Description

Technical Field

[0001] This utility model relates to the field of wastewater pretreatment technology in slaughterhouses, specifically to a wastewater recycling device for slaughterhouses. Background Technology

[0002] The slaughtering industry generates large amounts of wastewater during production. This wastewater typically contains high concentrations of organic matter, suspended solids, and grease, and is especially rich in long, fine hairs and soft animal viscera membranes. These impurities are prone to entanglement and are difficult to settle, posing a serious challenge to subsequent wastewater treatment units, such as biological treatment and membrane separation. They can easily cause blockages in pipes, pumps, and treatment equipment, significantly increasing system maintenance frequency and operating costs.

[0003] Currently, the pretreatment stage of slaughterhouse wastewater mostly uses bar screens or filters for initial interception. However, when conventional bar screens or fixed filters are used to intercept the aforementioned fine hairs and soft inner membranes, the filters are easily clogged by impurities that adhere tightly and become entangled, leading to a rapid decrease in water flow capacity. To ensure treatment efficiency, frequent shutdowns are required for manual cleaning or filter replacement, which not only significantly reduces the continuity and efficiency of wastewater treatment but also increases the labor intensity of operators.

[0004] Therefore, we propose a wastewater recycling device for slaughterhouses. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a wastewater recycling device for slaughterhouses. By having two flip-up filter structures work alternately, it achieves continuous filtration without stopping the machine and convenient cleaning, effectively solving the problems of easy clogging and frequent cleaning of filter screens in the pretreatment of slaughterhouse wastewater. This can effectively solve the problems in the background technology.

[0006] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: a wastewater recycling device for slaughterhouses, comprising two sets of supports. A first filter structure and a second filter structure are installed on the upper part between the two sets of supports, and the second filter structure is located below the first filter structure. The second filter structure has the same composition as the first filter structure. Both the first filter structure and the second filter structure include a driven shaft, a transmission box, a drive motor, a connecting arm, a rectangular frame, an arc-shaped filter screen, a worm gear, and a worm. The driven shaft is connected between the two sets of supports, and the transmission box is fixed on the outer surface of one side of one set of supports, with one end of the driven shaft extending into the interior of the transmission box.

[0007] Preferably, the first filter structure has two sets of connecting arms; the two sets of connecting arms are fixed to the outer walls at both ends of the driven shaft, and the ends of the two sets of connecting arms away from the driven shaft are fixedly connected to the left and right ends of the outer surface of one side of the rectangular frame.

[0008] Preferably, the arc-shaped filter screen is fixed to the lower outer surface of the rectangular frame.

[0009] Preferably, the drive motor is fixed to the bottom of the front outer surface of the transmission box, the worm and the worm wheel are both located inside the transmission box, a coupling is provided between the worm and the drive motor, and one end of the outer surface of the worm is fixedly connected to one end of the outer surface of the output shaft of the drive motor through the coupling.

[0010] Preferably, the worm wheel is located at the upper part of the worm, and the upper outer surface of the worm meshes with the lower outer surface of the worm wheel; the worm is a single-start worm, and the worm lead angle is less than the equivalent friction angle, so that the worm wheel cannot drive the worm in the reverse direction, thereby achieving mechanical self-locking.

[0011] Preferably, the worm gear is fixed to the outer wall of one end of the driven shaft, and bearings are provided between the driven shaft and the transmission box and the bracket. The driven shaft is rotatably connected to the transmission box and the bracket through the bearings.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a wastewater recycling device for slaughterhouses, which has the following beneficial effects: 1. This wastewater recycling device for slaughterhouses features a first and a second filter structure arranged vertically and identically, with an independent drive mechanism controlling the rotation of the arc-shaped filter screen. This allows the two filter structures to alternately engage in filtration and cleaning / maintenance operations. When one filter structure needs cleaning due to excessive debris, it can immediately switch to the other filter structure to continue working. This avoids the problem of having to stop the machine to intercept the flow due to filter screen cleaning in existing technologies, ensuring the continuity of the wastewater pretreatment process and improving the overall treatment efficiency of the system.

[0013] 2. This wastewater recycling device for slaughterhouses, through the design of a drive motor, worm gear transmission mechanism and connecting arm, can flip the filter screen, which was originally used to collect debris with its opening facing upwards, to a state with its opening facing downwards. This allows the trapped hair, inner membrane and other debris to be automatically dumped under the action of gravity, while also facilitating auxiliary cleaning or rinsing by operators, thus solving the problems of difficult, time-consuming and labor-intensive cleaning of traditional fixed filter screens.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a wastewater recycling device for slaughterhouses, comprising two sets of parallel supports 1. Between the two sets of supports 1, a first filter structure 2 and a second filter structure 3 are installed sequentially from top to bottom. The first filter structure 2 and the second filter structure 3 have identical structural components, each including a driven shaft 4, a transmission box 5, a drive motor 6, a connecting arm 7, a rectangular frame 8, an arc-shaped filter screen 9, a worm gear 10, and a worm 11.

[0021] Driven shaft 4 is rotatably connected between two sets of brackets 1 via bearings. Transmission box 5 is fixedly installed on the outside of one set of brackets 1, with one end of driven shaft 4 extending into the transmission box 5. The first filter structure 2 has two sets of connecting arms 7, which are respectively fixed to the outer walls at both ends of driven shaft 4, and the ends of the two sets of connecting arms 7 away from driven shaft 4 are fixedly connected to the left and right ends of the outer surface of one side of rectangular frame 8. Arc-shaped filter screen 9 is fixedly installed on the lower outer surface of rectangular frame 8, thus forming a filter surface capable of collecting impurities from wastewater.

[0022] The drive motor 6 is fixedly mounted on the bottom of the front outer surface of the transmission housing 5. Both the worm 11 and the worm wheel 10 are housed inside the transmission housing 5. The worm 11 is fixedly connected to the output shaft of the drive motor 6 via a coupling. The worm wheel 10 is fixedly fitted onto the outer wall of the end of the driven shaft 4 that extends into the transmission housing 5, and is located above the worm 11. The worm 11 and the worm wheel 10 mesh with each other to form a worm gear transmission pair.

[0023] In this embodiment, the worm 11 is preferably a single-start worm, and its lead angle is smaller than the equivalent friction angle. This design gives the worm gear transmission a self-locking characteristic, meaning that the worm wheel 10 cannot drive the worm 11 in the reverse direction, thereby ensuring that the arc-shaped filter screen 9 can be reliably locked at any rotation angle, preventing accidental rotation due to water flow impact or load, and ensuring the stability and safety of equipment operation.

[0024] Working principle and process: Initial state or a certain work cycle, such as Figure 1 As shown, at this time, the arc-shaped filter screen 9 in the first filter structure 2 has its opening facing upwards and is in the working position, used to intercept suspended impurities such as hair and inner membrane in the wastewater. Meanwhile, the arc-shaped filter screen 9 in the second filter structure 3 has its opening facing downwards and is in the cleaning position, which facilitates the final cleaning of residual impurities attached to it or prepares it for operation.

[0025] When the first filter structure 2 has been working for a period of time and the impurities intercepted on its arc-shaped filter screen 9 reach a certain amount and need to be cleaned, follow these steps: 1. Activate the standby filter unit: Start the drive motor 6 of the second filter structure 3. The drive motor 6 drives the worm gear 11 to rotate via a coupling. The worm gear 11 drives the meshing worm wheel 10 to rotate, and the worm wheel 10 drives the driven shaft 4 to rotate. The driven shaft 4 drives the rectangular frame 8 and the arc-shaped filter screen 9 fixed on it to rotate counterclockwise as a whole around the axis of the driven shaft 4 (towards...). Figure 1 (Perspective). Until the arc-shaped filter 9 in the second filter structure 3 flips to the working position with the opening facing upwards, as shown. Figure 2 The state shown is as follows. At this time, the second filter structure 3 replaces the first filter structure 2 to receive and filter the wastewater, ensuring that the filtration process is continuous and uninterrupted.

[0026] 2. Cleaning the saturated filter unit: After the second filter structure 3 is put into operation, the drive motor 6 of the first filter structure 2 is immediately started. Similarly, through the transmission of its internal worm gear 11, worm wheel 10, driven shaft 4, and connecting arm 7, the rectangular frame 8 and arc-shaped filter screen 9 of the first filter structure 2 are driven to rotate counterclockwise. This flips it from the working position with the opening facing upwards to the cleaning position with the opening facing downwards. In this position, most of the impurities trapped on the arc-shaped filter screen 9 can automatically fall off under gravity. Operators can also easily perform auxiliary cleaning, such as rinsing with water or manually removing tangled materials; the cleaning process is simple and labor-saving.

[0027] By controlling the start, stop, and direction of the drive motors 6 in the two filter structures, the alternating switching between the working and cleaning states of the first filter structure 2 and the second filter structure 3 can be achieved. This design ensures that at least one filter unit is in an effective working state at all times, enabling continuous operation of the wastewater pretreatment system without shutdown, improving treatment efficiency, and reducing maintenance intensity and frequency.
