Description

Technical Field

[0001] This invention patent relates to the technical field of construction waste, and more specifically, to equipment for the resource utilization of construction waste. Background Technology

[0002] my country is currently in a period of rapid urbanization, and the construction and demolition of urban buildings generate a large amount of construction waste, including excavated soil, slag, and discarded materials. According to statistics, my country's construction waste exceeded 2 billion tons in 2022. Construction waste cannot be naturally degraded, and its long-term accumulation not only occupies a large amount of land but also easily causes serious pollution and ecological damage to soil, rivers, vegetation, and the atmosphere.

[0003] In the current technology, landfill is still the main method for treating construction waste. However, the capacity of construction waste disposal sites is limited and there is a lack of corresponding utilization measures, making it difficult to effectively treat construction waste. Summary of the Invention

[0004] The purpose of this invention is to provide equipment for the resource utilization of construction waste, aiming to solve the problem of the difficulty in effectively treating construction waste in the prior art.

[0005] The present invention is implemented as follows: a construction waste resource utilization equipment includes a jaw crusher for crushing construction waste into primary coarse material, a cone crusher for crushing primary coarse material into secondary coarse material, a single-layer vibrating screen for screening secondary coarse material into primary screening material, a multi-layer vibrating screen for screening primary screening material into powder material, a mixer for mixing powder material with cement and water respectively to form a mixture, and a table mold vibrating press for vibrating the mixture into brick blanks.

[0006] The jaw crusher has a primary crushing chamber with an open top. A feeding vibrator is provided behind the jaw crusher. The feeding vibrator has a vibrating belt that extends upward toward the jaw crusher. The vibrating belt extends above the primary crushing chamber and is suspended above the primary crushing chamber. The vibrating belt transmits the construction waste vibration to the upper part of the primary crushing chamber and it falls into the primary crushing chamber from top to bottom.

[0007] Furthermore, the primary crushing chamber is provided with an inclined fixed jaw plate and a movable movable jaw plate, the movable jaw plate and the fixed jaw plate being arranged at intervals facing each other; the fixed jaw plate has an inclined fixed surface, the movable jaw plate has a movable surface facing the fixed jaw plate, and there is a primary crushing interval for placing construction waste between the fixed surface and the movable surface.

[0008] Along the primary crushing interval from bottom to top, the fixed surface and the movable surface are inclined away from each other, and the vibration belt extends above the primary crushing interval and is arranged in a suspended manner above the primary crushing interval.

[0009] The upper part of the movable jaw plate is eccentrically connected to the drive rotor, and the lower part of the movable jaw plate is connected to an elastic structure. The elastic structure drives the lower part of the movable jaw plate to swing and reset downwards. When the drive rotor drives the movable jaw plate to rotate eccentrically up and down, the movable surface moves up and down towards or away from the fixed surface, crushing the construction waste placed in the primary crushing interval into primary coarse material.

[0010] Furthermore, a primary conveyor belt is provided between the jaw crusher and the cone crusher, and an iron remover is provided above the primary conveyor belt. The iron remover magnetically adsorbs iron impurities in the primary coarse material on the primary conveyor belt.

[0011] Furthermore, the cone crusher has a secondary crushing chamber, the outer periphery of the middle part of the secondary crushing chamber has a fixed crushing wall, the secondary crushing chamber is provided with a rotating cone, and the outer periphery of the rotating cone is provided with a rotating crushing wall;

[0012] Along the secondary crushing chamber from bottom to top, the fixed crushing wall and the rotating crushing wall are respectively arranged inwardly at an inward angle. A secondary crushing interval for accommodating primary coarse material is formed between the fixed crushing wall and the rotating crushing wall. The secondary crushing interval is arranged around the outer periphery of the rotating cone. The middle part of the fixed crushing wall protrudes towards the rotating crushing wall, forming a pointed, bent protrusion. The bent protrusion is arranged around the outer periphery of the rotating cone.

[0013] When the primary coarse material falls from top to bottom into the secondary crushing interval, the rotating cone rotates, and the primary coarse material is crushed by the compression of the fixed crushing wall and the rotating crushing wall to form the secondary coarse material.

[0014] Furthermore, the single-layer vibrating screen includes a single primary vibrating screen that is arranged inclined from top to bottom and vibrates to transmit secondary coarse material. The primary vibrating screen has primary screen holes. When the secondary coarse material is vibrated and transmitted from top to bottom on the primary vibrating screen, the secondary coarse material with a particle size smaller than the primary screen holes is screened out through the primary screen holes to form the primary screen material.

[0015] Furthermore, the multi-layer vibrating screen includes multiple secondary vibrating screens that are arranged at an angle and vibrate to transmit the primary screening material. The multiple secondary vibrating screens are arranged sequentially at intervals. Each secondary vibrating screen is provided with multiple secondary screen holes, and the secondary screen holes of the multiple secondary vibrating screens gradually decrease in size along the direction from top to bottom.

[0016] During the vibration transmission process of the primary screen material, the primary screen material passes through multiple secondary screen holes from top to bottom to form the powder.

[0017] Furthermore, the table mold vibratory press is equipped with a vibrating table, a support plate on the vibrating table, and the mold placed on the support plate. The mold has multiple mold cavities arranged in an array. The mold is equipped with a pressure head, and the pressure head has multiple corresponding lower pressure plates inserted into the mold cavities.

[0018] After the mixture is placed in the mold cavity, the pressure head moves toward the mold until multiple lower pressure plates press down on the mixture in the mold cavity from top to bottom. The lower pressure plates apply downward static pressure to the mixture. The vibration table drives the mold to vibrate up and down, vibrating and pressing the mixture in the mold cavity to form a brick blank.

[0019] Furthermore, the table vibratory press is equipped with a hopper for mixing materials, and the bottom of the hopper is provided with a discharge port; below the discharge port is a horizontally moving material distribution trolley, the material distribution trolley is provided with a material distribution chamber for mixing materials, the bottom of the material distribution chamber is arranged at an inclination, and the bottom of the material distribution trolley is provided with a strip-shaped material distribution opening.

[0020] When the mixed material in the hopper falls into the material distribution cavity through the discharge port, the material distribution trolley moves horizontally above the mold. During the process of the mixed material in the material distribution cavity falling into the mold cavity through the material distribution port, the vibrating table vibrates, thereby compacting the mixed material in the mold cavity through vibration.

[0021] Furthermore, the lower pressure plate is provided with a plurality of longitudinally arranged closed holes, the top of the closed holes being closed and the bottom of the closed holes penetrating the bottom of the lower pressure plate to form a bottom opening; the bottom of the lower pressure plate is covered with an elastic adhesive layer, the top of the adhesive layer having a plurality of elastic protrusions, the elastic protrusions extending upward from the bottom opening to the middle of the closed hole, thereby closing the bottom opening;

[0022] The adhesive layer has a horizontally arranged flat cavity, which is connected to the bottom of the lower pressure plate. The adhesive layer has an upper section above the flat cavity, and a plurality of elastic protrusions protrude from the upper section. The adhesive layer has a lower section below the flat cavity and an outer peripheral section surrounding the flat cavity. The top of the outer peripheral section abuts against the outer periphery of the upper section, and the bottom of the outer peripheral section abuts against the outer periphery of the lower section. The upper section, the outer peripheral section, and the lower section together form a closed flat cavity. A horizontally arranged rigid plate is embedded in the lower section.

[0023] When the lower pressure plate is inserted into the mold cavity, it presses against the mixture in the mold cavity from top to bottom. During the process of the vibration table driving the mold to vibrate, the adhesive layer reciprocates and deforms, the flat cavity simultaneously deforms and expands, and the multiple elastic protrusions expand and contract along the height direction of the closed hole.

[0024] Furthermore, the mixer is equipped with a rotating mixing drum, and the mixing drum is equipped with a mixing chamber; the outer periphery of the mixing chamber is equipped with a water tank for storing water and a cement tank for storing cement, and the outer side of the mixing drum is equipped with a vertically movable feeding hopper for storing powder, the feeding hopper placing the powder into the mixing chamber;

[0025] The water tank is connected to a water pipe, and the water pipe is equipped with a water pump. The water pump draws water from the water tank into the mixing chamber through the water pipe. The bottom of the cement tank is connected to a spiral cylinder, which is arranged at an angle from bottom to top. The spiral cylinder transfers cement from the cement tank to the mixing chamber.

[0026] Compared with existing technologies, the construction waste resource utilization equipment provided by this invention crushes and screens construction waste to form powder, then mixes the powder with cement and water to form a mixture, and uses a table-type vibratory press to compress the mixture into brick blanks. This method can effectively treat construction waste and has the following additional beneficial effects:

[0027] 1) Green and environmentally friendly: Using construction waste as the main raw material, it is crushed and mixed with cement and water to make non-fired finished bricks. The production process is green and pollution-free, which improves the comprehensive utilization rate of construction waste, solves the problem of "overload" of construction waste and pollution of the ecological environment, and promotes the sustainable development of the construction industry.

[0028] 2) Turning waste into treasure: Construction waste is crushed and screened into reusable powder. The powder is mixed with an appropriate amount of cement and water to form a mixture. The mixture is then pressed by a table mold vibrating press to form finished bricks, realizing the reuse and resource utilization of construction waste.

[0029] 3) High quality of finished bricks: The mixture is vibrated and pressed by a table mold vibratory press, which makes the mixture quick, uniform, compact and dense, forming finished bricks with a certain strength.

[0030] 4) High efficiency in construction waste treatment: Through modular design, various mechanical structures are organically combined, which is highly flexible and occupies less space on the overall working surface, forming a highly automated construction waste treatment platform, which significantly improves the efficiency of construction waste treatment.

[0042] Reference Figure 1-8 The image shows a preferred embodiment of the present invention.

[0043] The equipment for the resource utilization of construction waste includes a jaw crusher, a cone crusher 201, a single-layer vibrating screen, a multi-layer vibrating screen, a mixer, and a table-type vibrating press; along the processing flow of construction waste 103, the jaw crusher, cone crusher 201, single-layer vibrating screen, multi-layer vibrating screen, mixer, and table-type vibrating press are arranged in sequence.

[0044] The jaw crusher crushes construction waste 103 into primary coarse material 106. The cone crusher 201 crushes the primary coarse material 106 into secondary coarse material 206. The single-layer vibrating screen screens the secondary coarse material 206 into primary screening material. The multi-layer vibrating screen screens the primary screening material into powder through multiple layers. The mixer mixes the powder with cement and water to form a mixture 306. The table mold vibrating press presses the mixture 306 into brick blanks. When the brick blanks are removed from the mold 301, they are cured for a set time to form finished bricks.

[0045] The jaw crusher has a primary crushing chamber 100 with a top opening. A feeding vibrator is provided at the rear of the jaw crusher. The feeding vibrator has a vibrating belt that extends upward toward the jaw crusher. The vibrating belt extends above the primary crushing chamber 100 and is suspended above the primary crushing chamber 100. The vibrating belt vibrates and transmits the construction waste 103 to the upper part of the primary crushing chamber 100, and it falls into the primary crushing chamber 100 from top to bottom.

[0046] The aforementioned construction waste recycling equipment crushes and screens construction waste 103 to form powder, then mixes the powder with cement and water to form a mixture 306. A vibratory compactor is then used to press the mixture 306 into brick blanks. This effectively processes construction waste 103 and offers the following additional benefits:

[0047] 1) Green and environmentally friendly: Using construction waste 103 as the main raw material, after crushing, it is mixed with cement and water to make non-fired finished bricks. The production process is green and pollution-free, which improves the comprehensive utilization rate of construction waste 103, solves the problem of "overloading" of construction waste 103 and polluting the ecological environment, and promotes the sustainable development of the construction industry.

[0048] 2) Turning waste into treasure: Construction waste 103 is crushed and screened into reusable powder. The powder is mixed with an appropriate amount of cement and water to form a mixture 306. The mixture 306 is then pressed by a table mold vibrating press to form finished bricks, realizing the reuse and resource utilization of construction waste 103.

[0049] 3) High quality of finished bricks: The mixture 306 is vibrated and pressed by a table mold vibratory press, which makes the mixture 306 fast, uniform, compact and dense, forming finished bricks with a certain strength.

[0050] 4) High efficiency in construction waste 103 processing: Through modular design, various mechanical structures are organically combined, which is highly flexible and occupies less space on the overall working surface, forming a highly automated construction waste 103 processing platform, which significantly improves the processing efficiency of construction waste 103.

[0051] Construction waste 103 is a solid waste with relatively large block size and weight. It needs to be fed into the storage bin of the vibrating feeder by a loader. The vibrating feeder is responsible for feeding construction waste 103 from the storage bin evenly, regularly and continuously into the jaw crusher to prevent the jaw crusher from freezing due to uneven feeding.

[0052] By arranging a vibrating belt suspended above the primary crushing chamber 100, the construction waste 103 can fall evenly into the primary crushing chamber 100, preventing the jaw crusher from stalling due to uneven feeding.

[0053] Construction waste recycling equipment is suitable for the recycling and processing of construction waste (103 type), and for the production of finished bricks of various types and shapes. The finished bricks are mainly used for traditional paving materials, road construction, roadbed construction, park and greenway paving, urban riverbank stabilization and slope protection, and urban underground pipeline construction.

[0054] In this embodiment, the primary crushing chamber 100 is provided with an inclined fixed jaw plate 102 and a movable jaw plate 104, which are arranged facing each other. The fixed jaw plate 102 has an inclined fixed surface 1021, and the movable jaw plate 104 has a movable surface 1041 facing the fixed jaw plate. There is a primary crushing interval for placing construction waste 103 between the fixed surface 1021 and the movable surface 1041. Along the primary crushing interval from bottom to top, the fixed surface 1021 and the movable surface 1041 are inclined away from each other.

[0055] The upper part of the movable jaw plate 104 is eccentrically connected to the drive rotor 101, and the lower part of the movable jaw plate 104 is connected to an elastic structure 105. The elastic structure 105 drives the lower part of the movable jaw plate 104 to swing and reset the fixed jaw plate 102 downwards.

[0056] When the drive rotor 101 drives the movable jaw plate 104 to rotate eccentrically up and down, the movable surface 1041 moves back and forth up and down toward or away from the fixed surface 1021, crushing the construction waste 103 placed in the primary crushing interval into primary coarse material 106.

[0057] The jaw crusher can be the MCP-106J jaw crusher, with a total power of 136kw, a feeding capacity of 450t / h, and a maximum feed size of 560mm. The jaw crusher can crush hard objects with a compressive strength of up to 320Mpa.

[0058] A primary conveyor belt is provided between the jaw crusher and the cone crusher 201. An iron remover is provided above the primary conveyor belt. The iron remover uses magnetic attraction to adsorb iron impurities in the primary coarse material 106 on the primary conveyor belt, such as residual scrap steel bars and scrap iron wires, to ensure the quality of the primary coarse material 106.

[0059] In this embodiment, the cone crusher 201 has a secondary crushing chamber. The outer periphery of the middle part of the secondary crushing chamber has a fixed crushing wall 2011. The secondary crushing chamber is provided with an eccentrically rotating rotating cone head 202. The outer periphery of the rotating cone head 202 is provided with a rotating crushing wall 2021.

[0060] Along the secondary crushing chamber from bottom to top, the fixed crushing wall 2011 and the rotating crushing wall 2021 are respectively arranged inwardly at an inward angle. A secondary crushing interval 200 is formed between the fixed crushing wall 2011 and the rotating crushing wall. The secondary crushing interval 200 is arranged around the outer periphery of the rotating cone head 202. The middle part of the fixed crushing wall 2011 protrudes towards the rotating crushing wall, forming a pointed bent protrusion. The bent protrusion is arranged around the outer periphery of the rotating cone head 202.

[0061] When the primary coarse material 106 falls from top to bottom into the secondary crushing interval 200, the rotating cone head 202 rotates eccentrically, and the primary coarse material 106 is crushed by the compression of the fixed crushing wall 2011 and the rotating crushing wall to form the secondary coarse material 206.

[0062] The cone crusher 201 can be the MPC-300CS cone crusher 201, with a total power of 313kw, a processing capacity of 350t / h, and a maximum feed particle size of 210mm.

[0063] In this embodiment, the single-layer vibrating screen includes a single primary vibrating screen arranged inclined from top to bottom, and the primary vibrating screen has primary screen holes; when the secondary coarse material 206 is vibrating and transmitted from top to bottom on the primary vibrating screen, the secondary coarse material 206 with a particle size smaller than the primary screen holes is screened out through the primary screen holes to form primary screen material.

[0064] The bottom of the primary vibrating screen is connected to the cone crusher 201 via a return conveyor belt. The secondary coarse material 206 that does not pass through the primary screen holes falls onto the return conveyor belt and is transported back to the cone crusher 201 by the return conveyor belt.

[0065] In this embodiment, the multi-layer vibrating screen includes multiple secondary vibrating screens arranged sequentially in a vertical manner, and the secondary vibrating screens are arranged at an incline; the secondary vibrating screens are provided with multiple secondary screen holes, and the secondary screen holes of the multiple secondary vibrating screens gradually decrease in size along the direction from top to bottom.

[0066] During the vibration transmission of the primary screen material on the secondary vibrating screen, the primary screen material sequentially passes through the vibration screening of multiple secondary vibrating screens, passes through the secondary screen holes, and forms powder.

[0067] Multi-layer vibrating screens can perform multi-stage screening of primary materials, and the materials screened at each stage can be transferred accordingly, such as screening crushed stone first, then medium sand, and finally powder. Using a vibrating motor as the excitation source eliminates transmission losses, resulting in stronger excitation force and larger amplitude, allowing the primary material to be rapidly screened stage by stage under vibration.

[0068] In this embodiment, the table mold vibratory press is provided with a vibrating table 300, a support plate 302 on the vibrating table 300, a mold 301 placed on the support plate 302, a plurality of mold cavities in the mold 301, the plurality of mold cavities being arranged in an array; a pressure head 400 is provided on the mold 301, and a plurality of lower pressure plates 401 corresponding to be inserted into the mold cavities are provided on the pressure head 400.

[0069] After the mixture 306 is placed in multiple mold cavities, the pressure head 400 moves toward the mold 301 until multiple lower pressure plates 401 press down on the mixture 306 in the mold cavity from top to bottom. The lower pressure plates 401 apply downward static pressure to the mixture 306. The vibration table 300 drives the mold 301 to vibrate up and down, and vibrates and presses the mixture 306 in the mold cavity so that the mixture 306 in the mold cavity forms a brick blank.

[0070] The lower pressure plate 401 applies static pressure to the mixture 306 from top to bottom, while the vibration table 300 applies dynamic vibration force to the mixture 306. While vibrating up and down, it also vibrates horizontally, thereby making the mixture 306 in the mold cavity more compact.

[0071] In this embodiment, the table vibratory press is equipped with a hopper 603 for storing the mixing material 306, and the bottom of the hopper 603 is provided with a discharge port; below the discharge port is a horizontally movable material distribution trolley 600, and the material distribution trolley 600 is provided with a material distribution cavity 601 for storing the mixing material 306. The bottom of the material distribution cavity 601 is arranged at an inclination, and the bottom of the material distribution trolley 600 is provided with a strip-shaped material distribution port 602.

[0072] When the mixed material 306 in the hopper 603 falls into the feeding cavity 601 through the discharge port, the feeding trolley 600 moves horizontally above the mold 301. As the mixed material 306 in the feeding cavity 601 falls into the mold cavity through the feeding port 602, the vibrating table 300 vibrates, compacting the mixed material 306 in the mold cavity through vibration. During the feeding process, the vibrating table 300 vibrates horizontally, and the mixed material 306 is subjected to impact and oscillation, falling evenly into the mold cavity of the mold 301 and initially compacting it.

[0073] Before the material is laid, the feeding machine sends the pallet 302 to the bottom of the mold 301. After the mixed material 306 is vibrated and formed into brick blanks, the brick conveyor frame drives the pallet 302 to transport the brick blanks to the stacking machine.

[0074] In this embodiment, after the brick blank has been formed in the mold cavity for a set time, the mold 301 and the pressure head 400 move upward away from the support plate 302, and the upward movement speed of the pressure head 400 is lower than the upward movement speed of the mold 301. Multiple lower pressure plates 401 detach the brick blank from the mold cavity, and the support plate 302 carries multiple brick blanks to a set position for curing.

[0075] The brick blanks are cured naturally, reaching 100% strength in 28 days. The curing time is about 24 hours. Only after curing can the brick blanks be moved or removed from the pallet 302. The stacking height of the brick blanks should not exceed 1.3m.

[0076] In this embodiment, the lower pressure plate 401 is provided with a plurality of longitudinally arranged closed holes 700. The top of the closed holes 700 is closed, and the bottom of the closed holes 700 penetrates the bottom of the lower pressure plate 401 to form a bottom opening. The bottom of the lower pressure plate 401 is covered with an elastic adhesive layer. The top of the adhesive layer has a plurality of elastic protrusions 706. The elastic protrusions 706 extend upward from the bottom opening to the middle of the closed holes 700 to close the bottom opening.

[0077] When the adhesive layer is squeezed upwards, the elastic protrusion 706 moves upwards in the closed hole 700, compressing the air in the closed hole 700 and increasing the air pressure in the closed hole 700. When the elastic protrusion 706 moves downwards in the closed hole 700 to reset, the space in the closed hole 700 increases and the air pressure decreases.

[0078] The adhesive layer has a horizontally arranged flat cavity 704, which is arranged with the bottom of the lower pressure plate 401. The adhesive layer has an upper section 701 located above the flat cavity 704, and a plurality of elastic protrusions 706 protruding from the upper section 701. The adhesive layer has a lower section 703 located below the flat cavity 704 and an outer peripheral section 702 surrounding the outer periphery of the flat cavity 704. The top of the outer peripheral section 702 is connected to the outer periphery of the upper section 701, and the bottom of the outer peripheral section 702 is connected to the outer periphery of the lower section 703. The upper section 701, the outer peripheral section 702, and the lower section 703 enclose and form a closed flat cavity 704. A horizontally arranged rigid plate 705 is embedded in the lower section 703.

[0079] When the pressure plate 401 is inserted into the mold cavity, it presses against the mixture 306 in the mold cavity from top to bottom. During the vibration of the mold 301 driven by the vibration table 300, the adhesive layer is flattened and deformed back and forth. The flat cavity 704 is flattened and deformed up and down simultaneously. Multiple elastic protrusions 706 are stretched and deformed along the height direction of the closed hole 700.

[0080] When the adhesive layer is subjected to upward pressure, the lower section 703, constrained by the cardboard, maintains a horizontal pressure state. The outer peripheral section 702 and the upper section 701 deform flatly. When the flat cavity 704 is compressed and the elastic protrusion 706 is embedded in the closed hole 700 to a greater depth, the adhesive layer reverses and drives the lower section 703 to elastically squeeze the mixture 306 downward. Combined with the upward vibration of the vibration table 300, the mixture 306 is clamped and vibrated in opposite directions, resulting in a more compact mixture 306 in the mold cavity.

[0081] In this embodiment, the mixer is provided with a rotating mixing drum 500, and the mixing drum 500 is provided with a mixing chamber; a water tank 503 for storing water and a cement tank 501 for storing cement are provided on the outer periphery of the mixing chamber; a feeding hopper 603 for storing powder is provided on the outer side of the mixing drum 500, which moves up and down and places powder in the mixing chamber.

[0082] Water tank 503 is connected to a water pipe, and the water pipe is equipped with a water pump. The water pump draws the water in water tank 503 into the mixing chamber through the water pipe. Cement tank 501 is connected to a spiral cylinder 502 at the bottom. The spiral cylinder 502 is arranged at an angle from bottom to top and transfers the cement in cement tank 501 into the mixing chamber.

[0083] The measured powder and cement are placed in a mixer. After the powder and cement are mixed and stirred in the mixer for a set time, the measured water is injected into the mixer. The water is then mixed and stirred with the mixed powder and cement for a set time to form a mixture 306.

[0084] Powder, cement, and water are mixed in a specific ratio to form a mixture 306. When cement comes into contact with water, it reacts to form hydrates and a paste, which carries the powder. As the hydration reaction of the cement continues, the water gradually decreases, the paste loses its plasticity and begins to solidify, and over time, crystals are formed.

[0085] The colloids and crystals intertwine to form a network. The colloids act as a binder, binding the powder together, while the powder and crystals act as a framework. All three grow together and are tightly bonded. After a certain period of curing, the strength of the cement gradually increases. Its setting and hardening process promotes the separation of the materials into solidified and strong particles, forming a dense and robust solid.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The table vibratory press is equipped with a hopper for mixing materials, and the bottom of the hopper is provided with a discharge port; below the discharge port is a horizontally moving material distribution trolley, and the material distribution trolley is provided with a material distribution chamber for mixing materials, the bottom of the material distribution chamber is arranged at an inclination, and the bottom of the material distribution trolley is provided with a strip-shaped material distribution opening. When the mixed material in the hopper falls into the material distribution cavity through the discharge port, the material distribution trolley moves horizontally above the mold. During the process of the mixed material in the material distribution cavity falling into the mold cavity through the material distribution port, the vibrating table vibrates, and the mixed material in the mold cavity is compacted by vibration. The lower pressure plate has multiple longitudinally arranged closed holes. The top of the closed holes is closed, and the bottom of the closed holes penetrates the bottom of the lower pressure plate to form a bottom opening. The bottom of the lower pressure plate is covered with an elastic adhesive layer. The top of the adhesive layer has multiple elastic protrusions. The elastic protrusions extend upward from the bottom opening to the middle of the closed hole to close the bottom opening. The adhesive layer has a horizontally arranged flat cavity, which is connected to the bottom of the lower pressure plate. The adhesive layer has an upper section above the flat cavity, and a plurality of elastic protrusions protrude from the upper section. The adhesive layer has a lower section below the flat cavity and an outer peripheral section surrounding the flat cavity. The top of the outer peripheral section abuts against the outer periphery of the upper section, and the bottom of the outer peripheral section abuts against the outer periphery of the lower section. The upper section, the outer peripheral section, and the lower section together form a closed flat cavity. A horizontally arranged rigid plate is embedded in the lower section. When the lower pressure plate is inserted into the mold cavity, it presses against the mixture in the mold cavity from top to bottom. During the process of the vibration table driving the mold to vibrate, the adhesive layer is flattened and deformed back and forth, the flat cavity is flattened and deformed synchronously, and the multiple elastic protrusions are stretched and deformed along the height direction of the closed hole. The single-layer vibrating screen includes a single primary vibrating screen that is inclined from top to bottom and vibrates to transmit secondary coarse material. The primary vibrating screen has primary screen holes. When the secondary coarse material is vibrated and transmitted from top to bottom on the primary vibrating screen, the secondary coarse material with a particle size smaller than the primary screen holes is screened out through the primary screen holes to form the primary screen material. The multi-layer vibrating screen includes multiple secondary vibrating screens that are arranged at an angle and vibrate to transmit the primary screening material. The multiple secondary vibrating screens are arranged sequentially at intervals. Each secondary vibrating screen is provided with multiple secondary screen holes, which gradually decrease in size along the direction from top to bottom. During the vibration transmission process of the primary screen material, the primary screen material passes through multiple secondary screen holes from top to bottom to form the powder.
