Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a mixer capable of being cleaned in place. Background Art

[0002] In modern pharmaceutical, food, chemical and other industries, mixers are essential production equipment. However, after mixing materials in the mixer, some materials will remain inside the mixer. If these residual materials are not cleaned in time, they will cause contamination to subsequent mixing operations and affect production quality.

[0003] The emergence of in-place cleaning technology meets the need for quick cleaning of mixers. In-place cleaning not only improves cleaning efficiency, but also allows cleaning operations to be performed directly at the equipment installation location, avoiding frequent disassembly and cleaning of the mixer and extending the mixer's service life. However, current in-place cleaning methods for mixers typically only use an external water inlet pipe for cleaning. The cleaning water used is disposable and not reused, resulting in a large amount of water used to clean the mixer. In order to save water for cleaning mixers, a in-place cleaning technology that combines external cleaning and internal circulation cleaning is urgently needed for cleaning mixers. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and to provide a mixer that can be cleaned in place.

[0009] A connecting rod is provided at one end of the cleaning pipe away from the cleaning cover, a cleaning ball is provided at the end of the connecting rod, and a plurality of reinforcing convex rings are provided at intervals on one end of the cleaning pipe close to the cleaning ball.

[0010] The included angle a between the cleaning pipe and the cleaning cover is 30° to 60°.

[0011] The fourth pipeline is provided with a Y-type filter.

[0012] The Y-type filter includes a first flow hole, a second flow hole, a flange and a filter cartridge. The filter cartridge is provided with a filter hole.

[0027] Example 1:

[0028] like Figures 1 to 4 As shown, this is an embodiment provided by the utility model:

[0029] In order to realize the two modes of external cleaning and internal circulation cleaning, a mixer capable of in-situ cleaning includes a water inlet pipe 1, a cleaning cover 2, a mixer 3 and a discharge port 4, wherein the water inlet pipe 1 is used for an external water source, the cleaning cover 2 abuts against the upper end of the mixer 3 and a cleaning pipe 21 is provided in the middle thereof, the water inlet pipe 1 is connected to the cleaning pipe 21 through a first pipe 5, a drainage interface 31 is provided at the lower end of the mixer 3, the drainage interface 31 is connected to a second pipe 6, the second pipe 6 is connected to a third pipe 7 and a cleaning pump 8 through a three-way valve 10 at one end away from the drainage interface 31, the third pipe 7 is connected to the discharge port 4 at one end away from the cleaning pump 8, the cleaning pump 8 is connected to the first pipe 5 through a fourth pipe 9, and a valve 11 is provided on the side of the third pipe 7 close to the second pipe 6. The water inlet pipe 1, the first pipe 5, the cleaning pipe 21, the drainage interface 31, the second pipe 6, the third pipe 7, and the discharge port 4 form an external cleaning channel for preliminary cleaning of the hopper cavity, removing most of the material residue and discharging it from the discharge port 4. During external cleaning, the cleaning pump 8 is in the off state. The cleaning pump 8 is turned on and the valve 11 and the external water source on the water inlet pipe 1 are closed. The first pipe 5, the cleaning pipe 21, the drainage interface 31, the second pipe 6, and the fourth pipe 9 form an internal circulation cleaning channel for circulating cleaning of the hopper cavity. After cleaning is completed, the cleaning pump 8 is turned off and the valve 11 is opened to drain water.

[0030] In order to sample the water quality during cleaning to ensure the cleaning effect, a fifth pipe 12 is provided on the third pipe 7. The fifth pipe 12 is U-shaped and connected to both sides of the valve 11. A sampling valve 13 is provided on the fifth pipe 12.

[0031] A connecting rod 212 is provided at the end of the cleaning pipe 21 away from the cleaning cover 2. A cleaning ball 213 is mounted at the end of the connecting rod 212. Several reinforcing rings 211 are spaced apart on the end of the cleaning pipe 21 near the cleaning ball 213. The cleaning balls 213 help remove residual material from the hopper, improving cleaning efficiency. The reinforcing rings 211 increase the strength of the cleaning pipe 21, thereby resisting the impact of the cleaning ball 213 on the cleaning pipe 21 during flushing. The angle a between the cleaning pipe 21 and the cleaning cover 2 is 30° to 60°.

[0032] In order to filter the cleaning water in time during the internal circulation cleaning process and prevent residual materials from contaminating the hopper cavity again or blocking the internal circulation cleaning channel as the water circulates, a Y-type filter 14 is provided on the fourth pipe 9.

[0033] The Y-shaped filter 14 includes a first flow hole 141, a second flow hole 142, a flange 143, and a filter cartridge 144. The filter cartridge 144 is provided with a filter hole 145. The first flow hole 141 communicates with the second flow hole 142 through the filter hole 145. The first flow hole 141 and the second flow hole 142 are coaxially arranged. The filter cartridge 144 is offset from the first flow hole 141 and the second flow hole 142. Water can flow through the first flow hole 141, the filter hole 145, and the second flow hole 142, while material residue carried by the water is filtered and deposited in the filter cartridge 144.

[0034] In order to clean or replace the filter cartridge 144 in a timely manner, a cover plate 146 is provided at one end of the filter cartridge 144 away from the first flow hole 141 , and the cover plate 146 is detachably connected to the filter cartridge 144 .

[0035] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
