plate 6 on the sewage entering, the upper end of the floating plate can be arranged in a conical surface form, so that the impact effect caused by the falling of water flow is reduced.

Based on the structure of this embodiment, because the existence of liquid mixture funnel 7, this sewage pretreatment device is unsuitable for the operating mode that is used for solid-liquid mixture state, like the sewage treatment of closestool, causes the jam more easily under this kind of condition, and it is better to use the effect under the pure liquid sewage treatment condition.

The above embodiments are only specific cases of the present invention, and the protection scope of the present invention includes but is not limited to the forms and styles of the above embodiments, and any suitable changes or modifications made thereto by those skilled in the art according to the claims of the present invention shall fall within the protection scope of the present invention.
