Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, specifically to a material storage box cooling system. Background Technology

[0002] In industrial production fields (such as plastics processing, chemical raw material handling, food processing, and pharmaceutical intermediate storage), storage containers, as core equipment for temporary storage and transfer of materials, are widely used in the subsequent processing of high-temperature materials. For example, the discharge temperature of granular materials after plastic extrusion molding, powder raw materials after chemical reactions, and high-temperature dried materials in food processing is usually maintained at 40-120℃. If directly stored in traditional storage containers, problems such as material clumping, deterioration, and performance degradation are likely to occur, which not only affects the accuracy of subsequent processing but may also cause safety hazards due to excessively high temperatures (such as spontaneous combustion of flammable materials and release of volatile raw materials). Therefore, rapid and uniform cooling of high-temperature materials has become a key technical requirement in the design of storage containers. Currently, the cooling methods for storage boxes in the industry mainly have the following shortcomings: Natural cooling is inefficient: Traditional storage boxes without cooling structures rely on environmental heat dissipation, and the cooling cycle is as long as 2-6 hours, which seriously restricts the production cycle and cannot meet the needs of continuous production. The existing cooling structure design is unreasonable: some simple cooling storage boxes use straight water flow channels or single-layer water cooling jackets, which have short water flow paths and limited heat exchange areas, resulting in uneven material cooling (the temperature difference between the middle and the edge of the box can reach 15-25℃). Materials close to the cooling source are prone to over-cooling and clumping, while materials far from the cooling source remain at high temperatures. The contradiction between heat exchange efficiency and equipment lifespan: In order to improve the heat conduction effect, some cooling chambers use metal materials to directly contact the cooling water, but lack targeted anti-rust and heat conduction treatment. After long-term use, the inner wall is prone to rust and scale, which not only reduces the heat conduction efficiency (the thermal conductivity of the rust layer is only 1 / 5-1 / 10 of that of metal), but may also lead to cooling water leakage and contamination of materials. Insufficient functional integration: Existing cooling storage boxes mostly focus only on the cooling function and neglect the supporting design of the discharge process. The discharge pipe is prone to blockage due to material impurities, and the connection between the cooling water and the discharge pipe is not well sealed, often resulting in water leakage, which further affects the purity of the material and the stability of equipment operation. Insufficient water flow disturbance leads to inadequate heat exchange: In traditional water-cooled channels, the water flow is in a laminar state, and the heat exchange with the inner wall of the cooling chamber only occurs at the contact surface. The cooling water in the core area of ​​the water flow cannot fully participate in heat exchange, resulting in wasted cooling energy (under the same cooling effect, the energy consumption is 30%-50% higher than the ideal state). Utility Model Content

[0003] The purpose of this invention is to provide a storage box cooling system to solve the problem mentioned in the background art that traditional storage boxes without cooling structures rely on environmental heat dissipation, with a cooling cycle of up to 2-6 hours, which seriously restricts production cycle and cannot meet the needs of continuous production.

[0004] To achieve the above objectives, this utility model provides a material storage box cooling system, including a material storage box body. A cooling chamber is installed at the bottom of the material storage box body. Several partitions are arranged inside the cooling chamber. A bottom plate is installed at the bottom of the cooling chamber. The partitions are arranged parallel to each other and have a notch at one end. The partitions and the bottom plate form an S-shaped water flow channel inside the cooling chamber. One end of the cooling chamber is connected to an inlet pipe and an outlet pipe. One end of the S-shaped water flow channel is connected to the inlet pipe, and the other end of the S-shaped water flow channel is connected to the outlet pipe.

[0005] This design incorporates a cooling chamber installed at the bottom of the storage box. Inside the cooling chamber, notched partitions are installed parallel to each other, forming an S-shaped water flow channel together with the bottom plate. Cooling water enters the S-shaped channel through the inlet pipe and continuously contacts the inner wall of the cooling chamber (the cooling chamber is in close contact with the bottom of the storage box, and heat is conducted to the cooling chamber). Through heat exchange, the heat of the high-temperature material inside the storage box is carried away, and finally discharged from the outlet pipe, forming a complete cooling flow path.

[0006] Preferably, a discharge pipe is connected to the bottom of one end of the storage box, a through hole is provided on the bottom plate, the lower end of the discharge pipe passes through the through hole, and a sealing ring is provided between the outer wall of the discharge pipe and the inner wall of the through hole.

[0007] This feature involves a discharge pipe extending from the bottom of the storage box through a through-hole in the base plate. A sealing ring fills the gap between the outer wall of the discharge pipe and the inner wall of the through-hole, preventing cooling water from the cooling chamber from seeping into the discharge pipe (contaminating the material) or leaking out of the equipment (damaging parts).

[0008] Preferably, the inlet pipe is connected to a circulating water inlet pipe, and the outlet pipe is connected to a circulating water outlet pipe.

[0009] This setup involves connecting the inlet pipe to an external circulating water inlet pipe (providing low-temperature cooling water) and the outlet pipe to an external circulating water outlet pipe (exporting the heated cooling water to the circulating system, where it is cooled down and then reintroduced into the inlet pipe), forming a closed-loop cooling water circulation.

[0010] Preferably, the surface of the base plate is provided with an outlet and an inlet near the inlet and outlet pipes, one end of the inlet pipe is connected to the inlet and the other end is connected to the cooling chamber, and one end of the outlet pipe is connected to the outlet and the other end is connected to the cooling chamber.

[0011] This design ensures that the water inlet on the base plate surface is precisely connected to the water inlet pipe, guiding the low-temperature cooling water directly into the S-shaped channel inlet; the water outlet is connected to the water outlet pipe, guiding the cooled water after heat absorption to quickly exit the cooling chamber, clearly defining the water flow path in and out of the base plate, and preventing the cooling water from stagnating or forming dead zones in the cooling chamber.

[0012] Preferably, the inner wall of the cooling chamber is coated with a rust-proof and heat-conducting coating, the thickness of which is 0.1-0.3 mm.

[0013] This feature includes a 0.1-0.3mm rust-proof and heat-conducting coating on the inner wall of the cooling chamber. This coating provides thermal conductivity close to that of metal (ensuring efficient heat transfer from the storage box to the cooling water) while also preventing direct contact between the cooling water and the metal inner wall of the cooling chamber, thus preventing corrosion and rust.

[0014] Preferably, the S-shaped water flow channel is provided with several turbulent protrusions, which are evenly distributed on the side wall of the partition and are arranged in an alternating pattern along the water flow direction.

[0015] In this design, the staggered turbulence protrusions on the sidewalls of the baffle in the S-shaped water flow channel break the laminar flow of the cooling water, forcing the water flow to become turbulent, allowing the low-temperature cooling water in the core area of ​​the water flow to fully contact the inner wall of the channel (which carries heat), thereby improving the heat exchange rate.

[0016] Preferably, a manual gate valve is installed on the discharge pipe, and the manual gate valve is located below the base plate.

[0017] This feature includes a manual gate valve installed on the discharge pipe below the base plate. Operators can control the opening and closing of the discharge pipe from outside the cooling chamber (away from the high-temperature storage box) by opening and closing the gate valve, thus achieving precise control of material discharge.

[0018] Preferably, a detachable filter screen is provided at the upper inlet of the discharge pipe, and the filter screen has a pore size of 0.5-2mm.

[0019] This feature includes a 0.5-2mm removable filter screen at the upper inlet of the discharge pipe. This screen filters out impurities and agglomerated particles (with a particle size larger than the filter screen pore size) before the material enters the discharge pipe. The filter screen is also removable for regular cleaning.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: In this material storage box cooling system, the S-shaped water flow channel is the core, which extends the water flow path and expands the heat exchange area, significantly shortening the cooling cycle of high-temperature materials. At the same time, it eliminates local temperature differences, avoids material agglomeration or deterioration, and is suitable for continuous industrial production. In addition, the staggered turbulence protrusions in the channel break the laminar flow state and form turbulence, improving heat exchange efficiency, reducing cooling water circulation volume and cooling energy consumption, and meeting the energy-saving requirements. The rust-proof and heat-conducting coating on the inner wall of the cooling chamber ensures thermal conductivity close to that of metal, preventing efficiency degradation caused by rust, while also isolating the cooling water from contact with the metal to prevent rust and scaling on the inner wall, extending equipment life and preventing material contamination, thus reducing maintenance costs. The discharge process uses a removable filter to prevent clogging and a sealing ring to prevent water leakage, along with an external manual gate valve, to ensure material purity and discharge stability, while also improving operational safety and convenience. Furthermore, the system is designed for water recycling, significantly improving water resource utilization and reducing water costs. The structure of the bottom plate's outlet and inlet ensures smooth, unobstructed water flow, guaranteeing stable heat exchange. In summary, this system, through its "high-efficiency heat exchange + durable protection + functional integration" design, meets the requirements for rapid and uniform cooling, low energy consumption, and long lifespan. It is suitable for high-temperature material storage scenarios in various fields, helping to improve production efficiency and material quality while reducing operating costs.

[0022] 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.

[0023] This utility model provides a cooling system for a storage box, such as Figures 1-4As shown, the device includes a storage box 1, a cooling chamber 2 installed at the bottom of the storage box 1, several partitions 22 are provided inside the cooling chamber 2, and a bottom plate 21 is installed at the bottom of the cooling chamber 2. The partitions 22 are arranged parallel to each other and have a notch at one end. The partitions 22 and the bottom plate 21 form an S-shaped water flow channel inside the cooling chamber 2. One end of the cooling chamber 2 is connected to an inlet pipe 23 and an outlet pipe 24. One end of the S-shaped water flow channel is connected to the inlet pipe 23, and the other end of the S-shaped water flow channel is connected to the outlet pipe 24.

[0024] A cooling chamber 2 is installed at the bottom of the storage box 1. A notched baffle 22 is arranged parallel to the bottom of the cooling chamber 2, forming an S-shaped water flow channel with the baffle 22 and the bottom plate 21. Cooling water enters the S-shaped water flow channel from the inlet pipe 23 and continuously contacts the inner wall of the cooling chamber 2 (the cooling chamber 2 is in contact with the bottom of the storage box 1, and heat is conducted to the cooling chamber 2). Through heat exchange, the heat from the high-temperature material inside the storage box 1 is removed, and the water is finally discharged from the outlet pipe 24, forming a complete cooling flow path. The S-shaped water flow channel formed by the baffle 22 and the bottom plate 21 extends the cooling water flow path and expands the heat exchange area of ​​the inner wall of the cooling chamber 2, solving the problem of "short path and small heat exchange area" in traditional straight-line channels. This significantly improves cooling efficiency (shortening the cooling cycle) and ensures that the cooling water evenly covers the entire cooling chamber 2, preventing the material inside the storage box 1 from clumping or deteriorating due to excessive local temperature differences.

[0025] In this embodiment, a discharge pipe 11 is connected to the bottom of one end of the storage box 1, and a through hole 213 is provided on the bottom plate 21. The lower end of the discharge pipe 11 passes through the through hole 213, and a sealing ring is provided between the outer wall of the discharge pipe 11 and the inner wall of the through hole 213.

[0026] The discharge pipe 11, connected to the bottom of one end of the storage box 1, passes through a through hole 213 on the base plate 21. A sealing ring between the outer wall of the discharge pipe 11 and the inner wall of the through hole 213 fills the gap, preventing cooling water from the cooling chamber 2 from seeping into the discharge pipe 11 (contaminating the material) or leaking out of the equipment (damaging parts). The sealing ring between the discharge pipe 11 and the through hole 213 solves the problem of poor sealing and easy leakage at the discharge point of traditional storage boxes. This ensures the purity of the material in the discharge pipe 11 (especially suitable for the food and pharmaceutical fields) and prevents cooling water leakage from causing corrosion of the base plate 21 or the cooling chamber 2, short circuits in the equipment, and improves the overall operational stability.

[0027] Specifically, the inlet pipe 23 is connected to the external circulating water inlet pipe, and the outlet pipe 24 is connected to the external circulating water outlet pipe.

[0028] The inlet pipe 23 is connected to an external circulating water inlet pipe (providing low-temperature cooling water), and the outlet pipe 24 is connected to an external circulating water outlet pipe (exporting the cooled water that has absorbed heat and risen in temperature to the circulating system, cooling it down, and then re-introducing it into the inlet pipe 23), forming a closed-loop cooling water circulation. This circulating water connection design between the inlet pipe 23 and the outlet pipe 24 replaces the traditional "single-drainage" cooling method, significantly improving water resource utilization, reducing industrial water costs, meeting energy conservation and environmental protection requirements, and avoiding water waste.

[0029] Furthermore, the surface of the base plate 21 is provided with an outlet 211 and an inlet 212 near the inlet pipe 23 and the outlet pipe 24. One end of the inlet pipe 23 is connected to the inlet 212 and the other end is connected to the cooling chamber 2. One end of the outlet pipe 24 is connected to the outlet 211 and the other end is connected to the cooling chamber 2.

[0030] The base plate 21 has an outlet 211 and an inlet 212 located near the inlet pipe 23 and outlet pipe 24. One end of the inlet pipe 23 connects to the inlet 212 and the other end connects to the cooling chamber 2. One end of the outlet pipe 24 connects to the outlet 211 and the other end connects to the cooling chamber 2. This structure clearly defines the inlet and outlet path of the cooling water between the base plate 21 and the cooling chamber 2, preventing the cooling water from stagnating or forming dead zones in the cooling chamber 2. The precise connection between the inlet 212 and the outlet 211 ensures that the cooling water flows smoothly from the inlet pipe 23 to the inlet 212 into the S-shaped water flow channel and from the outlet 211 to the outlet pipe 24, without any local stagnation. This further improves the heat exchange uniformity of the cooling chamber 2 and prevents local cooling failure caused by dead zones in the water flow.

[0031] Furthermore, the inner wall of the cooling chamber 2 is coated with a rust-proof and heat-conducting coating with a thickness of 0.1-0.3 mm.

[0032] The inner wall of cooling chamber 2 is coated with a rust-proof and thermally conductive coating with a thickness of 0.1-0.3mm. This coating has near-metallic thermal conductivity (ensuring efficient heat transfer from storage box 1 to the inner wall of cooling chamber 2, and then to the cooling water), while also preventing direct contact between the cooling water and the metal inner wall of cooling chamber 2, thus preventing corrosion and rust. This rust-proof and thermally conductive coating on the inner wall of cooling chamber 2 solves the problem of the contradiction between heat exchange efficiency and equipment lifespan—maintaining long-term stable thermal conductivity of cooling chamber 2 (avoiding rust layer reducing heat exchange effect), extending the service life of cooling chamber 2, and preventing rust from falling off and contaminating the materials inside storage box 1, thereby reducing the maintenance cost of cooling chamber 2.

[0033] Furthermore, the S-shaped water flow channel is provided with several turbulence protrusions 221, which are evenly distributed on the side wall of the partition 22 and are arranged in an alternating manner along the water flow direction.

[0034] The turbulent flow protrusions 221, evenly distributed on the sidewalls of the baffle 22 and staggered along the water flow direction, within the S-shaped water flow channel, break the laminar flow of the cooling water within the S-shaped channel, forcing the water flow into turbulence. This allows the low-temperature cooling water in the core area to fully contact the inner wall (carrying heat) of the cooling chamber 2, increasing the heat exchange rate. By utilizing the turbulent flow protrusions 221 on the sidewalls of the baffle 22, the problem of insufficient heat exchange in traditional laminar flow is solved, improving the heat exchange efficiency within the cooling chamber 2. Under the same cooling effect, the cooling water circulation volume can be reduced, correspondingly lowering the energy consumption of the cooling process (such as the power of the water pump driving the cooling water flow, and the energy consumption for circulating water preparation).

[0035] Furthermore, a manual gate valve 111 is installed on the discharge pipe 11, and the manual gate valve 111 is located below the base plate 21.

[0036] The manual gate valve 111 installed on the discharge pipe 11 is located below the base plate 21. Operators can control the opening and closing of the discharge pipe 11 from outside the cooling chamber 2 (away from the high-temperature storage box 1) by manually opening and closing the gate valve 111, thus achieving precise control of material discharge from the storage box 1. The manual gate valve 111, located below the base plate 21, improves operational safety (avoiding operator contact with the high-temperature storage box 1) and convenience. It can precisely control the start and stop of discharge from the discharge pipe 11, preventing uncontrolled spillage of material from the storage box 1, and is suitable for batch or intermittent discharge needs.

[0037] Furthermore, a detachable filter screen 112 is provided at the upper inlet of the discharge pipe 11, and the pore size of the filter screen 112 is 0.5-2mm.

[0038] A removable filter screen 112 (pore size 0.5-2mm) is installed at the upper inlet of the discharge pipe 11. Before the material in the storage box 1 enters the discharge pipe 11, it filters out impurities and agglomerated particles (particle size larger than the pore size of the filter screen 112) in the material. The filter screen 112 is removable for regular cleaning. The filter screen 112 at the upper end of the discharge pipe 11 solves the problem of traditional discharge pipes being "easily clogged by impurities", reduces the frequency of clogging of the discharge pipe 11, reduces the maintenance workload of the discharge pipe 11, and prevents impurities from affecting subsequent processing after being discharged with the material through the discharge pipe 11.

[0039] The cooling system for the storage box of this utility model is used in the following steps: Step 1: High-temperature materials are put into storage The high-temperature material to be cooled (such as plastic granules, chemical powders, etc.) is poured into the storage box 1. The material naturally accumulates at the bottom of the box, and at this time the heat of the material begins to be transferred to the cooling chamber 2 through the bottom of the storage box 1. Step 2: Start the cooling system When the external circulating water system is turned on, the low-temperature cooling water flows into the inlet 212 of the bottom plate 21 through the inlet pipe 23, and then enters the S-shaped water flow channel in the cooling chamber 2. When the cooling water flows along the channel, it is guided by the baffle 22 to spread in an "S" shaped path. At the same time, the flow state is disrupted by the turbulence protrusions 221 on the side wall of the baffle 22, forming turbulence. It comes into full contact with the inner wall of the cooling chamber 2 (which has absorbed the heat of the material), quickly absorbs heat and rises in temperature. Step 3: Continuous heat exchange and circulation After absorbing heat and heating up, the cooling water continues to flow along the S-shaped channel and eventually flows into the outlet pipe 24 through the outlet 211 of the bottom plate 21, and is led out to the external circulating water cooling system. The low-temperature cooling water after cooling treatment is input again through the inlet pipe 23, repeating the closed loop of "inlet water - heat absorption - outlet water - cooling", continuously removing the heat of the material in the storage box 1, so that the material temperature is gradually reduced to the target range (such as room temperature or process required temperature). Step 4: Material preparation and operation Once the material has cooled to the acceptable temperature, the operator can discharge the material: First, confirm that there is no excessive accumulation of impurities on the filter screen 112 at the upper end of the discharge pipe 11 (if there are many impurities, the filter screen 112 can be removed, cleaned, and reinstalled); then, manually open the manual gate valve 111 located below the bottom plate 21. The material in the storage box 1 will be smoothly discharged along the discharge pipe 11 after the impurities are filtered by the filter screen 112; after the discharge is completed, close the manual gate valve 111, and the next round of material cooling cycle can begin.
