[0002] During the wastewater treatment process, waste carbon particles are added to the wastewater. The waste carbon particles can effectively remove organic pollutants and some metal ions in the wastewater through physical adsorption. The addition of waste carbon can improve the efficiency of sewage treatment and help to remove pollutants such as nitrogen and phosphorus.
[0003] The use of waste carbon in wastewater treatment is to fully mix the waste carbon particles with the wastewater so that the waste carbon is in full contact with the pollutants in the water. During this process, the waste carbon adsorbs pollutants such as organic matter and heavy metal ions in the water on its surface. After adsorption treatment, the waste carbon needs to be separated from the wastewater.
[0004] For the transportation of waste carbon into wastewater, the waste carbon particles with a diameter of 1-3 mm are generally selected, and the transportation device is such as Figure 4 As shown, a separate pipe is connected to the wastewater conveying pipe, and a hopper is installed on the upper part of the pipe. Waste carbon particles are placed in the hopper, so that the waste carbon particles enter the wastewater conveying pipe through the pipe under the action of gravity, and then as the wastewater in the wastewater conveying pipe continues to flow, the waste carbon and wastewater are mixed.
[0005] However, this conveying device has defects. Specifically, the waste carbon is discharged at a slow speed, and waste carbon particles in the hopper will remain and cannot be completely mixed with the waste water. Utility Model Content
[0006] The main purpose of the utility model is to provide a waste carbon particle conveying device for sewage treatment, which can make the waste carbon more easily mixed with the wastewater in the water supply pipe, so as to increase the speed at which the waste carbon particles enter the wastewater, and under the action of the wastewater transported by the water injection pipe, the waste carbon particles can all enter the water supply pipe and mix with the wastewater, thereby avoiding the waste carbon particles from remaining in the hopper.
[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0008] A waste carbon particle conveying device for sewage treatment includes a water supply pipe and a hopper. The water supply pipe and the hopper are connected by a feed pipe. The feed pipe includes a first pipe connected to the hopper and a second pipe connected to the water supply pipe. The second pipe is inclined toward the sewage conveying direction of the water supply pipe. The device also includes a water injection pipe. The water outlet of the water injection pipe is located in the hopper.
[0009] Furthermore, a first valve is provided on the feed pipe.
[0010] Furthermore, the inclination angle of the second pipe toward the sewage conveying direction of the water supply pipe is 30 degrees to 60 degrees.
[0011] Furthermore, the hopper includes a conical portion and a straight cylindrical portion, the bottom of the conical portion is connected to the first pipe, and a filtering device is provided in the hopper, and the filtering device is located at the connection between the conical portion and the straight cylindrical portion.
[0012] Furthermore, the filtering device includes a ring body fitted with the straight cylindrical portion, and a filter screen is fixed to the bottom of the ring body.
[0013] Furthermore, a guide surface is provided on the top of the ring body.
[0014] Furthermore, a draw hook is fixed on the top of the filter.
[0015] Furthermore, a second valve is provided on the water injection pipe.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] The water injection pipe of the utility model can transport wastewater into the hopper, so that the waste carbon particles in the hopper can enter the water delivery pipe more quickly through the delivery pipe under the action of the wastewater flow, and the second pipe is inclined toward the sewage delivery direction of the water delivery pipe, so that the waste carbon particles and wastewater in the second pipe can be more easily mixed with the wastewater in the water delivery pipe after entering the water delivery pipe, so as to further increase the speed at which the waste carbon particles enter the wastewater, and under the action of the wastewater transported by the water injection pipe, the waste carbon particles can all enter the water delivery pipe and mix with the wastewater, thereby avoiding the waste carbon particles from remaining in the hopper.
[0018] The filtering device of the utility model can intercept large waste carbon particles in waste carbon particles, thereby preventing the large waste carbon particles from entering the water supply pipe and affecting the purification operation of waste water.
[0019] The top of the ring body of the utility model is provided with a guide surface, which can prevent the ring body and the inner wall of the straight cylinder from forming a step, thereby preventing waste carbon particles from remaining on the top of the ring body.
[0020] The filter screen and the ring body of the utility model form a cavity, and the intercepted large particles of waste carbon will remain in this cavity. Therefore, when personnel remove the filter device from the hopper, the large particles of waste carbon can be taken out of the hopper, making it easy for personnel to clean the large particles of waste carbon in the hopper.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0027] like Figure 1-3 As shown, a waste carbon particle conveying device for sewage treatment includes a water supply pipe 1 and a hopper 4. The water supply pipe 1 and the hopper 4 are connected by a conveying pipe 2. The conveying pipe 2 includes a first pipe 202 connected to the hopper 4 and a second pipe 201 connected to the water supply pipe 1. The second pipe 201 is inclined toward the sewage conveying direction of the water supply pipe 1 and also includes a water injection pipe 5. The water outlet of the water injection pipe 5 is located in the hopper 4.
[0028] In this embodiment, if Figure 1 As shown, the water supply pipe 1 is used to transport wastewater to be treated, and the water injection pipe 5 is connected to the wastewater branch pipe. Therefore, when the wastewater is transported, some of the wastewater will enter the hopper 4 through the water injection pipe 5 and then be collected in the water supply pipe 1 through the feed pipe 2. During this process, personnel can put waste carbon particles into the hopper 4. The waste carbon particles in the hopper 4 are more easily transported into the water supply pipe 1 under the action of the flow of wastewater. In addition, the second pipe 201 is inclined toward the sewage transportation direction of the water supply pipe 1, and the inclination angle is 30 to 60 degrees, so that the waste carbon particles and wastewater in the second pipe 201 can be more easily mixed with the wastewater in the water supply pipe 1 after entering the water supply pipe 1, so as to increase the speed at which the waste carbon particles enter the wastewater.
[0029] Under the action of the waste water transported by the water injection pipe 5 , all the waste carbon particles can enter the water delivery pipe 1 and mix with the waste water, thereby preventing the waste carbon particles from remaining in the hopper 4 .
[0030] Among them, such as Figure 1 and Figure 2As shown, a first valve 3 is provided on the feed pipe 2, and a second valve 7 is provided on the water injection pipe 5. When the waste carbon particles in the hopper 4 need to be fed into the water supply pipe 1, the first valve 3 and the second valve 7 need to be opened. When the waste carbon particles in the hopper 4 do not need to be fed into the water supply pipe 1, the first valve 3 and the second valve 7 are closed. At this time, wastewater cannot enter the hopper 4 through the water injection pipe 5, and the waste carbon particles in the hopper 4 cannot enter the water supply pipe 1 through the feed pipe 2.
[0031] like Figure 2 and Figure 3 As shown, the hopper 4 includes a conical portion 402 and a straight cylindrical portion 401, the large diameter opening of the conical portion 402 is connected and fixed to the straight cylindrical portion 401, and the small diameter opening at the bottom of the conical portion 402 is connected to the first pipe 202. A filtering device 6 is provided in the hopper 4, and an angle is formed at the connection between the conical portion 402 and the straight cylindrical portion 401. The filtering device 6 is positioned by this angle, and the filtering device 6 includes a ring body 602 fitted with the straight cylindrical portion 401, and a filter screen 601 is fixed to the bottom of the ring body 602. When the waste carbon particles are located in the hopper 4, the filter screen 601 can intercept large particles of waste carbon in the waste carbon particles to prevent large particles of waste carbon from entering the water supply pipe 1, and the intercepted large particles of waste carbon will remain in the cavity formed by the filter screen 601 and the ring body 602. Therefore, when personnel remove the filter device 6 from the hopper 4, the large particles of waste carbon can be taken out of the hopper 4.
[0032] Among them, such as Figure 3 As shown, a guide surface 6021 is provided on the top of the ring body 602 , and the guide surface 6021 can prevent the ring body 602 from forming a step with the inner wall of the straight cylinder portion 401 , thereby preventing waste carbon particles from remaining on the top of the ring body 602 .
[0033] Among them, such as Figure 2 As shown, a hook 603 is fixed on the top of the filter screen 601 , and the hook 603 can facilitate personnel to apply an upward force to the filter screen 601 , thereby facilitating personnel to remove the filter device 6 from the hopper 4 .
[0034] Working principle: first, the water supply pipe 1 serves as a wastewater conveying pipe, and the water injection pipe 5 is connected to the wastewater branch pipe. Then, the personnel inject the waste carbon particles into the hopper 4. When the waste carbon particles need to be sent into the water supply pipe 1, the first valve 3 and the second valve 7 are opened. At this time, some wastewater will enter the hopper 4 through the water injection pipe 5 and then be collected in the water supply pipe 1 through the feed pipe 2. In this process, the waste carbon particles in the hopper 4 are more easily transported into the water supply pipe 1 under the action of the wastewater flow, and the second pipe 201 is inclined toward the sewage conveying direction of the water supply pipe 1, and the inclination angle is 30 to 60 degrees, so that the waste carbon particles and wastewater in the second pipe 201 can be more easily mixed with the wastewater in the water supply pipe 1 after entering the water supply pipe 1, so as to increase the discharge speed of the waste carbon particles.
