[0027] Example:

[0028] Please refer to Figures 1 to 5 As shown, this embodiment provides a wastewater treatment device for washing food materials, including: a water inlet device and a purification box. The water inlet device has a filter screen part 11 and a debris removal part 13 which are separately arranged. The filter screen part 11 is provided with filter holes 12 for blocking impurities. The debris removal part 13 is provided with a top block 14 corresponding to the filter holes 12. The filter screen part 11 slides relative to the debris removal part 13 to drive the top block 14 to clear the filter holes 12. The purification box has an inlet and an outlet, and the inlet is connected to the water inlet device. The purification box has a purification bin 21 and a sedimentation bin 22.

[0029] In this embodiment, if Figure 1 and Figure 2 As shown, the water inlet device is a tubular structure, and the filter part 11 is slidably arranged on the impurity removal part 13. When the wastewater passes through the water inlet device, the filter holes 12 on the filter part 11 block the impurities. If the filter holes 12 are blocked, the pressure above the filter part 11 will increase. At this time, the filter part 11 will move along the slide groove 15 toward the direction close to the impurity removal part 13, so that the top block 14 on the impurity removal part 13 will extend into the filter holes 12 when the filter part 11 rotates, so as to clean the filter holes 12, specifically including pushing out the blocked objects and cutting and destroying the filaments, so as to realize the function of automatically clearing the filter holes 12, and the structure is simple and convenient.

[0030] Further, in some implementations of this embodiment, Figure 2 As shown, the impurity removal part 13 is provided with a plurality of limit blocks, the filter part 11 is provided with a slide groove 15 corresponding to the limit blocks, and elastic limit structures are arranged at both ends of the slide groove 15. When the filter part 11 is blocked, the outer pressure becomes larger, driving the filter part 11 to rotate along the slide groove 15 toward the direction close to the impurity removal part 13, and the top block 14 extends into the filter hole 12 to clean the filter hole 12.

[0031] In this embodiment, if Figure 2 As shown, a plurality of limit blocks on the impurity removal part 13 cooperate with the slide groove 15 on the filter part 11 to ensure that the filter part 11 slides within a certain range. The elastic limit structures at both ends of the slide groove 15 are specifically elastic springs or elastic paddles, and the distribution of the slide groove 15 is an arc-shaped distribution groove. The limit block is a general slider fixed on the impurity removal part 13. The limit block abuts against the inner wall of the slide groove 15 and can slide back and forth along the extension direction of the slide groove 15. There is a direct offset angle between the distribution direction of the slide groove 15 and the central axis of the impurity removal part 13. The elastic limit structure can also play a role of buffering and limiting when the filter part 11 slides to a certain position, thereby preventing the filter part 11 from excessive sliding.

[0032] Further, in some implementations of this embodiment, Figure 1 and Figure 2 As shown, it also includes: an auxiliary sleeve 16, a sealing ring 18, and a sealing door 19. The auxiliary sleeve 16 is covered on the water inlet device and communicated with the water inlet device, and a filter screen 17 is arranged at the bottom of the auxiliary sleeve 16; the sealing ring 18 is arranged between the impurity removal part 13 and the filter screen part 11; and the sealing door 19 is rotatably mounted on the auxiliary sleeve 16.

[0033] In this embodiment, if Figure 1 As shown, the auxiliary sleeve 16 is covered outside the water inlet device and is connected to the water inlet device. When the impurity removal part 13 dredges the filter part 11, the pressure pushes the filter part 11 to slide vertically downward, and the water flow will flush the blockage into the auxiliary sleeve 16. The filter 17 at the bottom of the auxiliary sleeve 16 can further filter the impurities in the wastewater to prevent the impurities that cannot be cut from entering the pipe below and causing blockage. The sealing ring 18 is set between the impurity removal part 13 and the filter part 11 to ensure the sealing between the two and prevent wastewater leakage. The sealing door 19 is rotatably installed on the auxiliary sleeve 16 to facilitate the inspection and cleaning of the water inlet device. The auxiliary sleeve 16 and the sealing door 19 are made of transparent materials for easy observation and timely cleaning.

[0034] Further, in some implementations of this embodiment, Figure 3 and Figure 4 As shown, it also includes: a dredging member 23, a solenoid valve, and a plurality of filter plates 24. An output channel is provided at the bottom of the sedimentation bin 22, and the dredging member 23 is rotatably installed at the output channel to assist in the discharge of sediment; the solenoid valve is installed at the output channel to control the output of the sedimentation bin 22; the purification bin 21 has a first channel and a second channel, and the filter plates 24 are divided into two groups and are respectively arranged in the first channel and the second channel.

[0035] In this embodiment, if Figure 4 As shown, a dredging member 23 is rotatably installed at the output channel at the bottom of the sedimentation bin 22. The dredging member 23 is a propeller blade equipped with a control motor. When the sediment in the sedimentation bin 22 needs to be discharged, the dredging member 23 can assist the sediment to be discharged smoothly. The solenoid valve is installed at the output channel to control the output of the sedimentation bin 22, and the output channel can be opened or closed as needed. The purification bin 21 has a first channel and a second channel. The filter plates 24 are divided into two groups and are respectively arranged in the first channel and the second channel. The wastewater is filtered by the filter plates 24 to further remove impurities.

[0036] Further, in some implementations of this embodiment, Figure 4 and Figure 5 As shown, the purification chamber 21 has an inclined side wall, the filter plates 24 are evenly distributed, and there are gaps 25 between the filter plates 24, and the filter plates 24 and the inclined side wall of the purification chamber 21 are parallel to each other.

[0037] In this embodiment, if Figure 5 As shown, the purification chamber 21 has an inclined side wall, and the filter plates 24 are evenly distributed and have a passing gap 25. The filter plates 24 and the inclined side walls of the purification chamber 21 are parallel to each other. This design can increase the contact area between the wastewater and the filter plates 24, improve the filtering effect, slow down the water flow and increase the sedimentation time of the sediment in the entire purification box. The inclined side wall is also conducive to the sedimentation of the sediment, and a plurality of protrusions are provided on the surface of the filter plate 24 to further slow down the flow rate of the water flow, increase the sedimentation and purification time, and thus improve the purification efficiency.

[0038] Further, in some implementations of this embodiment, Figure 2 As shown, the filter screen portion 11 has a conical surface, and the filter holes 12 are evenly spaced and distributed along the circumferential direction of the conical surface.

[0039] In this embodiment, if Figure 2 As shown, the design of the conical surface can increase the filtering area of ​​the filter part 11, improve the filtering efficiency, improve the smoothness of the water flow after the filter part 11 slides downward, and effectively prevent debris from accumulating on the filter part 11. The evenly spaced filter holes 12 can ensure the uniformity of filtering.

[0040] Further, in some implementations of this embodiment, Figure 5 As shown, the gap 25 is provided with flocculants and activated carbon.

[0041] In this embodiment, the flocculant can make the tiny particles in the wastewater condense into larger particles, which are easy to filter and precipitate. The activated carbon can absorb the odor and harmful substances in the wastewater and further purify the wastewater.

[0042] To sum up, in the utility model, through the cooperation between the filter part 11 and the impurity removal part 13 in the water inlet device, when the filter hole 12 is blocked, the pressure on the outer side of the filter part 11 becomes larger, which can drive it to rotate along the slide groove 15 close to the impurity removal part 13, so that the top block 14 extends into the filter hole 12 for automatic cleaning without manual intervention, thereby improving the convenience and working efficiency of the equipment; through graded filtration and impurity removal, as well as the inclined setting of the filter plate 24 and the through gap 25, the sedimentation time and purification area are increased, and the purification effect is improved, and by setting the clearing piece 23, the output of the sedimentation bin 22 is smoother, the structure is simple and convenient, and it is easy to maintain and clean.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
