Description

Technical Field

[0001] The utility model relates to the field of concrete mixing auxiliary equipment, in particular to a mixer monitoring device. Background Art

[0002] The mixer is the core equipment of the concrete mixing station. It is used to mix building materials such as fly ash, cement, sand, various dry mortars and admixtures. When working, water also needs to be added to the mixer to mix the components evenly.

[0003] When the mixer is working, it is necessary to observe its internal situation. Since the mixer is a closed structure, it is usually necessary to open an observation window. This observation method has the disadvantages of dim internal light, and the observer cannot effectively monitor the mixer. Moreover, dust and smoke will come out when the observation window is opened. Therefore, it is necessary to provide a monitoring device that is convenient for observing its internal situation. The prior art, "such as authorization announcement number CN218307706 U, name: mixer monitoring device" discloses a mixer monitoring device, including a mounting seat, a camera, a control button, a controller, a solenoid valve, a cylinder, a cylinder telescopic rod and a door panel, etc. The device has the disadvantages of complex structure, high use and installation cost, etc. Therefore, it is necessary to provide a mixer monitoring device with a simple structure, easy use, and capable of observing the internal situation of the mixer. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a mixer monitoring device in view of the defects of the prior art. The device has a simple structure, is easy to use, and can observe the internal conditions of the mixer.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a mixer monitoring device, comprising a conical cylinder, an air inlet heating box, a camera and a high-pressure air inlet pipe, a mounting bracket is provided on the top of the conical cylinder, the camera is installed on the mounting bracket, and the camera is used to monitor the internal situation of the mixer; an inlet fan and an electric heating pipe are provided inside the air inlet heating box; the air outlet port of the inlet fan is connected to the top of the conical cylinder; air inlets are symmetrically provided on two sides of the air inlet heating box; the electric heating pipe is placed on the top of the air inlet heating box, and is used to heat the air inside the air inlet heating box; the air inlet end of the high-pressure air inlet pipe is connected to the hydraulic station air pipe, and its air outlet is located below the camera; it is used to blow away dust and water vapor on the surface of the camera.

[0006] Preferably, the electric heating tube is a U-shaped electric heating tube.

[0007] Preferably, each of the two symmetrical sides of the air inlet heating box is provided with three air inlets.

[0008] Preferably, the top of the cone is also provided with an inspection opening, and the inspection opening is provided with an inspection door.

[0009] Preferably, the camera is a stainless steel light-controlled camera.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model utilizes an inlet fan to guide air into the cone cylinder, and utilizes an electric heating tube to heat the air entering the cone cylinder. The advantage of sending hot air into the cone cylinder is that part of the dust and water vapor on the surface of the camera can be blown away, and the hot air can play a drying role, which can volatilize the water vapor on the surface of the camera and avoid condensation of water vapor to affect its monitoring effect; secondly, using a high-pressure air inlet pipe to blow high-pressure gas to the surface of the camera can further blow away the dust on the surface, and the monitoring effect is better. The utility model has a simple structure, is easy to use, and has low use and installation costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] like Figures 1 to 3 As shown, the utility model is a mixer monitoring device, comprising a cone cylinder 1, an air inlet heating box 2, a camera 3 and a high-pressure air inlet pipe 4. A mounting bracket 11 is provided on the top of the cone cylinder 1, and a camera 3 is installed on the mounting bracket 11. The camera 3 of the utility model is a stainless steel light-controlled camera (selected from existing equipment). When this camera is working, the light can automatically control the light, so as to better monitor the situation inside the mixer. The camera 3 is used to monitor the situation inside the mixer;

[0018] The air inlet heating box 2 is provided with an air inlet fan 21 and an electric heating tube 22, and the electric heating tube 22 is a U-shaped electric heating tube; the air outlet port 211 of the air inlet fan 21 is connected to the top of the cone 1; the air inlets 23 are symmetrically provided on the two sides of the air inlet heating box 2, and each side of the utility model is provided with 3 air inlets 23; the electric heating tube 22 is placed on the top of the air inlet heating box 2, and is used to heat the air inside the air inlet heating box 2; the air inlet end of the high-pressure air inlet pipe 4 is connected to the hydraulic station air pipe, and its air outlet 41 is located below the camera 3; it is used to blow away the dust and water vapor on the surface of the camera 3. In order to facilitate regular maintenance of the camera 3, an inspection port 5 is also provided at the top of the cone 1, and the inspection port 5 is provided with an inspection door 51, and the inspection door 51 is installed on the inspection port 5 through hinges.

[0019] The specific use and working principle of the utility model are as follows: Figure 4 As shown, each device is Figures 1 to 3 After the assembly is completed, the bottom of the cone 1 is welded to the opening at the top of the mixer 10. The opening and closing of the air inlet fan 21, the electric heating tube 22, the camera 3 and the high-pressure air inlet pipe 4 in the utility model can be automatically controlled according to the PLC controller. When the concrete mixing station is working, the above-mentioned equipment is automatically turned on, and the electric heating tube 22 is used to heat the air entering the cone 1. The advantage of sending hot air into the cone 1 is that part of the dust and water vapor on the surface of the camera 3 can be blown away, and the hot air can play a drying role, which can volatilize the water vapor on the surface of the camera 3 and avoid condensation of water vapor to affect its monitoring effect; secondly, using the high-pressure air inlet pipe 4 to blow high-pressure gas to the surface of the camera 3 can further blow away the dust on its surface. Of course, an air filter valve can be added in the middle of the high-pressure air inlet pipe 4 to filter out moisture and impurities in the air, so that the monitoring effect is better. When the concrete mixing station stops working, the operation of the above-mentioned equipment will also stop automatically.

[0020] The above is a detailed description of the implementation methods of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the described implementation methods. For those skilled in the art, without departing from the principle and spirit of the utility model, various changes, modifications, substitutions and variations are made to these implementation methods, which still fall within the scope of protection of the utility model. Finally, it should be noted that the contents not described in detail in the specification belong to the prior art known to professional and technical personnel in the field, and those skilled in the art can realize them without creative work, so they will not be repeated here.
