Abstract
Description
Technical Field
[0001] This utility model relates to the field of feed cooling and temperature reduction devices, and in particular to a feed cooling and temperature reduction device. Background Technology
[0002] In the feed production process, feed pellets are at a high temperature after undergoing processes such as pelleting and drying. If they are packaged or stored directly, it will not only affect the quality of the feed, but may also lead to problems such as feed deterioration and mold. Therefore, cooling the feed is an indispensable part of the feed production process, and feed bucket elevator-type air coolers can be used to cool the high-temperature feed after pelleting or extrusion.
[0003] However, when the bucket elevator cooler discharges material, the opening of the discharge bucket itself contracts inward to concentrate the discharge, which causes the feed to easily accumulate near the bottom opening. This is especially true for high-humidity or sticky feed, which can easily cause discharge blockage and affect the continuity of the production line. Therefore, a feed cooling device is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a feed cooling and temperature reduction device, which aims to improve the problem in the prior art that "during discharge, the feed accumulates near the bottom opening due to the inward contraction of the discharge hopper opening, thus affecting the continuity of the production line".
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feed cooling and temperature reduction device, comprising a support frame and a cold air blower body fixedly installed above the support frame. A discharge hopper is provided at the bottom end of the cold air blower body. The discharge hopper is fixedly installed inside the support frame. A discharge assembly is provided on the inner wall of the discharge hopper near the front end. The discharge assembly includes a rotating plate and a servo motor. The servo motor is fixedly installed on the right side of the discharge hopper near the front end. A rotating rod is fixedly connected to the left side of the output shaft of the servo motor. The rotating rod passes through and is rotatably connected to the front inner wall of the discharge hopper. A rotating plate is fixedly connected to the outer wall of the rotating rod inside the discharge hopper, and four sets of rotating plates are arranged in a circular array. Three sets of positioning grooves are respectively opened on the outer side of each rotating plate. Positioning rods are slidably connected to the inner walls of multiple sets of positioning grooves. Multiple sets of positioning rods are elastically connected to the four sets of rotating plates through return springs. Buffer plates are slidably connected to the outer sides of the four sets of rotating plates.

[0007] The multiple sets of buffer plates are all in sliding contact with the inner wall of the discharge hopper, and the multiple sets of positioning rods are respectively fixedly connected to the inner side of the four sets of buffer plates.
[0008] As a further description of the above technical solution:
[0009] All of the aforementioned positioning rods are T-shaped, with the inner diameter being larger than the outer diameter.
[0010] As a further description of the above technical solution:
[0011] The diameter of the multiple positioning grooves is adapted to the inner end diameter of the positioning rod.
[0012] As a further description of the above technical solution:
[0013] A dust suppression component is provided at the top of the discharge hopper. The dust suppression component includes a dust cover, which is fixedly installed at the top of the discharge hopper and wraps the bottom of the air cooler body inside to block dust inside and prevent it from spreading outward. A suction pipe is fixedly installed through the rear surface of the dust cover, and a dust removal fan is fixedly connected to the rear end of the suction pipe.
[0014] As a further description of the above technical solution:

[0016] As a further description of the above technical solution:
[0017] The bottom of the fixed frame is provided with two sets of mounting slots. The inner walls of the two sets of mounting slots are each fitted with a mounting block. The bottom of the four sets of mounting blocks are fixedly connected with a collection frame.
[0018] As a further description of the above technical solution:
[0019] The suction pipes are arranged in three cross-shaped sets, with the front ends of the three sets of suction pipes all connected to the rear surface of the dust cover.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, a servo motor drives four sets of rotating plates in a ring array to rotate continuously, pushing the feed in the discharge hopper outward to ensure that the feed is discharged continuously at a stable flow rate, thereby improving the operating efficiency of the production line. At the same time, the buffer plate on the outside of the rotating plate forms an elastic buffer structure through the positioning rod and the return spring. When encountering feed clumping or foreign object resistance, the buffer plate can contract inward to absorb the impact force, avoiding the interruption of discharge caused by hard jamming, and further enhancing the reliability of the discharge process.
[0022] 2. In this utility model, the bottom of the air cooler is wrapped with a dust cover to form a closed space, preventing dust from spreading into the workshop. Three sets of cross-arranged dust suction pipes work in conjunction with the dust removal fan to form a uniform negative pressure field inside the dust cover, which greatly improves the dust suction efficiency. After the dust-laden airflow enters the collection frame through the dust suction pipe, the dust settles due to gravity caused by the sudden drop in airflow speed. The collection frame supports quick disassembly and cleaning through the plug-in design of the mounting block and the fixing frame, avoiding secondary dust pollution. Dust recycling reduces raw material waste. Attached Figure Description

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a feed cooling and temperature reduction device, comprising a support frame 4 for support and a cooler body 1 fixedly installed above the support frame 4. The cooler body 1 is the main body of a bucket elevator cooler. A discharge hopper 2 for guiding material is provided at the bottom end of the cooler body 1. The discharge position is controlled by the opening direction of the discharge hopper 2. The discharge hopper 2 is designed with a front end and opening that taper inwards. The discharge hopper 2 is fixedly installed inside the support frame 4. The inner wall of the discharge hopper 2 near the front end is provided with a feature to increase discharge efficiency and prevent... The discharge assembly 3 is designed to prevent the feed from piling up. The discharge assembly 3 includes a rotating plate 31 that pushes the feed outward to prevent piling up and a servo motor 32 that drives multiple sets of rotating plates 31 to rotate. The servo motor 32 is fixedly installed on the right side of the discharge hopper 2 near the front end. The output shaft of the servo motor 32 is fixedly connected to a rotating rod 37 that drives multiple sets of rotating plates 31 to rotate. The rotating rod 37 passes through and is rotatably connected to the front inner wall of the discharge hopper 2. The outer wall of the rotating rod 37 is located inside the discharge hopper 2 and is fixedly connected to the rotating plates 31, which are arranged in a circular array of four sets.
[0032] Furthermore, each of the rotating plates 31 has three sets of positioning grooves 34 on its outer side to control the stable movement of the positioning rods 35 and limit the movement distance. The inner walls of the multiple sets of positioning grooves 34 are slidably connected to the positioning rods 35 supporting the buffer plates 33. The multiple sets of positioning rods 35 and the four sets of rotating plates 31 are elastically connected by return springs 36. The elastic force of the return springs 36 can make the buffer plates 33 quickly return to their original position. The outer sides of the four sets of rotating plates 31 are slidably connected to the buffer plates 33 to prevent the feed from being squeezed and getting stuck, thus improving the service life. The multiple sets of buffer plates 33 are slidably in contact with the inner wall of the discharge hopper 2. The multiple sets of positioning rods 35 are fixedly connected to the inner side of the four sets of buffer plates 33. The multiple sets of positioning rods 35 are all T-shaped. The T-shape can limit the movement distance. The inner diameter of the rods is larger than the outer diameter. The diameter of the multiple sets of positioning grooves 34 is adapted to the inner diameter of the positioning rods 35.
[0033] Reference Figure 1 , Figure 2 and Figure 3The top of the discharge hopper 2 is equipped with a dust suppression component 5 to reduce the outward spread of dust from the discharged feed, which could affect the working environment. The dust suppression component 5 includes a dust cover 51 that blocks the dust from the discharged feed. The dust cover 51 is fixedly installed on the top of the discharge hopper 2 and encloses the bottom of the cooler body 1 inside, preventing the dust from spreading outward. A suction pipe 52 is fixedly installed through and on the rear surface of the dust cover 51 to suck up the dust trapped inside. A dust removal fan 55 is fixedly connected to the rear end of the suction pipe 52 to work with it to remove the dust from inside the dust cover 51. The bottom of the machine 55 is fixedly mounted with a support bracket 54. The support bracket 54 is fixedly connected to the rear surface of the bracket 4. The bottom of the support bracket 54 has two sets of mounting slots 56. The inner walls of the two sets of mounting slots 56 are each fitted with a mounting block 57. The mounting block 57 can be inserted into the mounting slot 56 to install the collection frame 53. The bottom of the four sets of mounting blocks 57 is fixedly connected to the collection frame 53 for absorbing and collecting dust. The suction pipes 52 are arranged in three cross directions. The front ends of the three sets of suction pipes 52 are all fixedly connected to the rear surface of the dust cover 51. The three sets of suction pipes 52 arranged in cross directions can improve the dust collection effect.
[0034] Working principle: When in use, first connect the external power supply and switch to the electrical equipment in this device. When the feed cooling device is running, the cooled feed is discharged downward through the cold air blower body 1 to the discharge hopper 2. Due to the inward-sloping design of the front opening of the discharge hopper 2, the feed can be guided to be discharged in a concentrated manner. At this time, the servo motor 32 is started, driving the rotating rod 37 to rotate, which in turn drives the four sets of rotating plates 31 distributed in a ring array to rotate synchronously. During the rotation, the rotating plates 31 continuously push the feed in the discharge hopper 2 outward, effectively preventing the feed from accumulating at the bottom of the discharge hopper 2 and ensuring smooth discharge.
[0035] When the rotating plate 31 encounters significant resistance, such as feed clumping or foreign object obstruction, during the feeding process, the buffer plate 33 slides along the positioning rod 35 in the positioning groove 34 and retracts towards the inside of the rotating plate 31. During this process, the return spring 36 is compressed, absorbing the impact force through elastic deformation to prevent the rotating plate 31 from being damaged due to excessive resistance. When the resistance disappears, the return spring 36 releases its elastic potential energy, pushing the buffer plate 33 to quickly reset, allowing the rotating plate 31 to return to its normal feeding state and improving the discharge efficiency.
[0036] Dust is generated when feed is discharged from hopper 2. Dust is trapped inside the dust cover 51 to prevent it from spreading to the external working environment. The dust cover 51 encloses the bottom of the air cooler body 1, forming a relatively enclosed area to facilitate subsequent dust removal. When the dust removal fan 55 is started, three sets of cross-arranged suction pipes 52 create a negative pressure environment inside the dust cover 51. This cross-arranged suction pipe layout allows for more efficient coverage of the space inside the dust cover 51, improving the dust collection effect. Under the action of the dust cover 51, the dust is sucked into the suction pipe 52 and transported to the collection frame 53 with the airflow. After the dust enters the collection frame 53 with the airflow, due to the sudden drop in airflow speed, the dust settles and accumulates in the collection frame 53 under the action of gravity. The collection frame 53 is connected to the mounting slot 56 on the fixing frame 54 by the mounting block 57, which is convenient for disassembly and cleaning. When the dust in the collection frame 53 reaches a certain amount, it can be removed from the fixing frame 54, the dust can be emptied and reinstalled to ensure the continuous and stable operation of the dust suppression component 5.
[0037] Throughout the entire operation, the support frame 4 provides stable support for components such as the air cooler body 1 and the discharge hopper 2. The components work together to achieve the dual effects of efficient cooling and discharge of feed and a clean working environment.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
