Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, in particular to a high-speed spiral slag filtering device for kitchen waste sewage. Background Technique

[0002] Kitchen waste sewage is the wastewater generated in the catering industry, household kitchens, and food processing processes. This kind of sewage usually contains a large amount of organic substances, solid suspended matters, and components such as high-concentration ammonia nitrogen. If kitchen waste sewage is directly discharged without treatment, it will cause serious pollution to the environment and affect the water quality of water bodies and the ecological balance.

[0003] Aeration and slag scraping is a common technology for treating kitchen waste sewage, mainly used for the removal and treatment of grease and suspended solids in sewage. During the aeration process, through the action of bubbles, it assists in the precipitation and separation of solid suspended matters, making them deposit at the bottom of the sewage, reducing the turbidity and suspended solid content in the sewage.

[0004] However, for particularly high-concentration grease or solid suspended solids, aeration and slag scraping cannot completely remove all pollutants, requiring additional treatment steps, increasing the treatment time, and it is difficult to achieve sustainable and efficient sewage treatment effects. Content of the Utility Model

[0005] In order to overcome the above deficiencies, the purpose of the utility model is to provide a high-speed spiral slag filtering device for kitchen waste sewage, which can elastically adjust the continuous water inflow according to the fine slag content in the sewage, and is not limited to batch water inflow, and then discharges the slag through the slag discharge guide rod to realize the function of automatic slag discharge.

[0006] The present application discloses a high-speed spiral slag filtering device for kitchen waste sewage, including:

[0007] A frame, a slag filtering component, a feeding component, a slag discharging component, and a water collecting component all arranged on the frame; among them

[0008] The slag filtering component includes a rotating shaft that can rotate around an axis, a screen sleeve arranged outside the rotating shaft, a spiral blade arranged on the rotating shaft and located inside the screen, and a slag discharge guide rod arranged on the rotating shaft and located inside the screen;

[0009] The rotating shaft has a first end and a second end opposite to each other along its own axis; the first end of the rotating shaft is adjacent to the feeding component, so that the feeding component is used to input kitchen waste into the slag filtering component; the second end of the rotating shaft is adjacent to the slag discharging component, so that the slag discharging component is used to receive the solid waste output by the slag filtering component;

[0010] Among them, the spiral blade is closer to the first end of the rotating shaft than the slag discharge guide rod;

[0011] The overall of the slag discharge guide rod extends along the axial direction of the rotating shaft;

[0012] The water collection assembly is located below the screen and is used to receive the liquid waste output by the filter residue assembly;

[0013] The motor assembly is used to drive the spiral blade to operate.

[0014] With the above structure, the utility model inputs the kitchen waste sewage into the feeding assembly, and then enters the filter residue assembly. The spiral blade and the slag discharge guide rod are integrally formed. Driven by the motor assembly, the spiral blade starts to rotate. Inside the filter residue assembly, the sewage is first stirred and extruded by the spiral blade. After extrusion, the sewage is separated into solid waste and liquid waste with less residue particles. The liquid waste is discharged from the screen and collected by the water collection assembly. The solid waste formed by the extrusion of the sewage by the spiral blade is discharged into the slag discharge guide rod and finally discharged from the slag discharge assembly out of the filter residue device.

[0015] Further, the water collection assembly is in a funnel-shaped structure with a larger upper part and a smaller lower part. The sewage discharged from the filter residue assembly enters the water collection assembly. The funnel-shaped design of the water collection assembly helps to guide the liquid waste to be concentrated downward for collection, improving the collection efficiency.

[0016] Further, the slag discharge guide rod is linear. The linear structure reduces complex corners and bends, can effectively push the solid waste towards the slag discharge end, ensures the smooth movement of the solid waste during rotation, reduces the risk of blockage of the solid waste during the diversion process, and improves the stability and operation efficiency of the device.

[0017] Further, the slag discharge guide rod forms a preset angle with the axis of the rotating shaft, and the preset angle is not 0°. By setting a preset angle, the solid waste can be more effectively guided away from the area around the rotating shaft, avoiding the accumulation of solid waste around the rotating shaft, and thus improving the efficiency of the entire slag discharge system.

[0018] Further, the number of the slag discharge guide rods is two, and the two slag discharge guide rods are located on the opposite sides of the rotating shaft. The two slag discharge guide rods are located on the opposite sides of the rotating shaft, balancing the weight distribution of the rotating system, reducing vibration and imbalance phenomena, and improving the stability of the system.

[0019] Further, the two slag discharge guide rods are symmetrically arranged. The symmetrical arrangement can evenly disperse the discharge pressure of the solid waste, reduce the possible blockage phenomenon during the slag discharge of a single-side guide rod, and ensure the smoothness of the slag discharge process.

[0020] Further, at least one of the slag discharge guide rods is connected to the spiral blade. By connecting with the spiral blade, the slag discharge guide rod can more precisely control the discharge path of the solid waste, enabling the solid waste to be smoothly discharged along a predetermined path and optimizing the discharge effect.

[0021] Further, the arc surface of the spiral blade is smoothly connected to the guiding surface of the slag discharge guide rod connected thereto. The smooth connection can ensure that there are no obvious gaps or protrusions between the spiral blade and the slag discharge guide rod, providing a more coherent surface, making it difficult for solid waste to accumulate at the connection, reducing the resistance of the solid waste during transfer, and optimizing the slag discharge effect.

[0022] Further, the number of rotation turns of the spiral blade is between 1 and 4 turns. By reasonably setting the number of rotation turns, the slag discharge capacity of the slag filtering device can be optimized and the working efficiency can be improved.

[0023] Further, the length of the spiral blade along the axis direction of the rotation axis is greater than the length of the outlet end of the feeding component along the axis direction of the rotation axis. The setting of the length of the spiral blade can extend the residence time of the kitchen waste sewage at the spiral blade, which helps to more evenly disperse the kitchen waste sewage.

[0024] The beneficial effects of the present utility model are as follows:

[0025] (1) The high-speed spiral slag filtering device for kitchen waste sewage of the present utility model can continuously intake water, has a large processing capacity, and is not limited to batch intake of water for batch treatment of sewage;

[0026] (2) The slag discharge guide rod adopts a spiral and special slag discharge mechanism design for filtering fiber fine slag;

[0027] (3) It can elastically adjust the continuous water intake according to the content of fine slag in the sewage;

[0028] (4) It has the function of automatic slag discharge. Description of the Drawings

[0035] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0036] In order to solve the problem of low efficiency in treating kitchen waste sewage in the prior art, the present utility model provides a high-speed spiral slag filtering device for kitchen waste sewage. As Figure 1 and Figure 2As shown in the figure, the high-speed spiral slag filtering device for kitchen waste sewage of the present utility model includes: a frame 1, a slag filtering component 2, a feeding component 3, a slag discharging component 4, a water collecting component 5, and a motor component 6, all of which are arranged on the frame 1; wherein, the slag filtering component 2 includes a rotating shaft that can rotate around an axis, a screen 21 sleeved outside the rotating shaft, a spiral blade 22 arranged on the rotating shaft and located inside the screen 21, and a slag discharging guide rod 23 arranged on the rotating shaft and located inside the screen 21; the rotating shaft has a first end and a second end opposite to each other along its own axis; the first end of the rotating shaft is adjacent to the feeding component 3, so that the feeding component 3 is used to input kitchen waste into the slag filtering component 2; the second end of the rotating shaft is adjacent to the slag discharging component 4, so that the slag discharging component 4 is used to receive the solid waste output by the slag filtering component 2; wherein, the spiral blade 22 is closer to the first end of the rotating shaft than the slag discharging guide rod 23; the whole of the slag discharging guide rod 23 extends towards the axis direction of the rotating shaft; the water collecting component 5 is located below the screen 21 and is used to receive the liquid waste output by the slag filtering component 2; the motor component 6 is used to drive the spiral blade 22 to operate.

[0037] According to the above structure, pour the kitchen waste sewage into the feeding component 3. Under the action of the motor component 6, the spiral blade 22 is synchronously driven to rotate, stirring and squeezing the sewage. The solid waste in the sewage is squeezed and discharged from the slag discharging component 4, while the liquid waste squeezed out by the spiral blade 22 is discharged from the screen 21 and falls into the water collecting component 5 for unified collection and treatment.

[0038] Specifically, the slag filtering component 2 includes a rotating shaft that can rotate around an axis. A spiral blade 22 and a slag discharging guide rod 23 are arranged on the rotating shaft, and the spiral blade 22 and the slag discharging guide rod 23 are integrally formed. The rotating shaft has a first end and a second end. The spiral blade 22 is closer to the first end, and the slag discharging guide rod 23 extends towards the second end along the direction of the rotating shaft. When the kitchen waste sewage enters the slag filtering device, the spiral blade 22 first stirs and squeezes the sewage, performing solid-liquid separation on the sewage. The liquid waste is directly discharged from the screen 21 due to gravity, while the solid waste is squeezed by the spiral blade 22 and then discharged into the part of the slag discharging guide rod 23, and finally discharged from the slag discharging component 4 through rotation.

[0039] The design of the above high-speed spiral slag filtering device for kitchen waste sewage usually requires relatively low energy consumption when treating sewage, and the operation and maintenance costs are relatively reduced. It can be applied to treat sewage with different concentrations and characteristics, and has a more obvious effect on treating sewage with high-concentration fixed suspended solids and grease.

[0040] In this embodiment, as Figure 2As shown, the water collection component 5 of the high-speed spiral slag filtering device for kitchen waste sewage is in a funnel-shaped structure with a larger upper part and a smaller lower part. The water collection component 5 is located directly below the screen 21. When the kitchen waste sewage is squeezed and the sewage with a small amount of filter residue is discharged from the screen 21, it enters the water collection component 5 and is collected and processed uniformly.

[0041] In this embodiment, as Figure 3 and Figure 4 shown, the slag discharge guide rod 23 is linear and forms a preset angle with the rotating shaft it is on. The preset angle is not 0°. The setting of the preset angle makes it inclined, which helps to guide the solid waste to be discharged, optimizes the discharge path of the solid waste, and makes it smoother. The preset angle can be set according to needs or actual requirements. Preferably, the preset angle is an acute angle, and the preset angle can be 3°, 5°, or 10°. The number of the slag discharge guide rods 23 is two, located on the opposite sides of the rotating shaft, and is symmetrically arranged with respect to the rotating shaft. Among them, at least one slag discharge guide rod 23 is connected to the spiral blade 22, and the arc surface of the spiral blade 22 is smoothly connected to the guiding surface of the slag discharge guide rod 23 connected to it. The preliminarily treated kitchen waste becomes solid waste and is introduced into the slag discharge guide rod 23. The above design can provide guidance and stable transmission when the solid waste flows.

[0042] In this embodiment, as Figure 2 and Figure 3 shown, the length of the spiral blade 22 in the axial direction of the rotating shaft is greater than the length of the outlet end of the feeding component 3 in the axial direction of the rotating shaft. And within this length range, the number of rotation circles of the spiral blade 22 is between 1 and 4. When the kitchen waste wastewater enters the feeding component 3, it is stirred and solid-liquid separated by the spiral blade 22. The setting of the length of the spiral blade 22 ensures that it can provide more extrusion or stirring time, so that the kitchen waste sewage can be stirred more fully in the slag filtering device, and thus the solid-liquid separation is realized.

[0043] So far, the technical solution of the present invention has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
