[0030] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0032] It will be appreciated that spatial relationship terms such as "under", "beneath", "below", "under", "above", "above", etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It should be understood that in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, the element or feature described as "under other elements" or "under it" or "under it" will be oriented as "on" the other elements or features. Therefore, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0033] See also Figure 1-5A filtering device for chemical raw material production includes a feed bin 1, a filter element 2, a connecting platform 3, a peripheral element 4, a positioning element 5 and a fixing element 6. The filter element 2 is equidistantly distributed in the feed bin 1 from top to bottom, the connecting platform 3 is arranged between the filter element 2 and the feed bin 1, the peripheral element 4 is arranged between the connecting platform 3 and the feed bin 1, the positioning element 5 is arranged on the peripheral element 4 and contacts the feed bin 1, and the fixing element 6 is arranged on the feed bin 1.

[0034] According to the prior art, ammonium thiosulfate can be used as an intermediate conversion chemical raw material to produce chemical products such as thiosulfate, potassium thiosulfate and calcium thiosulfate through chemical reactions. The filtering equipment used in the production process is usually a sealed container with a structure that can filter multiple times inside. The present embodiment is based on multiple filtrations. The filter element 2 is pushed into the feed bin 1 from top to bottom in sequence through the connecting platform 3, forming an inward force to set up the filter element 2 in the feed bin 1, and then the peripheral component 4 is embedded in the feed bin 1 to construct an inner filtering space with a sealed edge of the feed bin 1. At the same time, it can be combined with the connecting platform 3 to form a filtered impurity collection part. During the process of pressing the peripheral component 4 into the feed bin 1, the positioning component 5 is accurately pushed into the feed bin 1 with the assistance of the fixing component 6. Finally, the fixing component 6 is operated to be equal to the positioning component 5, which indirectly restricts the connecting platform 3 and the filter element 2 to form a filtering component located below the feed opening of the feed bin 1.

[0035] Based on the above, if there are too many separated raw materials accumulated on the filter element 2 in the feed bin 1, they can be separated from the positioning element 5 by operating the fixing element 6, and then the peripheral element 4 is pulled outward from the positioning element 5 along the fixing element 6 to pull the connecting platform 3 and the filter element 2 outward, and then the peripheral element 4 is flipped outward to limit the contact between the connecting platform 3 and the filter element 2 on the same horizontal plane, and finally the separated raw materials on the connecting platform 3 and the filter element 2 are cleaned, so that the separated raw materials on the filter structure outside the equipment can be cleaned, the operation is simple, and normal filtering of the raw materials is ensured.

[0036] See also Figure 1-5 The filter element 2 is composed of a filter frame 21 divided into two halves and hingedly connected. A baffle 22 is provided on the filter frame 21, and one end of the baffle 22 extends to the top of the filter frame 21 on the other side. The connecting platform 3 is hinged to the filter frame 21, and waste discharge ports arranged symmetrically and equidistantly are opened on the feed bin 1, and one end of the connecting platform 3 extends into the waste discharge port.

[0037] In the above-mentioned process of assembling the filter element 2 by pushing the connecting platform 3 into the feed bin 1, the filter frame 21 and the connecting platform 3 are hinged three times to form a four-section rotatably connected component, and the connecting platforms 3 are respectively located on both sides of the filter frame 21. When the connecting platform 3 is pushed into the feed bin 1 through the waste outlet, the filter frame 21 is squeezed on both sides and hinged in the middle to rotate and arch upward. After the connecting platform 3 completely enters the waste outlet, the filter frame 21 is arranged in the feed bin 1 in an inclined state.

[0038] Taking into account that the raw materials may leak and fall from the hinge of the filter frame 21, this embodiment installs a baffle 22 on one side of the filter frame 21. The baffle 22 blocks the top of the hinge to guide the falling raw materials to move toward the filter frames 21 on both sides and slide to the connecting platform 3.

[0039] The hinged joint between the connecting platform 3 and the filter frame 21 is located in the feed bin 1 to prevent leakage of separated raw materials. In this embodiment, the feed bin 1 is symmetrically provided with discharge ports arranged at equal distances. The discharge ports and waste discharge ports are alternately distributed. A guide plate 7 is provided on the discharge port. The guide plate 7 is located below the connection between the connecting platform 3 and the filter frame 21. A closing plate 8 is embedded on the discharge port.

[0040] The discharge port is blocked by the closing plate 8, and a temporary storage position is formed under the connecting platform 3 in cooperation with the guide plate 7. The leaked raw materials are accumulated between the guide plate 7 and the closing plate 8 along the inclined guide plate 7. The accumulated raw materials can be collected and processed later by removing the closing plate 8.

[0041] See also Figure 1-5 The peripheral member 4 includes a panel 41 and a lifting ear 42. The panel 41 is arranged on the connecting platform 3 through the lifting ear 42. The panel 41 is located above the connecting platform 3 and is embedded in the waste outlet.

[0042] It should be noted that the enclosure 41 is a plate with a concave cross-section. Before the connecting platform 3 is pushed into the waste discharge port, the enclosure 41 can be pushed by the lifting ear 42 to rotate to the top of the connecting platform 3. Then, after the connecting platform 3 is pushed into the waste discharge port, the enclosure 41 cooperates with the connecting platform 3 to be embedded in the waste discharge port, so that the feed bin 1 is completely closed. At the same time, the enclosure 41 is restricted in the waste discharge port, forming a storage space above the connecting platform 3, which can store raw materials that slide off the filter frame 21.

[0043] See also Figure 1-5 A handle 43 is provided on the enclosure 41, a positioning member 5 is provided on the handle 43, the fixing member 6 includes a guide seat 61 provided on the feed bin 1, a socket is provided on the guide seat 61, a limiting rod 62 is provided above the guide seat 61 through the socket, the guide seat 61 is located above the positioning member 5, and one end of the limiting rod 62 passes through the socket and contacts with the positioning member 5.

[0044] The above-mentioned enclosure 41 is rotated to the connecting platform 3 and pushed into the waste discharge port together. In this embodiment, a handle 43 is set on the enclosure 41, and the enclosure 41 is operated by the handle 43 to move to the connecting platform 3 first. The follow-up positioning member 5 is set in a vertical state. When the enclosure 41 and the connecting platform 3 are pushed to move, the positioning member 5 contacts the guide seat 61 and moves along the guide seat 61, which can assist the connecting platform 3 to be accurately pushed into the waste discharge port. When the positioning member 5 contacts the feed bin 1, the positioning member 5 is pressed on the feed bin 1 by inserting the limit rod 62 into the socket to complete the fixation of the enclosure 41, the connecting platform 3 and the filter frame 21.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
