Description

Technical Field

[0001] The utility model belongs to the technical field of pH detection, and particularly relates to a pH detection device. Background Technique

[0002] The pH value of meat products is an important factor determining their freshness, taste and overall quality. During the spoilage process of meat, the pH value will change. Therefore, by measuring the pH value of the canned pork with pickled mustard tuber, it can help us judge its freshness and ensure that the product meets the quality standards. Although canned food has been sterilized, it may still be contaminated by microorganisms during production, storage and transportation. Different types of microorganisms have different adaptabilities to the pH value. By detecting the pH value, the growth of microorganisms in the can can be indirectly evaluated, thus ensuring the safety of the product. Therefore, a pH detection device is needed to detect the pH value.

[0003] In the existing pH detection devices, most of them directly insert and install the pH detection rod inside the can for pH detection during detection. The pH detector being soaked in the solution for a long time is likely to cause situations such as inaccurate subsequent pH detection values, affecting subsequent pH detection. Therefore, a pH detection device is needed to assist in solving this problem. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0027] This detailed implementation mode is a PH detection device, as Figure 1 、 Figure 2 and Figure 3 shown. The PH detection device includes a mounting cylinder 1. A top cover 4 is installed at the top of the mounting cylinder 1. The inside of the mounting cylinder 1 is hollow. A PH detection rod 72 is installed inside the mounting cylinder 1. Conduction grooves are symmetrically opened inside the mounting cylinder 1. A first blocking plate 6 and a second blocking plate 7 are respectively slidably arranged at the conduction grooves. Both the first blocking plate 6 and the second blocking plate 7 are U-shaped. The outer side edges of the mounting cylinder 1 are symmetrically protruded with conduits 2. A conduction cavity 21 is opened inside the conduits 2. Communication holes 61 are equidistantly opened at the conduction grooves. The communication holes 61 are communicated with the conduction cavity 21. A conduction tube 5 communicated with the conduction cavity 21 is installed on the top cover 4. A first conduction hole 62 is opened on the first blocking plate 6. The communication holes 61 and the first conduction hole 62 are arranged in a staggered manner. The outer side edge of the mounting cylinder 1 and near the bottom is symmetrically protruded with blocking tubes 3. The conduits 2 and the blocking tubes 3 are arranged in a staggered manner. A guide hole is drilled at the conduction groove covering the second blocking plate 7. The guide hole penetrates the mounting cylinder 1. Second conduction holes 71 are equidistantly opened on the second blocking plate 7. The second conduction holes 71 are communicated with the guide hole.

[0028] By setting the mounting tube 1 and the first baffle plate 6 and the second baffle plate 7, the PH detection rod 72 can be separately installed inside the hollow mounting tube 1 during operation, and in subsequent detection, the positions of the first baffle plate 6 and the second baffle plate 7 can be adjusted to send the liquid in the can into or out of the mounting tube 1, thereby ensuring that the PH detection rod 72 can contact with the liquid during operation and can conveniently discharge the entire liquid after operation, thereby avoiding as much as possible the situation where the PH detection rod 72 is in contact with the liquid for a long time, resulting in inadequate PH detection, etc.

[0029] A reset cavity is provided in the above-mentioned conducting groove, and a tensioning assembly 13 is installed in the reset cavity to assist in adjusting the position of the first blocking plate 6 and the second blocking plate 7. The tensioning assembly 13 includes a guide rod 14 vertically fixed in the reset cavity, and the first blocking plate 6 and the second blocking plate 7 are both sleeved on the guide rod 14 at the bottom, and a reset spring 15 is sleeved on the guide rod 14 to assist in pushing the guide rod 14.

[0030] By setting the tensioning assembly 13, the reset spring 15 is in the pushed-out state during operation, thereby ensuring that the first blocking plate 6 and the second blocking plate 7 are in corresponding positions, thereby preventing external liquid from entering the interior of the mounting tube 1 when not working, and ensuring the overall sealing of the interior of the mounting tube 1 when not working.

[0031] Reference Figure 1 , Figure 2 and Figure 4 As shown, an auxiliary adjustment component 8 is installed at the top of the mounting tube 1, and the adjustment component 8 includes an adjustment motor 9 installed at the top of the top cover 4. A sleeve 10 is fixed to the front end of the shaft of the adjustment motor 9. The sleeve 10 extends into the interior of the mounting tube 1. A screw rod 11 is installed on the sleeve 10. The screw rod 11 is located between the first baffle plate 6 and the second baffle plate 7. The sleeve 10 and the screw rod 11 are threadedly matched. Through the setting of the adjustment component 8, the first baffle plate 6 and the second baffle plate 7 can be effectively positioned during work to ensure that the liquid can stably enter the interior of the mounting tube 1.

[0032] A cross-shaped fixing frame 12 is fixed inside the above-mentioned installation tube 1, and a limiting rod 121 is fixed on the fixing frame 12. The limiting rod 121 is a rectangular rod-shaped structure. The limiting rod 121 is passed through and installed on the screw rod 11. Through the setting of the limiting rod 121, it can be ensured that the screw rod 11 can only move straight up and down during operation, thereby ensuring that the screw rod 11 can be effectively adjusted.

[0033] Reference Figure 1 and Figure 5As shown, the top cover 4 is symmetrically provided with mounting holes, and a positioning assembly 16 for auxiliary positioning is installed at the mounting hole. The positioning assembly 16 is installed in a fixed hole at the top of the can. The positioning assembly 16 includes an insert cylinder 17 fixed at the mounting hole, an extrusion cavity is provided on the insert cylinder 17, and a rotating rod 18 is threadedly installed in the extrusion cavity. A sliding cavity is symmetrically provided on the insert cylinder 17, and an ejection column 19 is slidably arranged in the sliding cavity. A sleeve disk 191 is sleeved on the outer edge of the ejection column 19, and an ejection spring 20 pushed by the auxiliary sleeve disk 191 is installed in the sliding cavity.

[0034] By setting the positioning assembly 16, the rotating rod 18 is rotated, and the plug-in cylinder 17 and the rotating rod 18 are threadedly matched, so that the rotating rod 18 is lowered as a whole. In the process of the rotating rod 18 descending, the ejection column 19 is pushed, so that the ejection column 19 is inserted and installed in the fixing hole, and in the process of the ejection column 19 being pushed, the ejection spring 20 is pushed and compressed, so that the installation cylinder 1 can be quickly disassembled and replaced in the subsequent work process, and the inconvenience of replacing the installation cylinder 1 can be avoided as much as possible.

[0035] Working principle:

[0036] When it is necessary to inspect the inside of the canned winter vegetable and pork, first, insert the installation tube 1 at the corresponding position, and extend the insertion tube 17 into the fixing hole, rotate the rotating rod 18, and the threaded fit between the insertion tube 17 and the rotating rod 18 causes the rotating rod 18 to drop as a whole. In the process of the rotating rod 18 dropping, the ejection column 19 is pushed, so that the ejection column 19 is inserted and installed in the fixing hole, and in the process of the ejection column 19 being pushed, the ejection spring 20 is pushed and compressed.

[0037] Before the detection is needed, the conducting pipe 5 is connected and installed at the water inlet pipe and the water outlet pipe respectively, and the adjusting motor 9 is started. The adjusting motor 9 drives the sleeve 10 to rotate forward as a whole. The sleeve 10 and the screw rod 11 are threadedly matched, so that the screw rod 11 is lowered as a whole. In the process of the screw rod 11 descending, the second blocking plate 7 is driven to be pushed downward. In the process of the second blocking plate 7 descending, the second conducting hole 71 is driven to descend as a whole, so that the second conducting hole 71 is connected with the conducting hole, so that the liquid inside the can enters the inside of the installation cylinder 1. At this time, the second blocking plate 7 is restored to the corresponding position. At this time, the pH inside the installation cylinder 1 is detected and processed by the pH detection rod 72. After the detection is completed, the adjusting motor 9 is started. The adjusting motor 9 drives the sleeve 10 to flip as a whole. At this time, the screw rod 11 rises, and drives the first blocking plate 6 to rise as a whole, and the connecting hole 61 is connected with the first conducting hole 62. At this time, the conducting pipe 5 is filled with water, and the liquid inside the installation cylinder 1 is discharged as a whole through the drain pipe, thereby completing the overall replacement and emptying of the liquid. After the liquid is emptied, the overall sealing of the inside of the installation cylinder 1 is maintained.

[0038] All the technical features in this embodiment can be freely combined according to actual needs.
