Description

Technical Field

[0001] This invention relates to the field of drying tower cleaning technology, specifically to an insertable drying tower cleaning device. Background Technology

[0002] Spray drying towers are common equipment used for rapid and continuous drying of wet materials. They have advantages such as continuous production, fast drying speed, convenient operation and control, and suitability for large-scale production. However, when drying raw material liquid, the liquid usually remains on the inner wall of the spray drying tower. In order not to affect the next use, people usually pour clean water into the tower and use cleaning tools to clean the inner wall of the drying tower back and forth. This is laborious, and since the drying tower is relatively large, it takes a long time and the cleaning efficiency is low. A solution is needed to solve the above-mentioned technical problems.

[0003] As described in the patent document with publication number CN219073819U, this device, by setting up a hydraulic rod, a rotating wheel and a cleaning shaft, and a cleaning component, can achieve stable up-and-down movement and rotation of the cleaning component through their mutual cooperation during use, so that the cleaning component can continuously scrub the inner wall of the spray drying tower, thereby improving the cleaning efficiency and effect.

[0004] Because the inner wall of the drying tower has an inclined surface, the above-mentioned device has cleaning dead corners when cleaning the drying tower, making it difficult to effectively clean the inner wall of the drying tower and affecting the subsequent production of powder. At the same time, when collecting powder through the cyclone separator, the raw material liquid will adhere to the inner wall of the collection pipe connected to the cyclone separator, which can easily cause blockage of the collection pipe. Summary of the Invention

[0005] The technical problem that this solution addresses is:

[0006] (1) How to solve the problem that the inner wall of the drying tower has a sloping surface, which creates dead corners for cleaning and makes it difficult to effectively clean the inner wall of the drying tower, thus affecting the subsequent powder production;

[0007] (2) How to solve the problem that the raw material liquid will adhere to the inner wall of the collection pipe connected to the cyclone separator, which will easily cause the collection pipe to be blocked.

[0008] The objective of this invention can be achieved through the following technical solution: an immersion drying tower cleaning device, comprising a drying tower body, a cleaning mechanism for removing the raw material liquid inside the drying tower body is provided at the top of the drying tower body, and a collecting mechanism for collecting powder is provided on one side of the bottom of the drying tower body, and a first atomizing nozzle for spraying raw material liquid is provided inside the drying tower body, and a raw material pipe is fixedly connected to the bottom of the first atomizing nozzle, and the input end of the raw material pipe extends out of the drying tower body.

[0009] The cleaning mechanism includes an adjusting pipe that is movably inserted into the top of the drying tower body. The adjusting pipe is a square tube, and two electric heating plates are symmetrically arranged on both sides of the inner wall of the adjusting pipe. Both electric heating plates are embedded in the middle of the adjusting pipe. Spray holes are opened on the four sides of the bottom of the adjusting pipe, and a second atomizing nozzle is provided inside each spray hole.

[0010] A further technical improvement of the present invention is that: a longitudinally arranged cylinder is fixedly connected to the top of the drying tower body by a mounting bracket; the extended end of the cylinder movably passes through the regulating pipe and is fixedly connected to a first piston; the first piston is slidably connected to the inner wall of the regulating pipe; and sufficient cleaning agent is placed on the top of the first piston; the top of the first piston and the top of the inner wall of the regulating pipe are elastically connected by a tension spring; and sufficient clean water is stored in the regulating pipe below the first piston.

[0011] A further technical improvement of the present invention is as follows: Several nozzles are fixedly embedded on all four sides of the middle portion of the regulating pipe. The output ends of the nozzles do not extend beyond the outer wall of the regulating pipe, and a one-way valve is fixedly installed in the middle of each nozzle. The opening direction of the one-way valve is the same as the direction in which the clean water in the regulating pipe is discharged into the drying tower body. A limiting ring is fixedly fitted on the top side wall of the regulating pipe, and a water inlet pipe is fixedly inserted into the top of the regulating pipe. A water inlet control valve is fixedly installed in the middle of the water inlet pipe, and the input end of the water inlet pipe is connected to an external water supply device via a flexible hose. After collecting the powder, two electric heating plates are turned on to heat the clean water in the regulating pipe. The temperature of the clean water is monitored by an external temperature detection device. When the water temperature reaches 80 degrees Celsius, the cylinder is then controlled to extend. When the cylinder extends to its longest length, after the limiting ring contacts the drying tower body, the first piston slides downward relative to the regulating pipe, squeezing the water inside the regulating pipe and spraying it out through the four second atomizing nozzles. This heats and melts the raw material liquid on the inner wall of the drying tower body, facilitating subsequent cleaning. When the cylinder's extended end is at its longest length, the first piston contacts the bottom of the inner wall of the regulating pipe, and the first piston is located below the electric heating plate. During the downward sliding of the first piston relative to the regulating pipe, the water inlet control valve is opened, allowing clean water to be injected into the regulating pipe at the top of the first piston. This water mixes with the cleaning agent to form a cleaning solution. Simultaneously, because the first piston is located below the electric heating plate, the electric heating plate continuously heats the cleaning solution, improving the cleaning efficiency of the sprayed cleaning solution on the raw material liquid on the inner wall of the drying tower body.

[0012] A further technical improvement of the present invention is that a sealing ring is provided at the connection between the drying tower body and the regulating pipe, and the position of the sealing ring corresponds to the position of the spray hole.

[0013] A further technical improvement of the present invention is that: the collecting mechanism includes a cyclone separator fixedly connected to the drying tower body, the cyclone separator is prior art, and the input end of the cyclone separator is connected to a longitudinally arranged second collecting pipe, and a transversely arranged first collecting pipe is fixedly inserted into the bottom of the drying tower body, the middle part of the first collecting pipe is connected to the input end of the second collecting pipe.

[0014] A further technical improvement of the present invention is that: a horizontally arranged electric push rod is fixedly installed on the top of the cyclone separator by a fixing frame, the protruding end of the electric push rod extends into the first receiving pipe, and a second piston is fixedly installed and slidably connected to the inner wall of the first receiving pipe; after collecting the powder, by controlling the protruding end of the electric push rod to extend, the second piston slides in the first receiving pipe, scraping off the dry raw material liquid attached to its inner wall, avoiding blockage of the first receiving pipe, and preventing interference with the normal operation of the cyclone separator.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In use, after collecting the powder, two electric heating plates are turned on to heat the water in the regulating pipe. The temperature of the water is monitored by an external temperature detection device. When the water temperature reaches 80 degrees Celsius, the cylinder is extended to its maximum length. After the limiting ring contacts the drying tower body, the first piston slides downward relative to the regulating pipe, squeezing the water in the regulating pipe and spraying it out through four second atomizing nozzles. This heats and melts the raw material liquid on the inner wall of the drying tower body, facilitating subsequent cleaning. When the cylinder is at its maximum length, the first piston contacts the bottom of the inner wall of the regulating pipe and is located below the electric heating plate. During the downward sliding of the first piston relative to the regulating pipe, the water inlet control valve is opened, allowing water to be injected into the regulating pipe at the top of the first piston. This water mixes with the cleaning agent to form a cleaning solution. Simultaneously, because the first piston is located below the electric heating plate, the electric heating plate continuously heats the cleaning solution, improving the cleaning efficiency of the sprayed cleaning solution on the raw material liquid on the inner wall of the drying tower body.

[0017] In use, after collecting the powder, the extension end of the electric push rod is controlled to extend, causing the second piston to slide inside the first receiving tube, scraping off the dry raw material liquid adhering to its inner wall, thus preventing it from clogging the first receiving tube and interfering with the normal operation of the cyclone separator.

[0025] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-5 As shown, an extended drying tower cleaning device includes a drying tower body 3. A cleaning mechanism 1 for removing the raw material liquid inside the drying tower body 3 is provided at the top of the drying tower body 3, and a collecting mechanism 6 for collecting powder is provided on one side of the bottom of the drying tower body 3. A first atomizing nozzle 7 for spraying raw material liquid is provided inside the drying tower body 3. A raw material pipe 4 is fixedly connected to the bottom of the first atomizing nozzle 7, and the input end of the raw material pipe 4 extends out of the drying tower body 3.

[0027] Please see Figures 1-4 As shown, the cleaning mechanism 1 includes an adjusting pipe 105 that is movably inserted into the top of the drying tower body 3. The adjusting pipe 105 is a square tube, and two electric heating plates 107 are symmetrically arranged on both sides of the inner wall of the adjusting pipe 105. Both electric heating plates 107 are embedded in the middle of the adjusting pipe 105. Spray holes 104 are opened on the four sides of the bottom of the adjusting pipe 105, and a second atomizing nozzle is provided inside the spray holes 104.

[0028] Please see Figure 2 and Figure 3As shown, the top of the drying tower body 3 is fixedly connected to a longitudinally arranged cylinder 101 via a mounting bracket 8. The extended end of the cylinder 101 extends through the regulating pipe 105 and is fixedly connected to a first piston 106. The first piston 106 is slidably connected to the inner wall of the regulating pipe 105, and a sufficient amount of cleaning agent is placed on the top of the first piston 106. The top of the first piston 106 and the top of the inner wall of the regulating pipe 105 are elastically connected by a tension spring. A sufficient amount of clean water is stored in the regulating pipe 105 below the first piston 106.

[0029] Please see Figure 3 and Figure 4 As shown, several nozzles 108 are fixedly embedded on the four sides of the middle part of the regulating pipe 105. The output end of the nozzle 108 does not extend out of the outer wall of the regulating pipe 105, and a one-way valve is fixedly installed in the middle of the nozzle 108. The opening direction of the one-way valve is the same as the direction in which the clean water in the regulating pipe 105 is discharged into the drying tower body 3. A limiting ring 109 is fixedly sleeved on the top side wall of the regulating pipe 105, and a water inlet pipe 103 is also fixedly inserted into the top of the regulating pipe 105. A water inlet control valve is fixedly installed in the middle of the water inlet pipe 103, and the input end of the water inlet pipe 103 is connected to the external water supply equipment through a hose 102. After the powder is collected, two electric heating plates 107 are turned on to heat the clean water in the regulating pipe 105. The temperature of the clean water is monitored by an external temperature detection device. When the temperature of the clean water reaches 80 degrees, the extension end of the cylinder 101 is controlled to extend to its maximum length and then the limit is reached. After the ring 109 contacts the drying tower body 3, the first piston 106 slides downward relative to the regulating pipe 105, squeezing the clean water in the regulating pipe 105 and spraying it out through the four second atomizing nozzles to heat and melt the raw material liquid on the inner wall of the drying tower body 3, facilitating subsequent cleaning. When the extended end of the cylinder 101 is at its longest, the first piston 106 contacts the bottom of the inner wall of the regulating pipe 105, and the first piston 106 is located below the electric heating plate 107. During the downward sliding of the first piston 106 relative to the regulating pipe 105, the water inlet control valve is opened, allowing clean water to be injected into the regulating pipe 105 at the top of the first piston 106, mixing with the cleaning agent to form a cleaning liquid. At the same time, since the first piston 106 is located below the electric heating plate 107, the electric heating plate 107 continuously heats the cleaning liquid, improving the cleaning efficiency of the sprayed cleaning liquid on the inner wall of the drying tower body 3.

[0030] Please see Figure 2 As shown, a sealing ring 9 is provided at the connection between the drying tower body 3 and the regulating pipe 105, and the position of the sealing ring 9 corresponds to the position of the spray hole 104.

[0031] Please see Figure 1 and Figure 5As shown, the above-mentioned collecting mechanism 6 includes a cyclone separator 603 fixedly connected to the drying tower body 3. The cyclone separator 603 is the prior art, and the input end of the cyclone separator 603 is connected to a longitudinally arranged second collecting pipe 602. The bottom of the drying tower body 3 is fixedly inserted with a transversely arranged first collecting pipe 601, and the middle part of the first collecting pipe 601 is connected to the input end of the second collecting pipe 602.

[0032] Please see Figure 5 As shown, the top of the cyclone separator 603 is fixedly mounted with a horizontally arranged electric push rod 605 by a fixing bracket. The protruding end of the electric push rod 605 extends into the first receiving pipe 601, and a second piston 604 is fixedly mounted and slidably connected to the inner wall of the first receiving pipe 601. After collecting the powder, by controlling the extension of the protruding end of the electric push rod 605, the second piston 604 slides in the first receiving pipe 601 to scrape off the dry raw material liquid adhering to its inner wall, so as to avoid clogging the first receiving pipe 601 and prevent interference with the normal operation of the cyclone separator 603.

[0033] Please see Figure 1 As shown, a hot air pipe 2 for conveying hot air flow is fixedly connected to one side of the top of the drying tower body 3, and a drain pipe 5 is also connected to the bottom of the drying tower body 3, with a drain valve fixedly installed in the middle of the drain pipe 5.

[0034] Working principle: In use, the invention firstly sprays atomized raw material liquid through the raw material pipe 4 in conjunction with the first atomizing nozzle 7. At this time, the extended end of the electric push rod 605 is at its shortest, and the second piston 604 is located at the end of the first receiving pipe 601 away from the drying tower body 3. The water inlet control valve and the sewage discharge control valve are closed, and the cyclone separator 603 is turned on to collect the dried powder. Hot air is then transported into the drying tower body 3 through the hot air pipe 2 to ensure the subsequent drying efficiency of the raw material liquid. After collecting the powder, the two electric heating plates 107 are turned on and switched. The water inside the regulating pipe 105 is heated, and its temperature is monitored by an external temperature detection device. When the water temperature reaches 80 degrees Celsius, the extended end of the cylinder 101 is extended to its maximum length. After the limiting ring 109 contacts the drying tower body 3, the first piston 106 slides downward relative to the regulating pipe 105, squeezing the water inside the regulating pipe 105 and spraying it out through four second atomizing nozzles. This heats and melts the raw material liquid on the inner wall of the drying tower body 3, facilitating subsequent cleaning. When the extended end of the cylinder 101 is at its maximum length, the first piston... The plug 106 contacts the bottom of the inner wall of the regulating pipe 105, and the first piston 106 is located below the electric heating plate 107. During the downward sliding of the first piston 106 relative to the regulating pipe 105, the water inlet control valve is opened, allowing clean water to be injected into the regulating pipe 105 at the top of the first piston 106, mixing with the cleaning agent to form a cleaning solution. Simultaneously, because the first piston 106 is located below the electric heating plate 107, the electric heating plate 107 continuously heats the cleaning solution, improving the cleaning effect of the sprayed cleaning solution on the raw material liquid on the inner wall of the drying tower body 3. Efficiency; After collecting the powder, the extension end of the electric push rod 605 is extended, causing the second piston 604 to slide inside the first receiving pipe 601, scraping off the dry raw material liquid adhering to its inner wall, preventing it from clogging the first receiving pipe 601 and preventing interference with the normal operation of the cyclone separator 603; When the extension end of the electric push rod 605 is at its longest, the second piston 604 is located at the opening of the first receiving pipe 601, opening the drain control valve, and flushing out the raw material liquid inside the drying tower body 3 through sprayed atomized clean water and cleaning liquid.
