Description

Technical Field

[0001] This utility model relates to the field of yellow phosphorus slag treatment technology, specifically to a water filtration device for yellow phosphorus slag. Background Technology

[0002] In the industrial production of thermal yellow phosphorus, the treatment of slag generated after the high-temperature reaction of ore, coke, and silica in the furnace has always been a key challenge for the industry. Currently, water quenching is the mainstream method for slag treatment. Although it can achieve preliminary cooling of the slag, transforming it into grayish-white fine particles of 0.2-0.5 mm with a certain relative density (approximately 2.89) and a specific moisture content (1%-10%), and can find applications in the building materials field, it has many serious technical defects in subsequent slag filtration and processing.

[0003] Traditional overhead crane grab filtration methods are extremely inefficient, failing to effectively remove excess moisture from slag. This results in persistently high slag moisture content, severely limiting its application efficiency and quality stability in building materials and other fields. Even more serious is the uncontrolled emission of large amounts of flue gas into the surrounding environment during both the grabbing process and the slag storage phase. This flue gas is rich in various harmful pollutants, such as unburned carbon particles, sulfur oxides, and phosphates. These pollutants diffuse freely in the air, causing irreversible pollution to the surrounding atmosphere, eroding soil and water sources, disrupting the ecological balance, and directly harming the respiratory and cardiovascular health of on-site workers. This can lead to coughs, asthma, lung diseases, and even more serious occupational illnesses, severely violating modern industrial environmental protection and health safety principles.

[0004] Furthermore, in the logistics and transportation process, loading slag at the stockpile requires a significant amount of manpower and resources. This cumbersome process greatly increases production and time costs, severely hindering the efficient operation of the production process and the sustainable development of the industry.

[0005] In summary, existing slag treatment technologies have significant problems in terms of filtration efficiency, environmental performance, and logistics efficiency. Utility Model Content

[0006] The purpose of this utility model is to provide a water filtration device for yellow phosphorus slag. The device is designed with a cylindrical upper part and a conical lower part to facilitate the filtration of slag moisture and the outflow of filter residue. The device is equipped with a first filtration component to ensure the filtration effect of the slag. At the same time, the device is located at a certain height from the ground, which also facilitates the transfer and loading of slag.

[0007] This utility model is achieved through the following technical solution:

[0008] A water filtration device for yellow phosphorus residue, comprising:

[0009] The silo shell is erected above the ground, and the upper part of the silo shell is a cylindrical structure, while the lower part of the silo shell is a conical structure.

[0010] A filtration device includes a first filtration component. One end of the first filtration component is detachably mounted on the top of the hopper housing via a fixing component. The other end of the first filtration component extends into the hopper housing along the axial direction of the hopper housing. The other end of the first filtration component discharges the water collected in the first filtration component to the outside of the hopper housing through a central drain pipe.

[0011] In this design, the upper part of the silo shell is cylindrical, while the lower part is conical, providing a stable spatial structure for the entire filtration process. The conical structure helps guide the filtered slag to flow out smoothly, avoiding blockages. The first filter component in the filtration device is connected to the top of the silo shell via a fixing component. This detachable connection facilitates installation, maintenance, and replacement, ensuring effective filtration. Extending inward along the silo axis and draining water via a central drain pipe, it accurately collects and discharges moisture, thereby achieving effective filtration of yellow phosphorus slag and improving the efficiency and quality of slag treatment.

[0012] As an optimized solution for the water filtration device, the filtration device further includes a second filtration assembly, which is provided in multiples and distributed on the lower outer surface of the hopper housing.

[0013] In this scheme, since the slag may flow from different directions and positions during the yellow phosphorus slag filtration process, this layout of the second filter component can ensure effective filtration of the slag from all angles, avoiding problems such as water residue or impurity leakage caused by insufficient local filtration. This further ensures the efficient and stable operation of the water filtration device, improves the precision and quality of phosphorus slag treatment, enhances the adaptability of the device to complex working conditions, and enables the device to achieve more ideal filtration performance when processing yellow phosphorus slag.

[0014] As an optimized solution for the water filtration device, the second filtration component includes an external drain pipe and an external filter screen. The external filter screen is connected to the lower outer shell surface of the hopper housing and discharges the collected water through the external drain pipe.

[0015] In this design, the external filter effectively intercepts impurities in the slag, preventing them from being discharged with the water flow and causing environmental pollution or subsequent treatment problems. When water in the slag passes through the external filter, the intercepted impurities remain on the filter surface, while the filtered water smoothly enters the connected external drain pipe. The external drain pipe provides a dedicated discharge channel for water, ensuring that water can be discharged from the hopper shell in a timely and orderly manner, maintaining the water flow balance and filtration efficiency within the device, and preventing water accumulation from affecting the filtration effect or causing device malfunction.

[0016] As an optimized solution for the water filtration device, the fixing component includes a central filter screen fixing bracket and a central filter screen handle, and the first filtration component includes a central filter screen;

[0017] The lower end of the central filter screen fixing bracket is fixed to the top of the hopper shell, the central filter screen passes through the middle of the central filter screen fixing bracket and is snapped into the upper end of the central filter screen fixing bracket, and the central filter screen handle is connected to the snapped end of the central filter screen.

[0018] In this design, the fixed connection between the lower end of the central filter screen mounting bracket and the top of the hopper shell provides a stable support foundation for the central filter screen, ensuring its position remains fixed during filtration and effectively resisting the impact of slag and water flow. The method of the central filter screen passing through the middle of the mounting bracket and snapping onto the upper end ensures both the secure installation of the filter screen and facilitates disassembly, maintenance, or replacement when necessary. Furthermore, the handle connected to the snap-on end of the central filter screen provides operators with a convenient operating point, allowing for quick and safe removal of the central filter screen from the device for cleaning or replacement in emergencies such as severe filter clogging affecting filtration efficiency, or during routine maintenance.

[0019] As an optimized solution for the water filtration device, a central filter support is connected to the junction of the upper and lower parts of the hopper shell and the extension end of the first filter component.

[0020] In this design, the support base is installed at the junction of the upper and lower parts of the silo shell and at the extended end of the first filter assembly, providing a stable support structure for the first filter assembly. During operation of the water filtration device, the flow of slag and the impact of water flow exert significant forces on the first filter assembly. The central filter screen support base effectively resists these external forces, preventing the first filter assembly from shaking, shifting, or deforming. By maintaining the stability of the first filter assembly, its filtration accuracy and effectiveness are ensured to remain unaffected.

[0021] As an optimized solution for the water filtration device, the cone angle of the lower conical structure of the silo shell is between 40° and 50°.

[0022] In this design, this angle range ensures that the slag flows out of the bottom of the device at a relatively ideal speed and smoothness under gravity. If the angle is too small, the slag is prone to accumulate and clog the bottom of the cone, hindering the filtration process; if the angle is too large, it may cause the slag flow rate to be too fast, affecting the filtration effect, or even causing insufficiently filtered slag to be discharged prematurely. A suitable cone angle ensures smooth slag discharge while helping to maintain stable filtration efficiency, enabling the entire water filtration device to operate efficiently and stably when treating yellow phosphorus slag.

[0023] As an optimized solution for the water filtration device, a hopper is provided at the bottom of the silo shell, and the hopper is equipped with a hydraulic electric valve, so that the filter residue after water filtration can flow out of the silo shell through the hopper.

[0024] In this design, after the yellow phosphorus slag filtration process is completed, the filtered residue, having released its moisture, flows out of the silo shell in an orderly manner through the hopper. Hydraulic electric valves precisely control the timing and flow rate of the filter residue discharge, effectively preventing leakage and overflow, and ensuring the cleanliness and safety of the surrounding environment.

[0025] As an optimized solution for the water filtration device, the upper outer shell of the silo housing is connected to an overflow port.

[0026] In this scheme, during the filtration of yellow phosphorus slag, when the amount of slag entering the silo exceeds a certain limit, the excess slag can be discharged through the overflow port. This effectively prevents excessive accumulation of slag in the silo, avoids clogging problems that may be caused by excessive slag accumulation, and ensures that the filtration device can operate continuously and stably, maintaining normal filtration efficiency.

[0027] As an optimized solution for the water filtration device, the upper outer shell of the silo is connected to a feed inlet, which is located above the overflow port. The water-quenched slag is drawn through a pipeline to the feed inlet and then enters the device.

[0028] As an optimized solution for water filtration devices, all of the aforementioned filtration devices are equipped with a backwashing cleaning device.

[0029] In this solution, when filtering yellow phosphorus slag, impurities in the slag easily adhere to the filter device, causing the filter screen to become clogged over time, which seriously affects the filtration efficiency. The backwashing device can periodically or according to the actual working conditions backwash the filter device, using the powerful water flow to flush away the impurities clogging the filter screen pores, so that the filter device can quickly restore good filtration performance.

[0030] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0031] 1. In terms of filtration effect, this utility model greatly improves the filtration capacity for yellow phosphorus slag by combining the upper cylinder and the lower cone, as well as the synergistic effect of the first and second filter components. It can effectively reduce the moisture content of the slag and overcome the shortcomings of poor moisture removal in the traditional overhead crane grab bucket filtration method.

[0032] 2. In terms of environmental performance, the relative sealing of the device effectively reduces the generation of flue gas during slag filtration and stacking, avoids the pollution of the atmosphere, soil and water by harmful pollutants, protects the health of workers and improves the production environment.

[0033] 3. In terms of logistics and transportation, this utility model, due to the design of the hopper with hydraulic electric valve at the bottom of the silo and a certain height above the ground, allows the filtered slag to flow into the transfer equipment conveniently without the need for additional complicated loading operations, saving a lot of manpower and material resources and significantly improving production efficiency.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0040] Example 1

[0041] This embodiment 1 provides a water filtration device for yellow phosphorus residue, such as... Figures 1-2 As shown, it includes a hopper housing 10 and a filter device;

[0042] like Figure 1As shown, the silo shell 10 is erected above the ground. The upper part of the silo shell 10 is a cylindrical structure. An overflow port 6 and a feed port 7 are connected to the upper outer shell. The feed port 7 is located above the overflow port 6. The water-quenched slag is drawn through the pipeline to the feed port 7 and enters the storage space inside the silo shell 10. When the amount of slag entering the silo exceeds a certain limit, the excess slag can be discharged through the overflow port 6. The lower part of the silo shell 10 is a conical structure with a cone angle between 40° and 50°. In order to make the slag flow out from the bottom of the device at a more ideal speed and smoothness, the cone angle in this embodiment is set at 45°, so that the filtered slag flows out smoothly and quickly under the action of gravity, effectively preventing blockage.

[0043] Meanwhile, a hopper 1 is connected to the bottom of the silo shell 10. The hopper 1 is equipped with a hydraulic electric valve. The filter residue after the water has been filtered can flow out of the silo shell 10 through the hopper. At the same time, since the silo shell 10 is at a certain height from the ground, the slag flowing out of the hopper 1 can be easily loaded and transported.

[0044] See also Figure 1 As shown, the above-mentioned filtration device includes a first filtration component. One end of the first filtration component is detachably mounted on the top of the hopper housing 10 via a fixing component. The other end of the first filtration component extends into the hopper housing 10 along the axial direction of the hopper housing 10. The other end of the first filtration component discharges the water collected in the first filtration component out of the hopper housing 10 through the central drain pipe 2. Specifically, the fixing component includes a central filter screen fixing bracket 8 and a central filter screen handle 9. The first filtration component includes a central filter screen 5. The lower end of the central filter screen fixing bracket 8 is fixed to the top of the hopper housing 10. The central filter screen 5 passes through the middle of the central filter screen fixing bracket 8 and is snapped into the upper end of the central filter screen fixing bracket 8. The central filter screen handle 9 is connected to the snap-in end of the central filter screen 5. In this way, the filter screen is installed firmly and it is easy to disassemble, maintain or replace it when needed. In an emergency, such as when the filter screen is seriously clogged and affects the filtration effect, or during regular maintenance, the central filter screen 5 can be quickly and safely removed from the device for cleaning or replacement.

[0045] Here, since the flow of slag and the impact of water flow will exert a large force on the first filter component when the water filtration device is running, a central filter support 11 is connected to the junction of the upper and lower parts of the hopper shell 10 and the extension end of the first filter component. The central filter support 11 can effectively resist these external forces and prevent the first filter component from shaking, displacing or deforming.

[0046] Meanwhile, in this embodiment, since the slag may flow from different directions and positions during the yellow phosphorus slag filtration process, to ensure effective filtration of the slag from all angles, therefore, as follows: Figure 2As shown, the filtration device also includes a second filtration assembly. Four sets of the second filtration assembly are arranged along the axis of the silo shell 1 on the lower outer surface of the silo shell 10. Specifically, each set of the second filtration assembly includes three external drain pipes 3 and three external filter screens 4. All external filter screens 4 are connected to the lower outer surface of the silo shell 10 and discharge the collected water from the corresponding external drain pipes 3, thereby ensuring the filtration effect of the slag and timely removing the moisture in the slag.

[0047] Example 2

[0048] This embodiment 2 provides a water filtration device for yellow phosphorus slag based on the solution of embodiment 1, such as... Figures 1-2 As shown, both the first and second filter components are equipped with backwashing devices. These backwashing devices are existing technologies, such as the Boyuan brand BY-FQ series backwashing devices or the Ruitong RT-ZX series backwashing devices, which use high-pressure water jet, air-water combination, or pulse technology principles. The backwashing devices can prevent the filter screen from clogging.

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
