Description

Technical Field

[0001] This utility model relates to the field of waste incineration slag treatment technology, specifically to a waste incineration slag separation device. Background Technology

[0002] Waste incineration is a common waste disposal method that effectively reduces the volume and weight of waste while recovering energy. However, the incineration process produces a large amount of slag containing particles of different sizes, which needs to be effectively separated for subsequent resource recovery or landfill disposal.

[0003] Currently, existing slag separation devices typically use screening or air classification to perform preliminary separation of slag. However, in order to improve the separation effect, they employ complex mechanical structures, which not only increase equipment costs but also increase maintenance difficulty. Furthermore, the slag has a short residence time and flow path on the filter screen in the separation device, resulting in unsatisfactory separation effect. Utility Model Content

[0004] The purpose of this invention is to provide a waste incineration slag separation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste incineration ash separation device, comprising:

[0006] A separation box is provided, which has a discharge chamber and a separation groove above the discharge chamber. A conical filter screen is fixed at the bottom opening of the separation groove, and a spiral baffle is fixed on the upper side of the conical filter screen. The side wall of the separation box is provided with a first discharge port and a second discharge port.

[0007] A support plate is located below the separation box. A support column connects the support plate to the separation box. A vibration motor is installed in the upper center of the support plate, and a shock absorption component is provided at the bottom of the support plate.

[0008] Preferably, the first discharge port is located on the left side of the separation box and is connected to the separation tank. The outer end of the spiral baffle is connected to the inner wall of the separation tank, so that the slag separated in the separation tank can be directly discharged from the first discharge port, avoiding the accumulation of materials in the separation tank and improving the discharge efficiency.

[0009] Preferably, the second discharge port is located on the right side of the separation box and is connected to the discharge chamber. The bottom right end of the discharge chamber is level with the bottom edge of the second discharge port, so that the slag falling into the discharge chamber can be directly discharged from the second discharge port.

[0010] Preferably, the bottom wall of the discharge chamber is designed with an inclined structure that is higher on the left and lower on the right, so that the slag automatically flows to the second discharge port on the right, further improving the discharge efficiency.

[0011] Preferably, there are multiple support columns arranged in a circular array on the support plate. The bottom end of each support column is connected to the support plate by bolts, and the top end of each support column is connected to the bottom of the separation box. This arrangement can evenly distribute the weight of the separation box and improve the stability of the device.

[0012] Preferably, the shock absorption assembly includes an annular base, on which multiple shock absorbers are fixed. The upper end of each shock absorber is connected to the bottom of the support plate, which can improve the stability of the device when placed on the ground.

[0013] Preferably, the conical filter screen is made of stainless steel. Stainless steel conical filter screens have high mechanical strength and can withstand greater impact from slag, thus reducing the frequency of replacement of the conical filter screen.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This separation device has a simple structure. Through the combination design of conical filter screen and spiral baffle, the residence time and flow path of slag on the conical filter screen are increased, which can effectively perform preliminary separation of slag and improve the separation effect.

[0016] 2. The vibration motor installed on the support plate can cause the separation box to vibrate. This vibration can accelerate the movement of slag on the conical filter screen, allowing the slag particles to come into more full contact with the conical filter screen, thereby speeding up the separation speed and further improving the separation efficiency.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1 to 4 The waste incinerator ash separation device shown includes:

[0026] The separation box 1 has a discharge chamber 2 inside, a separation groove 3 above the discharge chamber 2, a conical filter screen 4 fixed at the bottom opening of the separation groove 3, a spiral baffle 5 fixed on the upper side of the conical filter screen 4, and a first discharge port 9 and a second discharge port 10 on the side wall of the separation box 1.

[0027] Support plate 6 is located below separation box 1. Support column 7 connects support plate 6 and separation box 1. Vibration motor 8 is installed in the middle of the upper side of support plate 6. Shock absorption component is provided at the bottom of support plate 6.

[0028] The first discharge port 9 is located on the left side of the separation box 1. The first discharge port 9 is connected to the separation tank 3. The outer end of the spiral baffle 5 is connected to the inner wall of the separation tank 3, so that the slag separated in the separation tank 3 can be directly discharged from the first discharge port 9, avoiding the accumulation of materials in the separation tank 3 and improving the discharge efficiency.

[0029] The second discharge port 10 is located on the right side of the separation box 1. The second discharge port 10 is connected to the discharge chamber 2. The bottom right end of the discharge chamber 2 is level with the bottom edge of the second discharge port 10, so that the slag falling into the discharge chamber 2 can be directly discharged from the second discharge port 10.

[0030] The bottom wall of the discharge chamber 2 is designed with an inclined structure that is higher on the left and lower on the right, so that the slag automatically flows to the second discharge port 10 on the right, further improving the discharge efficiency.

[0031] Multiple support columns 7 are provided, and the multiple support columns 7 are distributed in a ring array on the support plate 6. The bottom end of the support column 7 is connected to the support plate 6 by bolts, and the top end of the support column 7 is connected to the bottom of the separation box 1. This can evenly distribute the weight of the separation box and improve the stability of the device.

[0032] The shock absorption assembly includes an annular base 11, on which multiple shock absorbers 12 are fixed. The upper end of the shock absorber 12 is connected to the bottom of the support plate 6, which can improve the stability of the device when placed on the ground.

[0033] The cone-shaped filter screen 4 is made of stainless steel. The stainless steel cone-shaped filter screen 4 has high mechanical strength and can withstand greater impact from slag, thus reducing the frequency of replacement of the cone-shaped filter screen 4.

[0034] In this invention, the vibration motor 8 installed on the support plate 6 can cause the separation box 1 to vibrate. The vibration of the separation box 1 drives the conical filter screen 4 to vibrate, and the slag is poured onto the top of the conical filter screen 4, that is, the center of the spiral baffle 5. The vibration of the conical filter screen 4 causes the slag to move along the path formed by the spiral baffle 5, which increases the residence time and flow path of the slag on the conical filter screen, and can effectively perform preliminary separation of the slag, thus improving the separation effect. At the same time, the vibration makes the slag particles more fully contact the conical filter screen, thereby accelerating the separation speed, further improving the separation efficiency, and preventing the conical filter screen from clogging. The slag separated in the separation tank 3 can be directly discharged from the first discharge port 9, and the slag falling into the discharge chamber 2 can be directly discharged from the second discharge port 10.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
