Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement mortar testing equipment, and in particular to a cement mortar mixing pot wetting device. Background Technology
[0002] In cement mortar strength testing, the wetting state of the mixing pot directly affects the initial humidity and uniformity of the mortar mixture, thus determining the accuracy of the test results. According to construction specifications, the inner wall of the mixing pot must be kept uniformly moist before mixing to avoid deviations in the mix ratio caused by the mortar raw materials adsorbing onto the dry pot wall. In the existing technology, the wetting of the mixing pot is mostly done manually, specifically by the operator holding a water sprayer to spray water onto the inner wall of the pot or wiping the pot wall with a damp cloth.
[0003] However, this artificial wetting method has the following drawbacks:
[0004] Firstly, the wetting uniformity is poor. Manual water spraying can easily lead to localized areas being too wet or too dry, especially the corners of the mixing pot, which are difficult to cover, resulting in uneven distribution of components in the mortar during the mixing process.
[0005] Secondly, the water consumption control accuracy is low. Operators rely on experience to judge the amount of water to be sprayed, which makes it impossible to achieve quantitative water supply. Differences in operation by different personnel can easily lead to experimental errors.
[0006] Third, the operation efficiency is low, with each wetting taking 1-2 minutes. In batch testing scenarios, manual operation is difficult to meet the requirements of efficient testing.
[0007] Fourth, there are safety hazards. Water can easily splash onto surrounding equipment during manual operation, which may cause electrical failures or the risk of people slipping and falling.
[0008] Therefore, there is an urgent need to design a device that can achieve precise, uniform, and automated wetting, to solve the drawbacks of traditional manual wetting methods and improve the standardization level of cement mortar testing. Utility Model Content
[0009] The purpose of this invention is to provide a wetting device for a cement mortar mixing pot to solve the problems mentioned in the background art.
[0010] To achieve the above objectives, this utility model provides the following technical solution: a cement mortar mixing pot wetting device, comprising a water supply module installed on one side of a cement mortar mixer, a spraying module installed at one end of the water supply module, and a rotating support plate for fixing the mixing pot disposed below the spraying module. The spraying module includes a water outlet pipe and a liftable atomizing nozzle. The rotating support plate rotates to move the mixing pot to the bottom of the water outlet pipe or the atomizing nozzle, and the interior of the mixing pot is wetted through the atomizing nozzle; water is added to the interior of the mixing pot during mortar preparation through the water outlet pipe.
[0011] Preferably, it also includes a control module, which includes a PLC controller installed on the cement mortar mixer and an in-situ sensor installed on the outer wall of the cement mortar mixer and located below the atomizing nozzle. The in-situ status of the mixing pot is detected by multiple in-situ sensors at different heights to determine the current size of the mixing pot.
[0012] Preferably, the water supply module includes a support frame and a water tank fixedly embedded in the support frame, and a liquid level sensor is installed inside the water tank.
[0013] Preferably, a water pump is installed at the bottom of the water tank, and a three-way solenoid valve is installed between the output end of the water pump and the water outlet pipe and the atomizing nozzle.
[0014] Preferably, a hollow tube is fixedly installed on the top of the atomizing nozzle, the hollow tube is slidably disposed in the support frame, and a connecting hose connecting the three-way solenoid valve and the atomizing nozzle is inserted inside the hollow tube.
[0015] Preferably, an electric telescopic rod is fixedly installed on the top of the support frame, and the output end of the electric telescopic rod is fixedly connected to the top end of the hollow tube.
[0016] Preferably, the outer end of the rotating support plate is provided with a mounting groove, and a threaded pin for fixing the mixing pot is threadedly connected in the mounting groove.
[0017] Preferably, a positioning pin is movably inserted into the inner end of the rotating support plate, and the outer end of the rotating support plate can be locked at a preset position by the positioning pin.
[0018] The technical effects and advantages of this utility model are as follows:
[0019] In use, by pulling out the positioning pin, the rotating support plate is rotated 90° to one side, and then the positioning pin is inserted into another positioning hole. At this time, the mixing pot is located below the atomizing nozzle. The PLC controller is then activated, and multiple on-site sensors are used to detect the position status of the mixing pot. The size of the mixing pot is determined based on its height. Then, the PLC controller drives the output end of the electric telescopic rod to extend according to the size of the mixing pot, so that the atomizing nozzle is inserted into the mixing pot. At the same time, the water pump is controlled according to the size of the mixing pot to pump out the preset total amount of water. The water is evenly sprayed onto the inner wall of the mixing pot through the atomizing nozzle. Then, the output end of the electric telescopic rod retracts and resets. The overall operation is simple, the automated spraying is more uniform and safer, and it can automatically pump out an appropriate amount of water for wetting according to the size of the mixing pot.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides, for example Figures 1 to 4 The illustrated cement mortar mixing pot wetting device includes a water supply module 1 installed on one side of the cement mortar mixer. A spraying module 2 is installed at one end of the water supply module 1. A rotating support plate 3 for fixing the mixing pot is provided below the spraying module 2. The spraying module 2 includes a water outlet pipe 24 and a liftable atomizing nozzle 23. The rotating support plate 3 rotates to move the mixing pot to the bottom of the water outlet pipe 24 or the atomizing nozzle 23, and the interior of the mixing pot is wetted through the atomizing nozzle 23. Water is added to the interior of the mixing pot during mortar preparation through the water outlet pipe 24.
[0027] It also includes a control module, which includes a PLC controller 4 installed on the cement mortar mixer and an in-situ sensor 5 installed on the outer wall of the cement mortar mixer and located below the atomizing nozzle 23. The in-situ status of the mixing pot is detected by multiple in-situ sensors 5 at different heights to determine the current size of the mixing pot.
[0028] The water supply module 1 includes a support frame 11 and a water tank 12 fixedly embedded in the support frame 11. A liquid level sensor is installed inside the water tank 12 to monitor the water volume inside the water tank 12. When the water level is low, an alarm is triggered by the PLC controller 4.
[0029] A water pump 25 is installed at the bottom of the water tank 12, and a three-way solenoid valve 26 is installed between the output end of the water pump 25, the water outlet pipe 24, and the atomizing nozzle 23.
[0030] A hollow tube 22 is fixedly installed on the top of the atomizing nozzle 23. The hollow tube 22 is slidably disposed in the support frame 11, and a connecting hose connecting the three-way solenoid valve 26 and the atomizing nozzle 23 is inserted inside the hollow tube 22. An electric telescopic rod 21 is fixedly installed on the top of the support frame 11. The output end of the electric telescopic rod 21 is fixedly connected to the top of the hollow tube 22. Multiple on-site sensors 5 are used to detect the position status of the mixing pot. The size of the mixing pot is determined according to the height. Then, the PLC controller 4 drives the output end of the electric telescopic rod 21 to extend a preset length according to the size of the mixing pot, so that the atomizing nozzle 23 is inserted into the mixing pot.
[0031] The outer end of the rotating support plate 3 is provided with an installation groove 33, and a threaded pin 34 for fixing the mixing pot is threadedly connected in the installation groove 33. This is used to fix the mixing pot at a designated position on the rotating support plate 3, so that it can be concentric with the atomizing nozzle 23 when wetting, and the spraying is more uniform. When mixing mortar, it can be concentric with the mixing head, and the mixing head is prevented from colliding with the inner wall of the mixing pot.
[0032] The inner end of the rotating support plate 3 is movably connected to a positioning pin 32, which allows the outer end of the rotating support plate 3 to be locked in a preset position.
[0033] Working principle: This device is modified based on the original cement mortar mixer. The rotating support plate 3 is rotatably installed on the original mixing pot support through bearings, and at least two positioning holes adapted to the positioning pins 32 are opened on the mixing pot support.
[0034] In use, by pulling out the positioning pin 32, the rotating support plate 3 is rotated 90° to one side, and then the positioning pin 32 is inserted into another positioning hole. At this time, the mixing pot is located below the atomizing nozzle 23. At this time, by starting the PLC controller 4, multiple on-site sensors 5 are used to detect the position status of the mixing pot. The size of the mixing pot is determined according to the height (usually 1.5L, 2L, 3L). Then, the PLC controller 4 drives the output end of the electric telescopic rod 21 to extend the preset length according to the size of the mixing pot, so that the atomizing nozzle 23 is inserted into the mixing pot. At the same time, the water pump 25 is controlled according to the size of the mixing pot to pump out the preset total spray volume, which is evenly sprayed on the inner wall of the mixing pot through the atomizing nozzle 23. Then, the output end of the electric telescopic rod 21 retracts and resets.
[0035] At this point, pull out the positioning pin 32, rotate the rotating support plate 3 90° in the opposite direction, and then insert the positioning pin 32 into the initial positioning hole. At this point, the mixing pot is located below the mixing head of the cement mortar mixer. Add the mortar raw materials, raise the mixing pot to a higher position using the mixing pot support, change the water outlet direction using the three-way solenoid valve 26, and then pump clean water into the water outlet pipe 24 through the water pump 25. In this way, clean water is added into the mixing pot as a solvent through the water outlet pipe 24. At this point, the mixing head on the cement mortar mixer is used to stir and mix the materials to make mortar.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
