Description

Technical Field

[0001] This invention belongs to the field of biological technology, specifically, it relates to a low-temperature concentration device for long-term continuous automatic ice retrieval. Background Technology

[0002] During the processing of biochemical working fluids, a large amount of material is generated that requires thorough dehydration. Vacuum freeze drying and spray drying are common and energy-intensive facilities for producing powders. For biochemical materials, two types are the most difficult to process: firstly, heat-sensitive biomacromolecules, especially enzyme preparations, which require almost the entire preparation process to be carried out at low temperatures; and secondly, small-molecule biochemical materials, such as amino acids and oligopeptides, which are difficult to process using mechanical means, such as membrane concentration. Moreover, these two types of materials often have relatively low initial concentrations. These substances are usually dehydrated by setting up a pre-concentration device, which can also reduce the workload of subsequent freeze dryers and spray dryers.

[0003] In the existing technology, low-temperature concentration equipment designed based on the principle of extracting fresh water from seawater plays a significant role in the concentration and dehydration of heat-sensitive biomacromolecule raw materials and small molecule biochemical materials. However, the existing equipment is costly, complex to operate, wastes manpower, has an insignificant effect, and affects the concentration efficiency of materials. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A low-temperature concentration device for long-term continuous automatic ice retrieval includes a liquid storage tank assembly and an ice holding tank. The ice holding tank is located at the rear of the liquid storage tank assembly. An electric slide rod is fixedly installed at the upper end of the liquid storage tank assembly. An ice scoop assembly is provided on the sliding end of the electric slide rod. The upper end of the ice scoop assembly is fixedly installed on the liquid storage tank assembly.

A second clearance groove is provided on the side of the sliding plate opposite to the fixed horizontal plate near both ends, and the second clearance groove corresponds to the first clearance groove. The other end of the spring is fixedly installed in the corresponding second clearance groove.

[0014] Further optimization: Multiple ice-removing sleeves are fixedly installed on the end face of the sliding plate away from the fixed horizontal plate. The multiple ice-removing sleeves correspond to multiple sliding rods, and the sliding rods are located inside the corresponding ice-removing sleeves. Ice-removing claws are fixedly installed at the end of the sliding rod away from the sliding plate.

[0015] Further optimization: A liquid level sensor is fixedly installed on the inner wall of the liquid storage tank near the upper end.

[0026] Example 1: As Figure 1-5 As shown: A low-temperature concentration device for long-term continuous automatic ice retrieval includes a liquid storage tank assembly 1 and an ice holding tank 8. The ice holding tank 8 is located at the rear side of the liquid storage tank assembly 1. An electric slide rod 4 is fixedly installed at the upper end of the liquid storage tank assembly 1. An ice scoop assembly 5 is provided on the sliding end of the electric slide rod 4. The upper end of the ice scoop assembly 5 is fixedly installed on the liquid storage tank assembly 1. An ice removal assembly 6 is fixedly installed near the lower part of the mounting surface of the electric slide rod 4. An ice retrieval assembly 7 is also fixedly installed at the sliding end of the electric slide rod 4.

[0027] In this embodiment, the device is placed in a low-temperature cold storage. The heat-sensitive biomacromolecule raw materials and small molecule biochemical materials are concentrated and dehydrated by freezing. That is, by utilizing the difference in melting points between the solvent (such as water) and the solute (such as biomacromolecules), the solvent is frozen into ice crystals at low temperature, while the solute remains in the liquid phase. By slowly melting and removing the ice crystals, the purpose of concentration is achieved. The whole process is carried out in a low-temperature cold storage.

[0028] The liquid storage tank assembly 1 includes a liquid storage tank 12, which holds the solvent to be concentrated.

[0029] A bracket 11 is fixedly installed on the upper surface of the liquid storage tank 12 near one end. The bracket 11 is made of stainless steel pipes and stainless steel plates of different types and is fixedly installed on the liquid storage tank 12 by welding.

[0030] The upper end of the bracket 11 is vertically provided with a mounting plate 3, which extends toward the liquid storage tank 12.

[0031] One end of the electric slide bar 4 is fixedly mounted on the mounting plate 3. A slider 41 is slidably connected to the power output end of the electric slide bar 4. One end of the ice scoop assembly 5 is fixedly mounted on the slider 41 near the upper end.

[0032] The ice-retrieving component 7 is fixedly installed on the slider 41 near the lower end.

[0033] With this design, the slider 41 can slide up and down to drive the ice-holding sieve assembly 5 to open or close.

[0034] like Figure 2 As shown, the ice-holding sieve assembly 5 includes a fixing rod 51 fixedly installed on the mounting vertical plate 3. The fixing rod 51 is installed on another surface of the mounting vertical plate 3 corresponding to the electric sliding rod 4.

[0035] The positions of the fixed rod 51 and the electric slide rod 4 are arranged perpendicular to each other.

[0036] The two ends of the fixed rod 51 are respectively hinged to the first rotating rod 52, and the two first rotating rods 52 are arranged symmetrically.

[0037] The other ends of the two first rotating rods 52 are fixedly connected to L-shaped rods 54, and the two L-shaped rods 54 are arranged symmetrically.

[0038] Two second rotating rods 53 are hinged to the other end of each of the two first rotating rods 52 near the L-shaped rod 54, and the two second rotating rods 53 are arranged symmetrically.

[0039] The other ends of the two second rotating rods 53 are simultaneously hinged to rotating seats 56, which are fixedly installed on the slider 41 near the upper end.

[0040] In this embodiment, the first rotating rod 52 and the fixed rod 51, the first rotating rod 52 and the second rotating rod 53, and the second rotating rod 53 and the rotating seat 56 are all hinged by rotating shafts. The specific connection method is well known and widely used in the prior art, and will not be described in detail here.

[0041] The other ends of the two L-shaped rods 54 are fixedly connected to arc-shaped half-buckets 55. The two arc-shaped half-buckets 55 are arranged symmetrically, forming an ice-holding container.

[0042] like Figure 5 As shown, the bottom surface of the arc-shaped half-hopper 55 is also set as an inclined arc shape, and the bottom surface of the arc-shaped half-hopper 55 is inclined to the ice container 8, that is, the lower end of the ice container is located above the ice container 8.

[0043] The ice container is provided with an ice outlet 57 at its lower end, so that the ice in the ice container enters the ice tank 8 from the ice outlet 57 under the action of the inclined arc.

[0044] With this design, the slider 41 slides up and down, causing the rotating seat 56 to slide up and down. Under the action of the rotating shaft, when the slider 41 slides down, the two second rotating rods 53 rotate on the same straight line, causing the other ends of the two first rotating rods 52 to rotate in a direction away from each other, which in turn causes the two arc-shaped half-bowls 55 to rotate in a direction away from each other, that is, the ice container is in the open state.

[0045] When slider 41 slides upward, it causes the two second rotating rods 53 to rotate at an angle of less than 180°, which in turn causes the other ends of the two first rotating rods 52 to rotate in a direction closer to each other, causing the two arc-shaped half-buckets 55 to rotate in a direction closer to each other, that is, the ice container closes, and after the ice is caught, it slides into the ice container 8 under the action of the inclined arc.

[0046] The de-icing assembly 6 includes a mounting plate 61 fixedly installed at the other end of the mounting surface of the electric slide bar 4.

[0047] Top rods 62 are vertically arranged at both ends of the lower end face of the mounting plate 61.

[0048] With this design, the de-icing component 6 does not slide up and down with the slider 41.

[0049] like Figure 3 As shown, the ice scooping assembly 7 includes a fixed horizontal plate 71 fixedly installed near the lower end of the slider 41, that is, the fixed horizontal plate 71 slides up and down with the slider 41.

[0050] Multiple sliding rods 75 are evenly and vertically arranged on the lower end surface of the fixed horizontal plate 71.

[0051] Multiple sliding rods 75 are slidably connected to the same sliding plate 73 via bearings. The other end of the top rod 62 is located above the sliding plate 73. When the sliding plate 73 slides upward, the other end of the top rod 62 can contact the sliding plate 73.

[0052] The lower end face of the fixed horizontal plate 71 is provided with a first clearance groove near both ends, and a spring 72 is fixedly installed in the first clearance groove.

[0053] The sliding plate 73 and the fixed horizontal plate 71 are provided with second clearance grooves near both ends on the side opposite to each other, and the second clearance grooves correspond to the first clearance grooves.

[0054] The other end of the spring 72 is fixedly installed in the corresponding second clearance groove.

[0055] Multiple ice-removing sleeves 74 are fixedly installed on the end face of the sliding plate 73 away from the fixed horizontal plate 71. The multiple ice-removing sleeves 74 correspond to multiple sliding rods 75, and the sliding rods 75 are located inside the corresponding ice-removing sleeves 74.

[0056] An ice claw 76 is fixedly installed at the end of the slide bar 75 away from the slide plate 73.

[0057] In this embodiment, the ice claw 76 is made of multiple bent steel wires. When the ice claw 76 is in a solvent, ice can be attached to the ice claw 76 over time.

[0058] When the spring 72 is in a naturally compressed state, the ice claw 76 is located outside the ice removal sleeve 74. When the spring 72 is stretched by tension, the ice claw 76 enters the ice removal sleeve 74.

[0059] When the ice-retrieving claw 76 is retrieving ice, the ice-holding container is in the open state, that is, the two second rotating rods 53 are on the same straight line. At this time, the electric sliding rod 4 drives the slider 41 to slide to the lowest end of the electric sliding rod 4, ensuring that the ice-retrieving claw 76 is deeply immersed in the solvent. When the ice-retrieving claw 76 is full of ice and needs to be retrieved, the slider 41 slides upward, driving the rotating seat 56 and the ice-retrieval assembly 7 to slide upward. The ice-holding container closes during the upward sliding process. At this time, since the ice-removing assembly 6 remains stationary, during the upward process of the ice-retrieval assembly 7, the top rod 62 blocks the sliding plate 73 and the ice-removing sleeve 74 from moving upward, while the fixed horizontal plate 71 drives the sliding rod 75 and the ice-retrieving claw 76 to continue to move upward. Then, the ice-removing sleeve 74 removes the ice from the ice-retrieving claw 76, which falls into the ice-holding container and then slides into the ice-holding tank 8.

[0060] A liquid level sensor 120 is fixedly installed on the inner wall of the liquid storage tank 12 near the upper end. The liquid level sensor 120 can detect the liquid level of the liquid storage tank 12, so that the liquid can be replenished at any time.

[0061] A temperature sensor 121 is installed on the inner wall of the liquid storage tank 12 near the liquid level sensor 120. The temperature sensor 121 is used to monitor the temperature inside the liquid storage tank 12 to prevent excessively high temperatures from affecting the freezing rate, and to prevent abnormal temperatures from affecting the activity of solutes in the solvent.

[0062] In this embodiment, both the liquid level sensor 120 and the temperature sensor 121 are commercially available, and their specific detection principles are well known and will not be described in detail here.

[0063] An inlet 122 is provided on the side wall of the liquid storage tank 12 near the lower end, and the inlet 122 is connected to a delivery pipe 123.

[0064] The other end of the infusion tube 123 is connected to the original liquid storage tank 2, which is used to hold the solvent.

[0065] The raw material storage tank 2 is fixedly installed on the inner wall of the cold storage.

[0066] In this embodiment, the outer wall of the raw liquid storage tank 2 is provided with a heat preservation device to prevent the solvent in the raw liquid storage tank 2 from freezing.

[0067] A water valve 125 and a solenoid valve 124 are connected in series on the infusion tube 123. The water valve 125 is located near the original liquid storage tank 2, and the solenoid valve 124 is located near the liquid storage tank 12.

[0068] The solenoid valve 124 can control the solvent to enter the inlet 122.

[0069] The water valve 125 is always open during normal operation. When the device malfunctions, the water valve 125 must be closed to avoid wasting solvent in the original liquid storage tank 2.

[0070] In this embodiment, both the solenoid valve 124 and the water valve 125 are commercially available.

[0071] The control system of the cold storage is also electrically connected to a controller for controlling the low-temperature concentration device that automatically scoops ice, which is not shown in the figure.

[0072] The control terminal of the electric slide bar 4 is electrically connected to the controller, the signal output terminals of the liquid level sensor 120 and the temperature sensor 121 are electrically connected to the controller, and the control terminal of the solenoid valve 124 is electrically connected to the controller.

[0073] The inner walls of the liquid storage tank 12 and the ice container 8 are also equipped with heat preservation devices to ensure that the temperature in the liquid storage tank 12 and the ice container 8 is within acceptable limits. The heat preservation device is electrically connected to the controller. In this embodiment, the working principle of the heat preservation device is well known and can be obtained commercially, so it will not be described in detail here.

[0074] In use, the water valve 125 is manually opened, and the controller controls the opening of the solenoid valve 124. At this time, the solvent in the original liquid storage tank 2 is controlled to enter the storage tank 12 through the inlet pipe 123 and the inlet 122. When the liquid level in the storage tank 12 triggers the liquid level sensor 120, the liquid level sensor 120 feeds the signal back to the controller. The controller controls the closing of the solenoid valve 124 to stop the replenishment of solvent. During the freezing and concentration period, the temperature sensor 121 detects the solvent temperature in real time and feeds the signal back to the controller. The controller controls the heat preservation device on the inner wall of the storage tank 12 according to the preset value to ensure that the temperature in the storage tank 12 is at the working temperature and does not affect the concentration effect.

[0075] The controller controls the start of the electric slide bar 4. The power output end of the electric slide bar 4 drives the slider 41 to slide downward. At the same time, the ice container opens, the fixed horizontal plate 71 moves downward, causing the top rod 62 to disengage from the sliding plate 73, and then the ice claw 76 is exposed. It continues to move downward until the ice claw 76 is immersed in the solvent.

[0076] Then the solvent begins to freeze at low temperature. After a period of time, the ice claw 76 is covered with ice. The controller first controls the start of the electric slide bar 4, which drives the slider 41 to move the fixed horizontal plate 71 upward. At the same time, the rotating seat 56 moves upward to close the ice container. Under the action of the top rod 62, the ice removal sleeve 74 removes the ice from the ice claw 76. The ice blocks fall into the ice container, and the ice removal is completed. The ice in the ice container then slides into the ice tank 8 through the ice outlet 57 for storage.

[0077] During this period, when the liquid level in the storage tank 12 does not reach the level sensor 120, the controller controls the solenoid valve 124 to continue replenishing the liquid, thereby achieving automation. This process is then repeated to complete the concentration of the solute in the solvent and to make ice. The ice in the ice container 8 can be used for other purposes.

[0078] Example 2: The electric slide bar 4 in Example 1 can be replaced by a lead screw and nut to realize the linear movement of the nut on the lead screw. The installation method of the lead screw and nut is well known and will not be described in detail here.

[0079] For those skilled in the art, any changes, modifications, substitutions, and variations made to the embodiments based on the teachings of this utility model, without departing from the principles and spirit of this utility model, still fall within the protection scope of this utility model.
