[0038] The core of this application is to disclose a dosing device to reduce dust spillage during the dosing process.
[0039] Another key aspect of this application is the disclosure of a wastewater treatment system that includes the aforementioned dosing device.
[0040] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.
[0041] In wastewater treatment, solid chemicals such as defluorinating agents, calcium hydroxide, aluminum sulfate, sodium bicarbonate, and calcium oxide are required for treatment. These chemicals are typically transported in ton bags. Existing dosing devices use a conical unpacker to cut a small opening at the bottom of the ton bag and then use a mechanical mechanism to lift the bag, allowing the chemicals to flow into the dosing device and then into the wastewater tank or chemical mixing tank. However, this dosing device can only cut a small opening at the center of the bottom of the ton bag, while chemicals located at the edges cannot flow out smoothly. Repeated manual cutting of the ton bag is required to ensure complete drainage, resulting in low dosing efficiency. Furthermore, the process of lifting the ton bag and manual cutting generates a large amount of chemical dust, which can diffuse through the gap between the ton bag and the dosing device, causing harm to human health and polluting the environment. Therefore, this application discloses a dosing device and a wastewater treatment device.
[0042] Combination Figures 1-7 The dosing device disclosed in this application includes a dosing chamber 100, a disassembly assembly, and a water film dustproof assembly. The dosing chamber 100 includes a dosing area 110 and a dust removal pipe installation area 120. The dosing area 110 is located at the bottom of the dust removal pipe installation area 120 and communicates with it. A dosing outlet 102 is provided at the bottom of the dosing area 110, and a dosing inlet 101 is provided at the top of the dust removal pipe installation area 120. The disassembly assembly is located inside the dosing area 110. When a medicine bag passes through the dust removal pipe installation area 120 from the dosing inlet 101 and is placed into the dosing area 110, the disassembly assembly can break open the medicine bag and allow the medicine to flow into the dosing chamber 110 under the action of gravity. Within the drug loading area 110, the final flow is from the drug outlet 102 to the sewage tank or drug mixing tank. The water film dust prevention component includes a water film dust removal pipe 300, which is installed on the inner wall of the dust removal pipe installation area 120 and arranged around the circumference of the dust removal pipe installation area 120. The side wall of the water film dust removal pipe 300 is provided with a water outlet 301 for water discharge. During the drug addition process, the water in the water film dust removal pipe 300 can be sprayed from the water outlet 301 onto the sides of the drug pack to form a water film, preventing the spread of drug dust. At the same time, excess water can flow directly along the side wall of the drug loading area 110 to the drug outlet 102 and be directly discharged into the sewage tank or drug mixing tank.
[0043] In addition to the water film dust removal pipe 300, the water film dust prevention assembly also includes a water supply device, a switch valve, and other mechanisms. The water supply device is connected to the water film dust removal pipe 300 to supply water to it. The switch valve is located on the connecting pipe between the water film dust removal pipe 300 and the water supply device to control whether water is discharged from the water film dust removal pipe 300. The water supply device can supply high-pressure water to the water film dust removal pipe 300 to ensure that water can be sprayed onto the chemical pack.
[0044] Compared with related technologies, the dosing device disclosed in this application can effectively reduce the diffusion of drug dust during the dosing process by adding a water film dustproof component, thereby reducing the harm of drug dust to operators and the pollution to the surrounding environment.
[0045] Specifically, to ensure dust protection during the unpacking process, in some embodiments, combined with Figure 3 and Figure 4 There is one water outlet 301, which is arranged along the extension direction of the water film dust removal pipe 300. The water outlet 301 is arranged around the circumference of the dust removal pipe installation area 120, so that water can be sprayed to various positions around the chemical pack during the dosing process to form a water film, ensuring a reliable dust prevention effect.
[0046] In other embodiments, there are multiple water outlets 301, which are arranged at intervals along the extension direction of the water film dust removal pipe 300. At the same time, multiple water outlets 301 are arranged at intervals around the circumference of the dust removal pipe installation area 120. The water flow at each water outlet 301 is sprayed out in a fan shape. By adjusting the number and size of the water outlets 301, it can be ensured that the formed water film completely covers all positions around the medicine pack.
[0047] The aforementioned water film dust removal pipe 300 and dust removal pipe installation area 120 can be an integrated structure or a separate structure. Specifically, when it is a separate structure, the material of the water film dust removal pipe 300 can be the same as or different from that of the dosing chamber 100, and a buckle or other structure can be set on the inner wall of the dust removal pipe installation area 120 to fix the water film dust removal pipe 300. When it is an integrated structure, the water film dust removal pipe 300 can be a metal pipe and is directly welded to the inner wall of the dust removal pipe installation area 120, which has high structural strength and long service life.
[0048] To improve unpacking efficiency, in some embodiments disclosed in this application, combined with Figure 5 and Figure 6The unpacking assembly includes a blade holder 200 and multiple blade bodies 210. The blade holder 200 is disposed within the drug loading area 110. The blade holder 200 includes a puncture post 201 and multiple blade fixing rods 202. The puncture post 201 is provided with a tip for puncturing and breaking open the drug pack. The blade fixing rods 202 are arranged circumferentially around the puncture post 201, and the first end of the blade fixing rod 202 is connected to the puncture post 201, while the second end of the blade fixing rod 202 is connected to the drug loading area 110. Each blade fixing rod 202 is provided with a first mounting groove 203, and each blade body 210 is correspondingly disposed in each of the first mounting grooves 203. The blade body 210 and the first mounting groove 203 can be directly assembled by interference fit. The tip of the puncture column 201 and the blade of the blade body 210 are both positioned towards the drug inlet 101, and the tip of the puncture column 201 is closer to the drug inlet 101 than the blade of the blade body 210. As the drug pack enters the drug loading area 110 from the drug inlet 101, the drug pack is first punctured by the puncture column 201, and then further torn open by the action of each blade body 210. The unpacking efficiency is high, and the resulting opening area is large enough to improve the drug addition efficiency.
[0049] Specifically, in order to open the medicine packet as much as possible to facilitate the outflow of the medicine, combined with Figure 1 and Figure 2 The first mounting groove 203 is arranged along the extension direction of the blade fixing rod 202. At the same time, one end of the blade body 210 abuts against the puncture column 201, and the other end extends to the inner wall of the drug loading area 110. For example, when the cross-section of the drug loading area 110 is a regular rectangular structure, the blade body 210 can be arranged along the diagonal of the drug loading area 110. When the medicine bag is placed into the drug delivery device, it sinks under its own weight. At the same time, the blade body 210 can completely cut the bottom of the medicine bag along the diagonal direction, so that the medicine in the medicine bag can flow completely into the drug loading area 110. This solves the problem of low drug delivery efficiency caused by the medicine at the edge of the ton bag not being able to flow into the drug loading area 110 and the need for repeated manual cutting of the bottom of the ton bag.
[0050] Furthermore, to ensure a reliable connection between the blade body 210 and the blade holder 200, multiple second mounting slots 204 are provided on the outer wall of the piercing post 201. The second mounting slots 204 are arranged along the extending direction of the piercing post 201, and the blade body 210 is embedded into each of the corresponding second mounting slots 204. This simultaneously fixes the blade body 210 through the first mounting slot 203 and the second mounting slot 204, thereby improving the reliability of the connection between the blade body 210 and the blade holder 200. Typically, the piercing post 201 is perpendicular to the blade fixing rod 202 for ease of manufacturing; correspondingly, the first mounting slot 203 and the second mounting slot 204 are arranged perpendicularly.
[0051] The aforementioned puncture post 201 and blade fixing rod 202 can be integrated into a single structure through welding or other methods; the blade fixing rod 202 and the dosing chamber 100 can be fixed by welding, screwing, or other methods. In some embodiments, combined with... Figure 3 Multiple mounting bosses 103 are provided on the inner wall of the drug loading area 110, and the second end of each blade fixing rod 202 is connected to each mounting boss 103 in a one-to-one correspondence. Specifically, mounting slots are provided on the mounting bosses 103, and the blade fixing rods 202 can be directly embedded into the mounting slots for positioning and installation.
[0052] The outlet 102 is usually smaller than the inlet 101, combined with Figure 3 The bottom of the drug-carrying area 110 can be a trapezoidal structure or a conical structure.
[0053] Combination Figure 2 A screen 130 can also be installed at the drug outlet 102. This application does not limit the material of the screen 130. For example, the screen 130 can be made of stainless steel, and the mesh size of the screen 130 can be set according to the actual situation, such as 1 mesh to 4 mesh, as long as it can prevent large drug blocks or drug bag fragments from entering the sewage tank or drug mixing tank during the drug addition process.
[0054] To achieve stable placement of the dosing chamber 100, combined with Figure 1 and Figure 7 The dosing device also includes a dosing tank support 400, on which the dosing tank 100 is mounted. The dosing tank support 400 has a dosing tank connection hole 401 for bolting the dosing tank 100, and a support fixing hole 402 for fixing to the ground or other mounting foundation. This allows it to support and secure the dosing tank 100, preventing it from moving or tipping over during dosing. The dosing tank support 400 can be made of round or square stainless steel tubing, resulting in a simple structure and low cost.
[0055] In some embodiments, the dust removal pipe installation area 120 includes an installation platform disposed on top of the drug loading area 110, and a surrounding sidewall disposed circumferentially around the top of the installation platform. The installation platform is used to install the water film dust removal pipe 300. The area enclosed by the sidewall is defined as the enclosure area, which can reduce the spillage of medicine into the surrounding environment during the dosing process. To facilitate fixing with the drug storage bracket 400, the cross-sectional area of the enclosure area is larger than the cross-sectional area of the drug loading area 110, so as to form a stepped structure at the connection between the drug loading area 110 and the dust removal pipe installation area 120, so that the drug storage bracket 400 can be welded or bolted to the bottom of the installation platform.
[0056] In some embodiments, different parts of the dosing chamber 100 can be welded from stainless steel plates with a thickness of 2mm-3mm. The inlet 101 can be circular or rectangular, and the outlet 102 is shaped to match the dosing port of the sewage tank or chemical mixing tank. The outlet 102 can extend into the sewage tank or chemical mixing tank, and the chemical can enter the sewage tank or chemical mixing tank through the outlet 102. The dust removal pipe installation area 120 is square or circular, with a length of 1050mm-1550mm or a diameter of 1050mm-1550mm and a height of 50mm-100mm. The top area of the chemical loading area 110 has a length of 1000mm-1500mm or a diameter of 1000mm-1500mm and a height of 100-300mm to ensure that the bottom of the ton bag is completely covered to prevent the chemical from spilling out during the dosing process. The bottom of the chemical loading area 110 is trapezoidal or conical.
[0057] Mounting bosses 103 are provided at the four corners or around the perimeter of the drug loading chamber 100. Rectangular mounting slots are formed on the mounting bosses 103, with the width of the slots matching the dimensions of the blade fixing rod 202, a length of 50mm-200mm, and a depth of 5mm-15mm. The diameter of the puncture post 201 is 30mm-50mm. The width of the first mounting slot 203 and the second mounting slot 204 matches the thickness of the blade body 210, which can be 2mm-5mm, and the depth is 8mm-15mm. The blade body 210 is made of high-strength stainless steel, with a thickness of 2mm-5mm. The cutting edge of the blade body 210 is triangular or an irregular arc shape. There are four blade bodies 210, symmetrically installed along the diagonal direction of the drug loading area 110.
[0058] The water film dust removal pipe 300 is made of high-strength stainless steel or high-strength hard plastic, with a diameter of 15mm-40mm and a wall thickness of 2mm-3mm. The water inlet 310 of the water film dust removal pipe 300 is connected to a high-pressure water pump. The end of the water film dust removal pipe 300 is sealed. The pipe wall of the water film dust removal pipe 300 has a 0.2mm-1mm gap in the horizontal direction, which is used as the water outlet 301 to form a water film and prevent the spread of pharmaceutical dust.
