Description

Technical Field

[0001] The utility model relates to the technical field of plaster mortar preparation, in particular to an environmentally friendly mixing device for preparing plaster mortar. Background Art

[0002] Plaster mortar is a general term for a type of mortar that is applied to the building base to provide protection. Depending on the operation, plaster mortar is divided into on-site mixing mortar and premixed dry powder plaster mortar. Premixed dry powder plaster mortar is a type of commercial mortar, among which dry powder plaster mortar is made of cement, filler, aggregate and a variety of functional admixtures. Plaster mortars with different functions are used for different wall substrates. For example, there are plaster mortars suitable for lightweight walls such as aerated concrete blocks, fly ash blocks, and ceramsite bricks, and there are plaster mortars that are directly scraped on the surface of concrete shear walls.

[0003] The utility model application number CN202222637884.4 discloses an environmentally friendly mixing device for preparing plaster mortar. The enclosed feeding mechanism prevents dust generated during loading from spreading outside the mixing tank when the plaster mortar mixture is transported and delivered to the mixing tank, preventing environmental pollution and preventing workers from inhaling excessive dust, making it more environmentally friendly. The cleaning mechanism cleans the mixing tank and agitator to prevent it from affecting the subsequent mixing of other plaster mortars.

[0004] The above device is loaded through a loading box, and the cement raw materials directly enter the mixing tank. The cement raw materials are easy to agglomerate when stored in bags for a long time, and the agglomerated cement cannot be broken. Direct mixing of the agglomerated cement is likely to cause uneven mixing, affecting the mixing quality of the plaster mortar and reducing the mixing effect. The inside of the mixing tank is cleaned by flushing, and the mortar is easy to adhere to the inner wall of the mixing tank, which is not easy to flush off and the cleaning is not thorough.

[0005] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility Model Content

[0006] The purpose of the utility model is to solve the above problems and to design an environmentally friendly mixing device for preparing plaster mortar.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The top of the mixing drum is provided with a filter screen, and the filter screen is slidably connected to the filter screen by the fixing rod.

[0009] Furthermore, a stirring motor is installed at the center of the top of the mixing barrel, and a stirring shaft is installed at the output end of the stirring motor. The stirring shaft extends into the mixing barrel, and a stirring frame is installed on the stirring shaft. The stirring frame is provided with multiple stirring rods, and a discharge pipe is provided on one side of the bottom of the mixing barrel, and a discharge valve is provided on the discharge pipe.

[0010] Furthermore, an annular pipe is installed above the interior of the mixing barrel, water outlet holes are provided around the bottom of the annular pipe, a first liquid inlet pipe is provided on the top of the mixing barrel, the first liquid inlet pipe is connected to the annular pipe, and a second liquid inlet pipe is provided on the top of the mixing barrel.

[0011] Furthermore, scrapers are installed on both sides and the bottom of the stirring frame, and the scrapers are in contact with the inner wall of the mixing barrel.

[0012] Furthermore, fixed side plates are installed on both sides of the surface and bottom of the filter screen plate, and the fixed side plates are slidingly connected to the side walls of the fixed support plate. One end of the shock-absorbing spring is connected to the fixed support plate, and the other end of the shock-absorbing spring is connected to the filter screen plate.

[0013] Furthermore, the water outlet is arranged obliquely, and the outlet of the water outlet faces the inner wall of the mixing barrel.

[0014] Compared with the existing technology, this technical solution has the following beneficial effects:

[0015] The filter screen moves up and down to vibrate the cement, and the lumps of cement come into contact with the conical spikes, which break them up. This prevents the filter screen from being blocked, and qualified cement passes through the filter holes into the mixing barrel, avoiding the presence of lumps of cement during mixing, thereby improving the quality of the mortar and the mixing efficiency.

[0016] Water is flushed onto the inner wall of the mixing barrel through the water outlet, and the mortar adhering to the inner wall of the mixing barrel can be scraped off by the scraper to prevent the mortar from hardening on the inner wall of the mixing barrel. The inner wall of the mixing barrel can be flushed to facilitate the mixing of other plaster mortars and improve the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS
