Abstract
Description
Technical Field
[0001] The present application relates to the field of granulation devices, and in particular to a pressure spray granulator for preparing dispersed granules. Background Art
[0002] Spray granulation is a process where a slurry or solution is sprayed into a granulation tower. The sprayed hot air dries and agglomerates the slurry or solution, resulting in spherical pellets. This method is widely used to produce catalysts of various particle sizes or other particles with specific particle sizes.
[0003] However, conventional spray granulators produce uneven particle size distribution during the preparation process. This is particularly troublesome for applications requiring high particle size accuracy, as subsequent granule classification by size is required. Therefore, a granulator is needed that can simultaneously classify granules by size while granulating them. Utility Model Content
[0004] In order to classify granules according to particle size while completing granulation and improve the discharge effect of the granulator, the present application provides a pressure spray granulator for preparing dispersed granules.
[0005] The present application provides a pressure spray granulator for preparing dispersed granules, which adopts the following technical solution:
[0006] A pressure spray granulator for preparing dispersed granules comprises a spray chamber, a nozzle and a screening assembly; the nozzle is arranged at the top of the spray chamber and is connected to a pressure source; the screening assembly comprises a plurality of screening plates, which are arranged at intervals along the height direction of the spray chamber; the filter holes of the screening plates gradually decrease from high to low in the height direction of the spray chamber; a plurality of discharge ports are opened through the bottom of the spray chamber, which are arranged at intervals along the height direction of the spray chamber, and are used to allow granules to pass through.
[0007] By adopting the above technical solution, during granulation, the liquid material is sprayed out in the form of droplets through the nozzle. The droplets are formed into granules under the action of the hot air device and fall onto the screening plate. They then pass through multiple layers of screening plates with different pore sizes to screen out granules of inconsistent particle sizes. Afterwards, the granules of different particle sizes remaining on each screening plate are removed from each discharge port and collected separately. In this way, the granules are classified according to granule size while granulation is completed, improving the discharge efficiency of the granulator.
[0008] Optionally, a plurality of first elastic ropes are connected to the upper surface of the screen plate near the nozzle, the upper ends of the first elastic ropes are connected to the top of the spray chamber, and the plurality of first elastic ropes are arranged at intervals along the circumference of the screen plate; adjacent screen plates are connected by a plurality of second elastic ropes, and the plurality of second elastic ropes are arranged at intervals along the circumference of the screen plate.
[0009] By adopting the above technical solution, through the connection of the first elastic rope and the second elastic rope, each screening plate has a certain degree of freedom. When the granules fall on the screening plate, under the impact of the granules, the screening plate produces a certain upward and downward movement and rotational movement, that is, the screening plate produces a certain vibration, thereby improving the screening effect of the screening plate.
[0010] Optionally, a plurality of abutment blocks are provided on the peripheral side of the screen plate, and the plurality of abutment blocks are arranged at intervals along the circumference of the screen plate; a plurality of limiting grooves are provided on the inner wall of the spray chamber, and the plurality of abutment blocks are respectively located in the plurality of limiting grooves in a one-to-one correspondence, the length of the limiting groove is greater than the length of the abutment block, and the width of the limiting groove is greater than the width of the abutment block.
[0011] By adopting the above technical solution, the screening plate is limited to a certain extent by utilizing the cooperation between the limiting groove and the abutment block to prevent the first elastic rope and the second elastic rope from being damaged due to excessive deformation, while still ensuring that the screening plate has a certain degree of freedom of movement to ensure the screening effect.
[0012] Optionally, the sieve plate is connected to an annular elastic sheet, the elastic sheet is coaxially arranged with the sieve plate, the outer side of the elastic sheet is connected to the inner wall of the spray chamber, and the limiting groove is located below the elastic sheet.
[0013] By adopting the above technical solution, the elastic sheet is used to block the limiting groove, thereby preventing the granules from falling into the limiting groove and clogging the limiting groove.
[0014] Optionally, a vibration motor is connected to the outside of the spray chamber.
[0015] By adopting the above technical solution, the screening effect of the screening assembly is further improved in combination with the first elastic rope and the second elastic rope.
[0016] In summary, this application includes at least one of the following beneficial technical effects:
[0017] 1. By setting a screening component at the bottom of the spray chamber, granules of different particle sizes are screened, so that the granulator can classify the granules according to the particle size while granulating, thereby improving the output effect of the granulator;
[0018] 2. By setting the first elastic rope, the second elastic rope and the vibration motor, the screening plate is vibrated during the screening process, thereby improving the screening effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is combined with Figure 1-2 This application is described in further detail.
[0023] The embodiment of the present application discloses a pressure spray granulator for preparing dispersed granules.
[0024] Example 1
[0025] Reference Figure 1 and Figure 2 A pressure spray granulator for preparing dispersed granules includes a spray chamber 1, a nozzle 2, a hot air device 3, and a screening assembly 4. The nozzle 2 is installed at the top of the spray chamber 1 and is connected to a pressure source to spray liquid materials into tiny droplets through high-pressure spraying.
[0026] The screening assembly 4 includes a screening plate 41, and multiple screening plates 41 are arranged at intervals along the height direction of the spray chamber 1. In the height direction of the spray chamber 1, the filter holes of the screening plates 41 gradually decrease from high to low. The bottom of the spray chamber 1 is penetrated by multiple discharge ports, and the multiple discharge ports are arranged at intervals along the height direction of the spray chamber 1. The discharge ports are used to allow granules to pass through. During granulation, the liquid material is sprayed out in the form of droplets through the nozzle 2. The droplets are formed into granules under the action of the hot air device 3 and fall onto the screening plate 41. They pass through multiple layers of screening plates 41 with different filter hole sizes to screen granules with inconsistent particle sizes. Afterwards, the granules of different particle sizes remaining on each screening plate 41 are taken out from each discharge port and stored separately. In this way, the granules are classified according to their size while completing the granulation, improving the discharge effect of the granulator.
[0027] Specifically, the screen plate 41 has a circular surface, and the sidewalls of the screen plate 41 are attached to the inner wall of the spray chamber 1. Multiple first elastic cords 42 are connected to the upper surface of the screen plate 41 near the nozzle 2. The upper ends of the first elastic cords 42 are connected to the top of the spray chamber 1. The multiple first elastic cords 42 are arranged at intervals along the circumference of the screen plate 41. Adjacent screen plates 41 are connected by multiple second elastic cords 43. The multiple second elastic cords 43 are arranged at intervals along the circumference of the screen plate 41. The connection between the first elastic cords 42 and the second elastic cords 43 allows each screen plate 41 to have a certain degree of freedom. When granules fall onto the screen plate 41, the impact of the granules causes the screen plate 41 to move up and down and rotate to a certain extent, causing the screen plate 41 to vibrate to a certain extent, thereby improving the screening effect of the screen plate 41.
[0028] Furthermore, the circumferential side of the screening plate 41 is integrally formed with a plurality of abutment blocks 44, and the plurality of abutment blocks 44 are arranged at intervals along the circumference of the screening plate 41. The inner wall of the spray chamber 1 is provided with a plurality of groups of limiting grooves 11, and the limiting grooves 11 are used for inserting the abutment blocks 44. The plurality of groups of limiting grooves 11 are arranged at intervals along the height direction of the spray chamber 1, and the plurality of groups of limiting grooves 11 correspond one-to-one to the plurality of screening plates 41. The plurality of limiting grooves 11 in each group of limiting grooves 11 are arranged at intervals along the circumference of the screening plate 41. The length of the limiting groove 11 is greater than the length of the abutment blocks 44, and the width of the limiting groove 11 is greater than the width of the abutment blocks 44. Thus, by utilizing the cooperation between the limiting grooves 11 and the abutment blocks 44, the screening plate 41 is limited to a certain extent, thereby preventing the first elastic cord 42 and the second elastic cord 43 from being damaged due to excessive deformation, while still ensuring that the screening plate 41 has a certain degree of freedom of movement, thereby ensuring the screening effect.
[0029] It can be understood that in this embodiment, a vibration motor is installed outside the spray chamber 1, and the vibration motor is located at the position of the screening component 4 to cooperate with the first elastic rope 42 and the second elastic rope 43 to further improve the screening effect of the screening component 4.
[0030] Furthermore, an annular elastic sheet 45 is connected to the upper surface of each sieve plate 41. The inner side of the elastic sheet 45 is connected to the sieve plate 41. The elastic sheet 45 and the sieve plate 41 are coaxially arranged. The outer side of the elastic sheet 45 is connected to the inner wall of the spray chamber 1. The limiting groove 11 is located below the elastic sheet 45. The elastic sheet 45 thus blocks the limiting groove 11, preventing granules from falling into the limiting groove 11 and clogging it.
[0031] The implementation principle of Example 1 is as follows: when producing granules, the liquid material is sprayed into the spray chamber 1 at high pressure using the nozzle 2 to form droplets. The liquid is formed into granules under the action of the hot air device 3 and falls onto the screening plate 41; at the same time, the vibration motor is started, and the screening plate 41 is driven to vibrate by the cooperation of the vibration motor, the first elastic rope 42 and the second elastic rope 43. The granules are screened according to the particle size using the screening plates 41 with different filter hole sizes; then the granules on each screening plate 41 can be collected from the position of each discharge port.
[0032] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
