Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, specifically an automatic cleaning device for centrifugal spray drying towers. Background Technology

[0002] In the production process of vitamin D3 powder, centrifugal spray drying towers are usually used for spray drying. The diameter of the centrifugal spray drying tower is usually 3.20 meters and the height is usually 9.50 meters. A steel platform is usually provided in the middle of the tower for personnel to stand and walk during the cleaning operation.

[0003] Centrifugal spray drying towers need to be cleaned after each batch of production. At this time, the operator stands on the steel platform, opens the inspection doors on both sides of the tower wall, and uses a high-pressure water gun to spray the tower wall for rinsing. Each rinsing takes about 8 hours. Not only is the cleaning efficiency low and the labor intensity high, but the cleaning is also not thorough enough. It is impossible to clean under closed conditions, which can easily cause outside air, dust and other contaminants to enter the tower and cause pollution. Utility Model Content

[0004] The purpose of this invention is to overcome the defects and shortcomings of the existing technology and provide an automatic cleaning device for centrifugal spray drying towers. This device can automatically clean the inner wall of the tower body 360° without dead angles and can clean the tower body under closed conditions without introducing new sources of pollution during the cleaning process.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic cleaning device for a centrifugal spray drying tower includes a tower body, a support pipe fixedly connected to the top of the tower body, a hose, and a high-pressure rotary nozzle. The device is characterized in that: a hose winding mechanism is installed on the support pipe; the hose is wound around the hose winding mechanism; one end of the hose is fixed, and the other end extends downward into the interior of the support pipe and is rotatably connected to the high-pressure rotary nozzle; when the hose winding mechanism unwinds, the high-pressure rotary nozzle descends into the interior of the tower body to clean the inner wall of the tower body.

[0007] Furthermore, the hose reeling mechanism includes a bracket, a hose reel, and a drive motor capable of forward and reverse rotation. The bracket is fixedly connected to the top of the supporting pipe, the hose reel is rotatably mounted on the bracket, and the drive motor is mounted on one side of the bracket to drive the hose reel to rotate forward and backward.

[0008] Furthermore, the hose is wound around the hose reel, the fixed end of the hose is fixedly tied to the bracket, and the fixed end of the hose is connected to a water supply pipeline leading to the pump station through a pipe joint for transporting high-pressure cleaning water.

[0009] Furthermore, the extended end of the hose is connected to the high-pressure rotary nozzle via a rotary joint.

[0010] Furthermore, the top of the tower body is provided with a through hole for the high-pressure rotating nozzle to pass through.

[0011] Furthermore, an air inlet is provided on one side of the support pipe and a fan is connected to it.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a hose rewinding mechanism at the top of the centrifugal spray drying tower, with a high-pressure rotary nozzle rotatably connected to one end (not a fixed end) of the hose. When the hose rewinding mechanism unwinds, the high-pressure rotary nozzle is lowered into the tower. Driven by the high-pressure water flow, the nozzle rotates automatically, enabling 360° automatic cleaning of the tower's inner wall without dead angles. This results in a more thorough cleaning, achieving tower cleaning under sealed conditions without introducing new sources of contamination, shortening cleaning time, reducing workload, and saving time and increasing efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figure 1-5 An automatic cleaning device for a centrifugal spray drying tower includes a tower body 1 of a centrifugal spray drying tower, a support pipe 2 fixedly connected to the top of the tower body 1, a hose 3, and a high-pressure rotary nozzle 4. A hose winding mechanism 5 is installed on the support pipe 2. The hose 3 is wound around the hose winding mechanism 5. One end of the hose 3 is a fixed end, and the other end extends downward into the interior of the support pipe 2 and is rotatably connected to the high-pressure rotary nozzle 4. When the hose winding mechanism 5 unwinds, the high-pressure rotary nozzle 4 descends into the interior of the tower body 1 to clean the inner wall of the tower body 1.

[0021] In this utility model, the hose reeling mechanism 5 includes a bracket 51, a hose reel 52, and a drive motor 53 capable of forward and reverse rotation. The bracket 51 is fixedly connected to the top of the supporting pipe 2, the hose reel 52 is rotatably mounted on the bracket 51, and the drive motor 53 is mounted on one side of the bracket 51 to drive the hose reel 52 to perform forward and reverse rotation.

[0022] In this utility model, the hose 3 is wound on the hose reel 52, the fixed end of the hose 3 is fixedly tied to the bracket 51, and the fixed end of the hose 3 is connected to a water supply pipeline (not shown in the figure) leading to the pump station (not shown in the figure) through a pipe joint (not shown in the figure) for transporting high-pressure cleaning water.

[0023] Thus, by driving the tube reel 52 to rotate forward via the drive motor 53, the high-pressure rotary nozzle 4 is lowered from the inside of the support pipe 2 into the inside of the tower body 1. Similarly, by driving the tube reel 52 to rotate in reverse via the drive motor 53, the high-pressure rotary nozzle 4 is raised from the inside of the tower body 1 into the inside of the support pipe 2.

[0024] In addition, the pumping station is equipped with valves, high-pressure pumps and water tanks. The pressure of the high-pressure water can be adjusted by changing the frequency of the high-pressure pump. Furthermore, depending on the difficulty of cleaning, cold water, hot water or alkaline water can be used for cleaning, either alone or in combination.

[0025] In this invention, the extended end of the hose 3 is connected to the high-pressure rotary nozzle 4 via a rotary joint 6, thereby achieving a rotatable connection with the high-pressure rotary nozzle 4.

[0026] In this invention, the top of the tower body 1 is provided with a through hole (not shown in the figure) through which the high-pressure rotating nozzle 4 passes.

[0027] In this utility model, an air inlet 7 is provided on one side of the pipe wall of the support pipe 2 and a fan 8 is connected thereto.

[0028] Therefore, after cleaning, the blower 8 is turned on to blow clean air into the interior of the tower body 1, thereby thoroughly cleaning the excess moisture adhering to the inner wall of the tower body 1.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] During cleaning, the drive motor 53 drives the tube reel 52 to rotate forward and unwind, so that the high-pressure rotating nozzle 4 is lowered from the inside of the support pipe 2 into the inside of the tower body 1.

[0031] Then, the high-pressure pump of the pump station is turned on, and the cleaning water, i.e. high-pressure water, is pumped into the hose 3 through the water supply pipeline. The high-pressure rotating nozzle 4 rotates automatically under the drive of the high-pressure water flow, so as to achieve 360° automatic cleaning of the inner wall of the tower body 1 without dead angles.

[0032] The cleaning time is set according to the cleaning effect, and generally will not exceed 30 minutes.

[0033] After cleaning, the drive motor 53 drives the tube reel 52 to reverse and rewind, so that the high-pressure rotating nozzle 4 rises from the inside of the tower body 1 into the inside of the support pipe 2 without occupying the space inside the tower.

[0034] Then, turn on the fan 8 to blow clean air into the interior of the tower body 1, so as to thoroughly blow away the excess moisture adhering to the inner wall of the tower body 1.

[0035] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0036] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
