Description
Technical Field
[0001] The utility model relates to the technical field of finished product material cooling, in particular to a finished product cooling heat energy recovery and utilization device. Background Art
[0002] Many products have a high temperature after being produced in the workshop. Before they are packaged and transported, the finished products need to be cooled to avoid the high temperature from damaging the packaging shell. For example, aluminum fluoride is in a high temperature state when it is produced, and the woven bags used to contain aluminum fluoride often have low high temperature resistance, so the produced aluminum fluoride cannot be directly loaded into the woven bags.
[0003] In order to improve the bagging efficiency of aluminum fluoride, existing manufacturers often set up corresponding circulating cooling equipment to cool the produced aluminum fluoride. Compared with natural cooling in the external environment, this can greatly improve its cooling efficiency, thereby shortening the time from finished product output to packaging and transportation, and improving efficiency.
[0004] However, during the cooling process, the heat of aluminum fluoride will be absorbed by the circulating cooling medium. The circulating cooling medium returns to the refrigeration equipment to cool down and continues to be transported to the aluminum fluoride to absorb heat, thus repeating the cycle. The heat of aluminum fluoride is not effectively utilized, and the refrigeration equipment needs to cool down the higher temperature water, which will also increase the energy consumption of the workshop.
[0005] Therefore, people are in urgent need of a finished product cooling heat energy recovery device with high energy utilization rate and low workshop energy consumption. Summary of the invention
[0006] The purpose of the utility model is to provide a finished product cooling heat energy recovery device to solve the problems existing in the above-mentioned prior art.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] The utility model aims to provide a finished product cooling heat energy recovery and utilization device to solve the problems existing in the prior art. The heat of the finished product is absorbed by the cooler and the heat is transferred to the heat utilization equipment in the workshop, so that the heat energy of the finished product can be effectively utilized.
[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0027] Please refer to Figure 1As shown, a finished product cooling heat energy recovery and utilization device is provided, including a material box 1 and a cooler 2. The material of the outer peripheral wall of the material box 1 is a heat-conducting material such as stainless steel or copper. The specific material is selected according to the finished product to be cooled. A feed port 3 is arranged on the top of the material box 1, and a discharge port 4 is arranged on the bottom, so that the finished product material can move from top to bottom by relying on its own gravity, thereby reducing the energy consumption of supplying the finished product material to move. The outer peripheral wall of the material box 1 is in contact with the cold water channel 5 of the cooler 2, and the outlet of the cold water channel 5 is connected to the heat utilization equipment in the production workshop. The heat utilization equipment is a steam generating equipment or a preheater, etc. When the heat utilization equipment is a steam generating equipment, the water pump of the cooler 2 continuously supplies cold water, and the cold water exchanges heat with the finished product inside the material box 1 through the material box 1, thereby reducing the temperature of the finished product. At the same time, the temperature of the circulating cold water increases, and the material is cooled. The water flowing out of box 1 absorbs the temperature of the finished product and transfers it to the steam generating equipment for use, which is equivalent to supplying preheated water into the steam generating equipment, which can reduce the energy consumption of the steam generating equipment and improve the efficiency of steam generation, thereby making full use of thermal energy and improving energy utilization rate; when the heat utilization equipment is a preheater, the water pump of cooler 2 continuously supplies cold water, and the cold water exchanges heat with the finished product inside box 1 through box 1 and is then transferred to the heat medium channel of the preheater for use, and exchanges heat with the fluid to be preheated. The cooled water after heat exchange flows through the refrigeration equipment and then flows back to the water tank where the water pump is located for circulation. Since the water flow temperature is reduced after passing through the preheater, the refrigeration equipment only needs to cool the lower temperature water to a certain temperature. Compared with cooling higher temperature water, it can effectively save energy consumption.
[0028] In this embodiment, the material box 1 is cylindrical or square-column-shaped with a rectangular cross section, the cooler 2 is a tubular cooler, and the cold water channel 5 of the cooler 2 is arranged in the body of the material box 1 .
[0029] The cold water channel 5 includes a plurality of cooling sections 6, which are cross-interlaced mesh structures or spiral structures and are circumferentially arranged on the inner walls of the material box 1 to increase the contact area between the cold water channel 5 and the material box 1, thereby improving the cooling effect on the internal finished product. The plurality of cooling sections 6 are arranged in the box body of the material box 1 from top to bottom, and adjacent cooling sections 6 are connected by detachable connecting pipes 7. The specific connection method between the connecting pipes 7 and the cooling sections 6 is flange connection; the material box 1 is divided into a plurality of cylinders 8 from top to bottom corresponding to the plurality of cooling sections 6, and adjacent cylinders 8 are connected by flanges. The cold water channel 5 and the material box 1 are designed in sections, so that the overall device can be modularized, and a damaged module can be replaced separately, saving replacement resources, and the module can also be maintained during maintenance, thereby improving the convenience of maintenance.
[0030] In order to improve the cooling effect of the finished materials, the feed amount is set to be greater than the discharge amount, so as to prolong the residence time of the finished materials subsequently entering the material box 1 in the material box 1, or a valve is set at the discharge port 4, and the finished materials are opened to discharge the materials after they stay in the material box 1 for a period of time. The material box 1 is provided with a level meter 9 for detecting the stacking height of the finished products in the material box 1, or an interface for inserting the level meter 9 is provided, so as to obtain the internal material level of the material box 1. When a certain material level is reached, the continued supply of the finished materials can be suspended.
[0031] Since dusty materials will generate dust when being cooled, in order to reduce internal dust, an exhaust port 10 may be provided at the top of the material box 1, and the exhaust port 10 is externally connected to a dust collector to purify the dust.
[0032] The water inlet channel 11 and the water outlet channel 12 of the cooler 2 are both flange-connected to the cold water channel 5, and the feed port 3 is flange-connected to the feed channel 13 for conveying finished materials. The flange connection method can greatly improve the convenience of subsequent disassembly, replacement or maintenance.
[0033] The feed channel 13 in this embodiment can be directly arranged corresponding to the discharge port 4 of the production equipment, so as to directly collect the finished products into the material box 1 .
[0034] In order to facilitate discharge, the discharge port 4 is funnel-shaped, and the small diameter section of the discharge port 4 is arranged away from the material box 1. The bottom of the material box 1 can also be arranged to have a funnel-shaped structure so that the material can slide to the discharge port 4 under its own gravity for discharge.
[0035] During actual use, the finished product enters the material box 1 through the incoming channel and the feed port 3, and exchanges heat and cools down with the cold water in the cold water channel 5 arranged in the box body of the material box 1. The cooled finished product is discharged from the discharge port 4, and can be discharged to the finished product scraper for subsequent transportation. The cold water that absorbs the temperature of the finished product is continuously transported to the heat utilization equipment to utilize the heat absorbed by it.
[0036] Adaptive changes made according to actual needs are all within the protection scope of this utility model.
