Detailed Implementation

[0022] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] The embodiments provided by this utility model are as follows: Figures 1-4 As shown, a spray drying tower includes a main body 10. A feed inlet 20 is located at the center of the top of the main body 10. An air inlet 30 is located at the upper left side of the main body 10. A hot air blower 40 is fixedly installed on the outer side of the main body 10, with its outlet connected to the air inlet 30. A downwardly inclined first inclined plate 50 is fixedly installed on the inner right wall of the main body 10. The lower edge of the first inclined plate 50 is lower than the air inlet 30, and the horizontal length of the first inclined plate 50 is greater than half the horizontal length of the main body 10. An upwardly vibrating motor is fixedly installed at the lower edge of the first inclined plate 50. The first vibrating filter plate 60 has a plurality of first filter holes 70. A downwardly inclined second inclined plate 80 is fixedly installed on the inner wall of the left side of the main body 10. The lower edge of the second inclined plate 80 is lower than the lower edge of the first inclined plate 50. The horizontal length of the second inclined plate 80 is greater than half of the horizontal length of the main body 10. An upwardly inclined second vibrating filter plate 90 with a vibrating motor is fixedly installed at the lower edge of the second inclined plate 80. A plurality of second filter holes 100 are opened on the second vibrating filter plate 90. The diameter of the second filter holes 100 is smaller than the diameter of the first filter holes 70.

[0024] During use, the operator starts the hot air blower 40 and the vibration motors on the first and second vibrating filter plates 60 and 90 via the control center. The hot air blower 40 delivers high-temperature gas into the main body 10 through the air inlet 30 for drying. The dried product particles fall onto the first inclined plate 50 and roll down to the first vibrating filter plate 60. Particles with a diameter larger than the first filter hole 70 are blocked at the first vibrating filter plate 60, while particles with a diameter smaller than the first filter hole 70 pass through the first filter hole 70 and roll down to the second vibrating filter plate 90. The particles are placed on plate 80 and then continue to roll down along the second inclined plate 80 to the second vibrating filter plate 90. Particles with a diameter larger than the second filter hole 100 in the product particles screened by the first vibrating filter plate 60 are blocked at the second vibrating filter plate 90, while product particles with a diameter smaller than the second filter hole 100 pass through the second filter hole 100 and roll down to the bottom of the main body 10. After one round of product drying is completed, the staff turns off the hot air blower 40 and opens the movable door on the front of the main body 10 to manually collect and store the screened product particles in batches in the collection container, thus completing the entire process.

[0025] It should be noted that the vibration motor drives the first vibrating filter plate 60 and the second vibrating filter plate 90 to vibrate continuously. The product particles will also move slightly with the vibration of the vibrating filter plates, so that product particles with a diameter larger than the filter holes will not clog the filter holes, and product particles with a diameter smaller than the filter holes can pass through smoothly.

[0026] Preferably, downward-sloping collection plates 110 are fixedly installed on the inner walls of the left and right sides of the main body 10. The collection plates 110 can guide the dried product particles to the bottom center of the main body 10, making it convenient for staff to collect them.

[0027] Preferably, the bottom of the main body 10 is provided with a discharge port 120, which is located directly below the lower edge of the collecting plate 110. A collecting box 130 is provided on the outside of the main body 10. The collecting box 130 is fixedly connected to the discharge port 120 through a discharge pipe 140. The dried product particles fall into the collecting box 130 along the lower edge of the collecting plate 110, which is convenient for staff to collect.

[0028] Preferably, support columns 150 are fixedly installed at the four corners of the bottom of the main body 10, which facilitates the movement of the drying tower by the staff. The collection box 130 is set below the main body 10, which reduces the floor space occupied by the drying tower.

[0029] Preferably, an air outlet 160 is provided on the side wall of the main body 10, and the air outlet 160 is located below the second inclined plate 80 to ensure that the gas in the drying tower flows fully.

[0030] Preferably, a gas purification box 170 is provided on the outside of the main body 10. The gas purification box 170 is fixedly connected to the gas outlet 160 through the gas outlet pipe 180. An exhaust pipe 190 is fixedly provided on the top of the gas purification box 170. A purification liquid is added inside the gas purification box 170. Harmful gases may be generated during the product drying process. The gas is purified by the gas purification box 170 to protect the production environment.

[0031] Preferably, a first reinforcing plate 200 is horizontally provided at the lower edge of the first inclined plate 50. One end of the first reinforcing plate 200 is fixedly connected to the first inclined plate 50, and the other end is fixedly connected to the right inner wall of the main body 10. The first inclined plate 50, the first reinforcing plate 200 and the right side wall of the main body 10 together form a triangular structure to ensure the stability of the first inclined plate 50 and prevent it from bending after long-term use.

[0032] Preferably, a second reinforcing plate 210 is horizontally provided at the lower edge of the second inclined plate 80, one end of the second reinforcing plate 210 is fixedly connected to the second inclined plate 80, and the other end is fixedly connected to the left inner wall of the main body 10.

[0033] Preferably, a thermometer 220 is fixedly installed inside the main body 10. The thermometer 220 can monitor the temperature environment inside the main body 10, making it convenient for staff to control the temperature of the hot air blower 40.

[0034] Preferably, a first baffle 230 is horizontally fixedly disposed on the top of the first vibrating filter plate 60, and the first baffle 230 is disposed between the first vibrating filter plate 60 and the feed inlet 20. A second baffle 240 is horizontally fixedly disposed on the top of the second vibrating filter plate 90, and the second baffle 240 is disposed between the second vibrating filter plate 90 and the feed inlet 20. The first baffle 230 and the second baffle 240 can effectively prevent product particles from falling over the filter plate due to the vibration of the filter plate, thereby improving the accuracy of the filter plate screening.

[0035] The working principle of this embodiment, and its more specific process, are as follows:

[0036] The staff starts the hot air blower 40 and the vibration motors on the first vibrating filter plate 60 and the second vibrating filter plate 90 through the control center. The hot air blower 40 delivers high-temperature gas to the main body 10 through the air inlet 30 for drying. The dried product particles fall onto the first inclined plate 50 and roll down to the first vibrating filter plate 60. Particles with a diameter larger than the first filter hole 70 are blocked at the first vibrating filter plate 60, while particles with a diameter smaller than the first filter hole 70 pass through the first filter hole 70 and roll down to the second inclined plate 80, and then continue rolling down the second inclined plate 80 to the second vibrating filter plate 90. The product particles with a diameter larger than the first filter hole 70 that have been filtered by the first vibrating filter plate 60 are now considered dry. Particles in the second filter hole 100 are blocked at the second vibrating filter plate 90. Product particles with a diameter smaller than the second filter hole 100 pass through the second filter hole 100 and roll down onto the collection plate 110, and continue to roll down, eventually entering the collection box 130 through the discharge port 120. During the drying process, the operator can adjust the temperature of the gas delivered by the hot air blower 40 according to the temperature value on the thermometer 220 to ensure that the temperature inside the main body 10 is controlled within a reasonable range. The gas inside the main body 10 enters the gas purification box 170 through the air outlet 160 and is finally discharged through the exhaust pipe 190. After one round of product drying is completed, the operator turns off the hot air blower 40 and collects the screened product particles in batches to complete the entire process.

[0037] It should be noted that spray drying towers can be equipped with more inclined plates and filter plates with filter holes of different diameters according to actual usage needs, so as to perform more detailed screening of product particles.

[0038] The spray drying tower of this invention has a downwardly inclined first inclined plate 50 fixedly installed on the inner wall of the right side of the main body 10, and an upwardly inclined first vibrating filter plate 60 fixedly installed at the lower edge of the first inclined plate 50. A downwardly inclined second inclined plate 80 is fixedly installed on the inner wall of the left side of the main body 10, with the lower edge of the second inclined plate 80 lower than the lower edge of the first inclined plate 50. An upwardly inclined second vibrating filter plate 90 is fixedly installed at the lower edge of the second inclined plate 80. This allows the spray drying tower to classify and screen the size of product particles during the product drying process, thereby improving product production efficiency.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
