Description

Technical Field

[0001] This utility model relates to the field of dry ice machines, and in particular to a discharge device for a dry ice machine. Background Technology

[0002] A dry ice briquetting machine is a specialized piece of equipment used to compress dry ice granules or powder into block-shaped dry ice, playing a crucial role in the dry ice production process. Its working principle is based on powerful mechanical pressure. First, the dry ice raw material, usually dry ice granules obtained through a previous refrigeration process, is conveyed to the feed hopper of the briquetting machine. Subsequently, the raw material is fed into a sealed mold cavity by means of screw propulsion or hydraulic drive. In the mold, enormous pressure is applied to the dry ice raw material, causing the distance between its molecules to decrease drastically, ultimately resulting in a tightly bound block of dry ice with a certain shape and density.

[0003] The prior art, disclosed in CN219483345U, describes a discharge device for a dry ice machine. It includes a main housing with a guide chute extending through both sides and opening upwards. Symmetrically positioned slots are connected between the front and rear walls of the main housing, each containing a heat-insulating plate. Symmetrically positioned working chambers are connected between the front and rear walls of the guide chute. This invention utilizes the inclined guide chute to guide the dry ice downwards. The heat-insulating plate provides insulation, and as the dry ice slides along the surface of the screening plate, smaller particles are filtered through the sieve holes, ensuring efficient output. Furthermore, the invention uses a vibrating plate to generate vibration, which in turn vibrates the screening plate, improving the efficiency of dry ice screening and ultimately increasing the overall production efficiency.

[0004] The above-disclosed technical solution also has the following shortcomings: dry ice blocks collide with each other on the conveyor belt during discharge, which can easily lead to secondary breakage and dust generation. The discharge device cannot effectively remove the dust, resulting in dust generation during discharge, which affects the surrounding environment of the dry ice block discharge and endangers the health of workers. Furthermore, the surface of the broken dry ice blocks produces debris that is not scraped off in time, reducing the overall quality of the dry ice blocks. Utility Model Content

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a discharge device for a dry ice machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a discharge device for a dry ice machine, comprising a dry ice briquetting machine, a top seat, and a feeding plate. The top seat is installed on the upper right side of the dry ice briquetting machine, and the lower end of the top seat is connected to an upper module via a cylinder.

The top plate is located directly below the lower mold. The feeding plate is located on the left side of the dry ice briquetting machine, and a cylinder is connected to the left end of the feeding plate.

[0007] Preferably, the device also includes a cleaning box, the lower end of which is equipped with a conveyor belt. The left side of the conveyor belt is connected to the right side of the dry ice briquetting machine. A support is provided on the outside of the conveyor belt, and a motor is installed on the right end of the support. The output end of the motor drives the conveyor belt for transmission. A vacuum cleaner is also installed on the right end of the cleaning box. The upper end of the vacuum cleaner is connected to a conveying pipe, and the upper end of the conveying pipe is connected to a collection box. The collection box is installed on the top of the cleaning box, and the lower end of the collection box is connected to an adsorption cover. The adsorption cover is installed inside the cleaning box and is located directly above the conveyor belt.

[0008] In a further preferred embodiment, the collection box contains a filter element, and the collection box also contains a thermostat rod, with the thermostat rod located outside the filter element.

[0009] In a further preferred embodiment, a positioning cylinder is provided on the right side inside the collection box, and the right end of the filter element is inserted and installed inside the positioning cylinder. The positioning cylinder is connected through to the upper left side of the conveying pipe. A lower support cover is provided on the left side inside the collection box, and the left end of the filter element is engaged and installed inside the lower support cover. A top cover is installed on the top of the collection box.

[0010] In a further preferred embodiment, a pressing rod is connected to the bottom left side of the top cover, and an upper pressure cover is connected to the lower end of the pressing rod, the upper pressure cover abutting against the upper left end of the filter element.

[0011] In a further preferred embodiment, a miniature vibrator is installed on the outer left side of the collection box, and the miniature vibrator is in contact with the left end face of the upper pressure cover and the lower support cover.

[0012] In a further preferred embodiment, a flow divider is installed inside the adsorption hood.

[0013] In a further preferred embodiment, a cleaning roller is also installed inside the cleaning box. The cleaning roller is located above the conveyor belt. A driven wheel is installed at the left end of the cleaning roller, and a belt is connected to the driven wheel. A drive wheel is installed at the lower end of the belt, and the drive wheel rotates synchronously with the conveyor belt.

[0014] In a further preferred embodiment, a rotating cover is also installed at the right end of the cleaning roller, and a lifting slider is fixed at the center of the outer side of the rotating cover, with a threaded rod passing through the lifting slider and being threadedly connected.

[0015] In a further preferred embodiment, a tensioning mechanism is also installed in the middle of the belt. The tensioning mechanism consists of a tensioning wheel, a guide block, and a spring rod.

The spring rod passes through the guide block with a clearance fit.

[0016] The beneficial effects of this utility model are:

[0017] This invention incorporates a cleaning box. Dry ice dust generated by dry ice blocks being conveyed on a conveyor belt via an adsorption hood is drawn upwards into the collection box. Inside the collection box, the dry ice dust is filtered by a filter element. Simultaneously, a constant temperature rod controls the temperature to prevent dry ice dust from entering the collection box and causing a drop in temperature that could clog the filter element, thus ensuring that the filter element can effectively filter the dry ice dust.

[0018] This invention incorporates a cleaning roller, which, through a conveyor belt, drives the drive wheel to rotate synchronously. Under the transmission of the belt, the driven wheel rotates synchronously, and the rotating threaded rod drives the lifting slider to rise and fall, thereby adjusting the height of the cleaning roller.

Detailed Implementation

[0026] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0027] Please see Figure 1-4 This utility model provides a discharge device for a dry ice machine, including a dry ice briquetting machine 1, a top seat 2, and a feeding plate 3. The top seat 2 is installed on the upper right side of the dry ice briquetting machine 1, and the lower end of the top seat 2 is connected to an upper module 21 via a cylinder. A lower mold 11 is provided on the right side of the dry ice briquetting machine 1, and a top plate 12 is installed inside the right side of the dry ice briquetting machine 1. The top plate 12 is located directly below the lower mold 11. The feeding plate 3 is located on the left side of the dry ice briquetting machine 1, and a cylinder 31 is connected to the left end of the feeding plate 3.

[0028] It also includes a cleaning box 4, with a conveyor belt 41 installed at the lower end of the interior of the cleaning box 4. The left side of the conveyor belt 41 is connected to the right side of the dry ice briquetting machine 1. A support 42 is provided on the outside of the conveyor belt 41, and a motor 43 is installed at the right end of the support 42. The output end of the motor 43 drives the conveyor belt 41 to transmit. A vacuum cleaner 44 is also installed at the right end of the cleaning box 4. A conveying pipe 45 is connected to the upper end of the vacuum cleaner 44. A collection box 46 is connected to the upper end of the conveying pipe 45. The collection box 46 is installed on the top of the cleaning box 4. An adsorption cover 47 is connected to the lower end of the collection box 46. The adsorption cover 47 is installed inside the cleaning box 4 and is located directly above the conveyor belt 41.

[0029] The collection box 46 is equipped with a filter element 461 inside, and a thermostat 4603 is also installed inside the collection box 46, with the thermostat 4603 located outside the filter element 461.

[0030] It should be added that there are three thermostatic rods 4603, located in the front, back, and bottom positions of filter element 461. The thermostatic rod 4603 model is Watlow F4T. The temperature of the thermostatic rod 4603 is controlled within the range of 0-5℃ by a thermostat, ensuring that filter element 461 will not freeze due to low temperature when filtering dry ice dust, thus avoiding clogging of filter element 461 and improving the filtration effect of filter element 461 on dry ice dust.

[0031] A positioning cylinder 4601 is provided on the right side inside the collection box 46, and the right end of the filter element 461 is inserted and installed inside the positioning cylinder 4601. The positioning cylinder 4601 is connected to the upper left side of the conveying pipe 45. A lower support cover 4602 is provided on the left side inside the collection box 46, and the left end of the filter element 461 is engaged and installed inside the lower support cover 4602. A top cover 462 is installed on the top of the collection box 46.

[0032] A pressing rod 463 is connected to the bottom left side of the top cover 462, and an upper pressure cover 464 is connected to the lower end of the pressing rod 463. The upper pressure cover 464 abuts against the upper left end of the filter element 461.

[0033] It should be added that the inner diameter of the positioning cylinder 4601 matches the outer diameter of the right end of the filter element 461, so that the right end of the filter element 461 is stably inserted and fixed inside the positioning cylinder 4601. The pressing rod 463 is composed of two upper and lower round tubes and a pressing rod. Springs are installed inside the upper and lower round tubes, so that the pressing rod 463 has elastic pressing characteristics, which drives the upper pressure cover 464 to press the upper left end of the filter element 461. With the support of the lower support cover 4602, the left end of the filter element 461 is fixed, which facilitates the disassembly and replacement of the filter element 461.

[0034] A miniature vibrator 465 is installed on the left side of the outside of the collection box 46, and the miniature vibrator 465 is in contact with the left end face of the upper pressure cover 464 and the lower support cover 4602;

[0035] It should be added that the micro vibrator 465 is a flat button micro vibration motor. The vibration generated by the micro vibrator 465 is transmitted to the upper pressure cover 464 and the lower support cover 4602, so that the filter element 461 vibrates slightly, which improves the filtration effect of dry ice dust and reduces the clogging of the filter element 461.

[0036] A flow divider 471 is installed inside the adsorption hood 47;

[0037] It should be added that the adsorption hood 47 has a flow guiding structure that is wider at the bottom and narrower at the top, and three flow dividers 471 are provided inside the adsorption hood 47. Under the guidance and diversion of the adsorption hood 47 and the flow dividers 471, the dry ice dust is accelerated to be sucked into the collection box 46, thus preventing the dry ice dust from flowing back.

[0038] Please see Figure 5-6 This utility model provides a discharge device for a dry ice machine. A cleaning roller 48 is installed inside the cleaning box 4. The cleaning roller 48 is located above the conveyor belt 41. A driven wheel 481 is installed at the left end of the cleaning roller 48, and a belt 482 is connected to the driven wheel 481. A drive wheel 483 is installed at the lower end of the belt 482. The drive wheel 483 rotates synchronously with the conveyor belt 41.

[0039] A rotating cover 485 is also installed on the right end of the cleaning roller 48, and a lifting slider 486 is fixed at the center of the outer side of the rotating cover 485. A threaded rod 487 passes through the lifting slider 486 and is threadedly connected.

[0040] It should be added that the rotating cover 485 is equipped with a bearing connected to the right end of the cleaning roller 48, so that the right end of the cleaning roller 48 can rotate inside the rotating cover 485. When the rotating threaded rod 487 drives the lifting slider 486 to rise and fall, the height of the cleaning roller 48 is adjusted to ensure that the cleaning roller 48 can scrape off the debris remaining on the surface of the dry ice block conveyed on the conveyor belt 41. The bearing inside the rotating cover 485 ensures that the rotating cover 485 remains stationary when the cleaning roller 48 rotates.

[0041] A tensioning mechanism 484 is also installed in the middle of the belt 482. The tensioning mechanism 484 consists of a tensioning wheel 4841, a guide block 4842 and a spring rod 4843. The tensioning wheel 4841 is connected to the belt 482 for transmission, and a guide block 4842 is provided at the front end of the tensioning wheel 4841. The spring rod 4843 passes through the guide block 4842 with clearance fit.

[0042] It should be added that there are two tensioning rollers 4841 and two guide blocks 4842. The front end of the tensioning roller 4841 is connected to the guide block 4842 through a bearing cover to ensure that the tensioning roller 4841 does not rotate with the transmission of the belt 482. When the height of the cleaning roller 48 is lowered, the belt 482 becomes loose. At this time, the two guide blocks 4842 are elastically supported by the spring rod 4843, so that the two guide blocks 4842 drive the tensioning roller 4841 to move outward in the opposite direction to adjust and tighten the belt 482. This ensures that the driven roller 481, the belt 482 and the drive roller 483 stably drive the cleaning roller 48 to scrape off the debris remaining on the surface of the dry ice.

[0043] See Figures 1-6When in use, the inside of the feeding plate 3 is filled with raw material particles for preparing dry ice. The feeding plate 3 is pushed above the lower mold 11 of the dry ice briquetting machine 1 by the cylinder 31. At this time, the raw material particles fall into the lower mold 11. Then, the cylinder at the lower end of the top seat 2 pushes the upper module 21 down to press the raw material particles inside the lower mold 11 to form dry ice blocks. Then, the top plate 12 moves up to push the dry ice blocks inside the lower mold 11 upward. Then, the cylinder 31 drives the feeding plate 3 to move above the lower mold 11 again to push the dry ice blocks onto the upper surface of the conveyor belt 41 for discharge.

[0044] When dry ice blocks are transported on conveyor belt 41, they are prone to collisions, generating dry ice dust. At this time, by starting the vacuum cleaner 44, a negative pressure is generated inside the collection box 46 under the conveying pipe 45. The dry ice dust generated by the dry ice blocks being discharged and transported on conveyor belt 41 through the adsorption hood 47 is adsorbed upwards and enters the collection box 46. The dry ice dust enters the collection box 46 and is filtered by the filter element 461. At the same time, the constant temperature control by the constant temperature rod 4603 prevents the dry ice dust from entering the collection box 46 and causing the temperature to drop, which would cause the filter element 461 to become clogged, thus ensuring that the filter element 461 can effectively filter the dry ice dust.

[0045] Furthermore, while processing dry ice dust, the drive wheel 483 is driven to rotate synchronously by the conveyor belt 41, and the driven wheel 481 rotates synchronously under the transmission of the belt 482, which drives the cleaning roller 48 to rotate and scrape off the debris remaining on the surface of the dry ice block, thereby improving the overall quality of the dry ice block.

[0046] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
