Description

Technical Field

[0001] This utility model relates to a sand-lifting and filtering device and a sand-lifting and filtering device. Background Technology

[0002] In existing technology, a sand-floating machine is a sand bucket. During use, the wax mold that has been impregnated with slurry is placed into the sand bucket, and then, under the action of a blower, the sand and gravel float up and adhere to the surface of the wax mold. During this process, excess slurry drips into the sand bucket, causing the sand and gravel to agglomerate into large particles. These agglomerated sand and gravel particles can affect product quality.

[0003] Patent application number 2024211345870 discloses a sand-floating machine with a circulating filter, including a base, a sand-floating bucket on the base, a sand discharge port on the sand-floating bucket, a valve on the sand discharge port, and a sand-gravel filter assembly below the sand discharge port for filtering sand and gravel. Compared with the prior art, when it is necessary to screen and filter the sand and gravel in the sand-floating bucket, the valve of the sand discharge port is opened, so that the sand and gravel in the sand-floating bucket are output to the sand-gravel filter assembly. Under the action of the sand-gravel filter assembly, the clumped sand and gravel can be screened and the unclumped sand and gravel can be reused. This not only saves labor but also ensures product quality and is beneficial to production operations.

[0004] However, the process of using a hoist to lift gravel has the following two drawbacks: 1. The hoist will cause some gravel to be worn during the lifting process; 2. The hoist needs to run for a long time, and its lifting efficiency is too low. Utility Model Content

[0005] Based on the two shortcomings of the existing technology, this utility model provides a floating sand lifting and filtering device and a floating sand machine with a floating sand lifting and filtering device.

[0020] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

[0021] This embodiment mainly describes the title of the floating sand lifting and filtering device, as follows: Reference Appendix Figure 1-3 The floating sand lifting and filtering device 10 includes: Rack 101; The lifting chamber 102 is mounted on the frame 101 in a liftable manner. It has a sand storage chamber and a discharge port on its side wall. Its bottom wall is inclined and the lowest point of the inclined surface is located at the discharge port. A control switch is located at the discharge port to control the discharge. The filter device 30 is located on the upper side of the frame 101, and the discharge port of the lifting chamber 102 connects with the filter device 30 after it is raised. This design uses the lifting chamber 102 to lift and filter floating sand after a certain amount of sand has accumulated, allowing for reuse. During this process, the sand will not generate excessive friction with the lifting device, ensuring that the particle size of the sand meets the requirements for reuse. Furthermore, the lifting chamber 102 collects the sand, and after a certain amount is collected, it is lifted again for filtration. The drive structure of the lifting chamber 102 starts intermittently, resulting in higher efficiency compared to a traditional lifting machine. The filter device 30 is a screen-type filter.

[0022] Preferably, the lifting chamber 102 is slidably mounted on the frame 101. The sliding structure has relatively strong stability, while direct hoisting would cause swaying.

[0023] Preferably, the frame 101 is equipped with a lifting drive device, which is one of the following: a telescopic structure, a hoisting structure 103, and a screw mechanism. The telescopic structure includes various types of telescopic cylinders, and the hoisting structure 103 includes hoisting hoists, pulley hoisting structures, etc.

[0024] Preferably, the frame 101 is provided with a perforated slide rail 1011, and the lifting chamber 102 is provided with a slider 1021 extending into the perforated slide rail 1011. The slider 1021 can be a fixed structure or a rotating structure. The lifting chamber 102 is also provided with a roller 1022 that abuts against the inner sidewall opposite to the frame 101. Both the slider 1021 and the roller 1022 are used for limiting movement, and the roller 1022 can reduce friction and wear.

[0025] Preferably, the filter device 30 has a feed inlet, and the discharge outlet connects with the feed inlet after the lifting chamber 102 is raised to a set height. In this design, the connection structure ensures that the sand and gravel fall stably into the filter device 30 for filtration. Example

The blower 202 is connected to the storage bin 201 for blowing air into the storage bin 201. It also includes the aforementioned flotation sand lifting and filtering device 10. The storage bin 201 has a discharge channel 2011 on its wall. The discharge channel 2011 extends above the lifting bin 102 so that the sand processed by the flotation machine 20 falls into the lifting bin 102. The discharge port of the filtering device 30 is connected to the storage bin 201 to add the filtered sand and gravel into the storage bin 201.

[0027] Preferably, the outlet of the material discharge channel 2011 is located outside the lifting trajectory of the lifting chamber 102 to avoid interference. During material discharge, the gravel falls into the lifting chamber 102 in a parabolic trajectory.

[0028] Preferably, the opening of the material feeding channel 2011 is equipped with an electrically controlled valve or a manual valve. This solution controls the material feeding by setting up a valve.

[0029] Preferably, the electrically controlled valve or the manually operated valve is a slide gate type, a sealing plate type, or a built-in valve.

[0030] As a preferred embodiment, the sand-floating machine 20 also includes a recovery box 203, which is arranged side by side with the storage bin 201. Some of the sand and gravel in the storage bin 201 are blown up and fall into the recovery box 203.

[0031] It should be noted that the lifting process of the lifting chamber 102 can be controlled by sensors, such as a gravity sensor to sense the weight of the gravel, and automatically start lifting when the weight is reached. The lifting position is sensed by a position sensor set on the frame 101.

[0032] The above provides a detailed description of the floating sand lifting and filtering device and the floating sand machine with the floating sand lifting and filtering device provided by this utility model. Specific examples are used in this article to illustrate the principle and implementation of this utility model. The above description of the embodiments is only for the purpose of helping to understand this utility model and its core ideas.
