Description

Technical Field

[0001] The utility model relates to the technical field of cement processing devices, in particular to a multifunctional batching screening device for cement production. Background Art

[0002] Cement is an indispensable building material in the construction field and is generally the main raw material for making concrete. In order to ensure that the size and shape of cement particles meet the standard requirements, cement needs to be screened for large particles and impurities when used.

[0003] The Chinese patent "A screening device for cement production with anti-caking function" authorization announcement number is "CN212524874U". When the driving mechanism is working, the screening box is driven to shake left and right, so as to screen the cement. The cement will gradually fall out of the screening box through the screen. At the same time, when the screening box moves left and right, it will collide under the action of the vibration mechanism, which will cause the screening box to vibrate. Therefore, the screening speed of cement is faster. When the cement leaves the screening box, impurities such as nylon thread ends can be effectively screened out and remain in the screening box to avoid affecting the quality of concrete in the later stage. When the grinding mechanism is working, it can squeeze and grind large pieces of cement in the screening box to avoid cement agglomeration and will not affect the production of concrete.

[0004] While grinding cement, it will squeeze the cement so that part of the cement enters the filter holes. Since cement is in powder form, the cement that enters the filter holes through squeezing tends to form lumps, causing the filter holes to be blocked, thus affecting the cement screening operation.

[0005] Therefore, a multifunctional batching screening device for cement production is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a multifunctional cement production ingredient screening device in order to solve the above-mentioned problems, thereby improving the problem that while grinding cement, cement is squeezed so that part of the cement enters the filter holes. Since cement is powdery, the cement that enters the filter holes through squeezing is prone to form lumps, causing the filter holes to be blocked, thereby affecting the cement screening operation.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, a multifunctional ingredient screening device for cement production, comprising: a screening barrel, the inner wall of the screening barrel is provided with a slide groove, and a screening mechanism is arranged inside the screening barrel; wherein, the screening mechanism comprises a motor fixedly connected to the surface of the screening barrel, a screening plate is slidably connected to the inner wall of the screening barrel, a circular ring is fixedly connected to the middle part of the top end of the screening plate, a moving ring is rotatably connected to the inner wall of the circular ring, a rotating shaft is slidably connected to the inner wall of the moving ring, a grinding frame is fixedly connected to the upper end of the surface of the moving ring, an anti-blocking component is arranged at the bottom end of the screening plate, and a screening component is arranged on the surface of the screening barrel.

When grinding and screening cement, under the action of the limiting groove and the limiting block, the rotating shaft drives the moving ring to rotate synchronously, when the cylinder and the filter hole of the screening plate coincide, the first spring is used to automatically enter the filter hole to push out the agglomerated cement in the filter hole, and avoid the agglomerated cement on the inner wall of the filter hole causing the filter hole to be blocked, thereby improving the cement screening efficiency, and at the same time, when the cement is being screened, the filter holes of the screening plate are cleaned in sequence by driving the cylinder to rotate through the round rod, thereby ensuring that the screening operation of the screening plate is not affected while cleaning.

[0009] Preferably, a second spring is fixedly connected between the bottom end of the limit block and the inner bottom wall of the limit groove, a trigger ring is fixedly connected to the surface of the moving ring, and the bottom end of the trigger ring is in contact with the top end of the circular ring. Under the action of the second spring, it is beneficial to keep the trigger ring in contact with the circular ring, thereby ensuring that the moving ring moves up and down synchronously when the screen plate moves up and down, and it is beneficial to ensure that the top end of the moving rod is always in contact with the bottom end of the screen plate when the screen plate moves up and down.

The cooperation between the cam and the slide frame is conducive to driving the screening plate to move up and down to perform cement screening operations, and the screening efficiency of cement is improved through vibration screening. At the same time, under the action of the slider and the slide slot, it is conducive to realizing the limit of the screening plate when it moves up and down.

Under the action of the bevel gear and the pulley, when the screening plate is performing the screening operation, it is conducive to driving the rotating shaft to rotate synchronously, driving the anti-blocking component to operate, and improving the consistency of the device during operation.

[0012] Preferably, a protective plate is fixedly connected to the inner wall of the sieve plate. When the sieve plate moves up and down, the protective plate is driven to move up and down synchronously.

[0014] Preferably, the top of the moving rod is curved into a spherical shape, and the filter hole of the sieve plate is in a flat-top cone shape. When the moving rod enters the filter hole and continues to rotate, the spherical shape at the top of the moving rod cooperates with the filter hole shape, which helps the filter hole to better push the moving rod downward.

[0015] The beneficial effects of the utility model are:

[0016] 1. When grinding and screening cement, under the action of the limit groove and the limit block, the rotating shaft drives the moving ring to rotate synchronously.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] When implementing: Figure 1-5 As shown, a multifunctional ingredient screening device for cement production includes: a screening barrel 1, the inner wall of the screening barrel 1 is provided with a slide groove 101, and a screening mechanism 2 is arranged inside the screening barrel 1; wherein, the screening mechanism 2 includes a motor 201 fixedly connected to the surface of the screening barrel 1, a screening plate 202 is slidably connected to the inner wall of the screening barrel 1, a circular ring 203 is fixedly connected to the middle of the top of the screening plate 202, a moving ring 205 is rotatably connected to the inner wall of the circular ring 203, a rotating shaft 204 is slidably connected to the inner wall of the moving ring 205, a grinding frame 206 is fixedly connected to the upper end of the surface of the moving ring 205, an anti-blocking component 207 is arranged at the bottom end of the screening plate 202, and a screening component 208 is arranged on the surface of the screening barrel 1.

[0027] A feed port is provided at the top of the screening barrel 1, and a discharge port is provided at the bottom. When cement needs to be screened, the cement is poured in through the feed port. At this time, the motor 201 is started to drive the screening component 208 to run, driving the screening plate 202 to perform screening operations. At the same time, when the screening component 208 is running, the anti-blocking component 207 is synchronously driven to run.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the anti-blocking assembly 207 includes a round rod 2071 fixedly connected to the lower end of the surface of the moving ring 205, and the upper end of the surface of the round rod 2071 is fixedly connected to the cylinders 2072 distributed in an equal row, and the inner wall of the cylinder 2072 is slidably connected to the moving rod 2073, and the first spring 2074 is fixedly connected between the bottom end of the moving rod 2073 and the inner bottom wall of the cylinder 2072. The inner wall of the moving ring 205 is provided with a limiting groove 2075, and the surface of the rotating shaft 204 is fixedly connected to a limiting block 2076, and the limiting block 2076 is slidably connected to the inner wall of the limiting groove 2075, and the second spring 2077 is fixedly connected between the bottom end of the limiting block 2076 and the inner bottom wall of the limiting groove 2075, and the surface of the moving ring 205 is fixedly connected to a trigger ring 2078, and the bottom end of the trigger ring 2078 is in contact with the top of the round ring 203. The top of the rotating shaft 204 passes through the screening barrel 1 and is fixedly connected with a bevel gear 20711. There are two bevel gears 20711, which are meshed with each other. One end of one of the bevel gears 20711 and the surface of the output shaft of the motor 201 are fixedly connected with a pulley 2079, and a synchronous belt 20710 is arranged between the two pulleys 2079. The surface of the grinding frame 206 is fixedly connected with a protrusion 2061 distributed in an annular shape, and the shape of the protrusion 2061 is a cone. The top of the moving rod 2073 is curved in a spherical shape, and the filter hole opened in the screening plate 202 is in the shape of a flat-top cone.

[0029] When the motor 201 is started, the pulley 2079 on the output shaft surface of the motor 201 is driven to rotate, and the other pulley 2079 is driven to rotate under the action of the synchronous belt 20710, thereby driving one of the bevel gears 20711 to rotate. When one of the bevel gears 20711 rotates, it drives the other bevel gear 20711 to rotate, thereby driving the rotating shaft 204 to rotate. When the rotating shaft 204 rotates, the moving ring 205 is synchronously rotated under the action of the limit block 2076 and the limit groove 2075. When the moving ring 205 rotates, it drives the grinding frame 206 and the round rod 207 1 rotates synchronously, the grinding frame 206 is arranged above the screening plate 202, the round rod 2071 is arranged below the screening plate 202, the grinding frame 206 and the round rod 2071 are staggered, and the cement agglomerated in the screening barrel 1 is crushed by the rotation of the grinding frame 206. At the same time, the position of the cylinder 2072 corresponds to the position of the filter hole on the screening plate 202. When the round rod 2071 rotates to drive the cylinder 2072 to move to coincide with the filter hole on the screening plate 202, under the action of the first spring 2074, the moving rod 2073 will enter the filter hole to push out the cement in the filter hole to prevent the cement from clogging the filter hole.

[0030] When the screening plate 202 moves upward, the circular ring 203 will push the trigger ring 2078 to drive the movable ring 205 to move upward. When the screening plate 202 moves downward, under the action of the second spring 2077, the bottom end of the trigger ring 2078 is always pressed against the top end of the circular ring 203. Therefore, the round rod 2071 and the grinding frame 206 will move up and down synchronously with the screening plate 202 while rotating.

[0031] like Figure 2 and Figure 3 As shown, the screening assembly 208 includes a cam 2081 fixedly connected to the output shaft of the motor 201, a slider 2082 is slidably connected to the inner wall of the slide 101, one side of the slider 2082 is fixedly connected to the surface of the screening plate 202, the other side of the slider 2082 penetrates the screening barrel 1 and is fixedly connected to a slide frame 2083, and the cam 2081 is arranged inside the slide frame 2083. A protective plate 2084 is fixedly connected to the inner wall of the screening plate 202.

[0032] When the cement is screened, the motor 201 is started, and the output shaft of the motor 201 drives the cam 2081 to rotate. Since the inner bottom wall and the inner top wall of the sliding frame 2083 are in contact with the surface of the cam 2081, when the cam 2081 rotates, it drives the sliding frame 2083 to move back and forth up and down. The sliding groove 101 is a through groove. When the sliding frame 2083 moves back and forth up and down, it drives the slider 2082 to move back and forth up and down synchronously, thereby driving the screening plate 202 to move back and forth up and down to screen the cement.

[0033] When the utility model is in use, when it is necessary to screen cement, the cement is poured in through the feed port, and the motor 201 is started at this time. The output shaft of the motor 201 drives the cam 2081 to rotate, so that the slide frame 2083 moves up and down reciprocatingly, so that the slider 2082 drives the screening plate 202 to move up and down reciprocatingly to screen the cement. When the screening plate 202 moves up and down, the trigger ring 2078 and the second spring 2077 drive the moving ring 205 to move up and down synchronously, so that the top end of the moving rod 2073 is always in contact with the bottom end of the screening plate 202. At the same time, when the motor 201 is started, the pulley 2079 and the synchronous belt 2077 are in contact with each other. 0710 and the bevel gear 20711 drive the rotating shaft 204 to rotate synchronously. When the rotating shaft 204 rotates, the movable ring 205 rotates synchronously under the action of the limit block 2076 and the limit groove 2075. When the movable ring 205 rotates, the grinding frame 206 and the round rod 2071 are driven to rotate synchronously. The cement agglomerated into the screening barrel 1 is crushed by the rotation of the grinding frame 206. When the round rod 2071 rotates and drives the cylinder 2072 to move to coincide with the filter holes on the screening plate 202, under the action of the first spring 2074, the movable rod 2073 will enter the filter holes and push out the cement in the filter holes to prevent the cement from clogging the filter holes.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
