[0045] Combination Figures 1-5 As shown, this embodiment of the present disclosure provides a pre-cleaning device for hydrolyzed feather powder, including: a box body 11, a plurality of stirring rollers 12, a first motor 13, a belt conveyor 14, a lower support plate 17, a first dewatering pressure roller 16, and a scraper assembly 15;
[0046] The housing 11 includes a washing section 111 and a dewatering section 112. The dewatering section 112 is located on one side of the washing section 111 and extends upward at an angle. An inlet is located on the other side of the washing section 111, and an outlet is located on the upper side of the dewatering section 112. Specifically, the washing section 111 is located on the right side of the housing 11, and the dewatering section 112 is located on the upper left side of the housing 11. The two sections are interconnected. The housing 11 can be fixed to the ground by a bracket, which is a combination of metal tubes of different lengths, a conventional technique in this field.
[0047] Multiple agitator rollers 12 are rotatably mounted in the cleaning section 111 of the housing 11, with one end connected to each other via a drive wheel (pulley or sprocket). The agitator rollers 12 rotate within the cleaning section 111, thoroughly agitating and dispersing the feathers, effectively preventing tangling and accumulation, and ensuring that the water flow fully contacts and removes impurities such as mud and grease trapped inside the feathers. The agitator rollers 12 can be arranged in a single row or in double rows, with the number in each row determined by the length of the cleaning section 111.
[0048] The first motor 13 is mounted on the housing 11 and is coaxially connected to any one of the stirring rollers 12 to drive its rotation; the first motor 13 is a geared motor.
[0049] A belt conveyor 14 is installed inside the dewatering section 112 of the housing 11, extending along the direction of the dewatering section 112. The belt conveyor 14 includes a second motor, a belt, a drive roller, and a driven roller. The drive roller and driven roller are rotatably mounted inside the dewatering section 112. The second motor is fixed to the housing 11 and drives the drive roller to rotate. The belt is mounted on the two rollers. A sealing cover 141 can be installed on the outside of the driven roller to prevent water leakage. The driven roller can be positioned close to the water surface, or partially or completely submerged below the water surface. A stirring roller near the belt conveyor 14 will fling feathers onto the belt.
[0050] The lower support plate 17 is installed inside the housing 11 and located below the working section 142 of the belt conveyor 14. The lower support plate 17 is a rectangular plate with downward bent edges on both sides.
[0051] The first dewatering pressure roller 16 is rotatably mounted inside the housing 11, located above the working section 142 of the belt conveyor 14, and cooperates with the lower support plate 17 to squeeze and dewater the feathers on the belt conveyor 14. The dewatering pressure roller includes a roller, and both ends of the roller are connected to a slide rod through bearings. The housing 11 is provided with a slide groove for the slide rod to slide, and the slide groove is set perpendicular to the belt. An adjusting rod is fixed to the housing 11, and the lower end of the adjusting rod is connected to the slide rod. A spring is provided on the adjusting rod, and the spring provides the force for the slide rod to press down on the belt.
[0052] The scraper assembly 15 is located on the upper side of the dewatering section 112 of the box 11 and is attached to the discharge end of the belt conveyor 14 to scrape the feathers on the belt conveyor 14 down to the discharge port.
[0053] In some embodiments, the pre-washing apparatus for hydrolyzed feather powder further includes:
[0054] The rinsing nozzle 18 is located behind the first dewatering roller 16 and faces the dewatered feathers; the rinsing nozzle 18 sprays and rinses the dewatered feathers. The structure of the dewatered feathers is relatively loose, so the rinsing water can penetrate more effectively and remove residual impurities (such as dissolved organic matter, salt, etc.), resulting in a better rinsing effect.
[0055] The second dewatering roller 19 is rotatably mounted inside the housing 11, located above the working section 142 of the belt conveyor 14. It works in conjunction with the lower support plate 17 to squeeze and dewater the wet feathers from the rinsing nozzle 18. The "dewatering-rinsing-re-dewatering" process ensures deep cleaning while minimizing water consumption, thus achieving energy conservation and emission reduction.
[0056] In some embodiments, the pre-washing apparatus for hydrolyzed feather powder further includes:
[0057] Multiple rear nozzles 21 are provided and are located inside the side wall of the feed inlet side of the housing 11. The rear nozzles 21 can form a strong water flow to rinse the feathers from the source of entering the housing 11, thereby improving the initial cleaning efficiency. The rear nozzles 21 also serve as a driving force to push the feathers toward the dewatering section 112.
[0058] The water inlet pipe 22 is located outside the housing 11 and is connected to the rear nozzle 21.
[0059] In some embodiments, the bottom of the housing 11 is provided with a drain outlet 23, and a filter screen is provided inside the drain outlet 23. The drain outlet 23 can be connected to a circulating water tank, or connected to a circulating water tank through a three-way valve. The circulating water tank is connected to the rear spray head 21 through a water pump to achieve recycling. Wastewater can be discharged through the three-way valve or from the circulating water tank. The circulating water tank is located outside the housing 11, and its position can be selected as needed, such as below the dehydration section 112. The attached drawings do not show this.
[0060] The filter screen installed inside the drain outlet 23 can effectively intercept larger impurities in the wastewater (such as feathers and sand).
[0061] In some embodiments, the stirring roller 12 includes:
[0062] The main shaft is rotatably mounted on the housing 11 at both ends;
[0063] The stirring rods are round rods, and multiple rods are arranged at intervals on the main shaft.
[0064] In some embodiments, the scraper assembly 15 includes:
[0065] One end of the arc-shaped plate 151 is attached to the belt conveyor 14;
[0066] The support shaft 152 is connected to the inner side of the arc plate 151, and its two ends pass through the box 11 to the outside.
[0067] Fixing rod 153 is fixed to the outside of the box 11;
[0068] An adjusting plate 154 is connected to the end of the support shaft 152 and has an elongated hole thereon.
[0069] The screw 155 has one end passing through an elongated hole and fixedly connected to the fixing rod 153, and the other end passing through a washer, a spring, and another washer in sequence and connected to a nut. The adjusting plate 154, screw 155, spring, and nut can automatically compensate for minor fluctuations in the belt conveyor 14 or wear of the arc plate 151, maintaining a stable and reliable scraping effect.
