Description

Technical Field

[0001] The utility model belongs to the technical field of self-leveling cement production, in particular to a screening and filtering device for producing microcrystalline self-leveling cement. Background Art

[0002] Microcrystalline self-leveling cement is a high-tech, environmentally friendly product with complex technical processes. It is a dry-mixed powder composed of multiple active ingredients that can be used on-site by mixing with water. Simply spreading it with a scraper creates a highly flat surface. Self-leveling cement hardens quickly, allowing pedestrians to walk on it after 4-5 hours, and surface construction (such as wood flooring and diamond board installation) can begin after 24 hours. Its speed and ease of application are unmatched by traditional manual leveling.

[0003] When producing microcrystalline self-leveling cement, the microcrystalline self-leveling cement powder needs to be screened through a screening device, and the larger particles need to be screened out before the smaller powder particles are put into production. When the existing screening device is in use, the built-in sieve holes can only screen out particles of a specific size. In actual use, when it is necessary to control the size of the screened particles according to construction needs, it is not easy to adjust the size of the built-in sieve holes, which will affect the final molding quality of the self-leveling cement.

[0004] To this end, we provide a microcrystalline self-leveling cement production screening and filtration device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a screening and filtering device for the production of microcrystalline self-leveling cement, in which a movable sleeve is driven to move by the rotation of a screw rod, and the movable sleeve cooperates with a first hinge rod to drive the sliding sleeve to move on the screening barrel, and the position between the first discharge hole and the second discharge hole changes. The auger will transport the particles in the barrel, and when passing through the first discharge hole and the second discharge hole, the particles will fall through the gap between the two. The size of the screening particles can be adjusted by adjusting the spacing.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a screening and filtering device for producing microcrystalline self-leveling cement, comprising a main frame; a slide groove is provided on the side of the main frame, an adjusting member is installed in the slide groove, and the adjusting member comprises two connecting plates fixedly connected to the surface of the main frame, a screw rod is rotatably connected through the two connecting plates, a first motor is bolted to the side of the connecting plate, and the output end of the first motor is fixedly connected to the screw rod; a movable sleeve is threadedly connected to the screw rod, a first hinge rod is hinged on the movable sleeve, the end of the first hinge rod is hinged to an articulated seat, a sliding sleeve is fixedly connected to the bottom surface of the articulated seat, a screening barrel is provided in the main frame, and the sliding sleeve is slidably connected to the screening barrel.

[0008] The present invention is further configured such that a plurality of sliders are slidably connected to the slide groove, a second hinge rod is hinged to each of the sliders, and a connecting rod is hinged to the end of the second hinge rod.

[0009] The present invention is further configured such that a plurality of insertion holes are evenly opened on the slide groove, and each side of the slider is slidably connected with an insertion rod, and each insertion rod is respectively plugged into the corresponding insertion hole.

[0010] The utility model is further configured such that each of the connecting rods is fixedly connected to the screening barrel, a rotating rod is rotatably connected through the screening barrel, and an auger is fixedly connected to the peripheral side of the rotating rod.

[0011] The present invention is further configured such that a second motor is fixedly connected to an eccentric portion of a side surface of the screening barrel, an output end of the second motor is fixedly connected to a rotating shaft, and an end portion of the rotating shaft is fixedly connected to a first sprocket.

[0012] The present invention is further configured such that the end of the rotating rod is fixedly connected to a second sprocket, and a chain is provided for transmission between the first sprocket and the second sprocket.

[0013] The utility model is further configured such that a feed port is fixedly connected to one end of the side surface of the screening barrel, and a discharge port is fixedly connected to the other end of the side surface of the screening barrel.

[0014] The utility model is further configured such that a plurality of first discharge holes are provided on the peripheral side of the screening barrel, and a second discharge hole corresponding to the first discharge holes is provided on the peripheral side of the sliding sleeve.

[0015] The utility model has the following beneficial effects:

[0016] 1. When the utility model is in use, the first motor drives the screw to rotate, and the movable sleeve on the screw moves through the first hinge rod to drive the sliding sleeve to move on the screening barrel. The positions of the first discharge hole and the second discharge hole change, and the screening size of the powder particles entering the screening barrel can be adjusted.

[0017] 2. When the utility model is in use, the angle of the screening barrel can be adjusted by sliding the slider on the slide groove and inserting the rod into the corresponding socket.

The first hinge rod 8 pulls the bottom sliding sleeve 10 to move on the screening barrel 15. The first discharge hole 27 and the second discharge hole 26 are initially in the overlapping state. After moving, the position between the first discharge hole 27 and the second discharge hole 26 moves, and the size of the falling particles can be adjusted during screening. Specific embodiment 2
