Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, and particularly relates to a peristaltic pump pipeline pressure detection device. Background Art

[0002] A peristaltic pump, also known as a hose pump or tube pump, is a special type of pump that can drive fluid to move forward by squeezing a hose. Peristaltic pumps have been widely used in the fields of food, medicine, chemical industry, etc. For example, in the automatic cooking machine industry, in order to accurately control the weight of various seasonings, the seasonings are mostly formulated into seasoning solutions, and then the seasoning solutions are quantitatively transported into the frying pan through a peristaltic pump. However, due to the characteristics of the peristaltic pump's own structure, after being used for a period of time, the conveying capacity of the peristaltic pump will decay to varying degrees. In order to master the actual working ability of the peristaltic pump, the staff needs to monitor and measure the corresponding parameters (such as pressure) of the fluid in the pipeline, so as to adjust the working parameters of the peristaltic pump at any time to make the peristaltic pump always meet the expected working requirements.

[0003] In the prior art, many pipeline pressure monitoring devices need to open holes in the corresponding pipelines, then place the monitoring elements into the pipes, and make the monitoring elements directly contact the fluid. Although the measurement results of this measurement method will be more direct, accurate and reliable, it needs to damage the pipeline and is prone to causing pollution of the fluid in the pipe, which is not very suitable for measuring the peristaltic pump pipeline of the cooking machine. Therefore, the present application aims to provide a detection device that does not need to damage the pipeline, does not contact the fluid in the pipe, and can measure the pressure in the peristaltic pump pipeline at any time. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above deficiencies of the prior art and provide a peristaltic pump pipeline pressure detection device that does not need to contact the fluid and can monitor the pressure in the pipeline outside the pipeline.

[0005] The technical solution of the utility model is: a peristaltic pump pipeline pressure detection device, including a measurement seat, an electronic scale, a pressure head and an adjusting member. A pipeline groove and an installation cavity are arranged on the measurement seat. The electronic scale is arranged in the installation cavity. A communication hole is arranged between the installation cavity and the pipeline groove. The pressure head is installed in the communication hole. One end of the pressure head is connected to the electronic scale, and the other end of the pressure head passes through the communication hole and extends into the pipeline groove. The adjusting member is used to fix the electronic scale in the installation cavity and adjust the distance that the pressure head extends into the pipeline groove.

[0006] Further, the measurement seat is in the shape of a rectangular plate. The pipeline groove and the installation cavity are arranged on the same side surface of the rectangular plate. The installation cavity is a rectangular groove, and the pipeline groove is parallel to a certain side of the rectangular groove.

[0007] Further, the depth of the installation cavity is the same as that of the pipeline groove, and both are one-third of the thickness of the measuring seat.

[0008] Further, the depth and width of the pipeline groove are not less than the outer diameter of the peristaltic pump pipeline to be measured.

[0009] Further, the adjusting member is a bolt.

[0010] Further, threaded holes mating with the adjusting member are provided on the measuring seat.

[0011] Further, the threaded holes and the communication holes are coaxially arranged.

[0012] Further, the communication holes are opened in the middle of the side wall of the rectangular groove.

[0013] Further, anti-slip portions are provided on the side walls of the pipeline groove, and the anti-slip portions are used to prevent the peristaltic pump pipeline from sliding in the pipeline groove.

[0014] Further, the anti-slip portions are tooth patterns provided on the side walls of the pipeline groove.

[0015] Further, the electronic scale is a micro electronic scale, and the electronic scale can be connected to the control center of the cooking machine wirelessly or wiredly, so that the measured value of the electronic scale can be fed back to the control center of the cooking machine. After the control center processes the value, if the value exceeds the expected value, an alarm can be issued to remind the staff to check the pipeline. The electronic scale can also be replaced by a pressure sensor.

[0016] The beneficial effects of the present utility model compared with the prior art: The present utility model combines a micro electronic scale and a pressure head, and utilizes the principle of traditional Chinese medicine pulse-taking to realize the monitoring of the internal pressure of the pipeline without damaging the pipeline and without contacting the fluid in the pipeline, so there is no problem of polluting the fluid. Moreover, the pipeline can be quickly clamped through the pipeline groove and can be clamped at any position of the pipeline; at the same time, the volume of the whole device is small, and multiple devices can be connected in series at will, which is convenient for monitoring different segments of the same pipeline.

[0023] The following will further elaborate on the present utility model in conjunction with specific embodiments. The methods or functional components not specifically described in the embodiments are all prior arts; unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs.

[0024] Embodiment 1

[0025] As Figures 1-5 shown, this embodiment is a pressure detection device for a peristaltic pump pipe 5, including a measuring seat 3, an electronic scale 1, a pressure head 4 and an adjusting member. A pipe groove 32 and an installation cavity 31 are provided on the measuring seat 3. The electronic scale 1 is arranged in the installation cavity 31. A communication hole 33 is provided between the installation cavity 31 and the pipe groove 32. The pressure head 4 is installed in the communication hole 33. One end of the pressure head 4 is connected to the electronic scale 1, and the other end of the pressure head 4 passes through the communication hole 33 and extends into the pipe groove 32. The adjusting member is used to fix the electronic scale 1 in the installation cavity 31 and adjust the distance that the pressure head 4 extends into the pipe groove 32.

[0026] In this embodiment, the measuring seat 3 is in the shape of a rectangular plate. The pipe groove 32 and the installation cavity 31 are arranged on the same side surface of the rectangular plate. The installation cavity 31 is a rectangular groove. The pipe groove 32 is parallel to a certain side of the rectangular groove. The installation cavity 31 and the pipe groove 32 have the same depth, and the depth is about one-third of the thickness of the measuring seat 3.

[0027] In this embodiment, the adjusting member is a bolt 2. Threaded holes 34 cooperating with the adjusting member are provided on the measuring seat 3. The threaded holes 34 and the communication holes 33 are coaxially arranged. And the communication holes 33 are opened in the middle of the side wall of the rectangular groove. In this embodiment, the electronic scale 1 adopts a micro electronic scale 1. The micro electronic scale 1 is a prior art and will not be elaborated here.

[0028] When the pipeline 5 pressure detection device in this embodiment is in use, the pipeline 5 of the peristaltic pump is embedded in the pipeline groove 32, and the adjusting member is rotated to adjust the relative position of the electronic scale 1 in the installation cavity 31, thereby changing the distance that the pressure head 4 extends into the pipeline groove 32 until the electronic scale 1 can detect the change in the internal pressure of the pipeline and display the relevant value. If the fluid pressure in the pipeline 5 is normal, the value displayed by the electronic scale 1 will also be stable within the normal range. If the pipeline 5 is damaged or the like, the fluid pressure in the pipeline 5 will change greatly, and the value of the electronic scale 1 will also change greatly.

[0029] In some other embodiments, an anti-slip portion may also be provided on the side wall of the pipeline groove 32. The anti-slip portion is used to prevent the peristaltic pump pipeline 5 from sliding in the pipeline groove 32. The anti-slip portion is a tooth pattern provided on the side wall of the pipeline groove 32.

[0030] In some other embodiments, the electronic scale 1 can also communicate with the control center of the cooking machine wirelessly or wiredly, so that the value measured by the electronic scale 1 can be directly fed back to the control center of the cooking machine. After the control center processes the value, if it is found that the value exceeds the expected value, an alarm can be issued to remind the staff to check the corresponding pipeline 5.

[0031] The above are only some embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have combinations and variations of the foregoing various technical features. Without departing from the spirit and scope of the present invention, the improvements, variations, equivalent substitutions of the present invention, or the use of the structure or method of the present invention in other fields to achieve the same effect all belong to the protection scope included in the present invention.
