[0029] Embodiment 1

[0030] The present embodiment 1 provides a sewage treatment device for blocking and discharging residue, as shown in the specific structure as follows. Figures 1-2

[0031] Please refer to Figure 1 The sewage treatment device for blocking and discharging residue of the present embodiment mainly consists of four parts: a sewage collection tank 1, a residue blocking cylinder 2, a residue discharging pipe 3 and a residue discharging valve 5. The sewage collection tank 1 is a rectangular pool formed by cement pouring, which is used for temporarily storing filtered sewage.

[0032] Further, the residue blocking cylinder 2 is vertically installed in the sewage collection tank 1. The main material of the residue blocking cylinder 2 is stainless steel, which has the advantages of high strength, firmness, durability and corrosion resistance. With the increase of service life, it is also beneficial to the later operation and maintenance. In combination with Figure 1 and Figure 2 As shown in the drawings, the residue blocking cylinder 2 is a cylindrical structure. A plurality of evenly distributed interception holes 201 are formed in the side wall of the residue blocking cylinder 2. According to the size of the impurities to be intercepted, the aperture of the interception hole 201 can be set to 1.5mm-40mm, preferably 20mm. The residue blocking cylinder 2 has a cavity for accommodating impurities. The impurities with a size larger than the aperture of the interception hole 201 are intercepted in the cavity of the residue blocking cylinder 2, which is convenient for unified discharge.

[0033] Further, the residue discharging pipe 3 is used for discharging the intercepted impurities. The residue discharging pipe 3 includes an inner pipe 301, a connecting pipe 302 and an outer pipe 303 connected in sequence from top to bottom. The inner pipe 301 and the outer pipe 303 are both in vertical state, and the inner pipe 301 is located inside the sewage collection tank 1, and the outer pipe 303 is located outside the sewage collection tank 1. The connecting pipe 302 passes through the side wall of the sewage collection tank 1 from high right to low left. The top of the inner pipe 301 has a flange, which is connected with the lower end flange 202 of the residue blocking cylinder 2. A sealing ring is installed at the connection to prevent leakage. The top of the residue blocking cylinder 2 is provided with an upper end flange 203, which is connected with the flange of the water inlet pipe 4. A sealing ring is also installed at the connection to prevent leakage.​

[0034] It should be noted that, as shown in Figure 1 The inner tube 301, the connecting tube 302 and the outer tube 303 are all straight tubes, and the upstream end of each tube is higher than the downstream end, so that the sundries can slide from top to bottom in the slag discharge pipe 3 during slag discharge, preventing blockage.

[0035] In some embodiments of the present embodiment, as shown in Figure 1 Two supports 8 are installed on the outer wall of the sedimentation tank 1, and the supports 8 are fixedly connected with the outer tube 303, and the supports 8 support the outer tube 303.

[0036] As shown in Figure 1 In the present embodiment, the slag discharge valve 5 is an electric valve, and the slag discharge valve 5 and the timing controller are electrically connected through wires. The timing controller is a PLC control in the prior art, which controls the slag discharge valve 5 to open once every certain time, and each opening lasts for 30 seconds. Manual opening is not required, further saving manpower.

[0037] The diameter D of the slag blocking cylinder 2 can be calculated according to the following formula to match the sewage flow and the size of the retention hole 201,

[0038]

[0039] In the above formula: D—diameter of the slag blocking cylinder 2 (mm);

[0040] Q—flow rate (m 3 / s);

[0041] V—perforation flow rate (m / s), generally 0.3-1.0 m / s;

[0042] H—height of the annular curved surface of the slag blocking cylinder 2 (m);

[0043] a—open hole rate of the annular curved surface of the slag blocking cylinder 2;

[0044] b—clogging rate of the slag blocking cylinder 2.

[0045] For example, when the water inflow Q is 500 m 3 / d (0.0058 m 3 / s), the perforation flow rate v is 0.3 m / s, the height H of the annular curved surface of the slag blocking cylinder 2 is 1 m, the open hole rate a of the annular curved surface of the slag blocking cylinder 2 is 20%, and the clogging rate b of the slag blocking cylinder 2 is 60%, the appropriate diameter D of the cylindrical slag blocking device is calculated to be 154 mm. It should be noted that the clogging rate of the slag blocking cylinder 2 refers to the accumulation and blockage of the retention hole 201 during interception, and the clogging rate refers to the percentage of the blocked holes to the total hole area.

[0046] Example 2

[0047] The embodiment is based on the embodiment 1, and further comprises a slag collecting bucket 6 and a water tank 7,

[0048] Please refer to Figure 1 As shown in the figure, the slag collecting bucket 6 is installed outside the silt collecting pool 1, and the top of the slag collecting bucket 6 is vertically aligned with the outlet of the slag discharging pipe 3, so as to receive the sundries discharged by the slag discharging pipe 3.

[0049] The slag discharging pipe 3 is installed below the water tank 7, and the bottom of the slag discharging pipe 3 is provided with a plurality of water leakage holes which are aligned with the water tank 7 below. The water leakage holes have the same diameter as the trapping holes 201. The bottom of the slag collecting bucket 6 and the bottom of the water tank 7 have a certain gap, and the water tank 7 is installed with a sewage discharge pipe 701 which is communicated with the gap between the bottom of the slag collecting bucket 6 and the bottom of the water tank 7. The sewage in the water tank 7 can be discharged through the sewage discharge pipe 701.

[0050] Since a part of the sewage is also discharged out of the silt collecting pool 1 together with the sundries, the sundries discharged out of the silt collecting pool 1 are stored in the slag collecting bucket 6 through the water leakage holes in the bottom of the slag collecting bucket 6, and a part of the sewage discharged out of the silt collecting pool 1 flows out through the water leakage holes and then enters the subsequent sewage treatment equipment through the sewage discharge pipe 701.

[0051] Embodiment 3

[0052] The embodiment is based on the silt collecting and discharging device for treating sewage in the embodiment 1, and two series-connected silt collecting barrels 2 are connected between the water inlet pipe 4 and the slag discharging pipe 3. A three-way valve is connected to the end of the water inlet pipe 4, and the two outlets of the three-way valve are respectively connected to the inlet ends of the two silt collecting barrels 2. Similarly, a three-way valve is also connected to the top end of the slag discharging pipe 3, and the two inlets of the three-way valve are respectively connected to the outlet ends of the two silt collecting barrels 2. Both of the three-way valves are electrically controlled three-way valves in the prior art. Under the control of the two electrically controlled three-way valves, the inlet end of one of the silt collecting barrels 2 is kept closed and the outlet end is kept open, so that the silt collecting barrel 2 functions as a slag discharging barrel, and the inlet end of the other silt collecting barrel 2 is kept open and the outlet end is kept closed, so that the silt collecting barrel 2 functions as a filtering barrel. When the slag discharging barrel 2 is discharged and the filtering barrel 2 contains a proper amount of sundries, the two electrically controlled three-way valves are reversely controlled, so that the slag discharging barrel 2 starts the filtering operation and the silt collecting barrel 2 containing the sundries starts the slag discharging operation.

[0053] By connecting the two silt collecting barrels 2 in parallel, one of the silt collecting barrels 2 can always function as a filtering barrel, and the water inlet pipe 4 does not need to be closed, so that the use effect is better.

[0054] The working principle of the utility model is as follows:

[0055] The sewage treatment blocking and discharging device controlled by the discharging valve 5 plays a role of blocking or discharging. When the discharging valve 5 is closed, sewage flows into the blocking cylinder 2 from the water inlet pipe 4, and the sundries are blocked and cannot pass through the interception hole 201 of the blocking cylinder 2, while the sewage can pass through the interception hole 201 and enter the sewage collecting tank 1, so that the blocking cylinder 2 plays a physical filtering role of separating the sundries and the sewage. When the discharging valve 5 is opened, the sewage in the sewage collecting tank 1 passes through the interception hole 201 and enters the blocking cylinder 2, and the sewage mixed with the intercepted sundries enters the discharging pipe 3 and is finally discharged from the outlet end of the discharging pipe 3, so that the automatic discharging is realized. The reverse flow of the sewage can flush the blocking cylinder 2 and help the sundries to be discharged. Under the gravity and the flushing of the sewage, the sundries automatically enter the discharging pipe 3 and automatically fall along the discharging pipe 3, so that the labor intensity is reduced and the labor is saved. The sewage treatment blocking and discharging device controlled by the discharging valve 5 plays a role of blocking or discharging. The discharging valve 5 can be an electric valve or a manual valve, and the opening and closing can be realized by electric control or manual operation. Compared with the prior art, whether the manual operation or the electric control has a lower operation and maintenance cost, and is suitable for popularization and use.
