Abstract
Description
Technical Field
[0001] This utility model relates to a resin sand vibratory crusher, belonging to the field of crusher technology. Background Technology
[0002] After the resin sand is used in the resin sand process, the demolding and sintering of the resin sand also bring certain difficulties to the regeneration. If the old sand is mixed with the new sand, it is easy to cause instability of the molding sand and seriously damage the quality of the castings. The crusher is the first regeneration equipment in the resin sand regeneration equipment. The resin sand after falling is still in clumps. After being crushed by the vibration of the crusher, the molding sand is crushed into molding sand that meets the requirements. Therefore, the crushing frame in the crusher plays a crucial role. At present, most crushers have the base and the grid set in parallel, which makes it difficult for the sand particles to flow in the same direction during vibration, making it inconvenient to screen the sand. Utility Model Content
[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and to provide a resin sand vibratory crusher with a reasonable structural design.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The resin sand vibrating crusher includes a base, a machine body, a spring, and a vibrating motor. The spring is installed on the base, and the machine body is installed on the spring. A bottom plate is provided at the bottom of the machine body, and the vibrating motor is installed on the bottom plate. Its structural features are: it also includes a grid, a separation chamber, a separation port, and a screen. The grid is installed in the machine body and forms a lower cavity between the grid and the bottom plate. A separation port for connecting the lower cavity and the separation chamber is provided on the side wall of the machine body. The screen is installed in the separation chamber and divides the separation chamber into a slag discharge chamber and a sand discharge chamber. A slag discharge port is provided on the side wall of the slag discharge chamber, and a sand discharge port is provided at the bottom of the sand discharge chamber.
[0005] Furthermore, an adjustment plate is installed at the separation port.
[0006] Furthermore, spring seats are provided at the top of the base and the bottom of the body, and the springs are fitted onto the spring seats.
[0007] Furthermore, the size of the sieve is 6 mesh.
[0008] Furthermore, the grille is installed obliquely inside the machine body.
[0009] Furthermore, the bottom of the machine body is provided with a base plate at an angle.
[0010] Compared with the prior art, the present invention has the following advantages: the bottom plate and the grid of the resin sand vibrating crusher are both inclined and in opposite directions. The grid and the sand outlet are made into opposite slopes, which can extend the sand flow path. The bottom plate is inclined towards the sand outlet, which facilitates the sand to flow into the separation chamber. The amount of sand entering the separation chamber can be controlled by the set adjustment plate. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0015] Example
[0016] See Figures 1 to 2 As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.
[0017] The resin sand vibratory crusher in this embodiment includes a base 1, a body 2, a spring 3, a vibratory motor 4, a grid 5, a separation chamber 7, a separation port 8, and a screen 10. The spring 3 is installed on the base 1, and the body 2 is installed on the spring 3. A base plate 6 is inclinedly provided at the bottom of the body 2, and the vibratory motor 4 is installed on the base plate 6. Spring seats 13 are provided at the top of the base 1 and the bottom of the body 2, and the spring 3 is fitted over the spring seats 13.
[0018] In this embodiment, the grid 5 is installed obliquely inside the machine body 2, forming a lower cavity between the grid 5 and the bottom plate 6. The side wall of the machine body 2 is provided with a separation port 8 for connecting the lower cavity and the separation chamber 7. An adjusting plate 9 is installed at the separation port 8. The screen 10 is installed inside the separation chamber 7 and divides the separation chamber 7 into a slag discharge chamber and a sand discharge chamber. The side wall of the slag discharge chamber is provided with a slag discharge port 11, and the bottom of the sand discharge chamber is provided with a sand discharge port 12. The screen 10 has a size of 6 mesh.
[0019] Specifically, the resin sand vibratory crusher uses a vibratory motor 4 as the vibration source to process old sand blocks from resin sand casting molds into granules. Under the excitation force of the vibratory motor 4, which is fastened to the lower part of the machine body, the machine body 2 moves up and down. Under the vibration, the sand blocks collide and rub against the grid 5, and between sand blocks or sand particles, causing the sand blocks to break into sand particles. Then, through the sorting of the grid 5, the impurities and sand particles in the sand are effectively separated. At the same time, the resin film that has been cured on the sand particles can be removed to a certain extent, which has a certain soft regeneration effect, and sand that meets the particle size distribution requirements is obtained.
[0020] After the sand block is broken into sand particles, it falls through the gap of the grid 5 into the lower cavity, while the debris that cannot be broken remains on the grid 5. The bottom plate 6 of the machine body 2 is a steel plate that slopes towards the separation port 8. The sand particles can flow from the gap under the adjustment plate 9 of the separation port 8 onto the screen 10. The screen 10 can screen out sand particles larger than 8 mesh or small sand clumps that have not been broken, and discharge them through the slag outlet 11. The recovered qualified sand flows out from the sand outlet 12 below the screen 10.
[0021] The grid 5 and the sand outlet 12 are made with opposite slopes. As long as the slag outlet 11 at the rear of the machine body 2 is opened at regular intervals and the machine is started, the garbage can be automatically vibrated out.
[0022] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in these claims, all of which should fall within the protection scope of this utility model.
