Description

Technical Field

[0001] The utility model relates to the technical field of dry ice machines, in particular to a dry ice machine for preventing ice blockage. Background Technique

[0002] A dry ice machine is a device that uses the physical properties of carbon dioxide (CO2) to generate dry ice. However, during the use of existing dry ice machines, it is found that dry ice often cannot be blown out from the air outlet. After disassembling the corresponding structure, it is found that the direct cause is that a large amount of dry ice blocks the bottom of the funnel-shaped device; the frequency of ice blockage is extremely high, and it needs to be cleaned on average once a day, and each cleaning takes 30 minutes, which affects the on-site production and also increases the workload of maintenance personnel. The reason is that the air contains moisture, and the temperature of dry ice is -79°C, resulting in the generation of condensed water in the working area of the dry ice machine. The condensed water will enter the groove of the shaft along the funnel-shaped device. When employees replace dry ice or in special circumstances, they will briefly turn off the dry ice machine, causing the condensed water to freeze in the groove. If ice blocks form in multiple grooves, dry ice particles cannot be discharged in time, and over time, ice blockage will occur. Therefore, a new dry ice machine for preventing ice blockage is proposed. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1-6 , in the embodiment of the present invention, a dry ice machine for preventing ice blockage includes an ice storage chamber 1 and a bottom plate 2 provided below the ice storage chamber 1. The ice storage chamber 1 and the bottom plate 2 are connected by a base 3. The base 3 includes a fixed plate 3-1 installed on the upper surface of the bottom plate 2. Two vertically arranged support plates 3-2 are parallelly provided on the upper surface of the fixed plate 3-1. A crushing component for crushing the dry ice entering the chamber is provided in the ice storage chamber 1. A gun seat 10 is provided inside the base 3. A feeding hopper 11 connected to the lower surface of the ice storage chamber 1 is provided above the gun seat 10. A driving shaft 4 penetrating through the base 3 is located between the gun seat 10 and the feeding hopper 11. A notch is formed between the gun seat 10 and the feeding hopper 11. Specifically, there is a notch at the place where the rotating area of the shaft is adjacent to the outside. The original purpose of this notch is to discharge the excess dry ice when the cutting amount of dry ice is greater than the ice output amount to avoid ice blockage. However, if the ice blockage is caused by the freezing of condensed water in the shaft groove, it cannot be avoided. A blowing component for blowing air at the notch is provided on the base 3, which is configured to prevent the formation of an ice layer on the driving shaft 4.

[0024] Specifically, the ice storage chamber 1 is funnel-shaped, with openings at both its top and bottom. The inner diameter of the ice storage chamber 1 at the top opening is larger than that at the bottom opening. The feeding hopper 11 is fixedly connected to the bottom of the ice storage chamber 1 to ensure that the dry ice entering the ice storage chamber 1 can smoothly pass through the feeding hopper 11 and be discharged. The middle part of the driving shaft 4 has a plurality of grooves. The crushed dry ice particles will enter the grooves and be blown out along with the rotation of the shaft and the flow of the compressed air pipeline; the blowing component can blow air into the notch all the time when the dry ice machine is working, and the air pressure is above 0.4 MPA, so as to ensure that when condensed water flows into the grooves, it can be cleaned in time, avoiding the freezing of the grooves, thereby solving the problem of ice blockage.

[0025] Please refer to Figure 6, in one embodiment, in this embodiment, preferably, the crushing component includes a crushing blade 9 disposed in the ice storage chamber 1 and a driven shaft 6 horizontally installed in the ice storage chamber 1. The crushing blade 9 is sleeved on the outer peripheral surface of the driven shaft 6, and one end of the driven shaft 6 penetrates to the outside of the ice storage chamber 1. Further, the driven shaft 6 provides a support position for the crushing blade 9 and can also drive the crushing blade 9 to rotate, so as to ensure that the rotating crushing blade 9 can crush the dry ice entering the ice storage chamber 1 and form dry ice particles.

[0026] Please refer to Figure 1 , in one embodiment, in this embodiment, preferably, a driven sprocket 7 is installed at one end of the driven shaft 6, and a driving sprocket 5 is installed at one end of the driving shaft 4. The end of the driving shaft 4 away from the driving sprocket 5 is connected to the motor. The driving sprocket 5 and the driven sprocket 7 are connected by a chain 8. Further, the motor drives the driving shaft 4 to rotate, and the driving shaft 4 drives the driven sprocket 7 to rotate through the driving sprocket 5 at its end and the chain 8. The driven sprocket 7 drives the driven shaft 6 to rotate synchronously during the rotation process, so as to achieve the purpose of driving the crushing blade 9 to rotate.

[0027] Please refer to Figure 3 , in one embodiment, in this embodiment, preferably, a tensioning wheel 13 for controlling the tension of the chain 8 is installed on the surface of the base 3. By adjusting the position of the tensioning wheel 13, the chain 8 is always in a taut state to ensure that the chain 8 is more stable during the transmission process.

[0028] Please refer to Figure 4 , in one embodiment, in this embodiment, preferably, air chambers 12 are installed on the upper surface of the base 3 on both sides of the driving shaft 4.

[0029] Please refer to Figure 2-3 , in one embodiment, in this embodiment, preferably, the blowing component includes a gun head 14 fixed on a gun seat 10. A jet seat 15 that can slide along its length is movably sleeved on the outer peripheral surface of the gun head 14. A jet nozzle 16 for blowing air at the notch is installed on the jet seat 15. The jet nozzle 16 is connected to a temperature sensor. Further, after installing the blowing component, after nearly two months of tracking, no ice blockage phenomenon has occurred, which not only ensures the daily output but also reduces the workload of maintenance. The dry ice machine belongs to standard equipment, and the blowing component is not available in common dry ice machines on the market at present. It is understood that more or less ice blockage phenomena exist in dry ice machines of different brands. Therefore, when designing a dry ice machine, this blowing component can be considered. The cost increases very little, but the effect on solving the ice blockage problem is very obvious.

[0030] Specifically, when the dry ice machine is working, the blowing component will also be turned on simultaneously, sharing part of the compressed air, which will cause insufficient air pressure at the air outlet, thus affecting the processing effect of the product. At the same time, the blowing component being in a working state all the time will also increase the consumption of compressed air. Therefore, on the basis of this solution, through expansion design, it is verified that when the ice is normally discharged from the air outlet, the temperature at this position can reach -20°C or lower, and when the ice is blocked, basically no dry ice is ejected, and the temperature is around 0°C at this time. So a temperature sensor is installed at the air outlet position, and a solenoid valve is used to control the blowing component. The upper limit value of the temperature sensor is set at -5°C, and the lower limit value is set at -20°C. When the temperature rises to -5°C, the temperature sensor sends a signal to the solenoid valve, and the blowing component is turned on. After the ice blockage problem is solved and the ice is normally discharged from the air outlet, the temperature will also drop. When it drops to -20°C, the temperature sensor will send a signal to the solenoid valve again to close the blowing component. In this way, not only the ice blockage problem is solved, the consumption of compressed air is reduced, but also the processing quality of the product is ensured, achieving the purpose of cost reduction and efficiency improvement.

[0031] The working principle and usage process of the present utility model are as follows: By turning on the dry ice machine, the motor drives the rotation of the driving shaft 4, and the driving shaft 4 drives the driven sprocket 7 to rotate through the driving sprocket 5 at its end and the chain 8. During the rotation of the driven sprocket 7, it drives the synchronous rotation of the driven shaft 6, causing the crushing blades 9 located in the ice storage chamber 1 to rotate. Then, dry ice is introduced into the interior of the ice storage chamber 1 and crushed by the crushing blades 9. The crushed dry ice particles will enter the feeding hopper 11. At the bottom of the feeding hopper 11 is the driving shaft 4, and there are multiple grooves in the middle part of the driving shaft 4. The dry ice particles will enter the grooves and flow out along with the rotation of the shaft and the compressed air pipeline, blowing out the dry ice. When the temperature at the air outlet is higher than the set value, the blowing component works to blow air.

[0032] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0033] Therefore, the above is only the preferred embodiment of the present application, and is not used to limit the scope of implementation of the present application; that is, all equivalent transformations made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
