Description

Technical Field

[0001] This utility model relates to a liquefaction spraying device, and in particular to a starch liquefaction spraying device for starch sugar processing, belonging to the field of starch sugar processing technology. Background Technology

[0002] The starch liquefaction jetting device for starch sugar processing is a key piece of equipment used to convert starch slurry into liquid syrup through a liquefaction process. In the starch sugar production process, the starch liquefaction jetting device uses high temperature and pressure to break up and dissolve the starch particles in the starch slurry, and then converts it into syrup through a liquefaction reaction.

[0003] CN214262394U discloses a starch liquefaction spraying device for starch sugar processing, including a mixing chamber. An air inlet pipe is connected to the upper side of the mixing chamber, a feed pipe is connected to one side of the mixing chamber, and a spraying pipe is connected to the lower side of the mixing chamber. An air chamber is provided on the inner wall of the mixing chamber corresponding to the lower end of the air inlet pipe, and the air chamber is connected to the internal cavity of the mixing chamber through an air inlet. A material chamber is provided on the inner wall of the mixing chamber corresponding to the end of the feed pipe, and the material chamber is connected to the internal cavity of the mixing chamber through a feed inlet. A flow channel is provided on the upper side of the spraying pipe, and a ball chamber is provided along the flow channel path. In this starch liquefaction spraying device, the mixing chamber contains an air chamber and a material chamber. The air chamber disperses steam into the mixing chamber, and the material chamber disperses the material into the mixing chamber. These components work together to increase the mixing rate of steam and material, thereby increasing the liquefaction spraying quality. The ball chamber on the flow channel inside the spraying pipe further increases the mixing uniformity before spraying.

[0004] However, during actual operation, the starch solution may contain some large, undissolved precipitates. Since the device does not have an interception mechanism, these large precipitates may be sprayed out directly after mixing with steam, forming uneven syrup, which may affect the processing of starch sugar or cause waste of raw materials. This needs to be improved.

[0005] Therefore, a starch liquefaction spraying device for starch sugar processing is proposed. Utility Model Content

[0028] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figure 1-8 As shown, this utility model embodiment provides a starch liquefaction spraying device for starch sugar processing, including a mixing chamber 1 and an interception chamber 8. The mixing chamber 1 is connected to a spraying pipe 4 through a quick-connect mechanism. A filter plate 9 is installed inside the interception chamber 8. A motor 10 is installed at the top of the interception chamber 8. A threaded rod 11 is installed at the output end of the motor 10. A cleaning plate 12 is slidably installed on the inner wall of the interception chamber 8. A through groove 13 is provided on the bottom surface of the interception chamber 8. A discharge pipe 14 is provided at the bottom of the through groove 13. A baffle 16 is slidably installed inside the interception chamber 8. A receiving groove 15 adapted to the baffle 16 is provided inside the through groove 13. A gear 17 is installed at the bottom of the threaded rod 11. A toothed plate 18 that meshes with the gear 17 is installed on the baffle 16.

[0031] In one embodiment, the quick-release mechanism includes a connecting block 19, a grooved tube 20, a threaded sleeve 21, an annular plate 23, and a sealing ring 24. The connecting block 19 is installed above the injection pipe 4, the grooved tube 20 is connected below the mixing chamber 1, the threaded sleeve 21 is disposed on the grooved tube 20, the annular plate 23 is installed on the injection pipe 4, and the sealing ring 24 is disposed on the annular plate 23. The quick-release mechanism allows for rapid disassembly and reassembly between the injection pipe 4 and the mixing chamber 1, enabling the injection pipe 4 to be quickly removed for cleaning and maintenance of its inner wall after the injection operation is completed.

[0032] In one embodiment, a steam pipe 2 is connected to the mixing chamber 1, and a steam valve 3 is installed on the steam pipe 2. A feeding pipe 5 is connected to the side of the mixing chamber 1, and a feeding valve 6 is installed on the feeding pipe 5. A feeding pump 7 is connected to the side of the feeding pipe 5, with the feeding end of the feeding pump 7 connected to the feeding pipe 5 and the suction end of the feeding pump 7 connected to the interception chamber 8. Steam enters the mixing chamber 1 through the steam pipe 2, and the feeding pipe 5 rapidly extracts the slurry under the action of the feeding pump 7.

[0033] In one embodiment, the cleaning plate 12 is vertically attached to the filter plate 9, and the discharge pipe 14 communicates with the interior of the interception cavity 8 through the through groove 13. As the cleaning plate 12 slides along the inner wall of the interception cavity 8, it scrapes off the intercepted material on the surface of the filter plate 9 in the process.

[0034] In one embodiment, the cleaning plate 12 is provided with threads, and the cleaning plate 12 is connected to the threaded rod 11 by threads. When the motor 10 is started and the threaded rod 11 is driven to rotate, the cleaning plate 12 can be driven to slide from top to bottom along the inner wall of the interception cavity 8 under the action of the threads.

[0035] In one embodiment, the inner side of the groove tube 20 is provided with a slot adapted to the connecting block 19, and a lever 22 is installed on the threaded sleeve 21. The connection and installation between the groove tube 20 and the connecting block 19 can be carried out quickly, and the lever 22 facilitates the rotation of the threaded sleeve 21 without the need for tools.

[0036] In one embodiment, the groove tube 20 is provided with threads, and the groove tube 20 and the threaded sleeve 21 are connected by threads. Rotating the actuating rod 22 causes the threaded sleeve 21 to rotate, and under the action of the threads, the threaded sleeve 21 moves up and down along the groove tube 20.

[0037] In operation, this invention works as follows: First, the steam valve 3 and the feeding valve 6 are opened. Then, steam enters the mixing chamber 1 through the steam pipe 2. At the same time, the slurry is rapidly extracted by the feeding pump 7. The starch liquid first passes through the interception chamber 8. During the process of passing through the filter plate 9, the starch liquid passes through the filter gaps of the filter plate 9 and enters the mixing chamber 1 along the feeding pipe 5. Then, the large starch particles that are not completely dissolved in the starch liquid are intercepted by the filter plate 9. Next, the starch liquid comes into contact with and mixes with the high-pressure steam in the mixing chamber 1. Finally, it is liquefied and sprayed out through the spray pipe 4. When it is necessary to clean the filter plate 9, the motor 10 is started and the threaded rod 11 is driven to rotate. Under the action of the thread, the cleaning plate 12 is driven to slide from top to bottom along the inner wall of the interception chamber 8, and the intercepted objects on the surface of the filter plate 9 are scraped off during this process. At the same time, the rotation of the threaded rod 11 drives the gear 17 below to rotate. Under the meshing action between the gear 17 and the toothed plate 18, the baffle 1 is driven to rotate. 6. The filter plate 9 is stored along the receiving groove 15, and the through groove 13 is opened. At this time, as the intercepted objects on the surface of the filter plate 9 are scraped off, they will fall into the discharge pipe 14 below under the action of gravity, thus completing the cleaning work of the filter plate 9. When the motor 10 drives the threaded rod 11 to reverse, the cleaning plate 12 will slide upward under the action of the thread, and the baffle 16 will close again under the action of the gear 17 and the toothed plate 18, blocking the through groove 13. When disassembling the spray pipe 4, first turn the lever 22 and drive the threaded rod 13. The sleeve 21 rotates and, under the action of the thread, drives the threaded sleeve 21 to move upward along the groove tube 20, and no longer abuts against the connection between the groove tube 20 and the connecting block 19. Then, the spray pipe 4 and the connecting block 19 can be pulled out together along the groove tube 20. During installation, first slide the spray pipe 4 and the connecting block 19 into the groove on the surface of the groove tube 20, then rotate the lever 22 in the opposite direction and drive the threaded sleeve 21 downward along the groove tube 20, finally abutting against the connecting block 19 and pressing the sealing ring 24 against the ring plate 23.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
