Description

Technical Field

[0001] The utility model relates to a wear-resistant machine mouth of a brick extruder and belongs to the technical field of brick extruders. Background Art

[0002] Brick extruder is a commonly used equipment for producing brick blanks. It squeezes the mud into mud strips with a certain cross-sectional shape, and then cuts the mud strips into the required brick blanks. At present, in the commonly used vacuum brick extruder, the mud is vacuum stirred and then extruded from the machine mouth by a propulsion device. Affected by multiple factors such as the plasticity, particle size, ratio, and moisture content of the raw materials, the viscosity of the mud is high and the extrusion force required is also large. Therefore, the friction between the mud and the machine mouth increases accordingly. In addition, the mud also contains a large amount of sand and gravel, so the machine mouth is easily worn and the service life of the machine mouth is reduced. In addition, when the water lubrication of the machine mouth is not good, the extruded mud strips are accompanied by spiral stratification, and the appearance quality of the produced brick blanks is poor and does not meet the relevant requirements.

[0009] The wear-resistant sheet is inclined toward the inner side of the machine mouth shell.

[0010] Furthermore, the pressing plate is provided with an adjusting screw for adjusting the length of the pressing handle protruding toward the inner side of the machine mouth shell and a clamping screw for clamping and fixing the pressing handle.

[0011] Further, the second lining plate includes: a primary plate and a secondary plate; the primary plate and the secondary plate are joined at an inclined surface, and the inclined direction of the inclined surface faces the mud discharge port of the machine mouth housing;

[0012] A notch is provided between the primary plate and the secondary plate, and the notch communicates with the groove.

[0013] Further, the first lining plate includes: a wear-resistant plate, and a backing plate is attached between the wear-resistant plate and the inner wall of the machine mouth housing; one end of the wear-resistant plate is lapped on the inner side of the second lining plate and there is a gap between them, and the gap communicates with the groove, and the lubricant enters the interior of the machine mouth housing through the gap.

[0029] As Figures 1-7 shown, this embodiment is implemented through the following technical solutions: A pressure plate 2 is provided at the mud outlet port of the machine mouth housing 1, and a scraping strip 3 is pressed between the pressure plate 2 and the machine mouth housing 1; A second lining plate 4 is attached to the inner wall of the machine mouth housing 1, and a first lining plate 5 is attached to the inner wall of the machine mouth housing 1 near its mud inlet port; A groove 101 for conveying lubricant is provided on the inner wall of the machine mouth housing 1, and the lubricant flows along the groove 101 into the interior of the machine mouth housing 1.

[0030] Specifically, the machine mouth housing 1 further includes: a liquid inlet 102 and a liquid outlet 103 communicating with the groove 101; The liquid inlet 102 is connected to the external lubrication system pipeline; A cleaning hole 105 communicating with the groove 101 is provided through the machine mouth housing 1, and a sealing plug 104 is provided on the cleaning hole 105.

[0031] In this embodiment, the lubricant is water; Water enters the groove 101 from the liquid inlet 102, part of the water enters the interior of the machine mouth housing 1 to lubricate the mud strip, and the remaining water flows out from the liquid outlet 103; When the groove 101 is blocked, the operator can remove the sealing plug 104 and observe and clean the groove 101 from the cleaning hole 105.

[0032] Specifically, the scraping strip 3 includes: a pressing handle 301, and a wear-resistant piece 302 is embedded on the inner side of the pressing handle 301, and the wear-resistant piece 302 faces the inner wall side of the machine mouth housing 1; The pressing handle 301 is pressed between the pressure plate 2 and the machine mouth housing 1; The wear-resistant piece 302 is inclined towards the inner side of the machine mouth housing 1.

[0033] Specifically, the pressure plate 2 is provided with an adjusting screw 201 for adjusting the length of the pressing handle 301 protruding towards the inner side of the machine mouth housing 1 and a clamping screw 202 for clamping and fixing the pressing handle 301.

[0034] The scraping strip 3 is used to adjust the size of the brick blank mud strip extruded from the machine mouth. The adjusting screw 201 pushes the scraping strip 3 to move, thereby changing the size of the mud outlet port of the machine mouth housing 1, so as to adjust the size of the extruded brick blank mud strip.

[0035] Specifically, the second lining plate 4 includes: a primary plate 401 and a secondary plate 402 ; the primary plate 401 and the secondary plate 402 are connected by an inclined surface, and the inclined surface is inclined toward the mud outlet port of the machine shell 1 .

[0036] A notch 403 is provided between the primary plate 401 and the secondary plate 402, and the notch 403 is connected to the groove 101. The lubricant flows from the notch 403 and the groove 101 to the inner wall of the second lining plate 4 to lubricate the surface of the extruded mud strip. The primary plate 401 and the secondary plate 402 are connected by an inclined surface to conform to the extrusion direction of the mud strip, so that the friction resistance of the mud strip is reduced, thereby avoiding the generation of spiral patterns in the mud strip during the extrusion process.

[0037] In this embodiment, the primary plate 401 and the secondary plate 402 are both made of a highly wear-resistant alloy material, and the angle of inclination of the inclined surface connecting the two is 30°. The first lining plate 5 is made of a wear-resistant material. The first lining plate 5 in the machine mouth shell 1 first contacts the coarsely mixed mud material, so it is more worn. Therefore, the wear resistance of the first lining plate 5 is stronger than that of the second lining plate 4.

[0038] Specifically, the first lining 5 includes: a wear-resistant plate 501, a pad 502 is attached between the wear-resistant plate 501 and the inner wall of the machine mouth shell 1; one end of the wear-resistant plate 501 is overlapped to the inner side of the second lining 4 and a gap 503 is left between the two, the gap 503 is connected to the groove 101, and the lubricant enters the interior of the machine mouth shell 1 through the gap 503.

[0039] The opening direction of the gap 503 is toward the extrusion direction of the clay material, so as to prevent the clay material from directly extruding into the gap 503 and causing blockage thereof. Figure 4 shown.

[0040] The specific use principle of the utility model is as follows:

[0041] The pushing device of the brick extruder delivers the mud into the machine mouth shell 1, and the mud is extruded and shaped by the machine mouth shell 1 to be transformed into brick mud strips. When the mud is extruded, the lubricant is simultaneously discharged from the machine mouth shell 1 to lubricate the mud to prevent the mud from generating spiral patterns due to insufficient lubrication. The first lining plate 5 and the second lining plate 4 are in direct contact with the mud to prevent the machine mouth shell 1 from being worn, thereby increasing the service life of the machine mouth shell 1.
