Abstract
Description
Technical Field
[0001] This utility model relates to the field of feed processing equipment technology, specifically to a pretreatment device for processing feed using citrus pomace. Background Technology
[0002] In the process of processing citrus pomace into feed, it is necessary to pre-mix the citrus pomace with various other materials (i.e., pre-processing of citrus pomace). For example, the citrus pomace fermented feed additive, its preparation method, and its application disclosed in document CN117413886A mixes citrus pomace, tomato seed meal, mulberry leaves, and ginkgo leaves into a pre-fermented mixture. However, when other materials are powdered, the previous processing often presents problems such as inconvenient feeding, high dust levels, and difficulty in achieving uniform mixing. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a pretreatment device for processing citrus pomace into feed.
[0004] This utility model provides the following technical solution: a pretreatment device for processing citrus pomace into feed, comprising a base frame, a support column fixedly installed on the top of the base frame, a top frame fixedly installed on the top of the support column, a twin-shaft continuous mixer fixedly installed on the surface of the base frame, a shaftless screw conveyor installed at the discharge end of the twin-shaft continuous mixer, a material bag installed at the discharge end of the shaftless screw conveyor, two symmetrically arranged screw feeders fixedly installed on the top of the twin-shaft continuous mixer, a shaftless screw feeder installed on the left side of the twin-shaft continuous mixer, and a pulse dust collector fixedly installed on the top of the top frame above the feed hopper of the screw feeders. This specific layout structure ensures at least the uniformity of mixing between the citrus pomace and the two dry powder materials.
[0005] Preferably, a staircase is fixedly installed between the base frame and the top frame.
[0006] Preferably, a guide rail is fixedly installed on the top of the top frame, a slide plate is slidably installed on the top of the guide rail, a crane is fixedly installed on the top of the slide plate, and self-locking components are provided on both sides of the slide plate.
[0007] Preferably, the self-locking assembly includes a housing, which is installed on both sides of the slide plate. A shaft is inserted inside the housing, a plate is fixedly installed on the outside of the shaft, a spring is fitted on the outside of the shaft, a retaining ball is fixedly installed at the bottom of the shaft, and a groove corresponding to the retaining ball is formed on the surface of the guide rail.
[0008] Preferably, the number of slots is several and arranged at equal intervals, and the slide plate is slidably engaged with the guide rail by means of a ball and a slot.
[0009] Compared with the prior art, this utility model has the following advantages: Feed raw materials are lifted and transported by a crane, which moves on a guide rail via a sliding plate. A self-locking component allows for locking the crane in place after movement, making feeding more convenient, reducing manual handling, and improving work efficiency. During the feeding of dry powder materials into the screw feeder, dust is immediately absorbed and treated by a pulse dust collector, reducing dust in the working environment and solving the problem of high dust levels. Subsequently, the dry powder material is introduced into a twin-shaft continuous mixer by the screw feeder. Simultaneously, a shaftless screw conveyor transfers citrus pulp to the twin-shaft continuous mixer, ensuring thorough mixing of the citrus pulp and powder materials and guaranteeing uniform mixing. Finally, the mixture is discharged into a bag or container via a shaftless screw discharger. Attached Figure Description

Detailed Implementation
[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] Please see Figure 1-4 A pretreatment device for processing citrus pomace into feed includes a base frame 1, a support column 2 fixedly installed on the top of the base frame 1, and a top frame 3 fixedly installed on the top of the support column 2.
[0019] Please see Figure 1-4 A twin-shaft continuous mixer 4 is fixedly installed on the surface of the base frame 1 for mixing citrus pomace and two kinds of dry powder materials. A shaftless screw conveyor 5 is provided at the discharge end of the twin-shaft continuous mixer 4 for discharging the mixed material from the citrus pomace and the two kinds of dry powder materials. A material bag 6 or container is provided at the discharge end of the shaftless screw conveyor 5 for storing the mixed material. Two symmetrically arranged screw feeders 7 are fixedly installed on the top of the twin-shaft continuous mixer 4.
[0020] Please see Figure 1-4 A shaftless screw feeder 8 is installed on the left side of the twin-shaft continuous mixer 4 to transfer and feed citrus pomace; a pulse dust collector 9 is fixedly installed on the top of the top frame 3 and above the feed hopper of the screw feeder 7 to adsorb and treat the dust generated during the feeding of the two dry powder materials; a staircase 10 is fixedly installed between the bottom frame 1 and the top frame 3 for personnel to climb onto the top frame 3.
[0021] The discharge ports of the shaftless screw conveyor 8 and the screw feeder 7 are both arranged downwards. The discharge ports of the shaftless screw conveyor 8 and the screw feeder 7 are close to each other (the distance between them is no more than 20cm), and the discharge port of the screw feeder 7 is located downstream of the center of the discharge port of the shaftless screw conveyor 8. This facilitates the directional and uniform feeding of the two dry powder materials and helps to mix the citrus residue and the dry powder materials smoothly.
[0022] Please see Figure 5-6 A guide rail 11 is fixedly installed on the top of the top frame 3. A sliding plate 12 is slidably installed on the top of the guide rail 11. A crane 13 is fixedly installed on the top of the sliding plate 12. Self-locking components 14 are provided on both sides of the sliding plate 12. The crane 13 can move horizontally on the guide rail 11 via the sliding plate 12. After the crane 13 moves to a certain position, it can be locked in place by the self-locking components 14 to prevent the sliding plate 12 from sliding.
[0023] Please see Figure 5-6 The self-locking assembly 14 includes a housing 141, which is installed on both sides of the slide plate 12. A shaft 142 is inserted inside the housing 141. A plate body 143 is fixedly installed on the outside of the shaft 142. A spring 144 is fitted on the outside of the shaft 142.
[0024] Please see Figure 5-6A ball 145 is fixedly installed at the bottom of the shaft 142. The surface of the guide rail 11 is provided with a groove 146 corresponding to the ball 145. There are several grooves 146, which are arranged at equal intervals. The grooves 146 are arranged with arcs between them to facilitate the switching of the position of the ball 145 between the grooves 146. The slide plate 12 is slidably engaged with the guide rail 11 through the ball 145 and the grooves 146.
[0025] During use, the feed raw materials are lifted and transported by the crane 13. The crane 13 moves on the guide rail 11 via the sliding plate 12. The self-locking component 14 can lock the position of the crane 13 after it has moved, making loading more convenient, reducing manual handling, and improving work efficiency. The two dry powder materials are lifted by the crane 13 onto the top frame 3, and then the two dry powder materials are respectively fed into the corresponding screw feeders 7. The dust generated in this process is absorbed and treated by the pulse dust collector 9, reducing dust in the working environment and solving the problem of large dust volume. The dry powder materials are introduced into the twin-shaft continuous mixer 4 by the screw feeder 7 for mixing. At the same time, the citrus pulp is transferred to the twin-shaft continuous mixer 4 by the shaftless screw feeder 8 to achieve full mixing of the citrus pulp and the two powder materials, ensuring the uniformity of the mixing of the citrus pulp and the dry powder materials. Finally, it is discharged into the loading bag 6 or container through the shaftless screw discharger 5.
