Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a microbial nutrient agent delivery device. Background Art

[0002] Microbial wastewater treatment utilizes the metabolic activity of microorganisms to degrade and remove pollutants such as organic matter, nitrogen, and phosphorus from wastewater. This method primarily relies on natural or cultivated microbial communities, typically including bacteria, fungi, and protozoa. Advantages of microbial wastewater treatment include high treatment efficiency, relatively low investment and operating costs, and minimal environmental impact. Typically, activated sludge—a large microbial community—is cultivated within wastewater treatment facilities to degrade pollutants.

[0003] The sewage in many cities in my country generally has the characteristics of low organic matter and high phosphorus. This makes it impossible for conventional denitrification and phosphorus removal processes to meet the demand for carbon sources in the anoxic denitrification stage. The lack of sufficient carbon sources hinders the denitrification process and limits the denitrification effect. At the same time, the obstruction of the denitrification process inhibits the proliferation of anaerobic and aerobic bacteria, further affecting the denitrification effect of the sewage treatment plant. In order to meet the requirements for total nitrogen in the effluent, it is often necessary to add an external carbon source to promote denitrification. In the existing technology, the feed is directly added through a sprinkling device. This feeding device has the advantage of fast feeding speed, but it also has the problem of raw material waste.

[0004] Patent publication number CN220926439U discloses a biochemical pool nutrient dosing device, which includes a carbon source box, a rotating plate at the inlet below the carbon source box, a through slot adapted for the inlet, and a baffle hinged to the bottom of the through slot. The baffle is designed to control the delivery of the carbon source. This delivery device can only deliver the carbon source at a fixed point, resulting in uneven delivery. Multiple carbon source deliveries are required, which is time-consuming and labor-intensive. Furthermore, due to the uneven delivery, the carbon source is wasted. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example:

[0031] A microbial nutrient delivery device, such as Figure 1 As shown, it includes a base 1, a blowing structure and a blanking structure, and the blowing structure and the blanking structure are all arranged on the base 1; Figure 2 As shown, the blowing structure includes a blower 10 and a discharge barrel 2, and the unloading structure includes a storage hopper 5, a support plate 7, a sealing plate 12, a control motor 17, an eccentric wheel 16, and a rocker 15; the blower 10 is arranged on the base 1, the discharge barrel 2 is arranged at the air outlet of the blower 10, and a receiving barrel 3 is arranged on the top of the discharge barrel 2. The storage hopper 5 is fixedly connected to the base 1 through the support plate 7, and the bottom of the storage hopper 5 faces the receiving barrel 3. A support frame 9 is provided on the base 1, and the sealing plate 12 is movably connected to the support frame 9. One side of the sealing plate 12 is located at the bottom of the storage hopper 5. The control motor 17 is fixedly connected to the support frame 9, and the eccentric wheel 16 is fixedly connected to the output shaft of the control motor 17. Figure 5 as well as Figure 6 As shown, the two ends of the rocker 15 are hinged to the sealing plate 12 and the eccentric wheel 16 respectively. Among them, the storage hopper 5 is used to store the material to be added, such as the carbon source. The sealing plate 12 can block the bottom of the storage hopper 5. The control motor 17 is used to drive the eccentric wheel 16 to rotate. The eccentric wheel 16 is used to drive the rocker 15 to swing. The rocker 15 is used to pull the sealing plate 12 to move back and forth. After the sealing plate 12 moves, the bottom of the storage hopper 5 can be opened. After the bottom of the storage hopper 5 is opened, the material in the storage hopper 5 can enter the receiving barrel 3 and further enter the discharge barrel 2. The blower 10 is used to blow air and carry the material in the discharge barrel 2 out to achieve uniform feeding. The blower 10 and the control motor 17 are both powered by the battery 11. The battery 11 is set on the base 1. The provision of the battery 11 can improve the flexibility of use.

[0032] Specifically, when in use, materials are put into the storage hopper 5, such as small dough. Then, the control motor 17 and the blower 10 are started at the same time, and the rotation speed of the control motor 17 is adjusted first to ensure that the sealing plate 12 can move relatively smoothly. During the reciprocating motion of the sealing plate 12, the bottom of the storage hopper 5 will be intermittently opened. When the bottom of the storage hopper 5 is opened, part of the material in the storage hopper 5 will fall down, and the fallen material will enter the discharge barrel 2 after passing through the receiving barrel 3. The wind blown by the blower 10 will blow out the material in the discharge barrel 2 to complete the feeding. It should be noted here that due to the design of the sealing plate 12, the storage hopper 5 is intermittently unloaded. Therefore, the air outlet speed of the blower 10 can be controlled so that the air outlet speed of the blower 10 matches the unloading frequency of the storage hopper 5 to change, thereby achieving feeding at different distances, which can further ensure the uniform delivery of materials.

[0033] In a preferred embodiment, Figure 2As shown, the storage hopper 5 has a large top opening and a small bottom opening. A cover plate 6 is hingedly connected to the top of the storage hopper 5. The large top opening allows users to quickly and easily drop various materials, such as carbon sources, into the storage hopper 5, thereby improving operational efficiency and convenience. Furthermore, the small bottom opening effectively controls the material discharge rate, preventing excessive material from falling all at once. The hinged top cover plate 6 protects the material within the storage hopper 5.

[0034] In a preferred embodiment, Figure 4 As shown, the discharge barrel 2 is tilted on the base 1, and the outlet of the discharge barrel 2 is tilted upward. The tilted setting of the discharge barrel 2 can utilize the effect of gravity to make the material in the storage hopper 5 flow into the discharge barrel 2 more smoothly after passing through the receiving barrel 3. This design reduces the retention of materials during the discharging process and reduces the risk of material blockage, thereby ensuring that the material can be continuously and stably transported to the outlet. The upward tilt of the outlet of the discharge barrel 2 also helps the injection and diffusion of the material. The airflow blown by the blower 10 can more effectively carry the material upward and form a uniform and rapid feeding effect. Such a design not only improves the accuracy of feeding, but also improves the overall working efficiency of the system.

[0035] In a preferred embodiment, Figure 4 As shown, a connecting pipe 21 is connected to one side of the discharge barrel 2, and the discharge barrel 2 is connected to the air outlet of the blower 10 through the connecting pipe 21. The separate setting of the connecting pipe 21 can facilitate the connection between the discharge barrel 2 and the blower 10. In addition, the connecting pipe 21 can also be set to a detachable connection design to facilitate the replacement of the blower 10.

[0036] In a preferred embodiment, Figure 4 As shown, a fixed frame 8 is fixed to the support frame 9, and the fixed frame 8 is arranged horizontally. Sliding side plates 13 are fixed to the bottom of both sides of the fixed frame 8, and the sealing plate 12 is slidably connected to the sliding side plates 13. The design of the fixed frame 8 and the sliding side plates 13 is to ensure the smooth sliding of the sealing plate 12. Specifically, the horizontal arrangement of the fixed frame 8 provides a stable support structure for the equipment, ensuring that the sealing plate 12 can move smoothly along the predetermined trajectory during the material unloading process. The setting of the sliding side plates 13 provides a guide for the sealing plate 12, so that the sealing plate 12 maintains linear motion during the opening and closing process, thereby avoiding unstable operation or jamming caused by irregular motion trajectory.

[0037] In a preferred embodiment, Figure 2As shown, a lower hopper 4 is fixed to one side of the fixed frame 8, with one end of the lower hopper 4 facing the bottom of the storage hopper 5 and the other end facing the receiving barrel 3. The design of the lower hopper 4 can facilitate the material in the storage hopper 5 to enter the receiving barrel 3. Specifically, the design of the lower hopper 4 takes into account the smoothness and stability of the material flow. On the one hand, the design facing the bottom of the storage hopper 5 enables the lower hopper 4 to fit tightly with the storage hopper 5, thereby avoiding material retention or blockage during the transfer process. On the other hand, the structure facing the receiving barrel 3 allows the material to fall quickly by gravity, and uses natural fluidity to enable the material to flow quickly and evenly into the receiving barrel 3, ensuring efficient material discharge.

[0038] In a preferred embodiment, Figure 2 As shown, a fixing plate 20 is fixed to one side of the fixing frame 8 near the top, and the control motor 17 is detachably connected to the fixing plate 20. A connecting seat 14 is fixed to the bottom of the sealing plate 12, and the two ends of the rocker 15 are hinged to the connecting seat 14 and the eccentric wheel 16 respectively. The design of the fixing plate 20 facilitates the installation of the control motor 17, and the design of the connecting seat 14 facilitates the rotational connection between the remote sensing and the sealing plate 12, and prevents interference between the rocker 15 and the sealing plate 12. Specifically, the design of the fixing plate 20 provides a stable foundation on which the control motor 17 can be firmly installed. The design of the connecting seat 14 ensures that the rocker 15 can smoothly drive the sealing plate 12 to move left and right. By hingedly connecting the rocker 15 to the connecting seat 14 and the eccentric wheel 16, precise control of the sealing plate 12 can be effectively achieved. At the same time, the reasonable position and shape design of the connecting seat 14 avoid interference between the rocker 15 and the sealing plate 12, ensuring that the smoothness of operation will not be affected by conflicts between components when the sealing plate 12 is opened and closed.

[0039] In a preferred embodiment, Figure 2 As shown, a connecting rod 19 is fixed to one side of the top of the fixing frame 8. The end of the connecting rod 19 is fixed to the mounting plate 18. A compression spring 22 is provided between the mounting plate 18 and the sealing plate 12. The ends of the compression spring 22 are respectively fixed to the sealing plate 12 and the mounting plate 18. After the control motor 17 is turned off, the compression spring 22 resets and pushes the sealing plate 12 to move, keeping the sealing plate 12 sealed to the bottom of the storage hopper 5. Further optimized, a flange 23 is provided on one side of the sealing plate 12, and the sealing plate 12 is connected to the compression spring 22 via the flange 23. The design of the flange 23 on the sealing plate 12 facilitates the connection with the compression spring 22.

[0040] In a preferred embodiment, the base 1 and the support frame 9 are both made of hollow square tubes. The base 1 and the support frame 9 made of hollow square tubes can effectively reduce the overall weight of the device.
