Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology for sand removal machines, and in particular to a vibrating screen for sand removal machines used for cleaning sand from castings. Background Technology

[0002] The sand removal machine is a key piece of equipment in the casting production process. It is mainly used to separate molding sand from castings and to perform preliminary screening of the sand. It generates high-frequency vibration through a vibrating motor or other vibration source, which drives the vibrating screen to vibrate violently. During the vibration process, the molding sand attached to the castings is separated from the castings due to the vibration force.

[0003] The process of treating waste sand in castings includes separation, collection, magnetic separation, crushing, and humidification. Separation is completed on a vibrating screen. The crushing process aims to break larger or agglomerated sand particles into smaller particles that meet the requirements of the casting process. In actual production, some of the sand falling from the vibrating screen of the sand removal machine already meets the requirements after crushing. If this sand continues to enter the subsequent crushing process, it will cause many problems. On the one hand, the crushing equipment will consume additional electricity when processing this part of qualified sand, resulting in energy waste. On the other hand, this part of sand will occupy a lot of processing time and reduce the overall working efficiency of the crushing equipment. In order to solve the above problems, we have proposed this vibrating screen for sand removal in castings. Utility Model Content

A filtering mechanism for filtering sand is provided inside the screen frame. The filtering mechanism includes a screen frame fixedly connected to the inner wall of the screen frame. The screen frame is inclined. Discharge ports are provided on both the screen frame and the side walls of the screen frame. A guiding mechanism for moving sand is provided inside the screen frame.

[0007] Preferably, the feeding mechanism includes two first guide plates fixedly connected to the bottom of the screen frame, and a third guide plate fixedly connected to the inner wall of the screen frame.

[0008] Preferably, a plurality of material distribution blocks are fixedly connected to the bottom of the screen frame, and the plurality of material distribution blocks are arranged at equal intervals.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-3 As shown, a vibrating screen for sand removal from castings includes a screen frame 1, two side plates 5 and two spring connecting seats 6. Motor mounting seats 9 and reinforcing members 4 are fixedly connected to both side walls of the screen frame 1. A perforated plate 2 is fixedly connected to the inner wall of the screen frame 1. A fence frame 3 is fixedly connected to the upper end of the perforated plate 2. A filtering mechanism for filtering sand is provided inside the screen frame 1. The filtering mechanism includes a screen frame 7 fixedly connected to the inner wall of the screen frame 1. The screen frame 7 is inclined. A discharge port 16 is opened on both the side walls of the screen frame 1 and the screen frame 7.

[0022] The screen frame 7 is equipped with a material guiding mechanism for guiding the movement of sand. The material guiding mechanism includes two first guide plates 8 fixedly connected to the bottom of the screen frame 7, and a third guide plate 17 fixedly connected to the inner wall of the screen frame 1.

[0023] In this invention, multiple material distribution blocks 14 are fixedly connected to the bottom of the screen frame 7. The multiple material distribution blocks 14 are equally spaced, which can extend the residence time of the sand in the screen frame 7 and improve the screening effect of the sand.

[0024] In this utility model, two second guide plates 13 are fixedly connected to the bottom of the screen frame 1. The side wall of the second guide plate 13 is provided with a through groove, which allows the sand material that originally fell out of the screen frame 1 to be concentrated in the middle and fall down, making it convenient to collect the sand material.

[0025] In this utility model, two suction hoods 10 are provided inside the sieve frame 1. Suction pipes 11 are connected to the suction hoods 10. Multiple connecting rods 12 are fixedly connected to the side wall of the suction hoods 10. The connecting rods 12 are fixedly connected to the adjacent side plates 5. The suction pipes 11 can be connected to external dust collection equipment through flexible hoses, which can collect the dust generated by sieving inside the sieve frame 7 and prevent the dust from escaping.

[0026] In this invention, the inner walls of the two side plates 5 are provided with multiple reinforcing rods 15. The multiple reinforcing rods 15 at the same height are equally spaced and can connect the two side plates 5, making the structure of the vibrating screen stronger.

[0027] It should be noted that this utility model is a vibrating screen for a sand removal machine used for cleaning sand from castings. The user installs the screen frame 1 on the base of the sand removal machine with bolts and nuts. Two vibrating motors are installed on two motor mounting seats 9. During the operation of the vibrating motors, the screen frame 1 vibrates. After the castings and sand are poured onto the fence frame 3, the sand on the castings falls off under continuous vibration. The sand falls onto the through-hole plate 2 and is crushed during the continuous sand process. The sand falls through the through holes of the through-hole plate 2.

[0028] The falling sand falls into the screen frame 7, and the vibrating screen frame 7 returns to the fallen sand for screening. Fine sand particles fall through the mesh of the screen frame 7 to the bottom of the screen frame body 1, while large pieces of sand are discharged from the discharge port 16. The process can screen the sand, so that the sand that meets the requirements can be separated from the many sand particles, so that it does not need to be crushed in the subsequent sand processing.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
