Description

Technical Field

[0001] This utility model belongs to the technical field of ice-lowering devices, and more specifically, relates to an ice-lowering device. Background Technology

[0002] In some chemical production processes, ice makers are used to produce small ice flakes to ensure that the reaction is carried out at low temperatures. These small ice flakes are collected and stored in a collection box, and then blown into the reaction vessel by a blower, thereby achieving automatic ice addition and stable temperature control during the reaction process.

[0003] However, the existing pipes that transport ice blocks do not have a device to separate the ice blocks from the air when they are blown into the reactor. As a result, the air blowing the ice blocks is also brought into the reactor. When the reactor needs to expel the air that has entered along with the ice blocks, it causes other gases in the reactor to be mixed and discharged together, polluting the environment. Utility Model Content

[0004] This invention provides an ice-releasing device that can separate ice blocks blown into a reaction vessel from air, thereby improving environmental protection.

[0005] This utility model discloses an ice-feeding device, comprising: an air supply module for providing low-temperature airflow; an ice conveying module connected to the air supply module for conveying ice blocks; a cyclone separator including an inlet, an exhaust outlet, and a discharge outlet; the inlet is connected to the ice conveying module and is tangentially arranged around the outer wall of the cyclone separator to receive airflow containing ice blocks; the exhaust outlet is located at the top of the cyclone separator for discharging air; the discharge outlet is located at the bottom of the cyclone separator, its diameter being smaller than the central cavity of the cyclone separator, and its inner wall slopes to form a conical discharge channel; and a reaction vessel connected to the cyclone separator through the discharge outlet.

[0006] As a further improvement of this utility model, the air supply module includes a fan and an air cooler connected in sequence, and a silencer is provided at the output end of the fan.

[0007] As a further improvement of this utility model, the ice conveying module includes an ice conveying cylinder and a storage refrigerator. One end of the ice conveying cylinder is connected to the air supply module, and the other end is connected to the feed inlet of the cyclone separator. The storage refrigerator and the ice conveying cylinder are interconnected. A valve is provided between the storage refrigerator and the ice conveying cylinder to control the opening and closing of the ice conveying channel.

[0008] As a further improvement of this utility model, the discharge port of the cyclone separator is equipped with a knife valve to control the opening and closing of the discharge channel.

[0009] As a further improvement of this utility model, a feed pipe is provided at the top of the reactor, and the discharge port is connected to the feed pipe through a knife valve.

[0010] As a further improvement of this utility model, the diameter of the exhaust port is smaller than that of the central cavity of the cyclone separator.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By designing a cyclone separator with its inlet, outlet, and discharge port, an air mixture containing ice enters the upper cylinder of the cyclone separator at high speed tangentially. The airflow is forced into a high-speed spiral rotation within the cylinder. This rotating airflow generates a strong centrifugal force. Since ice is much denser than air, it is subjected to this strong centrifugal force and thrown against the cylinder wall. Driven by gravity and the downward airflow, it slides down the wall and concentrates at the bottom of the cyclone separator. The outer swirling airflow at the bottom of the cone, constrained by the space at the bottom and driven by the low pressure at the center, reverses direction to form an inner swirling flow upwards, thus separating the ice from the airflow. The air is then discharged through the central exhaust port at the top. Meanwhile, the ice falls into the reaction vessel through the inclined channel of the discharge port, achieving cooling within the reaction vessel and significantly improving environmental protection.

[0018] Specific Implementation Example 1: Please refer to... Figures 1-3 An ice-feeding device includes a fan 1, an air cooler 2, an ice conveying cylinder 3, a cyclone separator 4, and a reaction vessel 5 connected in sequence, and all of the above devices are interconnected by pipelines.

[0019] Specifically, the upper end of the fan 1 is provided with an air inlet duct to draw in outside air and deliver it into the duct. The output end of the fan 1 is provided with a silencer 11, and the silencer 11 is detachably connected to the fan 1 to reduce the noise of the fan 1 during operation.

[0020] Specifically, the air cooler 2 includes at least a tube bundle, a tube box, a frame, an axial fan, and louvers. The tube bundle is the core heat transfer element of the air cooler 2, containing a flowing cooling medium. The tube box connects the tube bundle and distributes the medium. The frame provides overall support; the axial fan forces airflow to enhance heat dissipation; and the louvers are used to regulate airflow or prevent freezing. The air cooler 2 is used to cool the air delivered by the fan 1 and blow it towards the ice delivery cylinder 3 to prevent the higher air temperature from melting the ice delivered inside the ice delivery cylinder 3.

[0021] Specifically, the ice conveying cylinder 3 is equipped with at least a three-way connector, with its first port connected to the air cooler 2 and its second port connected to the cyclone separator 4. A storage refrigerator 31 is also installed on the outside of the ice conveying cylinder 3, and its third port is connected to the storage refrigerator 31. A valve 311 is installed between the ice conveying cylinder 3 and the storage refrigerator 31 to control the ice conveying operation of the storage refrigerator 31 towards the ice conveying cylinder 3.

[0022] Specifically, the cyclone separator 4 is installed at the upper end of the reactor 5. The cyclone separator 4 includes a feed inlet 41, an exhaust outlet 42, a discharge outlet 43, and a knife valve 44. One end of the feed inlet 41 is connected to the ice conveying cylinder 3 via a pipe. The exhaust outlet 42 is located at the upper end of the cyclone separator 4, and the discharge outlet 43 is located at the lower end of the cyclone separator 4. The feed inlet 41 is tangentially arranged around the outer wall of the cyclone separator 4 so that the ice and air entering the cyclone separator 4 from the feed inlet 41 enter tangentially against the inner wall. The inner cavity of the cyclone separator 4 is hollow, and the diameter of one end of the exhaust outlet 42 is smaller than that of the central hollow cavity of the cyclone separator 4, and the diameter of one end of the discharge outlet 43 is smaller than that of the central hollow cavity of the cyclone separator 4. The discharge outlet 43 transitions smoothly and obliquely to the inner wall of the central hollow cavity of the cyclone separator 4, so that the lower end of the cyclone separator 4 forms a cone shape. A knife valve 44 is installed at the lower end of the discharge port 43. The knife valve 44 is used to control the opening or closing of the discharge port 43 into the reaction vessel 5 channel. Under normal circumstances, the exhaust port 42 is connected to the outside.

[0023] Specifically, a feed pipe 51 is provided on one side of the upper end of the reactor 5, and the discharge port 43 is connected to the feed pipe 51. The discharge port 43 and the feed pipe 51 are controlled to open or close by a knife valve 44.

[0024] It should be noted that during ice conveying, the air-ice mixture enters the upper cylinder of the cyclone separator 4 at high speed tangentially. The airflow is forced into a high-speed spiral motion within the cylinder (the outer spiral flows downward). The rotating airflow generates a strong centrifugal force. Since the ice is much denser than air, it is subjected to this strong centrifugal force and thrown against the cylinder wall of the cyclone separator 4. Driven by gravity and the downward airflow, it slides down the cylinder wall and concentrates at the bottom of the cyclone separator 4. The outer spiral airflow at the bottom of the cone, constrained by the space at the bottom and driven by the low pressure at the center, reverses to form an inner spiral flowing upward, thus separating the ice from the airflow. The air (inner spiral) is then discharged through the central exhaust port 42 at the top. When cooling is required inside the reactor 5, the knife valve 44 is opened to allow the ice to fall into the reactor 5, while simultaneously preventing gas from flowing out of the reactor 5 and quickly closing the knife valve.

[0025] Working principle:

[0026] Fan 1 draws in outside air, which is then cooled by silencer 11 and delivered to air cooler 2 to form a low-temperature airflow. This low-temperature airflow enters ice conveying cylinder 3 and mixes with ice blocks in storage refrigerator 31, controlled by valve 311, to form an ice-containing airflow. This ice-containing airflow enters the cavity of cyclone separator 4 tangentially through the inlet 41, forming a high-speed rotating airflow. The ice blocks are carried to the bottom of cyclone separator 4, where the airflow, constrained by the conical bottom space and driven by the central low pressure, reverses direction, forming an internal vortex that flows upwards and exits through the central exhaust port 42 at the top. Meanwhile, the ice blocks fall along the inclined inner wall of discharge port 43 due to gravity, and after being controlled by knife valve 44, enter reaction vessel 5 through feed pipe 51, achieving gas-ice separation.
