Description

Technical Field

[0001] This utility model relates to the field of porous hollow brick technology, specifically a raw material screening machine for processing porous hollow bricks. Background Technology

[0002] Porous hollow bricks are block materials made primarily from clay, shale, coal gangue, fly ash, etc., through molding and firing. They have a porosity of not less than 25%, and the pores are mostly vertically connected. Their core characteristics are "uniform pore distribution and regular pore shape". They are mainly used for building wall construction, and have both load-bearing and non-load-bearing functions. They are an energy-saving wall material that can replace traditional solid clay bricks.

[0003] The existing announcement number CN214132670U discloses a coal gangue raw material screening machine for producing hollow bricks, including an annular tube fixing frame. Annular tube grooves are provided at both ends of the annular tube fixing frame. Annular tube sliding wheels are placed inside the annular tube grooves. The annular tube sliding wheels are installed at one end of an annular tube sliding rod, and the other end of the annular tube sliding rod is connected to an annular tube fixing frame. An annular tube screen is fixed inside the annular tube fixing frame by fixing rings. This utility model utilizes the cooperation of the annular tube fixing frame, annular tube grooves, annular tube sliding rod, annular tube sliding wheel, annular tube fixing frame, annular tube screen, annular tube drive motor, annular tube turntable, annular tube rotating shaft, annular tube driven shaft, annular tube transmission rod, a second fixing frame, a second groove, a second sliding rod, a second sliding wheel, a second fixing frame, a second screen, a second drive motor, a second turntable, a second rotating shaft, a second driven shaft, and a second transmission rod to perform multi-stage screening of coal gangue raw materials, thereby improving screening efficiency.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] Although the aforementioned patent can screen hollow bricks, when the raw material enters the screening machine from the feed pipe, the vibration of the screening machine body causes shearing motion in the raw material layer, resulting in intense friction between particles and generating new dust. During the vibration process, local airflow disturbances are formed, which carry loose dust particles away from the raw material layer, forming flying dust. This dust not only pollutes the production environment and damages the screening machine parts and contaminates the raw materials, but also causes respiratory diseases due to long-term inhalation of dust particles by operators. Therefore, a raw material screening machine for processing porous hollow bricks is proposed to solve the problems mentioned above. Utility Model Content

[0024] 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.

[0025] Example:

[0026] Please see Figure 1 - Figure 4 In this embodiment, a raw material screening machine for processing porous hollow bricks includes a frame 1, a screening machine body 2 is arranged inside the frame 1, a feed pipe 3 is connected to the top of the screening machine body 2, a cleaning component 4 is arranged on the top of the screening machine body 2, and a collection component 5 is arranged on the top of the screening machine body 2.

[0027] The cleaning component 4 includes a rectangular ring 41, which is fixedly installed on the top of the surface of the feed pipe 3, and the interior of the rectangular ring 41 is connected to an air inlet head 42.

[0028] The collection component 5 includes a collection box 51, which is fixedly installed at the bottom and top of the screening machine body 2. A collection chamber 52 is slidably installed inside the collection box 51.

[0029] When in use, the raw materials such as clay and shale required for processing porous bricks are fed into the screening machine body 2 through the feed pipe 3. At this time, the collection bin 52 has been pre-slid into the collection box 51 to prepare for subsequent dust collection. Meanwhile, the rectangular ring 41 and the air inlet head 42 are in a standby state. Airflow can be introduced through the air inlet head 42 to initially reduce the dust diffusion generated when the raw materials are fed in, and ensure a clean screening environment.

[0030] The cleaning component 4 also includes an annular tube 43, which is fixedly installed at the bottom of the surface of the feed tube 3. The top of the annular tube 43 is connected to a connecting tube 44, and the top of the connecting tube 44 extends into the interior of the rectangular ring 41 and is connected to the rectangular ring 41.

[0031] The front end of the annular pipe 43 is connected to a fixed pipe 45. The front end of the fixed pipe 45 passes through the inside of the collection box 51 and is connected to the collection box 51. A blower 46 is fixedly installed on the top of the collection box 51. The output end of the blower 46 passes through the inside of the collection box 51 and is connected to the collection box 51. The output end of the blower 46 is connected to a small cyclone water separator.

[0032] A water tank 47 is fixedly installed on the back of the collection box 51. A water pump 48 is fixedly installed on the bottom of the inner wall of the water tank 47. One end of the water pump 48 is connected to a water pipe 49. The bottom of the water pipe 49 extends into the inside of the collection box 51. A spray head 410 is fixedly installed inside the collection box 51. The bottom of the water pipe 49 and the top of the spray head 410 are connected.

[0033] The top of the water tank 47 is connected to the water inlet 6, and a filter screen 7 is fixedly installed inside the water inlet 6.

[0034] In use, the exhaust fan 46 and water pump 48 are started. The exhaust fan 46 creates negative pressure in the collection box 51. Outside air enters the rectangular ring 41 through the air inlet 42 and is then transported to the inside of the annular pipe 43 through the connecting pipe 44. The airflow adsorbs dust from the raw materials falling into the pipe from all directions. The dust-laden airflow enters the collection box 51 through the fixed pipe 45. At the same time, the water pump 48 transports water from the water tank 47 to the spray head 410 through the water pipe 49. The spray head 410 sprays water mist into the collection box 51 to reduce the dust in the airflow and prevent the dust from being re-entrained. Finally, the dust particles after dust reduction fall into the collection chamber 52 for collection. At this time, the small cyclone water separator prevents water mist from entering the inside of the exhaust fan 46.

[0035] Please see Figure 1 - Figure 4 The collection assembly 5 also includes a partition 53, and a screening screen 54 is fixedly installed inside the collection chamber 52, with the top of the screening screen 54 in contact with the bottom of the partition 53.

[0036] The front side of the collection chamber 52 extends to the front side of the collection box 51. A connecting plate 55 is fixedly installed at the front end of the collection chamber 52. Magnets 56 are fixedly installed on the back of the connecting plate 55 and the front side of the collection box 51. The two sets of magnets 56 attract each other.

[0037] When in use, after the raw material screening is completed and the dust collection is finished, the connecting plate 55 can be pulled outward. The connecting plate 55 will cause the collection bin 52 to slide out of the collection box 51. The screening screen 54 in the collection bin 52 cooperates with the partition plate 53 to initially separate the collected dust and a small amount of impurities. The screening screen 54 filters out large particles of impurities, which is convenient for subsequent centralized cleaning. After cleaning, the collection bin 52 is pushed back into the collection box 51 until the connecting plate 55 and the magnet 56 on the collection box 51 are attracted and fixed again to ensure that the collection bin 52 is installed firmly.

[0038] The working principle of the above embodiments is as follows:

[0039] During use, an appropriate amount of clean water is injected into the water tank 47 through the inlet 6. The filter screen 7 prevents impurities from entering the water tank 47. First, the exhaust fan 46 is started to create a stable negative pressure in the collection box 51. Then, the water pump 48 is started, which transports the clean water in the water tank 47 to the spray head 410 through the water pipe 49, causing the spray head 410 to spray a uniform water mist into the collection box 51. At this time, the small cyclone water separator prevents water mist from entering the exhaust fan 46. Then, the clay and shale required for porous hollow brick processing are added. As the raw material is slowly fed into the screening machine body 2 along the feed pipe 3, the negative pressure generated by the exhaust fan 46 during the falling process guides the outside air into the rectangular ring 41 through the air inlet 42, and then diverts it to the annular pipe 43 through the connecting pipe 44. The airflow completely surrounds the raw material falling in the feed pipe 3, thereby adsorbing the dust carried in the raw material. The dust-laden airflow is sucked into the collection box 51 through the fixed pipe 45 and then comes into contact with the water mist sprayed by the spray head 410. The dust particles are adsorbed and settled by the water mist, and the wetted raw material smoothly enters the screening machine body 2 to complete the screening operation.

[0040] Once the dust inside the collection chamber 52 is full, the connecting plate 55 can be pulled outwards. The connecting plate 55 overcomes the attraction of the two sets of magnets 56, thus allowing the collection chamber 52 to slide smoothly out of the collection box 51. The top of the screening screen 54 contains larger particles of impurities, while the inside of the collection chamber 52 contains settled dust. The screening screen 54 is then removed to clean the large particles of impurities, and the dust inside the collection chamber 52 is poured out. The cleaned screening screen 54 is then placed back into the collection chamber 52, and the collection chamber 52 is pushed back into the collection box 51 until the connecting plate 55 and the collection box 51 are in contact, and the two sets of magnets 56 attract and fix each other, ensuring that the collection chamber 52 is installed securely.

[0041] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
