Description

Technical Field

[0001] This utility model belongs to the technical field of mixing devices, and in particular relates to a fire door waste core material mixer that is easy to clean. Background Technology

[0002] Traditionally, cement core boards in the door manufacturing industry are mostly recycled through crushing, resulting in high overall waste recycling costs, large waste storage space requirements, and significant dust pollution. Therefore, a new process has emerged that utilizes waste core boards, fly ash, coal slag, coal gangue, etc. (one or more of these raw materials) as the main raw materials, adding coagulants and trace chemical additives in specific proportions, followed by high-pressure pressing to rapidly harden the bricks. This process is tailored to local conditions, utilizes locally sourced materials, reduces waste disposal costs, saves on labor and space costs, improves production efficiency, and eliminates environmental pollution.

[0003] However, during the processing, a mixing device is needed to fully mix the added raw materials, coagulants, water, etc., so that the particle size, humidity, and degree of mixing can reach the optimal plastic state.

[0004] Chinese Patent CN106393427A discloses a mixer for fireproof board production. The disclosed design includes: "a feeding mechanism, a mixing mechanism, and a fixed frame; the feeding mechanism includes a feeding hopper, a feeding pipe, a weighing hopper, and a mixing tank; the feeding hopper and the weighing hopper are connected via the feeding pipe; the weighing hopper is connected to the mixing tank; a first pneumatic valve is provided at the connection between the mixing tank and the weighing hopper; a second pneumatic valve is provided at the bottom of the mixing tank; the mixing tank is fixedly mounted on the fixed frame; a water tank is also fixedly mounted on the fixed frame." This design achieves integrated mixing and unloading operations, and allows for separate control of the raw material quantity during mixing and stirring, ensuring thorough mixing and stirring of the raw materials.

[0005] However, the above solution still has some shortcomings: 1. The mixing mechanism in the mixing chamber is difficult to mix the mixture adhering to the chamber wall, resulting in uneven mixing. If the mixture on the chamber wall is not scraped for a long time, it is easy for the mixture to solidify on the chamber wall, making it difficult to clean later; 2. The mixing mechanism lacks a cleaning mechanism, making it difficult to clean the inner top wall of the mixing chamber.

[0006] Therefore, a fire door waste core material mixer that is easy to clean reduces the adhesion of the mixture to the silo wall and is easy to clean. Utility Model Content

[0007] The purpose of this invention is to provide a fire door waste core material mixer that is easy to clean, so as to solve the problems existing in the background art.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] A fire door waste core material mixer that is easy to clean includes a mounting frame, a dual-shaft mixing chamber, a waste core material chamber, a cement chamber, and a water metering chamber. The dual-shaft mixing chamber is fixed on the mounting frame. The waste core material chamber, cement chamber, and water metering chamber are connected to the mounting frame and fixed above the dual-shaft mixing chamber. A cleaning assembly is provided above the dual-shaft mixing chamber. The cleaning assembly includes, from top to bottom, a telescopic cylinder, a mounting plate, and a spray head. The mounting plate is slidably connected to a column on the mounting frame. The mounting plate and the spray head move up and down through the telescopic cylinder.

[0010] The dual-shaft mixing chamber includes a chamber body, a chamber cover, and a mixing shaft. The mixing shaft is provided with multiple inclined scrapers that fit against the inner wall of the chamber. The chamber cover is provided with through holes corresponding to the positions of the spray heads, and plugs are provided in the through holes.

[0011] Furthermore, the plug has a frustum structure, with the small end of the plug located inside the through hole and the large end of the plug located inside the compartment body. A tension spring is provided between the large end of the plug and the lower end face of the compartment cover.

[0012] Furthermore, the lower end of the spray head is provided with an abutment post and a nozzle. The abutment post is located at the center of the lower end of the spray head, and a plurality of nozzles are arranged in a circumferential array outside the abutment post. The nozzles and the abutment post are arranged at an angle, and the lower end of the abutment post extends out of the nozzle.

[0013] Furthermore, a plurality of the spray head arrays are arranged below the mounting plate, wherein the outer diameter of the spray head is smaller than the inner diameter of the through hole, and the length of the spray head is greater than the depth of the through hole.

[0014] Furthermore, the cylinder body of the telescopic cylinder is connected to the top frame of the mounting bracket, the piston rod of the telescopic cylinder is connected to the mounting plate, the mounting plate is located below the discharge ports of the waste core material silo, cement silo and water metering silo, the mounting plate and the silo cover are provided with openings corresponding to the discharge ports of the waste core material silo, cement silo and water metering silo, and the silo cover is a center-opening structure.

Detailed Implementation

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] See Figures 1-7 This utility model provides a technical solution:

[0032] like Figures 1-2 As shown, a fire door waste core material mixer that is easy to clean includes a mounting frame 1, a dual-shaft mixing chamber 2, a waste core material chamber 3, a cement chamber 4, and a water metering chamber 5. The dual-shaft mixing chamber 2 is fixed on the mounting frame 1, and the waste core material chamber 3, cement chamber 4, and water metering chamber 5 are connected to the mounting frame 1 and fixed above the dual-shaft mixing chamber 2.

[0033] Through the above technical solution, the waste core material silo 3 is used to store crushed waste core materials for fire doors, such as foamed cement boards, pearl boards, etc.; the cement silo 4 is used to store ordinary cement, coagulants, etc.; and the water metering silo 5 is used to store water. Different materials are fed into the biaxial mixing chamber 2 below from the waste core material silo 3, cement silo 4, and water metering chamber 5, respectively. At the same time, the bottom of the waste core material silo 3 and cement silo 4 are equipped with weighing hoppers for precise material feeding. The water metering chamber 5 is also connected to the water inlet pipe 51 and is equipped with a flow meter to precisely control the amount of water added. The biaxial mixing chamber 2 brings the particle size, moisture content, and mixing degree of the mixture to a plastic state, and finally, the mixture falls from the discharge port below.

[0034] like Figure 3 As shown, the dual-shaft mixing chamber 2 further includes a chamber body 22, a chamber cover 21, and a mixing shaft 23. The mixing shaft 23 is provided with a plurality of inclined scrapers 24 that fit against the inner wall of the chamber body 22. The inclined scrapers 24 are connected to the mixing shaft 23 through connecting rods. The inclined scrapers 24 abut against the inner wall of the chamber body 22 and form an angle with the inner wall of the chamber body 22.

[0035] With the above technical solution, the inclined scraper 24 abuts against the bin body 22. When the stirring shaft 23 rotates, it will drive the inclined scraper 24 to scrape the inner wall of the bin body 22, scraping off the mixture remaining on the inner wall of the bin body 22, avoiding the solidification and waste of the mixture, and facilitating subsequent cleaning of the bin body 22.

[0036] like Figures 4-5As shown, a cleaning assembly 6 is further provided above the dual-shaft mixing chamber 2. The cleaning assembly 6 includes, from top to bottom, a telescopic cylinder 62, a mounting plate 61, and a spray head 63. The spray head 63 is connected to the water inlet pipe 51 via a telescopic hose. The mounting plate 61 is slidably connected to the column on the mounting frame 1. The mounting plate 61 and the spray head 63 move up and down via the telescopic cylinder 62. The cylinder body of the telescopic cylinder 62 is connected to the top frame of the mounting frame 1. The piston rod of the telescopic cylinder 62 is connected to the mounting plate 61. The mounting plate 61 is located below the discharge ports of the waste core material silo 3, cement silo 4, and water metering silo 5. The mounting plate 61 and the silo cover 21 are provided with openings corresponding to the discharge ports of the waste core material silo 3, cement silo 4, and water metering silo 5. The silo cover 21 has a middle opening and closing structure. The silo cover 21 is provided with a through hole 25 corresponding to the position of the spray head 63. A plug 26 is provided in the through hole 25.

[0037] Through the above technical solution, the mounting plate 61 moves up and down via the telescopic cylinder 62, preventing it from colliding with the exterior of the waste core material bin 3, cement bin 4, and water metering bin 5. After the dual-shaft mixing bin 2 finishes mixing, the telescopic cylinder 62 drives the mounting plate 61 downward, allowing multiple spray nozzles 63 to be inserted into the corresponding through holes 25 on the lower bin cover 21, thus spraying water to rinse the inside of the bin 22. Simultaneously, the multiple spray nozzles 63 can spray water to various locations within the bin 22, increasing the spray range and facilitating the mixing and cleaning of the mixing shaft 23. In another embodiment, the cleaning component 6 can replace the function of the water metering bin 5, adding water to the mixture within the bin 22 via the cleaning component 6.

[0038] Furthermore, a plurality of the spray heads 63 are arranged in an array below the mounting plate 61, the outer diameter of the spray head 63 being smaller than the inner diameter of the through hole 25, and the length of the spray head 63 being greater than the depth of the through hole 25.

[0039] With the above technical solution, the spray head 63 can be fully inserted into the chamber 22, and the spray head 63 will not collide with the inner wall of the through hole 25.

[0040] Furthermore, the plug 26 has a frustum structure, with its small end located inside the through hole 25 and its large end located inside the chamber body 22. A tension spring 27 is provided between the large end of the plug 26 and the lower end face of the chamber cover 21. The lower end of the spray head 63 is provided with an abutment post 64 and a nozzle 65. The abutment post 64 is located at the center of the lower end of the spray head 63, and a plurality of nozzles 65 are arranged in a circumferential array outside the abutment post 64. The nozzles 65 and the abutment post 64 are arranged at an angle, and the lower end of the abutment post 64 extends out of the nozzle 65.

[0041] Through the above technical solution, the tension spring 27 holds the plug 26 and the bin cover 21, causing the plug 26 to block the through hole 25, preventing the mixture in the bin 22 from splashing out of the through hole 25 during stirring. During cleaning, the abutment post 64 below the spray head 63 first contacts the small end of the plug 26. As the telescopic cylinder 62 moves the spray head 63 further down, the abutment post 64 pushes the plug 26 out of the through hole 25, creating a gap between the plug 26 and the bin cover 21. This gap allows the nozzles 65 on the circumference of the abutment post 64 to spray water into the bin 22.

[0042] like Figure 6 As shown, the nozzle 65 is tilted downwards. After the plug 26 is pushed out of the through hole 25, the spray head 63 is inserted into the chamber 22. Water will spray obliquely downwards from the nozzle 65 to the inside of the chamber 22, which can rinse the inner wall of the chamber 22 and the stirring shaft 23.

[0043] like Figure 7 As shown, the nozzle 65 is tilted upwards. After the plug 26 is pushed out of the through hole 25, the spray head 63 is inserted into the chamber 22. Water will spray from the nozzle 65 upwards at an angle onto the bottom surface of the chamber cover 21, which can effectively clean the chamber cover 21 and increase the cleaning range.

[0044] Meanwhile, the compartment cover 21 has a center opening structure, which allows the cleaning component 6 to be lifted and the compartment cover 21 to be opened for internal inspection.

[0045] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
