Technical Field

[0001] The utility model relates to the technical field of dry-mix mortar screening, in particular to dry-mix mortar production equipment. Background Art

[0002] Dry-mixed mortar is usually called hydraulic cement mixed mortar. It refers to a granular or powdery material made by physically mixing dried and sieved aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) in a certain proportion. It is transported to the construction site in bags or bulk and can be used directly after adding water and mixing. It is also called mortar dry powder, dry mix, and dry mixing powder. Some construction adhesives also belong to this category. Dry-mixed mortar is used in the construction industry in thin layers to perform bonding, cushioning, protection and decoration functions, and is widely used in construction and decoration projects.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 5 , the utility model provides a technical solution:

[0028] A dry-mix mortar production equipment comprises a vibrating screen body 1 and a driving motor 2 integrally connected thereto, a transmission member 3 is arranged on the outer surface of the vibrating screen body 1, the transmission member 3 is rotatably mounted on one side of the vibrating screen body 1, and is used in conjunction with the driving motor 2 to drive the vibrating screen body 1 to work, a drying mechanism 4 has the function of reducing dust flying after drying the material and is fixedly arranged above the vibrating screen body 1, a height limiting mechanism 5 can control the height of the deposited material and improve the function of the drying mechanism 4, and the height limiting mechanism 5 is fixedly connected to the vibrating screen body 1.

[0029] The transmission member 3 includes a first pulley 31 fixedly connected to the output end of the driving motor 2. A second pulley 32 is rotatably provided on one side of the vibration screen body 1 to drive the internal sieve plate of the vibration screen body 1. The first pulley 31 drives the second pulley 32 to rotate by means of a sleeve transmission belt 34. There are two transmission belts 34 in total, and the other pulley is sleeved on the outer surface of the second pulley 32 to drive the air intake plate 33 to rotate.

[0030] The drying mechanism 4 includes a heating pipe 41 and an ash suction pipe 42 fixedly installed on the top of the outer surface of the vibrating screen body 1. The heating pipe 41 and the ash suction pipe 42 are connected by two ventilation pipes 44. A swivel 43 is rotatably installed at one end of the heating pipe 41 close to the driving motor 2, and the swivel 43 is fixedly connected to the air inlet plate 33. The heating pipe 41 has the function of blowing hot air downward, and the ash suction pipe 42 has the function of absorbing dust.

[0031] The inner ring of the second pulley 32 is a roller and the outer ring is a ring used in conjunction with the first pulley 31 . The thickness of the roller is greater than that of the ring, and the excess part is sleeved with another transmission belt 34 used in conjunction with the air intake disc 33 .

[0032] A fan 431 is fixedly mounted on the inner surface of the rotating ring 43 , a blowing channel 432 is opened at the bottom of the heating tube 41 , and a heating plate is provided on the inner surface of the heating tube 41 .

[0033] A filter plate 421 is fixedly installed inside the ash suction pipe 42, an ash suction port 422 is provided at the bottom of the ash suction pipe 42, the filter plate 421 is tilted, a through hole for connecting two ventilation pipes 44 is provided inside the ash suction pipe 42, and one end of the tilted filter plate 421 is higher than one of the through holes, and the other end is lower than the other through hole.

[0034] By adopting the above technical solution, when the dry-mixed mortar is dried, the raw materials are first placed on the vibration screen body 1. As the driving motor 2 works, the vibration screen body 1 works through the transmission member 3. At this time, the driving motor 2 starts to rotate with the first pulley 31. The first pulley 31 rotates through one of the transmission belts 34 to rotate the outer ring of the second pulley 32, so that the raw materials in the vibration screen body 1 begin to move. At the same time, when the driving motor 2 works with the transmission member 3, the ring rotates and rotates together with the roller of the inner ring that rotates coaxially. Then the roller rotates with the air intake disk 33 through another transmission belt 34. Then the drying mechanism 4 works and the fan 431 on the inner wall rotates as the air intake disk 33 rotates. , wind enters the heating tube 41 from the air inlet disk 33, and blows the hot air onto the raw materials at the bottom through the blowing channel 432 at the bottom of the heating tube 41, and then the remaining warm air enters the ash suction tube 42 through the ventilation pipe 44. When the gas inside the ash suction tube 42 flows from one through hole to another through hole, the circulating gas causes the air pressure inside the ash suction tube 42 to be lower than the external air pressure, which will cause the external dust to be sucked into the ash suction tube 42 and filtered through the filter plate 421. When the gas enters the other through hole through one through hole, the gas will pass through the filter plate 421 and be filtered, leaving the dust, thereby completing the drying and ash suction operations of the raw materials. While realizing the operation of drying the raw materials, it can also effectively reduce the occurrence of dust flying.

[0035] Specifically, Figure 1 and Figure 2 As shown, the height limiting mechanism 5 includes rectangular blocks 51 welded on both sides of the vibrating screen body 1, a threaded hand rod 53 is rotatably installed on the rectangular block 51 on one side, and a slide rod 54 is slidably installed on the rectangular block 51 on the other side, and the same limiting plate 52 is slidably arranged between the threaded hand rod 53 and the slide rod 54, and the threaded hand rod 53 is threadedly connected to the limiting plate 52.

[0036] By adopting the above technical solution, when drying the raw materials, due to the accumulation of mortar, the mortar at the bottom cannot be completely dried because it cannot be dried. At this time, the threaded hand rod 53 can be manually rotated to move the limit plate 52 downward. At this time, when the limit plate 52 is moved downward after being threadedly connected to the hand rod, the limit plate 52 moves downward along the slide rod 54, moving the limit plate 52 downward, so that when the vibrating screen body 1 is working and moving with the raw materials, the height of the raw material accumulation is controlled, and the height of the raw material accumulation can be manually adjusted, thereby further improving the effect of drying the mortar.

[0037] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the inner diameter of the heating tube 41 is much larger than the inner diameters of the two ventilation tubes 44 .

[0038] By adopting the above technical solution, since the inner diameter of the heating tube 41 is much larger than the inner diameters of the two ventilation tubes 44, the gas entering the heating tube 41 cannot completely enter the ventilation tubes 44 at one time, and the remaining heated gas is blown out through the blowing channel 432 to dry the raw materials.

[0039] Working principle: When the dry-mixed mortar is dried, the raw materials are first placed on the vibrating screen body 1. As the driving motor 2 works, the vibrating screen body 1 is driven by the transmission member 3, so that the raw materials in the vibrating screen body 1 begin to move. At the same time, when the driving motor 2 drives the transmission member 3 to work, the drying mechanism 4 then works to complete the drying and dust absorption operations of the raw materials. While achieving the operation of drying the raw materials, it can also effectively reduce the occurrence of dust flying;

[0040] When drying the raw materials, due to the accumulation of mortar, the mortar at the bottom cannot be completely dried because it cannot be dried. At this time, the threaded hand rod 53 can be manually rotated to move the limit plate 52 downward, and the limit plate 52 can be moved downward, so that when the vibrating screen body 1 is working and moving with the raw materials, the height of the raw material accumulation can be controlled. The height of the raw material accumulation can be manually adjusted to further improve the effect of drying the mortar.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
