Abstract
Description
Technical Field
[0001] The utility model belongs to the field of screening equipment, in particular to a screen frame for an ultrasonic screening machine. Background Art
[0002] Ultrasonic screening machine is a screening equipment that combines screening machine with ultrasonic vibration. It is widely used in the field of pharmaceutical production, such as screening of drug intermediates. The structure of ultrasonic screening machine currently used includes multiple superimposed screen frames. Two adjacent screen frames are fixed together by a tie ring. A discharge trough is set on the side wall of each screen frame. In order to facilitate the connection of discharged materials, this discharge trough is generally designed as a longer structure so that the discharge port is far away from the screen frame. The discharge trough is usually directly welded and fixed on the screen frame. Although this structure is simple to produce and process, it still has certain disadvantages. Especially when used for drug screening, drugs with different components will be screened. This requires that the inside of the screen frame needs to be thoroughly cleaned after screening a drug to avoid contamination of the drugs screened later. However, the discharge trough directly welded on the screen frame is not convenient for thorough cleaning due to its long length, which can easily cause contamination to the drugs screened later and affect the safety of drug use.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0025] As shown in the figure, a sieve frame for an ultrasonic screening machine includes a sieve frame body 1. A through groove 101 is provided on the side wall of the sieve frame body 1. A U-shaped support plate 3 is fixedly connected to the outer side wall of the sieve frame body 1 corresponding to the through groove 101. A discharge chute body 2 with a hollow structure inside is inserted into the support plate 3, and the front end opening of the discharge chute body 2 is butted against the through groove 101. Limit blocks 5 capable of pressing the discharge chute body 2 are provided on both sides of the support plate 3. A discharge port 202 is provided downward at the end of the discharge chute body 2. In this embodiment, the discharge chute body 2 is corresponding to the through groove 101 of the sieve frame body 1 and is inserted and fixed on the support plate 3 outside the sieve frame body 1. The support plate 3 is used to fix and support the discharge chute body 2. Compared with the structure in which the discharge chute body 2 is directly fixed on the sieve frame body 1, the service life of the discharge chute body 2 is effectively extended, and the discharge chute body 2 is prevented from sagging and deforming after long-term use. The limit blocks 5 arranged on the upper side of the support plate 3 are used to limit and fix the discharge chute body 2, ensuring the installation stability of the discharge chute body 2. At the same time, it is also convenient to disassemble and assemble the discharge chute body 2.
[0026] A groove 301 communicating end to end is provided on the inner side wall of the support plate 3. Limit convex edges 201 are fixedly connected to the left and right side walls and the bottom of the discharge chute body 2 corresponding to the groove 301, and the limit convex edges 201 are embedded in the groove 301.
[0027] A sealing strip is coated along the inner wall of the groove 301, so that when the limit convex edge 201 is inserted into the groove 301, it plays a role of sealing and increasing friction, and prevents the discharge chute body 2 from jumping out of the support plate 3 when the ultrasonic screening machine is working.
[0028] The four peripheral edges of the through groove 101 are abutted against the four peripheral side walls of the front end opening of the discharge chute body 2, or are aligned with the four peripheral edges of the front end opening of the discharge chute body 2. A sealing gasket is fixedly connected to the outer side wall of the sieve frame body 1 around the through groove 101, further increasing the friction between the discharge chute body 2 and the sieve frame body 1, ensuring the installation stability of the discharge chute body 2 on the sieve frame body 1, and also ensuring the sealing performance of the connection between the two.
[0029] Connecting columns 4 are vertically and fixedly connected to the upper surfaces of both sides of the support plate 3. End caps 401 are fixedly connected to the tops of the connecting columns 4. The limit blocks 5 are in a U-shaped structure and are sleeved on the connecting columns 4. A spring 6 is sleeved on the connecting columns 4 between the limit blocks 5 and the end caps 401, and the spring 6 is in a compressed state. In this embodiment, the limit blocks 5 are set in a U-shaped structure. Through holes are provided on the upper and lower sides of the limit blocks 5 corresponding to the connecting columns 4, and the limit blocks 5 are sleeved on the connecting columns 4 through the through holes, which is convenient for the operator to hook the limit blocks 5 with fingers to apply force and move the limit blocks 5. When it is necessary to remove the discharge chute body 2, the two limit blocks 5 are moved out of the upper side of the discharge chute body 2; a spring 6 that is always in a compressed state is arranged between the upper side of the limit block 5 and the end cap 401, generating a pressing force on the limit block 5, so that the limit block 5 can press the discharge chute body 2.
[0030] A rubber pad is bonded and fixed to the bottom of the limit block 5. When the limit block 5 abuts against the upper side of the discharge chute 2, the vibration of the ultrasonic screening machine will cause the spring 6 to vibrate as well. At this time, the rubber pad increases the friction between the limit block 5 and the discharge chute 2. At the moment when the spring 6 is compressed again, the limit block 5 is prevented from being displaced and detached from the discharge chute 2.
[0031] A handle 7 is fixedly connected to the upper side of the discharge chute body 2, which is convenient for removing the discharge chute body 2 upward from the screen frame body 1. In this embodiment, there are two handles 7, which are fixedly connected to both sides of the discharge chute body 2, so that the operator can apply force to remove or install the discharge chute body 2 smoothly.
[0032] The left and right sides of the discharge chute body 2 corresponding to the support plate 3 are both configured as planar structures parallel to the side walls of the support plate 3 to enhance the connection stability with the support plate 3 .
[0033] The working process of this embodiment is as follows:
[0034] The discharge chute body 2 is inserted downwardly on the support plate 3, and through the cooperation of the limiting ridge 201, the groove 301 and the sealing strip between the discharge chute body 2 and the support plate 3, the use of the sealing gasket between the screen frame body 1 and the discharge chute body 2, and the cooperation of the limiting block 5, the rubber pad, the spring 6 on the upper side of the support plate 3 and the discharge chute body 2, the discharge chute body 2 is stably installed on the outside of the screen frame body 1.
[0035] When it is necessary to remove the discharge chute body 2 for thorough cleaning of the interior, the operator moves the limit block 5 upward with force, and the spring 6 is compressed upward to separate the limit block 5 from the discharge chute body 2, and then rotates the limit block 5 outward so that after the operator releases his hand, the limit block 5 abuts against the upper side of the support plate 3 under the action of the spring 6. At this time, the discharge chute body 2 completely loses the restraint of the limit block 5, and the operator grasps the handle 7 and forcefully lifts the discharge chute body 2 upward to complete the separation of the discharge chute body 2 and the screen frame body 1.
[0036] 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.
