Description

Technical Field

[0001] This utility model relates to the field of raw material screening technology, and in particular to a screening and processing device for building material raw materials. Background Technology

[0002] Building material raw material screening and processing equipment is a key piece of equipment used to separate raw materials of different particle sizes in the process of building material processing. It is widely used in the classification and processing of materials such as sand and gravel, concrete aggregates, and mineral powders.

[0003] The existing method uses the screen inside the equipment to swing back and forth, which can play a certain screening role, but it does not have a vibration effect. The screening is not sufficient, and a certain amount of raw material can easily accumulate on the screen, causing blockage and requiring frequent cleaning. At the same time, after the screen has been used for a long time, a lot of larger particles of raw material will accumulate, which can also cause blockage. In this case, the raw material on the screen is usually manually cleaned out periodically before it can be reused. The operation is relatively cumbersome and needs to be carried out inside the equipment. The internal space of the equipment is small, making the operation extremely inconvenient. An existing patent (publication number: CN210358029U) discloses a multifunctional screening device for building material raw materials, relating to the technical field of building material processing equipment. This utility model includes a housing, a screening box inside the housing, a soft screen on top of the screening box, a discharge hopper located below the soft screen inside the screening box, a reciprocating drive mechanism at the bottom of the housing that can drive the screening box to reciprocate, a baffle cover detachably connected to the top of the screening box surrounding the soft screen, at least two movable rods connected to both sides of the screening box, and sleeves on the side walls of the housing that cooperate with the corresponding movable rods. The movable rods can slide left and right within the sleeves, and each sleeve contains a compression spring A that can contact the movable rod. This utility model has the advantages of simple structure, added vibration function, and more thorough screening.

[0004] To address the aforementioned issues, existing patents have provided solutions. However, existing building material raw material screening devices lack a structure for drying the raw materials before screening, which causes damp materials to easily clump together on the screen, clogging the screen holes and reducing screening efficiency.

[0005] Therefore, a screening and processing device for building material raw materials is proposed. Utility Model Content

[0018] 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.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: A building material raw material screening and processing device includes a screening machine body 1. A drying mechanism 2 is welded to the surface of the top feed inlet of the screening machine body 1. The drying mechanism 2 includes a heat insulation shell 21, two heating rings 22, several air outlet pipes 23, an accelerating electric fan 24, a drying pipe 25, and several ventilation holes 26. The heat insulation shell 21 is welded to the surface of the top feed inlet of the screening machine body 1. The heating rings 22 are installed at the top and bottom of the inner side of the heat insulation shell 21. The bottom of the air outlet pipe 23 is fixedly connected to the top of the heat insulation shell 21. The accelerating electric fan 24 is installed at the top of the inner side of the air outlet pipe 23. The drying pipe 25 is welded to the inner side of the heat insulation shell 21. The bottom of the drying pipe 25 is welded to the top of the top feed inlet of the screening machine body 1. The top of the air outlet pipe 23 passes through and is fixedly connected to the bottom of the inner side of the drying pipe 25. An auxiliary mechanism 3 is welded to the top of the drying pipe 25. The ventilation holes 26 are opened at the bottom of the surface of the heat insulation shell 21.

[0020] In this embodiment: the screening machine body 1 provides the main space for raw material screening, and a screen and vibration mechanism are installed inside to achieve the grading of materials of different particle sizes. The top feed inlet is welded to the drying mechanism 2 to form an integrated structure from drying to screening, reducing the equipment footprint and material transfer loss. The heat insulation shell 21 reduces the heat loss of the heating ring 22 to the outside. At the same time, it can support and limit the heating ring 22, the air outlet pipe 23, the drying pipe 25 and the ventilation hole 26. The heating ring 22 is linked with the PLC controller 35. The air inside the heat insulation tube shell 21 is heated, and the power can be adjusted according to the feedback of the temperature sensor 34 to avoid overheating and energy waste. The air outlet pipe 23 sends the air heated by the heating ring 22 into the drying pipe 25, and the electric fan 24 accelerates the convection heat exchange between the hot air and the material. The drying pipe 25 can guide the hot air to flow upward to dry the raw materials at the top of the interceptor plate 32. The ventilation holes 26 are opened at the bottom of the heat insulation tube shell 21, and there are 16 holes to ensure that the cold air from the outside enters the heating area evenly, forming a closed loop from air inlet to heating to air outlet.

[0021] Specifically, such as Figure 4 As shown, the auxiliary mechanism 3 includes a connecting plate 31, an intercepting plate 32, a feed pipe 33, a temperature sensor 34, and a PLC controller 35. The connecting plate 31 is welded to the top of the drying pipe 25.

[0022] Specifically, such as Figure 4 As shown, the interceptor plate 32 is slidably connected to the inner side of the connecting plate 31, the feed pipe 33 is welded to the top of the connecting plate 31, and the temperature sensor 34 is installed on the right side of the feed pipe 33.

[0023] Specifically, such as Figure 4 As shown, the detection end of the temperature sensor 34 on the left side extends through and into the inside of the feed pipe 33, and the PLC controller 35 is installed on the front side of the screening machine body 1.

[0024] In this embodiment: the connecting plate 31 supports the feed pipe 33 and the intercepting plate 32. The intercepting plate 32 can intercept the raw material and prevent it from entering the screening machine body 1. The feed pipe 33 makes it convenient for the operator to put the raw material in. The temperature sensor 34 transmits the temperature signal to the PLC controller 35, which adjusts the heating ring 22 and the electric fan in a linkage manner to realize automated temperature control. The PLC controller 35 automatically adjusts the heating power and fan speed according to the feedback from the temperature sensor 34.

[0025] Specifically, such as Figure 5 As shown, a reinforcing rod 4 is welded to the chamfer at the bottom of the connecting plate 31, and the surface of the reinforcing rod 4 is coated with an anti-corrosion coating.

[0026] Specifically, such as Figure 5 As shown, an interception filter 5 is fixedly connected to the inner side of the interception plate 32, and the surface of the interception filter 5 is coated with an anti-corrosion coating.

[0027] In this embodiment: by setting a reinforcing rod 4, deformation of the connecting plate 31 is prevented from being caused by long-term material impact; by setting an anti-corrosion coating, the acidic substances in the building material dust are resisted, extending its service life; by setting an intercepting filter 5, the raw materials can be intercepted, and hot air can pass through the intercepting filter 5 and continue to flow upward to contact the raw materials, thereby removing the moisture from the raw materials; by setting an anti-corrosion coating, the intercepting filter 5 is prevented from being in contact with the raw materials for a long time, thus avoiding corrosion and rust damage.

[0028] Specifically, such as Figure 3 As shown, a dustproof net 6 is fixedly connected to the top of the inner side of the air outlet pipe 23, and the surface of the dustproof net 6 is coated with anti-corrosion paint.

[0029] Specifically, such as Figure 5 As shown, a heat insulation pull plate 7 is welded to the left side of the interceptor plate 32, and the surface of the heat insulation pull plate 7 is engraved with anti-slip texture.

[0030] In this embodiment: by setting a dustproof net 6, fine powder raised during the drying process is prevented from entering the accelerating electric fan 24; by setting an anti-corrosion coating, oxidation and corrosion in a high-temperature and humid environment are resisted; by setting a heat insulation pull plate 7, burns to the operator are prevented; and by setting an anti-slip texture, the friction between the operator's hand and the heat insulation pull plate 7 is increased.

[0031] Working principle: First, the operator feeds the raw material into the feed pipe 33. The raw material falls onto the interceptor plate 32, which, in conjunction with the interceptor filter 5, temporarily blocks the raw material, preventing it from directly entering the screening machine body 1, thus creating conditions for the drying process. Next, the PLC controller 35 starts, and the heating ring 22 begins to work, heating the air inside the heat insulation shell 21. Simultaneously, outside cold air enters evenly through the ventilation holes 26 at the bottom of the heat insulation shell 21, mixing with the heat generated by the heating ring 22 to form hot air. Then, the electric fan 24 accelerates its operation, sending the hot air heated by the heating ring 22 into the drying pipe 25 through the air outlet pipe 23. Afterward, the drying pipe 25 guides the hot air upward, and the hot air passes through the interceptor... The filter screen 5 comes into full contact with the raw material, removing moisture and drying it. During this process, the temperature sensor 34, installed on the right side of the feed pipe 33, monitors the temperature in real time and transmits the temperature signal to the PLC controller 35. Based on the information from the temperature sensor 34, the PLC controller 35 automatically adjusts the heating power of the heating ring 22 and the speed of the acceleration fan 24 to achieve automated temperature control. Finally, after the raw material is dried, the operator pulls the heat insulation pull plate 7 on the left side of the interceptor plate 32 to remove the interception of the raw material, which then falls into the screening machine body 1. Using the screen and vibration mechanism, the material of different particle sizes is graded, completing the integrated process from drying to screening.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
