[0002] During the current spray drying process in the workshop, a lot of powder adheres to the inner wall of the tower. Even the vibration of the air hammer cannot remove it. The long-term adhesion of the material to the wall affects the production quality and efficiency. At the same time, the operators need to manually clean the material on the inner wall, which increases a lot of repetitive work.

[0003] In the prior art, such as the patent with publication number CN215691700U, a spray drying device for processing pharmaceutical excipients is disclosed, including a support frame, a spray drying unit fixedly installed on the top of the support frame, a main tower fixedly installed on the top of the support frame near the surface of the spray drying unit, a slot opened on the surface of the main tower near the bottom, a baffle slidably connected to the inner wall of the slot, a spray head installed on the inner wall of the main tower, and an upper cleaning assembly provided inside the main tower.

[0004] The method of cleaning the inner wall mentioned in the above patent is too cumbersome. Too many components can reduce the internal space of the dryer, making operation inconvenient and reducing production efficiency. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide a device for cleaning materials adhering to the walls inside a spray dryer tower, which can effectively solve the problems mentioned in the background art.

[0006] The present invention adopts the following technical solution: a device for cleaning materials adhering to the inner wall of a spray dryer tower, comprising a spray tower body with a wide upper part and a narrow lower part, an inverted conical container structure, an atomizer penetrating the top of the spray tower body, and a discharge port at the bottom. A scraper is vertically arranged on the inner wall of the spray tower body, and a positioning plate is fixedly installed on the top of the inner wall of the spray tower body. A fixing ring is coaxially fixedly connected to the discharge port. The positioning end of the upper part of the scraper is movably connected to the positioning plate, and the lower part of the scraper is movably connected to the fixing ring.

[0007] The inner wall of the fixed ring is provided with a first slide rail along the circumference. The lower end of the scraper is provided with a sliding component 1 that is tangent to the inner wall of the fixed ring. The sliding component 1 is provided with a first slider for circumferential relative movement within the first slide rail.

[0008] A second slide rail is provided on the bottom surface of the fixed ring along the circumferential direction. A second sliding member is fixedly provided at the lower end of the sliding member, and a second slider is provided on the second sliding member for circumferential relative movement within the second slide rail.

[0009] The feature is that: the positioning plate is provided with a circular positioning slide rail on the side facing the inner wall of the spray tower, and the upper positioning end of the scraper is provided with a positioning slider for making circular motion in the positioning slide rail.

[0010] A drive source is fixedly installed on the bottom surface of the sliding component, and the drive source is a manually operated handle.

[0011] A drive source, which is a motor drive, is fixedly installed on the bottom surface of the sliding component.

[0012] Compared with the prior art, the advantages of this utility model are: this device uses a scraper that fits against the inner wall of the spray tower to clean the powder adhering to the inner wall. The three sets of slider track mechanisms limit the movement direction of the scraper, which reduces the space occupied inside the spray tower and greatly improves production efficiency.

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0016] Please see Figure 1 , Figure 2 , Figure 3As shown, a device for cleaning materials adhering to the walls inside a spray dryer tower includes a spray tower 1 with a wide upper section and a narrow lower section, forming an inverted conical container structure. The top of the spray tower 1 is equipped with an atomizer 13 that penetrates the tower body, and the bottom is provided with a discharge port 11. The inner wall of the spray tower 1 is vertically provided with a scraper 2 that fits against its inner wall. A positioning plate 12 is fixedly installed at the top of the inner wall of the spray tower 1. A fixing ring 14 is coaxially fixedly connected to the discharge port 11. The positioning end 22 at the upper end of the scraper 2 is movably connected to the positioning plate 12, and the lower end of the scraper 2 is movably connected to the fixing ring 14.

[0017] The positioning plate 12 is bolted to the spray tower body 1, and the fixing ring 14 is bolted to the discharge port 11. The scraper 2 can be disassembled for cleaning when cleaning is required.

[0018] The inner wall of the fixed ring 14 is provided with a first slide rail 141 along the circumference. The lower end of the scraper 2 is provided with a sliding member 23 that is tangent to the inner wall of the fixed ring 14. The sliding member 23 is provided with a first slider 231 for circumferential movement within the first slide rail 141.

[0019] The bottom surface of the fixed ring 14 is provided with a second slide rail 142 along the circumferential direction. The lower end of the sliding component 1 23 is fixedly provided with a sliding component 24.
