DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Embodiment 1:

[0029] Reference Figure 1-4 The online precision pH detector includes a detector body 1, a detection head 101 is connected to the detector body 1, and also includes: a shell 2, which is arranged on the detector body 1, a cavity 203 is arranged in the shell 2, and the detection head 101 is inserted in the cavity 203; a rotating plate 205, which is rotatably connected in the cavity 203, and a plurality of mounting frames 3 are fixedly connected to the rotating plate 205; a plurality of fixing rings 4, which are all fixedly connected to the mounting frame 3; an insert block 501, which is rotatably connected in the fixing ring 4, and a cleaning head is connected to the insert block 501 502, the cleaning end of the cleaning head 502 is facing the center of the shell 2, the cleaning head 502 is a conventional brush, and can also be a sponge. At the same time, the cleaning head 502 needs to be able to stick to the cleaning head 101 to clean the detection head 101; the liquid inlet pipe 201 is fixedly connected to the top of the shell 2; the liquid outlet pipe 202 is fixedly connected to the bottom of the shell 2, the fixed ring 4 is provided with a sliding groove 401, the insert block 501 is connected to a throw block 503, the throw block 503 is slidably connected in the sliding groove 401, and the sliding groove 401 is located Figure 4 As shown, at this time, the swing block 503 is in a naturally hanging state, the length of the sliding groove 401 on one side is obviously greater than the length of the sliding groove 401 on the other side, a driving motor 204 is fixedly connected in the shell 2, the output end of the driving motor 204 is fixedly connected to the rotating plate 205, a control valve is provided in the liquid outlet pipe 202, and the rotating plate 205 matches the cavity 203.

[0030] The detector body 1 in the device is an existing intelligent device, which can be remotely controlled by a computer, and then the position of the detection head 101 can be adjusted so that the detection head 101 can enter the liquid to be detected, and then the pH value can be measured.

[0031] When the device is in use, the detection head 101 is inserted into the liquid to be detected through the detector body 1, and then the pH value is measured until the amino acid product is adjusted to a suitable pH range to facilitate the maximum precipitation and extraction of the product. The specific adjustment and measurement standards need to be set according to the actual production environment and needs.

[0032] After the measurement is completed, some liquid remains on the detection head 101. At this time, the liquid inlet pipe 201 is started, and clean water from the outside will enter the shell 2 through the liquid inlet pipe 201. At the same time, the driving motor 204 is started, and the mounting frame 3 rotates, thereby causing the cleaning head 502 to rotate in a circle. At the same time, as the mounting frame 3 rotates, it will drive the flow of water in the shell 2 to flow in a spiral shape. At this time, the remote online control of the detector body 1 can be provided, and the detection head 101 is inserted into the shell 2. At this time, the water and the cleaning head 502 will clean the detection head 101. Figure 4 As shown, the arrangement of the sliding groove 401, when the driving motor 204 drives the mounting frame 3 to rotate, the swing block 503 will be close to Figure 4 The sliding groove 401 on the right side in the middle (the direction of movement is related to the rotation direction of the drive motor 204. It is common knowledge that the direction is used to make the swing block 503 close to the shorter end, which is the shorter end. At this time, the swing block 503 will be close to the sliding groove 401. After the subsequent drive motor 204 rotates for a period of time, the drive motor 204 will stop suddenly. At this time, the swing block 503 will quickly move away from the sliding groove 401 at the shorter end under the action of its own weight, and slide quickly in the sliding groove 401, hitting the other end of the sliding groove 401. The movement at this time will drive the rotation of the cleaning head 502. At the same time, the subsequent collision will produce a certain amount of vibration, which will cause impurities on the cleaning head 502 to fall off, thereby playing a cleaning role. At this time, the control valve in the liquid outlet pipe 202 can be opened to discharge the sewage, and the detection head 101 can be taken out through the detector body 1. At this time, the cleaning of the detection head 101 is completed, which is convenient for subsequent use.

[0035] The threaded installation method makes it easy to disassemble and replace the cleaning head 502 later.

[0036] The utility model can clean the surface of the detection head 101 by configuring the housing 2 and the cleaning head 502 so that the cleaning head 502 rotates in a circle. Meanwhile, the rotation process causes water to flow, thereby promoting the cleaning effect.
