[0026] Example

[0027] Reference Figure 1-4 This is an embodiment of the present invention, which provides a sand production, processing and drying equipment, including:

[0028] The feeding assembly 100 includes a bracket 101, a distribution box 102 fixedly connected to the end of the bracket 101, and a hopper 103 fixedly installed on the side wall of the distribution box 102, with the bottom of the hopper 103 connected to the feed inlet on the side wall of the distribution box 102.

[0029] The drying assembly 200 includes a drying chamber 201 fixedly connected to the side wall of the support 101, a fan 202 installed on the lower side wall of the drying chamber 201, a transfer plate 203 fixedly connected to the end of the drying chamber 201, a sieve plate 204 fixedly connected to the inner side of the transfer plate 203, and a discharge pipe 205 fixedly connected to the bottom of the drying chamber 201. The end of the transfer plate 203 is fixedly connected to the bottom of the distribution box 102, and the distribution box 102 is connected to the interior of the drying chamber 201 through the transfer plate 203.

[0030] The support frame 101 serves as the structural support for the entire equipment, providing a stable installation foundation for the distribution box 102 and the hopper 103, ensuring the equipment remains stable during operation. The hopper 103 stores and initially conveys the sand to be processed. The distribution box 102 is fixedly connected to the end of the support frame 101 and docks with the bottom of the hopper 103 to receive the material conveyed by the hopper 103. It is also connected to the adapter plate 203 of the drying assembly 200 at its bottom, enabling the material to be conveyed to the drying chamber 201. The drying chamber 201 is fixedly connected to the side wall of the support frame 101 and is the core component for sand drying. The fan 202 is installed on the lower side wall of the drying chamber 201 to supply air into the sleeve 206, providing airflow power for the drying process and improving sand drying efficiency. One end of the adapter plate 203 is fixedly connected to the end of the drying chamber 201, and the other end is fixedly connected to the bottom of the distribution box 102, allowing the distribution box 102 to communicate with the interior of the drying chamber 201 and facilitating the smooth transfer of materials. The sieve plate 204 is fixedly connected to the inside of the adapter plate 203 to perform preliminary screening of the material entering the drying chamber 201, preventing larger particles or impurities from entering the drying chamber 201 and affecting the drying effect.

[0031] Specifically, the drying assembly 200 also includes a sleeve 206 fixedly connected to the inner wall of the drying chamber 201, and an electric heating wire 207 fixedly connected to the inner wall of the sleeve 206. One end of the sleeve 206 is connected to the air outlet of the fan 202, and the other end of the sleeve 206 is installed above the discharge pipe 205.

[0032] The sleeve 206 is fixedly connected to the inner wall of the drying chamber 201, with one end connected to the air outlet of the fan 202 and the other end located above the discharge pipe 205. An electric heating wire 207 is fixedly connected to its inner wall. The air delivered by the fan 202 is heated by the electric heating wire 207, forming a hot airflow that dries the sand inside the drying chamber 201.

[0033] Furthermore, the drying assembly 200 also includes a dispensing motor 208 rotatably mounted on the side wall of the dispensing box 102, and a lever 209 fixedly connected to the end of the dispensing motor 208, the lever 209 running on the side wall of the screen plate 204.

[0034] The material distribution motor 208 is rotatably installed on the side wall of the material distribution box 102, and its end is fixedly connected to the lever 209. The rotation of the motor drives the lever 209 to rotate, thereby moving the material on the screen plate 204 to promote the dispersion and conveying of the material.

[0035] Furthermore, the drying assembly 200 also includes a cover plate 210 fixedly connected to the top of the distribution box 102, and a filter element 211 inserted into the inner wall of the cover plate 210. The lower end of the filter element 211 is inserted into the inner wall of the top of the distribution box 102, and the filter element 211 is located below the exhaust hole of the cover plate 210.

[0036] The cover plate 210 is fixedly connected to the top of the distribution box 102, and a filter element 211 is inserted into its inner wall. The lower end of the filter element 211 is inserted into the inner wall of the top of the distribution box 102 and is located below the exhaust port of the cover plate 210. During the drying process, the generated hot air and dust enter the cover plate 210 through the distribution box 102. The filter element 211 filters the gas, purifies the discharged gas, and reduces environmental pollution.

[0037] Preferably, the feeding assembly 100 also includes an auger 104 rotatably mounted on the inner side of the bottom of the hopper 103, with the end of the auger 104 docking with the feed inlet on the side wall of the distribution box 102.

[0038] The end of the auger 104 is connected to the feed inlet on the side wall of the distribution box 102. By rotating the auger 104, the sand in the hopper 103 is quantitatively and stably transported to the distribution box 102.

[0039] It should be noted that the feeding assembly 100 also includes a maintenance pipe 105 that is sealed and installed on the side wall of the distribution box 102, with the upper end of the maintenance pipe 105 communicating with the side wall of the distribution box 102.

[0040] The inspection pipe 105 is sealed and installed on the side wall of the material distribution box 102, with its upper end connected to the side wall of the material distribution box 102, which facilitates the staff to inspect and maintain the inside of the material distribution box 102.

[0041] Preferably, the feeding assembly 100 further includes a pull rod 106 rotatably mounted on the side wall of the inspection tube 105, a sealing plate 107 fixedly connected in the middle of the pull rod 106, and a spring 108 fixedly connected to the side wall of the sealing plate 107, with the end of the spring 108 fixedly connected to the inner wall of the inspection tube 105.

[0042] During normal operation, the spring 108 keeps the sealing plate 107 tightly against the inner wall of the inspection tube 105, thus providing a seal. When maintenance is required, the pull rod 106 is pulled to overcome the elastic force of the spring 108 and open the sealing plate 107, allowing for maintenance operations.

[0043] In operation, the sand to be processed is placed into hopper 103, and auger 104 is started. The auger 104 rotates, conveying the sand to distribution box 102. Inside distribution box 102, the sand undergoes preliminary distribution and sorting. The sand in distribution box 102 enters drying chamber 201 through transfer plate 203, where sieve plate 204 screens the sand. Simultaneously, fan 202 starts, sending air into sleeve 206. Heating wire 207 heats the air, and the hot airflow flows within drying chamber 201, drying the sand. Distribution motor 208 drives lever 209 to rotate, preventing sand from accumulating on sieve plate 204 and ensuring the continuity of the drying process. The dried sand is discharged through discharge pipe 205. Hot air and dust generated during the drying process rise through distribution box 102 to cover plate 210, where filter element 211 filters them, and the purified gas is discharged from the equipment.

[0044] In summary, the rotating auger inside the hopper can quantitatively and stably transport sand to the distribution box, ensuring the continuity of the production process and improving production efficiency. The fan, in conjunction with the heating wire, allows hot air to circulate within the drying chamber to dry the sand, improving drying efficiency and quality, and ensuring the sand's moisture content meets standards. The sieve plate screens the material entering the drying chamber, preventing larger particles or impurities from entering, ensuring the purity and quality of the dried sand. The cover plate and filter element design filters the hot air and dust generated during the drying process, purifying the exhaust gas and reducing environmental pollution. The inspection pipe and matching pull rods, sealing plates, and spring assemblies facilitate maintenance and repair of the distribution box, reducing equipment maintenance costs.
