Description

Technical Field

[0001] This utility model belongs to the field of material separation technology, and in particular relates to an internal circulation horizontal screw centrifuge. Background Technology

[0002] The internal circulation horizontal screw centrifuge is a highly efficient separation device widely used in industries such as chemical, pharmaceutical, food, and environmental protection. It primarily utilizes centrifugal force to separate materials.

[0003] Traditional centrifuges may encounter problems such as low efficiency and incomplete separation when processing mixtures containing particles of different densities. In addition, material blockage is also a common problem, especially in continuous operation. Early centrifuge designs often lacked sufficient flexibility to adapt to different working environments or specific operational needs, such as adjusting the height of the separation chamber for easy maintenance or making adaptive adjustments according to site conditions. In the process of material feeding, separation and unloading, many steps require manual intervention, which not only increases labor costs but may also lead to operational errors or safety hazards.

[0004] To address these issues, we provide an internal circulation horizontal spiral centrifuge. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an internal circulation horizontal screw centrifuge, comprising a support assembly, a separation chamber mounted on the upper part of the support assembly, and a rotating drum rotatably disposed inside the separation chamber. The support assembly includes a base plate, a sleeve fixed at the upper corner of the base plate, and a support column vertically disposed inside the sleeve. The separation chamber includes a shell fixed to the top of the support column, an end cap covering the upper opening of the shell, an observation window embedded in the front of the end cap, and a guide hopper fixed to the bottom of the shell. The rotating drum includes a storage body, a separation body disposed at the end of the storage body, and a discharge port disposed around the edge of the separation body.

[0007] The present invention is further configured such that the sleeve has a hollow cavity inside, the sleeve is fitted onto the outside of the support column, both the sleeve and the support column have positioning holes for fastener installation, and the support column is locked by the fastener sleeve.

[0008] The present invention is further configured such that the guide hopper is a conical shell structure, and the guide hopper is in communication with the interior of the shell.

[0009] The present invention is further configured such that a discharge port is provided at the bottom of the feed hopper, and the discharge port is equipped with an automatic discharge valve.

[0010] The present invention is further configured such that a support plate is fixed on one side of the housing, and a drive motor is fixed on the support plate. The output shaft of the drive motor is connected to the end of the storage body via a shaft. A shaft is also fixed at the end of the separation body, and the shaft cooperates with a bearing seat fixed at the middle position of the upper side of the housing.

[0011] The present invention is further configured such that a spiral feeding structure is provided in the closed cavity formed by the storage body and the separation body, wherein the feeding direction of the spiral feeding structure is opposite to the material separation direction, and an inlet is provided on the periphery of the storage body.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting a support column that is raised and lowered inside the sleeve, allows the height of the separation chamber to be adjusted according to actual needs. This makes it convenient for operators to flexibly adjust the height of the separation chamber as needed, facilitating maintenance, cleaning, and adaptation to different working environments. For example, in situations where space is limited, the height can be lowered to save space; while when it is necessary to access the separation chamber more easily for maintenance, it can be raised.

[0014] 2. This utility model avoids the risk of material flying out by setting an end cap to cover the opening at the top of the shell and embedding an observation window. It also facilitates monitoring the separation process and timely detection of any abnormalities. The end cap effectively prevents accidental splashing of materials during the separation process, ensuring the safety of the working environment. At the same time, the observation window allows operators to monitor the internal situation in real time without opening the equipment.

[0015] 3. This utility model, by setting a conical material guide hopper and equipping it with an automatic unloading valve at the bottom, helps to realize an automated unloading process, reduce manual intervention, and the conical structure facilitates the centralized collection and discharge of materials. The automatic unloading valve enables unattended continuous operation, greatly improving work efficiency, while also reducing labor costs and operational risks.

[0025] Example

[0026] Please see Figure 1-4 This utility model relates to an internal circulation horizontal screw centrifuge, comprising a support assembly 100, a separation chamber 200 mounted on the upper part of the support assembly 100, and a rotating drum 300 rotatably disposed inside the separation chamber 200. The support assembly 100 includes a base plate 101, a sleeve 102 fixed at the upper corner of the base plate 101, and a support column 103 vertically disposed inside the sleeve 102. The separation chamber 200 includes a housing 201 fixed to the top of the support column 103, an end cap 202 covering the upper opening of the housing 201, an observation window 203 embedded in the front of the end cap 202, and a guide hopper 204 fixed to the bottom of the housing 201. The rotating drum 300 includes a storage body 304, a separation body 305 disposed at the end of the storage body 304, and a discharge port 306 disposed around the edge of the separation body 305.

[0027] The base plate 101 serves as the basic support platform for the entire equipment, ensuring the stability and safety of the centrifuge during operation. The support column 103 is raised and lowered inside the sleeve 102, allowing the operator to adjust the height of the separation chamber 200 according to actual needs. This not only facilitates the operation and maintenance of the equipment but also adapts to different working environments. The shell 201 constitutes the main space for material separation. The end cover 202 is used to shield the upper part of the separation chamber 200 to prevent material from flying out and also to assist in material collection. The observation window 203 allows for direct viewing of the interior of the shell 201, facilitating monitoring of the separation process and timely detection of any abnormalities. The guide hopper 204 is used to collect and discharge the separated material. The storage body 304 rotates synchronously with the separation body 305. The powerful centrifugal force generated by the storage body gradually separates the heavier material into the separation body 305 and discharges it from the outlet 306.

[0028] Specifically, a support plate 301 is fixed on one side of the housing 201, and a drive motor 302 is fixed on the support plate 301. The output shaft of the drive motor 302 is connected to the end of the storage body 304 via a shaft member 307. A shaft member 307 is also fixed to the end of the separation body 305. The shaft member 307 cooperates with a bearing seat 303 fixed at the middle position of the upper side of the housing 201. A spiral feeding structure is provided in the closed cavity formed by the storage body 304 and the separation body 305. The feeding direction of the spiral feeding structure is opposite to the material separation direction. This reverse motion effectively enhances the separation efficiency. A feed inlet is provided on the periphery of the storage body 304.

[0029] After the drive motor 302 is started, the storage body 304 and the separation body 305 rotate synchronously under the transmission action of the shaft 307. The heavier materials inside the storage body 304 are gathered into the separation body 305. The screw feeding structure rotates synchronously with the drum 300 and transports the material accumulated in the separation body 305 back to the storage body 304. This prevents blockage and also enables cyclic separation, improving separation efficiency.

[0030] Furthermore, the guide hopper 204 has a conical shell structure and is connected to the interior of the shell 201. The bottom of the guide hopper 204 is provided with a discharge port 205, which is equipped with an automatic discharge valve 206.

[0031] The sleeve 102 has a hollow interior and is fitted onto the outside of the support column 103. Both the sleeve 102 and the support column 103 have positioning holes for fastener installation. The support column 103 is locked by the fastener sleeve 102. The positioning holes in both the sleeve 102 and the support column 103 are used to install fasteners, ensuring the firmness of the connection between the two and preventing loosening caused by vibration or load changes.
