Description

Technical Field

[0001] The utility model relates to the field of fermented feed processing, in particular to a cooling device for fermented feed processing. Background Art

[0002] During the process of wine lees drying, the dehydrated wine lees are transported through the conveying equipment into the drying kiln for drying. The temperature of the dried wine lees is high, which is not conducive to the transportation and subsequent processing of the wine lees. Therefore, the wine lees need to be cooled for subsequent use.

[0003] In view of this, a Feng Shui energy system for biological organic feed processing with patent application number CN202122250990.2 is applied, which performs water cooling and air cooling respectively by setting a circulating cooling water pipeline at the bottom of the spiral conveyor and setting a fan at the top. However, in actual use, due to the large spiral conveyor, the circulating cold water pipeline required is long, and in the process of S-shaped arrangement, the cooling water in the tail section undergoes heat exchange, and its temperature is even higher than the temperature of the feed to be discharged, so its cooling effect in the tail section is not good. At the same time, when using a fan for cooling, due to the large air outlet, the air flow speed is small, the cold air only contacts the surface of the wine lees for a short time, the cooling rate is low, and the gas of the wine lees escapes from the fan, resulting in a strong smell of wine lees on site. Utility Model Content

[0004] The utility model aims to provide a cooling device for fermented feed processing, which can provide a better cooling effect of distiller's grains feed and reduce the escape of distiller's grains smell.

[0029] First embodiment

[0030] See also Figure 1-4 The present embodiment provides a cooling device for fermented feed processing, comprising a screw conveyor 100, a water cooling jacket 200 disposed at the bottom of the screw conveyor 100, and an air cooling assembly 300 disposed at the top of the screw conveyor 100. The air cooling assembly 200 and the water cooling jacket 200 can be reinforced on the screw conveyor 100 by a clamp.

[0031] The screw conveyor 100 is provided with a feed port at the top of the front end, a discharge port at the bottom of the rear end, and an air outlet at the top of the rear end for connecting to an exhaust gas treatment system.

[0032] This embodiment makes an improvement on the water-cooling jacket 200, which includes a jacket body 210, which is a metal jacket with a C-shaped cross section cut along the axial direction. The high thermal conductivity coating is applied to the inner and outer layers of the bottom of the shell of the screw conveyor 100 to improve the thermal conductivity of the screw conveyor 100, so as to better exchange heat with the water-cooling jacket 200.

[0033] The interior of the jacket body 210 is divided into a plurality of independent cooling channel units 230 by a partition plate 220. A water inlet 240 and a water outlet 250 are respectively arranged on the horizontal planes of both sides of each cooling channel unit 230, and the water inlet 240 and the water outlet 250 are connected to a water cooling circulation assembly 260, so that a single independent cooling channel unit 230 can independently control the water temperature and liquid flow rate.

[0034] Specifically, the interior of the cooling channel unit 230 includes a vertical water inlet channel 231, an arc water blocking channel 232, and two semi-arc water blocking channels 233 arranged on both sides of the arc water blocking channel 232, and the middle of the arc water blocking channel 232 is directly opposite to the water outlet end of the vertical water inlet channel 231. In this embodiment, by arranging the arc water blocking channel 232 and the semi-arc water blocking channel 233 in the channel, the water flow can have a certain distance of reflux after passing through the arc water blocking channel 232 and the semi-arc water blocking channel 233, extending the travel path of the water flow, and staying at the bottom of the screw conveyor 100 with a higher temperature for a longer time, so that the water flow can fully perform contact heat exchange and improve the heat exchange efficiency.

[0035] The water cooling circulation assembly 260 includes an inlet pipeline 261, a chiller 262, a circulating water pump 263, and an outlet pipeline 264 connected in sequence. The outlet pipeline 264 is connected to the water inlet 240, and the inlet pipeline 261 is connected to the drain outlet 250. Each cooling channel unit 230 can be provided with a separate circulating water pump 263 to control the water flow rate of the separate cooling channel unit 230; the corresponding number of inlet pipelines 261 and outlet pipelines 264 is matched with the cooling channel unit 230, and the chiller 262 is provided with one, which is a small industrial chiller, and the rapid cooling temperature can be reduced to 3°C. The intelligent control can control the water temperature. It is placed under the frame of the screw conveyor 100, and the circulating water pump 263 is external to the chiller 262.

[0036] The chiller 262 uses HS1500-LAS1-001A chiller 262, which can perform circulating refrigeration and has low cost of use.

[0037] This embodiment also improves the air cooling assembly 300, and a plurality of air cooling assemblies 300 arranged in a linear array are provided on the top of the screw conveyor 100. The air cooling assembly 300 includes an air jet base 310 and an air pressure pump 320. The cross section of the air jet base 310 is arc-shaped and welded to the screw conveyor 100. The corresponding assembly position is first cut on the screw conveyor 100, and then the assembled air jet base 310 is welded and fixed to the screw conveyor 100.

[0038] Among them, the top of the jet base 310 is provided with an air inlet 311, and the air inlet 311 is equipped with a solenoid valve 312. The interior of the jet base 310 is provided with a jet flow channel 313, and the tail of each jet flow channel 313 is provided with a jet hole, and each jet hole position is provided with a jet nozzle 314. In this embodiment, the assembly position radius of the jet nozzle 314 of the jet base 310 is larger than the inner diameter of the screw conveyor 100. After assembly, it is ensured that the port of the jet nozzle 314 coincides with the inner diameter of the screw conveyor 100, so as to prevent the spiral blade of the screw conveyor 100 from touching the jet nozzle 314. The jet nozzle 314 is arranged at equal distances along the inner diameter circumference. The air pressure pump 320 is connected to each air inlet 311 through an air pipe, so that the compressed gas can smoothly enter each jet nozzle 314 for cooling. The air pressure pump 320 uses an Otus silent oil-free air compressor, and the four-cylinder compression is fast.

[0039] In this embodiment, a temperature and humidity sensor 315 is also provided on the jet base 310. The temperature and humidity sensor 315 is provided in the middle or lower part of the inner wall of the screw conveyor 100. The temperature and humidity sensor 315 is a patch sensor.

[0040] The cooling device also includes a control terminal 400 connected to the temperature and humidity sensor 315, which is used to transmit the temperature of each section of the screw conveyor 100 collected by the temperature and humidity sensor 315 to the control terminal 400. The control terminal 400 determines to accelerate or reduce the temperature of each section according to the threshold of each section temperature. The control terminal 400 is respectively connected to the circulating water pump 263, the solenoid valve 312 and the air pressure pump 320. The chiller 262 continuously cools water, and the cooling water in the chiller 262 is drawn into the corresponding pipe section by controlling the circulating water pump 263, thereby controlling the water inlet and outlet speeds, thereby controlling the cooling speed.

[0041] At the same time, the control terminal 400 is also connected to the solenoid valve 312 and the air pressure pump 320, which compares the threshold temperature with the acquired real-time temperature. Therefore, when accelerated cooling is required, the air pressure pump 320 is started for a long time, and the solenoid valve 312 of the corresponding pipe section is started, so as to perform long-term cold air injection to accelerate cooling; when, for example, the temperature at the tail end is already within the threshold range, the solenoid valve 312 of the section is closed, or opened intermittently, so as to reduce the amount of cold air injection.

[0042] In summary, the advantages of the improved cooling device for fermented feed processing are:

[0043] 1. By improving the water-cooling jacket 200, the original S-shaped circulating cold water pipeline is changed to a C-shaped jacket with multiple cooling channel units 230, so that cold water can enter each pipe section at the bottom of the screw conveyor 100 respectively, thereby ensuring that the temperature of each pipe section is low, thereby improving the cooling effect of the lees;

[0044] 2. Design the flow channel in the cooling flow channel unit 230 to ensure that the cooling water can fully exchange heat with the outer wall of the screw conveyor 100, so that the lees can be cooled as quickly as possible during the conveying process;

[0045] 3. The air cooling component 300 is designed to be an air cooling structure for jetting air, so that the compressed air quickly impacts the lees, thereby quickly removing the temperature of the lees;

[0046] 4. The spiral conveyor 100 is designed to be cooled in sections through a water-cooling jacket 200 and a plurality of air-cooling components 300, and the temperature of each section is collected through a control terminal 400. When the temperature of the section is within the interval, the cold air injection and water cooling operations are performed normally; when the temperature of the section is high, the cold air injection speed is increased, and the water cooling transmission speed of the section is increased, thereby increasing the cooling speed of the section; when the temperature of the section is reduced, the cold air injection speed is reduced, or changed to intermittent injection, and the water flow rate is reduced, so that the wine lees can be stably cooled during the transmission process.
